Raw Blame History

Create executable phase prompts (PLAN.md files) for a roadmap phase with integrated research and verification. Default flow: Research (if needed) -> Plan -> Verify -> Done. Orchestrates gsd-phase-researcher, gsd-planner, and gsd-plan-checker agents with a revision loop (max 3 iterations).

<required_reading> Read all files referenced by the invoking prompt's execution_context before starting.

@~~/.claude/gsd-core/references/ui-brand.md @~~/.claude/gsd-core/references/revision-loop.md @~~/.claude/gsd-core/references/gate-prompts.md @~~/.claude/gsd-core/references/agent-contracts.md @~/.claude/gsd-core/references/gates.md </required_reading>

<available_agent_types> Valid GSD subagent types (use exact names — do not fall back to 'general-purpose'):

gsd-phase-researcher — Researches technical approaches for a phase
gsd-pattern-mapper — Analyzes codebase for existing patterns, produces PATTERNS.md
gsd-planner — Creates detailed plans from phase scope
gsd-plan-checker — Reviews plan quality before execution </available_agent_types>

<runtime_compatibility> Subagent spawning — top-level Claude Code: The Agent tool IS available in a top-level Claude Code session. Always spawn gsd-phase-researcher, gsd-planner, and gsd-plan-checker as separate Agent() calls. Never absorb these roles inline. Role separation is required regardless of --chain or --auto — those options suppress interactive prompts only; they NEVER authorize collapsing plan roles into the orchestrator context.

Backgrounded Claude Code (via manager/autonomous): The calling workflow (manager.md / autonomous.md) already runs plan-phase inline via Skill() on Claude Code so that the plan-checker subagent can still spawn. plan-phase itself does not need to detect this case.

#1009 caveat (discuss-phase early-exit): The "display the command and exit" instruction near ## 4 applies only to the discuss-phase early-exit path. It does NOT authorize inline role performance for any plan-phase agents.

Other runtimes: Do not pre-judge Agent availability by introspection. Always attempt the actual Agent() call for gsd-phase-researcher, gsd-planner, and gsd-plan-checker. Only a real tool-unavailable error returned by Agent() is a reliable absence signal — never stop based on a self-assessed "I think Agent is unavailable." If the call fails with a tool-unavailable error, log the gap and stop — do NOT collapse researcher/planner/checker roles inline. Independent agent contexts are required for the plan-checker gate to be meaningful. </runtime_compatibility>

0. Git Branch Invariant

Do not create, rename, or switch git branches during plan-phase. Branch identity is established at discuss-phase and is owned by the user's git workflow. A phase rename in ROADMAP.md is a plan-level change only — it does not mutate git branch names. If phase_slug in the init JSON differs from the current branch name, that is expected and correct; leave the branch unchanged.

1. Initialize

Load all context in one call (paths only to minimize orchestrator context):

_GSD_SHIM_NAME="gsd-tools.cjs"; _GSD_RUNTIME_ROOT="${RUNTIME_DIR:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}"; GSD_TOOLS="${_GSD_RUNTIME_ROOT}/gsd-core/bin/${_GSD_SHIM_NAME}"; if [ -f "$GSD_TOOLS" ]; then gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${_GSD_RUNTIME_ROOT}/.claude/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${_GSD_RUNTIME_ROOT}/.claude/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${_GSD_RUNTIME_ROOT}/.codex/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${_GSD_RUNTIME_ROOT}/.codex/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif command -v gsd-tools >/dev/null 2>&1; then GSD_TOOLS="$(command -v gsd-tools)"; gsd_run() { "$GSD_TOOLS" "$@"; }; elif [ -f "$HOME/.claude/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="$HOME/.claude/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${HERMES_HOME:-$HOME/.hermes}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${HERMES_HOME:-$HOME/.hermes}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${CURSOR_CONFIG_DIR:-$HOME/.cursor}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${CURSOR_CONFIG_DIR:-$HOME/.cursor}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${CODEX_HOME:-$HOME/.codex}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${CODEX_HOME:-$HOME/.codex}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${GEMINI_CONFIG_DIR:-$HOME/.gemini}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${GEMINI_CONFIG_DIR:-$HOME/.gemini}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${COPILOT_CONFIG_DIR:-$HOME/.copilot}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${COPILOT_CONFIG_DIR:-$HOME/.copilot}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${WINDSURF_CONFIG_DIR:-$HOME/.codeium/windsurf}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${WINDSURF_CONFIG_DIR:-$HOME/.codeium/windsurf}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${AUGMENT_CONFIG_DIR:-$HOME/.augment}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${AUGMENT_CONFIG_DIR:-$HOME/.augment}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${TRAE_CONFIG_DIR:-$HOME/.trae}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${TRAE_CONFIG_DIR:-$HOME/.trae}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${QWEN_CONFIG_DIR:-$HOME/.qwen}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${QWEN_CONFIG_DIR:-$HOME/.qwen}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${CODEBUDDY_CONFIG_DIR:-$HOME/.codebuddy}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${CODEBUDDY_CONFIG_DIR:-$HOME/.codebuddy}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${CLINE_CONFIG_DIR:-$HOME/.cline}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${CLINE_CONFIG_DIR:-$HOME/.cline}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${GROK_AGENTS_HOME:-$HOME/.agents}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${GROK_AGENTS_HOME:-$HOME/.agents}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${ANTIGRAVITY_CONFIG_DIR:-$HOME/.gemini/antigravity}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${ANTIGRAVITY_CONFIG_DIR:-$HOME/.gemini/antigravity}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${OPENCODE_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/opencode}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${OPENCODE_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/opencode}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${KILO_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/kilo}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${KILO_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/kilo}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; else echo "ERROR: gsd-tools.cjs not found at $GSD_TOOLS and gsd-tools is not on PATH. Run: npx -y @opengsd/gsd-core@latest --claude --local" >&2; exit 1; fi; if [ -n "${CLAUDE_ENV_FILE:-}" ] && [ -n "${GSD_TOOLS:-}" ]; then printf "export PATH='%s':\"\$PATH\"\n" "${GSD_TOOLS%/*}" >> "$CLAUDE_ENV_FILE" 2>/dev/null || true; fi
GRAN_PARAM=""; if [[ "$ARGUMENTS" =~ (^|[[:space:]])--granularity[[:space:]]+([^[:space:]-][^[:space:]]*) ]]; then GRAN_PARAM="--granularity ${BASH_REMATCH[2]}"; fi
INIT=$(gsd_run query init.plan-phase "$PHASE" $GRAN_PARAM)
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi
AGENT_SKILLS_RESEARCHER=$(gsd_run query agent-skills gsd-phase-researcher)
AGENT_SKILLS_PLANNER=$(gsd_run query agent-skills gsd-planner)
AGENT_SKILLS_CHECKER=$(gsd_run query agent-skills gsd-plan-checker)

TDD_MODE=$(gsd_run query config-get workflow.tdd_mode 2>/dev/null || echo "false")
MVP_MODE_CFG=$(gsd_run query config-get workflow.mvp_mode 2>/dev/null || echo "false")

When TDD_MODE is true, the planner agent is instructed to apply type: tdd to eligible tasks using heuristics from references/tdd.md. The planner's <required_reading> is extended to include @~/.claude/gsd-core/references/tdd.md so gate enforcement rules are available during planning.

When CONTEXT_WINDOW >= 500000, the planner prompt includes the 3 most recent prior phase CONTEXT.md and SUMMARY.md files PLUS any phases explicitly listed in the current phase's Depends on: field in ROADMAP.md. Explicit dependencies always load regardless of recency (e.g., Phase 7 declaring Depends on: Phase 2 always sees Phase 2's context). Bounded recency keeps the planner's context budget focused on recent work.

Parse JSON for: researcher_model, planner_model, checker_model, research_enabled, plan_checker_enabled, nyquist_validation_enabled, commit_docs, text_mode, phase_found, phase_dir, phase_number, phase_name, phase_slug, padded_phase, has_research, has_context, has_reviews, has_plans, plan_count, phase_status (#3569), planning_exists, roadmap_exists, phase_req_ids, response_language, granularity.

If response_language is set: Include response_language: {value} in all spawned subagent prompts so any user-facing output stays in the configured language.

File paths (for <files_to_read> blocks): state_path, roadmap_path, requirements_path, context_path, research_path, verification_path, uat_path, reviews_path. These are null if files don't exist.

If planning_exists is false: Error — run /gsd:new-project first.

1.5. Closed-Phase Gate (#3569)

The init JSON includes phase_status — one of Pending | Planned | In Progress | Executed | Complete | Needs Review. Complete means the phase has all summaries AND a VERIFICATION.md with status: passed. Replanning a closed phase silently rewrites plan docs that no longer match the shipped code, so the workflow must hard-stop here unless the operator explicitly overrides.

Parse phase_status from the init JSON, then:

FORCE_REPLAN=false
if [[ "$ARGUMENTS" =~ (^|[[:space:]])--force([[:space:]]|$) ]]; then
  FORCE_REPLAN=true
fi

if [ "${phase_status}" = "Complete" ]; then
  if [[ "$ARGUMENTS" =~ (^|[[:space:]])--reviews([[:space:]]|$) ]]; then
    # --reviews on a closed phase is never legitimate — concerns belong in a
    # new phase or issue against the closed phase's commits.
    cat <<EOF >&2
Phase ${phase_number} (${phase_name}) is already CLOSED (VERIFICATION status: passed).
/gsd:plan-phase --reviews cannot replan a closed phase. If the review surfaced
real concerns, open a follow-up phase or file an issue against the closed
phase's commits. There is no --force override for --reviews on a closed phase.
EOF
    exit 1
  fi
  if [ "$FORCE_REPLAN" != "true" ]; then
    cat <<EOF >&2
Phase ${phase_number} (${phase_name}) is already CLOSED (VERIFICATION status: passed).
Replanning a closed phase will overwrite plan docs that no longer match the
shipped code. If you intentionally want to replan over closed work, re-run
with: /gsd:plan-phase ${phase_number} --force

Otherwise, to view what shipped, see: ${verification_path}
EOF
    exit 1
  fi
  # FORCE_REPLAN=true: continue, but emit a banner so the operator sees the
  # decision in the transcript and in any committed plan docs.
  echo "WARNING: Replanning CLOSED phase ${phase_number} under --force. Verify the closeout was wrong before committing new plan docs." >&2
fi

The gate fires only on Complete. Executed and Needs Review are not gated — those states mean planning was finished but verification did not pass, and replanning is a legitimate next step.

2. Parse and Normalize Arguments

Extract from $ARGUMENTS: phase number (integer or decimal like 2.1), flags (--research, --skip-research, --research-phase <N>, --gaps, --skip-verify, --skip-ui, --prd <filepath>, --ingest <path-or-glob>, --ingest-format <auto|nygard|madr|narrative>, --reviews, --text, --bounce, --skip-bounce, --chunked, --mvp, --tdd, --granularity <coarse|standard|fine>, --force (override closed-phase gate, see §1.5)).

--research-phase <N> — research-only mode (#3042 + #3044). When this flag is present, parse <N> as the phase number (overrides any positional phase argument), set RESEARCH_ONLY=true, and treat the rest of this workflow as a research-dispatch only — the planner spawn (step 8), plan-checker, verification, gaps, bounce, and post-planning-gaps blocks all skip on RESEARCH_ONLY. Use this for cross-phase research, doc review before committing to a planning approach, and correction-without-replanning loops. Replaces the deleted /gsd-research-phase command.

In research-only mode, two modifiers control behavior when RESEARCH.md already exists:

--research — force-refresh re-research without prompting. Re-spawns the researcher unconditionally and overwrites the existing RESEARCH.md. (This is the existing --research flag's standard "force re-research" semantics, reused here.)
--view — view-only: print existing RESEARCH.md to stdout, do not spawn the researcher. Sets VIEW_ONLY=true. Cheapest mode for the correction-without-replanning loop. If RESEARCH.md does not exist, error with a hint to drop --view.

RESEARCH_ONLY=false
VIEW_ONLY=false
if [[ "$ARGUMENTS" =~ --research-phase[[:space:]]+([0-9]+(\.[0-9]+)?) ]]; then
  RESEARCH_ONLY=true
  PHASE="${BASH_REMATCH[1]}"
fi
if $RESEARCH_ONLY && [[ "$ARGUMENTS" =~ (^|[[:space:]])--view([[:space:]]|$) ]]; then
  VIEW_ONLY=true
fi

--granularity <coarse|standard|fine> — CLI override (#703). When present, this value is the resolved granularity passed to the planner — it wins over any per-phase granularities.<type> config, top-level granularity config, or project defaults. The init JSON always includes a granularity field reflecting the resolved value; read it from there. Invalid values (anything other than coarse, standard, fine) cause an error at the CLI boundary.

Set TEXT_MODE=true if --text is present in $ARGUMENTS OR text_mode from init JSON is true. When TEXT_MODE is active, replace every AskUserQuestion call with a plain-text numbered list and ask the user to type their choice number. This is required for Claude Code remote sessions (/rc mode) where TUI menus don't work through the Claude App.

MVP_MODE resolution. Resolve MVP_MODE once via the centralized phase.mvp-mode query verb. Precedence (first hit wins): CLI flag → ROADMAP.md **Mode:** mvp → workflow.mvp_mode config → false. The verb is the single source of truth — do not re-implement the chain.

MVP_FLAG_ARG=""
if [[ "$ARGUMENTS" =~ (^|[[:space:]])--mvp([[:space:]]|$) ]]; then MVP_FLAG_ARG="--cli-flag"; fi
if [[ "$ARGUMENTS" =~ (^|[[:space:]])--tdd([[:space:]]|$) ]]; then TDD_MODE=true; fi

Defer the phase.mvp-mode query until PHASE is finalized (after explicit argument parsing/fallback phase detection + validation). The verb returns true|false; full result also exposes source (cli_flag | roadmap | config | none) for diagnostics. Mode is all-or-nothing per phase (PRD decision Q1).

Walking Skeleton gate. When MVP_MODE=true AND phase_number == "01" AND there are zero prior phase summaries (new project), the planner runs in Walking Skeleton mode (per PRD decision Q2 — new projects only). Detect with:

WALKING_SKELETON=false
if [ "$MVP_MODE" = "true" ] && [ "$padded_phase" = "01" ]; then
  PRIOR_SUMMARIES=$(gsd_run query phases.list --pick summaries_total 2>/dev/null || echo "0")
  if [ "$PRIOR_SUMMARIES" = "0" ]; then WALKING_SKELETON=true; fi
fi

When WALKING_SKELETON=true:

Planner is instructed to produce SKELETON.md in the phase directory alongside PLAN.md. The template lives at ~/.claude/gsd-core/references/skeleton-template.md — the planner reads it when producing SKELETON.md (lazy; not loaded on non-skeleton runs).
The plan must scaffold project + routing + one real DB read/write + one real UI interaction + dev deployment — the thinnest possible end-to-end working slice.

Interaction with --prd <filepath>. --mvp and --prd compose. The PRD express path (Step 3.5) creates CONTEXT.md from the PRD file and continues to research; the Walking Skeleton gate fires independently from the conditions above. When both are active on Phase 1 of a new project, the planner receives WALKING_SKELETON=true and PRD-derived context simultaneously — the PRD informs what the skeleton should prove. No precedence is needed; the two signals are orthogonal. See references/mvp-concepts.md for the broader interaction map.

Extract express-path args from $ARGUMENTS: PRD_FILE (--prd <filepath>), INGEST_PATH (--ingest <path-or-glob>), and optional INGEST_FORMAT (--ingest-format <auto|nygard|madr|narrative>, default auto).

--prd and --ingest are mutually exclusive. If both are present, error and exit: Invalid arguments: cannot combine \--prd` with `--ingest`.`

If no phase number: Detect next unplanned phase from roadmap.

If phase_found is false: Validate phase exists in ROADMAP.md. If valid, create the directory using expected_phase_dir from init (includes project_code prefix when set):

mkdir -p "${expected_phase_dir}"

Set phase_dir="${expected_phase_dir}" after creation.

Existing artifacts from init: has_research, has_plans, plan_count.

Set CHUNKED_MODE from flag or config:

CHUNKED_CFG=$(gsd_run query config-get workflow.plan_chunked 2>/dev/null || echo "false")
CHUNKED_MODE=false
if [[ "$ARGUMENTS" =~ --chunked ]] || [[ "$CHUNKED_CFG" == "true" ]]; then
  CHUNKED_MODE=true
fi

2.5. Validate `--reviews` Prerequisite

Skip if: No --reviews flag.

If --reviews AND --gaps: Error — cannot combine --reviews with --gaps. These are conflicting modes.

If --reviews AND has_reviews is false (no REVIEWS.md in phase dir):

Error:

No REVIEWS.md found for Phase {N}. Run reviews first:

/gsd:review --phase {N}

Then re-run /gsd:plan-phase {N} --reviews

Exit workflow.

3. Validate Phase

PHASE_INFO=$(gsd_run query roadmap.get-phase "${PHASE}")

If found is false: Error with available phases. If found is true: Extract phase_number, phase_name, goal from JSON.

Now that PHASE is finalized, resolve MVP mode:

MVP_MODE=$(gsd_run query phase.mvp-mode "${PHASE}" $MVP_FLAG_ARG --pick active)

3.5. Handle PRD Express Path

Skip if: No --prd flag in arguments.

If --prd <filepath> provided:

Read the PRD file:

PRD_CONTENT=$(cat "$PRD_FILE" 2>/dev/null)
if [ -z "$PRD_CONTENT" ]; then
  echo "Error: PRD file not found: $PRD_FILE"
  exit 1
fi

Using PRD: {PRD_FILE}
Generating CONTEXT.md from requirements...

Parse the PRD content and generate CONTEXT.md. The orchestrator should:
- Extract all requirements, user stories, acceptance criteria, and constraints from the PRD
- Map each to a locked decision (everything in the PRD is treated as a locked decision)
- Identify any areas the PRD doesn't cover and mark as "Claude's Discretion"
- Extract canonical refs from ROADMAP.md for this phase, plus any specs/ADRs referenced in the PRD — expand to full file paths (MANDATORY)
- Create CONTEXT.md in the phase directory
Write CONTEXT.md:

# Phase [X]: [Name] - Context

**Gathered:** [date]
**Status:** Ready for planning
**Source:** PRD Express Path ({PRD_FILE})

<domain>
## Phase Boundary

[Extracted from PRD — what this phase delivers]

</domain>

<decisions>
## Implementation Decisions

{For each requirement/story/criterion in the PRD:}
### [Category derived from content]
- [Requirement as locked decision]

### Claude's Discretion
[Areas not covered by PRD — implementation details, technical choices]

</decisions>

<canonical_refs>
## Canonical References

**Downstream agents MUST read these before planning or implementing.**

[MANDATORY. Extract from ROADMAP.md and any docs referenced in the PRD.
Use full relative paths. Group by topic area.]

---

*Phase: XX-name*
*Context gathered: [date] via PRD Express Path*

Commit:

gsd_run query commit "docs(${padded_phase}): generate context from PRD" --files "${phase_dir}/${padded_phase}-CONTEXT.md"

Set context_content to the generated CONTEXT.md content and continue to step 5 (Handle Research).

Effect: This completely bypasses step 4 (Load CONTEXT.md) since we just created it. The rest of the workflow (research, planning, verification) proceeds normally with the PRD-derived context.

3.6. Handle ADR Ingest Express Path

Skip if: No --ingest flag in arguments.

If --ingest <path-or-glob> provided:

Display banner: GSD ► ADR Ingest Express Path with {INGEST_PATH} and {INGEST_FORMAT}.
Parse each resolved ADR through gsd-core/bin/lib/adr-parser.cjs (--input, --format) and collect normalized records.
Status gate: reject superseded/rejected/deprecated; warn on proposed; missing status defaults to accepted.
Empty-decisions fallback: if all parsed ADRs have zero decisions[], emit ADR ingest produced no locked decisions; fall back to discuss-phase for this phase. and exit with /gsd:discuss-phase {N} guidance.
Generate CONTEXT.md using <domain>, <decisions>, <canonical_refs>, <specifics>, <deferred>, <scope_fence>, map consequences_positive[] to Success Criteria and consequences_negative[] to Risk Summary, and include **Source:** ADR Ingest Express Path ({INGEST_PATH}).
Commit with gsd-tools.cjs query commit "docs(${padded_phase}): generate context from ADR ingest" --files "${phase_dir}/${padded_phase}-CONTEXT.md" and set context_content; continue to step 5.

Effect: This bypasses step 4 (Load CONTEXT.md) since CONTEXT.md was synthesized from ADR input.

4. Load CONTEXT.md

Skip if: PRD express path or ADR ingest express path was used (CONTEXT.md already created in step 3.5/3.6).

Check context_path from init JSON.

If context_path is not null, display: Using phase context from: ${context_path}

If context_path is null (no CONTEXT.md exists):

Read discuss mode for context gate label:

DISCUSS_MODE=$(gsd_run query config-get workflow.discuss_mode 2>/dev/null || echo "discuss")

If TEXT_MODE is true, present as a plain-text numbered list:

No CONTEXT.md found for Phase {X}. Plans will use research and requirements only — your design preferences won't be included.

1. Continue without context — Plan using research + requirements only
[If DISCUSS_MODE is "assumptions":]
2. Gather context (assumptions mode) — Analyze codebase and surface assumptions before planning
[If DISCUSS_MODE is "discuss" or unset:]
2. Run discuss-phase first — Capture design decisions before planning

Enter number:

Otherwise use AskUserQuestion:

header: "No context"
question: "No CONTEXT.md found for Phase {X}. Plans will use research and requirements only — your design preferences won't be included. Continue or capture context first?"
options:
- "Continue without context" — Plan using research + requirements only If DISCUSS_MODE is "assumptions":
- "Gather context (assumptions mode)" — Analyze codebase and surface assumptions before planning If DISCUSS_MODE is "discuss" (or unset):
- "Run discuss-phase first" — Capture design decisions before planning

If "Continue without context": Proceed to step 5. If "Run discuss-phase first": IMPORTANT: Do NOT invoke discuss-phase as a nested Skill/Task call — AskUserQuestion does not work correctly in nested subcontexts (#1009). Instead, display the command and exit so the user runs it as a top-level command:

Run this command first, then re-run /gsd:plan-phase {X} ${GSD_WS}:

/gsd:discuss-phase {X} ${GSD_WS}

Exit the plan-phase workflow. Do not continue.

4.5. Resolve AI-SPEC Artifact

AI integration activation is owned by the ai-integration capability's plan:pre step hook. The plan-phase host only discovers existing artifacts here so the planner can consume them; it must not read the capability's config key directly.

AI_SPEC_FILE=$(ls "${PHASE_DIR}"/*-AI-SPEC.md 2>/dev/null | head -1)
AI_SPEC_PATH="${AI_SPEC_FILE}"
FRAMEWORK_LINE=""
if [ -n "$AI_SPEC_FILE" ]; then
  FRAMEWORK_LINE=$(grep "Selected Framework:" "${AI_SPEC_FILE}" | head -1)
fi

If AI_SPEC_FILE is non-empty, pass AI_SPEC_PATH and FRAMEWORK_LINE to the planner in step 8 so it can reference the AI design contract. If it is empty, the active ai-integration capability hook in step 5.6 handles any AI-system nudge or /gsd:ai-integration-phase dispatch.

5. Handle Research

Skip if: --gaps flag or --skip-research flag or --reviews flag.

5.0. Research-Only Modifiers (`--view`, `--research`)

Skip if: RESEARCH_ONLY is false.

Three branches in research-only mode (--research-phase <N>):

--view: print RESEARCH.md to stdout, no spawn, exit. If RESEARCH.md is missing, error with: --view requires an existing RESEARCH.md; drop --view to spawn the researcher.
--research (force-refresh): re-spawn researcher unconditionally — fall through to "Spawn gsd-phase-researcher" below.
Neither flag AND has_research=true: auto-use the existing research and exit cleanly — do not prompt, do not re-spawn. Emit RESEARCH.md already exists for Phase ${PHASE}, using it. To force-refresh, re-invoke with --research; to print, re-invoke with --view. Path: ${research_path} then exit. The explicit-flag escape hatches cover any deviation; this matches §5.1's promptless auto-use of existing research, removing the §5.0/§5.1 inconsistency (#159).

if [[ "$VIEW_ONLY" == "true" ]]; then
  [[ -f "$research_path" ]] || { echo "Error: --view requires an existing RESEARCH.md (Phase ${PHASE}). Drop --view to spawn the researcher."; exit 1; }
  cat "$research_path"; exit 0
fi

5.1. Standard Research Decision

Skip if RESEARCH_ONLY=true (the research-only mode in 5.0 already determined the path: spawn or exit). Without this guard, an LLM following the workflow could fall through into "use existing, skip to step 6" → planner spawn, violating the research-only contract. CR #3045 finding: this gate makes the early-exit unreachable from any non-research-only branch.

If has_research is true (from init) AND no --research flag: Use existing, skip to step 6.

If RESEARCH.md missing OR --research flag:

If no explicit flag (--research or --skip-research) and not --auto: Ask the user whether to research, with a contextual recommendation based on the phase:

If TEXT_MODE is true, present as a plain-text numbered list:

Research before planning Phase {X}: {phase_name}?

1. Research first (Recommended) — Investigate domain, patterns, and dependencies before planning. Best for new features, unfamiliar integrations, or architectural changes.
2. Skip research — Plan directly from context and requirements. Best for bug fixes, simple refactors, or well-understood tasks.

Enter number:

Otherwise use AskUserQuestion:

AskUserQuestion([
  {
    question: "Research before planning Phase {X}: {phase_name}?",
    header: "Research",
    multiSelect: false,
    options: [
      { label: "Research first (Recommended)", description: "Investigate domain, patterns, and dependencies before planning. Best for new features, unfamiliar integrations, or architectural changes." },
      { label: "Skip research", description: "Plan directly from context and requirements. Best for bug fixes, simple refactors, or well-understood tasks." }
    ]
  }
])

If user selects "Skip research": skip to step 6.

If --auto and research_enabled is false: Skip research silently (preserves automated behavior).

◆ Spawning researcher... (runs in a subagent — no output until it returns, ~1–5 min; expected, not a freeze)

Spawn gsd-phase-researcher

PHASE_DESC=$(gsd_run query roadmap.get-phase "${PHASE}" --pick section)
if [ -z "${PLAN_PRE_HOOKS_JSON:-}" ]; then
  PLAN_PRE_HOOKS_JSON=$(gsd_run loop render-hooks plan:pre --raw)

Find the active research step hook in PLAN_PRE_HOOKS_JSON. Use the hook's fragment.inline as the prompt template and substitute the phase fields below before spawning its declared ref.agent.

{research_hook.fragment.inline}

Agent(
  prompt=filled_research_hook_fragment,
  subagent_type=research_hook.ref.agent,
  model="{researcher_model}",
  description="Research Phase {phase}"
)

Handle Researcher Return

## RESEARCH COMPLETE: Display confirmation, continue to step 6
## RESEARCH BLOCKED: Display blocker, offer: 1) Provide context, 2) Skip research, 3) Abort

Research-Only Early Exit (`--research-phase`)

Skip if: RESEARCH_ONLY is false (the default).

If RESEARCH_ONLY=true: the user invoked /gsd:plan-phase --research-phase <N> for research-only mode. Do not continue to Section 5.5+ (validation strategy, planner, plan-checker, verification, gaps, bounce, post-planning-gaps). Print the research-complete summary and exit cleanly:

✓ Research-only mode complete (#3042)

  Phase:       ${PHASE}
  RESEARCH.md: ${research_path}

Re-run /gsd:plan-phase ${PHASE} to plan the phase using this research,
or /gsd:plan-phase ${PHASE} --research to refresh research and plan.

This exits the workflow. The planner / plan-checker / verifier blocks below are skipped.

5.5. Create Validation Strategy

Skip if nyquist_validation_enabled is false OR research_enabled is false.

If research_enabled is false and nyquist_validation_enabled is true: warn "Nyquist validation enabled but research disabled — VALIDATION.md cannot be created without RESEARCH.md. Plans will lack validation requirements (Dimension 8)." Continue to step 6.

But Nyquist is not applicable for this run when all of the following are true:

research_enabled is false
has_research is false
no --research flag was provided

In that case: skip validation-strategy creation entirely. Do not expect RESEARCH.md or VALIDATION.md for this run, and continue to Step 6.

grep -l "## Validation Architecture" "${PHASE_DIR}"/*-RESEARCH.md 2>/dev/null || true

If found:

Read template: ~/.claude/gsd-core/templates/VALIDATION.md
Write to ${PHASE_DIR}/${PADDED_PHASE}-VALIDATION.md (use Write tool)
Fill frontmatter: {N} → phase number, {phase-slug} → slug, {date} → current date
Verify:

test -f "${PHASE_DIR}/${PADDED_PHASE}-VALIDATION.md" && echo "VALIDATION_CREATED=true" || echo "VALIDATION_CREATED=false"

If VALIDATION_CREATED=false: STOP — do not proceed to Step 6
If commit_docs: commit "docs(phase-${PHASE}): add validation strategy"

If not found: Warn and continue — plans may fail Dimension 8.

5.55. Security Threat Model Gate

SECURITY_CFG=$(gsd_run query config-get workflow.security_enforcement --raw 2>/dev/null || echo "true")
SECURITY_ASVS=$(gsd_run query config-get workflow.security_asvs_level --raw 2>/dev/null || echo "1")
SECURITY_BLOCK=$(gsd_run query config-get workflow.security_block_on --raw 2>/dev/null || echo "high")

If SECURITY_CFG is false: Skip to step 5.6.

If SECURITY_CFG is true: Display banner:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 GSD ► SECURITY THREAT MODEL REQUIRED (ASVS L{SECURITY_ASVS})
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Each PLAN.md must include a <threat_model> block.
Block on: {SECURITY_BLOCK} severity threats.
Opt out: set security_enforcement: false in .planning/config.json

Continue to step 5.6. Security config is passed to the planner in step 8.

5.6. Plan:Pre Capability Dispatch and UI Design Contract Gate

PLAN_PRE_HOOKS_JSON=${PLAN_PRE_HOOKS_JSON:-$(gsd_run loop render-hooks plan:pre --raw)}
HOOKS_JSON="$PLAN_PRE_HOOKS_JSON"

Read the activeHooks array directly from PLAN_PRE_HOOKS_JSON / HOOKS_JSON (in-context — do NOT invoke a shell pipeline).

Branch 1 — all plan:pre hooks inactive (activeHooks is empty or absent): Skip to step 6.

Generic step hook dispatch contract: For each active entry where kind == "step":

If ref.skill is set, dispatch with Skill(skill="gsd-${ref.skill}", args="${PHASE} --auto ${GSD_WS}") when pipeline mode allows auto-chaining. Prepend gsd- to ref.skill — ui-phase → gsd-ui-phase.
If ref.agent is set, dispatch with Agent(prompt=filled_hook_fragment, subagent_type=ref.agent, model="{researcher_model}"). Use the hook's fragment.inline as the prompt body and fill phase fields before spawning.
The research hook is handled by §5.1's research decision. The pattern-mapper hook is handled by §7.8 after RESEARCH_PATH is known. Future plan:pre agent hooks use the same ref.agent fragment contract.

AI integration capability: If the active ai-integration step hook is present, AI_SPEC_PATH is empty, and the phase goal contains AI keywords (agent, llm, rag, chatbot, embedding, langchain, llamaindex, crewai, langgraph, openai, anthropic, vector, eval, ai system), then:

In pipeline / --auto mode, invoke the hook's ref.skill via Skill(skill="gsd-${ref.skill}", args="${PHASE} --auto ${GSD_WS}").
In manual mode, display the existing non-blocking /gsd:ai-integration-phase {N} recommendation and let the user continue planning without AI-SPEC or stop to run the capability workflow first.

Run the UI deterministic gate whenever any plan:pre UI hook is active — including the step-only case (workflow.ui_safety_gate off). (check.query = "ui.plan-gate"; router normalizes dots→hyphens.)

GATE=$(gsd_run check ui-plan-gate "${PHASE}" --raw)

Read frontend, hasUiSpec, and block from GATE.

Branch 2 — no frontend indicators (frontend is false): Skip silently to step 5.7.

Branch 3 — UI-SPEC already exists (hasUiSpec is true):

UI_SPEC_FILE=$(ls "${PHASE_DIR}"/*-UI-SPEC.md 2>/dev/null | head -1)
UI_SPEC_PATH="${UI_SPEC_FILE}"

Display: Using UI design contract: ${UI_SPEC_PATH}. Continue to step 6.

Branch 4 — --skip-ui in $ARGUMENTS: Skip silently to step 6.

Branches 5 & 6 — frontend detected, UI-SPEC missing, no --skip-ui.

Read the ephemeral auto-chain flag:

AUTO_CHAIN=$(gsd_run query check auto-mode --pick auto_chain_active 2>/dev/null || echo "false")

Branch 5 — AUTO_CHAIN is true (pipeline / --auto): Fire each active UI step hook — runs independently of whether a gate is active (covers {ui_phase:true,ui_safety_gate:false}). For each entry in activeHooks (in array order) where kind == "step" and ref.skill is set:

Skill(skill="gsd-${ref.skill}", args="${PHASE} --auto ${GSD_WS}")

After all UI step hooks return, re-read:

UI_SPEC_FILE=$(ls "${PHASE_DIR}"/*-UI-SPEC.md 2>/dev/null | head -1)
UI_SPEC_PATH="${UI_SPEC_FILE}"

Continue to step 6.

Branch 6 — AUTO_CHAIN is false (manual): generic gate handling. For each entry in activeHooks where kind == "gate" and blocking is true: if block:true (from GATE), output the block below and EXIT the plan-phase workflow. If no active blocking gate (e.g. workflow.ui_safety_gate is off), continue to step 6 — no block.

Output this markdown directly (not as a code block):

## ⚠ UI-SPEC.md missing for Phase {N}
▶ Recommended next step:
`/gsd:ui-phase {N} ${GSD_WS}` — generate UI design contract before planning
───────────────────────────────────────────────
Also available:
- `/gsd:plan-phase {N} --skip-ui ${GSD_WS}` — plan without UI-SPEC (not recommended for frontend phases)

Exit the plan-phase workflow. Do not continue.

5.7. Schema Push Detection Gate

Check if any files in the phase scope match schema patterns:

PHASE_SECTION=$(gsd_run query roadmap.get-phase "${PHASE}" --pick section 2>/dev/null)

Scan PHASE_SECTION, CONTEXT.md (if loaded), and RESEARCH.md (if exists) for file paths matching these ORM patterns:

ORM	File Patterns
Payload CMS	`src/collections/*/.ts`, `src/globals/*/.ts`
Prisma	`prisma/schema.prisma`, `prisma/schema/*.prisma`
Drizzle	`drizzle/schema.ts`, `src/db/schema.ts`, `drizzle/*.ts`
Supabase	`supabase/migrations/*.sql`
TypeORM	`src/entities/*/.ts`, `src/migrations/*/.ts`

Also check if any existing PLAN.md files for this phase already reference these file patterns in files_modified.

If schema-relevant files detected:

Set SCHEMA_PUSH_REQUIRED=true and SCHEMA_ORM={detected_orm}.

Determine the push command for the detected ORM:

ORM	Push Command	Non-TTY Workaround
Payload CMS	`npx payload migrate`	`CI=true PAYLOAD_MIGRATING=true npx payload migrate`
Prisma	`npx prisma db push`	`npx prisma db push --accept-data-loss` (if destructive)
Drizzle	`npx drizzle-kit push`	`npx drizzle-kit push`
Supabase	`supabase db push`	Set `SUPABASE_ACCESS_TOKEN` env var
TypeORM	`npx typeorm migration:run`	`npx typeorm migration:run -d src/data-source.ts`

Inject the following into the planner prompt (step 8) as an additional constraint:

<schema_push_requirement>
**[BLOCKING] Schema Push Required**

This phase modifies schema-relevant files ({detected_files}). The planner MUST include
a `[BLOCKING]` task that runs the database schema push command AFTER all schema file
modifications are complete but BEFORE verification.

- ORM detected: {SCHEMA_ORM}
- Push command: {push_command}
- Non-TTY workaround: {env_hint}
- If push requires interactive prompts that cannot be suppressed, flag the task for
  manual intervention with `autonomous: false`

This task is mandatory — the phase CANNOT pass verification without it. Build and
type checks will pass without the push (types come from config, not the live database),
creating a false-positive verification state.
</schema_push_requirement>

Display: Schema files detected ({SCHEMA_ORM}) — [BLOCKING] push task will be injected into plans

If no schema-relevant files detected: Skip silently to step 6.

6. Check Existing Plans

ls "${PHASE_DIR}"/*-PLAN.md 2>/dev/null || true

If exists AND --reviews flag: Skip prompt — go straight to replanning (the purpose of --reviews is to replan with review feedback).

If exists AND no --reviews flag: Offer: 1) Add more plans, 2) View existing, 3) Replan from scratch.

7. Use Context Paths from INIT

Extract from INIT JSON:

_gsd_field() { node -e "const o=JSON.parse(process.argv[1]); const v=o[process.argv[2]]; process.stdout.write(v==null?'':String(v))" "$1" "$2"; }
STATE_PATH=$(_gsd_field "$INIT" state_path)
ROADMAP_PATH=$(_gsd_field "$INIT" roadmap_path)

VERIFICATION_PATH=$(_gsd_field "$INIT" verification_path)
UAT_PATH=$(_gsd_field "$INIT" uat_path)
CONTEXT_PATH=$(_gsd_field "$INIT" context_path)
REVIEWS_PATH=$(_gsd_field "$INIT" reviews_path)
PATTERNS_PATH=$(_gsd_field "$INIT" patterns_path)

SPIKE_FINDINGS_PATH=$(ls ./.claude/skills/spike-findings-*/SKILL.md 2>/dev/null | head -1 || true)
SKETCH_FINDINGS_PATH=$(ls ./.claude/skills/sketch-findings-*/SKILL.md 2>/dev/null | head -1 || true)

# Resolve the phase SPEC (carries the ## Edge Coverage section the planner lifts covered/
# backstop edges from). UNCONDITIONAL — must NOT live in §4.5 Check AI-SPEC, which is skipped
# on non-AI phases; gating it there silently starves the planner of the SPEC (#550 review).
# Glob the plain phase SPEC, excluding the -AI-SPEC.md / -UI-SPEC.md variants.
PHASE_DIR_FOR_SPEC=$(_gsd_field "$INIT" phase_dir)
SPEC_FILE=$(ls "${PHASE_DIR_FOR_SPEC}"/*-SPEC.md 2>/dev/null | grep -Ev -- '-(AI|UI)-SPEC\.md$' | head -1)
SPEC_PATH="${SPEC_FILE}"

7.5. Verify Nyquist Artifacts

Skip if nyquist_validation_enabled is false OR research_enabled is false.

Also skip if all of the following are true:

research_enabled is false
has_research is false
no --research flag was provided

In that no-research path, Nyquist artifacts are not required for this run.

VALIDATION_EXISTS=$(ls "${PHASE_DIR}"/*-VALIDATION.md 2>/dev/null | head -1)

If missing and Nyquist is still enabled/applicable — ask user:

Re-run: /gsd:plan-phase {PHASE} --research ${GSD_WS}
Disable Nyquist with the exact command: gsd-tools.cjs query config-set workflow.nyquist_validation false
Continue anyway (plans fail Dimension 8)

Proceed to Step 7.8 (or Step 8 if pattern mapper is disabled) only if user selects 2 or 3.

7.8. Spawn gsd-pattern-mapper Agent (Optional)

Pattern mapper activation is owned by the pattern-mapper capability's plan:pre step hook. Read PLAN_PRE_HOOKS_JSON and skip if no active step hook has capId == "pattern-mapper" and ref.agent == "gsd-pattern-mapper". Also skip if no CONTEXT.md and no RESEARCH.md exist for this phase (nothing to extract file lists from).

If PATTERNS.md already exists (PATTERNS_PATH is non-empty from step 7): Skip to step 8 (use existing).

Use the active pattern-mapper hook's fragment.inline as the prompt template and substitute the phase fields below before spawning its declared ref.agent.

{pattern_mapper_hook.fragment.inline}

Spawn with:

Agent(
  prompt=filled_pattern_mapper_hook_fragment,
  subagent_type=pattern_mapper_hook.ref.agent,

Handle return:

## PATTERN MAPPING COMPLETE: Update PATTERNS_PATH to the created file path, continue to step 8.
Any error or empty return: Log warning, continue to step 8 without patterns (non-blocking).

After pattern mapper completes, update the path variable:

PATTERNS_PATH="${PHASE_DIR}/${PADDED_PHASE}-PATTERNS.md"

7.9. Regenerate API-SURFACE.md (intel gate)

INTEL_CFG=$(gsd_run query config-get intel.enabled 2>/dev/null || echo "false")
# false (absent = false) → API_SURFACE_PATH stays empty; step-8 planner entry omitted
if [ "$INTEL_CFG" = "true" ]; then

For each current actionable finding in REVIEWS.md, the planner MUST either:
- incorporate it into a PLAN.md task, `<action>`, `<acceptance_criteria>`, `<verify>`, `must_haves`, threat model, or artifact list; or
- explicitly document a deferral/rejection rationale in the relevant PLAN.md so the executor and reviewer can see the decision.

Historical findings already incorporated, explicitly deferred/rejected in PLAN.md, or marked fully resolved do not require new plan changes.

<downstream_consumer>
Output consumed by /gsd:execute-phase. Plans need:
- Frontmatter (wave, depends_on, files_modified, autonomous)
- Tasks in XML format with read_first and acceptance_criteria fields (MANDATORY on every task)
- Verification criteria
- must_haves for goal-backward verification
- If the SPEC has an `## Edge Coverage` section, lift every `covered` edge's acceptance criterion into `must_haves.truths`, and every `backstop` edge into `must_haves.truths` as a non-inferable check (note it needs a held-out/property-based test). `unresolved` edges are explicit assumptions — surface them in the plan, do not silently drop them.
- **"Artifacts this phase produces" section (MANDATORY)** — list every symbol this phase creates: decorators, classes, functions, CLI flags, struct/dataclass fields, new file paths. The plan-review-convergence source-grounding pass reads this section to exclude newly-created symbols from drift verification; omitting it causes new symbols to be flagged for acknowledgement.
</downstream_consumer>

<deep_work_rules>
## Anti-Shallow Execution Rules (MANDATORY)

Every task MUST include these fields — they are NOT optional:

1. **`<read_first>`** — Files the executor MUST read before touching anything. Always include:
   - The file being modified (so executor sees current state, not assumptions)
   - Any "source of truth" file referenced in CONTEXT.md (reference implementations, existing patterns, config files, schemas)
   - Any file whose patterns, signatures, types, or conventions must be replicated or respected

2. **`<acceptance_criteria>`** — Verifiable conditions that prove the task was done correctly. Rules:
   - Every criterion must be checkable as a source assertion, behavior assertion, test command, or CLI output
   - NEVER use subjective language ("looks correct", "properly configured", "consistent with")
   - Include exact strings, patterns, values, command outputs, or observable behavior where that is the right proof
   - Examples:
     - Code: `auth.py contains def verify_token(` / `test_auth.py exits 0`
     - Behavior: `POST /api/auth/login returns 200 + httpOnly JWT cookie for valid credentials`
     - Config: `.env.example contains DATABASE_URL=` / `Dockerfile contains HEALTHCHECK`
     - Docs: `README.md contains '## Installation'` / `API.md lists all endpoints`
     - Infra: `deploy.yml has rollback step` / `docker-compose.yml has healthcheck for db`

3. **`<action>`** — Must include CONCRETE values, not references. Rules:
   - NEVER say "align X with Y", "match X to Y", "update to be consistent" without specifying the exact target state
   - Include concrete identifiers and reference values: config keys, function signatures, SQL table names, class names, import paths, env vars, endpoint paths, etc.
   - If CONTEXT.md has a comparison table or expected values, copy only the target identifiers/values needed to remove ambiguity
   - Do not include full file contents, fenced code blocks, or complete implementations in `<action>`
   - The executor should understand the intended target state from `<action>` and use `<read_first>` files for current implementation details, patterns, and source-of-truth context

**Why this matters:** Executor agents work from the plan text. Vague instructions like "update the config to match production" produce shallow one-line changes. Concrete instructions like "add DATABASE_URL, set POOL_SIZE=20, add REDIS_URL, and read config/runtime.ts before editing" produce complete work without turning the planner into the executor.

If CHUNKED_MODE is false (default): Spawn the planner as a single long-lived Agent:

Agent(
  prompt=filled_prompt,
  subagent_type="gsd-planner",

)

If CHUNKED_MODE is true: Skip the Agent() call above — proceed to step 8.5 instead.

8.5. Chunked Planning Mode

Skip if CHUNKED_MODE is false.

Chunked mode splits the single long-lived planner Agent run into a short outline Agent run followed by N short per-plan Agent runs. Each run is bounded to ~3–5 min; each plan is committed individually for crash resilience. If any run hangs and the terminal is force-killed, rerunning /gsd:plan-phase {N} --chunked resumes from the last successfully committed plan.

Intended for new or in-progress chunked runs. To recover plans already written by a prior non-chunked run, use step 6's "Add more plans" or proceed directly to /gsd:execute-phase — don't start a fresh chunked run over existing non-chunked plans.

8.5.1 Outline Phase (outline-only mode, ~2 min)

Resume detection: If ${PHASE_DIR}/${PADDED_PHASE}-PLAN-OUTLINE.md already exists and is valid (contains the ## OUTLINE COMPLETE marker), skip this sub-step — the outline already exists from a previous run. Proceed directly to 8.5.2.

OUTLINE_FILE="${PHASE_DIR}/${PADDED_PHASE}-PLAN-OUTLINE.md"
if [[ -f "$OUTLINE_FILE" ]] && grep -q "^## OUTLINE COMPLETE" "$OUTLINE_FILE"; then

  prompt="{same planning_context as step 8, plus:}

  **Chunked mode: outline-only.**
  Do NOT write any PLAN.md files in this Task.
  Write only: {PHASE_DIR}/{PADDED_PHASE}-PLAN-OUTLINE.md

Any other return or empty: Display error. Offer: 1) Retry outline, 2) Stop.

8.5.2 Per-Plan Tasks (single-plan mode, ~3-5 min each)

For each plan entry extracted from PLAN-OUTLINE.md:

  Return: ## PLAN COMPLETE with the plan ID.",
  subagent_type="gsd-planner",

)

Verify disk: Check ${PHASE_DIR}/{plan_id}-PLAN.md exists. If missing: offer 1) Retry, 2) Stop.

Commit per-plan:

gsd_run query commit "docs(${PADDED_PHASE}): plan ${plan_id} (chunked)" --files "${PHASE_DIR}/${plan_id}-PLAN.md"

After all N plans are written and committed, treat this as ## PLANNING COMPLETE and continue to step 9.

9. Handle Planner Return

## PLANNING COMPLETE: Display plan count. If --skip-verify or plan_checker_enabled is false (from init): skip to step 13. Otherwise: step 10.
## PHASE SPLIT RECOMMENDED: The planner determined the phase exceeds the context budget for full-fidelity implementation of all source items. Handle in step 9b.
## ⚠ Source Audit: Unplanned Items Found: The planner's multi-source coverage audit found items from REQUIREMENTS.md, RESEARCH.md, ROADMAP goal, or CONTEXT.md decisions that are not covered by any plan. Handle in step 9c.
## CHECKPOINT REACHED: Present to user, get response, spawn continuation (step 12)
## PLANNING INCONCLUSIVE: Show attempts, offer: Add context / Retry / Manual
Empty / truncated / no recognized marker: → Filesystem fallback (step 9a).

9a. Filesystem Fallback (Planner)

Triggered when: Agent() returns but the return contains no recognized marker (## PLANNING COMPLETE, ## PHASE SPLIT RECOMMENDED, ## ⚠ Source Audit, ## CHECKPOINT REACHED, ## PLANNING INCONCLUSIVE).

DISK_PLANS=$(ls "${PHASE_DIR}"/*-PLAN.md 2>/dev/null | wc -l | tr -d ' ')

If DISK_PLANS > 0: The planner wrote plans to disk but the Agent() return was empty or truncated (the Windows stdio hang pattern — the subagent finished but the return never arrived). Display:

◆ Planner wrote {DISK_PLANS} plan(s) to disk but did not emit a PLANNING COMPLETE marker.
  This is a known Windows stdio hang pattern — work is likely recoverable.

  Plans found on disk:
  {ls output of *-PLAN.md}

Offer 3 options:

Accept plans — treat as ## PLANNING COMPLETE and continue through step 9 ## PLANNING COMPLETE handling (so --skip-verify / plan_checker_enabled=false are honored — may skip to step 13 rather than step 10)
Retry planner — re-spawn the planner with the same prompt (return to step 8)
Stop — exit; user can re-run /gsd:plan-phase {N} to resume

If DISK_PLANS is 0 and no marker: The planner produced no output. Treat as ## PLANNING INCONCLUSIVE and handle accordingly.

9b. Handle Phase Split Recommendation

When the planner returns ## PHASE SPLIT RECOMMENDED, it means the phase's source items exceed the context budget for full-fidelity implementation. The planner proposes groupings.

Extract from planner return:

Proposed sub-phases (e.g., "17a: processing core (D-01 to D-19)", "17b: billing + config UX (D-20 to D-27)")
Which source items (REQ-IDs, D-XX decisions, RESEARCH items) go in each sub-phase
Why the split is necessary (context cost estimate, file count)

Present to user:

## Phase {X} exceeds context budget for full-fidelity implementation

The planner found {N} source items that exceed the context budget when
planned at full fidelity. Instead of reducing scope, we recommend splitting:

**Option 1: Split into sub-phases**
- Phase {X}a: {name} — {items} ({N} source items, ~{P}% context)
- Phase {X}b: {name} — {items} ({M} source items, ~{Q}% context)

**Option 2: Proceed anyway** (planner will attempt all, quality may degrade past 50% context)

**Option 3: Prioritize** — you choose which items to implement now,
rest become a follow-up phase

Use AskUserQuestion with these 3 options.

If "Split": Use /gsd:phase --insert to create the sub-phases, then replan each. If "Proceed": Return to planner with instruction to attempt all items at full fidelity, accepting more plans/tasks. If "Prioritize": Use AskUserQuestion (multiSelect) to let user pick which items are "now" vs "later". Create CONTEXT.md for each sub-phase with the selected items.

9c. Handle Source Audit Gaps

When the planner returns ## ⚠ Source Audit: Unplanned Items Found, it means items from REQUIREMENTS.md, RESEARCH.md, ROADMAP goal, or CONTEXT.md decisions have no corresponding plan.

Extract from planner return:

Each unplanned item with its source artifact and section
The planner's suggested options (A: add plan, B: split phase, C: defer with confirmation)

Present each gap to user. For each unplanned item:

## ⚠ Unplanned: {item description}

Source: {RESEARCH.md / REQUIREMENTS.md / ROADMAP goal / CONTEXT.md}
Details: {why the planner flagged this}

Options:
1. Add a plan to cover this item (recommended)
2. Split phase — move to a sub-phase with related items
3. Defer — add to backlog (developer confirms this is intentional)

Use AskUserQuestion for each gap (or batch if multiple gaps).

If "Add plan": Return to planner (step 8) with instruction to add plans covering the missing items, preserving existing plans. If "Split": Use /gsd:phase --insert for overflow items, then replan. If "Defer": Record in CONTEXT.md ## Deferred Ideas with developer's confirmation. Proceed to step 10.

11. Handle Checker Return

## VERIFICATION PASSED: Display confirmation, proceed to step 13.
## ISSUES FOUND: Display issues, check iteration count, proceed to step 12.
Empty / truncated / no recognized marker: → Filesystem fallback (step 11a).

Thinking partner for architectural tradeoffs (conditional): If features.thinking_partner is enabled, scan the checker's issues for architectural tradeoff keywords ("architecture", "approach", "strategy", "pattern", "vs", "alternative"). If found:

The plan-checker flagged an architectural decision point:

Apply this to the revision? [Yes] / [No, I'll decide]

If yes: include the recommendation in the revision prompt. If no: proceed to revision loop as normal. If thinking_partner disabled: skip this block entirely.

11a. Filesystem Fallback (Checker)

Triggered when: Checker Agent() returns but the return contains neither ## VERIFICATION PASSED nor ## ISSUES FOUND.

DISK_PLANS=$(ls "${PHASE_DIR}"/*-PLAN.md 2>/dev/null | wc -l | tr -d ' ')

If DISK_PLANS > 0: Plans exist on disk; the checker return was empty or truncated (the Windows stdio hang pattern — the subagent finished but the return never arrived). Display:

◆ Checker return was empty or truncated. {DISK_PLANS} plan(s) exist on disk.
  This is a known Windows stdio hang pattern — checker may have completed without returning.

Offer 3 options:

Accept verification — treat as ## VERIFICATION PASSED and continue to step 13
Retry checker — re-spawn the checker with the same prompt (return to step 10)
Stop — exit; user can re-run /gsd:plan-phase {N} to resume

If DISK_PLANS is 0: No plans on disk — something is seriously wrong. Display error and stop.

12. Revision Loop (Max 3 Iterations)

Track iteration_count (starts at 1 after initial plan + check). Track prev_issue_count (initialized to Infinity before the loop begins). Track stall_reentry_count (starts at 0; incremented each time "Adjust approach" re-enters step 8).

If iteration_count < 3:

Parse issue count from checker return: count BLOCKER + WARNING entries in the YAML issues block (structured output from gsd-plan-checker). If the checker's return contains no YAML issues block (i.e., the plan was approved with no issues), treat issue_count as 0 and skip the stall check — the plan passed. Proceed to step 13.

Display: Revision iteration {N}/3 -- {blocker_count} blockers, {warning_count} warnings

Stall detection: If issue_count >= prev_issue_count: Display: Revision loop stalled — issue count not decreasing ({issue_count} issues remain after {N} iterations)

If stall_reentry_count < 2: Ask user: Question: "Issues remain after {N} revision attempts with no progress. Proceed with current output?" Options: "Proceed anyway" | "Adjust approach" If "Proceed anyway": accept current plans and continue to step 13. If "Adjust approach": increment stall_reentry_count, open freeform discussion, then re-enter step 8 (full replanning). Note: re-entry resets iteration_count and prev_issue_count but stall_reentry_count persists across re-entries and is capped at 2.

If stall_reentry_count >= 2: Display: Stall persists after 2 re-planning attempts. The following issues could not be resolved automatically: List the remaining issues from the checker. Suggest: "Consider resolving these issues manually or running /gsd:debug to investigate root causes." Options: "Proceed anyway" | "Abandon" If "Proceed anyway": accept current plans and continue to step 13. If "Abandon": stop workflow.

12.5. Plan Bounce (Optional External Refinement)

Skip if: --skip-bounce flag, --gaps flag, or bounce is not activated.

Activation: Bounce runs when --bounce flag is present OR workflow.plan_bounce config is true. The --skip-bounce flag always wins (disables bounce even if config enables it). The --gaps flag also disables bounce (gap-closure mode should not modify plans externally).

Prerequisites: workflow.plan_bounce_script must be set to a valid script path. If bounce is activated but no script is configured, display warning and skip:

⚠ Plan bounce activated but no script configured.
Set workflow.plan_bounce_script to the path of your refinement script.
Skipping bounce step.

Read pass count:

BOUNCE_PASSES=$(gsd_run query config-get workflow.plan_bounce_passes 2>/dev/null || echo "2")
BOUNCE_SCRIPT=$(gsd_run query config-get workflow.plan_bounce_script 2>/dev/null | jq -r '.' 2>/dev/null || true)

Display banner:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 GSD ► BOUNCING PLANS (External Refinement)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Script: ${BOUNCE_SCRIPT}
Max passes: ${BOUNCE_PASSES}

For each PLAN.md file in the phase directory:

Backup: Copy *-PLAN.md to *-PLAN.pre-bounce.md

cp "${PLAN_FILE}" "${PLAN_FILE%.md}.pre-bounce.md"

Invoke bounce script:

"${BOUNCE_SCRIPT}" "${PLAN_FILE}" "${BOUNCE_PASSES}"

Validate bounced plan — YAML frontmatter integrity: After the script returns, check that the bounced file still has valid YAML frontmatter (opening and closing --- delimiters with parseable content between them). If the bounced plan breaks YAML frontmatter validation, restore the original from the pre-bounce.md backup and continue to the next plan:

⚠ Bounced plan ${PLAN_FILE} has broken YAML frontmatter — restoring original from pre-bounce backup.

Handle script failure: If the bounce script exits non-zero, restore the original plan from the pre-bounce.md backup and continue to the next plan:

⚠ Bounce script failed for ${PLAN_FILE} (exit code ${EXIT_CODE}) — restoring original from pre-bounce backup.

After all plans are bounced:

Re-run plan checker on bounced plans: Spawn gsd-plan-checker (same as step 10) on all modified plans. If a bounced plan fails the checker, restore original from its pre-bounce.md backup:

⚠ Bounced plan ${PLAN_FILE} failed checker validation — restoring original from pre-bounce backup.

Commit surviving bounced plans: If at least one plan survived both the frontmatter validation and the checker re-run, commit the changes:

gsd_run query commit "refactor(${padded_phase}): bounce plans through external refinement" --files "${PHASE_DIR}/*-PLAN.md"

Display summary:

Plan bounce complete: {survived}/{total} plans refined

Clean up: Remove all *-PLAN.pre-bounce.md backup files after the bounce step completes (whether plans survived or were restored).

13. Requirements Coverage Gate

After plans pass the checker (or checker is skipped), verify that all phase requirements are covered by at least one plan.

Skip if: phase_req_ids is null or TBD (no requirements mapped to this phase).

Step 1: Extract requirement IDs claimed by plans

# Collect all requirement IDs from plan frontmatter
PLAN_REQS=$(grep -h "requirements_addressed\|requirements:" ${PHASE_DIR}/*-PLAN.md 2>/dev/null | tr -d '[]' | tr ',' '\n' | sed 's/^[[:space:]]*//' | sort -u)

Step 2: Compare against phase requirements from ROADMAP

For each REQ-ID in phase_req_ids:

If REQ-ID appears in PLAN_REQS → covered ✓
If REQ-ID does NOT appear in any plan → uncovered ✗

Step 3: Check CONTEXT.md features against plan objectives

Read CONTEXT.md <decisions> section. Extract feature/capability names. Check each against plan <objective> blocks. Features not mentioned in any plan objective → potentially dropped.

Step 4: Report

If all requirements covered and no dropped features:

✓ Requirements coverage: {N}/{N} REQ-IDs covered by plans

→ Proceed to step 14.

If gaps found:

## ⚠ Requirements Coverage Gap

{M} of {N} phase requirements are not assigned to any plan:

| REQ-ID | Description | Plans |
|--------|-------------|-------|
| {id} | {from REQUIREMENTS.md} | None |

{K} CONTEXT.md features not found in plan objectives:
- {feature_name} — described in CONTEXT.md but no plan covers it

Options:
1. Re-plan to include missing requirements (recommended)
2. Move uncovered requirements to next phase
3. Proceed anyway — accept coverage gaps

If TEXT_MODE is true, present as a plain-text numbered list (options already shown in the block above). Otherwise use AskUserQuestion to present the options.

13a. Decision Coverage Gate

After the requirements coverage gate passes, verify that every trackable decision captured by discuss-phase in CONTEXT.md <decisions> is referenced by at least one plan. This is the translation gate from issue #2492 — its job is to refuse to mark a phase planned when a discuss-phase decision silently dropped on the way into the plans.

Skip if workflow.context_coverage_gate is explicitly set to false (absent key = enabled). Also skip if no CONTEXT.md exists for this phase (nothing to translate) or if its <decisions> block is empty.

GATE_CFG=$(gsd_run query config-get workflow.context_coverage_gate 2>/dev/null || echo "true")
if [ "$GATE_CFG" != "false" ]; then
  GATE_RESULT=$(gsd_run query check.decision-coverage-plan "${PHASE_DIR}" "${CONTEXT_PATH}")
  # BLOCKING: refuse to mark phase planned when a trackable decision is uncovered.
  # `passed: true` covers both real-pass and skipped cases (gate disabled / no CONTEXT.md /
  # no trackable decisions). Verify-phase counterpart deliberately omits this exit-1 — that
  # gate is non-blocking by design (review finding F15).
  echo "$GATE_RESULT" | jq -e '(.passed // .data.passed) == true' >/dev/null || {
    echo "$GATE_RESULT" | jq -r '(.message // .data.message // "Decision coverage gate failed.")'
    exit 1
  }
fi

The handler returns JSON:

{
  "passed": true,
  "skipped": false,
  "total":  2,
  "covered": 2,
  "uncovered": [ { "id": "D-01", "text": "...", "category": "..." } ],
  "message": "..."
}

If passed is true (or skipped is true): Display ✓ Decision coverage: {M}/{N} CONTEXT.md decisions covered by plans (or (skipped — gate disabled) / (skipped — no decisions)) and proceed to step 13b.

If passed is false: Display the handler's message block. It already names each uncovered decision (D-NN | category | text) and tells the user what to do — cite the id in a relevant plan's must_haves / truths, or move the decision under ### Claude's Discretion / tag it [informational] if it should not be tracked. Then offer:

Options:
1. Re-plan to cover missing decisions (recommended)
2. Edit CONTEXT.md to mark dropped decisions as [informational] / Discretion
3. Proceed anyway — accept the coverage gap

If TEXT_MODE is true, present as a plain-text numbered list. Otherwise use AskUserQuestion. Selecting "Proceed anyway" continues to step 13b but records the override in STATE.md so verify-phase can re-surface it.

Why this gate blocks: failing here is cheap. The plans are the contract between discuss-phase and execute-phase; if a decision isn't visible in any plan, no executor will implement it. Catching that now beats discovering it after thousands of dollars of execution.

13b. Record Planning Completion in STATE.md

After plans pass all gates, record that planning is complete so STATE.md reflects the new phase status:

gsd_run query state.planned-phase --phase "${PHASE_NUMBER}" --name "${PHASE_NAME}" --plans "${PLAN_COUNT}"

This updates STATUS to "Ready to execute", sets the correct plan count, and timestamps Last Activity.

13c. Annotate ROADMAP with Wave Dependencies and Cross-cutting Constraints

After plans are finalized, annotate the ROADMAP.md plan list for this phase with:

Wave dependency notes — a bold header before each wave group ("Wave 2 (blocked on Wave 1 completion)")
Cross-cutting constraints — a "Cross-cutting constraints:" subsection listing must_haves.truths entries that appear in 2 or more plans

This step is derived entirely from existing PLAN frontmatter — no extra LLM pass is required.

gsd_run query roadmap.annotate-dependencies "${PHASE_NUMBER}"

This operation is idempotent: if wave headers or cross-cutting constraints already exist in the ROADMAP phase section, the command returns without modifying the file. Skip this step if plan_count is 0.

13d. Commit Plans if commit_docs is true

If commit_docs is true (from the init JSON parsed in step 1), commit the generated plan artifacts (including any ROADMAP.md annotations from step 13c):

gsd_run query commit "docs(${PADDED_PHASE}): create phase plan" --files "${PHASE_DIR}"/*-PLAN.md .planning/STATE.md .planning/ROADMAP.md

This commits all PLAN.md files for the phase plus the updated STATE.md and ROADMAP.md to version-control the planning artifacts. Skip this step if commit_docs is false.

13e. Post-Planning Gap Analysis

After all plans are generated, committed, and the Requirements Coverage Gate (§13) has run, emit a single unified gap report covering both REQUIREMENTS.md and the CONTEXT.md <decisions> section. This is a proactive, post-hoc report — it does not block phase advancement and does not re-plan. It exists so that any requirement or decision that slipped through the per-plan checks is surfaced in one place before execution begins.

Skip if: workflow.post_planning_gaps is false. Default is true.

POST_PLANNING_GAPS=$(gsd_run query config-get workflow.post_planning_gaps --default true 2>/dev/null || echo true)
if [ "$POST_PLANNING_GAPS" = "true" ]; then
  # Scope to this phase's mapped REQ-IDs (#447); null/TBD skips the requirements comparison (CONTEXT.md decisions still reported), mirroring §13.
  gsd_run gap-analysis --phase-dir "${PHASE_DIR}" --phase-req-ids "$(gsd_run query init.plan-phase "$PHASE" --pick phase_req_ids 2>/dev/null || echo TBD)"
fi

(gsd-tools.cjs gap-analysis reads .planning/REQUIREMENTS.md, ${PHASE_DIR}/CONTEXT.md, and ${PHASE_DIR}/*-PLAN.md, then prints a markdown table with one row per REQ-ID and D-ID. Word-boundary matching prevents REQ-1 from being mistaken for REQ-10.)

Output format (deterministic; sorted REQUIREMENTS.md → CONTEXT.md, then natural sort within source):

## Post-Planning Gap Analysis

| Source | Item | Status |
|--------|------|--------|
| REQUIREMENTS.md | REQ-01 | ✓ Covered |
| REQUIREMENTS.md | REQ-02 | ✗ Not covered |
| CONTEXT.md | D-01 | ✓ Covered |
| CONTEXT.md | D-02 | ✗ Not covered |

⚠ N items not covered by any plan

Skip-gracefully behavior:

REQUIREMENTS.md missing → CONTEXT-only report.
CONTEXT.md missing → REQUIREMENTS-only report.
Both missing or <decisions> block missing → "No requirements or decisions to check" line, no error.

This step is non-blocking. If items are reported as not covered, the user may re-run /gsd:plan-phase --gaps to add plans, or proceed to execute-phase as-is.

14. Present Final Status

Route to <offer_next> OR auto_advance depending on flags/config.

15. Auto-Advance Check

Check for auto-advance trigger using values already loaded in step 1:

Parse --auto and --chain flags from $ARGUMENTS
Use auto_chain_active and auto_advance from the INIT JSON parsed in step 1 — do not issue additional config-get calls for these values (they are already present in the init output). Issuing redundant config-get calls for values already in INIT can cause infinite read loops on some runtimes.
Sync chain flag with intent — if user invoked manually (no --auto and no --chain), clear the ephemeral chain flag from any previous interrupted --auto chain. This does NOT touch workflow.auto_advance (the user's persistent settings preference):
```
if [[ ! "$ARGUMENTS" =~ --auto ]] && [[ ! "$ARGUMENTS" =~ --chain ]]; then
  gsd_run query config-set workflow._auto_chain_active false || true
fi
```

Set local variables from INIT (parsed once in step 1):

AUTO_CHAIN = auto_chain_active from INIT JSON (boolean, default false)
AUTO_CFG = auto_advance from INIT JSON (boolean, default false)

If --auto or --chain flag present AND AUTO_CHAIN is not true: Persist chain flag to config (handles direct invocation without prior discuss-phase):

if ([[ "$ARGUMENTS" =~ --auto ]] || [[ "$ARGUMENTS" =~ --chain ]]) && [[ "$AUTO_CHAIN" != "true" ]]; then
  gsd_run query config-set workflow._auto_chain_active true
fi

If --auto or --chain flag present OR AUTO_CHAIN is true OR AUTO_CFG is true:

Launch execute-phase using the Skill tool to avoid nested Task sessions (which cause runtime freezes due to deep agent nesting):
