msd-core/gsd-core/workflows/quick.md

Execute small, ad-hoc tasks with GSD guarantees (atomic commits, STATE.md tracking). Quick mode spawns gsd-planner (quick mode) + gsd-executor(s), tracks tasks in `.planning/quick/`, and updates STATE.md's "Quick Tasks Completed" table.

With --full flag: enables the complete quality pipeline — discussion + research + plan-checking + verification. One flag for everything.

With --validate flag: enables plan-checking (max 2 iterations) and post-execution verification only. Use when you want quality guarantees without discussion or research.

With --discuss flag: lightweight discussion phase before planning. Surfaces assumptions, clarifies gray areas, captures decisions in CONTEXT.md so the planner treats them as locked.

With --research flag: spawns a focused research agent before planning. Investigates implementation approaches, library options, and pitfalls. Use when you're unsure how to approach a task.

Granular flags are composable: --discuss --research --validate gives the same result as --full.

<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-planner — Creates detailed plans from phase scope
• gsd-plan-checker — Reviews plan quality before execution
• gsd-executor — Executes plan tasks, commits, creates SUMMARY.md
• gsd-verifier — Verifies phase completion, checks quality gates
• gsd-code-reviewer — Reviews source files for bugs, security issues, and code quality </available_agent_types>

**Step 1: Parse arguments and get task description**

Parse $ARGUMENTS for:

• --full flag → store $FULL_MODE=true, $DISCUSS_MODE=true, $RESEARCH_MODE=true, $VALIDATE_MODE=true
• --validate flag → store $VALIDATE_MODE=true
• --discuss flag → store $DISCUSS_MODE=true
• --research flag → store $RESEARCH_MODE=true
• Remaining text → use as $DESCRIPTION if non-empty

After parsing, normalize: if $DISCUSS_MODE and $RESEARCH_MODE and $VALIDATE_MODE are all true, set $FULL_MODE=true. This ensures --discuss --research --validate is treated identically to --full.

Parse JSON for: planner_model, executor_model, checker_model, verifier_model, reviewer_model, commit_docs, branch_name, quick_id, slug, date, timestamp, quick_dir, task_dir, roadmap_exists, planning_exists, response_language.

init.quick does not emit dedicated state_path/project_path fields, so derive them from the already-absolute quick_dir (#2376 — files handed to a spawned subagent must resolve regardless of that subagent's own cwd):

STATE_PATH="$(dirname "${quick_dir}")/STATE.md"
PROJECT_PATH="$(dirname "${quick_dir}")/PROJECT.md"

USE_WORKTREES=$(gsd_run query config-get workflow.use_worktrees --raw 2>/dev/null || echo "true")
RUNTIME=$(gsd_run query config-get runtime --default claude --raw 2>/dev/null || echo "claude")

Resolve isolation now (#2584/#2652). Read @gsd-core/references/dispatch-isolation-gate.md and run its Resolve ISOLATION, Single-agent dispatch sites, and Resolve the harness flag blocks in order; they set ISOLATION/HARNESS_FLAG via query dispatch-isolation. ISOLATION — not RUNTIME — gates every worktree decision below. Substitute {harnessFlag} in Step 6's Agent() with $HARNESS_FLAG+comma when ISOLATION = "harness-worktree", else empty. {harnessFlag} is a template placeholder, not a shell variable.

If USE_WORKTREES is not "false", run a startup orphan sweep before spawning any executors. This reaps locked worktrees whose lock-owner process is dead, whose branch is merged into the default branch, and whose lock file mtime is older than 5 minutes. Running it at startup prevents accumulation of orphaned worktrees from prior sessions that exited without cleanup (#3707).

if [ "$USE_WORKTREES" != "false" ]; then
  gsd_run query worktree.reap-orphans 2>/dev/null || true
fi

If the project uses git submodules, worktree isolation is unsafe only when the quick task touches a submodule path. The previous behavior unconditionally disabled worktree isolation whenever .gitmodules existed, which penalised every quick task in a submodule project even when the task was nowhere near a submodule. Parse submodule paths from .gitmodules so the executor can act on actual submodule paths rather than the mere file's existence:

# Parse submodule paths from .gitmodules once (empty if no .gitmodules).
# SUBMODULE_PATHS is a newline-separated list of repo-relative paths used as
# a fail-loud commit-time guard inside the quick-task executor — if the
# executor stages any path that falls inside SUBMODULE_PATHS, it must abort
# the commit and surface the conflict rather than silently corrupting the
# submodule state.
if [ -f .gitmodules ]; then
  SUBMODULE_PATHS=$(git config --file .gitmodules --get-regexp '^submodule\..*\.path$' 2>/dev/null | awk '{print $2}')
else
  SUBMODULE_PATHS=""
fi

Quick mode does not have a pre-declared files_modified list (the task is freeform), so use a fail-loud guard at commit time: when the executor stages files for the quick-task commit, if any staged path falls inside a SUBMODULE_PATHS entry, abort with a clear error explaining that worktree-isolated commits cannot safely span submodule boundaries — the user can re-run with workflow.use_worktrees=false to fall back to sequential execution on the main tree. If SUBMODULE_PATHS is empty (no .gitmodules in the repo), worktree isolation proceeds normally.

If roadmap_exists is false: Error — Quick mode requires an active project with ROADMAP.md. Run /gsd:new-project first.

Quick tasks can run mid-phase - validation only checks ROADMAP.md exists, not phase status.

---

Step 2.5: Handle quick-task branching

If branch_name is empty/null: Skip and continue on the current branch.

If branch_name is set: Check out the quick-task branch before any planning commits.

The new branch must fork off the project's default branch (origin/HEAD), not off whatever HEAD happens to be checked out — otherwise consecutive quick tasks compound on top of each other and stay unpushed (#2916). If $branch_name already exists locally, reuse it as-is so resumed work is not rebased.

DEFAULT_BRANCH=$(gsd_run query git.base-branch 2>/dev/null \
  || git symbolic-ref --quiet --short refs/remotes/origin/HEAD 2>/dev/null | sed 's|^origin/||' \
  || echo main)

if git show-ref --verify --quiet "refs/heads/$branch_name"; then
  git switch "$branch_name" \
    || { echo "ERROR: Could not switch to existing quick-task branch '$branch_name'." >&2; exit 1; }
else
  # Fetch the default branch so origin/$DEFAULT_BRANCH is current. If the fetch
  # fails (offline, no remote, auth failure) AND we have no local copy of
  # origin/$DEFAULT_BRANCH to fall back on, abort — creating the branch off
  # arbitrary HEAD is exactly the bug #2916 fixed.
  if ! git fetch --quiet origin "$DEFAULT_BRANCH"; then
    if ! git show-ref --verify --quiet "refs/remotes/origin/$DEFAULT_BRANCH"; then
      echo "ERROR: Could not fetch origin/$DEFAULT_BRANCH and no local copy exists. Refusing to create '$branch_name' off the current HEAD (#2916). Resolve the remote/network issue and retry." >&2
      exit 1
    fi
    echo "WARNING: git fetch origin $DEFAULT_BRANCH failed; using the local copy of origin/$DEFAULT_BRANCH as base." >&2
  fi

  if [ -n "$(git status --porcelain)" ]; then
    echo "WARNING: Uncommitted changes present. Carrying them onto the new quick-task branch — they will be branched off origin/$DEFAULT_BRANCH (not the previous-task HEAD)."
  else
    # Best-effort: fast-forward the local default branch so subsequent local
    # work sees the latest tip. Failure here is non-fatal because we always
    # create the new branch directly from origin/$DEFAULT_BRANCH below.
    git switch --quiet "$DEFAULT_BRANCH" 2>/dev/null \
      && git merge --ff-only --quiet "origin/$DEFAULT_BRANCH" 2>/dev/null \
      || true
  fi

  # Pin the new branch to origin/$DEFAULT_BRANCH so the start point is
  # deterministic regardless of which branch we are currently on (#2916).
  # On success HEAD is exactly at origin/$DEFAULT_BRANCH, so a post-creation
  # merge-base / "ahead-of" guard would be unreachable — the explicit base
  # argument here is the single source of correctness for #2916.
  # --no-track: with the default branch.autoSetupMerge=true, checkout -b from a
  # remote-tracking ref wires branch.<name>.merge to refs/heads/$DEFAULT_BRANCH
  # (origin/master), so a GUI sync pushes quick-task commits straight onto
  # origin/$DEFAULT_BRANCH, bypassing PR review (#2498).
  git checkout -b "$branch_name" "origin/$DEFAULT_BRANCH" --no-track \
    || { echo "ERROR: Could not create '$branch_name' from origin/$DEFAULT_BRANCH (#2916)." >&2; exit 1; }
fi

All quick-task commits for this run stay on that branch. User handles merge/rebase afterward.

Step 3: Create task directory

mkdir -p "${task_dir}"

---

Step 4: Create quick task directory

Create the directory for this quick task:

QUICK_DIR="${task_dir}"
mkdir -p "$QUICK_DIR"

Report to user:

Creating quick task ${quick_id}: ${DESCRIPTION}
Directory: ${QUICK_DIR}

Store $QUICK_DIR for use in orchestration.

Step 5: Spawn planner (quick mode)

If $VALIDATE_MODE: Use quick-full mode with stricter constraints.

If NOT $VALIDATE_MODE: Use standard quick mode.

ORCHESTRATOR RULE — CODEX RUNTIME: After calling Agent() above, stop working on this task immediately. Do not read more files, edit code, or run tests related to this task while the subagent is active. Wait for the subagent to return its result. This prevents duplicate work, conflicting edits, and wasted context. Only resume when the subagent result is available.

After planner returns:

1. Verify plan exists at ${QUICK_DIR}/${quick_id}-PLAN.md
2. Extract plan count (typically 1 for quick tasks)
3. Report: "Plan created: ${QUICK_DIR}/${quick_id}-PLAN.md"

If plan not found, error: "Planner failed to create ${quick_id}-PLAN.md"

Step 6: Spawn executor

Auto-degrade to sequential if HEAD has diverged from the worktree fork base (#1941, mirrors execute-phase's #683/#1369 guard). Claude Code's isolation="worktree" forks new worktrees from origin/HEAD, not the live local HEAD. If a prior quick task in this session (or the Step 5.6 pre-dispatch plan commit above) advanced local HEAD without an intervening git push, origin/HEAD stays pinned to a stale ancestor and the executor's worktree_branch_check guard halts with a base-mismatch fatal — potentially many commits behind, not just one. Run this check immediately before capturing EXPECTED_BASE so it reflects the most current local state.

if [ "$ISOLATION" = "harness-worktree" ] && [ "${USE_WORKTREES:-true}" != "false" ]; then
  _QUICK_SHOULD_DEGRADE=$(gsd_run query worktree.base-check --pick shouldDegrade 2>/dev/null || true)
  if [ "$_QUICK_SHOULD_DEGRADE" = "true" ]; then
    _QUICK_DEGRADE_MSG=$(gsd_run query worktree.base-check --pick message 2>/dev/null || true)
    [ -n "$_QUICK_DEGRADE_MSG" ] && printf '%s\n' "$_QUICK_DEGRADE_MSG" >&2
    echo "⚠ [#1941] Worktree fork base diverged from orchestrator HEAD — auto-degrading to sequential mode for this quick task to avoid a base-mismatch halt." >&2
    USE_WORKTREES=false
    ISOLATION=none
  fi
fi

# Re-resolve (and, as a side effect, re-persist) now that the base-check
# auto-degrade above may have changed $ISOLATION since the Step 2 gate's
# `dispatch-isolation` call (#3045). That first call recorded the NATURALLY
# resolved mode into the run-scoped sentinel the isolation guard hooks read
# (hooks/gsd-agent-isolation-guard.js, hooks/gsd-cursor-subagent-start.js via
# hooks/lib/isolation-sentinel.js). The degrade above is decided HERE, in
# shell — the resolver cannot see it — so without this the sentinel still
# asserts `harness-worktree` while the dispatch below correctly omits the
# harness flag, and the guard denies the dispatch with exit 2. `--force-isolation`
# pushes the FINAL, shell-computed value through that SAME single write path
# (`none` also clears the stored harnessFlag, since none applies to sequential
# dispatch). Best-effort: a write failure here must never fail the task — the
# guards' own sentinel-absent fallback is safe, just less precise.
gsd_run query dispatch-isolation --raw --force-isolation "$ISOLATION" >/dev/null 2>&1 || true

Capture current HEAD before spawning (used for worktree branch check):

EXPECTED_BASE=$(git rev-parse HEAD)
if [ "$ISOLATION" = "harness-worktree" ]; then   # keyed on ISOLATION like every other dispatch-coupled branch (#2652)
  # BSD/macOS mktemp only randomizes XXXXXX when it is the final path component, so make a
  # suffixless temp then append the extension — portable across BSD + GNU (#1520).
  QUICK_WORKTREE_MANIFEST=$(mktemp "${TMPDIR:-/tmp}/gsd-quick-worktree-XXXXXX") && mv "$QUICK_WORKTREE_MANIFEST" "${QUICK_WORKTREE_MANIFEST}.json" && QUICK_WORKTREE_MANIFEST="${QUICK_WORKTREE_MANIFEST}.json" || exit 1
  printf '{"worktrees":[]}\n' > "$QUICK_WORKTREE_MANIFEST"
  export QUICK_WORKTREE_MANIFEST
fi

Spawn gsd-executor with plan reference:

Agent(
  prompt="
Execute quick task ${quick_id}.

${ISOLATION === "harness-worktree" ? `
<worktree_branch_check>
ORCHESTRATOR build-time embed (NOT a sub-agent runtime step): before this dispatch, read \`gsd-core/references/worktree-branch-check.md\`, substitute \`{EXPECTED_BASE}\` with the base SHA captured above (${EXPECTED_BASE}), substitute \`{EXPECTED_BASE_ALTERNATE}\` with \`${QUICK_PLAN_PARENT}\` when it differs from \`${EXPECTED_BASE}\` (otherwise empty), and replace this note with that fragment's \`<worktree_branch_check>\` block so the dispatched prompt carries the runnable guard verbatim — do not pass this instruction through in its place.
</worktree_branch_check>

FIRST ACTION after the worktree branch check: ensure the quick PLAN.md exists at a worktree-rooted relative path before any Read/Edit/Write path can be primed. If \`${QUICK_DIR}/${quick_id}-PLAN.md\` is absent, materialize it from the shared git object store:

\`\`\`bash
QUICK_PLAN_COMMIT="${QUICK_PLAN_COMMIT}"
QUICK_PLAN_PATH="${QUICK_DIR}/${quick_id}-PLAN.md"
if [ ! -f "$QUICK_PLAN_PATH" ]; then
  mkdir -p "$(dirname "$QUICK_PLAN_PATH")"
  git show "${QUICK_PLAN_COMMIT}:${QUICK_PLAN_PATH}" > "$QUICK_PLAN_PATH" || {
    echo "FATAL: unable to materialize quick plan from ${QUICK_PLAN_COMMIT}:${QUICK_PLAN_PATH}; refusing to continue." >&2
    exit 42
  }
fi
\`\`\`
` : ''}

- ${STATE_PATH} (Project state)
- ./CLAUDE.md or ./.claude/CLAUDE.md (Project instructions, if exists)

</files_to_read>

${AGENT_SKILLS_EXECUTOR}

<submodule_commit_guard>
SUBMODULE_PATHS for this project: ${SUBMODULE_PATHS}

If SUBMODULE_PATHS is non-empty, you MUST run this fail-loud guard immediately
before EVERY git commit you create during this quick task (after \`git add\`,
before \`git commit\`). Quick mode does not have a pre-declared files_modified
list, so the guard runs at commit time:

ORCHESTRATOR RULE — CODEX RUNTIME: After calling Agent() above, stop working on this task immediately. Do not read more files, edit code, or run tests related to this task while the subagent is active. Wait for the subagent to return its result. This prevents duplicate work, conflicting edits, and wasted context. Only resume when the subagent result is available.

If the executor ran isolated (ISOLATION = "harness-worktree" at dispatch), append its returned {agent_id, worktree_path, branch, expected_base, allowed_bases} metadata to QUICK_WORKTREE_MANIFEST before cleanup. Set expected_base to ${EXPECTED_BASE} and allowed_bases to ["${EXPECTED_BASE}", "${QUICK_PLAN_PARENT}"] with duplicates removed. If any required field is unavailable, stop and ask for recovery; do not discover global worktrees.

After executor returns:

1. Worktree cleanup: If the executor ran isolated (ISOLATION = "harness-worktree" at dispatch), merge the worktree branch back and clean up:

   QUICK_WORKTREE_MANIFEST=${QUICK_WORKTREE_MANIFEST:-$WAVE_WORKTREE_MANIFEST}
   [ -n "${QUICK_WORKTREE_MANIFEST:-}" ] && [ -f "$QUICK_WORKTREE_MANIFEST" ] || {
     echo "BLOCKED: missing QUICK_WORKTREE_MANIFEST; refusing broad worktree cleanup (#3384)." >&2
     exit 1
   }
   
   # Prefer the bounded cleanup helper. It verifies branch identity, expected
   # base, deletion diffs, merge result, and worktree removal before branch
   # deletion. If it blocks, resolve the reported manifest entry and rerun.
   # Fail closed: SDK refusal (safety guard #3174/#3384) must surface — do not swallow exit 1.
   gsd_run query worktree.cleanup-wave --manifest "$QUICK_WORKTREE_MANIFEST" || exit 1
   

   If ISOLATION was not "harness-worktree" at dispatch (including a #1941 base-check degrade — that is this file's degrade; #2649 is the diagnose-issues.md / execute-plan.md one), skip this step.

   ISOLATED-RUN RECOVERY — FAIL SAFE (#1292): When an isolated (worktree) run is rejected — the user declines to merge it, the orchestrator surfaces recovery guidance for a blocked/halted plan, or the run over-reached the requested scope — the worktree-isolation contract MUST hold through recovery. Do NOT propose continuing on main/the primary checkout as the default or recommended recovery path. Default to a safe halt and offer: (a) re-attempt in a fresh, narrowly-scoped worktree, or (b) inspect or discard the rejected worktree without merging. Any path that edits the primary checkout requires an explicit, clearly-labeled confirmation from the user first — editing main directly is never the proposed or default option for a run the user configured to be isolated.

2. Verify summary exists at ${QUICK_DIR}/${quick_id}-SUMMARY.md

3. Extract commit hash from executor output

4. Report completion status

Known Claude Code bug (classifyHandoffIfNeeded): If executor reports "failed" with error classifyHandoffIfNeeded is not defined, this is a Claude Code runtime bug — not a real failure. Check if summary file exists and git log shows commits. If so, treat as successful.

If summary not found, error: "Executor failed to create ${quick_id}-SUMMARY.md"

Note: For quick tasks producing multiple plans (rare), spawn executors in parallel waves per execute-phase patterns.

Step 6.25: Code review (auto)

Skip this step entirely if $FULL_MODE is false.

Capability gate:

EXECUTE_POST_HOOKS_JSON=$(gsd_run loop render-hooks execute:post --raw)

Resolve active step hooks from EXECUTE_POST_HOOKS_JSON where kind == "step" and ref.skill == "code-review".

If no active code-review step hook exists, skip with message "Code review skipped (code-review capability inactive)".

Scope files from executor's commits:

# Find the diff base: last commit before quick task started
# Use git log to find commits referencing the quick task id, then take the parent of the oldest
QUICK_COMMITS=$(git log --oneline --format="%H" --grep="${quick_id}" 2>/dev/null)
if [ -n "$QUICK_COMMITS" ]; then
  DIFF_BASE=$(echo "$QUICK_COMMITS" | tail -1)^
  # Verify parent exists (guard against first commit in repo)
  git rev-parse "${DIFF_BASE}" >/dev/null 2>&1 || DIFF_BASE=$(echo "$QUICK_COMMITS" | tail -1)
else
  # No commits found for this quick task — skip review
  DIFF_BASE=""
fi

if [ -n "$DIFF_BASE" ]; then
  CHANGED_FILES=$(git diff --name-only "${DIFF_BASE}..HEAD" -- . ':!.planning' 2>/dev/null | tr '\n' ' ')
else
  CHANGED_FILES=""
fi

If CHANGED_FILES is empty, skip with "No source files changed — skipping code review."

Invoke review:

Agent(
  prompt="Review these files for bugs, security issues, and code quality.
  Files: ${CHANGED_FILES}
  Output: ${QUICK_DIR}/${quick_id}-REVIEW.md
  Depth: quick",
  subagent_type="gsd-code-reviewer",
  model="{reviewer_model}"
)

ORCHESTRATOR RULE — CODEX RUNTIME: After calling Agent() above, stop working on this task immediately. Do not read more files, edit code, or run tests related to this task while the subagent is active. Wait for the subagent to return its result. This prevents duplicate work, conflicting edits, and wasted context. Only resume when the subagent result is available.

If review produces findings, display advisory message. Error handling: Failures are non-blocking — catch and proceed.

---

If section_manifest is null or "quick-verification" is in its included list: read and execute gsd-core/workflows/quick/steps/quick-verification.md. Otherwise skip — do not read the file.

---

Step 7: Update STATE.md

Update STATE.md with quick task completion record.

7a. Check if "Quick Tasks Completed" section exists:

Read STATE.md and check for ### Quick Tasks Completed section.

7b. If section doesn't exist, create it:

Insert after ### Blockers/Concerns section:

If $VALIDATE_MODE:

### Quick Tasks Completed

| # | Description | Date | Commit | Status | Directory |
|---|-------------|------|--------|--------|-----------|

If NOT $VALIDATE_MODE:

### Quick Tasks Completed

| # | Description | Date | Commit | Directory |
|---|-------------|------|--------|-----------|

Note: If the table already exists, match its existing column format. If adding --validate (or --full) to a project that already has quick tasks without a Status column, add the Status column to the header and separator rows, and leave Status empty for the new row's predecessors.

7c. Append new row to table:

Use date from init:

If $VALIDATE_MODE (or table has Status column):

| ${quick_id} | ${DESCRIPTION} | ${date} | ${commit_hash} | ${VERIFICATION_STATUS} | [${quick_id}-${slug}](./quick/${quick_id}-${slug}/) |

If NOT $VALIDATE_MODE (and table has no Status column):

| ${quick_id} | ${DESCRIPTION} | ${date} | ${commit_hash} | [${quick_id}-${slug}](./quick/${quick_id}-${slug}/) |

For a schema-safe append outside this workflow (e.g. from fast.md), gsd_run quick-tasks-append --task <text> performs the equivalent write via the shared, schema-backed appendQuickTaskRow helper (#2133, ADR-2143 §3/§7).

7d. Update "Last activity" line:

Use date from init:

Last activity: ${date} - Completed quick task ${quick_id}: ${DESCRIPTION}

Use Edit tool to make these changes atomically

---

Step 8: Final commit and completion

Stage and commit quick task artifacts. This step MUST always run — even if the executor already committed some files (e.g. when running without worktree isolation). The gsd-tools.cjs query commit command (or legacy gsd-tools.cjs commit) handles already-committed files gracefully.

Build file list:

• ${QUICK_DIR}/${quick_id}-PLAN.md
• ${QUICK_DIR}/${quick_id}-SUMMARY.md
• .planning/STATE.md
• If $DISCUSS_MODE and context file exists: ${QUICK_DIR}/${quick_id}-CONTEXT.md
• If $RESEARCH_MODE and research file exists: ${QUICK_DIR}/${quick_id}-RESEARCH.md
• If $VALIDATE_MODE and verification file exists: ${QUICK_DIR}/${quick_id}-VERIFICATION.md
• If ${QUICK_DIR}/${quick_id}-deferred-items.md exists: ${QUICK_DIR}/${quick_id}-deferred-items.md

# Explicitly stage all artifacts before commit — PLAN.md may be untracked
# if the executor ran without worktree isolation and committed docs early
# Filter .planning/ files from staging if commit_docs is disabled (#1783)
COMMIT_DOCS=$(gsd_run query config-get commit_docs 2>/dev/null || echo "true")
if [ "$COMMIT_DOCS" = "false" ]; then
  file_list_filtered=$(echo "${file_list}" | tr ' ' '\n' | grep -v '^\.planning/' | tr '\n' ' ')
  git add ${file_list_filtered} 2>/dev/null
else
  git add ${file_list} 2>/dev/null
fi
gsd_run query commit "docs(quick-${quick_id}): ${DESCRIPTION}" --files ${file_list}

Get final commit hash:

commit_hash=$(git rev-parse --short HEAD)

Display completion output:

If $VALIDATE_MODE:

---

GSD > QUICK TASK COMPLETE (VALIDATED)

Quick Task ${quick_id}: ${DESCRIPTION}

${RESEARCH_MODE ? 'Research: ' + QUICK_DIR + '/' + quick_id + '-RESEARCH.md' : ''}
Summary: ${QUICK_DIR}/${quick_id}-SUMMARY.md
Verification: ${QUICK_DIR}/${quick_id}-VERIFICATION.md (${VERIFICATION_STATUS})
Commit: ${commit_hash}

---

Ready for next task: /gsd:quick ${GSD_WS}

If NOT $VALIDATE_MODE:

---

GSD > QUICK TASK COMPLETE

Quick Task ${quick_id}: ${DESCRIPTION}

${RESEARCH_MODE ? 'Research: ' + QUICK_DIR + '/' + quick_id + '-RESEARCH.md' : ''}
Summary: ${QUICK_DIR}/${quick_id}-SUMMARY.md
Commit: ${commit_hash}

---

Ready for next task: /gsd:quick ${GSD_WS}
