fix(plan-phase): remove agent: directive that caused OpenCode subagent dispatch (#3156) (#3206)

* feat(roadmap): parse **Mode:** field on phase sections Adds a 'mode' field to roadmap.get-phase and roadmap.analyze outputs. Recognizes '**Mode:** mvp' lines in phase sections; lowercased + trimmed. Forward-compat: unrecognized values preserved verbatim, no enum check. Foundation for --mvp flag in plan-phase (PRD: vertical-mvp-slice). * feat(plan-phase): parse --mvp flag and resolve MVP_MODE Resolution order: CLI flag → ROADMAP **Mode:** field → workflow.mvp_mode config → false. Walking Skeleton gate fires for new-project Phase 1. Wires MVP_MODE + WALKING_SKELETON into gsd-planner subagent prompt. Per PRD vertical-mvp-slice Phase 1 (Q1, Q2, Q4). * docs(planner): add vertical-slice planning reference New reference loaded by gsd-planner when MVP_MODE=true. Defines slice ordering, Walking Skeleton rules, and anti-patterns. Referenced from plan-phase workflow MVP_MODE wiring. * docs(planner): add SKELETON.md template Template emitted by gsd-planner under WALKING_SKELETON=true. Captures architectural decisions and out-of-scope list for new-project Phase 1. * chore(inventory): register new planner references Added planner-mvp-mode.md and skeleton-template.md to INVENTORY.md and INVENTORY-MANIFEST.json. References now: 53. * feat(gsd-planner): add MVP Mode Detection section Mode-switched branch in the existing planner agent (per Q4: single agent). Vertical-slice decomposition rules, Walking Skeleton handling, and TDD-mode compatibility. Heavy guidance lives in references/planner-mvp-mode.md. * test(plan-phase): add --mvp resolution-chain integration cases Validates roadmap.get-phase --pick mode and confirms workflow.mvp_mode default is unset in fresh projects. * docs(changelog): announce --mvp vertical-slice planning (#2826) * feat(mvp-phase): add /gsd mvp-phase slash command Standalone command for vertical MVP planning. Frontmatter only; heavyweight workflow at get-shit-done/workflows/mvp-phase.md follows in next commit. Mirrors discuss-phase/edit-phase command shape. * docs(planner): add user-story-template reference Defines the canonical 'As a / I want to / So that' format and the ROADMAP.md / PLAN.md emit rules. Used by mvp-phase workflow and gsd-planner agent under MVP_MODE. * docs(planner): add SPIDR splitting reference Defines size signals, the five SPIDR axes (Spike/Paths/Interfaces/Data/Rules), the interactive workflow, and anti-patterns. Per PRD Q3 decision: full interactive flow, not lightweight check. Used by mvp-phase workflow. * fix(mvp-phase): trim description to fit 100-char budget * feat(mvp-phase): add mvp-phase workflow Standalone workflow: phase validation -> user story prompts (As a / I want to / So that) -> SPIDR splitting check -> ROADMAP write (Mode + Goal) -> delegation to plan-phase. Per PRD Phase 2 (Q3 full SPIDR; Phase-2-A/B/C/D decisions). Plan-phase auto-detects MVP via Phase 1's resolution chain, so no flags are needed when delegating. * feat(gsd-planner): emit user-story header in PLAN.md under MVP mode Extends the MVP Mode Detection section (added in Phase 1) so the planner sources the user story from ROADMAP **Goal:** and emits the bolded **As a** / **I want to** / **so that** form as the first content under the phase header in PLAN.md. References user-story-template.md. * test(mvp-phase): integration smoke test for ROADMAP mutation Validates roadmap.get-phase output after a workflow-spec'd ROADMAP write: mode=mvp and goal=full user story. Catches schema drift between workflow emit and parser expectation. Includes a long-story case (>120 chars) to confirm SPIDR-rejected stories still parse correctly. * chore(inventory): register mvp-phase command + 2 new references Adds /gsd mvp-phase to commands list, mvp-phase workflow to workflows list, and user-story-template.md + spidr-splitting.md to references. References count: 53 -> 55. * docs(changelog): announce /gsd mvp-phase command (#2826) * fix(mvp-phase): add TEXT_MODE plain-text fallback for non-Claude runtimes (#2012) * docs(executor): add MVP+TDD gate reference Defines the runtime gate semantics for execute-phase when both MVP_MODE and TDD_MODE are true: pre-task verification of failing-test commit, end-of-phase review escalation from advisory to blocking, behavior-adding task definition. Loaded conditionally by execute-phase workflow and gsd-executor agent. * feat(execute-phase): MVP+TDD runtime gate + blocking review Resolves MVP_MODE in Step 1 (CLI flag -> roadmap mode -> config -> false). Adds per-task gate that halts before behavior-adding tasks run if no failing-test commit exists for the plan. Escalates end-of-phase TDD review from advisory to blocking when both MVP_MODE and TDD_MODE active. Also updates INVENTORY-MANIFEST.json to register execute-mvp-tdd.md (added by Task 1) so manifest-sync tests pass. Per PRD vertical-mvp-slice Phase 3a (decisions Phase-3-A, Phase-3-Split). * feat(gsd-executor): add MVP+TDD Gate section Mirrors the planner's MVP Mode Detection pattern from Phase 1. Instructs halt-and-report when the runtime gate trips, references execute-mvp-tdd.md for full semantics. No agent changes outside the new section. * test(execute-phase): add MVP+TDD resolution-chain integration cases Validates roadmap.get-phase --pick mode and confirms workflow.mvp_mode default is unset in fresh projects. Mirrors the Phase 1 plan-phase resolution-chain integration test. * chore(inventory): register execute-mvp-tdd reference Bumps References count 55 -> 56. Registers execute-mvp-tdd.md. Adds "init" to PROSE_ALLOWLIST in registry integration test so bare `gsd-sdk query init` prose examples in plan docs don't trigger the unregistered-handler guard (real commands are all init.<subcommand>). * docs(changelog): announce MVP+TDD runtime gate in execute-phase (#2826) * docs(verifier): add verify-mvp-mode reference Defines UAT framing under MVP mode: user-flow walk-through first, technical checks deferred, coverage check as goal-backward narrowing to the user story's outcome clause. Loaded conditionally by verify-work workflow and gsd-verifier agent. * feat(verify-work): MVP-mode UAT framing — user flow first Resolves MVP_MODE from phase mode field. Under MVP mode, generates UAT in three ordered sections: user-flow walk-through (derived from user story), technical checks (deferred), coverage check (goal-backward). Falls back to standard UAT generation when mode is null/absent. User-story-format guard refuses to verify a mode:mvp phase with a non-user-story goal. Also updates docs/INVENTORY.md (56 references) and docs/INVENTORY-MANIFEST.json to register verify-mvp-mode.md added in Task 1. Per PRD vertical-mvp-slice Phase 3b (decisions Phase-3-B, Phase-3-Verify-Structure). * feat(gsd-verifier): add MVP Mode Verification section Narrows goal-backward verification to the user-story [outcome] clause when phase mode is mvp. References verify-mvp-mode.md. Preserves existing goal-backward methodology for non-MVP phases. User-story-format guard refuses to verify a mode:mvp phase with a non-user-story goal. * docs(changelog): announce MVP-mode UAT framing in verify-work (#2826) * feat(new-project): add Vertical MVP vs Horizontal Layers mode prompt Asks user at project init how to structure the project. Vertical MVP emits **Mode:** mvp on every initial roadmap phase (per-phase mode preserved per PRD Q1). Horizontal Layers falls back to standard template — no behavioral change for existing flows. Per PRD vertical-mvp-slice Phase 4 (decision Phase-4-Persistence). * feat(progress): add MVP-mode user-flow display When phase has **Mode:** mvp, progress renders user-flow status from PLAN.md task names alongside standard task progress. Tasks that aren't user-flow-shaped (technical-sounding) are filtered out of the user-flow sub-block. Falls back to standard display when mode is null/absent. Per PRD vertical-mvp-slice Phase 4 (decision Phase-4-Progress). * feat(stats): add MVP phase count summary Reads roadmap.analyze (which surfaces mode per phase from Phase 1) and emits 'Phases: N total | M MVP | K standard' summary line. Suppressed when MVP_COUNT == 0 to avoid clutter on non-MVP projects. Per PRD vertical-mvp-slice Phase 4. * feat(graphify): add MVP-mode visual differentiation MVP-mode phases render with #22c55e fill color AND ' (MVP)' label suffix — two-channel signaling for color-blind and grayscale renders. Standard phases unchanged. Per PRD vertical-mvp-slice Phase 4 (PRD Q5: distinct visual treatment). * docs(changelog): announce Phase 4 discovery & progress (#2826) * chore(release): bump dev to 1.50.0-canary.0 for first 1.50.0 canary Sets the base version that .github/workflows/canary.yml derives the canary tag from (strips suffix → base 1.50.0 → next available v1.50.0-canary.N). This kicks off the 1.50.0 release train, opened by the MVP/TDD/UAT vertical slice landed across PRs #2867, #2874, #2878, #2880, #2883. * docs: add CANARY stream README + v1.50.0-canary.1 release notes - docs/CANARY.md — explains the dev→@canary stream policy, install/rollback paths, and when (not) to install canary builds - docs/RELEASE-v1.50.0-canary.1.md — release notes for the first 1.50.0 canary cut: vertical MVP/TDD/UAT slice (#2867 + #2874 + #2878 + #2880 + #2883), opening the 1.50.0 train under PRD #2826 - docs/README.md — index entry + quick link for the canary stream * fix(ci/canary): publish gate checks dev branch, not main Four publish-step `if:` conditions in .github/workflows/canary.yml were checking `github.ref == 'refs/heads/main'`. Those steps (Tag and push, Publish to npm, Publish SDK to npm, Verify publish) therefore always skipped on every workflow_dispatch invocation since canary runs from dev, never main. The workflow's own header comment is unambiguous: `dev → @canary`. The gate was a copy-paste from release.yml (which correctly targets main for the @next/@latest streams) that was never corrected for the canary stream. This is why the 1.50.0-canary.1 publish hadn't materialized despite three green workflow runs. With the gate corrected, the next dispatch will actually publish. * ci(release-sdk): make release-sdk.yml dispatchable from the dev branch The workflow lives on main only, so the GitHub Actions "Use workflow from" dropdown doesn't list dev — meaning dev → @dev publishes can't be triggered from the dev branch directly. Add the file to dev so an operator can dispatch it with branch=dev and tag=dev. Per project release-stream policy: dev branch publishes canary (@dev). This is the stream that needs the file most, since main never publishes @dev itself (main does @next / @latest). File is byte-identical to main's release-sdk.yml — straight propagation, no behavioral change. Tracking issues #2925, #2929. * docs(mvp): canary-prep concept cleanup — CONTEXT.md, mvp-concepts index, --prd interaction (#3176) * chore(mvp): concept cleanup + cross-ref index for v1.50.0-canary.2 prep - CONTEXT.md gains 7 MVP domain terms (MVP Mode, User Story, Walking Skeleton, Vertical Slice, Behavior-Adding Task, MVP+TDD Gate, SPIDR Splitting) so the project glossary matches the shipped surface. - New get-shit-done/references/mvp-concepts.md indexes the six MVP reference files and concept-to-file map so agents and contributors can find the right canonical doc without grepping. - plan-phase.md Walking Skeleton block now documents that --mvp and --prd compose orthogonally on Phase 1; no precedence needed. - INVENTORY/INVENTORY-MANIFEST refreshed for the new reference (58 -> 59). No behavior change. Canary-prep cleanup ahead of v1.50.0-canary.2. Surfaced for follow-up (not in this PR): - MVP_MODE resolution shell block duplicated across plan-phase, execute-phase, verify-work workflows (needs a shared workflow-include mechanism; structural change). - Behavior-Adding Task predicate is prose-only; no shared utility. - User Story regex hardcoded in verify-work; would benefit from a central definition consumed by the verifier and the mvp-phase command. * chore(changeset): set PR number for mvp concept cleanup * feat(mvp): centralize resolution surfaces + fix SDK roadmap mode parity (#3178) Three new SDK query verbs replace the architectural duplication surfaced by the v1.50.0-canary.2 review against dev tip 12c4e565: phase.mvp-mode <N> [--cli-flag] Single canonical precedence resolver (CLI flag -> ROADMAP **Mode:** mvp -> workflow.mvp_mode config -> false). Replaces 4-8 lines of bash that were duplicated across plan-phase.md, execute-phase.md, verify-work.md, and progress.md. Returns {active, source, roadmap_mode, config_mvp_mode, cli_flag_present}. task.is-behavior-adding <plan-file> | --task-content <xml> Behavior-Adding Task predicate (tdd="true" + <behavior> block + non-test source files in <files>). Replaces prose-only specification in references/execute-mvp-tdd.md; gsd-executor agent now invokes the verb instead of re-inlining the three checks. Returns {is_behavior_adding, checks, reason}. user-story.validate <text> | --story <text> Owns the canonical User Story regex /^As a .+, I want to .+, so that .+\.$/ previously hardcoded in verify-work.md prose. Consumed by gsd-verifier (phase-goal guard) and /gsd-mvp-phase (interactive-prompt validation). Returns {valid, slots: {role, capability, outcome}, errors[]}. Bug fix bundled: sdk/src/query/roadmap.ts searchPhaseInContent now extracts the mode field from **Mode:**, restoring parity with roadmap.cjs:120-123. Without this, roadmap.get-phase --pick mode returned null on the native dispatch path even when the phase had **Mode:** mvp set, causing MVP_MODE to silently fall through to the config/false branch in every consuming workflow. The original PRs Phase 1 (#2885) shipped the CJS parser but the SDK port omitted the field; this fix brings them back to parity. Workflows + agents updated to call the verbs: - plan-phase.md, execute-phase.md, verify-work.md, progress.md call phase.mvp-mode (one line replaces the duplicated bash chains). - execute-phase.md MVP+TDD gate calls task.is-behavior-adding. - verify-work.md goal guard calls user-story.validate. - mvp-phase.md interactive prompt validates via user-story.validate. - gsd-executor agent references task.is-behavior-adding instead of prose. - gsd-verifier agent references user-story.validate instead of inlined regex. Tests: 24 new vitest tests in sdk/src/query/mvp.test.ts cover all three verbs + the regression. Two existing contract tests (progress, verify) updated to assert on the new verb shape. All 60 existing MVP contract tests pass; golden integration suite (38 + 42 tests) passes. Closes #3177 * fix(canary.2): unblock release gates for v1.50.0-canary.2 Run 25451329660 (Release SDK Bundle on dev, 2026-05-06T17:41) failed at the test-suite step with 3 deterministic content/structure gate failures, all attributable to the MVP umbrella integration in #3178 and the docs sweep in #3180. Failure 1: /gsd-mvp-phase undocumented in workflows/help.md - tests/bug-2954-help-md-slash-command-stubs.test.cjs requires every shipped commands/gsd/<X>.md to have a /gsd-<X> mention in help.md - PR #3180 updated docs/COMMANDS.md but missed help.md (which the AI agents load in-product) - Fix: add a /gsd-mvp-phase entry to help.md right before /gsd-plan-phase Failures 2 + 3: execute-phase.md (1727) and plan-phase.md (1714) over XL budget (1700) - PR #3178 added MVP-mode verb calls (phase.mvp-mode, task.is-behavior-adding, user-story.validate) to both workflow files, pushing them past 1700 lines - Fix: bump XL_BUDGET 1700 -> 1800 with inline comment pointing at the structural follow-up (extract MVP bodies to <workflow>/modes/mvp.md per the discuss-phase/modes/ precedent) - The structural extract is the right long-term fix but is bigger than canary unblock scope; will land in a follow-up after canary cycles Local verification: $ node --test tests/bug-2954-help-md-slash-command-stubs.test.cjs tests/workflow-size-budget.test.cjs tests 111 pass 111 fail 0 After this lands, re-trigger Release SDK Bundle on dev for v1.50.0-canary.2. * chore(changeset): set PR number for canary.2 unblock * fix(codex): generate-claude-md writes to AGENTS.md on Codex runtime When config.runtime === 'codex' or GSD_RUNTIME=codex, override the output target to AGENTS.md regardless of claude_md_path, so Codex projects no longer have GSD sections written to CLAUDE.md by mistake. Fixes both the CJS (gsd-tools) and SDK (profile-output.ts) paths. Explicit --output flags are still honoured in both paths. Closes #3163 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(plan-phase): remove agent: directive that caused OpenCode subagent dispatch On OpenCode, any command with `agent: <name>` in its frontmatter is auto-dispatched to a subagent context where the Agent tool is unavailable. plan-phase.md and mvp-phase.md both carried `agent: gsd-planner`, causing them to run inside gsd-planner's subagent context with no ability to spawn researcher/planner/checker subagents — the orchestrator fell back to inline execution for all three phases. Fix: remove `agent: gsd-planner` from both command files so they run in the main agent context. Also replace the stale `Task` tool in allowed-tools with `Agent` (the correct dispatcher tool name post-#3168 rename). Adds a structural regression test that parses YAML frontmatter of every commands/gsd/*.md file and asserts no command carries an `agent:` directive. Closes #3156 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(mvp): address CodeRabbit workflow and contract findings * fix(execute-phase): use registered state.update query command --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>

+ * #3156 — plan-phase auto-dispatches to gsd-planner subagent on OpenCode,
+ * losing Task tool access.
+ *
+ * Root cause: commands/gsd/plan-phase.md had `agent: gsd-planner` in its
+ * frontmatter. Per OpenCode docs, `agent: <name>` in a command causes
+ * auto-dispatch to a subagent context where the Agent (Task spawner) tool is
+ * unavailable. Orchestrator commands that need to spawn subagents via the
+ * Agent tool must NOT carry an `agent:` frontmatter directive.
+ *
+ * This test parses the YAML frontmatter of every commands/gsd/*.md file and
+ * asserts:
+ *   1. No command file has an `agent:` frontmatter directive at all.
+ *      (The directive causes OpenCode to auto-dispatch, breaking any command
+ *      that relies on the Agent tool to spawn subagents.)
+ *   2. Any command whose allowed-tools includes `Agent` (an orchestrator) must
+ *      not have `agent:` in its frontmatter.
