Workflow Start

Primary entry point for spec-superflow. Jobs: inspect change context, check for updates, confirm DP-0, determine state, route to correct skill, block invalid transitions.

Use This Skill When

Only invoke when spec-superflow context is present: .spec-superflow.yaml exists, artifacts like proposal.md/specs//design.md/tasks.md/execution-contract.md are present, or user explicitly invokes spec-superflow by name. When in doubt, check for .spec-superflow.yaml first.

Do NOT invoke for: general coding tasks outside spec-superflow changes, casual questions, unrelated work.

States

exploring → specifying → bridging → approved-for-build → executing → closing, with debugging side-path from executing, and abandoned as terminal. Read docs/state-machine.md if transition is ambiguous.

Initialization

1. Update check: Run node "${CLAUDE_PLUGIN_ROOT}/scripts/check-update.mjs". Exit 0 → continue. Exit 1 → non-blocking upgrade reminder. Exit 2 → skip.
2. Inspect change folder: Check for proposal.md, specs/, design.md, tasks.md, execution-contract.md. Answer: Is the change fuzzy? Artifacts missing/unstable? Contract exist? User approved contract? Execution in progress or blocked? In verification/wrap-up?
3. Overlay recovery scan: Run ssf handoff list <change-dir> --json and ssf checkpoint list <change-dir> --json. A result-ready handoff requires explicit review and ssf handoff resolve before resuming the affected work. An active handoff is non-blocking side work. Show a non-stale checkpoint as recovery context; show a stale checkpoint only as historical evidence.
4. Execution-control recovery scan: For approved-for-build, executing, debugging, or closing, run ssf execution show <change-dir> --json. Treat only current: true plus waves[].eligible: true as permission to start a wave; report plan revision, mode, next eligible wave, and every wave's receipt/blockers. A missing, invalid, or stale plan blocks implementation and routes to build-executor; do not infer progress from chat history.

DP-0: User Confirmation Gate

Run DP-0 when: change folder doesn't exist, planning artifacts missing/empty, or dp_0_confirmed ≠ true. Skip if dp_0_confirmed is true.

Ask: change name + one-sentence intent, known constraints, related optimizations (include or stay focused?), communication preference (ask per decision or draft for review).

After confirmation:

node "${CLAUDE_PLUGIN_ROOT}/scripts/spec-superflow.mjs" state set <change-dir> dp_0_decisions "<summary>"
node "${CLAUDE_PLUGIN_ROOT}/scripts/spec-superflow.mjs" state set <change-dir> dp_0_result confirmed
node "${CLAUDE_PLUGIN_ROOT}/scripts/spec-superflow.mjs" state set <change-dir> dp_0_confirmed true
node "${CLAUDE_PLUGIN_ROOT}/scripts/spec-superflow.mjs" state set <change-dir> dp_0_timestamp $(date -u +%Y-%m-%dT%H:%M:%SZ)

Config-aware routing: check artifacts.order and artifacts.skip from project config.

Mode Detection

If workflow is auto/null/unset: run node "${CLAUDE_PLUGIN_ROOT}/scripts/infer-workflow.mjs" <change-dir>. Inference: hotfix (≤2 tasks, ≤2 files, no schema/API/new modules), tweak (≤4 tasks, config/doc only), full (anything larger). Persist with node "${CLAUDE_PLUGIN_ROOT}/scripts/spec-superflow.mjs" state set <dir> workflow <mode>.

Validate mode against artifact content. If hotfix/tweak criteria not met → upgrade to full and output reason. Don't overwrite explicit mode unless user asks.

Routing Rules

Route to need-explorer

Change is fuzzy, scope unclear, comparing options, no stable change name.

Route to spec-writer

Guard: node "${CLAUDE_PLUGIN_ROOT}/scripts/guard/guard.mjs" check <dir> exploring specifying --json → fail = BLOCK. User knows what they want, artifacts missing/incomplete.

Route to contract-builder

Guard: ... check <dir> specifying bridging --json → fail = BLOCK. Artifacts exist, implementation requested, contract missing/stale. Include DP-3: 契约批准.

Route to build-executor

Contract exists and approved, contract matches artifacts. Include DP-4: 执行模式选择. Before the first implementation edit, build-executor must run ssf execution plan <change-dir> ..., then ssf execution show <change-dir> --json; report the saved revision, selected mode, ordered waves, and actual concurrent-dispatch capability. Do not transition to executing until show reports current: true; then run ... check <dir> approved-for-build executing --json → fail = BLOCK.

Route to bug-investigator

Execution hit blockage: test failure, unexpected behavior, build error, task cannot proceed. After debugging, route back to build-executor.

Route to code-reviewer

The current planned wave is implemented and ready for spec-compliance + code-quality verification. A reviewer must write an ssf execution review <change-dir> --wave <id> --base <sha> --head <sha> --report <path> --verdict <pass|fail> receipt before any dependent wave or closing transition.

Route to release-archivist

Guard: ... check <dir> executing closing --json → fail = BLOCK. Implementation complete, verification complete/nearly complete. Include DP-7: 归档确认.

Route to spec-merger

Delta specs exist that need merging, change closing with ADDED/MODIFIED/REMOVED/RENAMED specs.

Route to abandoned

User explicitly requests, bug-investigator escalates after 3+ failures AND user chooses, scope change makes change no longer worthwhile AND user confirms. Block from closing or abandoned.

Optional Prototype Handoff

When the user's brief explicitly contains UI, screen, interaction, layout, UX, or product-experience uncertainty, ask once whether a prototype would reduce uncertainty. Do not create a prototype handoff or enter a prototype worktree until the user confirms. After confirmation:

node "${CLAUDE_PLUGIN_ROOT}/scripts/spec-superflow.mjs" handoff create <change-dir> \
  --type prototype --objective "<confirmed objective>" \
  --expected-output "<expected evidence>" --acceptance "<completion criterion>"
node "${CLAUDE_PLUGIN_ROOT}/scripts/spec-superflow.mjs" isolate <change-dir> prototype-<handoff-id>

Never suggest or enter this route automatically for backend, CLI, configuration, or internal-refactor work. Never pass --force to ssf isolate for prototype work.

Fast-Path Routing

• Hotfix: Route to contract-builder (minimal), skip need-explorer + spec-writer, guard check exploring bridging --workflow hotfix, then bridging -> approved-for-build, after DP-3 → build-executor (default SDD plan), after → release-archivist (lightweight). Hotfix may skip proposal.md, design.md, tasks.md, and specs/, but it still requires a fresh minimal execution-contract.md, DP-3 approval, and a current execution plan before build
• Tweak: Route to build-executor (direct edit), skip need-explorer + spec-writer + contract-builder, guard check exploring approved-for-build --workflow tweak, after → release-archivist (lightweight)

Post-transition: 💡 node "${CLAUDE_PLUGIN_ROOT}/scripts/spec-superflow.mjs" inject <change-dir> to update phase-guard artifacts.

Staleness Detection

Use content inspection, not timestamps.

Stale contract: proposal scope expanded beyond contract scope fence, or contract references capabilities no longer in proposal → route back to contract-builder.

Stale planning artifacts: capability in proposal has no spec file, or spec exists for capability not in proposal → drift detected.

Stale tasks: requirement in specs has no corresponding task → stale tasks.

Guardrails

• No implementation before planning artifacts or contract exist
• No implementation for full/hotfix without a current ssf execution plan; no state transition based on an unverified DP-4 string
• No "continue" without state inspection
• No implementation past stale contract
• No implementation past bug without investigation
• No closure without all planned wave review receipts recorded as pass
• No closure with unsynced delta specs
• No transitions from abandoned (terminal)
• No transition to abandoned from closing or abandoned
• No auto-abandon without user confirmation
• No merging delta specs from abandoned change

Output Standard

Always state: (1) current detected state, (2) why (cite file/content/condition), (3) which skill should run next. If blocking, explain missing artifact/approval.

Decision point references when routing:

• contract-builder → DP-3, build-executor → DP-4, bug-investigator (escalation) → DP-5, release-archivist (verification failure) → DP-6, release-archivist → DP-7

Exception Handling

• Parse failures: Fall back to content-level detection if .spec-superflow.yaml is malformed
• Missing files: Route to the skill that generates the missing files
• User interruption: Re-inspect change directory content (not cached state) on resume
