workflow-feature

Quick Summary

Goal: [Workflow] Trigger Feature Implementation workflow — implement a well-defined feature with investigation, planning, implementation, and review. This workflow is spec-driven with tests by default: test specs (/spec [mode=tests]) are written and reviewed BEFORE implementation (/plan-execute), covering former TDD/test-first use cases.

Workflow:

1. Detect — classify request scope and target artifacts.
2. Execute — apply required steps with evidence-backed actions.
3. Verify — confirm constraints, output quality, and completion evidence.

Key Rules:

• MUST ATTENTION keep claims evidence-based (file:line) with confidence >80% to act.
• MUST ATTENTION keep task tracking updated as each step starts/completes.
• MUST ATTENTION when creating/reviewing specs or tests, name Business Intent / Invariant Guarded or the protected business intent/invariant and ensure the test would fail if that intent breaks.
• MUST ATTENTION define success criteria before execution and loop until observable verification passes.
• MUST ATTENTION require test specs/tests to name Business Intent / Invariant Guarded and fail if that intent breaks.
• MUST ATTENTION apply the shared SDD Artifact Contract from shared/sdd-artifact-contract.md in the active skills root; use docs/project-config.json and docs/project-reference/docs-index-reference.md for project-specific conventions.
• MUST ATTENTION preserve expected, unchanged, and no-regression behavior in the plan and review evidence when behavior can change.
• MUST ATTENTION treat code-extracted specs and TCs as reference-only until canonical review accepts them.
• MUST ATTENTION allow any supported AI tool to implement or review when the shared contract, synced context, and local docs are available.
• NEVER skip mandatory workflow or skill gates.

Repeated Steps Disambiguation (CRITICAL for task creation)

This workflow has steps that appear multiple times. When creating tasks, use these descriptions to distinguish them:

Step	Occurrence	Task Description
/plan	1st (pos 8)	PLAN₁: Feature Spec-backed implementation plan
/plan	2nd (pos 15)	PLAN₂: Sprint-ready plan incorporating TDD specs
/plan-review	1st (pos 9)	Review PLAN₁
/plan-review	2nd (pos 16)	Review PLAN₂
/spec [mode=tests]	1st (pos 12)	TDD-SPEC₁: Pre-implementation test specs
/spec [mode=tests]	2nd (pos 20)	TDD-SPEC₂: Post-implementation test spec update
/artifact-review --type=spec-tests	1st (pos 14)	Review TDD-SPEC₁
/artifact-review --type=spec-tests	2nd (pos 22)	Review TDD-SPEC₂

NEVER deduplicate — each occurrence is a distinct task with a different purpose.

Conditional UI Planning

When a feature involves UI changes (detected during /scout or /investigate):

• If image/wireframe/Figma URL is provided → route to /design-spec --mode=wireframe or /figma-design before /plan
• If /plan detects frontend phases → ensure ui-wireframe-protocol.md sections are included in plan phases
• This is advisory — NOT a mandatory workflow step change. The existing workflow sequence remains unchanged.

Closing Rule

Every non-skipped step = TaskUpdate in_progress → Skill tool → complete skill → TaskUpdate completed. A cited conditional skip explicitly authorized by canonical preActions.injectContext may complete without a skill call.

[TASK-PLANNING] Before acting, analyze task scope and systematically break it into small todo tasks and sub-tasks using TaskCreate.

[IMPORTANT] Analyze how big the task is and break it into many small todo tasks systematically before starting — this is very important.

Existing-behavior trace gate: If the feature modifies an existing final output, persisted state, API response, projection, or user-visible workflow, include an end-to-start trace of the existing path (final reader -> storage/projection -> writer -> producer/origin), feeder paths, invariants to preserve, and forward proof for the intended new behavior before implementation.

Goal Contract propagation (workflow-owned): At workflow start, resolve the active Goal Contract per SYNC:goal-contract-satisfaction-loop (active plan goal.md → plans/goals/{YYMMDD-HHmm}-{slug}/goal.md → create from the feature request). Before /plan-execute, verify the plan's feature success criteria map to the saved criteria. Pass the same goal file reference to every child step — child skills read the SAME saved goal, never a re-derived one from chat memory. Before /workflow-end, emit the final Goal Satisfaction matrix (PASS/FAIL/BLOCKED); workflow completion requires every required criterion PASS or BLOCKED with a user-facing escalation.

IMPORTANT MANDATORY Steps: /scout -> /investigate -> /spec-discovery -> /domain-analysis -> /why-review -> /spec -> /spec-clarify -> /plan -> /plan-review -> /plan-validate -> /why-review -> /spec [mode=tests] -> /why-review -> /artifact-review --type=spec-tests -> /plan -> /plan-review -> /plan-execute -> /seed-test-data -> /domain-entities-review -> /spec [mode=tests] -> /why-review -> /artifact-review --type=spec-tests -> /spec [mode=sync] -> /integration-test -> /integration-test-review -> /integration-test-verify -> /workflow-review-changes -> /security-review -> /changelog -> /test -> /scan --target=domain-entities -> /docs-update -> /demo-guide -> /workflow-end -> /watzup

IMPORTANT MANDATORY Steps: /scout -> /investigate -> /spec-discovery -> /domain-analysis -> /why-review -> /spec -> /spec-clarify -> /plan -> /plan-review -> /plan-validate -> /why-review -> /spec [mode=tests] -> /why-review -> /artifact-review --type=spec-tests -> /plan -> /plan-review -> /plan-execute -> /seed-test-data -> /domain-entities-review -> /spec [mode=tests] -> /why-review -> /artifact-review --type=spec-tests -> /spec [mode=sync] -> /integration-test -> /integration-test-review -> /integration-test-verify -> /workflow-review-changes -> /security-review -> /changelog -> /test -> /scan --target=domain-entities -> /docs-update -> /demo-guide -> /workflow-end -> /watzup

Single-pass steps are self-loop-backed (convergence lives in the skill, not the sequence): /domain-entities-review and both /artifact-review --type=spec-tests occurrences appear once each in the flat sequence with no repeat wired — intentionally. Each carries the full SYNC:double-round-trip-review self-loop (review → validate findings → fix validated findings → full re-review until a clean pass), so a single sequence occurrence still converges to zero findings on its own. The workflow relies on that per-skill loop; it does NOT re-list the step to force convergence. (Contrast the six specialists in /workflow-review-changes steps 3–8, whose scoped-re-run note lives in that skill.)

[BLOCKING] Each non-skipped step MUST ATTENTION invoke its Skill tool — marking a task completed without skill invocation is a workflow violation, except a cited conditional skip explicitly authorized by canonical preActions.injectContext. NEVER batch-complete validation gates.

Activate the workflow-feature workflow. Run /start-workflow workflow-feature with the user's prompt as context.

Spec check (before investigation): If docs/specs/ has a spec for the affected service/module, read the relevant ERD + business-rules + API-contracts files FIRST. Engineering specs provide domain context that reduces investigation time significantly. Command: ls docs/specs/ to discover available app buckets or flat system folders; then probe ls docs/specs/{app-bucket}/ or ls docs/specs/{system-name}/ to find the specific service spec.

Steps: /scout → /investigate → /spec-discovery → /domain-analysis → /why-review → /spec → /spec-clarify → /plan → /plan-review → /plan-validate → /why-review → /spec [mode=tests] → /why-review → /artifact-review --type=spec-tests → /plan → /plan-review → /plan-execute → /seed-test-data → /domain-entities-review → /spec [mode=tests] → /why-review → /artifact-review --type=spec-tests → /spec [mode=sync] → /integration-test → /integration-test-review → /integration-test-verify → /workflow-review-changes → /security-review → /changelog → /test → /scan --target=domain-entities → /docs-update → /demo-guide → /workflow-end → /watzup

[CONDITIONAL TERMINAL DOMAIN-ENTITY REFERENCE REFRESH] After /test and before /docs-update, run /scan --target=domain-entities to refresh the project-reference entity catalog only when the final diff changes an entity/model, DTO/data contract, persistence schema/migration, or entity-sync evidence represented in docs/project-reference/domain-entities-reference.md. Otherwise mark the scan step completed with a cited skip reason naming the changed files and why they are outside this scope; this is the explicitly authorized exception to the per-step skill-invocation rule.

[PERFORMANCE-SDD ROUTE] If this feature is a performance enhancement (latency, throughput, memory, query speed, load behavior), run /performance-review and require SLA/benchmark evidence: target metric, baseline, measurement command, and acceptable regression budget. Run /plan-execute even on the performance route — never skip it. If behavior can change, run /test and any relevant functional no-regression checks. Update docs/specs for changed SLA, performance constraints, or behavior boundaries. Use project-specific performance docs from docs/project-config.json / docs/project-reference/ when available.

[AI-SDD CLOSURE] Before /workflow-end, confirm changed behavior, unchanged behavior, TCs/tests, docs/specs, and generated mirror sync are either completed or explicitly skipped with evidence.

[AI-SDD CLOSURE — POST-IMPLEMENTATION SPEC RE-VERIFY (MANDATORY)] The /spec authored at step 6 (before /plan) captured intended behavior. After /plan-execute, re-verify Feature Spec §1-7 (not only §8 TCs) against what was actually built and adjudicate every divergence per shared/sdd-artifact-contract.md → Drift Gates (SYNC:spec-drift-adjudication): CODE-WRONG → fix code/test against the spec; SPEC-STALE → run /spec [update] to record the new intended behavior, then /spec [mode=tests] [update] + /spec [mode=sync]; AMBIGUOUS → escalate to the spec owner. A feature that shipped behavior the spec does not describe leaves the spec stale and is NOT closure-ready. This re-verify is not optional cleanup — it is the "after implement, verify and create/update specs again" half of the SDD cycle.

UI-intent maintenance (conditional) — runs alongside the /spec [mode=sync] step, only when the change carries user-facing behavior (else state the skip reason — backend-only change, no §6 change). When user-facing behavior is present, run /spec (ui-intent intent) to refresh the affected Feature Spec §6 interaction surface — View Inventory, Key UI States, and the per-story (US-/OP-/BR-) click-path the feature touched — and link the governing /design-spec/mockup in the spec frontmatter so §6 and the design artifact stay coupled to what was actually built. The rules live in the shared block below (SYNC:ui-intent-layer) — follow it; do not restate it here.

<!-- SYNC:end-to-start-debugger-trace -->

End-to-Start Debugger Trace — For non-trivial bugs, failed verification, regression fixes, behavior-changing code, or unclear code flow, start from the observed final state and walk backward before proposing a fix.

1. Frame 0: observed end state — Name the exact user-visible output, failing assertion, log line, persisted value, API response, rendered UI, or aggregate bucket. Record the reader/query/renderer that produced it with file:line evidence.
2. Walk backward one hop at a time — Trace final reader -> projection/cache/storage -> writer -> consumer/handler/job -> producer/caller -> original trigger. At every hop record: input, transformation, output, owner, and evidence.
3. Enumerate all feeder paths — Find every upstream producer/caller/event/job that can write into the final path, including retry, async, cache, background, and alternate UI/API paths. Mark each path verified, ruled out, or still unknown.
4. Build the hypothesis matrix — For each plausible cause, list evidence for, evidence against, how to reproduce/verify, blast radius, and status (primary, contributing, ruled out, latent). Do not fix until competing causes are explicitly resolved or bounded.
5. Choose the owning fix layer — Identify the invariant owner and the lowest shared point that protects all downstream consumers. A fix at the symptom site is rejected unless the symptom site owns the invariant.
6. Prove convergence forward — After choosing the fix, walk start -> end again and show how the corrected state reaches the observed final output. Map each root cause to a fix part and each fix part to a test/proof.

BLOCKED until: final state named · backward trace written · all feeder paths enumerated · hypothesis matrix completed · owning fix layer justified · forward convergence proof mapped to tests.

NEVER: Start at the first suspicious code path. Collapse multiple producers into one "flow". Treat duplicate symptoms as duplicate records without proving the read model. Skip ruled-out hypotheses.

<!-- /SYNC:end-to-start-debugger-trace --> <!-- SYNC:nested-task-creation -->

Nested Task Expansion Contract — For workflow-step invocation, the [Workflow] ... row is only a parent container; the child skill still creates visible phase tasks.

1. Call TaskList first. If a matching active parent workflow row exists, set nested=true and record parentTaskId; otherwise run standalone.
2. Create one task per declared phase before phase work. When nested, prefix subjects [N.M] $skill-name — phase.
3. When nested, link the parent with TaskUpdate(parentTaskId, addBlockedBy: [childIds]).
4. Orchestrators must pre-expand a child skill's phase list and link the workflow row before invoking that child skill or sub-agent.
5. Mark exactly one child in_progress before work and completed immediately after evidence is written.
6. Complete the parent only after all child tasks are completed or explicitly cancelled with reason.

Blocked until: TaskList done, child phases created, parent linked when nested, first child marked in_progress.

<!-- /SYNC:nested-task-creation --> <!-- SYNC:critical-thinking-mindset -->

Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.

<!-- /SYNC:critical-thinking-mindset --> <!-- SYNC:ai-mistake-prevention -->

AI Mistake Prevention — Failure modes to avoid on every task:

Re-read files after context changes. Context compaction, resume, or long-running work can make memory stale; verify current files before acting. Verify generated content against source evidence. AI hallucinates APIs, names, claims, and document facts. Check the relevant source before documenting or referencing. Check downstream references before deleting or renaming. Removing an artifact can stale docs, generated mirrors, configs, and callers; map references first. Trace the full impact chain after edits. Changing a definition can miss derived outputs and consumers. Follow the affected chain before declaring done. Verify ALL affected outputs, not just the first. One green check is not all green checks; validate every output surface the change can affect. Assume existing values are intentional — ask WHY before changing OR flagging one as a defect. Before changing or reporting a constant, limit, flag, cutoff, wording, or pattern, read nearby context and history, the CALLER's ordering, and 2+ sibling call sites of the same convention. A doc stating WHAT without WHY is missing rationale, not proof of a missing guard. Surface ambiguity before acting — don't pick silently. Multiple valid interpretations require an explicit question or stated assumption with risk. Assert the outcome your system owns, not the intermediate state your infrastructure owns. When verifying async work, assert the final business state — never the delivery/retry bookkeeping held in shared infrastructure that any co-running process can write. Such a check passes when run alone and flakes the moment anything else shares that infrastructure. Keep shared guidance role-relevant. Universal guidance must help every receiving skill or agent; code-specific obligations belong only in code-specific protocols.

<!-- /SYNC:ai-mistake-prevention --> <!-- SYNC:incremental-persistence -->

Incremental Result Persistence — MANDATORY for all sub-agents or heavy inline steps processing >3 files.

1. Before starting: Create report file plans/reports/{skill}-{date}-{slug}.md
2. After each file/section reviewed: Append findings to report immediately — never hold in memory
3. Return to main agent: Summary only (per SYNC:subagent-return-contract) with Full report: path
4. Main agent: Reads report file only when resolving specific blockers

Why: Context cutoff mid-execution loses ALL in-memory findings. Each disk write survives compaction. Partial results are better than no results.

Report naming: plans/reports/{skill-name}-{YYMMDD}-{HHmm}-{slug}.md

<!-- /SYNC:incremental-persistence --> <!-- SYNC:subagent-return-contract -->

Sub-Agent Return Contract — When this skill spawns a sub-agent, the sub-agent MUST return ONLY this structure. Main agent reads only this summary — NEVER requests full sub-agent output inline.

## Sub-Agent Result: [skill-name]

Status: ✅ PASS | ⚠️ PARTIAL | ❌ FAIL
Confidence: [0-100]%

### Findings (Critical/High only — max 10 bullets)

- [severity] [file:line] [finding]

### Actions Taken

- [file changed] [what changed]

### Blockers (if any)

- [blocker description]

Full report: plans/reports/[skill-name]-[date]-[slug].md

Main agent reads Full report file ONLY when: (a) resolving a specific blocker, or (b) building a fix plan. Sub-agent writes full report incrementally (per SYNC:incremental-persistence) — not held in memory.

Context budget — the return payload is a SUMMARY, not a transcript: ≤10 finding bullets, no raw file contents / full diffs / verbatim logs inline, no re-pasted source. Everything beyond the summary lives in the Full report on disk. A sub-agent that would exceed the summary shape MUST write the detail to its report and return only the pointer — the orchestrator's context is the scarce resource the whole map-reduce protects.

<!-- /SYNC:subagent-return-contract --> <!-- SYNC:ui-intent-layer -->

[BLOCKING] Capture a tech-agnostic UI/UX intent layer in every UI-bearing spec — a reader must be able to visualize how the feature works without naming any technology. When the feature has a user interface, the spec MUST ATTENTION carry an interaction-surface section so the application — not just its API — can be rebuilt on any stack:

1. View Inventory — list each view/screen by its UX ROLE and purpose (e.g. "list of items", "item editor", "confirmation step") and what information it presents. Describe by role, never by an implementation name.
2. Navigation Map — how a user moves between views: entry points, transitions, and exits. Trace how this surface connects to neighboring features already in the system.
3. Key observable UI States — the distinct states a user can observe per view (empty, loading, populated, error, success, permission-denied, etc.) — described as what the user perceives, not how it is rendered.
4. Per-story interaction flow — for each user story, the step-by-step click/action path from intent to outcome, cross-referenced to the logical IDs the spec already owns (US-/OP-/BR-).
5. Couple to the companion design artifact — keep deep visual fidelity (layout, tokens, pixel detail) OUT of the spec; it lives in the linked design-spec/mockup. Record that companion's path in the spec frontmatter so the spec stays the navigable hub.

M1-clean (NON-NEGOTIABLE): the prose names ZERO frameworks, routes/URLs, CSS, or component-class names — only roles, information, states, and flows. Technology detail belongs in the companion design artifact, never here.

Skip ONLY when the feature is backend-only (no UI) — state that reason explicitly in the section.

<!-- /SYNC:ui-intent-layer --> <!-- SYNC:end-to-start-debugger-trace:reminder -->

IMPORTANT MUST ATTENTION debugger trace gate: for non-trivial bug/fix/investigation/review work, start at the observed final output and trace backward through reader -> storage/projection -> writer -> consumer/job -> producer/trigger. Enumerate all feeder paths and hypotheses before fixing. BLOCKED until trace, hypothesis matrix, owning fix layer, and forward convergence proof exist.

• MANDATORY Parent workflow rows do not replace child phase tracking; expand phases and link the parent when nested.
• MANDATORY Orchestrators pre-expand child skill phases before invocation; use [N.M] $skill-name — phase prefixes and one-in_progress discipline.

<!-- /SYNC:nested-task-creation:reminder --> <!-- SYNC:goal-contract-satisfaction-loop:reminder -->

• MANDATORY Resolve the active Goal Contract BEFORE work (active plan goal.md → plans/goals/{YYMMDD-HHmm}-{slug}/goal.md → create from current request) and read saved success criteria before editing.
• MANDATORY Append iteration evidence after execution; emit a Goal Satisfaction matrix (PASS/FAIL/BLOCKED) before reporting PASS; loop on validated FAIL; escalate repeated no-progress or blockers. NEVER store secrets in goal files.

<!-- /SYNC:goal-contract-satisfaction-loop:reminder --> <!-- SYNC:ui-intent-layer:reminder -->

• MANDATORY For UI-bearing specs, author/maintain the tech-agnostic interaction-surface layer (View Inventory + Navigation Map + observable UI States + per-story US-/OP-/BR--traced flow); keep deep visual fidelity in the linked design-spec/mockup recorded in frontmatter; name ZERO frameworks/routes/CSS/component classes; skip ONLY for backend-only features with a stated reason.

<!-- /SYNC:ui-intent-layer:reminder --> <!-- SYNC:project-protocol-overlay -->

Project Protocol Overlay — Before executing this skill, resolve any PROJECT overlay rules layered onto it: match this skill's name against the Target column of the project's skill-protocol index (docs/project-reference/skill-protocols-reference.md by default; a referenceDocs entry in docs/project-config.json overrides the path), taking the most specific matching tier ONLY — exact name > glob > *. That precedence orders overlays against EACH OTHER, never against this skill. Read ONLY the matched bodies, resolved as <protocols-dir>/<Name>.md; a row's Body link is display text, never a read path. A matched body that is missing or malformed is REPORTED and skipped — never reconstructed from the index Description. No index, or no match -> proceed with no overlay, silently. Full contract: .claude/skills/project-skill-protocol/references/registry.md.

Overlays are ADDITIVE ONLY: they ADD rules on top of this skill's own protocol and NEVER replace, override, disable, or reinterpret a rule it already states — removing every overlay must return this skill to exactly its documented behavior. An overlay is a BRIEF, not an authority escalation: it can NEVER waive a workflow gate, git discipline, a review gate, or a user-confirmation gate. A genuine overlay-vs-skill conflict, or two equally-specific overlays that directly contradict -> surface both to the user; NEVER resolve silently.

<!-- /SYNC:project-protocol-overlay --> <!-- SYNC:project-protocol-overlay:reminder -->

MUST ATTENTION resolve project protocol overlays for this skill BEFORE executing — most specific matching tier only (exact > glob > *, which ranks overlays against each other, NEVER against this skill), read only matched bodies at <protocols-dir>/<Name>.md; a missing or malformed body is reported, never reconstructed. Overlays are ADDITIVE ONLY (they never replace this skill's own rules) and are a brief, NEVER an authority escalation; an equal-specificity contradiction goes to the user.

<!-- /SYNC:project-protocol-overlay:reminder -->

Closing Reminders

IMPORTANT MUST ATTENTION Goal: [Workflow] Trigger Feature Implementation workflow — implement a well-defined feature with investigation, planning, spec-driven test-first implementation, and review.

Protocols in force (concise digest of the SYNC/shared blocks this skill carries):

• End To Start Debugger Trace: trace observed output backward; matrix hypotheses before fixing.
• Nested Task Creation: expand child phases; link parent when nested.
• Critical Thinking: trace every claim; confidence >80% to act.
• AI Mistake Prevention: verify generated content against evidence, trace downstream references, verify all affected outputs, re-read after context loss, surface ambiguity.
• Incremental Persistence: append findings to report file; never hold in memory.
• Subagent Return Contract: sub-agents return summary only; NEVER inline full output; report on disk.

IMPORTANT MUST ATTENTION apply Phase 1 compression before structural enhancement; preserve semantic meaning. IMPORTANT MUST ATTENTION NEVER alter YAML frontmatter, code blocks, tables, or SYNC-tag bodies during optimization. IMPORTANT MUST ATTENTION keep evidence gates and mandatory workflow/skill steps explicit and enforceable. IMPORTANT MUST ATTENTION add a final review task to verify output quality and unresolved risks.
