Quick Summary

Goal: [Workflow] Trigger Feature Implementation workflow — implement a well-defined feature with investigation, planning, implementation, and review.

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.
• 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 3)	PLAN₁: Investigation-based implementation plan
/plan	2nd (pos 9)	PLAN₂: Sprint-ready plan incorporating TDD specs
/plan-review	1st (pos 4)	Review PLAN₁
/plan-review	2nd (pos 10)	Review PLAN₂
/tdd-spec	1st (pos 7)	TDD-SPEC₁: Pre-implementation test specs
/tdd-spec	2nd (pos 11)	TDD-SPEC₂: Post-implementation test spec update
/tdd-spec-review	1st (pos 8)	Review TDD-SPEC₁
/tdd-spec-review	2nd (pos 12)	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 /feature-investigation):

• If image/wireframe/Figma URL is provided → route to /wireframe-to-spec 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 step = TaskUpdate in_progress → Skill tool → complete skill → TaskUpdate completed. No shortcuts.

[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.

IMPORTANT MANDATORY Steps: /scout -> /investigate -> /domain-analysis -> /why-review -> /plan -> /why-review -> /plan-review -> /why-review -> /plan-validate -> /why-review -> /tdd-spec -> /why-review -> /tdd-spec-review -> /plan -> /why-review -> /plan-review -> /why-review -> /cook -> /review-domain-entities -> /tdd-spec -> /why-review -> /tdd-spec-review -> /tdd-spec [direction=sync] -> /integration-test -> /integration-test-review -> /integration-test-verify -> /workflow-review-changes -> /sre-review -> /security -> /changelog -> /test -> /docs-update -> /watzup -> /workflow-end

[BLOCKING] Each step MUST ATTENTION invoke its Skill tool — marking a task completed without skill invocation is a workflow violation. NEVER batch-complete validation gates.

Activate the feature workflow. Run /workflow-start 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 → /domain-analysis → /why-review → /plan → /why-review → /plan-review → /why-review → /plan-validate → /why-review → /tdd-spec → /why-review → /tdd-spec-review → /plan → /why-review → /plan-review → /why-review → /cook → /review-domain-entities → /tdd-spec → /why-review → /tdd-spec-review → /tdd-spec [direction=sync] → /integration-test → /integration-test-review → /integration-test-verify → /workflow-review-changes → /sre-review → /security → /changelog → /test → /docs-update → /watzup → /workflow-end

[PERFORMANCE EXCEPTION] If this feature is a performance enhancement (query optimization, caching, throughput improvement, latency reduction), skip /tdd-spec (both occurrences), /tdd-spec-review (both occurrences), PLAN₂ + its /plan-review, /tdd-spec [direction=sync], /integration-test, /integration-test-review, and /integration-test-verify. Do NOT skip /cook — implementation still runs. Integration tests verify functional correctness — they cannot measure performance. Use /test only to confirm no functional regressions. Activate /workflow-performance instead.

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.

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.

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

Check downstream references before deleting. Deleting components causes documentation and code staleness cascades. Map all referencing files before removal. Verify AI-generated content against actual code. AI hallucinates APIs, class names, and method signatures. Always grep to confirm existence before documenting or referencing. Trace full dependency chain after edits. Changing a definition misses downstream variables and consumers derived from it. Always trace the full chain. Trace ALL code paths when verifying correctness. Confirming code exists is not confirming it executes. Always trace early exits, error branches, and conditional skips — not just happy path. When debugging, ask "whose responsibility?" before fixing. Trace whether bug is in caller (wrong data) or callee (wrong handling). Fix at responsible layer — never patch symptom site. Assume existing values are intentional — ask WHY before changing. Before changing any constant, limit, flag, or pattern: read comments, check git blame, examine surrounding code. Verify ALL affected outputs, not just the first. Changes touching multiple stacks require verifying EVERY output. One green check is not all green checks. Holistic-first debugging — resist nearest-attention trap. When investigating any failure, list EVERY precondition first (config, env vars, DB names, endpoints, DI registrations, data preconditions), then verify each against evidence before forming any code-layer hypothesis. Surgical changes — apply the diff test. Bug fix: every changed line must trace directly to the bug. Don't restyle or improve adjacent code. Enhancement task: implement improvements AND announce them explicitly. Surface ambiguity before coding — don't pick silently. If request has multiple interpretations, present each with effort estimate and ask. Never assume all-records, file-based, or more complex path.

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

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.

• 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.

Closing Reminders

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.
