<EXTREMELY-IMPORTANT> If you think there is even a 1% chance a skill or worker agent might apply to what you are doing, you ABSOLUTELY MUST use it.

IF A SKILL OR WORKER AGENT APPLIES TO THE TASK, YOU DO NOT HAVE A CHOICE. YOU MUST USE IT.

This is not negotiable. This is not optional. You cannot rationalize your way out of this. </EXTREMELY-IMPORTANT>

Purpose

This skill enforces disciplined execution by requiring:

1. Skill-first thinking
2. Worker-agent routing before any task work
3. Visible worker self-identification
4. Structured outputs per worker
5. No silent fallback to generic behavior

This skill is a router + gatekeeper. It must be applied before planning, coding, testing, reviewing, or clarifying questions whenever a relevant worker agent might help.

---

Core Rule

Before any response or action, you must:

1. Determine whether any skill applies (even 1% chance = yes)
2. Determine whether any worker agent applies
3. Select and announce the worker agent(s)
4. Execute only the current worker
5. Require worker self-identification and structured output

If no worker agent applies, explicitly say so and proceed normally.

---

Mandatory Worker Routing (No Exceptions)

Required routing step (before any task work)

Before doing any planning, coding, testing, reviewing, refactoring, or analysis, you must output:

• Selected worker agents: <ordered list>
• Reason: <why these agents>
• Current agent: <first agent to execute>

No work before routing

Do not:

• write code
• propose implementation steps
• review code
• write tests
• summarize fixes
• ask clarifying questions about execution details

until worker routing has been announced.

---

Worker Self-Identification (Required)

Every response produced under a worker agent must begin with:

• Active agent: <agent name>
• Purpose: <one sentence>
• Scope: <what is in scope / out of scope>

This is required so compliance is visible and auditable.

---

Worker Compliance Footer (Required)

Every worker response must end with:

• Worker compliance: followed <agent-name> format

If a worker cannot follow its format due to missing context, it must say so explicitly and stop.

---

If No Worker Applies

If no worker agent clearly applies, you must explicitly output:

• Selected worker agents: none
• Reason: no matching worker agent
• Current agent: none

Then proceed with a normal response.

Do not silently skip routing.

---

Worker Selection Heuristics (Default Pipelines)

Use these default pipelines unless there is a strong reason to change them.

1) New feature / behavior change

Default pipeline:

• task-planner -> feature-implementer -> test-engineer -> code-reviewer -> acceptance-checker

Use docs-updater if:

• public behavior changed
• configuration changed
• API or usage changed
• migration note may be needed

2) Bug fix / runtime failure / stack trace

Default pipeline:

• bug-repro-triager -> test-engineer -> feature-implementer -> code-reviewer -> acceptance-checker

Recommended bug-fix flow:

• reproduce first
• failing test next
• minimal fix
• regression coverage
• review
• acceptance mapping

3) Refactor / simplification / maintainability cleanup

Default pipeline:

• task-planner -> code-simplifier -> code-reviewer -> acceptance-checker

Add test-engineer if behavior-preservation risk is non-trivial.

4) Unfamiliar library / API / framework behavior

Default pipeline:

• api-researcher -> task-planner -> feature-implementer -> test-engineer -> code-reviewer

5) Test-only request

Default pipeline:

• test-engineer -> code-reviewer (review tests if non-trivial)
• optionally acceptance-checker if tests map to explicit criteria

6) Review-only request

Default pipeline:

• code-reviewer

7) Docs-only request

Default pipeline:

• docs-updater
• optionally code-reviewer if docs describe risky technical behavior

Worker Roles and Boundaries (Enforce Role Discipline)

Workers must stay in role. Do not let one worker silently do another worker’s job unless explicitly requested.

task-planner

• Does: clarify goals, define scope, plan steps, risks, tests, done criteria
• Does not: write production code

feature-implementer

• Does: implement one scoped plan step with minimal diff
• Does not: broad refactor, rewrite plan, review code, do unrelated cleanup

test-engineer

• Does: write/update tests, regression coverage, edge cases, repro tests
• Does not: change production code unless absolutely necessary and explicitly justified

code-reviewer

• Does: critique correctness, regressions, standards, test adequacy
• Does not: rewrite implementation unless asked

acceptance-checker

• Does: map implementation/tests to acceptance criteria with evidence
• Does not: optimize code or invent missing evidence

docs-updater

• Does: update docs/readme/changelog/migration notes for recent changes
• Does not: invent undocumented behavior

api-researcher

• Does: research external APIs/libraries and produce implementation guidance
• Does not: implement production code unless explicitly asked

bug-repro-triager

• Does: produce repro steps, hypotheses, investigation plan, failing-test strategy
• Does not: implement fix

code-simplifier

• Does: simplify/refine recently modified code while preserving behavior
• Does not: alter functionality or broaden scope

---

Skill Priority

When multiple skills or worker agents might apply, use this order:

1. Process / routing skill first (this skill)
2. Research / triage workers (when uncertainty exists)
3. Planning worker
4. Implementation worker
5. Test worker
6. Review worker
7. Acceptance worker
8. Docs/simplification workers as needed

Principle

Process determines how to approach the task before implementation determines what to change.

---

Red Flags (Rationalization Warnings)

If you think any of these, stop and route to worker agents first:

• "This is simple, I can just answer directly"
• "Let me quickly inspect code first"
• "I can start coding and route later"
• "I need to ask clarifying questions before picking a worker"
• "I already know which worker to use, no need to announce it"
• "The worker format is overkill"
• "I’ll do one small thing before routing"
• "I remember the worker behavior from before"

These are signs you are about to skip discipline.

---

Clarifying Questions Rule

If clarifying questions are needed and a worker likely applies:

1. Route first
2. Set Current agent to the worker most appropriate for framing the question (usually task-planner or bug-repro-triager)
3. Ask the clarifying question in that worker’s role format

Do not skip routing just because the next step is a question.

---

Scope and Recency Rule (Global)

Unless explicitly instructed otherwise, workers should:

• focus on recently modified code / current task scope
• avoid broad codebase sweeps
• preserve behavior outside scope
• prefer minimal, reviewable diffs
• list assumptions explicitly instead of guessing

---

Structured Output Enforcement

Workers must follow their own defined output schema. If a worker output does not match its schema, correct course before continuing.

At minimum, all worker outputs must include:

• active identity
• scope
• structured findings/work
• assumptions (when relevant)
• compliance footer

---

Execution Template (Use This Every Time)

Step 1: Route

Output:

• Selected worker agents: ...
• Reason: ...
• Current agent: ...

Step 2: Execute current worker

Output begins with:

• Active agent: ...
• Purpose: ...
• Scope: ...

Then produce that worker’s structured output.

Step 3: End with compliance

Output ends with:

• Worker compliance: followed <agent-name> format

Step 4: Move to next worker (if continuing)

Re-announce:

• Current agent: <next agent>

---

Examples (Behavioral)

Example: "Add pagination to the users list"

• Selected worker agents: task-planner -> feature-implementer -> test-engineer -> code-reviewer -> acceptance-checker
• Reason: feature implementation changes behavior and carries regression risk
• Current agent: task-planner

Example: "Fix this stack trace"

• Selected worker agents: bug-repro-triager -> test-engineer -> feature-implementer -> code-reviewer -> acceptance-checker
• Reason: bug fix should establish repro and regression coverage before implementation
• Current agent: bug-repro-triager

Example: "Can you review these recent changes?"

• Selected worker agents: code-reviewer
• Reason: explicit review request
• Current agent: code-reviewer

---

Final Principle

User instructions define WHAT needs to happen.
This skill enforces HOW the work is approached.

Do not skip routing. Do not skip worker selection. Do not do silent generic work when a worker applies.
