Coordinator

Orchestrate skills through a phased workflow: brainstorm, challenge, design/plan, challenge, implement, finish.

Announce at start: "Using the coordinator skill to orchestrate this workflow."

Determine Scope

Classify the request before starting:

Ask if unclear: "Is this an idea exploration, a plan, or a full build?"

Phases

Phase 1: Brainstorm

1. Load and apply the brainstormer skill
   • Generate diverse ideas across multiple thinking frameworks
   • Produce 2-4 ideas per framework, covering 3-5 frameworks
2. Load and apply the brainstorming skill
   • Refine the best ideas through collaborative dialogue
   • Present design in sections, validate incrementally

Output: Refined ideas with rationale and top picks.

Checkpoint: Present top ideas. Continue unless redirected.

Phase 2: Challenge Ideas

1. Load and apply the challenger skill
   • Attack ideas across all dimensions (security, correctness, performance, scalability, UX, maintainability, edge cases)

Gate:

• Critical issues found → STOP. Present issues, ask how to proceed.
• Medium/low only → Summarize findings, continue automatically.

Output: Challenge report with severity ratings.

For Idea scope: Stop here. Present final deliverable.

Phase 3: Design & Plan

Run applicable sub-phases:

3a. Design (if UI/UX involved):

• Load and apply the designer skill
• Review and improve UX, produce design recommendations

3b. Plan:

• Load and apply the planner skill
• Create structured plan with approaches, trade-offs, risks

3c. Implementation Plan (Build scope only):

• Load and apply the writing-plans skill
• Create detailed task-level implementation plan with file paths and code examples

Checkpoint: Present the plan. Continue unless redirected.

For Plan scope: Stop here. Present final deliverable.

Phase 4: Challenge Plan

1. Load and apply the challenger skill again
   • Evaluate the plan for risks, missing steps, wrong ordering, feasibility

Gate:

• Critical issues found → Revise plan based on findings, re-challenge. Max 2 revision cycles.
• Medium/low only → Summarize, continue automatically.

Output: Validated, battle-tested plan.

Phase 5: Implement

1. Load and apply the test-driven-development skill
   • TDD is mandatory: no production code without a failing test first
2. Load and apply the executing-plans skill
   • Execute plan in controlled batches with review checkpoints

Within each batch:

• RED: Write failing test
• GREEN: Minimal code to pass
• REFACTOR: Clean up, stay green
• Review between batches

Gate:

• Tests failing after 2 fix attempts → STOP. Report issue, ask for direction.
• Batch complete → Brief summary, continue to next batch.

Phase 6: Finish

1. Load and apply the finishing-a-development-branch skill
   • Verify all tests pass
   • Present completion options (merge, PR, keep, discard)
   • Clean up worktree if applicable

Key Principles

• One skill at a time — Load and complete each skill before moving to the next.
• Challenge gates — Critical issues block progress; medium/low don't.
• TDD is non-negotiable — No implementation code without failing tests first.
• Incremental validation — Check with human at phase boundaries.
• Skip what doesn't apply — Not every request needs all phases.
• Autonomy with guardrails — Run freely, stop when uncertain or blocked.
