SKILL.md
plugin-planning Skill
Purpose: Handle Stage 0 (Research & Planning - consolidated) through subagent delegation. This skill creates the foundation contracts (architecture.md, plan.md) that guide implementation in a single consolidated pass.
Invoked by: /plan command or as first step of /implement workflow
Entry Point
Check preconditions first: See [references/preconditions.md](references/preconditions.md) for detailed validation logic.
Quick validation:
- creative-brief.md must exist at
plugins/[Name]/.ideas/
- Parameter specification required (parameter-spec.md OR parameter-spec-draft.md)
- Plugin status must be ≤ Stage 0 (not already in implementation)
- Detect existing contracts (architecture.md, plan.md) for resume logic
If all preconditions pass → proceed to Stage 0
Stage 0: Research & Planning
Goal: Create DSP architecture specification (architecture.md) AND implementation plan (plan.md) Duration: 5-35 minutes (complexity-dependent) Implementation: Delegated to research-planning-agent subagent via Task tool
Dispatch pattern:
- Read contracts in parallel (use parallel Read calls in single tool invocation):
- plugins/[Name]/.ideas/creative-brief.md - plugins/[Name]/.ideas/parameter-spec.md OR parameter-spec-draft.md - plugins/[Name]/.ideas/mockups/*.yaml (if exists)
- Invoke subagent:
`` Task(subagent_type="research-planning-agent", description="[prompt with contracts]", model="sonnet") ``
See [references/subagent-invocation.md](references/subagent-invocation.md) for detailed prompt construction.
- After subagent returns, execute checkpoint protocol:
- Read subagent's return message - Verify architecture.md and plan.md created - Present decision menu (use assets/decision-menu-stage-0.md template) - WAIT for user response
Subagent executes: Full Stage 0 protocol from research-planning-agent.md
Outputs:
plugins/[Name]/.ideas/architecture.md (see assets/architecture-template.md)
plugins/[Name]/.ideas/plan.md (see assets/plan-template.md)
Decision menu: Use assets/decision-menu-stage-0.md template
Menu option routing:
- Option 1 (Start implementation): Invoke plugin-workflow skill
- Option 2 (Review contracts): Read and display architecture.md, plan.md, parameter-spec.md, creative-brief.md
- Option 3 (Improve brief): Invoke plugin-ideation skill
- Option 4 (Deep research): Invoke deep-research skill
- Option 5 (Pause): Verify state saved, exit skill
- Option 6 (Other): Route based on request (plugin-workflow, ui-mockup, deep-research, or handle directly)
Note: research-planning-agent runs in fresh context (5-35 min session doesn't pollute orchestrator)
Validation before proceeding to Stage 1:
- Verify architecture.md exists with all required sections (Core Components, Processing Chain, Parameter Mapping)
- Verify plan.md exists with complexity score and implementation strategy
- If verification fails: Display error and return to Stage 0
- When user chooses option 1: Delegate to plugin-workflow skill (plugin-workflow owns Stages 1-4)
