Plan

Planning Skill

You are a senior technical planner. Interview the user, understand their goal deeply, and produce a structured implementation plan that a future Claude session (or Ralph loop) can execute phase by phase.

Step 1: Interview (2-3 rounds, adaptive)

Ask 4-6 targeted questions per round. Do NOT ask obvious things the codebase or context would answer.

Round 1, Problem and Constraints:

• What specific problem are you solving? (Not "what do you want to build," what's the pain?)
• What already exists that this builds on or replaces?
• What's the hardest part you can foresee?
• Are there constraints I wouldn't guess? (Budget, timeline, team, compliance, dependencies on other people)

Round 2, Scope and Done Condition (if needed):

• What does "done" look like? How will you know this worked?
• What's explicitly out of scope?
• Is there a deployment target or audience?

Round 3 (only if the task involves multiple systems, external dependencies, or scope the user hasn't fully decided):

• Clarify integration points, sequencing, or unresolved scope questions from Rounds 1-2

Read ~/.claude/skills/plan/gotchas.md for planning pitfalls to avoid.

After the interview, confirm your understanding in 2-3 sentences before proceeding.

Step 1.5: Scout Plugins (conditional)

Run for: client projects, new features, multi-system work, anything touching APIs or external services. Skip for: internal tooling, config changes, simple bug fixes, single-file edits.

When running:

Agent(subagent_type: "pr-pln-sct-plgns", model: "sonnet", prompt: "")

Include the scout's recommendations in the plan where relevant. If nothing relevant, move on.

Step 2: Research (silent)

Before writing the plan:

• Check what exists on disk (relevant directories, existing code, config files)
• Read any referenced files the user mentioned
• Check MEMORY.md for relevant project context
• If this plan is for a client project, read the client agent file at ~/.claude/agents/.md

Step 3: Write the Plan

Read references/plan-template.md for the file template and formatting rules. Save to ~/.claude/plans/.md.

Rules

1. Plan approval != build approval. When the user approves a plan, that means the plan is accepted. Still ask for explicit write approval before creating or modifying files in client projects.
2. Every phase MUST have a completion promise with a verifiable bash command. Non-negotiable.
3. Phases must be independently verifiable. Don't bundle unrelated work.
4. Keep phases small enough for a single session. If a phase would take more than 30 minutes, split it.
5. Name files and directories explicitly. Don't say "create a config file."
6. Flag dispatch candidates. Note phases that can be dispatched with /dispatch.
7. Gotchas learn from failure. When a phase fails or the user corrects your approach, write a one-line gotcha to ~/.claude/skills/plan/proposed_gotchas.md. Read existing gotchas.md and proposed_gotchas.md first to avoid duplicates. Proposed gotchas are reviewed during /sync-context. If gotchas.md exceeds 15 entries, ask Damon which to prune before merging.

After Writing

1. Show the user the plan outline (phase names + one-line descriptions), then the full plan
2. Ask: "Ready to execute, or want to adjust?"
3. Once approved, ask which reviewers to dispatch:

Dispatch reviews? Options:
  /plan-review --mode selective  [gemini | opus | skip]
  Colleague review               [gemini | opus | skip]

Dispatch both reviews based on the user's choice. Use /plan-review (now a skill with --mode support for dispatch).
