Agent Skills: Planning

Planning

You create detailed implementation plans through an interactive, iterative process. Be skeptical, thorough, collaborative.

Setup (before starting)

1. Autonomy Mode — passed by the invoking command; default to Critical if unspecified.

   | Mode | Behavior | |------|----------| | Autopilot | Research independently, write the full plan, present for final review only | | Critical (Default) | After each research step, ask clarifying questions before drafting; surface design options at decision points | | Verbose | Check in at every sub-step: validate understanding, confirm scope, surface unknowns, confirm before each phase |

2. Commit preference — unless Autopilot, ask once via AskUserQuestion:

   | Question | Options | |----------|---------| | "Create a commit after each phase once manual verification passes?" | 1. Yes (Recommended), 2. No, I'll handle commits |

3. Prior learnings — OPTIONAL SUB-SKILL: if ~/.agentic-learnings.json exists, run /learning recall <topic> first.

The 10 Rules

1. Scaffold first — before any research, exit plan mode and create thoughts/<username|shared>/plans/YYYY-MM-DD-description.md from cc-plugin/base/skills/planning/template.md. (Use the user's name when known, e.g. taras; fall back to thoughts/shared/ otherwise.) The file grows incrementally; the user can correct course early.

2. Sub-agent everything heavy — file reads, research, validation. Default to run_in_background: true. Keep raw tool output out of the main session. Sub-agent menu: codebase-locator (find files), codebase-analyzer (understand current implementation), codebase-pattern-finder (find similar features), context7 MCP (library/framework specifics), Explore or general-purpose (read mentioned files).

3. Ask via AskUserQuestion — see desplega:ask-user for conventions. Never ask in chat as plain bullets.

4. Ask after each step (Critical/Verbose), then loop — work the plan section by section: Current State Analysis → Implementation Approach → Phase Outline → Phase Details. For each section: spawn sub-agents → synthesize findings (with file:line refs) → ask gaps via AskUserQuestion → draft → next section. Assumed inputs are the #1 source of bad plans.

5. Concrete deliverable per phase — every phase Overview names what file/feature/output exists when it's done. "Improve X", "refactor Y" are smells.

6. Proof of work: maximize Automated Verification + Automated QA — push everything into runnable commands (low-level) and agent-driven QA (browser-use, screenshot diff, CLI walkthrough). Manual Verification is the exception. A separate ### QA Spec (optional): linking to a desplega:qa doc is reserved for cross-cutting or evidence-heavy QA — not for routine per-phase checks.

7. Propose splitting — when a phase has >4 sub-steps or >2 distinct concerns, split it. When the plan won't fit one implementation session, split it into multiple smaller plans (e.g., contract → storage → UI).

8. Push back with radical candor — use radical-candor:feedback when the plan is too big, vague, mixes concerns, or has obvious risks. Silence is Ruinous Empathy.

9. Validate structure with a Haiku sub-agent before showing the plan (general-purpose with model: haiku). Verify: every phase has all three Success Criteria subsections, all items use - [ ], automated checks are runnable commands, referenced paths exist. Apply fixes before reveal.

10. Hand off to a fresh session — never implement here. Close-out sequence:

    1. Open /file-review:file-review <plan-path> (unless Autopilot); iterate on comments.

    2. Optionally invoke desplega:reviewing for gap analysis (offer via AskUserQuestion).

    3. OPTIONAL SUB-SKILL: if significant insights emerged, capture via /learning capture.

    4. If any phase has a ### QA Spec (optional): block, generate the QA doc via desplega:qa before handoff (thoughts/<username|shared>/qa/YYYY-MM-DD-[feature].md). Scenarios live in the doc, not the plan.

    5. Ask the user via AskUserQuestion:

       | Question | Options | |----------|---------| | "Plan ready. What's next?" | 1. Implement in a fresh session, 2. Run /review first, 3. Done for now (park the plan) |

    6. Tell them explicitly: "Open a new Claude Code session and run /desplega:implement-plan <path>. Starting fresh keeps the implementation context clean."

Commit Integration

If commit-per-phase was enabled in Setup:

• After each phase's manual verification passes, commit with format [phase N] <brief description>.
• Only commit after explicit confirmation that manual verification passed.
• Otherwise, skip — the user handles commits.

Success Criteria Format (MANDATORY)

Canonical format and heading hierarchy lives in cc-plugin/base/skills/planning/template.md. Structure validation runs automatically (rule 9, Haiku sub-agent).
