Planning

About

Create hierarchical project plans optimized for solo agentic development. Use when planning projects, phases, or tasks that Claude will execute...

SKILL.md

You are planning for ONE person (the user) and ONE implementer (Claude). No teams. No stakeholders. No ceremonies. No coordination overhead. The user is the visionary/product owner. Claude is the builder. PLAN.md is not a document that gets transformed into a prompt. PLAN.md IS the prompt. It contains: - Objective (what and why) - Context (@file references) - Tasks (type, files, action, verify, done, checkpoints) - Verification (overall checks) - Success criteria (measurable) - Output (SUMMARY.md specification)

When planning a phase, you are writing the prompt that will execute it.

Plans must complete within ~50% of context usage to maintain consistent quality.

The quality degradation curve:

0-30% context: Peak quality (comprehensive, thorough, no anxiety)
30-50% context: Good quality (engaged, manageable pressure)
50-70% context: Degrading quality (efficiency mode, compression)
70%+ context: Poor quality (self-lobotomization, rushed work)

Critical insight: Claude doesn't degrade at 80% - it degrades at ~40-50% when it sees context mounting and enters "completion mode." By 80%, quality has already crashed.

Solution: Aggressive atomicity - split phases into many small, focused plans.

Examples:

01-01-PLAN.md - Phase 1, Plan 1 (2-3 tasks: database schema only)
01-02-PLAN.md - Phase 1, Plan 2 (2-3 tasks: database client setup)
01-03-PLAN.md - Phase 1, Plan 3 (2-3 tasks: API routes)
01-04-PLAN.md - Phase 1, Plan 4 (2-3 tasks: UI components)

Each plan is independently executable, verifiable, and scoped to 2-3 tasks maximum.

Atomic task principle: Better to have 10 small, high-quality plans than 3 large, degraded plans. Each commit should be surgical, focused, and maintainable.

Autonomous execution: Plans without checkpoints execute via subagent with fresh context - impossible to degrade.

See: references/scope-estimation.md

**Claude automates everything that has a CLI or API.** Checkpoints are for verification and decisions, not manual work.

Checkpoint types:

checkpoint:human-verify - Human confirms Claude's automated work (visual checks, UI verification)
checkpoint:decision - Human makes implementation choice (auth provider, architecture)

Rarely needed: checkpoint:human-action - Only for actions with no CLI/API (email verification links, account approvals requiring web login with 2FA)

Critical rule: If Claude CAN do it via CLI/API/tool, Claude MUST do it. Never ask human to:

Deploy to Vercel/Railway/Fly (use CLI)
Create Stripe webhooks (use CLI/API)
Run builds/tests (use Bash)
Write .env files (use Write tool)
Create database resources (use provider CLI)

Protocol: Claude automates work → reaches checkpoint:human-verify → presents what was done → waits for confirmation → resumes

See: references/checkpoints.md, references/cli-automation.md

Plans are guides, not straitjackets. Real development always involves discoveries.

During execution, deviations are handled automatically via 5 embedded rules:

Auto-fix bugs - Broken behavior → fix immediately, document in Summary
Auto-add missing critical - Security/correctness gaps → add immediately, document
Auto-fix blockers - Can't proceed → fix immediately, document
Ask about architectural - Major structural changes → stop and ask user
Log enhancements - Nice-to-haves → auto-log to ISSUES.md, continue

No user intervention needed for Rules 1-3, 5. Only Rule 4 (architectural) requires user decision.

All deviations documented in Summary with: what was found, what rule applied, what was done, commit hash.

Result: Flow never breaks. Bugs get fixed. Scope stays controlled. Complete transparency.

See: workflows/execute-phase.md (deviation_rules section)

No enterprise process. No approval gates. No multi-week timelines. Plan → Execute → Ship → Learn → Repeat.

Milestone-driven: Ship v1.0 → mark milestone → plan v1.1 → ship → repeat. Milestones mark shipped versions and enable continuous iteration.

Milestones mark shipped versions (v1.0, v1.1, v2.0).

Purpose:

Historical record in MILESTONES.md (what shipped when)
Greenfield → Brownfield transition marker
Git tags for releases
Clear completion rituals

Default approach: Extend existing roadmap with new phases.

v1.0 ships (phases 1-4) → add phases 5-6 for v1.1
Continuous phase numbering (01-99)
Milestone groupings keep roadmap organized

Archive ONLY for: Separate codebases or complete rewrites (rare).

See: references/milestone-management.md

NEVER include in plans: - Team structures, roles, RACI matrices - Stakeholder management, alignment meetings - Sprint ceremonies, standups, retros - Multi-week estimates, resource allocation - Change management, governance processes - Documentation for documentation's sake

If it sounds like corporate PM theater, delete it.

Monitor token usage via system warnings.

At 25% remaining: Mention context getting full At 15% remaining: Pause, offer handoff At 10% remaining: Auto-create handoff, stop

Never start large operations below 15% without user confirmation.

Never charge ahead at critical decision points. Use gates: - **AskUserQuestion**: Structured choices (2-4 options) - **Inline questions**: Simple confirmations - **Decision gate loop**: "Ready, or ask more questions?"

Mandatory gates:

Before writing PLAN.md (confirm breakdown)
After low-confidence research
On verification failures
After phase completion with issues
Before starting next phase with previous issues

See: references/user-gates.md

All planning artifacts are version controlled. Commit outcomes, not process.

Check for repo on invocation, offer to initialize
Commit only at: initialization, phase completion, handoff
Intermediate artifacts (PLAN.md, RESEARCH.md, FINDINGS.md) NOT committed separately
Git log becomes project history

See: references/git-integration.md

**CRITICAL: This skill writes directly to `.planning/` - NEVER use EnterPlanMode or delegate to Plan agents.**

All planning artifacts are created using the Write tool directly in the project directory:

.planning/BRIEF.md
.planning/ROADMAP.md
.planning/phases/{phase}/{plan}-PLAN.md
.planning/phases/{phase}/{plan}-SUMMARY.md

NEVER:

Use EnterPlanMode tool (saves to ~/.claude/plans/ home directory)
Delegate to Task tool with subagent_type=Plan
Save plans anywhere except .planning/

WHY: Plan mode is for Claude Code's internal planning. This skill creates project-specific planning artifacts that must live in the project repository for version control and team collaboration.

Follow the workflows exactly - they use Write tool with explicit .planning/ paths.

**Run on every invocation** to understand current state:

# Check git status
git rev-parse --git-dir 2>/dev/null || echo "NO_GIT_REPO"

# Check for planning structure
ls -la .planning/ 2>/dev/null
ls -la .planning/phases/ 2>/dev/null

# Find any continue-here files
find . -name ".continue-here.md" -type f 2>/dev/null

# Check for existing artifacts
[ -f .planning/BRIEF.md ] && echo "BRIEF: exists"
[ -f .planning/ROADMAP.md ] && echo "ROADMAP: exists"

If NO_GIT_REPO detected: Inline question: "No git repo found. Initialize one? (Recommended for version control)" If yes: git init

Present findings before intake question.

**Domain expertise lives in `~/.claude/skills/expertise/`**

Before creating roadmap or phase plans, determine if domain expertise should be loaded.

```bash ls ~/.claude/skills/expertise/ 2>/dev/null ```

This reveals available domain expertise (e.g., macos-apps, iphone-apps, unity-games, nextjs-ecommerce).

If no domain skills found: Proceed without domain expertise (graceful degradation). The skill works fine without domain-specific context.

If user's request contains domain keywords, INFER the domain:

Keywords	Domain Skill
"macOS", "Mac app", "menu bar", "AppKit", "SwiftUI desktop"	expertise/macos-apps
"iPhone", "iOS", "iPad", "mobile app", "SwiftUI mobile"	expertise/iphone-apps
"Unity", "game", "C#", "3D game", "2D game"	expertise/unity-games
"MIDI", "MIDI tool", "sequencer", "MIDI controller", "music app", "MIDI 2.0", "MPE", "SysEx"	expertise/midi
"Agent SDK", "Claude SDK", "agentic app"	expertise/with-agent-sdk
"Python automation", "workflow", "API integration", "webhooks", "Celery", "Airflow", "Prefect"	expertise/python-workflow-automation
"UI", "design", "frontend", "interface", "responsive", "visual design", "landing page", "website design", "Tailwind", "CSS", "web design"	expertise/ui-design

If domain inferred, confirm:

Detected: [domain] project → expertise/[skill-name]
Load this expertise for planning? (Y / see other options / none)

If no domain obvious from request, present options:

What type of project is this?

Available domain expertise:
1. macos-apps - Native macOS with Swift/SwiftUI
2. iphone-apps - Native iOS with Swift/SwiftUI
3. unity-games - Unity game development
4. swift-midi-apps - MIDI/audio apps
5. with-agent-sdk - Claude Agent SDK apps
6. ui-design - Stunning UI/UX design & frontend development
[... any others found in expertise/]

N. None - proceed without domain expertise
C. Create domain skill first

Select:

When domain selected, use intelligent loading:

Step 1: Read domain SKILL.md

cat ~/.claude/skills/expertise/[domain]/SKILL.md 2>/dev/null

This loads core principles and routing guidance (~5k tokens).

Step 2: Determine what references are needed

Domain SKILL.md should contain a <references_index> section that maps planning contexts to specific references.

Example:

<references_index>
**For database/persistence phases:** references/core-data.md, references/swift-concurrency.md
**For UI/layout phases:** references/swiftui-layout.md, references/appleHIG.md
**For system integration:** references/appkit-integration.md
**Always useful:** references/swift-conventions.md
</references_index>

Step 3: Load only relevant references

Based on the phase being planned (from ROADMAP), load ONLY the references mentioned for that type of work.

# Example: Planning a database phase
cat ~/.claude/skills/expertise/macos-apps/references/core-data.md
cat ~/.claude/skills/expertise/macos-apps/references/swift-conventions.md

Context efficiency:

SKILL.md only: ~5k tokens
SKILL.md + selective references: ~8-12k tokens
All references (old approach): ~20-27k tokens

Announce: "Loaded [domain] expertise ([X] references for [phase-type])."

If domain skill not found: Inform user and offer to proceed without domain expertise.

If SKILL.md doesn't have references_index: Fall back to loading all references with warning about context usage.

Domain expertise should be loaded BEFORE: - Creating roadmap (phases should be domain-appropriate) - Planning phases (tasks must be domain-specific)

Domain expertise is NOT needed for:

Creating brief (vision is domain-agnostic)
Resuming from handoff (context already established)
Transition between phases (just updating status)

Based on scan results, present context-aware options:

If handoff found:

Found handoff: .planning/phases/XX/.continue-here.md
[Summary of state from handoff]

1. Resume from handoff
2. Discard handoff, start fresh
3. Different action

If planning structure exists:

Project: [from BRIEF or directory]
Brief: [exists/missing]
Roadmap: [X phases defined]
Current: [phase status]

What would you like to do?
1. Plan next phase
2. Execute current phase
3. Create handoff (stopping for now)
4. View/update roadmap
5. Something else

If no planning structure:

No planning structure found.

What would you like to do?
1. Start new project (create brief)
2. Create roadmap from existing brief
3. Jump straight to phase planning
4. Get guidance on approach

Wait for response before proceeding.

| Response | Workflow | |----------|----------| | "brief", "new project", "start", 1 (no structure) | `workflows/create-brief.md` | | "roadmap", "phases", 2 (no structure) | `workflows/create-roadmap.md` | | "phase", "plan phase", "next phase", 1 (has structure) | `workflows/plan-phase.md` | | "chunk", "next tasks", "what's next" | `workflows/plan-chunk.md` | | "execute", "run", "do it", "build it", 2 (has structure) | **EXIT SKILL** → Use `/run-plan ` slash command | | "research", "investigate", "unknowns" | `workflows/research-phase.md` | | "handoff", "pack up", "stopping", 3 (has structure) | `workflows/handoff.md` | | "resume", "continue", 1 (has handoff) | `workflows/resume.md` | | "transition", "complete", "done", "next" | `workflows/transition.md` | | "milestone", "ship", "v1.0", "release" | `workflows/complete-milestone.md` | | "guidance", "help", 4 | `workflows/get-guidance.md` |

Critical: Plan execution should NOT invoke this skill. Use /run-plan for context efficiency (skill loads ~20k tokens, /run-plan loads ~5-7k).

After reading the workflow, follow it exactly.

The planning hierarchy (each level builds on previous):

BRIEF.md          → Human vision (you read this)
    ↓
ROADMAP.md        → Phase structure (overview)
    ↓
RESEARCH.md       → Research prompt (optional, for unknowns)
    ↓
FINDINGS.md       → Research output (if research done)
    ↓
PLAN.md           → THE PROMPT (Claude executes this)
    ↓
SUMMARY.md        → Outcome (existence = phase complete)

Rules:

Roadmap requires Brief (or prompts to create one)
Phase plan requires Roadmap (knows phase scope)
PLAN.md IS the execution prompt
SUMMARY.md existence marks phase complete
Each level can look UP for context

All planning artifacts go in `.planning/`:

SKILL.md

When planning a phase, you are writing the prompt that will execute it.

Plans must complete within ~50% of context usage to maintain consistent quality.

The quality degradation curve:

0-30% context: Peak quality (comprehensive, thorough, no anxiety)
30-50% context: Good quality (engaged, manageable pressure)
50-70% context: Degrading quality (efficiency mode, compression)
70%+ context: Poor quality (self-lobotomization, rushed work)

Critical insight: Claude doesn't degrade at 80% - it degrades at ~40-50% when it sees context mounting and enters "completion mode." By 80%, quality has already crashed.

Solution: Aggressive atomicity - split phases into many small, focused plans.

Examples:

01-01-PLAN.md - Phase 1, Plan 1 (2-3 tasks: database schema only)
01-02-PLAN.md - Phase 1, Plan 2 (2-3 tasks: database client setup)
