# ⛔ Create Plugin — STOP AND READ

**DO NOT ACT ON ASSUMPTIONS. Read this file first.**

This is a structured workflow command for creating a new plugin in a Claude Code marketplace.

Your FIRST and ONLY action right now: **Execute the TodoWrite below.**

> **Self-Evolving Skill**: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

## ⛔ MANDATORY FIRST ACTION: TodoWrite Initialization

**YOUR FIRST ACTION MUST BE the TodoWrite call below.**

DO NOT:

- ❌ Create any directories before TodoWrite
- ❌ Read marketplace.json before TodoWrite
- ❌ Ask questions before TodoWrite
- ❌ Jump to any phase without completing Step 0

### Step 0.1: Detect Marketplace Root

Before executing TodoWrite, verify you're in a marketplace directory:

```bash
/usr/bin/env bash << 'PREFLIGHT_EOF'
# Check for marketplace.json in cwd
if [ -f ".claude-plugin/marketplace.json" ]; then
  echo "✅ Marketplace detected: $(jq -r .name .claude-plugin/marketplace.json)"
else
  echo "❌ Not a marketplace directory. Run from a marketplace root."
  exit 1
fi
PREFLIGHT_EOF
```

### Step 0.2: Execute MANDATORY TodoWrite

**Execute TodoWrite NOW with this template:**

```
TodoWrite with todos:

- "[Plugin] Phase 0: Detect marketplace root" | in_progress
- "[Plugin] Phase 0: Interactive prompts (name, category, components)" | pending
- "[Plugin] Phase 0: Confirm plugin doesn't exist" | pending
- "[Plugin] Phase 1: Skill → plugin-structure (scaffold)" | pending
- "[Plugin] Phase 1: Create plugin directory + plugin.json" | pending
- "[Plugin] Phase 1: Skill → implement-plan-preflight (ADR)" | pending
- "[Plugin] Phase 2: Skill → skill-architecture (if has-skills)" | pending
- "[Plugin] Phase 2: Skill → hook-development (if has-hooks)" | pending
- "[Plugin] Phase 2: Skill → command-development (if has-commands)" | pending
- "[Plugin] Phase 2: Skill → agent-development (if has-agents)" | pending
- "[Plugin] Phase 2: Agent → skill-reviewer (if skills created)" | pending
- "[Plugin] Phase 3: Add to marketplace.json" | pending
- "[Plugin] Phase 3: Run validate-plugins.mjs" | pending
- "[Plugin] Phase 3: Skill → code-hardcode-audit" | pending
- "[Plugin] Phase 3: Agent → plugin-validator" | pending
- "[Plugin] Phase 4: Git commit (conventional format)" | pending
- "[Plugin] Phase 4: Push to remote" | pending
- "[Plugin] Phase 4: Skill → semantic-release" | pending
```

**After TodoWrite completes, proceed to Phase 0 section below.**

## Phase 0: Discovery & Validation

Detect marketplace root, gather plugin name/category/components via interactive prompts, confirm the plugin does not already exist.

**Detailed steps**: [Phase 0 Reference](./references/phase0-discovery.md)

### Phase 0 Gate

- [ ] Marketplace root detected (`.claude-plugin/marketplace.json` exists)
- [ ] Plugin name collected (kebab-case, no spaces)
- [ ] Category selected
- [ ] Components selected (skills/hooks/commands/agents)
- [ ] Plugin directory does NOT exist
- [ ] Plugin NOT in marketplace.json

---

## Phase 1: Scaffold Plugin

1. **Invoke `Skill(plugin-dev:plugin-structure)`** -- directory & manifest patterns
2. **Create plugin directory** with component subdirs based on user selections
3. **Generate `plugin.json`** using marketplace version
4. **Invoke `Skill(itp:implement-plan-preflight)`** -- creates ADR + Design Spec + diagrams

**Detailed steps**: [Phase 1 Reference](./references/phase1-scaffold.md)

### Phase 1 Gate

- [ ] Plugin directory exists: `plugins/$PLUGIN_NAME/`
- [ ] plugin.json created with marketplace version
- [ ] ADR exists: `docs/adr/$ADR_ID.md`
- [ ] Design spec exists: `docs/design/$ADR_ID/spec.md`
- [ ] Both diagrams in ADR (Before/After + Architecture)

---

## Phase 2: Component Creation (Conditional)

Execute ONLY the skills for components the user selected:

| Component | Skill Invocation                        | Then                                    |
| --------- | --------------------------------------- | --------------------------------------- |
| Skills    | `Skill(plugin-dev:skill-architecture)`  | Spawn `Task(plugin-dev:skill-reviewer)` |
| Hooks     | `Skill(plugin-dev:hook-development)`    | --                                      |
| Commands  | `Skill(plugin-dev:command-development)` | --                                      |
| Agents    | `Skill(plugin-dev:agent-development)`   | --                                      |

**Detailed steps**: [Phase 2 Reference](./references/phase2-components.md)

### Phase 2 Gate

- [ ] All selected components created
- [ ] If skills: skill-reviewer agent completed review
- [ ] Files follow plugin-dev patterns

---

## Phase 3: Registration & Validation

1. **Add plugin to `marketplace.json`** (include `hooks` field if hooks exist)
2. **Run
