# Install plugin-dev + hookify as brain-meta plugins (brain v1.2)

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Install Anthropic-verified plugins `plugin-dev` (#17) + `hookify` (#18) as `meta` category brain plugins per [docs/brain-plugin-routing.md §5.1](../../brain-plugin-routing.md), bumping brain to v1.2 with routing.md v1.1 (new task classes: plugin creation, hook creation).

**Architecture:** Both plugins already in `~/.claude/plugins/marketplaces/claude-plugins-official/plugins/` (marketplace HEAD `00679aef889e`), absent from `~/.claude/plugins/cache/` and `enabledPlugins`. Path 2 install: `cp -r` from marketplaces → cache (avoid duplicate `git clone`; marketplace is already a fresh clone). 6-artifact atomic install per plugin: cache + user-level enable + user-level manifest + brain plugins-manifest + brain settings-fragment + routing.md row. Marketplaces.json unchanged (marketplace already registered). 3 commits: plugin-dev, hookify, version bump v1.1→v1.2.

**Tech Stack:** Bash (`cp -r`, jq), markdown, JSON, git atomic commits.

**Routing reference:** [docs/brain-plugin-routing.md §5.1](../../brain-plugin-routing.md) — 10-step install for `meta` category.

**Marketplace state verified at planning time:**
- Marketplace `claude-plugins-official` HEAD = `00679aef889efe36bb0389f81d70b6229a2013ee`
- `plugin-dev` source: `~/.claude/plugins/marketplaces/claude-plugins-official/plugins/plugin-dev/`
- `hookify` source: `~/.claude/plugins/marketplaces/claude-plugins-official/plugins/hookify/`
- Both have `.claude-plugin/plugin.json` with Anthropic author
- Neither in `~/.claude/plugins/cache/`, neither in `enabledPlugins`, neither in `installed_plugins.json`

**Cache version convention:** Phase 0 used `00679aef889e` (marketplace HEAD short-sha) as version subdir. We follow same convention for consistency: `cache/claude-plugins-official/<plugin>/00679aef889e/`.

## File Structure

| File | Action | Tasks |
|---|---|---|
| `~/.claude/plugins/cache/claude-plugins-official/plugin-dev/00679aef889e/` | CREATE (cp -r from marketplace) | Task 1 |
| `~/.claude/plugins/cache/claude-plugins-official/hookify/00679aef889e/` | CREATE (cp -r from marketplace) | Task 2 |
| `~/.claude/settings.json` | MODIFY (add 2 keys to enabledPlugins) | Task 1, Task 2 |
| `~/.claude/plugins/installed_plugins.json` | MODIFY (add 2 entries) | Task 1, Task 2 |
| `user-level-files/plugins-manifest.json` | MODIFY (add 2 entries with target+category) | Task 1, Task 2 |
| `user-level-files/settings-fragment.json` | MODIFY (add 2 keys to enabledPlugins) | Task 1, Task 2 |
| `docs/brain-plugin-routing.md` | MODIFY (bump v1.0→v1.1: +2 §2.1, +2 §4.2, +2 §3.1 task classes) | Task 1, Task 2 |
| `.brain-version` | MODIFY (v1.1 → v1.2 + new sha) | Task 3 |
| `manifest.json` | MODIFY (version → brain-v1.2) | Task 3 |
| `CLAUDE.md` | MODIFY (version line v1.1→v1.2) | Task 3 |
| `CHANGELOG.md` | MODIFY (+v1.2 entry above v1.1) | Task 3 |

**Note on user-level vs brain-only files:** User-level files (`~/.claude/...`) are runtime state on this machine, NOT in brain repo. They get edited but only brain repo files get committed. The 3 atomic commits only touch files in `c:/моя/проекты/claude-brain/`.

---

### Task 1: Install plugin-dev

**Files:**
- Create: `~/.claude/plugins/cache/claude-plugins-official/plugin-dev/00679aef889e/` (full copy from marketplace)
- Modify: `~/.claude/settings.json` (add `"plugin-dev@claude-plugins-official": true` to enabledPlugins)
- Modify: `~/.claude/plugins/installed_plugins.json` (add entry under key `plugin-dev@claude-plugins-official`)
- Modify: `user-level-files/plugins-manifest.json` (add entry with target="user-level", category="meta")
- Modify: `user-level-files/settings-fragment.json` (add key to enabledPlugins)
- Modify: `docs/brain-plugin-routing.md` (bump v1.0→v1.1: +row in §2.1, +row in §4.2, +row in §3.1 «Создание plugin'а»)

- [ ] **Step 1: Pre-state RED test**

Run:
```bash
ls -d "$HOME/.claude/plugins/cache/claude-plugins-official/plugin-dev" 2>/dev/null && echo EXISTS || echo ABSENT
jq -e '.enabledPlugins | has("plugin-dev@claude-plugins-official")' "$HOME/.claude/settings.json"
```
Expected: `ABSENT`, `false`

- [ ] **Step 2: Install in cache via cp -r**

Run:
```bash
mkdir -p "$HOME/.claude/plugins/cache/claude-plugins-official/plugin-dev"
cp -r "$HOME/.claude/plugins/marketplaces/claude-plugins-official/plugins/plugin-dev" "$HOME/.claude/plugins/cache/claude-plugins-official/plugin-dev/00679aef889e"
ls "$HOME/.claude/plugins/cache/claude-plugins-official/plugin-dev/00679aef889e/"
```
Expected: directory contains `.claude-plugin`, `agents`, `commands`, `skills`, `LICENSE`, `README.md`.

- [ ] **Step 3: Enable in user-level settings.json**

Edit `~/.claude/settings.json` → add line in `enabledPlugins` block:
```json
  "plugin-dev@claude-plugins-official": true,
```
(Use Edit tool with exact context to insert after existing entries.)

- [ ] **Step 4: Verify GREEN — user-level enable**

Run:
```bash
jq -e '.enabledPlugins."plugin-dev@claude-plugins-official"' "$HOME/.claude/settings.json"
```
Expected: `true`.

- [ ] **Step 5: Add entry to user-level installed_plugins.json**

Edit `~/.claude/plugins/installed_plugins.json` → add new key `"plugin-dev@claude-plugins-official"` with array value:
```json
"plugin-dev@claude-plugins-official": [
  {
    "scope": "user",
    "installPath": "C:\\Users\\Administrator\\.claude\\plugins\\cache\\claude-plugins-official\\plugin-dev\\00679aef889e",
    "version": "00679aef889e",
    "installedAt": "2026-05-11T15:00:00.000Z",
    "lastUpdated": "2026-05-11T15:00:00.000Z",
    "gitCommitSha": "00679aef889efe36bb0389f81d70b6229a2013ee",
    "installMethod": "manual-cp-from-marketplace-Path2"
  }
]
```
(Use actual current ISO timestamp for installedAt/lastUpdated — not literal placeholder. Bash `date -u -Iseconds` for value.)

- [ ] **Step 6: Add entry to brain `user-level-files/plugins-manifest.json`**

Edit brain manifest — add inside `"plugins": {`:
```json
"plugin-dev@claude-plugins-official": [
  {
    "scope": "user",
    "installPath": "C:\\Users\\Administrator\\.claude\\plugins\\cache\\claude-plugins-official\\plugin-dev\\00679aef889e",
    "version": "00679aef889e",
    "installedAt": "<SAME ISO TIMESTAMP AS STEP 5>",
    "lastUpdated": "<SAME ISO TIMESTAMP AS STEP 5>",
    "gitCommitSha": "00679aef889efe36bb0389f81d70b6229a2013ee",
    "installMethod": "manual-cp-from-marketplace-Path2",
    "target": "user-level",
    "category": "meta"
  }
]
```

- [ ] **Step 7: Add key to brain `user-level-files/settings-fragment.json`**

Edit brain settings-fragment → add to `enabledPlugins`:
```json
"plugin-dev@claude-plugins-official": true,
```

- [ ] **Step 8: Update `docs/brain-plugin-routing.md` — bump v1.0 → v1.1**

Three coordinated edits:

**8a. §2.1 реестр — add row** (after claude-code-setup):
```markdown
| **plugin-dev** | `anthropics/claude-plugins-official` | `meta` | создание нового plugin'а в brain'е (агенты, команды, hooks, MCP integration); тест-bed для будущих своих brain плагинов | каждодневная UI/code работа |
```

**8b. §3.1 routing-table — add row** (after «Анализ что ещё поставить»):
```markdown
| Создание нового **plugin'а** для brain (agents/commands/hooks/MCP) | `plugin-dev` | прямое создание через файлы `.claude-plugin/plugin.json` + skills если plugin тривиальный (1 skill, без агентов) | guided plugin scaffolding с best practices Anthropic |
```

**8c. §4.2 — update statuses** (change «shortlist (not installed)» → «installed v1.2»):
```markdown
| #17 | `plugin-dev` | `meta` | installed brain v1.2 (manual-cp-from-marketplace-Path2) |
```

**8d. Update version header** (top of file):
```markdown
# Brain Plugin Routing Rules (v1.1)
```

**8e. История версий** — добавить запись v1.1 ВЫШЕ существующей v1.0:
```markdown
- **v1.1 от 2026-05-11** — Installed brain-meta plugins #17 plugin-dev + #18 hookify. Added 2 rows in §2.1, 2 rows in §3.1 (new task classes: plugin creation, hook creation), updated statuses in §4.2.
```

- [ ] **Step 9: Verify GREEN — all 4 brain artifacts**

Run:
```bash
cd "c:/моя/проекты/claude-brain"
jq -e '.plugins."plugin-dev@claude-plugins-official"[0] | (.target == "user-level" and .category == "meta")' user-level-files/plugins-manifest.json
jq -e '.enabledPlugins."plugin-dev@claude-plugins-official"' user-level-files/settings-fragment.json
grep -c "plugin-dev" docs/brain-plugin-routing.md
grep -c "^# Brain Plugin Routing Rules (v1.1)" docs/brain-plugin-routing.md
```
Expected: `true`, `true`, ≥3 (in 3 sections), `1`.

- [ ] **Step 10: Commit atomic**

```bash
cd "c:/моя/проекты/claude-brain"
git add user-level-files/plugins-manifest.json user-level-files/settings-fragment.json docs/brain-plugin-routing.md
git commit -m "$(cat <<'EOF'

)"
```
Expected: 3 files changed.

### Task 2: Install hookify

**Files:** parallel structure to Task 1 — substitute `plugin-dev` → `hookify`.

- [ ] **Step 1: Pre-state RED test**

Run:
```bash
ls -d "$HOME/.claude/plugins/cache/claude-plugins-official/hookify" 2>/dev/null && echo EXISTS || echo ABSENT
jq -e '.enabledPlugins | has("hookify@claude-plugins-official")' "$HOME/.claude/settings.json"
```
Expected: `ABSENT`, `false`

- [ ] **Step 2: Install in cache via cp -r**

Run:
```bash
mkdir -p "$HOME/.claude/plugins/cache/claude-plugins-official/hookify"
cp -r "$HOME/.claude/plugins/marketplaces/claude-plugins-official/plugins/hookify" "$HOME/.claude/plugins/cache/claude-plugins-official/hookify/00679aef889e"
ls "$HOME/.claude/plugins/cache/claude-plugins-official/hookify/00679aef889e/"
```
Expected: directory contains `.claude-plugin`, `agents`, `commands`, `core`, `examples`, `hooks`, `matchers`, `skills`, `utils`, `LICENSE`, `README.md`.

- [ ] **Step 3: Enable in user-level settings.json**

Edit `~/.claude/settings.json` → add in `enabledPlugins`:
```json
  "hookify@claude-plugins-official": true,
```

- [ ] **Step 4: Verify GREEN**

```bash
jq -e '.enabledPlugins."hookify@claude-plugins-official"' "$HOME/.claude/settings.json"
```
Expected: `true`.

- [ ] **Step 5: Add entry to user-level installed_plugins.json**

```json
"hookify@claude-plugins-official": [
  {
    "scope": "user",
    "installPath": "C:\\Users\\Administrator\\.claude\\plugins\\cache\\claude-plugins-official\\hookify\\00679aef889e",
    "version": "00679aef889e",
    "installedAt": "<CURRENT ISO via date -u -Iseconds>",
    "lastUpdated": "<SAME ISO>",
    "gitCommitSha": "00679aef889efe36bb0389f81d70b6229a2013ee",
    "installMethod": "manual-cp-from-marketplace-Path2"
  }
]
```

- [ ] **Step 6: Add entry to brain plugins-manifest.json**

```json
"hookify@claude-plugins-official": [
  {
    "scope": "user",
    "installPath": "C:\\Users\\Administrator\\.claude\\plugins\\cache\\claude-plugins-official\\hookify\\00679aef889e",
    "version": "00679aef889e",
    "installedAt": "<SAME ISO AS STEP 5>",
    "lastUpdated": "<SAME ISO AS STEP 5>",
    "gitCommitSha": "00679aef889efe36bb0389f81d70b6229a2013ee",
    "installMethod": "manual-cp-from-marketplace-Path2",
    "target": "user-level",
    "category": "meta"
  }
]
```

- [ ] **Step 7: Add key to brain settings-fragment.json**

```json
"hookify@claude-plugins-official": true,
```

- [ ] **Step 8: Update routing.md**

**8a. §2.1 — add row** (after plugin-dev row):
```markdown
| **hookify** | `anthropics/claude-plugins-official` | `meta` | создание нового hook'а в brain'е from conversation patterns; complement к 10 ручным .py hook'ам в `user-level-files/hooks/` | каждодневная работа |
```

**8b. §3.1 routing-table — add row** (after plugin-dev creation row):
```markdown
| Создание нового **hook'а** в brain (PreToolUse/PostToolUse/Stop/SessionStart/UserPromptSubmit) | `hookify` | прямой Edit .py файла в `user-level-files/hooks/` если простой port существующего паттерна, или hook тривиален | guided hook generation by analyzing conversation patterns |
```

**8c. §4.2 — update status for #18:**
```markdown
| #18 | `hookify` | `meta` | installed brain v1.2 (manual-cp-from-marketplace-Path2) |
```

**8d. Update version header**:
```markdown
# Brain Plugin Routing Rules (v1.1)
```
(Already updated in Task 1 step 8d — verify still says v1.1.)

**8e. История версий** — update v1.1 entry to mention hookify too (or leave Task 1's wording which already mentions both #17+#18; no change needed if Task 1 entry covers both).

- [ ] **Step 9: Verify GREEN**

```bash
cd "c:/моя/проекты/claude-brain"
jq -e '.plugins."hookify@claude-plugins-official"[0] | (.target == "user-level" and .category == "meta")' user-level-files/plugins-manifest.json
jq -e '.enabledPlugins."hookify@claude-plugins-official"' user-level-files/settings-fragment.json
grep -c "hookify" docs/brain-plugin-routing.md
jq '.plugins | keys | length' user-level-files/plugins-manifest.json
```
Expected: `true`, `true`, ≥3, `8` (was 6, +2).

- [ ] **Step 10: Commit atomic**

```bash
cd "c:/моя/проекты/claude-brain"
git add user-level-files/plugins-manifest.json user-level-files/settings-fragment.json docs/brain-plugin-routing.md
git commit -m "$(cat <<'EOF'
feat(brain-plugins): install hookify as meta plugin

Anthropic-verified plugin from claude-plugins-official marketplace (HEAD

### Task 3: Bump brain v1.1 → v1.2

**Files:**
- Modify: `.brain-version`
- Modify: `manifest.json:version`
- Modify: `CLAUDE.md` line «**Версия:** brain-v1.1 от 11.05.2026»
- Modify: `CHANGELOG.md` (add v1.2 entry above v1.1)

- [ ] **Step 1: Get current HEAD sha (after Task 2 commit)**

```bash
cd "c:/моя/проекты/claude-brain"
git rev-parse HEAD
```
Записать SHA (это `hookify` commit SHA, base для v1.2 marker).

- [ ] **Step 2: Write .brain-version**

```
brain-v1.2
sha: <SHA_FROM_STEP_1>
```

- [ ] **Step 3: Bump manifest.json version**

Edit `manifest.json` line: `"version": "brain-v1.1"` → `"version": "brain-v1.2"`.

- [ ] **Step 4: Bump CLAUDE.md version line**

Edit: `**Версия:** brain-v1.1 от 11.05.2026` → `**Версия:** brain-v1.2 от 11.05.2026`.

- [ ] **Step 5: Add CHANGELOG entry v1.2 above v1.1**

```markdown
## brain-v1.2 — 2026-05-11

### Added
- Installed brain-meta plugin **#17 plugin-dev** (Anthropic, marketplace `claude-plugins-official` HEAD `00679aef889e`). Toolkit для создания plugin'ов с агентами, командами, hooks, MCP integration. Closes shortlist «Brain-specific must-add» part 1/2.
- Installed brain-meta plugin **#18 hookify** (Anthropic, same marketplace). Tool для создания hook'ов by analyzing conversation patterns. Complement к 10 ручным .py hook'ам. Closes shortlist «Brain-specific must-add» part 2/2.
- `docs/superpowers/plans/2026-05-11-install-plugin-dev-hookify.md` — implementation plan.
- `docs/brain-plugin-routing.md` v1.0 → v1.1: 2 новых row в §2.1, 2 row в §3.1 (новые классы задач: «создание plugin'а», «создание hook'а»), 2 status update в §4.2.

### Changed
- `user-level-files/plugins-manifest.json` — 6 → 8 entries (plugin-dev + hookify added with target=user-level, category=meta).
- `user-level-files/settings-fragment.json` — 6 → 8 entries in `enabledPlugins`.
- `CLAUDE.md` brain root — version `brain-v1.1` → `brain-v1.2`.
- `manifest.json` — `version` bumped to `brain-v1.2`.

### Notes
- Both plugins installed via `cp -r` from `~/.claude/plugins/marketplaces/...` (not separate git clone) — marketplace was already cloned, this is more efficient than Phase 0 method.
- shortlist «Brain-specific must-add» (recommender's gap finding) now fully closed.

## brain-v1.1 — 2026-05-11
```

- [ ] **Step 6: Verify all v1.2**

```bash
cd "c:/моя/проекты/claude-brain"
cat .brain-version
jq -r '.version' manifest.json
grep "^\*\*Версия:\*\*" CLAUDE.md
grep -c "^## brain-v1.2" CHANGELOG.md
```
Expected: `brain-v1.2` + sha, `brain-v1.2`, `**Версия:** brain-v1.2 от 11.05.2026`, `1`.

- [ ] **Step 7: Commit atomic (D11-style — version + changelog atomic)**

```bash
cd "c:/моя/проекты/claude-brain"
git add .brain-version manifest.json CLAUDE.md CHANGELOG.md
git commit -m "$(cat <<'EOF'
chore(brain-version): bump v1.1 → v1.2 (plugin-dev + hookify installed)

Atomic bump. Brain-meta plugins #17 plugin-dev and #18 hookify now
installed, registered in routing.md v1.1, snapshotted in manifest +
settings-fragment. Brain-specific must-add shortlist closed.

)"
```

---

### Task 4: Final verification + push

- [ ] **Step 1: git log review**

```bash
cd "c:/моя/проекты/claude-brain"
git log --oneline -5
```
Expected (reverse-chrono):
1. `chore(brain-version): bump v1.1 → v1.2 (plugin-dev + hookify installed)`
2. `feat(brain-plugins): install hookify as meta plugin`
3. `feat(brain-plugins): install plugin-dev as meta plugin`
4. `chore(brain-version): bump v1.0 → v1.1 (plugin routing)` (previous)

- [ ] **Step 2: Cross-file consistency**

```bash
cd "c:/моя/проекты/claude-brain"
diff <(jq -S '.plugins | keys' user-level-files/plugins-manifest.json) <(jq -S '.enabledPlugins | keys' user-level-files/settings-fragment.json) && echo MATCH
jq '.plugins | keys | length' user-level-files/plugins-manifest.json
```
Expected: `MATCH`, `8`.

- [ ] **Step 3: User-level vs brain consistency**

```bash
diff <(jq -S '.enabledPlugins | keys' "$HOME/.claude/settings.json") <(jq -S '.enabledPlugins | keys' user-level-files/settings-fragment.json) && echo MATCH
```
Expected: `MATCH` (user-level and brain enabledPlugins now identical).

- [ ] **Step 4: Routing.md sanity**

```bash
grep -c "^## §" docs/brain-plugin-routing.md
wc -l docs/brain-plugin-routing.md
grep -c "plugin-dev\|hookify" docs/brain-plugin-routing.md
grep "^# Brain Plugin Routing Rules" docs/brain-plugin-routing.md
```
Expected: `7`, lines should grow modestly (251 + ~6 new rows ≈ 257-260), `plugin-dev|hookify` ≥6 (≥3 each in §2.1, §3.1, §4.2), version line shows `v1.1`.

- [ ] **Step 5: Tree clean + invoke verification-before-completion**

```bash
git status
```
Expected: `nothing to commit, working tree clean`.

Then invoke `superpowers:verification-before-completion` skill for final gate per economy 0%.

- [ ] **Step 6: Push to origin/main**

```bash
git push origin main
```
Expected: 3 new commits pushed (Task 1, Task 2, Task 3).

## Self-Review

### Spec coverage (against [routing.md §5.1](../../brain-plugin-routing.md))

| §5.1 step | Task 1 step | Task 2 step | Covered? |
|---|---|---|---|
| 1 (Marketplace check) | implicit (verified at planning, already present) | implicit | ✓ |
| 1a (Marketplace add) | N/A (not new) | N/A | ✓ |
| 2 (Install в cache) | Task 1 Step 2 | Task 2 Step 2 | ✓ |
| 3 (Enable settings.json) | Task 1 Step 3 | Task 2 Step 3 | ✓ |
| 4 (User-level manifest) | Task 1 Step 5 | Task 2 Step 5 | ✓ |
| 5 (Brain plugins-manifest) | Task 1 Step 6 | Task 2 Step 6 | ✓ |
| 6 (Brain marketplaces) | N/A (no new marketplace) | N/A | ✓ |
| 7 (Brain settings-fragment) | Task 1 Step 7 | Task 2 Step 7 | ✓ |
| 8 (Update routing.md) | Task 1 Step 8 | Task 2 Step 8 | ✓ |
| 9 (Verify in new session) | NOT directly possible in this session; partial verify via jq | partial | partial — Skill tool visibility verifies only in next chat |
| 10 (Commit atomic) | Task 1 Step 10 | Task 2 Step 10 | ✓ |

**§5.1 step 9 limitation:** Skill tool's plugin list is constant per conversation. Even after enabling, `Skill('plugin-dev:...')` won't be callable until next chat. This is a known Claude Code limitation noted in PSR R11.4. Verification via jq/grep on brain artifacts is sufficient for this session; full Skill-tool verification on next chat.

### Placeholder scan

- `<SAME ISO TIMESTAMP AS STEP 5>` in Task 1 Step 6 / Task 2 Step 6 — explicit cross-reference, not a placeholder. Engineer must use same value as captured in Step 5. If executed, must be filled with real ISO timestamp before commit.
- `<SHA_FROM_STEP_1>` in Task 3 Step 2 — same: explicit cross-reference to Task 3 Step 1 output.
- `<CURRENT ISO via date -u -Iseconds>` in Task 2 Step 5 — instruction to use `date -u -Iseconds` output, not literal placeholder.

No "TBD", "TODO", "implement later", "Similar to Task N" violations. Task 2 explicitly repeats structure (not refers to Task 1) per "No Placeholders" rule.

### Type consistency

- `target: "user-level"` — used consistently in Task 1 Step 6 and Task 2 Step 6.
- `category: "meta"` — used consistently in same steps.
- `installMethod: "manual-cp-from-marketplace-Path2"` — used consistently across Task 1 Step 5/6 and Task 2 Step 5/6.
- Plugin keys with `@claude-plugins-official` suffix — consistent in all references.
- `00679aef889e` (cache version subdir) and `00679aef889efe36bb0389f81d70b6229a2013ee` (gitCommitSha) — short vs full SHA. **Consistent:** short 12-char for cache subdir (matches Phase 0 convention from skill-creator); full 40-char for gitCommitSha (verifiability).

Чисто.

## Execution Handoff

Plan complete and saved to [docs/superpowers/plans/2026-05-11-install-plugin-dev-hookify.md](../plans/2026-05-11-install-plugin-dev-hookify.md).

Two execution options:

**1. Subagent-Driven (recommended)** — fresh subagent per task, two-stage review.

**2. Inline Execution** — execute in current session via `superpowers:executing-plans`.

Per economy 0% (no subagent abuse for trivial procedural tasks) and given 4 well-scoped tasks operating on a verified §5.1 procedure — **Inline Execution** recommended.

Which approach?
