## What it does

The plugin runs background subagents inside dedicated git worktrees to keep the primary working tree clean. Each subagent follows a five-step lifecycle: analyzing project conventions, building a plan, implementing edits incrementally, running test checks, and committing changes. Real-time status tracking relies on a `SubagentStop` hook running `bin/update-registry.sh` to update `.claude/agents/registry.json`.

The `/agent` command family handles lifecycle tasks. You can monitor logs, inspect inline diffs, merge finished branches with `/agent merge <id>`, or recover broken tasks with `/agent resume <id>`. While flags like `--effort` and `--max-turns` are logged as metadata, `--model` directly controls which model (`haiku`, `sonnet`, or `opus`) drives the worker.

Git and Node.js are mandatory. Because worktrees skip gitignored files by default, tasks that depend on `.env` or local secrets fail unless you declare them inside a `.worktreeinclude` file at the repository root.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install agent-manager@claude-community
```

## When to use it
- isolate background agent tasks using git worktrees
- resume interrupted or failed runs without restarting from zero
- spawn batches of parallel tasks with `/agent batch`
- merge completed agent changes into the main branch

## Example prompts
- /agent --model sonnet "refactor auth module to use JWT"
- /agent batch "add unit tests for payment service" "document public endpoints"
- /agent resume agent-42

# Claude Agent Manager

A Claude Code plugin for spawning and managing autonomous background agents with persistent state across sessions.

## What it does

- **Spawn** background agents that work in isolated git worktrees
- **Track** agent status with a persistent registry (`.claude/agents/registry.json`)
- **Auto-detect completion** via hooks — registry updates in real-time when agents finish
- **Resume** stopped or failed agents from where they left off
- **Merge** completed agent work back into your main branch
- **Monitor** agent activity with logs, diffs, and watch mode
- **Learn** from previous tasks via persistent worker memory

## Install

```bash
claude plugin install agent-manager
```

When enabling, you'll be prompted for optional defaults:
- **Default model** — `haiku`, `sonnet`, or `opus` (leave empty to inherit from session)
- **Default effort** — `low`, `medium`, `high`, or `max` (leave empty for `high`)

Or test locally:

```bash
claude --plugin-dir /path/to/claude-agent-manager
```

### Requirements

- **Git** — agents work in isolated git worktrees
- **Node.js** — used by the hook script (always available since Claude Code runs on Node)
- No other external dependencies

## Commands

### Core

| Command | Description |
|---------|-------------|
| `/agent "task"` | Spawn a new background agent |
| `/agent list` | Show all agents and their status |
| `/agent switch <id>` | View details of a specific agent |
| `/agent stop <id>` | Stop a running agent |
| `/agent merge <id>` | Merge a completed agent's branch |
| `/agent history` | Show full agent history |
| `/agent clean` | Remove finished agents and worktrees |

### Recovery

| Command | Description |
|---------|-------------|
| `/agent resume <id>` | Resume a stopped/failed agent on its existing branch |
| `/agent retry <id>` | Re-spawn a failed agent with the same task from scratch |

### Inspection

| Command | Description |
|---------|-------------|
| `/agent diff <id>` | Quick inline diff preview of agent's changes |
| `/agent logs <id>` | Summarized activity log of what the agent did |
| `/agent stats` | Lifetime stats — total spawned, success rate, etc. |

### Advanced

| Command | Description |
|---------|-------------|
| `/agent batch "task1" "task2"` | Spawn multiple agents in parallel |
| `/agent note <id> "text"` | Attach a note to an agent |
| `/agent watch <id>` | Poll a running agent until completion |
| `/agent rebase <id>` | Rebase agent branch onto latest main |
| `/agent export <id>` | Export changes as a `.patch` file |

### Templates

Spawn with a pre-defined template:

```
/agent --template api "add user profile endpoint"
```

Templates are stored in `.claude/agents/templates/` as JSON files:

```json
{
  "name": "api",
  "description": "API endpoint template",
  "verifyCommand": "npm test",
  "commitFormat": "feat(api): {description}"
}
```

Required fields: `name`, `description`. Optional: `verifyCommand` (overrides Phase 4 auto-detection), `commitFormat` (overrides conventional commit format).

### Spawn Flags

| Flag | Values | Description |
|------|--------|-------------|
| `--model` | `haiku`, `sonnet`, `opus` | Choose which model the agent uses |
| `--effort` | `low`, `medium`, `high`, `max` | Effort level metadata (worker runs at `high`) |
| `--color` | `red`, `blue`, `green`, `yellow`, `purple`, `orange`, `pink`, `cyan` | Visual color for agent identification |
| `--max-turns` | `<number>` | Max turns metadata (worker default: 200) |
| `--template` | `<name>` | Use a pre-defined template |

> **Note:** `--model` is the only flag that changes agent behavior at runtime (via the Agent tool's `model` parameter). `--effort` and `--max-turns` are stored in the registry for tracking but the worker subagent always uses `effort: high` and `maxTurns: 200` from its definition. `--color` sets the agent's display color.

**Examples:**

```
/agent --model sonnet "refactor the auth module"
/agent --model haiku --color blue "add JSDoc comments to utils/"
/agent --max-turns 50 "quick formatting fix"
