# backlog

backlog keeps Claude Code tasks across sessions and links them to the built-in task flow. Use it when another agent must resume unfinished work.

## What it does

backlog gives Claude Code a durable task layer that survives a session change. Its skills cover backlog views, goal breakdowns, standups, cleanup, task specs, implementation, and handoff notes. The `task-planner` agent can inspect a codebase, split a goal around dependencies, and write specs for larger items.

Hooks connect the plugin to Claude Code task events: a session can show pending work, created tasks can be copied into the persistent backlog, and completed tasks can be closed there. MCP tools handle filters, task status, annotations, attached markdown documents, and archives. Project data is separated automatically when the plugin is used normally; standalone mode requires `TASKDATA` to be set.

## 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 backlog@claude-community
```

## When to use it
- keep tasks across Claude Code sessions
- split a goal into dependent work items
- write a task spec before implementation
- hand work over to the next session
- filter blocked, active, or ready tasks

## Example prompts
- Use `/backlog:tasks` to show the current backlog and find overdue work.
- Run `/backlog:plan` to split this goal into tasks with dependencies and specs.
- Use `/backlog:handoff` to record progress for the next Claude Code session.

Persistent, cross-session task management for Claude Code. Tasks survive sessions so work started by one agent can be picked up by another.

Built on [@backloghq/agentdb](https://github.com/backloghq/agentdb) — typed schemas, auto-increment IDs, virtual filters, blob storage. Pure TypeScript, zero native dependencies.

## Install

```
/plugin marketplace add backloghq/backlog
/plugin install backlog@backloghq-backlog
```

### From source

```bash
git clone https://github.com/backloghq/backlog.git
cd backlog && npm install && npm run build
claude --plugin-dir /path/to/backlog
```

### Standalone MCP server

Add to your project's `.claude/settings.json`:

```json
{
  "mcpServers": {
    "backlog": {
      "command": "node",
      "args": ["/path/to/agent-teams-task-mcp/dist/index.js"],
      "env": {
        "TASKDATA": "/path/to/task-data"
      }
    }
  }
}
```

## Skills

| Skill | Description |
|-------|-------------|
| `/backlog:tasks` | Show the current backlog — pending, active, blocked, overdue tasks |
| `/backlog:plan` | Break down a goal into tasks with dependencies, priorities, and specs |
| `/backlog:standup` | Daily standup — done, in progress, blocked, up next |
| `/backlog:refine` | Groom the backlog — fix vague tasks, missing priorities, broken deps, stale items |
| `/backlog:spec` | Write a spec document for a task before implementation |
| `/backlog:implement` | Pick up a task, read its spec, implement it, mark done |
| `/backlog:handoff` | Prepare for next session — annotate progress, stop active tasks, summarize state |

## Agent

The `task-planner` agent can be auto-invoked by Claude when someone needs to plan work. It reads the codebase, decomposes goals into tasks with dependencies, and writes specs for complex items.

## Hooks

| Event | What it does |
|-------|-------------|
| `SessionStart` | Shows pending task count when a session begins |
| `TaskCreated` | Syncs Claude's built-in tasks to the persistent backlog |
| `TaskCompleted` | Marks the matching backlog task as done when Claude completes a built-in task |
| `SubagentStart` | Auto-assigns unassigned pending tasks to the spawned agent |

## Tools (MCP)

Tools for full task lifecycle management:

| Tool | Description |
|------|-------------|
| `task_list` | Query tasks with filter syntax. Returns JSON array with all fields. |
| `task_count` | Count tasks matching a filter. Same syntax as task_list. |
| `task_add` | Create a new pending task. Only description required; all other fields optional. |
| `task_log` | Record already-completed work directly in completed status. |
| `task_modify` | Partial-update one or more tasks matching a filter. Only provided fields change. |
| `task_duplicate` | Copy an existing task with optional field overrides. |
| `task_done` | Mark a task as completed with end timestamp. |
| `task_delete` | Soft-delete a task. Restorable with task_undo. Use task_purge to permanently remove. |
| `task_annotate` | Add a timestamped note. Use task_doc_write for longer content. |
| `task_denotate` | Remove an annotation by exact text match. |
| `task_start` | Mark a task as actively being worked on. Visible in +ACTIVE queries. |
| `task_stop` | Stop working on a task. Returns it to pending status. |
| `task_undo` | Undo the most recent operation. Can be called repeatedly. |
| `task_info` | Get full JSON details for a single task by ID or UUID. |
| `task_import` | Bulk-create tasks from a JSON array. Atomic batch operation. |
| `task_purge` | Permanently remove a deleted task. Irreversible. |
