Docket

One list every AI tool you use can write to — Claude Code, Codex, Cursor, Warp — across every project, before the work is worth a ticket. Local-first, self-hostable, no SaaS account.

Quick start

You need: Node.js 18+ and at least one MCP host — Claude Code, Codex, Cursor, Windsurf, Claude Desktop, Zed or Warp.

npx -y @pasichdev/docket setup

That configures every host it finds on this machine and ends by telling you which ones. Then restart your agent and ask it "add a todo: buy milk" — it shows up at http://localhost:8787, a dashboard that started by itself the moment the agent connected.

Only want Claude Code, and nothing written anywhere else? claude mcp add docket -- npx -y @pasichdev/docket does just that part. Other hosts: Supported hosts.

npm install -g @pasichdev/docket        # the hook runs a command, so it needs one on PATH
docket hook install                     # then: docket hook doctor

Why

A thought that shows up mid-session is worth capturing but not worth the ceremony: a Notion template, a GitLab issue format, a ticket id you have to invent. So today it evaporates. Docket is the layer underneath all of that — work lands here at the speed an agent can type, from any tool, in any project, and graduates to Notion/GitLab/Obsidian when it's earned it.

Nobody else occupies this space, and it isn't an accident: Anthropic will not integrate Claude Code with Cursor, and Cursor will not integrate with Codex. Every vendor optimises its own closed loop. The space between the tools is structurally nobody's.

One list, many projects

Docket files every item under the project it was captured in, automatically — resolved from the git remote of wherever the agent is running. You never type it, and no agent has to remember to.

~/work/backend      claude-code, codex   ─┐
~/side/tracker      claude-code          ─┼──▶  docket  ──▶  one list, three scopes
~/side/notes        codex, warp          ─┘

• todo_list in ~/work/backend shows that project's open items, not all three projects' — compact, one line each.
• The web dashboard has a workspace switcher with per-project open counts.
• Items with no project context land under Unfiled and stay visible, never guessed at.

Using the git remote rather than the path means the same repo cloned to ~/src/backend on a laptop and /work/backend on a desktop is one workspace — which matters precisely because sync exists. Full resolution order and the .docket.json override: docs/workspaces.md.

_{Regenerate these with node docs/assets/demo-seed.mjs — it builds the workspace they show, so they stay a picture of the real dashboard rather than a staged one.}

Upgrading from 2.x

Read this before you upgrade if you have existing items.

3.0 migrates your store from data format v7 to v8 on first run, automatically. The migration itself is safe and is not the risk. Downgrading afterwards is.

docket 2.3.1 writes the store from its own v7 shape: it has never heard of the fields v8 adds, so its very first write after a reinstall silently strips them from every item. Nothing errors, and a later re-upgrade hands out fresh sequence numbers that no longer mean what your paired devices think they mean. 2.3.1 is published and cannot be patched, so 3.0 defends the only way it can — by keeping a copy of your pre-migration store:

~/.docket/todos.v7-pre-upgrade.enc

It is written once, before the first v8 write, and never overwritten. The upgrade prints its path on the run that creates it.

To go back to 2.x, restore it first:

docket restore --from-v7                     # puts the v7 store back; moves the v8 one aside
npm install -g @pasichdev/docket@2.3.1

In that order. restore --from-v7 deletes nothing — your v8 store is renamed aside, so you can come forward again later.

If you would rather have a portable copy as well, docket backup ./pre-v3.backup before upgrading gives you one that includes your identity and paired peers.

Bridges, not replaces

Docket is deliberately not where work lives forever. It's where work lands first, before anyone knows whether it deserves a ticket. Most of it doesn't and gets closed by hand; the rest graduates.

sourceUrl is the bridge in both directions. Set it whenever an item maps to something with a URL — a GitLab issue, a Notion page, an Obsidian share link, a Slack thread, a GitHub PR — and the card carries a clickable link straight back to it.

Why not just use GitHub Issues? Because an issue costs a title you have to phrase for an audience, a repo you have to pick, and labels you have to maintain — and because your Cursor session can't write one for you while you're mid-thought in a different project. Docket costs one sentence, from whichever tool you already have open. When the item turns out to matter, it becomes an issue, and sourceUrl remembers where it went.

Supported hosts

Any MCP host works — the tools are identical everywhere:

{
  "mcpServers": {
    "docket": { "command": "npx", "args": ["-y", "@pasichdev/docket"] }
  }
}

{
  "context_servers": {
    "docket": { "command": { "env": {}, "path": "npx", "args": ["-y", "@pasichdev/docket"] } }
  }
}

The one hook

Claude Code additionally gets a SessionStart hook, and only that one:

docket hook install      # writes .claude/settings.json (--global for user-wide)
docket hook doctor       # proves it fires, and reports measured latency
docket hook uninstall    # removes only the entries docket owns

When a session starts it injects the items open in that project — compact, at most 7, under 120 tokens. Nothing at all when the project has nothing open. Its whole job is continuity: you come back to a terminal and the thread is already there.

Don't want it? export DOCKET_HOOKS=off disables it immediately, without editing any config or uninstalling anything. docket hook doctor measures the real round trip and says so if it is slow enough to notice.

It fails open, always. Server not running, request timed out, malformed response, DOCKET_HOOKS=off — every one of those exits 0 and prints nothing. A tool that degrades your session when the tool itself is broken gets uninstalled, at which point it helps nobody. docket hook doctor runs the configured command for real and reports what a session would actually see, so a hook that never fires is visible rather than merely silent.

No PreToolUse, no blocking, no other hosts — the hook's only job in this release is continuity, not enforcement.

Guidance for non-Claude-Code agents

The tools work everywhere; the guidance ships as a Claude Code plugin. For any other agent, copy skills/docket/SKILL.md (everything below the --- frontmatter) into whichever file your agent reads — AGENTS.md for Codex, .cursor/rules/docket.mdc for Cursor, .windsurfrules for Windsurf, CLAUDE.md for Claude Desktop, or Warp's custom-instructions setting.

/plugin marketplace add pasichDev/docket
/plugin install docket@docket

CLI

docket list [-w <project>] [--all]          What's open, scoped like the MCP default
docket workspaces                           Projects, with open counts and last activity
docket sessions                             Agent sessions open right now, and where
docket stats | export | import              Inspection and round-tripping
docket hook install | uninstall | doctor    Claude Code SessionStart hook
docket serve | pair | devices | status      Self-hosted server & devices
docket backend use <url> | localize         Switch deployment mode
docket backup <file> | restore <file>       Encrypted full-device backup
docket web                                  Ensure the Web UI is running
docket check-update | update                Version management

docket help prints the canonical, always-current list. Full reference: docs/cli.md.

Deployment modes

Both modes install from the same package and expose the same MCP tools. Full self-hosted setup and what it deliberately doesn't do: docs/self-hosting.md.

P2P sync is deprecated as of v3.0. It still works, and nothing is removed in this release — but its 15-second pull interval means claims are advisory across it, so it cannot deliver an atomic guarantee. Self-hosted Mode is the supported multi-machine path. See docs/p2p-sync.md.

Web UI

A real-time read/write dashboard — http://localhost:8787 by default in Local Mode (override with DOCKET_WEB_PORT), or the Docket Server's own URL in Self-hosted Mode. Workspace switcher with per-project open counts, an active- sessions panel, light/dark theme, search, sort, inline edit, undo-delete, responsive mobile layout.

In Local Mode it starts itself: the first MCP client to connect spawns it detached in the background if nothing's listening yet. Updates push live over Server-Sent Events (/api/events), no polling.

Opening it from another device on your LAN (phone, tablet) requires an explicit Viewer Gate approval from the host machine first — see Security.

Security

Docket has four separate threat models (encrypted local storage, P2P sync, the LAN Viewer Gate, and self-hosted client/server traffic) — a guarantee from one does not apply to another. The basics:

• At rest: todos.json.enc and history.json.enc are AES-256-GCM encrypted with a locally generated key — protects against accidental exposure, not against someone with read access to your own user account.
• P2P sync: X25519 ECDH + HKDF-derived per-pair secrets, HMAC-signed requests with replay protection, AES-256-GCM encrypted responses.
• LAN Viewer Gate: any browser other than the host machine needs explicit human approval before it can open the dashboard; that local traffic itself is plain HTTP, not TLS (documented tradeoff, not an oversight).
• Self-hosted mode: per-device HMAC signatures with timestamp+nonce replay protection. The server is not end-to-end encrypted against its own operator.
• Updates: every release is published with Sigstore-backed npm provenance, verifiable with npm audit signatures.

Full threat model, exact primitives and limitations: docs/security.md.

Data & encryption

Authoritative data lives on this machine (~/.docket) in Local Mode, or on the Docket Server in Self-hosted Mode — either way on infrastructure you control, never a hosted account.

• todos.json.enc — the store, AES-256-GCM encrypted
• history.json.enc — the full audit log, kept off the store's write path
• key — a locally generated 256-bit key, chmod 600
• device.json — this machine's id, name, and X25519 identity keypair
• peers.json.enc — paired P2P devices and their derived sync secrets
• sessions.json — which agent sessions are open right now (plain, local-only, never synced; it holds process metadata, not content)

Set DOCKET_DATA_DIR to relocate the directory; startup refuses to silently split an existing store rather than guessing.

Backup & updating

docket backup <file> bundles the whole data directory into one password-protected file (AES-256-GCM, scrypt-derived key); docket restore writes it back, renaming what's on disk aside rather than overwriting.

docket check-update   # read-only — reports current vs. latest
docket update         # checks, confirms, installs, self-tests, rolls back on failure

Testing

npm test

Runs the full node:test suite — sync delivery and pagination, the cross-process file lock under real contention, workspace resolution and scoping, the session registry, agent-facing token budgets, and the hook's fail-open behaviour.
