Agentpack

Repo-native task continuity for AI coding agents.

Coding agents forget. Agentpack gives them the task state they need to continue.

Here it is live. Session 1: Claude Code investigates a flaky test and records what it learns through the Agentpack MCP tools. Session 2, next day, empty context: the agent loads the task state and picks up exactly where the first session stopped — no re-investigation:

Prefer to poke at it by hand? The same flow driven from the CLI is in docs/DEMOS.md.

Every session ends the same way: the context window gets compacted, the chat closes, the task waits until tomorrow. The next session starts from zero — re-reading files, rediscovering decisions, retrying approaches that already failed.

Agentpack keeps a small, reviewable task ledger in .agentpack/ inside your repo. Connected agents record durable state as they work — the goal, decisions, dead ends, verification evidence, checkpoints — and the next session loads it back and continues. That next session can be the same agent after compaction, a different client, or you returning next week.

• Local-first. Plain files in your repo. No cloud, no telemetry, no network calls.
• Agent-oriented. A local MCP server plus generated project instructions (AGENTS.md, CLAUDE.md, Cursor rules) tell agents when to load and record state.
• Human-friendly. The same state is available through the CLI for inspection, debugging, and manual handoff.

Quick start

Requires Node.js >= 20.

npm install -g agentpack-cli

cd path/to/your/repo
agentpack init                     # once per repo
agentpack install claude --write   # per client: codex | claude | cursor | claude-desktop

Restart or reconnect the coding-agent client. From then on the agent loads Agentpack context at session start, records durable decisions, sources, and evidence while working, and checkpoints meaningful progress.

Run agentpack doctor to verify the setup, and agentpack resume --preset agent --query "<topic>" to inspect the task state yourself.

See docs/INTEGRATIONS.md for client-by-client setup, including what each installer writes and why.

How it works

1. At session start, the agent loads compact Agentpack context: the current Task Passport, recent checkpoints, decisions, and reviewed source conclusions.
2. While working, it records durable state — decisions worth keeping, approaches that failed, verification evidence — and caches reviewed source conclusions with file hashes so unchanged files don't need re-reading.
3. At a coherent boundary, it creates a checkpoint with status, next actions, and git state.
4. The next session — any MCP-connected agent — continues from that state instead of rebuilding it from chat history.

The ledger is task-scoped: a Task Passport carries the goal, status, constraints, write scope, next actions, and verification for the current task, with an explicit lifecycle (start, park, switch, finalize) for handoffs. An optional task gate (native Claude Code, Codex, and Cursor hooks plus a client-neutral pre-commit hook) warns — or in block mode, stops — when edits bypass the active task.

Context is budgeted: resume output is compressed under a rough token estimate, so agents get the useful state back, not a pile of history.

When it helps

• The context window is compacted mid-task and the next turn needs the state back.
• You start a fresh chat or session on an ongoing task.
• You switch between Claude Code, Cursor, Codex, or another MCP client.
• You return to a refactor or bugfix days later.
• Another agent — or a teammate's agent — continues from your checkpoint.
• You split one session across parts of a monorepo (api/, frontend/, cron/) with short scoped tasks, and the task gate keeps the agent from drifting outside the folder the current task owns.

A side effect: agents spend fewer tokens re-reading unchanged files and re-explaining old decisions.

Security posture

• Zero runtime dependencies, exact dev dependencies, committed lockfile, ignore-scripts=true.
• No telemetry and no network calls during normal CLI or MCP operation.
• Best-effort redaction of secret-looking values in stored context and handoff output.
• Releases are published from GitHub Actions with npm provenance (Trusted Publisher, no long-lived tokens); verify with npm audit signatures.

See SECURITY.md for the full policy.

Contributing / local development

Clone the repo and use Node 20+:

npm ci --ignore-scripts
npm test
npm run mcp:smoke
node dist/src/agentpack.js --help

This repo uses Agentpack on itself through MCP — docs/DOGFOOD.md describes the working protocol, docs/SETUP.md the full setup, and docs/RELEASING.md the release process.
