- aac/act
act is an agent task tracker distributed as a Claude Code marketplace plugin with a bundled binary and MCP server so coding agents can claim and close work via git-merged JSON ops.
About
act is a Claude Code marketplace that ships a single-binary agent task tracker stored as append-only JSON inside a nested .act/ git repo, plus skills and MCP access for autonomous loops. Install it when human-centric issue trackers are overhead and you want agents to ready, claim, close, and push tracker state with plain git semantics. The README positions the plugin as the canonical install path that bundles the binary, workflow skill, and MCP server.
- Append-only JSON ops in nested git repo at .act/
- Atomic claim, act next, and act finish verbs for agent loops
- Bundled MCP server mirrors CLI commands
- Act-Id commit trailers correlate code commits with closed issues

Who is it for?
Developers who let Claude Code or other MCP agents drive a lightweight git-backed issue queue in each repo.
