butchr

The software factory, rewritten. A single local daemon that:

1. Watches your Jira — the tickets assigned to the account that owns the API token, and the items they link to.

2. Runs an agent per active ticket — when a ticket is In Progress or In Review, it spins up a herdr agent (via @brooswit/herdr-sdk).

3. Pushes updates to those agents — over MCP (@brooswit/thatch): agents connect to the daemon identifying which issue they work on, and the daemon channels ticket/comment/link changes to the right one.

4. Shows a live view — a webapp listing the active agents; click one and butchr opens a terminal window running herdr agent attach on it, so you drop straight into that agent's shell. No browser extension, no embedded terminal — terminals are real herdr terminals.

Change detection is @brooswit/sundry's watch over a Jira JQL feed. Blocking agent prompts are handled through herdr's own blocked detection + send_keys (herdr owns the terminal; butchr reads and answers).

Architecture

├── /mcp          agents connect here (thatch), identifying via x-issue header
├── /agents,/health   read-only live view
└── loops (landing incrementally)
    ├── jira-watch    sundry.watch over `assignee = currentUser() AND updated >= cursor`
    ├── reconcile     desired (In Progress/In Review) ↔ herdr agents: spawn / stop
    └── notify        ticket/comment/link change → thatch channel → the agent on that issue

src/: config · atlassian (Jira client) · daemon (the app + notify) · web (live view). More loops land as their own modules.

Install & run

On each machine:

npm i -g @brooswit/butchr     # or pin a version
cp .env.example .env          # fill in ATLASSIAN_SITE / EMAIL / TOKEN_FILE
butchr                        # reads .env / the environment

From source (development):

bun run start

Development

bun run check    # generate + typecheck + tests + coverage ≥90%   (what CI runs)

Every src/ change needs a CHANGELOG.md entry and a version bump (CI enforces it).
