run parallel claude code writers, such as PR owners or dependency workers, as desktop sessions in their own worktrees, with sub-agents as the fallback.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
how a claude code orchestrator runs parallel writers, such as PR owners or dependency workers, each in its own worktree. codex does not use this skill: it runs parallel writers as new threads - the app refuses `start_session` in any turn the user's own message didn't start, including turns a writer's message or note wakes. so start every writer your calling skill plans in the turn that invoked it - `start_session` with `initiation: "user_asked"`, `use_worktree: true` and a short `name` - a session's worktree can start from a stale local branch, so each prompt names the writer's base and tells it to reset its new branch to the freshly fetched base before it starts - add your session id from `get_session` with `self` to each prompt, and tell the writer to send its result there with `SendMessage` before it ends its turn. the app's notes on writers' turns arrive only once every writer is idle and quote 400 characters, so read them as session status, never as results - follow up with `SendMessage` to the writer's `local_…` session id - for a writer that comes up later, or when `start_session` fails, use the first that works: …

How to install
mdr add nicholas-greenwood/agentic-engineering-skills/claude-parallel-writers@sha256:5a3ba9e4e027dcedThe line at the top of this page pins the label git:20261103.0e28fa2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
