worktree-session skillA
worktree-session is agent-read markdown (skill) from clickety-clacks/tightbeam: Your own clone is the isolation boundary when many agents edit one repo — clone into your workdir, never adopt a repo you did not create, push so the remote holds the record, reconcile before building, never destroy work that is not yours, cleanup. Use at the start of and throughout any assignment that touches a repository..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified before it reaches your agent: the main file against the SHA-256 recorded here, the others against the git hashes of its source commit. The deterministic audit below grades the latest version, and the same checks always give the same file the same grade.
What the file says
# Repo session Other agents edit the same repository at the same time. Your own clone is the isolation boundary. Codex exposes the engineering review commands `/review-branch` and `/review-commit`. 1. **Clone your own copy, into your own workdir.** `git clone <remote> <workdir>/<branch-name>`, then work on a branch named for the work. Do NOT `git worktree add` against a repo you did not create, and do not adopt a repo you found sitting on the box. A shared repo puts every agent's branches in one namespace, so one agent's `fetch --prune` or branch delete reaches into another's live checkout; and its disk belongs to a session that can retire out from under you, taking every checkout hanging off it. Disk is cheap. A checkout that vanishes mid-assignment is not. 2. **Push, so the remote holds the record.** Your workdir is durable; your checkout is not the record. Commit and push at every natural stopping point, not once at the end. Work that exists only in a local directory is one cleanup away from gone, and the agent that deletes it will not know it was yours. 3. A repo below your session root does not announce its conventions: its `AGENTS.md` …

How to install
mdr add clickety-clacks/tightbeam/worktree-session@git:20260905.fcf177fmdr add clickety-clacks/tightbeam/worktree-session@sha256:de661823f69bfb26Pin to a label to follow the author's releases, or to a sha256 for exact bytes. Either way the resolved hash is written to mdr.lock, and mdr install fetches those bytes again and checks them, so it installs them exactly or fails.
