worktree-per-agent skillA
worktree-per-agent is agent-read markdown (skill) from jakeselby/agent-harness: Isolate an agent's work in its own git worktree branched off the default branch, so two agents never land conflicting changes on the shared checkout. Use at the start of any implementation task in a repo where others may also be working, and whenever a repo's instructions say "work in a worktree"..
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 against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# One worktree per agent The shared checkout belongs to the human. An agent that edits it directly races every other agent and every uncommitted human change. So: branch a worktree off the default branch, work there, land the result through the repo's normal path, remove the worktree. ## Create ```bash REPO=$(git rev-parse --show-toplevel) NAME=<task-slug> DEST=$(harness worktree create "$NAME" "$REPO") cd "$DEST" ``` The dedicated root keeps temporary task checkouts separate from permanent clones. It defaults to `~/worktrees/<repo>/<task>`; `HARNESS_WORKTREE_ROOT` may replace `~/worktrees`. The helper fetches `origin` and branches from `origin/main`, so it starts from what is actually merged. If the repo's instructions name a different base, pass `--base`; if they name a different location, follow them. Never create a task worktree as a sibling under the directory holding permanent repositories. ## Work - Install dependencies in the worktree if the repo needs them per checkout; do not assume the shared checkout's `node_modules` or virtualenv is reachable. - Run the repo's quality gate in the worktree before pushing, per `verification.md`. …

How to install
mdr add jakeselby/agent-harness/worktree-per-agent@git:20260923.097bdb0mdr add jakeselby/agent-harness/worktree-per-agent@sha256:ecc84239503c04f4Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
