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\".</h2>\n<h1>One worktree per agent</h1>\n<p>The shared checkout belongs to the human. An agent that edits it directly races every other\nagent and every uncommitted human change. So: branch a worktree off the default branch, work\nthere, land the result through the repo's normal path, remove the worktree.</p>\n<h2>Create</h2>\n<pre><code>REPO=$(git rev-parse --show-toplevel)\nNAME=&lt;task-slug&gt;\nDEST=$(citizen worktree create \"$NAME\" \"$REPO\")\ncd \"$DEST\"\n</code></pre>\n<p>The dedicated root keeps temporary task checkouts separate from permanent clones. It defaults to\n<code>~/worktrees/&lt;repo&gt;/&lt;task&gt;</code>; <code>HARNESS_WORKTREE_ROOT</code> may replace <code>~/worktrees</code>. The helper fetches\n<code>origin</code> and branches from <code>origin/main</code>, so it starts from what is actually merged. If the repo's\ninstructions name a different base, pass <code>--base</code>; if they name a different location, follow them.\nNever create a task worktree as a sibling under the directory holding permanent repositories.</p>\n<h2>Work</h2>\n<ul>\n<li>Install dependencies in the worktree if the repo needs them per checkout; do not assume the\nshared checkout's <code>node_modules</code> or virtualenv is reachable.</li>\n<li>Run the repo's quality gate in the worktree before pushing, per <code>verification.md</code>.</li>\n<li>Never <code>cd</code> back into the shared checkout to run something \"quickly\".</li>\n</ul>\n<h2>Land</h2>\n<p>Push the branch and open a PR, or push to <code>main</code> if the repo's instructions allow it. Then:</p>\n<pre><code>citizen worktree remove \"$NAME\" \"$REPO\" --merged\n</code></pre>\n<p><code>--merged</code> deletes the local branch as well, and only once <code>gh</code> reports a merged pull request\nwhose head commit is the branch tip. A repository that squash-merges leaves the branch's own\ncommits out of the default branch, so <code>git branch -d</code> refuses work that did land; that proof is\nthe check instead. Drop <code>--merged</code> to keep the branch. Removal does not count regenerable caches\nsuch as <code>__pycache__</code> that a gate run wrote, and still refuses any other modified, untracked or\nignored entry; <code>--also-clear &lt;name&gt;</code> adds a regenerable top-level directory the built-in list\nmisses.</p>\n<h2>Things that bite</h2>\n<ul>\n<li><strong>Tooling that resolves paths against the working directory</strong> (planning frameworks, skill\nprojections) will not find its files in a worktree. If a tool halts with a missing-script\nerror, that is the guard working; run that tool from the shared checkout only.</li>\n<li><strong>Shared append-only documents</strong> (a decisions log, a changelog) are not worktree material:\ntwo agents appending in two worktrees produce a conflict at merge. Append to those on the\ndefault branch in one place.</li>\n<li><strong>Generated index files</strong> are rebuilt once at merge, never on both sides.</li>\n<li><strong>Leftover worktrees</strong> confuse <code>git status</code> and history rewrites. <code>git worktree list</code> before\nany operation that touches every branch. <code>citizen worktree audit \"$REPO\"</code> reports dirty and\nstale checkouts; a clean checkout can still contain unpublished commits, so audit branch history\nbefore removal.</li>\n</ul>\n","files":[{"path":"SKILL.md","sizeBytes":3211,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
