Derives the parent/child chain from git ancestry, rebases each branch onto its new parent, and force-pushes with a lease. Works with plain git; uses a forge CLI only to retarget PR/MR bases when one is available. Also known as <code>klaussy-restack</code>.</h2>\n<p>Rebase a stack of dependent branches so each one sits on top of its parent again, then push the stack. <code>klaussy restack</code> does the git mechanics: it maps the chain from ancestry and reflogs, rebases bottom-up with <code>--onto</code>, verifies, and pushes with a lease. Your job is the two decisions it can't make: confirming the chain, and resolving conflicts.</p>\n<p><strong>If the <code>klaussy</code> command isn't found, run it as <code>python3 -m klaussy &lt;command&gt;</code></strong> (<code>python -m klaussy</code> on Windows, where <code>python3</code> is usually absent) <strong>before falling back any further</strong> — the package is often installed with only its script directory off PATH. Use the fallback named for that step when that fails too, and say which one you used: a fallback answers a narrower question than the command it stands in for.</p>\n<p>If <code>klaussy</code> isn't on PATH (the command isn't found), follow <code>.agents/skills/fastapi-restack/manual.md</code> instead; it's the same procedure by hand.</p>\n<p><strong>First, check for a stack tool.</strong> If the repo uses Graphite, git-town, spr or ghstack, or the host carries a native stack (see the forge commands below), use that tool's own restack command so its metadata stays consistent, and say which you found.</p>\n<h2>1. Map and confirm</h2>\n<p>Run <code>klaussy restack plan</code>, which resolves the base itself (pass <code>--base</code> to override). It fetches, then prints the chain bottom-up, which branches already landed in the base, who authored the commits, and any line that needs you:</p>\n<ul>\n<li><strong>BLOCKED</strong> (dirty tree): let the user commit or stash. Never restack over uncommitted work.</li>\n<li><strong>ASK</strong> (two branches on one commit): ask which is the parent.</li>\n<li><strong>NOTE</strong> (a fork): each child rebases separately; say so.</li>\n</ul>\n<p>Show the user the chain and confirm it before anything is rewritten; a wrong parent drops or duplicates commits. If the stack holds commits by someone else, get explicit confirmation before force-pushing over their work. Optionally cross-check the chain against the forge's request bases; if they disagree, surface it rather than picking one.</p>\n<h2>2. Rebase</h2>\n<p>Run <code>klaussy restack run --chain &lt;confirmed chain&gt;</code> with the chain exactly as confirmed. It records every branch's tip first, so <code>klaussy restack undo</code> puts everything back until you push.</p>\n<p>Exit code 2 means a conflict. For each file it names:</p>\n<ol>\n<li>Show the user both sides of the hunk.</li>\n<li>Resolve it by understanding the change. Never reach for <code>--ours</code> / <code>--theirs</code> to make it go away.</li>\n<li><code>git add</code> the file, then <code>git rebase --continue</code>, then <code>klaussy restack run --continue</code>.</li>\n</ol>\n<p>If a conflict is genuinely ambiguous, run <code>klaussy restack undo</code> and hand it back with the specifics. A half-rebased stack is worse than stopping.</p>\n<h2>3. Verify</h2>\n<p>Run <code>klaussy restack verify</code>. Every branch should keep its own commit count. Lines marked <code>!</code> are commits whose content changed in the move, which is expected where you resolved a conflict and a red flag anywhere else. Read those before pushing.</p>\n<h2>4. Retarget, then push</h2>\n<p>If a request's parent changed or landed, retarget its base with the forge commands below, before the push where the forge allows, so it never briefly shows its parent's commits as its own.</p>\n<h3>Forge commands (GitHub)</h3>\n<p><code>origin</code> points at GitHub, so the <code>gh</code> CLI is the adapter. Confirm a flag with <code>gh &lt;command&gt; --help</code> before running one you haven't used in this repo; CLI interfaces drift between versions.</p>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Need</th>\n<th style=\"text-align: left\">Command</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Read a ticket</td>\n<td style=\"text-align: left\"><code>gh issue view &lt;n&gt; --comments</code></td>\n</tr>\n<tr>\n<td style=\"text-align: left\">Open a request</td>\n<td style=\"text-align: left\"><code>gh pr create --base &lt;branch&gt; --title &lt;title&gt; --body-file &lt;file&gt;</code></td>\n</tr>\n<tr>\n<td style=\"text-align: left\">Request status</td>\n<td style=\"text-align: left\"><code>gh pr view &lt;n&gt; --json state,mergeable,reviewDecision,baseRefName</code></td>\n</tr>\n<tr>\n<td style=\"text-align: left\">CI status</td>\n<td style=\"text-align: left\"><code>gh pr checks &lt;n&gt;</code>, then <code>gh run view &lt;run-id&gt; --log-failed</code> on a failure</td>\n</tr>\n<tr>\n<td style=\"text-align: left\">Retarget a request</td>\n<td style=\"text-align: left\"><code>gh pr edit &lt;n&gt; --base &lt;branch&gt;</code></td>\n</tr>\n</tbody>\n</table>\n<p><code>{owner}/{repo}</code> are placeholders <code>gh</code> fills from the current repo, leave them literal.</p>\n<p><strong>GitHub has native stacks</strong>, driven by the <code>gh-stack</code> extension. <code>gh extension list</code> says whether it's installed. If it isn't, <strong>offer to install it</strong> — <code>gh extension install github/gh-stack</code>, one command, no repo changes — and say what it buys before asking: a stack map and layer navigation on every request page, plus cascading rebase when the base moves. Ask rather than installing unprompted, since it touches the user's <code>gh</code> setup and not this repo, but do ask; silently settling for bare chained bases hands back a worse result than the one command would have. Declining is a fine answer and the fallback below still works.</p>\n<p>The extension is in public preview, so check <code>gh stack &lt;command&gt; --help</code> before relying on a flag.</p>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Need</th>\n<th style=\"text-align: left\">Command</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Link requests that already exist into a stack</td>\n<td style=\"text-align: left\"><code>gh stack link --base &lt;branch&gt; &lt;branch-or-pr&gt; &lt;branch-or-pr&gt; ...</code></td>\n</tr>\n<tr>\n<td style=\"text-align: left\">Track a carved chain locally</td>\n<td style=\"text-align: left\"><code>gh stack init --base &lt;branch&gt; &lt;branch&gt; ...</code></td>\n</tr>\n<tr>\n<td style=\"text-align: left\">Push the tracked chain and open or update its requests</td>\n<td style=\"text-align: left\"><code>gh stack submit</code></td>\n</tr>\n<tr>\n<td style=\"text-align: left\">See the stack</td>\n<td style=\"text-align: left\"><code>gh stack view</code></td>\n</tr>\n<tr>\n<td style=\"text-align: left\">Cascading rebase after the base moved</td>\n<td style=\"text-align: left\"><code>gh stack rebase</code></td>\n</tr>\n<tr>\n<td style=\"text-align: left\">Fetch, rebase, push, and sync in one pass</td>\n<td style=\"text-align: left\"><code>gh stack sync</code></td>\n</tr>\n</tbody>\n</table>\n<p>Arguments run bottom-up, nearest the base first. Two constraints decide whether a stack is available at all: <strong>every branch must live in this repo</strong> (cross-fork stacks aren't supported), and the extension has to be installed.</p>\n<p><code>link</code> and <code>init</code> are two different entry points and the difference shows up later. <code>link</code> stacks requests that already exist and leaves nothing behind locally, so a later <code>gh stack rebase</code> needs <code>gh stack checkout &lt;stack-number&gt;</code> first to pick the stack back up. <code>init</code> registers the branches locally up front and <code>submit</code> then opens the requests itself, which means the bodies are its own — write them with <code>gh pr edit &lt;n&gt; --body-file</code> afterwards if they have to say something specific.</p>\n<p>Without it, chained <code>--base</code> targets still give reviewers a per-layer diff, and GitHub often offers to convert an eligible chain into a stack — a banner on the request, or \"Add to stack\" behind the stack icon. Say which route you took.</p>\n<p>A missing, unauthenticated or nonexistent CLI is not a failure here. Print what's left instead: each branch, its new parent, and the one field to change. Never ask the user to install a hosting CLI to finish a rebase.</p>\n<p>Then run <code>klaussy restack push</code>. It force-pushes bottom-up with <code>--force-with-lease --force-if-includes</code>, never pushes <code>master</code>, and stops at the first refusal. A refused lease means someone else pushed: fetch and look. Never fall back to a bare <code>--force</code>.</p>\n<h2>5. Report</h2>\n<p>Report the stack's new shape, the pre-restack tips from the plan output (the recovery path now that the push is done), and anything left to retarget by hand. Say plainly that only what CI re-runs is verified; a clean rebase is not a passing test.</p>\n<h2>Rules</h2>\n<ul>\n<li>Git is the source of truth for topology. A forge CLI may enrich or confirm the chain; it never gates the rebase.</li>\n<li>Do not squash, reword or reorder while restacking. A restack moves commits; changing them at the same time makes the diff impossible to review.</li>\n<li>Never delete branches as part of a restack, even ones that already landed.</li>\n</ul>\n<h2>When NOT to use</h2>\n<ul>\n<li>A single branch based on <code>master</code> is behind — that's a plain <code>git rebase origin/master</code>, no stack machinery needed.</li>\n<li>The user wants to land the stack (merge each request in order) — different task, different risks.</li>\n<li>The branches live in a fork or you lack push rights — the rebase will succeed locally and the push will fail; check first.</li>\n<li>The stack is shared and teammates have unpushed work on it — coordinate before rewriting, force-with-lease can't protect what it hasn't seen.</li>\n</ul>\n","files":[{"path":"manual.md","sizeBytes":6419,"isText":true},{"path":"SKILL.md","sizeBytes":8062,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
