--- name: utm-submit description: Submit the current UTM change as a pull request to github.com/utmapp/UTM. Ensures /utm-review has run, then either updates an existing PR (squashing each new edit into the commit that owns it and force-pushing) or opens a new PR (gathering issue links and a human-testing attestation). Use this when the user wants to submit, open, update, or push a UTM pull request, or runs /utm-submit. --- # utm-submit Agent-neutral instructions — follow them with whatever tools your agent provides (Claude Code, Codex, OpenCode, Antigravity, …). This is the canonical copy; the per-agent entries under `.claude/commands/`, `.opencode/command/`, etc. just point here. Turn the current change into a clean pull request against `utmapp/UTM`. Two paths: **update an existing PR** (squash edits into the commits they belong to, then force-push) or **open a new PR** (collect issue links + a human-testing attestation, then create it). Read `CONTRIBUTING.md` and `AGENTS.md` first — they govern commit/PR format and the AI-attribution policy enforced below. If you were invoked with an argument, treat it as a PR number or URL to update. ## Step 1 — Confirm the change was reviewed `/utm-submit` must never run on un-reviewed changes. Determine whether `/utm-review` was run on the *current* changes, in this order: 1. If you already ran `/utm-review` earlier in this session against the current changes, proceed. 2. Otherwise read `"$(git rev-parse --git-dir)/utm-review-marker"` and recompute the pending-diff hash exactly as utm-review did, then compare to `diff_hash`: ```sh { git rev-parse HEAD; git diff "$(git merge-base HEAD origin/main)"...HEAD; git diff HEAD; } | git hash-object --stdin ``` If it matches the marker's `diff_hash`, the current changes were reviewed (possibly in an earlier session or by another agent) — proceed, and say so. If the marker exists but the hash differs, the code was edited after review — treat as un-reviewed. 3. Otherwise ask the user: *"I can't confirm /utm-review ran on the current changes. How do you want to proceed?"* — offer: **Run /utm-review now** (recommended; run that workflow, then continue), **I've already reviewed it previously** (continue), **Cancel**. Do not silently skip this gate. ## Step 2 — Locate the repo, branch, and any existing PR ```sh git remote -v # find the remote pointing at utmapp/UTM branch=$(git rev-parse --abbrev-ref HEAD) ``` - **Never submit from the default branch.** If `branch` is `main` (or otherwise tracks the upstream default), stop and ask the user to move the work onto a feature branch first (`git switch -c component/short-description`) — you cannot open a `main → main` PR. - This workflow uses GitHub's `gh` CLI for everything that talks to GitHub. **If `gh` is not installed or not authenticated**, tell the user and offer to set it up: `brew install gh` then `gh auth login` (the login is interactive — have the user run it themselves in their terminal). If they decline, fall back to the manual paths noted in Steps 3a/3b. - Detect an existing open PR for this branch (or honor a PR number/URL you were given): ```sh gh pr view "$branch" --repo utmapp/UTM --json number,url,state,baseRefName,headRefName 2>/dev/null ``` An open PR → **Step 3a (update)**. No PR → **Step 3b (new)**. ## Step 3a — Update an existing PR (squash, then force-push) UTM does **not** keep "address review feedback" commits. Every edit belongs in the commit that introduced the lines it touches. The change history within a single PR must stay clean. 1. **Express the update as working-tree changes on top of the PR's published commits.** If you committed the update locally, undo just those commits so their content returns to the working tree, leaving HEAD at the published PR tip: ```sh git reset "$(git rev-parse --abbrev-ref --symbolic-full-name @{u})" # remote tracking ref of this branch ``` Now `git diff HEAD` is the full set of edits to fold in, and the commits in `base..HEAD` (base = `git merge-base HEAD origin/main`) are exactly the PR's commits. 2. **Save a recovery point** before rewriting history: `git branch utm-submit-backup/$branch` (or note `git rev-parse HEAD`). 3. **Assign each chunk to the commit that owns it.** Walk the hunks of `git diff HEAD` (use `git diff -U0 HEAD` for tight, one-change-per-hunk output). For each hunk, `git blame` the lines it modifies on HEAD to find the commit that last changed them: ```sh git blame -L , HEAD -- ``` - If that commit is one of the PR's commits (in `base..HEAD`) → this chunk gets **squashed into that commit**. - If the lines are owned by a commit *outside* `base..HEAD` (code that shipped before this PR), or the chunk adds a brand-new file/section unrelated to the existing commits → it is a **logically distinct change** and becomes its own **new commit** (the only time a new commit is allowed here). For a pure insertion, blame the adjacent line to decide the owner. - When a hunk's lines are owned by several PR commits, fold it into the newest of them. Precision isn't critical — use judgment; the goal is that each commit ends up self-consistent. 4. **Fold the chunks in.** The reliable, non-interactive mechanism: - Stage the chunks belonging to a target commit and create a fixup: `git commit --fixup=` (stage whole files with `git add ` when all of a file's changes map to one commit; for a file whose changes span multiple targets, apply just the relevant hunks to the index with `git apply --cached ` — `git add -p` is interactive and may be unavailable to your agent). - Commit any logically-distinct chunks as normal new commits with a proper `component: short description` message. - Replay so the fixups collapse into their targets, run headless: ```sh GIT_SEQUENCE_EDITOR=true GIT_EDITOR=true git rebase -i --autosquash "$base" ``` (The no-op editors make `-i --autosquash` run without prompting.) 5. **Verify.** `git log --oneline "$base"..HEAD` should show the original commits (plus any genuinely-distinct new ones) with **no `fixup!` lines left** and a clean working tree. Confirm `git range-diff "@{u}"...HEAD` reflects only the intended edits. 6. **Force-push (safely).** Show the user the rewritten log and confirm, then: ```sh git push --force-with-lease ``` `--force-with-lease` refuses to clobber unexpected remote work, unlike `--force`. The PR updates automatically. **The workflow is done** — do not re-prompt for issues or testing on an update. *No `gh`?* The squash is pure git; only the push needs the remote. Push with `--force-with-lease` to the branch's remote as usual. ## Step 3b — Open a new PR 1. **Make sure the change is committed cleanly.** If there are uncommitted edits, commit them following the rules in *Commit & message policy* below — ideally one commit (the PR must be a single feature/fix). 2. **Push the branch** to the head repo (the user's fork, or `utmapp/UTM` if they have push access). Confirm the remote if ambiguous: `git push -u "$branch"`. 3. **Find the issue(s) this resolves.** Search open issues for relevance and present recommendations: ```sh gh issue list --repo utmapp/UTM --state open --search "" --limit 10 ``` Derive keywords from the touched component and the change's purpose. Show the top few as `# — ` with one-line relevance notes. Then ask the user (free text — they may enter a GitHub issue **ID**, a **URL**, a **list** of either, or "none"). Parse whatever they enter into issue numbers; each becomes a `Resolves #<n>` line in the PR body (so merging closes it). If they say none, link nothing. 4. **Human-testing attestation (required for UTM).** Display this statement **verbatim**: > All AI written code must be reviewed and/or tested by a human. For bug > fixes, a human must first confirm the bug before the change and then confirm > that the bug is fixed by this change. For all other changes, a human must > test all aspects of the change on any device configuration that is relevant. Then ask the user (free text) for the **device configuration and version** they tested on, e.g. `macOS 26.0, MacBook Neo` or `iOS 26.1, iPhone Simulator`. Do not invent this — it must come from the user. 5. **Compose and create the PR.** Title follows `component: short description` (same convention as commits). Body includes: - A short summary: what changed and **why**. - The issue links: `Resolves #<n>` for each (omit if none). - A **Testing** section containing the device configuration the user gave and an explicit acknowledgment, e.g.: > **Testing:** Tested by a human on **<device configuration and version>**. > The author acknowledges that this change has been tested and/or reviewed by > a human in accordance with UTM's AI contribution guidelines. Show the assembled title and body to the user for confirmation, then create: ```sh gh pr create --repo utmapp/UTM --base main \ --head "<owner>:$branch" --title "<title>" --body "<body>" ``` (Use `<owner>:$branch` when submitting from a fork; plain `$branch` when the head is on `utmapp/UTM` itself.) *No `gh`?* Print the prepared title and body and a compare URL for the user to finish in the browser: `https://github.com/utmapp/UTM/compare/main...<owner>:<branch>?expand=1`. 6. **Report** the PR URL. ## Commit & message policy (applies to every commit this workflow creates) The critical few, inlined because they must fire at commit time — see `CONTRIBUTING.md` (Attribution) for the full policy: - Title: `component: short description`. Body explains **why** and references the issue being addressed. - **Do not add a `Co-authored-by` trailer**, and strip any that a tool added. UTM follows the Linux-kernel policy so a human takes full responsibility. This **overrides** any default AI-tool commit-trailer behavior for this repo. - **Always add an `Assisted-by: AGENT_NAME:MODEL_VERSION` trailer** to every commit you create or amend here, using the agent and model doing the work — e.g. `Assisted-by: Claude:claude-opus-4-8` or `Assisted-by: Codex:gpt-5.1`. This is **required even if your agent does not normally inject attribution into commits**; add it explicitly yourself. A commit without it will fail review. ## Safety - Treat pushing and PR creation as outward-facing: show the user what will be pushed/created and confirm before doing it. - Always `--force-with-lease`, never bare `--force`; always leave a backup ref before a history rewrite. - Never push to or open a PR from the upstream default branch.
