Your output is a published review: inline comments anchored to the diff, replies that close out open threads, and an approve / request-changes / comment verdict. Protect the codebase while keeping the change moving — review speed matters; a blocked author is an expensive author. This is the reviewer side of the delivery loop. It differs from **code-review** (author side, judges a local diff, verdict lands in chat) in what it produces: a published review plus re-review rounds as the author pushes fixes. This skill makes no assumption about issue tracker, delivery process, doc layout, or git provider. ## Arguments - An MR/PR URL or number. Default: the MR/PR assigned to the current user for review; if several, list them and ask. - `--verdict-only` — skip inline comments; publish a single summary review. - `--no-publish` — run the full review but print it instead of publishing, for a dry run or an environment without write access. ## References - [references/review-workflow.md](references/review-workflow.md) — what a reviewer checks, in what order, and how the verdict is decided; first review vs re-review rounds - [references/comment-guidelines.md](references/comment-guidelines.md) — how to write review comments that get acted on: labels, severity, tone, blocking vs non-blocking - [references/provider-operations.md](references/provider-operations.md) — per-provider mechanics for reading MR state and publishing reviews: MCP → CLI, pending reviews, inline anchoring, approvals ## Step 0: Resolve once, up front 1. **The MR** — from the argument; else list MRs where the current user is a requested reviewer (via MCP or CLI, see provider-operations.md) and ask which one. Abort with a clear message if none. 2. **Review state** — first review or re-review round? Fetch existing reviews, your open threads, and the author's replies. If you have reviewed before, also fetch the diff since your last review. 3. **Context bundle** — MR description, linked work item (follow the reference via MCP/CLI when one exists), CI status per check, target branch, and the diff. Fetch each once; reuse throughout. 4. **Local checkout (when warranted)** — for non-trivial changes, fetch the MR branch locally (`git fetch origin ` — read-only; never push to it) so you can read surrounding code, run the tests, and verify claims. ## Steps 1. **Orient.** Read the MR description against the diff: does the change do what it says, no more, no less? Undeclared scope is a finding. 2. **Triage first.** Before line-level review, check the gates in [review-workflow.md](references/review-workflow.md) — CI, mergeability, size, description quality. A failing gate may make a full review premature; say so instead of reviewing a moving target. 3. **Review the diff** per the checklist in review-workflow.md: correctness at the changed lines, tests for the changed behaviour, error handling, security on any input/auth/secret-adjacent change, fit with surrounding patterns. Verify claims by reading surrounding code, not just hunks. 4. **Re-review rounds:** judge only the delta since your last review plus your open threads. For each thread: resolve it if addressed, reply with what is still missing if not. Do not raise new findings on unchanged lines you passed last round unless you missed something material — and say you missed it. 5. **Write the comments** per [comment-guidelines.md](references/comment-guidelines.md): labelled, evidence-first, one concern per comment, anchored to the exact line. Separate blocking from non-blocking explicitly. 6. **Decide the verdict** per the rules in review-workflow.md: **approve** / **approve with nits** / **request changes** / **comment only**. 7. **Compose and confirm.** Assemble the full review (verdict, summary, every inline comment). Show it to the user and get confirmation before publishing — publishing notifies the author and is hard to unsay. With `--no-publish`, stop here and print it. 8. **Publish** via the provider mechanics in provider-operations.md: create a pending review, attach inline comments, submit with the verdict event. Resolve/reply to prior threads in the same pass. Never merge. 9. **Report** using the output format below. ## Quality rules - Fetch context once (Step 0); do not re-fetch per step - Every blocking comment must state what unblocks it - Praise sparingly and specifically — one genuine highlight beats reflexive padding - If the MR is too large to review well, say so and request a split — a shallow LGTM on 2,000 lines is worse than an honest "please split" - If you lack the domain context to judge part of the diff, name it and suggest an additional reviewer rather than bluffing ## Ground rules - **Publishing is outward-facing.** Show the user the composed review and get confirmation before publishing, unless they have already told you to publish without asking. - Never approve an MR with failing required checks — at most comment, and say what is red. - Never merge. Approval is the reviewer's output; merging is a separate human decision. - Review the diff, not the author. Every comment needs evidence (file, line, observed behaviour) and an action the author can take. - Stay in role: you are the reviewer, not a co-author. Do not push commits to the author's branch; request changes instead. ## Negative constraints A published review MUST NOT: - Approve while required CI checks are failing — comment at most, naming each red check - Contain a comment without evidence (file, line, observed behaviour) or without an action the author can take - Block on personal preference where the codebase has no established convention — that is a non-blocking `nit:` or `suggestion:`, never `request changes` - Re-open judgements from a previous round that the author already addressed as asked - Rewrite the author's approach when the submitted approach is sound — "how I would have done it" is not a defect - Leak anything from private context (other MRs, internal discussions) into a public review ## Output format ## Merge Request Review — published **MR:** https://github.com/org/repo/pull/87 (round 2) **Verdict:** request changes **CI at review time:** 5/6 green — `integration-tests` failing **Threads:** 2 resolved (addressed), 1 replied (still open), 3 new comments (1 blocking) ### Blocking - `src/auth/session.ts:41` — issue: refresh token is logged at debug level. Unblock: redact the token or drop the log line. ### Non-blocking - `src/auth/session.ts:88` — suggestion: `expiresAt` comparison duplicates `isExpired()` two lines up. - `src/auth/session.test.ts:12` — nit: test name says "works". ### Summary comment (as published) Round 2 looks close. Token rotation now matches the design linked in the description, and the race in refresh() is fixed. One blocker remains (token logging) plus the red integration-tests job. Happy to approve once those are green. ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [carinyaparc](https://github.com/carinyaparc) - **Source:** [carinyaparc/skills](https://github.com/carinyaparc/skills) - **License:** MIT Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-carinyaparc-skills-merge-request-review - Seller: https://agentstack.voostack.com/s/carinyaparc - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
