name: orca-review-action description: Set up, reconfigure, troubleshoot, or remove OrcaCode Review — AI pull-request review powered by OrcaRouter — in a GitHub repository. Handles the whole lifecycle end to end without asking the user to run a CLI. Use whenever the user mentions OrcaCode Review, OrcaRouter code review, "@orcarouter code review", or /orcacode-review, and whenever they ask to set up AI code review on a repo, add the orca-code-review action, change which severities block merges, find out why a review did not run or did not post findings, or take the review workflow back out. metadata: version: "1.0.0"

OrcaCode Review

OrcaCode Review reviews every pull request with an LLM, posts findings as inline comments, and fails a status check when serious issues are found. Model selection lives in OrcaRouter, not in the repo.

It runs as a GitHub Action: a workflow file in the repo plus one secret. Write access is all it takes, and an agent can complete the whole setup.

Severity contract: P0 critical / P1 high → ❌ block. P2 advisory → 💬 comment.

What you can do with this skill

You carry out all of these yourself — writing files, running gh, and asking the user only for the decisions that are genuinely theirs. Never tell the user to go run an installer; that is what this skill replaces.

Pick the route

Jump straight to the section the table above points at. Do not run the install flow on a repo that already has the workflow — go to Reconfigure instead.

Run this first in every route — it tells you which one applies:

git rev-parse --show-toplevel && \
  gh repo view --json nameWithOwner,visibility,defaultBranchRef 2>/dev/null; \
  ls .github/workflows/ 2>/dev/null | grep -i 'orca\|code-review'

If gh is missing or unauthenticated, everything still works — you just hand the user web URLs instead of running commands. Say so once and move on.

Install

1. Preflight

Confirm all three, and stop with a specific message if any fails:

• Inside a git work tree with a GitHub origin remote.
• No existing OrcaCode workflow (if there is one → Reconfigure).
• Record the repo's nameWithOwner, visibility, and default branch — later steps need them.

2. Ask for the key decisions

Ask these with one AskUserQuestion call. Include the fourth question only when `visibility` is `PUBLIC` — it is a spend-control decision that does not exist on a private repo, and asking it there is noise.

Q1 — "Where should review settings live?" (settings input)

• OrcaRouter dashboard (recommended) → settings: "true". Models, review mode,

severity rules, and rubric change from the console with no workflow edit. Dashboard values win unless a with: input differs from its documented default.

• This workflow file → settings: "false". Skips the dashboard fetch entirely; the

YAML is authoritative and nothing server-side can override it. Pick this for repos under change control.

Q2 — "Which findings should block the merge?" (block-on input)

• P0 and P1 (recommended) → "P0,P1". The default contract.
• P0 only → "P0". Blocks only critical issues; P1 still posts inline.
• Nothing — comment only → "". The check always passes. Good for a trial period.

Q3 — "What happens when a PR's diff is too large to review?" (on-oversized-diff)

• Fail the check (recommended) → "fail". A diff padded past max-diff-kb /

max-diff-files cannot be used to slip past a required merge gate.

• Pass with a notice → "pass". The skip notice posts and the check stays green.

Q4 — public repos only — "Who gets an automatic review?" (auto-review-authors)

• Known contributors only (recommended) → "OWNER,MEMBER,COLLABORATOR,CONTRIBUTOR".
• Everyone → "".

Say plainly why Q4 exists: the workflow runs on pull_request_target with your OrcaRouter secret, so on a public repo a stranger's PR can spend from your wallet. Also tell them to set a budget + alert on the key at <https://www.orcarouter.ai/console/token>.

Everything else keeps its default. Do not ask about judge-model, concurrency, engine-version, or precision-filter during install — see references/inputs.md if the user brings them up unprompted.

3. Write the workflow

Copy assets/workflow.yml to .github/workflows/orca-code-review.yml, then set the four values from step 2 under with:. Omit any input the user left at its default — a workflow that only lists what it overrides stays readable and lets the dashboard own the rest.

Keep the if: condition and the on: block exactly as shipped. They encode two things that are easy to break: pull_request_target is what lets a fork PR be reviewed at all, and the author-association check on issue_comment is what stops any drive-by commenter from spending your quota with /orcacode-review.

Show the user the final file before committing.

4. Have the user add the API key — with gh, themselves

The secret must be named exactly ORCAROUTER_API_KEY.

This is the one step you do not perform. Stop, hand the user this command, and wait for them to confirm they have run it:

! gh secret set ORCAROUTER_API_KEY --repo <owner/name>

gh prompts for the value on their terminal, so the key goes from their keyboard straight to GitHub. It never passes through you.

Never ask them to paste the key into the chat, read it out of a file or an env var, or pass it on a command line. A pasted key is in the transcript forever; a key in argv is visible to every process on the machine via ps. There is no version of this you can do "carefully" — the only safe handling is not handling it.

They can create or copy a key at <https://www.orcarouter.ai/console/token>.

Without gh, send them to https://github.com/<owner>/<name>/settings/secrets/actions/new and have them add it in the browser.

Then confirm it exists without ever seeing its value:

gh secret list --repo <owner/name> | grep ORCAROUTER_API_KEY

If it is not there yet, do not continue to the test PR — the run will fail on auth and the failure will look like a configuration bug rather than a missing key. Wait, or skip to step 8 and list it as outstanding.

5. Switch it on in the OrcaRouter console

Point the user at OrcaRouter → Apps → OrcaCode Review (<https://www.orcarouter.ai/>) to turn it on and choose review models. Reviews will not run until it is enabled.

There is no API for this step today, so it is the user's to do.

6. Commit and open a test PR

Commit on a branch, push, and open a PR — do not commit straight to the default branch. The PR is also the test: the workflow must run against a real pull request to prove out.

gh pr create --fill && gh run watch

7. Make the gate real

A passing check blocks nothing until it is required. Walk the user through Settings → Branches / Rulesets → Require status checks to pass and adding the `review` check, or offer to do it:

gh api -X PATCH repos/<owner>/<name>/branches/<default>/protection/required_status_checks \
  -f 'checks[][context]=review'

Confirm before running — branch protection changes affect everyone on the repo.

8. Report, and close on what they still owe

Tell the user, concretely: the workflow path, the settings you chose, whether the secret and required check are in place, and the result of the test run. If any step was skipped (no gh, protection not applied), say which.

End the message with their outstanding actions as copy-pasteable commands — not prose describing them. Anything you could not do yourself belongs here, and the API key is almost always on the list because you are not allowed to do it:

! gh secret set ORCAROUTER_API_KEY --repo <owner/name>

Re-check with gh secret list before claiming it is done. Do not report the install as complete while the secret is missing: the workflow is in place but every run will fail on auth, and "installed" would be a lie the user only finds out about on their next PR.

Reconfigure

Read the existing .github/workflows/orca-code-review.yml first, then check whether settings: "false" is set.

If the dashboard owns settings (`settings` absent or `"true"`) — most knobs are not in the file. Review mode, models, exhaustive mode, quiet mode, rubric, and the fix-first/block-on tuning all live at OrcaRouter → Apps → OrcaCode Review. Send the user there rather than editing YAML, and explain the precedence rule: an input written in the file only wins if it differs from its documented default.

If the file is authoritative (`settings: "false"`) — edit it. Ask with AskUserQuestion which knobs to change, offering only what is relevant:

• Merge policy (block-on), exhaustive early-stop (fix-first), and which severities post

inline (Report severities, dashboard-only).

• Diff limits (max-diff-kb, max-diff-files) and on-oversized-diff.
• Precision filter (precision-filter, judge-model, judge-threshold).
• Run reporting (report) and token metering (meter).

references/inputs.md has every input, its default, and what it actually controls. Read it before answering a question about behavior — do not guess a default.

State the before → after for each value you change, and note that the new settings take effect on the next push to any open PR.

Troubleshoot

Gather evidence before theorizing:

gh run list --workflow orca-code-review.yml --limit 5
gh run view <run-id> --log-failed

references/troubleshooting.md maps each symptom to its cause and fix. The four that account for most reports:

• No run at all — the PR is a draft and trigger is ready_for_review, the author

is outside auto-review-authors, or the app is off in the dashboard.

• Run fails immediately, auth error — ORCAROUTER_API_KEY is missing, misnamed, or

scoped to an environment the job cannot read.

• "Diff too large" notice and a red check — expected behavior with

on-oversized-diff: "fail". Split the PR, or raise max-diff-kb / max-diff-files.

• Reviews work but the console's Settings/Analytics tabs are empty — @v1 points at

a commit older than scripts/settings.mjs / scripts/report.mjs. There is no error for this; verify with git ls-tree v1 scripts/ against the action repo.

Report the actual failing output, not a paraphrase of it.

Uninstall

Confirm with the user first, then in this order:

1. Drop the required check — remove review from branch protection before deleting

the workflow. A required check whose workflow no longer exists never reports, and every PR blocks forever with no way to clear it.

1. Delete the workflow — rm .github/workflows/orca-code-review.yml, commit, push.
2. Leave the secret — say that ORCAROUTER_API_KEY is harmless to keep and is worth

keeping if they may reinstall. Delete it only if they ask.

1. Mention the dashboard — turning the app off at **OrcaRouter → Apps → OrcaCode

Review** stops any remaining billing.

Do not delete old review comments. They are part of the PR history.
