PR Review + CI Auto-Fix

Drive GitHub/GitLab PR reviews and CI triage from the shell using the Composio CLI. No tab-switching between browser, terminal, and chat.

When to Use

• A PR needs a structured review (correctness, style, risks) with inline comments.
• CI is red and you want the agent to read the logs, patch the code, and recheck.
• You want a single command that cycles: fetch diff → critique → fix → push → rerun.

Prereqs

curl -fsSL https://composio.dev/install | bash
composio login
composio link github        # or: composio link gitlab

Optional env for non-interactive runs: COMPOSIOAPIKEY.

Core Toolkits

Discover slugs with search, then pin them for reuse:

composio search "list pull request files" --toolkits github
composio search "download workflow logs" --toolkits github
composio search "create pr comment" --toolkits gitlab

Common slugs you'll reuse:

• GITHUBGETAPULLREQUEST
• GITHUBLISTPULLREQUESTSFILES
• GITHUBCREATEAREVIEWFORAPULL_REQUEST
• GITHUBLISTWORKFLOWRUNSFORAREPOSITORY
• GITHUBDOWNLOADWORKFLOWRUNLOGS
• GITLABGETSINGLEMERGEREQUEST
• GITLABLISTMERGEREQUESTDISCUSSIONS
• GITLABCREATENEWMERGEREQUEST_NOTE

Always confirm via composio execute <SLUG> --get-schema before first use.

Review Workflow

1. Pull the PR metadata + diff:

``bash composio execute GITHUBGETAPULLREQUEST \ -d '{"owner":"acme","repo":"app","pullnumber":482}' composio execute GITHUBLISTPULLREQUESTSFILES \ -d '{"owner":"acme","repo":"app","pullnumber":482}' ``

1. Summarize risk areas (auth, migrations, public APIs, tests) into a review body.
2. Post the review with inline comments:

``bash composio execute GITHUBCREATEAREVIEWFORAPULLREQUEST -d '{ "owner":"acme","repo":"app","pullnumber":482, "event":"COMMENT", "body":"Overall LGTM with 2 blocking notes.", "comments":[ {"path":"src/auth.ts","line":42,"body":"Missing null check on session"}, {"path":"src/auth.ts","line":88,"body":"Token TTL is hardcoded; move to config"} ] }' ``

CI Auto-Fix Loop

1. Find the red run:

``bash composio execute GITHUBLISTWORKFLOWRUNSFORAREPOSITORY \ -d '{"owner":"acme","repo":"app","branch":"feat/billing","status":"failure"}' ``

1. Pull logs:

``bash composio execute GITHUBDOWNLOADWORKFLOWRUNLOGS \ -d '{"owner":"acme","repo":"app","run_id":123456}' ``

1. Parse failure → patch locally (the agent writes the fix into the working tree).
2. Commit + push via local git, then re-poll step 1 until conclusion=success.
3. Post a PR comment describing each fix commit so the human reviewer sees what changed.

One-Shot Workflow File

Save as scripts/review-and-fix.ts and run with composio run --file ./scripts/review-and-fix.ts -- --pr 482:

const pr = process.argv.includes("--pr")
  ? Number(process.argv[process.argv.indexOf("--pr") + 1])
  : null;

const meta = await execute("GITHUB_GET_A_PULL_REQUEST", {
  owner: "acme", repo: "app", pull_number: pr
});
const files = await execute("GITHUB_LIST_PULL_REQUESTS_FILES", {
  owner: "acme", repo: "app", pull_number: pr
});

console.log(JSON.stringify({ meta, files }, null, 2));

GitLab Variant

Swap slugs and param names:

composio execute GITLAB_GET_SINGLE_MERGE_REQUEST \
  -d '{"id":"acme/app","merge_request_iid":482}'
composio execute GITLAB_CREATE_NEW_MERGE_REQUEST_NOTE \
  -d '{"id":"acme/app","merge_request_iid":482,"body":"CI fix pushed as commit deadbeef"}'

Troubleshooting

• Connection required for github → composio link github
• Unknown input shape → composio execute <SLUG> --get-schema
• Log download huge → stream via composio proxy against the raw API and grep locally
• Rate limits → serialize calls or lower poll frequency; avoid --parallel for the same repo
