Pr Review CI Fix

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: COMPOSIO_API_KEY.

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:

• GITHUB_GET_A_PULL_REQUEST
• GITHUB_LIST_PULL_REQUESTS_FILES
• GITHUB_CREATE_A_REVIEW_FOR_A_PULL_REQUEST
• GITHUB_LIST_WORKFLOW_RUNS_FOR_A_REPOSITORY
• GITHUB_DOWNLOAD_WORKFLOW_RUN_LOGS
• GITLAB_GET_SINGLE_MERGE_REQUEST
• GITLAB_LIST_MERGE_REQUEST_DISCUSSIONS
• GITLAB_CREATE_NEW_MERGE_REQUEST_NOTE

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

Review Workflow

1. Pull the PR metadata + diff:

   composio execute GITHUB_GET_A_PULL_REQUEST \
     -d '{"owner":"acme","repo":"app","pull_number":482}'
   composio execute GITHUB_LIST_PULL_REQUESTS_FILES \
     -d '{"owner":"acme","repo":"app","pull_number":482}'
   

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

   composio execute GITHUB_CREATE_A_REVIEW_FOR_A_PULL_REQUEST -d '{
     "owner":"acme","repo":"app","pull_number":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:

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

2. Pull logs:

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

3. Parse failure → patch locally (the agent writes the fix into the working tree).
4. Commit + push via local git, then re-poll step 1 until conclusion=success.
5. 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
