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

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}'

Summarize risk areas (auth, migrations, public APIs, tests) into a review body.

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

Find the red run:

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

Pull logs:

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

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