Implementation Reference

• src/tools/pull-requests.ts:297-337 (handler)

  The primary handler function for the 'get-pull-request-status' tool. It validates input using GetPullRequestStatusSchema, fetches the PR head SHA, and retrieves combined status checks from GitHub API.
  export async function getPullRequestStatus(args: unknown): Promise<any> { const { owner, repo, pull_number } = GetPullRequestStatusSchema.parse(args); const github = getGitHubApi(); return tryCatchAsync(async () => { // First get the pull request to get the head SHA const { data: pr } = await github.getOctokit().pulls.get({ owner, repo, pull_number, }); // Then get the combined status for the head SHA const { data } = await github.getOctokit().repos.getCombinedStatusForRef({ owner, repo, ref: pr.head.sha, }); return { state: data.state, statuses: data.statuses.map((status) => ({ context: status.context, state: status.state, description: status.description, target_url: status.target_url, created_at: status.created_at, updated_at: status.updated_at, })), sha: data.sha, total_count: data.total_count, repository: { name: data.repository.name, full_name: data.repository.full_name, owner: { login: data.repository.owner.login, }, }, }; }, 'Failed to get pull request status'); }
• src/utils/validation.ts:165-167 (schema)
