Implementation Reference
- src/tools/pull-requests.ts:364-390 (handler)The core handler function that validates input using Zod schema, calls the GitHub API (Octokit) to list review comments on a pull request, maps the response, and handles errors.
export async function getPullRequestComments(args: unknown): Promise<any> { const { owner, repo, pull_number } = GetPullRequestCommentsSchema.parse(args); const github = getGitHubApi(); return tryCatchAsync(async () => { const { data } = await github.getOctokit().pulls.listReviewComments({ owner, repo, pull_number, }); return data.map((comment) => ({ id: comment.id, user: comment.user ? { login: comment.user.login, id: comment.user.id, } : null, body: comment.body, created_at: comment.created_at, updated_at: comment.updated_at, path: comment.path, position: comment.position, commit_id: comment.commit_id, url: comment.html_url, })); }, 'Failed to get pull request comments'); } - src/utils/validation.ts:174-176 (schema)Zod schema for input validation: requires owner, repo (from OwnerRepoSchema), and pull_number.
