23 tools with consistent naming (verb_noun pattern) and basic schemas. However, descriptions are generic (avg ~40 chars, well below 194-char baseline), parameter descriptions are sparse or missing, and output schemas are undocumented. No error handling guidance, no idempotency hints for write operations, and no permission/scope declarations. Tool definitions appear inferred from file paths rather than explicit registration code visible in the provided source. Critical gaps in LLM-facing documentation.

• Expand tool descriptions to 50 - 200 chars. Example: 'List repositories globally or within a project. Use to discover available repos before creating pull requests. Returns repo_key, repo_slug, and clone URLs.' This tells LLMs WHAT, WHEN, and WHAT TO EXPECT.
• Document output schemas for every tool. Example for list_repositories: 'Returns {repositories: [{repo_key, repo_slug, name, clone_url}], total_count, next_cursor}'. This enables tool chaining and field extraction.
• Add enum constraints to state/filter parameters. Example: list_pull_requests state param should declare enum: ['OPEN', 'MERGED', 'DECLINED']. Replace free-form strings with formal constraints.
• Add tool annotations: mark merge_pull_request and decline_pull_request with destructiveHint=true; mark all read-only tools with readOnlyHint=true. This guides LLM safety reasoning.
• Add error recovery guidance. Example for merge_pull_request: 'If merge fails with conflict, call get_diff to inspect changes, then resolve manually or decline and recreate.' This prevents agent dead-ends.
