38 tools with minimal schema documentation and sparse parameter descriptions. Most tools show only owner/repo parameters with basic type info; no output schemas documented. Descriptions are present but generic (avg ~60 chars, well below 194-char baseline). No error handling guidance, no parameter constraints (enums, ranges), no idempotency hints. Tool names follow verb_noun convention (good), but parameter descriptions lack actionable detail (e.g., 'The owner of the repository' repeated 38 times). No evidence of pagination support, result limits, or chaining IDs in responses. Security-sensitive tools (delete_file, create_repository) lack confirmation/dry-run patterns. Schemas visible in filter.py but incomplete, most tools show only 2 params with no output schema.

• Document output schemas for all 38 tools. Specify which fields are returned, their types, and which are required. Example: get_file_contents should return {content: string, encoding: string, size: number, last_modified: ISO8601}.
• Expand tool descriptions to 100-200 chars. Explain WHAT the tool does, WHEN to use it vs similar tools, and any prerequisites. Example: 'Retrieve the raw contents of a file from a GitHub repository. Use this to read source code, config files, or documentation. Requires read:contents permission.'
• Add parameter constraints: enums for status/state fields (e.g., pull_request state: [open, closed, merged]), ranges for numeric params (e.g., page_size: 1-100), and format hints for IDs (e.g., 'GitHub username or user ID').
• Implement pagination for list_* tools: add limit (default 20, max 100) and offset/cursor params. Return total_count and next_cursor in response. Document result limits in descriptions.
• Add confirmation/dry-run patterns for destructive tools (delete_file, create_repository). Require explicit confirmation parameter or offer a dry_run mode that returns what would happen without executing.
