Server has 12 tools with explicit Zod schemas and descriptions. Naming follows verb_noun convention (get_repo, list_issues, create_issue, search_code, etc.). All tools have non-empty descriptions (avg ~100 chars). Parameters are typed with Zod and include descriptions. However, several critical gaps: (1) Output schemas are NOT documented, tools return JSON.stringify() with no schema specification for downstream tool chaining; (2) Parameter descriptions lack format/constraint details (e.g., per_page says 'default: 30, max: 100' but no min bound stated); (3) No error handling guidance, execute() blocks have no try-catch or recovery hints; (4) Jira create_issue (tool 8) has file path mismatch (listed as connectors/github/index.ts but should be connectors/jira/index.ts); (5) No pagination cursors or total counts in list tools; (6) Sensitive parameters (GITHUB_TOKEN, Jira credentials) appear to be env-injected correctly, but no explicit secret-injection pattern documented.

• Document output schemas for all tools. Define response structure (e.g., get_repo returns {stars: number, forks: number, language: string, description: string}). Enable LLM to plan chaining and extract IDs.
• Add try-catch blocks and actionable error messages. E.g., 'User not found. Try search_users() with a partial name.' or 'Invalid JQL: syntax error at position X. Valid operators: AND, OR, NOT.'
• Implement pagination with cursors and total counts. list_issues should return {issues: [...], total_count: N, next_cursor: 'abc123'} and accept cursor parameter.
• Add format constraints to parameter descriptions. E.g., issue_key: 'Jira issue key in format PROJECT-NUMBER (e.g., SDT-1234)'; per_page: 'Results per page (1-100, default 30)'.
• Fix file path mismatch for Jira create_issue tool registration and verify all tool definitions are in correct connector files.
