9 tools with basic descriptions but critical gaps in schema completeness and parameter documentation. All tools have descriptions (10-50 chars), but most lack detailed parameter descriptions and output schema documentation. No tool annotations (readOnlyHint/destructiveHint). Naming is verb-based but generic (read_*, list_*, run_*). No pagination support despite list_sessions and list_artifacts. Error handling present but not recovery-guided. Schemas visible for 4/9 tools; 5 tools have empty input objects with no parameter documentation.

• Add tool annotations to schema: mark read_* and list_* tools with readOnlyHint=true; mark create_session with destructiveHint=true (or idempotentHint if retryable).
• Document output schemas for all tools. E.g., list_sessions should declare it returns {sessions: [{sessionId, title, status}], activeSessionId?: string}.
• Add pagination to list_sessions and list_artifacts: include limit (default 20, max 100), offset, and total_count in response. Update descriptions to state 'Returns up to 20 sessions; use offset for pagination.'
• Expand parameter descriptions with constraints. E.g., 'limit: Maximum number of sessions to return (1 - 100, default 20)'. For metadata, specify required fields: 'metadata: Object with required keys source (string), chatId (number), correlationId (string)'.
• Add error recovery guidance. E.g., read_file should document 'Returns error if path does not exist or is outside allowed directory. Verify path with search_codebase first.'
