OpenHandoff provides 4 tools with clear naming (verb_noun pattern) and reasonable descriptions (avg 85 chars). All tools have input schemas with type definitions and parameter descriptions. However, output schemas are completely undocumented, LLMs cannot predict what fields to expect from responses. Parameter descriptions lack actionable constraints (ranges, formats, enums). Error handling is absent, no guidance on recovery paths or error categorization. The server lacks security hardening (no permission gates, no audit logging). Tool composition is sound but descriptions could be more LLM-optimized per the 50-200 char baseline.

• Document output schemas for all 4 tools. Example for load_handoff: 'Returns {schema: string, title: string, decisions: [string], todos: [string], notes: string}'.
• Add parameter constraints to descriptions. For maxChars: 'Integer, 128 - 100000. Larger values may timeout.' For path: 'Directory path, must exist or be creatable.'
• Wrap tool implementations with try-catch blocks that return structured error objects: {error: string, code: string, recovery: string}. E.g., 'File not found at .context/context.json. Try calling save_checkpoint first to initialize.'
• Enhance tool descriptions to 50 - 150 chars with WHEN-to-use guidance. E.g., 'Load the current project handoff (decisions, TODOs, notes) to understand prior context. Call this first before pack_context or search_handoff.'
• Add permission checks and audit logging to save_checkpoint. Log caller, timestamp, and changes. Require explicit confirmation for overwrites via a dry_run parameter.
