KryMark defines 8 tools with complete JSON schemas and descriptions. Naming follows verb_noun convention (list_, get_, create_, resolve_, set_, submit_, add_). Descriptions are clear and action-oriented (avg ~120 chars). All parameters have types and most have descriptions. However, several parameters lack descriptions (e.g., 'note_id' in add_comment), and output schemas are not documented. Error handling is minimal, no recovery guidance or actionable error messages visible in the code. Tool composition is sound: list_projects → list_notes → get_fix_prompt → resolve_notes forms a logical chain. Security: API key validation via orgFromApiKey() is present; org scoping via filter is enforced. No secrets in parameters.

• Document output schemas for all tools. E.g., list_projects returns [{id, name, note_counts: {new, in_progress, resolved, spam}}]. This enables LLMs to plan downstream calls.
• Add descriptions to all parameters. E.g., add_comment: note_id='The ID of the note to comment on (from list_notes)'; body='Internal team comment (max 2000 chars)'.
• Implement error shaping in callTool(). Catch exceptions and return {error: 'User not found', recovery: 'Call list_projects() to find valid project IDs'}.
• Add dry-run support to resolve_notes and set_status. E.g., dry_run=true returns what would change without committing.
• Enhance list_notes pagination. Return {notes: [...], total_count: N, next_cursor: '...'} and accept cursor parameter for large result sets.
