Team Nexus exposes 23 tools via Makefile targets with minimal schema documentation. Most tools lack visible input schemas in the source code, only 6 tools (analyze_portfolio, kanban_create, discord_post_status, mcp_add_command, mcp_add_url, mcp_register_template) have explicit parameter definitions. The remaining 17 tools have empty or inferred schemas. Descriptions are present but generic (avg ~80 chars, well below the 194-char baseline for A+ tools). No output schemas documented. No error handling guidance. Tool names follow verb_noun convention (kanban_list, profile_validate) but lack clarity on mutual exclusivity and dependencies. Security concerns: no mention of secret injection, permission gates, or audit trails. Composition is poor, many tools are Makefile wrappers around shell commands, not true MCP tool implementations with structured I/O.

• Add explicit input schemas to all 17 tools lacking them. For zero-parameter tools (kanban_init, workspace_init), use an empty object schema {}. For tools with optional parameters (hermes_doctor, mcp_list), document the PROFILE parameter with type, description, and default value.
• Document output schemas for all tools. Example: kanban_list should return {tasks: [{id, title, assignee, status, created_at}], total_count}. profile_render should return {rendered_files: [path], output_dir, mode}. This enables LLMs to chain tools and extract the right fields.
• Expand descriptions to 100 - 200 characters. Include WHAT the tool does, WHEN to use it, and what it returns. Example: 'Initialize the shared Kanban board and install mission-contract DB triggers. Call this once before creating tasks. Returns success status and trigger count.' instead of 'Initialize the shared Team Nexus Kanban board and mission contract triggers'.
• Add error handling and recovery guidance to all WRITE and DESTRUCTIVE tools. Example for kanban_mission_contract_uninstall: 'Removes DB mission-contract triggers. WARNING: This is irreversible. If you need to restore triggers, call kanban_mission_contract_install. Returns success status or error with recovery steps.'
• Implement permission checks and audit logging. Gate kanban_create, profile_render, and mcp_add_* behind role-based access control. Log all state-modifying calls with caller ID, timestamp, parameters, and result. Add a dry_run parameter to profile_render and kanban_create to support confirmation workflows.
