HiveMind exposes 8 tools via STDIO with Spanish descriptions and reasonable naming (verb_noun pattern). However, critical gaps undermine production readiness: (1) Parameter descriptions are sparse or missing entirely, most params lack type info beyond the schema. (2) Output schemas are not documented; LLMs cannot predict response structure. (3) Error handling is absent, no guidance on retryability, recovery, or actionable next steps. (4) Security concerns: write_local_file and run_local_tests accept arbitrary paths/commands with only basic allow-list validation; no mention of sanitization or injection prevention. (5) Tool descriptions are moderately detailed but lack WHEN/WHY guidance for LLM selection. Average tool score: 52/100.

• Document output schemas for all tools. E.g., hivemind_read_local_file returns {content: string, path: string, size_bytes: number}. hivemind_list_my_cards returns {cards: [{id, name, list, status}], total: number}.
• Add parameter descriptions with format/constraint guidance. E.g., 'path: Relative or absolute path within allowed_paths (see system prompt). Must not contain .. or symlinks.' 'command: Shell command to execute (bash/sh only). Timeout 60s. No sudo, no rm -rf, no network access.'
• Implement error handling with recovery guidance. E.g., 'If semaphore denies write, return {error: "conflict", conflicting_agent: "agent-2", suggestion: "Try again in 30s or contact agent-2 to coordinate."}' instead of a bare error.
• Add a discovery tool (e.g., hivemind_list_trello_lists) to help agents find valid list_id values without hardcoding. Or accept list names (e.g., 'In Progress') and resolve internally.
• Validate and sanitize command input in run_local_tests. Reject commands containing rm, dd, >, |, &&, ||, or other shell metacharacters unless explicitly whitelisted. Return clear error: 'Command contains forbidden pattern: rm. Allowed: npm test, pytest, cargo test.'
