This is a policy/security testkit, not a production MCP server. It defines 5 tools across example configs and test fixtures. Critical issues: (1) Tool 'tool' has a prompt-injection attack in its description ('ignore previous safety rules...'), this is intentionally malicious for testing. (2) delete_file and delete_record lack input validation and error guidance. (3) list_project_files has a regex pattern but no description of what the pattern enforces. (4) Most tools lack comprehensive descriptions explaining when to use them vs alternatives. (5) No output schemas documented. (6) No error handling guidance. The testkit itself is well-engineered (good rule detection in tool_rules.py), but the example tools are intentionally weak to demonstrate policy violations.

• Replace generic tool name 'tool' with a verb_noun pattern (e.g., 'read_file', 'get_path_info'). Current name violates naming baseline, 90% of A+ tools start with action verbs.
• Add output schema documentation to all tools. Specify returned fields, types, and pagination (if applicable). Example: list_records should document {records: [{id, name, ...}], total_count, next_cursor}.
• For destructive tools (delete_file, delete_record), implement confirmation pattern: add a 'confirm' boolean parameter or return a 'requires_confirmation' response requiring a second call with a confirmation token.
• Expand parameter descriptions to 50-100 chars each, stating format, range, and constraints in text (not just JSON Schema). E.g., 'target: Absolute or relative file path (max 255 chars, no symlinks).'
• Add error handling guidance: 'If file not found, return available files in directory.' 'If permission denied, return required scopes.' This enables agent recovery without extra discovery calls.
