- ToolRegistry: named tools with parameter validation and audit logging
- 6 built-in staffing tools:
search_candidates (skills, city, state, experience, availability)
get_candidate (by ID)
revenue_by_client (top N by billed revenue)
recruiter_performance (placements, revenue per recruiter)
cold_leads (called N+ times, never placed)
open_jobs (by vertical, city)
- Each tool: name, description, params, permission level (read/write/admin)
- SQL template with validated parameter substitution
- Full audit trail: every invocation logged with agent, params, result
- Endpoints: GET /tools (list), GET /tools/{name} (schema),
POST /tools/{name}/call (execute), GET /tools/audit (log)
- Per ADR-015: governed interface before raw SQL for agents
