Tools
Functions exposed to the LLM to take actions
| Name | Description |

| find_contradictionsA | Traverse the typed reasoning graph for active 'contradicts' edges — the sharpest of six relation types. scope='all' or 'recent_30d'. Returns {from_slug, to_slug, confidence, surfaced_at, source_run_id}. Read-only. |

Scored across 3 tools
Each tool targets a distinct operation: semantic search, contradiction graph traversal, and article retrieval by slug. No functional overlap.
All tool names follow a consistent verb_noun pattern: search_concepts, find_contradictions, get_article. Clear and predictable.
Three tools is appropriate for a focused read-only knowledge vault. Each tool addresses a core need without redundancy.
Covers search, contradiction detection, and article retrieval. Lacks a listing or browsing capability, but semantic search mitigates this gap.
