## Tool descriptions

- `remove_concept` — Soft-delete a concept from the knowledge graph. The concept and its removal reason are preserved in history.
- `get_concept` — Look up a concept by its exact ID. Returns the concept with its full context including children, edges, incoming edges, and parent. Unlike
- `list_conflicts` — List all unresolved merge conflicts in the knowledge graph, grouped by merge_group. Each group contains competing versions with full data. Call this when the user runs /merge to begin AI-assisted conflict resolution.
- `list_roots` — List all top-level concepts in the knowledge graph with their direct children. Call this at the start of a session to get a high-level project overview.
- `understand` — Query the project knowledge graph. Call this before starting any task to load relevant context about concepts, features, and architecture. Returns matched concepts with their children, edges, and parent context.
- `create_concept` — Add a new concept to the knowledge graph. Call this after completing a task to record new features, components, patterns, or decisions you built. Include specific details: parameter names, defaults, file locations, and rationale.
- `link` — Create a relationship between two existing concepts.
- `resolve_conflict` — Resolve a merge conflict by providing the correct resolved content. Read both conflict versions, verify against the current codebase, then provide the accurate resolved summary. Do NOT just pick a side — write the truth.
- `update_concept` — Update an existing concept in the knowledge graph. Call this after completing a task that changed existing features or components. Only include fields that changed.
