Unity NavMesh Skills

Bake or clear NavMesh data, calculate paths, sample positions, set area costs and configure NavMeshAgent and NavMeshObstacle components. Parameters come from the schema (GET /skills/schema?category=NavMesh&wire=v2); execution and dryRun rules: root SKILL.md.

When to use

• Setting up navigation for a scene
• Baking or clearing a NavMesh
• Testing agent paths or nearest reachable points
• Tuning agent or obstacle settings and area traversal costs

Rules

• navmesh_bake runs synchronously and blocks the Editor; on large scenes warn the user first.
• Re-bake after scene geometry changes; the NavMesh does not follow them.
• navmesh_clear is a Delete operation: it is refused in Approval and Auto, and runs only in Bypass or when allowlisted.
• Query skills (navmesh_calculate_path, navmesh_sample_position, navmesh_get_settings) are read-only and run in every mode; the write skills need a grant under Approval.

Pitfalls

• navmesh_calculate_path returns status: "NoPath" when NavMesh.CalculatePath returns false; PathPartial is not valid.
• navmesh_set_area_cost takes areaIndex 0-31 and cost >= 0.
