nav-mesh SKILL.md skillA
nav-mesh from jammyfu/open-game-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when AI or companion pathfinding needs an explicit traversability graph, agent profile, dynamic obstacle update, or reproducible path/no-path evidence. It owns navigation data, not physics collision or world rules.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Nav mesh Ask: `baked-static | dynamic-carve | off`. ## Ownership `nav-mesh` owns agent traversability, path requests, authored traversal links, and nav revisions. Physics/collision stays with the engine or `collision-layers`; hazards stay `hazard-volume`; door/quest truth stays with its gameplay owner. ## Contract For every navigation profile publish: - `agent_profile_id` - radius / height / step / slope limits - movement capabilities such as walk, jump-link, climb-link, swim-link - current `nav_revision` For every path request publish `request_id`, start/end, profile, nav revision, result and first failure reason. Static geometry may be baked. Runtime changes may use carving, tiled rebuilds, authored links, or another engine-supported update strategy. **Opening a door does not universally require a full rebuild.** Update only the connectivity representation the project actually uses. A gap is traversable only when the selected agent profile and authored traversal data say so. Do not globally mark all jump gaps unreachable. ## Runtime rules 1. Path queries read one coherent nav revision. 2. Dynamic obstacle updates publish a new revision before new queries use it. …

How to install
mdr add jammyfu/open-game-skills/nav-mesh@sha256:37d39a1c42451b13The line at the top of this page pins the label git:20260913.84ad517, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
