Use when NPC detection, line of sight, hearing, last-known position, alert sharing, or chase acquisition/drop behavior is unstable, omniscient, or inconsistent with stealth feedback.
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
# Enemy Perception This skill owns **evidence that an NPC can perceive**. `enemy-ai` consumes that evidence; `stealth-info` presents player-facing awareness; `collision-layers` owns collision/filter policy. ## Modes | Mode | Evidence | |---|---| | cone-sight | origin + FOV/range + line of sight query | | hear-ring | authored noise event + propagation/range rule | | last-known | timestamped last confirmed position/evidence | | alert-share | bounded ally notification with source and expiry | Modes may be combined when the project requires it; do not infer omniscience from combination. ## Acquisition and release Publish sample cadence, acquire threshold/delay, release threshold/delay, and any hysteresis. Hysteresis prevents one noisy ray or one threshold-crossing frame from flipping combat state every tick. A sight query declares sensor origin(s), target sample point(s), range/FOV policy and line of sight geometry. Use the project's collision query filtered by `collision-layers`; do not use visibility of the render mesh as gameplay truth. Multiple sample points, partial cover, smoke, portals or special sensors are project-specific policies. …

How to install
mdr add jammyfu/open-game-skills/enemy-perception@sha256:4b141aa7543d196eThe line at the top of this page pins the label git:20260913.74cd25b, 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.
