ghost-line SKILL.md skillA
ghost-line from jammyfu/open-game-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jammyfu/open-game-skills/ghost-line@git:20260913.9a1408ePins git:20260913.9a1408e in mdr.lock. Pin the fingerprint instead.

Use when a recorded path, replay or racing ghost must be reproduced against a specific track/ruleset while remaining presentation-only and isolated from the live player's simulation truth.
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
# Ghost line Ask the source: own-best, downloaded, event-pack, debug-replay, off, or existing. ## Contract Publish: - stable `ghost_replay_id` and replay schema revision - source build/ruleset ID - `track_revision` / world revision - versioned `input_schema` or state-sample schema - RNG/seed references when required - explicit `compatibility` predicate and fallback - presentation/collision policy ## Ownership This skill owns ghost/replay compatibility and playback intent. Vehicle/gameplay simulation remains with its owning systems; `gameplay-harness` may provide deterministic tape infrastructure where appropriate. ## Rules 1. A ghost may replay semantic inputs, canonical state samples or another authored replay format; input replay is not universal. 2. Incompatible track/ruleset/schema revisions are rejected, migrated or clearly degraded according to policy; geometry mismatch alone does not dictate one universal response. 3. Ghost presentation cannot alter live-player speed, collision, targeting, rewards or timing unless the project explicitly defines a competitive interaction mode elsewhere. …

How to install
mdr add jammyfu/open-game-skills/ghost-line@sha256:703b7d36d5447bb1The line at the top of this page pins the label git:20260913.9a1408e, 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.
