grapple-swing SKILL.md skillA
grapple-swing 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/grapple-swing@git:20260913.dedc8dbPins git:20260913.dedc8db in mdr.lock. Pin the fingerprint instead.

Use when an actor attaches to a point or body for pulling, swinging or traversal and the project needs stable latch identity, motion ownership, release semantics and collision-safe recovery.
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
# Grapple and swing Ask the mode: latch-pull, pendulum, tow-object, tether, no-grapple, or existing. ## Contract Publish: - stable `grapple_session_id` and revision - stable `latch_id` / target identity - latch eligibility predicate and query owner - explicit `motion owner` during attached states - rope/constraint parameters owned by physics/project data - `release request` identity and release velocity policy - collision/fall/recovery behavior ## Ownership This skill owns grapple state transitions and attachment intent. Aim/target query, physics constraints, character locomotion, camera collision and fall rules stay with their owners. ## Rules 1. Latch selection is deterministic for a declared candidate revision and cannot depend on render order. 2. While attached, exactly one system owns actor transform/velocity authority; character movement and rigid-body constraints do not fight each other. 3. Duplicate latch/release callbacks are idempotent by session/request identity. 4. Tagged-only, free-surface, assisted or authored targets are project modes, not universal defaults. …

How to install
mdr add jammyfu/open-game-skills/grapple-swing@sha256:c0ee43266cb6cc0eThe line at the top of this page pins the label git:20260913.dedc8db, 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.
