knockback-launch SKILL.md skillA
knockback-launch 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/knockback-launch@git:20260913.43ccc40Pins git:20260913.43ccc40 in mdr.lock. Pin the fingerprint instead.

Use when hits need authored pushback, launch arcs, gravity, airborne stun, or juggle trajectories after the applicable hitstop policy resolves.
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
# Knockback launch This skill owns intended launch parameters, not body collision response. Choose: | Mode | Output | |---|---| | ground-push | planar initial velocity/impulse plus decay or stop rule | | launch-arc | initial velocity/impulse, gravity and airborne state | | custom-trajectory | explicitly authored curve/solver when the project requires it | Publish whether launch begins immediately or after participant hitstop reaches the required state. Store vector/impulse, gravity, air-stun and any air-control rule in gameplay data, not animation clip length. `knockback-body` owns wall/floor sweeps and stop/slide/splat response. `hitstun-recover` owns action lock/recovery. `combo-design` owns juggle-route budgets. Player and enemy may share a formula, but symmetry is a project choice rather than a universal rule. ## Accept For each representative launch, log initial state, launch tick, velocity/impulse, gravity and expected contact window; replay it at different render rates. The measured arc is stable, and changing animation duration does not change physics. Collision penetration is validated separately by `knockback-body`.

How to install
mdr add jammyfu/open-game-skills/knockback-launch@sha256:82bf4b0ef8b44b0aThe line at the top of this page pins the label git:20260913.43ccc40, 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.
