design-action-combat

design-action-combat is a skill for Claude Code, Codex from devinilabs/pro-skill. It costs 52 tokens per session (354 once invoked), scanned A, a copy of design-action-combat, MIT.

A skill for designing and testing readable combat in web games, including attacks, blocking, dodging, weapons, and boss phases.

In plain words
What is it for?
Use it to define attack windows, collision results, defensive choices, combat feedback, boss behavior, and deterministic tests.
Why use it?
It replaces animation-based guesses with explicit timing and testable outcomes, making combat easier to tune and debug.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-action-combat scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

What it actually says

Design Action Combat

Treat combat as explicit state machines with visible, testable timing rather than animation-driven guesses.

Specify every combat verb

For each player or enemy action, define: startup, active window, recovery, cancellation rules, resource cost, contact shape, damage/posture outcome, cooldown, and feedback. Make telegraph, danger, contact, and recovery readable at normal camera distance.

Use authoritative outcomes

  • Drive hits, blocks, parries, and interrupts from authoritative collision/contact events.
  • Require direction, range, phase, and state validity before resolving an outcome.
  • Apply each contact once using stable action and target identifiers.
  • Keep visuals downstream of resolved simulation events.

Tune for decisions

Give each defense a distinct purpose: spacing, dodge, timed guard, interruption, or resource trade. Avoid unpunishable attacks, recovery loops, unavoidable damage, and dominant spam. Boss phases must alter decision pressure without invalidating learned timing.

Test combat deterministically

Cover early/late timing, wrong direction, out-of-range contact, multiple targets, interrupted actions, phase changes, cooldown boundaries, pause/frame step, equip swaps, and repeated inputs. Use seeded or queryable review scenarios instead of requiring long campaign playthroughs.

Verify in play

Test at realistic frame rate and camera distance. Confirm that player intent, contact feedback, health/posture changes, sound/VFX, and target state agree. Check reduced motion and input alternatives before release.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
