Create Game VFX
Make the gameplay meaning visible before adding spectacle.
Specify
For every effect define trigger, owner, duration, gameplay meaning, camera-distance silhouette, color hierarchy, spawn cap, cleanup rule, and reduced-motion equivalent. Separate telegraph, contact, success, failure, and lingering status visuals.
Implement safely
Pool short-lived objects, reuse materials/geometry, cap particles, and avoid per-frame allocation. Use additive/transparency sparingly around important UI and targets. Make cleanup idempotent so reset, death, and pause cannot leak effects.
Verify
Test overlaps, multiple targets, rapid repetition, pause/resume, lowest quality, reduced motion, and touch viewports. Sample the live encounter for warnings, draw calls, frame time, and visual readability.
Trustgrade A
- passBody integrity
Whether the stored document is plausibly the kind of file the artifact declares, rather than something fetched by mistake.
- passType matchnot applicable to this artifact type
Whether the artifact is really the kind of thing its metadata claims it is.
- passFreshness
How long since the source repository was last pushed to.
- passPrompt injection
Scans the artifact's own text for instructions aimed at your agent rather than at you.
- passLicense
Whether the source repository declares an SPDX license permissive enough to redistribute.
How the grade is calculated
Each check contributes 0 points when it passes, 1 when it warns, and 2 when it fails. The total maps to a letter:
- Aevery check passed
- Bone warning
- Ctwo warnings
- Dprompt injection or body integrity failed, or three warnings
- Fone of those failed, and something else is wrong
These are automated hygiene checks, not a security audit, and not a dependency or vulnerability scan. A grade of A means nothing was flagged — not that the artifact is safe.
