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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00083 | $0.06461 |
| Opus 5 | $0.00042 | $0.03231 |
| Sonnet 5 | $0.00017 | $0.01292 |
| Haiku 4.5 | $0.00008 | $0.00646 |
Grade A, and why
product-instrumentation scanned grade A with 1 finding 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 3d 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.

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.

product-instrumentation is a skill published in the GitHub repository gamedevpl/www.gamedev.pl (15 stars, last pushed today), licensed GPL-3.0. It adds 83 tokens to every session and 6,461 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
bootstrap-game-qa-system
Use ONCE per browser-game project to set up the game-qa infrastructure. Copies the shipped runner template, the adapter skeleton, and the journey schema; gap-fills the project's existing debug system if one is present. Skip for non-game projects.
requesting-game-qa
Use ONLY for QA on browser-game feature work. Triggers when the engineer signals readiness for QA: "request QA on X", "verify X", "QA this", "ready for QA on X", "this should be ready, can we make sure it works?" Compiles a brief, drives test-plan sign-off, then hands off to game-qa. Skip for tooling, build scripts…
reviewing-game-qa
Use ONLY for browser-game QA. Dispatched by game-qa to validate a case-slice against an evidence bundle produced by running-game-qa-pass. Owns the case (not the script). Marks pass/softPass/fail/unverified-. Files tickets as findings emerge — does not batch. Leaf agent; spawns nothing.
running-game-qa-pass
Use ONLY for browser-game QA. Dispatched by game-qa to author and execute one journey covering a case-slice. Composes journey YAML (not Playwright JS), runs it via the project's runner, returns evidence-bundle pointers. Never judges results — that's the reviewer's job. Leaf agent; spawns nothing.
assets-get-data
Get asset data from the asset file in the Unity project — every serializable field and property. Supports token-saving path-scoped reads via paths or viewQuery. Use 'assets-find' to find the asset first.
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
