Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00019 | $0.04258 |
| Opus 5 | $0.00010 | $0.02129 |
| Sonnet 5 | $0.00004 | $0.00852 |
| Haiku 4.5 | $0.00002 | $0.00426 |
Grade A, and why
animation-review 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 11d 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

Other skills, from other repositories
render-evidence
Capture the before/after rendered PNGs a UI-affecting PR in this repository needs as visual evidence, including bringing an Android SDK up in a fresh sandbox. Use when a change touches a Compose @Preview, a catalog, the VS Code webview, an overlay, a theme, an icon or a fixture, and the PR body needs real pixels.
devlab-web-test-e2e
A browser end-to-end testing skill for Vue and React applications. End-to-end testing checks a feature through the browser, from a user's actions to the resulting behavior, using Playwright.
visual-qa
Use when verifying that a UI renders correctly. Covers visual regression testing, responsive checks across breakpoints, cross-browser verification, and screenshot-based review of an implementation against a design.
test-strategy-document
Create a production-ready Testing Strategy and QA Execution Plan. Covers testing levels (unit, integration, E2E, performance), mocking boundaries, test environment matrix, code coverage thresholds, and automated CI pipeline runsheets. Use when establishing a QA framework for a new system or feature set.
frontend-visual-qa
Verify rendered frontend evidence after implementation, including screenshot comparison, responsiveness, overflow, visible states, and scoped visual regression. Use available browser tooling only; exclude static lookup, routine code review, lint, builds, onboarding, and tool detection.
