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 | $0.00535 | $0.00535 |
| Opus 5 | $0.00267 | $0.00267 |
| Sonnet 5 | $0.00107 | $0.00107 |
| Haiku 4.5 | $0.00053 | $0.00053 |
Grade A, and why
frontend-template AGENTS.md 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 2d 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.

Naming
camelCase functions/hooks · PascalCase components · kebab-case other folders/assets.
Components
Encapsulate · minimize files · mirror tree. Named exports only — no React.FC.
Keep ComponentName.tsx / FeatureName.tsx UI-only — types in *.types.ts, constants in *.constants.ts.
No inline display strings — copy in locale catalogs or constants (project chooses).
Merge classes with cn(...) — no Tailwind string-ternary classNames.
Semantic HTML + keyboard-accessible interactive UI.
Hooks & effects
One responsibility per hook. Prefer derived values over mirrored state.
useEffect: named inner function; complete dependency arrays.
Tests
BDD Given/When/Then. Unit colocated. E2E happy paths only. Prefer getByRole queries.
DoD
Biome + types clean · tests updated · Zod on API responses · a11y for new UI · no inline display strings (locales or constants) · cn for classes · CI green.
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.

frontend-template AGENTS.md is an instructions file published in the GitHub repository ddebixx/frontend-template (3 stars, last pushed 24d ago), licensed MIT.
