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 | $0.00024 | $0.00332 |
| Opus 5 | $0.00012 | $0.00166 |
| Sonnet 5 | $0.00005 | $0.00066 |
| Haiku 4.5 | $0.00002 | $0.00033 |
Grade A, and why
typescript 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 4d 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.
What it actually says
Components
- Use function components with typed props.
- Prefer
React.FConly when children typing is needed; otherwise avoid. - Memoize when beneficial (
React.memo,useMemo,useCallback).
Props & State
- Type props with interfaces or type aliases (PascalCase).
- Use
readonlyfor immutable props/state shapes. - Avoid
any; useunknownwhen necessary. - Prefer discriminated unions for state machines.
Hooks
- Extract logic into custom hooks.
- Type hook return values explicitly.
- Avoid unnecessary dependencies in hook arrays.
Data & Types
- Store types in
types.tsfiles. - Use Zod for runtime validation.
Imports & Exports
- Prefer named imports and named exports.
- Always declare imports at the beginning of source files.
- Import order:
- External libs
- Internal modules
- Types
- Avoid default exports.
Error Handling
- Use custom error classes with
codeand optional context. - Prefer
Result<T, E>patterns for recoverable failures.
Async Patterns
- Use
async/await. - Wrap async code with
try/catch. - Avoid inline Promises inside JSX.
Performance
- Use
as constfor literals. - Use mapped types for transformations.
- Use memoization and stable references to reduce re-renders.
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.

typescript is a skill published in the GitHub repository LedgerHQ/ledger-live (615 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 332 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
