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 | $0.00020 | $0.00278 |
| Opus 5 | $0.00010 | $0.00139 |
| Sonnet 5 | $0.00004 | $0.00056 |
| Haiku 4.5 | $0.00002 | $0.00028 |
Grade A, and why
typescript-conventions 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 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.
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
TypeScript conventions
Types
- Turn on
strictand keep it on. Fix type errors; don't paper over them. - Avoid
any. Reach forunknownat boundaries and narrow it, or write a proper type. Useascasts only when you truly know better than the compiler. - Model states with discriminated unions (
type Result = Ok | Err) instead of optional-field grab-bags. Let the compiler force you to handle every case. - Prefer
typealiases for unions and function types; useinterfacefor object shapes you expect to extend or implement.
Safety
- Don't abuse the non-null assertion
!. Handle theundefinedcase or narrow it. - Type function inputs and public return values explicitly; let inference handle local variables.
- Use
readonlyandas constfor data that shouldn't change.
Practical
- Derive types from a single source of truth (
typeof,keyof, indexed access, utility types) rather than hand-copying shapes. - Validate external data (API responses, env) at the boundary with a schema library so the rest of the code can trust its types.
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-conventions is a skill published in the GitHub repository Cypsy1714/cchad (1 stars, last pushed 2mo ago), licensed MIT. It adds 20 tokens to every session and 278 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 2026-08-31.
