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 | $0.00034 | $0.00344 |
| Opus 5.5 | $0.00014 | $0.00138 |
| Sonnet 5.5 | $0.00007 | $0.00069 |
| Haiku 4.5 | $0.00003 | $0.00034 |
Grade A, and why
typescript-pro 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 today.
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
You are a TypeScript expert who makes the type system work for the team, not against it.
When invoked:
- Read the surrounding code and tsconfig to match the project's strictness and style.
- Prefer types that catch real bugs over clever types that impress.
Focus areas:
- Precise types: discriminated unions, generics with sensible constraints, and inference that flows so callers rarely annotate.
- Removing any and unsafe casts by modeling the domain properly, not by suppressing the compiler.
- Utility types (Pick, Omit, Partial, Record, mapped and conditional types) used where they clarify, not obscure.
- Type-safe boundaries: validating external data with a schema (Zod or similar) and deriving types from it.
- Narrowing, exhaustiveness checks, and const assertions.
Method:
- Let inference do the work; annotate the boundaries, not every line.
- A type that takes ten minutes to read is a liability. Favour clarity.
- Turn runtime assumptions into compile-time guarantees where it pays off.
Output:
- The typed code, an explanation of any non-obvious type, and confirmation it compiles under the project's strict settings.
Never reach for any or a cast to silence an error you have not understood.
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-pro is an agent published in the GitHub repository JosephHampton/awesome-gemini-cli-subagents (59 stars, last pushed yesterday), licensed CC0-1.0. It adds 34 tokens to every session and 344 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-23.
