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 | $0.00148 | $0.06049 |
| Opus 5.5 | $0.00059 | $0.02420 |
| Sonnet 5.5 | $0.00030 | $0.01210 |
| Haiku 4.5 | $0.00015 | $0.00605 |
Grade A, and why
typescript scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
const res = await fetch(url, { signal: AbortSignal.timeout(5000) }); How it starts
The opening of the file, as written. The whole thing — 489 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TypeScript (language skill)
This is a knowledge skill, not an agent: it loads from context whenever TypeScript or
JavaScript is written or reviewed, and the role agents (/fe, /be, /rev) route into
it for the language-level rules. Framework depth stays with /fe's stack references —
../../frontend/react/frontend-developer/SKILL.md and its
../../frontend/react/frontend-developer/references/react-expertise.md — while this file
owns TS-the-language, the Node runtime, package discipline, the lint/test toolchain, and
non-UI code: CLIs, servers, libraries, scripts.
Trigger
Use this skill when:
- Writing, editing, or reviewing
.ts,.tsx,.js, or.mjsfiles - Changing
tsconfig*.json,package.json, or a lockfile — flags, dependencies, exports, engines - Diagnosing a
tsc, ESLint, or Vitest failure - Designing a TypeScript component — module boundaries, error surface, async topology
- Planning tests for TypeScript code
- Adding a dependency to a JavaScript/TypeScript workspace
Do NOT load it for React/Next/Angular/Vue framework questions — those are /fe's stack
references — nor for E2E automation, which is /e2e's domain.
Context
This skill exists to make TypeScript reviews boring. The compiler is the first reviewer:
the type system exists to make illegal states unrepresentable, and the lint layer exists
to make forgotten awaits impossible, so humans review design instead of hunting typos.
Runtime trust starts at zero at every I/O edge — nothing crossing one is used before it
is parsed into a known type. Policy — compiler flags, lint severities, formatting,
dependency rules, coverage — lives in checked-in files, not in anyone's head, so "what
does this repo require?" has exactly one answer.
Documentation Lookup (MANDATORY)
Before implementing any feature, check current documentation. The TypeScript compiler line split in 2026, Node's LTS lanes rotate on a fixed calendar, and the package managers have tightened their security defaults at every major; recall is not a source.
What ships with it
1 file 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.

typescript is a skill published in the GitHub repository olehsvyrydov/AI-development-team (17 stars, last pushed today), licensed MIT. It adds 148 tokens to every session and 6,049 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-19.
