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.

What it costs to keep this loaded
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 | $0.00041 | $0.00714 |
| Opus 5 | $0.00020 | $0.00357 |
| Sonnet 5 | $0.00008 | $0.00143 |
| Haiku 4.5 | $0.00004 | $0.00071 |
Grade A, and why
typescript-tooling 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 13d 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.

TypeScript Tooling
Priority: P1 (HIGH)
Implementation Guidelines
- Compiler: Use
tscfor CI builds;esbuildorts-nodefor development. - Linting: Enforce
ESLintwith@typescript-eslint/recommended. Enable strict type checking. - Formatting: Mandate
Prettiervialint-stagedand.prettierrc. - Testing: Use
Vitest(orJest) for unit/integration testing. Target > 80% line coverage. - Builds: Use
tsup(library bundling) orVite(web applications). - TypeScript Config: Aim for
strict: truelong-term. For existing projects, migrate incrementally: start withstrictNullChecks, thennoImplicitAny,strictFunctionTypes. Do NOT flipstrict: truein one step. - CI/CD: Always run
tsc --noEmitin build pipeline to catch type errors. - Error Suppression: Favor
@ts-expect-errorover@ts-ignorefor documented edge-cases.
ESLint Configuration
Enable @typescript-eslint/recommended at minimum. When strict: false in tsconfig, no-unsafe-* rules may produce excessive noise — suppress selectively with @ts-expect-error rather than disabling globally.
See reference for common linting issues (request typing, unused params, test mock typing) and tsconfig migration examples.
Verification Workflow (Mandatory)
After editing any .ts / .tsx file:
- Call
getDiagnostics(typescript-lsp MCP tool) — surfaces type errors in real time. - Run
tsc --noEmitin CI — catches project-wide errors LSP may miss. - Run
eslint --fix— auto-fix formatting and lint violations.
Fallback when typescript-lsp MCP unconfigured: run
tsc --noEmitdirectly.
getDiagnostics fastest feedback loop. Use it before every commit on modified files. Use getHover to inspect inferred types, getReferences before renaming symbols.
Anti-Patterns
- No
@ts-ignore: Use@ts-expect-error— self-documents intent, fails if error disappears. - No
anyfor request objects: Import centralized interfaces fromsrc/common/interfaces/. - No
eslint-disable(global): Suppress per-line; fix root cause instead. - No atomic
strict: trueflip on existing repos: migrate incrementally starting withstrictNullChecks.
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-tooling is a skill published in the GitHub repository HoangNguyen0403/agent-skills-standard (565 stars, last pushed 3d ago), licensed MIT. It adds 41 tokens to every session and 714 once invoked, about $0.0002 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.
