typescript-project

typescript-project is a skill for Claude Code, Codex from TasiTech/tasi-harness. It costs 17 tokens per session (110 once invoked), scanned A, original, MIT.

A workflow for building and maintaining strict TypeScript projects, including desktop and web applications. TypeScript is JavaScript with checks for data types and project structure.

In plain words
What is it for?
Use it to inspect project scripts and TypeScript settings, maintain typed code, add tests for reusable logic, and run type checks and tests.
Why use it?
It encourages early detection of type and integration errors and keeps the main application, secure preload layer, user interface, and shared types separated.

Token cost

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.

Security

Grade A, and why

typescript-project 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 6d 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 Project

Use this skill when working on TypeScript codebases.

Workflow

  1. Inspect package scripts and tsconfig files.
  2. Prefer strict types over any.
  3. Add unit tests for reusable logic.
  4. Run npm run typecheck and npm test when terminal access is enabled.
  5. Keep Electron main, preload, renderer, and shared types separated.

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.
