What it does
Typescript Core is an agent skill from bobmatnyc/claude-mpm. Advanced TypeScript patterns and best practices for 2025
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `.etag_cache.json`, `metadata.json` and `references/.etag_cache.json`).
It sits in Frontend & Design, covering Forms and validation. It works with TypeScript and Zod. The repository describes itself as: Claude Multi-Agent Project Manager — multi-channel orchestration, GitHub-first SDK mode, and plugin system for Claude.
When your agent uses it
- Tasks that involve Forms and validation
Example prompts
- “/typescript-core”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 25203d3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript and json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Typescript Core loads about 2.2k tokens when it runs, and up to ~22k if it reads all its reference files. Until then it costs about 18 tokens; SKILL.md has 626 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 626 words (~2,220 tokens).
“Modern TypeScript development patterns for type safety, runtime validation, and optimal configuration.”
