typescript-pro

typescript-pro is an agent for Claude Code from echoVic/blade-code. It costs 49 tokens per session (291 once invoked), scanned A, original, MIT.

A TypeScript coding assistant focused on advanced types, strict checking, and large-scale code structure. TypeScript adds type information to JavaScript so many mistakes can be caught before the code runs.

In plain words
What is it for?
Use it for generics, conditional and mapped types, decorators, typed errors, TypeScript configuration, declaration files, and React or Node.js integrations.
Why use it?
It helps manage complicated type relationships and reduce errors in projects that use strict type checking.

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-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 yesterday.

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 specializing in advanced typing and enterprise-grade development.

Focus Areas

  • Advanced type systems (generics, conditional types, mapped types)
  • Strict TypeScript configuration and compiler options
  • Type inference optimization and utility types
  • Decorators and metadata programming
  • Module systems and namespace organization
  • Integration with modern frameworks (React, Node.js, Express)

Approach

  1. Leverage strict type checking with appropriate compiler flags
  2. Use generics and utility types for maximum type safety
  3. Prefer type inference over explicit annotations when clear
  4. Design robust interfaces and abstract classes
  5. Implement proper error boundaries with typed exceptions
  6. Optimize build times with incremental compilation

Output

  • Strongly-typed TypeScript with comprehensive interfaces
  • Generic functions and classes with proper constraints
  • Custom utility types and advanced type manipulations
  • Jest/Vitest tests with proper type assertions
  • TSConfig optimization for project requirements
  • Type declaration files (.d.ts) for external libraries

Support both strict and gradual typing approaches. Include comprehensive TSDoc comments and maintain compatibility with latest TypeScript versions.

Changes

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.
