typescript-standards

typescript-standards is a cursor rule for Cursor from MrG4dget/5e-tools-mcp. It costs 0 tokens per session (102 once invoked), scanned A, original, MIT.

A rule set for writing TypeScript in the mcp-5etools project. It defines guidance for types, function design, utility code, formatting, and avoiding unnecessary refactoring.

In plain words
What is it for?
Use it when adding or changing TypeScript code in mcp-5etools, especially public APIs, rendering utilities, and tag-handling logic.
Why use it?
It reduces inconsistent code and helps prevent errors caused by loose types or unclear public interfaces.

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-standards 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 3d 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 Standards for mcp-5etools

  • Enable strict mode (see tsconfig.json).
  • Avoid any in public types; use precise interfaces and generics.
  • Favor small, composable functions with explicit return types for public APIs.
  • Prefer pure utilities in src/ for rendering logic and tag handling.
  • Match existing project formatting; avoid refactors that only change formatting.
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.
