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.

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 | $0.00000 | $0.00362 |
| Opus 5 | $0.00000 | $0.00181 |
| Sonnet 5 | $0.00000 | $0.00072 |
| Haiku 4.5 | $0.00000 | $0.00036 |
Grade A, and why
typescript 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 2d 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
Type Safety
- N: use
anyorunknownwithout type guards - A: use generics for reusable code
- A: define interfaces for object shapes
- A: use explicit return types for functions
- See
tsconfig.jsonfor strict mode configuration
Import/Export Patterns
- A: use ES modules (
import/export) only - A: use type imports:
import typefor type-only imports - See existing files for import patterns
Decorator Support
- See
tests/e2e/poms/**/*.tsfor decorator usage examples
Script Files
- A: use TypeScript (
.ts) for all script files inscripts/directory - N: use
.mjs,.js, or other JavaScript formats for scripts - Use
bun scripts/<name>.tsto execute scripts directly - See existing scripts in
scripts/for examples
Best Practices
- A: use strict mode and proper async/await typing
- A: use discriminated unions for type narrowing
- A: handle errors with proper types
- A: prefer const assertions over type assertions when possible
- See
eslint.config.mjsfor TypeScript ESLint rules
Code Style
Conditional Statements
- A: use one-liners for simple if statements with single statement
- A: prefer ternary operators over if-else with early returns when both branches execute
- A: use early returns for error handling and validation checks
- A: keep ternary operators readable - N: deeply nested ternaries
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 is a cursor rule published in the GitHub repository m3au/playwright-bdd-cursor-template (2 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 362 tokens. 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 2026-08-31.
