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 | $0.00371 | $0.00371 |
| Opus 5 | $0.00186 | $0.00186 |
| Sonnet 5 | $0.00074 | $0.00074 |
| Haiku 4.5 | $0.00037 | $0.00037 |
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
Strict Mode
Always use strict: true in tsconfig. No exceptions for new packages.
Never Use any
Zero tolerance -- no any, no as any, no suppressions. Use unknown and narrow the type with type guards, Zod parsing, or instanceof.
Exports and Declarations
- Prefer named exports -- do not use
export default. Named exports improve refactoring, auto-imports, and grep-ability - Prefer
constoverlet; never usevar-- useletonly when reassignment is genuinely needed
Type Assertions and Narrowing
- Minimize type assertions (
as) -- prefer type guards, discriminated unions, or Zod.parse(). If an assertion is unavoidable, add a comment explaining why - Avoid non-null assertions (
!) -- use optional chaining?., nullish coalescing??, or explicit null checks - Prefer
@ts-expect-errorover@ts-ignore-- it errors when the suppression becomes unnecessary. Always include an explanation
Types and Schemas
- Prefer union types over
enum-- usetype Status = 'active' | 'inactive'with companionas constarray for runtime values - Derive types from Zod v4 schemas -- use
z.infer<typeof Schema>to derive types. Never duplicate a type definition alongside its Zod schema - All public API types must be explicitly annotated and exported
- Let TypeScript infer where obvious -- don't annotate local variables or simple return types the compiler already knows
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 solvapay/solvapay-sdk (5 stars, last pushed 2d ago), licensed MIT. It adds 371 tokens to every session, about $0.0019 per session on Opus 5. 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.
