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

is-kit AGENTS.md 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.

Repository Guidelines

Project Structure & Modules

  • src/: Library source (TypeScript). Key areas:
    • core/: primitives and building blocks
      • guards: primitive.ts, object.ts
      • logic: logic.ts (and, andAll, or, not, guardIn)
      • equality: equals.ts (equals, equalsBy, equalsKey)
      • parsing: parse.ts (safeParse, safeParseWith)
      • nullability: nullish.ts (nullable, nonNull, nullish, optional, required)
      • helpers: define.ts, predicate.ts
      • combinators: core/combinators/* (arrayOf, tupleOf, oneOf, recordOf, struct, oneOfValues)
    • types/: shared type utilities
    • utils/: internal helpers (e.g., toBooleanPredicates)
    • Entry: src/index.ts re-exports public API (core, types, utils).
  • tests/: Jest runtime tests, mirroring src/ paths (e.g., tests/core/combinators/struct.test.ts).
  • tests-d/: tsd type tests, mirroring src/ paths (e.g., tests-d/core/combinators/struct.test-d.ts).
  • dist/: Build output (ESM .mjs, CJS .js, and .d.ts) generated by tsup.
  • Config: tsconfig*.json, tests/tsconfig.json, tests-d/tsconfig.json, tsup.config.ts, jest.config.cjs, .oxlintrc.json.

Build, Test, and Development

  • Install: pnpm install
  • Lint: pnpm lint — Oxlint over the repo.
  • Build: pnpm build — bundles via tsup to dist/ (ESM + CJS + types).
  • Test (runtime): pnpm test — runs Jest specs in tests/.
  • Test (types): pnpm test:types — runs tsd specs in tests-d/.

CI runs lint, build, unit tests, and type tests on PRs against main.

Coding Style & Naming

  • Language: TypeScript (strict: true). Target ES2022; outputs ESM/CJS.
  • Imports: use alias @/* for sources (e.g., import { struct } from '@/core/combinators').
  • Formatting: Oxfmt; 2-space indent; single quotes; semicolons.
  • Lint: Oxlint config in .oxlintrc.json. Project rules: complexity ≤ 7; no-unused-vars/no-undef warn; ignores dist/*.
  • Files: kebab-case for modules (core/combinators/tuple.ts), named exports; keep public API re-exported from src/index.ts.

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.
