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

agentic-mcp 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 5d 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.

AGENTS.md — Coding Conventions

Things You Will Get Wrong

  • No enums, no namespaceserasableSyntaxOnly is on. You will try to write enums. Don't.
  • No classes — use functions and plain objects. The only exception is Error subclasses (they need instanceof and stack traces).
  • No default exports — all exports are named, inline on the declaration.
  • No extensions on relative imports — use './foo', never './foo.ts' or './foo.js'. Package imports keep their original extension.
  • node: prefix mandatory — always import from 'node:fs/promises', never bare 'fs/promises'.
  • import type for type-only imports — enforced by verbatimModuleSyntax. You will forget this.
  • No import type * as namespace imports — import the specific types directly. If a type is reused across files in one top-level module, move it into that module's common/ folder and import it from there. Do not reach for typeof import('./foo') or module-wide type namespaces when a direct type import would tell the truth.
  • catch (error: unknown) — never any, never bare Error.
  • toStrictEqual over toEqual — always. Use toBe for primitives.
  • No eslint-disable comments — fix the code instead. Refactor to reduce complexity, extract helpers, restructure loops.
  • No JSDoc, no block comments (/* */), no commented-out code.
  • camelCase for local variables — never snake_case. Map to snake_case keys only at the object-literal boundary: { working_directory: workingDirectory }.

File & Naming

  • Files: kebab-case.ts with role suffix: .const.ts, .type.ts, .schema.ts, .handler.ts, .builder.ts, .util.ts.
  • Constants: SCREAMING_SNAKE_CASE. Types: PascalCase. Functions: camelCase.
  • Barrel index.ts at four levels:
    • Module root (ask/index.ts): wildcard re-exports from subdirs (export * from './common').
    • domain-logic/: named re-exports only — this is the module's public API surface for executable behavior. Export functions/constants only; reusable types belong in common/.
    • common/, utils/, stubs/: named re-exports, no wildcards. utils/index.ts exports functions only; never re-export types there.

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.
