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 5.1 | $0.02350 | $0.02350 |
| Opus 5.5 | $0.00940 | $0.00940 |
| Sonnet 5.5 | $0.00470 | $0.00470 |
| Haiku 4.5 | $0.00235 | $0.00235 |
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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — Coding Conventions
Things You Will Get Wrong
- No enums, no namespaces —
erasableSyntaxOnlyis on. You will try to write enums. Don't. - No classes — use functions and plain objects. The only exception is
Errorsubclasses (they needinstanceofand 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 — alwaysimport from 'node:fs/promises', never bare'fs/promises'.import typefor type-only imports — enforced byverbatimModuleSyntax. You will forget this.- No
import type * asnamespace imports — import the specific types directly. If a type is reused across files in one top-level module, move it into that module'scommon/folder and import it from there. Do not reach fortypeof import('./foo')or module-wide type namespaces when a direct type import would tell the truth. catch (error: unknown)— neverany, never bareError.toStrictEqualovertoEqual— always. UsetoBefor primitives.- No
eslint-disablecomments — 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

index.tsat 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 incommon/.common/,utils/: named re-exports, no wildcards.utils/index.tsexports functions only; never re-export types there. Test-only folders (test/) have no barrels.

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.

agentic-mcp AGENTS.md is an instructions file published in the GitHub repository F0rty-Tw0/agentic-mcp (2 stars, last pushed 2d ago), licensed MIT. It adds 2,350 tokens to every session, about $0.0094 per session on Opus 5.5. 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.
