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 | $0.00443 | $0.00443 |
| Opus 5 | $0.00221 | $0.00221 |
| Sonnet 5 | $0.00089 | $0.00089 |
| Haiku 4.5 | $0.00044 | $0.00044 |
Grade A, and why
rumble-mcp CLAUDE.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 8d 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
Rumble MCP — AI Agent Rules
This file is loaded automatically by Claude Code and other AI coding tools. Follow all rules below without exception.
TypeScript Quality Rules
- No
anytypes — Always use proper TypeScript interfaces. If the API shape is unknown, define a minimal interface based on observed fields. The ESLint rule@typescript-eslint/no-explicit-anyis set toerror; the build will fail if you introduceany. - Type imports — Use
import typefor type-only imports (e.g.,import type { Foo } from './foo.js'). - No silent error swallowing — Every
catchblock must either log the error or re-throw it. Emptycatch {}blocks are forbidden.
Testing Rules
- Tests required for new code — Every new function or module must have corresponding unit tests. Target 80%+ coverage on new code.
- Run validation before committing — Always run
npm run validate(lint + format + typecheck + test) before any commit.
Architecture Rules
- Follow existing patterns — New tools must follow the existing tool module pattern (schema + handler). Check
src/tools/fundamental.tsas the reference implementation. - Prefer editing existing files — Don't create new files unless the feature genuinely requires a new module.
- No hardcoded secrets or API keys — Use environment variables exclusively. Reference
.env.examplefor required vars.
Git Rules
- Conventional commits — All commits must use conventional commit format:
feat:,fix:,refactor:,chore:,docs:,test:, etc.

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.
