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 | $0.02147 | $0.02147 |
| Opus 5 | $0.01073 | $0.01073 |
| Sonnet 5 | $0.00429 | $0.00429 |
| Haiku 4.5 | $0.00215 | $0.00215 |
Grade A, and why
dox-cc 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 12d 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 — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DOX framework (Claude Code rules edition)
- DOX is a highly performant instruction hierarchy for Claude Code
- The root contract is this file:
CLAUDE.mdat the repository root (auto-loaded by Claude Code) - Domain-specific instructions live in
.claude/rules/as path-scoped rule files - Agent must follow DOX instructions across any edits
Doc Layout
- Root contract:
CLAUDE.md(repository root, this file) — global rules, durable workflow, Rules Index - Domain rules:
.claude/rules/<domain>.mdwith YAMLpaths:frontmatter scoping them to project globsservices/→.claude/rules/services.mdwithpaths: ["services/**"]models/→.claude/rules/models.mdwithpaths: ["models/**"]- cross-cutting concerns may use extension globs, e.g.
.claude/rules/tests.mdwithpaths: ["**/*.test.ts"]
- Subfolders inside
.claude/rules/are allowed for organization (e.g..claude/rules/services/auth.md) - Rules without a
paths:field load unconditionally; use them only for truly global concerns — prefer this root file instead - Never create CLAUDE.md files inside project source directories; this root file is the only CLAUDE.md
Rule File Shape

paths:
- "services/auth/**"

# Auth Service Rules
## Purpose
## Local Contracts
## Work Guidance
## Creation Conventions
## Verification
paths:globs must be quoted when starting with{or*- Work Guidance must reflect current project standards; if none exist yet, leave it empty
- Verification must reflect an existing check; if none exists yet, leave it empty and update it when one exists
- Creation Conventions lists rules that must hold when NEW files are created in scope (see Known Engine Limits)
Core Contract
- This root file and every applicable rule file are binding work contracts for their scopes
- Work products, source materials, instructions, records, assets, and durable docs must stay understandable from the root contract plus every rule whose
paths:covers them - If docs conflict, the path-scoped rule controls local work details, but no rule may weaken DOX
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.

dox-cc CLAUDE.md is an instructions file published in the GitHub repository wojciech-zurek/dox-cc (1 stars, last pushed 3mo ago), licensed MIT. It adds 2,147 tokens to every session, about $0.0107 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.
