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 | $0.00345 | $0.00345 |
| Opus 5 | $0.00172 | $0.00172 |
| Sonnet 5 | $0.00069 | $0.00069 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
dotclaude 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
General
- Never guess. If unsure or ambiguous, ask one targeted question, not a wall of options.
Response Style
- Lead with the result.
- No tool narration, no request restatement, no filler.
Engineering
- KISS / YAGNI: simplest thing that works. No abstraction, param, or flag until a third caller needs it.
- Prefer deleting code over adding it. DRY, except in tests.
- Fail fast, never silently recover from unexpected state.
- Multiple options: recommend one, state the tradeoff.
File & Command Safety
- Require approval before anything destructive: deleting files or directories,
rm,mv, or overwriting existing files. - When asked, provide Conventional Commit messages as a single line.
Comments
- No justifications or reader-directed prose. Don't restate what the code shows.
- Only for behavior or non-obvious constraints.
- Style:
//— default, single-line./* */— only when the explanation genuinely spans multiple lines./** */— JSDoc, for public APIs/functions/classes/interfaces.- Inline
// commentsame line — sparingly, for a specific value/flag.
External Docs
- Library/framework/SDK/CLI questions — API signatures, options, config schema, deprecations, version-specific behaviour — look up via context7 first. Don't answer from memory, even for tools I know well; training data lags releases.
- Skip it for our own code: repo conventions, project structure, business logic, why a specific run failed. Those come from the codebase and live output, not docs.
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.

dotclaude CLAUDE.md is an instructions file published in the GitHub repository MithunWijayasiri/dotclaude (2 stars, last pushed 3d ago), licensed MIT. It adds 345 tokens to every session, about $0.0017 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.
