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 | $0.01316 | $0.01316 |
| Opus 5.5 | $0.00526 | $0.00526 |
| Sonnet 5.5 | $0.00263 | $0.00263 |
| Haiku 4.5 | $0.00132 | $0.00132 |
Grade A, and why
sniff 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 1mo 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project
Sniff
An autonomous QA scanner that walks your running app in a real headless browser, follows real user flows, and reports what is actually broken (broken pages, forms, accessibility, console errors, responsive issues), each with screenshot proof. The flow-walk is the default (sniff or sniff --url); sniff scan is the source-only mode. Distributed as an npm CLI and Claude Code plugin, with no API key required.
Core Value: One command finds bugs across every dimension (functional, visual, accessibility, performance) before users do, with no manual test writing, ever.
Constraints
- Tech stack: TypeScript + Node.js 22+ (locked decision)
- Test runtime: Playwright (chromium, webkit, firefox), a locked decision
- Default AI: Claude Code (no API key), the key differentiator, must work out of the box
- Distribution: npm-first (
npx sniff), the lowest-friction path for developers - Budget: Zero infrastructure cost for users, everything runs locally
- Performance: Must complete a scan of a medium app (50 routes) in under 10 minutes

Sniff contributor notes (portability and discoverability layer)
These notes record the gotchas introduced by the multi-CLI install and discoverability work. Keep them current when you touch the related files.
Host-agnostic agents
Sniff has no agents/ directory, so there is no model: frontmatter to strip. If agents are ever added, omit model: from their frontmatter so each host CLI falls back to its own default model. A literal model: inherit is a Claude-Code-only keyword that some hosts (for example OpenCode) reject as an unknown model id, which is why host-agnostic plugins carry only name and description.
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.
