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 | $0.01128 | $0.01128 |
| Opus 5 | $0.00564 | $0.00564 |
| Sonnet 5 | $0.00226 | $0.00226 |
| Haiku 4.5 | $0.00113 | $0.00113 |
Grade A, and why
deeptracer-js 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.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DeepTracer JavaScript SDK
AI-first observability SDK for JavaScript/TypeScript. Structured logging, error tracking, distributed tracing, and LLM usage monitoring.
Monorepo Structure
packages/
core/ — Zero-dependency shared core: Logger, transport, batcher, tracing, types
node/ — Node.js/Bun: global error capture, console capture, Hono & Express middleware
ai/ — AI SDK wrappers: Vercel AI SDK, OpenAI, Anthropic
browser/ — Browser: window error capture, console capture
react/ — React: provider, error boundary, hooks
nextjs/ — Next.js: one-file server + client instrumentation

- Target: ES2022
- Build order: core → node, ai, browser (parallel) → react → nextjs
Conventions
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.

deeptracer-js CLAUDE.md is an instructions file published in the GitHub repository getdeeptracer/deeptracer-js (5 stars, last pushed 3mo ago), licensed MIT. It adds 1,128 tokens to every session, about $0.0056 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.
