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 | $0.00455 | $0.00455 |
| Opus 5.5 | $0.00182 | $0.00182 |
| Sonnet 5.5 | $0.00091 | $0.00091 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade A, and why
fizzbee 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 2mo 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
Claude Code Instructions for Fizzbee
Build Commands
- Build the model checker:
bazel build //:fizzbee - Run the model checker:
./fizz path/to/spec/file.fizz(use the wrapper script, not the bazel binary directly)
Important Guidelines
- Do NOT use gazelle to update BUILD files
- The
./fizzwrapper script handles compilation and execution - always use it instead of./bazel-bin/fizzbee_/fizzbee
Testing
- Reference examples are in
examples/references/organized by feature - Many examples have
baseline.txtfiles for comparing output metrics (Nodes, Valid Nodes, Unique States, PASSED/FAILED status) - Generated files (
.jsonAST files andout/directories) can be deleted after testing
Running the test suite
python3 test_references.py
Runs all 94 reference examples (those with a baseline.txt) and all lovable specs in examples/requirements/lovable/. Compares output semantically (strips timestamps, elapsed times, file paths). Reports PASS/FAIL per example and a summary.
To update a baseline after an intentional change:
./fizz examples/references/NN-name/Spec.fizz > examples/references/NN-name/baseline.txt 2>&1

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.

fizzbee CLAUDE.md is an instructions file published in the GitHub repository fizzbee-io/fizzbee (366 stars, last pushed yesterday), licensed Apache-2.0. It adds 455 tokens to every session, about $0.0018 per session on Opus 5.5. 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 2026-08-30.
