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 | $0.00284 | $0.00284 |
| Opus 5.5 | $0.00114 | $0.00114 |
| Sonnet 5.5 | $0.00057 | $0.00057 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
hier_config 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.

Self-Review
Before opening or finalizing a PR, run the hier-config-review skill (/hier-config-review). It checks the diff against the repo's standards — models/typing, tests/TDD/coverage, changelog, docs, and driver patterns — and reports findings by severity.
Benchmarks
Performance benchmarks are in tests/test_benchmarks.py and are skipped by default via the benchmark pytest marker. They generate ~10,000-line configs and measure parsing, remediation, and iteration performance.
# Run all benchmarks with timing output
poetry run pytest -m benchmark -v -s
# Run a specific benchmark
poetry run pytest -m benchmark -k test_parse_large_ios_config -v -s
Use -s to see printed timing results. Each benchmark reports the best time over 3 iterations and asserts an upper bound (e.g., < 5s for parsing, < 10s for remediation). If a benchmark fails its time threshold, investigate the relevant code path for performance regressions.
After running benchmarks, always display the results to the user in a table format summarizing each benchmark's config size and elapsed time.
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.

hier_config CLAUDE.md is an instructions file published in the GitHub repository netdevops/hier_config (152 stars, last pushed 1mo ago), licensed MIT. It adds 284 tokens to every session, about $0.0011 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 2026-09-01.
