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 | $0.07263 | $0.07263 |
| Opus 5.5 | $0.02905 | $0.02905 |
| Sonnet 5.5 | $0.01453 | $0.01453 |
| Haiku 4.5 | $0.00726 | $0.00726 |
Grade A, and why
NornicDB AGENTS.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 4d 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

Target Audience: AI coding agents (Claude, GPT-4, etc.)
Coding and review principles
Read and apply the standing design principles while choosing a solution, writing code, and correcting code. Apply Rule 73 when corrections repeatedly fail or repeat an unsuccessful approach. Explicit user instructions take precedence over repository guidance.
Verification and review
- Lead proof with the requested product outcome, its supported conclusion, evidence, and practical limits. Verify the complete affected correction, including its public paths and consumers; a helper-only test does not establish that the public path reaches that helper.
- Establish the approved contract and preserve the original failing evidence. Distinguish an established defect from an unapproved precaution: reproducing an exceptional scenario does not by itself justify adding behavior.
- Scope regression checks to affected contracts and input boundaries. Do not claim broad correctness from statement coverage, static candidates, or a narrower input population.
- Review and verify the integrated current source. Related fixes tested in separate branches do not prove their combined implementation works. Evidence from changed source must have its continuing applicability established.
- Report what was actually checked, including failures, cancellations, cached results, skips and limitations. A canceled or superseded run is incomplete; cached evidence is not a fresh run.
- Follow the applicable checks and baselines in CONTRIBUTING.md. Do not weaken assertions, waive regressions, or substitute an unrelated benchmark to obtain a passing result.
- When a failure recurs, reassess the causal owner, approach and verification that missed it. Complete the integrated correction and its required review and proof before declaring the issue resolved.
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.

NornicDB AGENTS.md is an instructions file published in the GitHub repository orneryd/NornicDB (912 stars, last pushed today), licensed MIT. It adds 7,263 tokens to every session, about $0.0291 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.
