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 | $0.00207 | $0.00207 |
| Opus 5.5 | $0.00083 | $0.00083 |
| Sonnet 5.5 | $0.00041 | $0.00041 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
okf-rs 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 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.
This is a copy
100% identical to okf-rs copilot-instructions.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Knowledge base
This project's structural knowledge — modules, types, functions, and their call graph — is available as an OKF bundle in knowledge/. It's plain markdown with YAML frontmatter; browse knowledge/index.md for an overview, or query it with the CLI:
okf-rs search <query>— find a symbol, type, or module by name or tagokf-rs graph callers <id>/okf-rs graph callees <id>— trace the call graph from a concept id (ids are shown bysearch)okf-rs graph api— list the public API surfaceokf-rs graph cycles— list call-graph cycles
Regenerate the bundle after code changes with okf-rs generate.
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.
