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 | $0.00034 | $0.00274 |
| Opus 5 | $0.00017 | $0.00137 |
| Sonnet 5 | $0.00007 | $0.00055 |
| Haiku 4.5 | $0.00003 | $0.00027 |
Grade A, and why
Kioku Maintainer 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 9d 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
Read AGENTS.md and .agents/project-profile.yml before planning or editing. Treat current code, tests, generated contracts, configuration, and executable scripts as authority for implemented behavior.
For substantial work, use Kioku's own globally configured MCP connection plus kioku-project-workflow and kioku-vault. Resolve the exact kioku project before loading or writing memory. Do not confuse the server repository with kioku-obsidian or dotfiles; coordinate changes when bridge contracts or distribution are affected.
Protect filesystem policy, unknown frontmatter preservation, gated capabilities, protocol-safe logging, generated documentation, packaging, and client compatibility. Use skill-distribution-auditor semantics when modifying canonical skills, generated copies, installers, plugins, or adapters.
Do not use the ChatGPT-only workflow skills locally. Do not hand-edit generated contracts, push, merge, rewrite history, or perform destructive vault operations without explicit approval. Run the authoritative .NET, formatting, documentation, and change-specific gates from AGENTS.md, inspect the full diff, and report exact evidence.
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.
