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 | $0.00805 | $0.00805 |
| Opus 5 | $0.00402 | $0.00402 |
| Sonnet 5 | $0.00161 | $0.00161 |
| Haiku 4.5 | $0.00081 | $0.00081 |
Grade A, and why
kiso 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 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.
This is a copy
95% identical to kiso copilot-instructions.md — 40 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.
How it starts

Project description
-
Kiso short description: Kiso is a publishing engine for Open Knowledge Format (OKF).
-
Kiso longer description: Kiso is a publishing engine that turns Open Knowledge Format (OKF) bundles into static websites for humans and AI agents.
-
Kiso complete description: Kiso is a publishing engine for the Open Knowledge Format (OKF). The project turns a folder of organized Markdown files into a navigable knowledge system. In the same way that Hugo turns Markdown files into a static website, Kiso aims to turn an OKF knowledge base into a structured, browsable, and usable documentation site. Kiso is also designed with AI usage in mind. Because the source remains structured Markdown, the knowledge base stays readable, versionable with Git, easy to review, and usable by AI agents. Kiso sits between two needs: simple text files for maintaining knowledge, and generated navigation for humans and tools to explore it.
-
Product analogy: Kiso is positioned as Hugo for Open Knowledge Format (OKF).
-
Open Knowledge Format description: Open Knowledge Format (OKF) is a way to structure knowledge using Markdown files enriched with metadata. The goal is to keep knowledge easy for humans to write and read, while making it structured enough for software tools and AI agents to understand, validate, connect, and reuse.

Open Knowledge Format (OKF) specification: /documentation/specs/okf_spec_version_0.1.md

Kiso features
Kiso-cli (/applications/kiso-cli) is a command-line application with commands such as:
format: Cleans Markdown files (e.g., removes unnecessary empty lines).validate: Checks that all files conform to the OKF specification.build: Generates a static website with HTML files alongside the original Markdown files.
Design principles
When generating code for this repository, always prioritize:
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.

kiso CLAUDE.md is an instructions file published in the GitHub repository oak-invest/kiso (39 stars, last pushed 3d ago), licensed Apache-2.0. It adds 805 tokens to every session, about $0.0040 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to kiso copilot-instructions.md, differing in 40 lines, and is treated as a copy.
