Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00082 | $0.01878 |
| Opus 5 | $0.00041 | $0.00939 |
| Sonnet 5 | $0.00016 | $0.00376 |
| Haiku 4.5 | $0.00008 | $0.00188 |
Grade A, and why
open-knowledge-format 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.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Open Knowledge Format (OKF) — v0.1
Google Cloud published the Open Knowledge Format v0.1 on June 12, 2026 — an open specification that formalizes the LLM-wiki pattern into a portable, vendor-neutral format for AI agent knowledge.
The design is intentionally minimal: a directory of markdown files with YAML frontmatter. No schema registry, no central authority, no required tooling.
"If you can
cata file, you can read OKF; if you cangit clonea repo, you can ship it."
Core Concepts
| Concept | Definition |
|---|---|
| Knowledge Bundle | A self-contained directory tree of markdown files. The unit of distribution. |
| Concept | A single unit of knowledge — one markdown file. May describe a table, a metric, a playbook, an API, or any idea. |
| Concept ID | The file path with .md stripped (e.g. tables/users.md has ID tables/users). |
| Frontmatter | YAML block at the top of each file with structured metadata. |
| Body | Standard markdown content after the frontmatter. |
| Link | A markdown link from one concept to another — expresses relationships. |
Reference Files
| Reference | Load when | File |
|---|---|---|
| Spec summary | You need the full OKF v0.1 specification, conformance criteria, and field definitions | references/spec-summary.md |
| Bundle architecture | You're creating or structuring an OKF bundle — directory layout, index files, cross-linking conventions | references/bundle-architecture.md |
| Use cases | You need real-world examples, third-party implementations, and adoption patterns | references/use-cases.md |
Scripts
| Script | Purpose | Load when |
|---|---|---|
okf-bundle-validate.py |
Validate an OKF bundle directory — checks frontmatter, required fields, reserved filenames, and cross-link integrity | You've created or modified an OKF bundle and want to verify conformance |

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.

open-knowledge-format is a skill published in the GitHub repository magnus919/agent-skills (76 stars, last pushed yesterday), licensed MIT. It adds 82 tokens to every session and 1,878 once invoked, about $0.0004 per session on Opus 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 2026-09-03.
