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.

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 | $0.00058 | $0.00892 |
| Opus 5.5 | $0.00023 | $0.00357 |
| Sonnet 5.5 | $0.00012 | $0.00178 |
| Haiku 4.5 | $0.00006 | $0.00089 |
Grade A, and why
okf scanned grade A with 1 finding 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 1mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OKF bundle — Dribba
Open Knowledge Format
is Google Cloud's open specification (Apache 2.0) for shipping knowledge as a
directory of markdown files with YAML frontmatter. Dribba serves one at
https://dribba.com/okf.
Use it when you need Dribba's content as typed concepts you can traverse,
rather than as a flat text dump (/llms.txt) or as HTML you have to parse.
When to use this skill
Use it when you are ingesting the whole site in one pass and want stable,
typed markdown concepts with YAML frontmatter, traversable top-down through
index.md files.
It is overkill for a single page — use the markdown-negotiation skill — and the
wrong shape for structured records, which live in rest-api.
Layout
/okf → root index (same as /okf/index.md)
/okf/log.md → when the bundle was generated
/okf/company/… → Organization: identity, offices, contact
/okf/services/… → Service: one concept per service
/okf/cases/… → Case Study: challenge, solution, result, metrics, stack
/okf/articles/… → Article: full body of every blog post
/okf/jobs/… → Job Opening: description, requirements
/okf/pages/… → Web Page: every other public page, in markdown
Every directory has an index.md listing its concepts, so you can walk the
bundle top-down without knowing any filenames in advance. Start at /okf.
If you probe the .well-known convention instead, GET /.well-known/okf returns
a small JSON manifest naming bundle_root, and /.well-known/okf/<path> 308s to
the same path under /okf. The spec standardises neither, so the bundle has one
canonical root — https://dribba.com/okf — and that alias only points at it.
Reading a concept
curl -s https://dribba.com/okf/services/ai-integration.md
Each document opens with YAML frontmatter. type is the only field the spec
requires; Dribba also fills title, description, resource (the canonical
URL of the underlying page), sources, generated and tags. Links between
concepts are plain markdown links in bundle-absolute form (/cases/isdin.md),
so resolve them against https://dribba.com/okf.
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.

okf is a skill published in the GitHub repository dribbaengineering/dribba (0 stars, last pushed 2mo ago), licensed MIT. It adds 58 tokens to every session and 892 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
