why this exists

The web’s next reader isn’t human.

Every era rewrote knowledge for its reader — pages for eyes, apps for thumbs, concepts for agents. OKF is the format of that layer; okfhub is its registry — where agents discover, verify and install expertise.

Expertise, packaged for agents.

A knowledge bundle is a portable collection of linked concepts — plain Markdown with structured metadata. Humans can read it. Agents can consume it. Git can version it.

Skills are verbs. Bundles are nouns.

Skills change what an agent does, for one harness. Bundles change what it knows. They’re complementary — skills give capabilities; bundles give those capabilities domain context.

freshness

Install expertise. Keep it current.

Your API changes. Your policies change. A useful bundle isn’t a document you publish once — it’s maintained expertise that evolves with the domain. Installs pin an exact SHA, okfhub update shows drift before changing a thing, and updates never delete your edits.

Non-destructive by design — install & update details →

lifecyclemaintained, not archived

sha pinned at install — never floats

update --dry-run lists drift, changes nothing

the knowledge stays fresh, not snapshotted

trust

Don’t trust the registry. Verify the source.

okfhub doesn’t decide whether knowledge is trustworthy. It gives agents evidence they can evaluate — dated, re-checkable, never a verdict.

for organizations

Your knowledge has a new audience.

Your agents

Give internal agents a canonical source of organizational knowledge.

Your customers’ agents

Let agents acting on behalf of your customers understand your products, policies and APIs directly.

Your developers

Portable, versioned knowledge instead of another proprietary documentation system.

Your business

Understand how agents discover and use your expertise — agent analytics, later.

Later is a thesis about where the agent web is going — not a promise.

The web was built for people.
Knowledge can now speak to agents.
