OKF for Cursor — Using Knowledge Bundles in Cursor
Give Cursor portable, model-agnostic knowledge bundles — not just behavior rules.
What Is OKF (in 30 Seconds)?
Open Knowledge Format (OKF) is an open standard for packaging knowledge as structured markdown that AI agents can consume. An OKF bundle is a directory of plain-text documents — a manifest, concept notes, guides, and references — all cross-linked and validated. It launched in mid-2026 and is model-agnostic: any capable coding agent, including Cursor, can read it.
Think of OKF as portable knowledge you can drop into any tool, versus Cursor Rules which are behavior instructions scoped to a single editor.
Why Cursor Users Need Knowledge Bundles
Cursor is great at editing code, but it only knows what you give it. Large, well-organized knowledge — library docs, domain concepts, onboarding material, architecture decisions — is tedious to feed by hand. OKF bundles let you load that once, in a structured way Cursor can browse.
- Depth — A bundle holds far more than a short rule file (full docs, references, decision records).
- Reusability — The same bundle works in Cursor, Claude Code, OpenCode, and plain LLM chat.
- Structure — Cursor can follow cross-links between documents instead of guessing.
- Freshness — Update the bundle once; Cursor picks up the changes.
Cursor Rules vs OKF
| Cursor Rules (.cursor/rules) | OKF Bundles | |
|---|---|---|
| Purpose | Behavior & style instructions for the editor | Portable knowledge & documentation |
| Scope | Project / editor-specific | Model-agnostic, reusable anywhere |
| Size | Short instruction files | Deep, structured document sets |
| Format | .mdc / markdown | Markdown directory + manifest + validation |
| Best used for | How Cursor should behave | What the codebase / domain is |
They're complementary. Use Cursor Rules for behavior, OKF bundles for knowledge — and reference the bundle from a rule file so Cursor loads both.
How to Load an OKF Bundle in Cursor
1. Clone a Bundle into Your Project
Head to the BundleDex directory, find a bundle you want, and clone it into your repo:
# Clone an OKF bundle into your project
git clone https://github.com/iwe-org/iwe.git .okf/iwe
# Structure of an OKF bundle:
# index.md # manifest (required)
# concepts/*.md # domain knowledge
# guides/*.md # how-tos
# references/*.md # reference docs 2. Point Cursor at It via Rules or AGENTS.md
Add a reference in a .cursor/rules file or your AGENTS.md so Cursor knows the bundle exists:
# .cursor/rules/okf-agent.mdc

description: Load OKF knowledge bundles for context
globs: **/*
---
When answering questions about the domain, read from .okf/iwe/concepts/ as needed.
Start with index.md to understand the structure. 3. Ask Cursor to Use It
In chat or Composer, prompt: "Read .okf/iwe/index.md, then use the concepts in the bundle to answer my question." Cursor will follow cross-links and pull the relevant documents.

Create Your Own OKF Bundle for Cursor
You can also package your team's knowledge as an OKF bundle so Cursor (and every other agent) can consume it. The basics:
- Create an
index.mdmanifest with frontmatter (type, description, tags). - Add
concepts/,guides/, andreferences/as markdown. - Validate conformance with a tool like okf-builder or the OKF CLI.
- Submit it to BundleDex so other Cursor users can find it.
FAQ
Can I use OKF bundles in Cursor? Yes — they're plain markdown directories, so you can load them via project rules, AGENTS.md, or by pasting docs into chat.
What's the difference between OKF and Cursor Rules? Cursor Rules set behavior; OKF bundles carry portable knowledge. Use both together.
How do I load an OKF bundle in Cursor? Clone it, reference it from a rule or AGENTS.md, and prompt Cursor to read index.md first.
Is OKF compatible with AGENTS.md in Cursor? Yes — point your AGENTS.md at the bundle and the two load together.
