okf-bundle-gen

okf-bundle-gen is a skill for Claude Code, Codex from rhtevan/agentfs. It costs 18 tokens per session (6,502 once invoked), scanned A, original, Apache-2.0.

A tool that extracts useful knowledge from the current chat and agent memory files and saves it as an Open Knowledge Format (OKF) knowledge bundle. OKF is a structured collection of concept documents and indexes.

In plain words
What is it for?
Use it to create or merge knowledge documents under ~/.agents/knowledge/ and capture broader patterns from MEMORY.md and USER.md files.
Why use it?
It preserves important decisions, concepts, and patterns so they can be reused in later sessions instead of being lost in chat history.

Token cost

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.

Security

Grade A, and why

okf-bundle-gen 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 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/list-existing-concepts.sh, scripts/scan-memories.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

OKF Bundle Generation from Session Context

Scope guard: This skill is not available in LITE scope projects. LITE scope does not support skills or knowledge bundles. If the target project's AGENTS.md contains agentfs-scope: lite, refuse with a clear message.

Extract knowledge from the current chat session and persist it as an OKF v0.1 knowledge bundle under ~/.agents/knowledge/.

Additionally, scan all accumulated agent memories (MEMORY.md and USER.md files under ./.agents/) to extract higher-order patterns — abstract concepts that emerge from cross-session episodic observations. These patterns are written to a dedicated agent-patterns/ sub-bundle.

This skill is a knowledge-generation companion to okf-bundle-setup (which organizes existing files). Here the agent is the knowledge producer — it reads the conversation and memories, identifies concepts worth preserving, abstracts patterns from episodic observations, and writes (or merges) OKF-conformant concept documents.

For the full OKF specification, see load_skill(name: "okf-bundle-setup/references/okf-spec-summary.md").

Prerequisites

  • Write access to the working directory
  • The okf-bundle-setup skill must be available (its scripts are reused for scaffolding and verification)

Fixed Configuration

Setting Value
Bundle root ~/.agents/knowledge/
Session sub-bundle ~/.agents/knowledge/<session-name>/
Patterns sub-bundle ~/.agents/knowledge/agent-patterns/
Memories scan root ./.agents/
OKF version v0.1

The bundle root is not configurable — this skill always writes to ~/.agents/knowledge/ (the user-level knowledge directory).

Concept documents are never placed directly at the bundle root. Each invocation writes into a session sub-bundle — a subdirectory under the bundle root whose name represents the session's identity (see Phase 1). The root index.md and log.md serve as the top-level navigation and changelog across all session sub-bundles.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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-bundle-gen is a skill published in the GitHub repository rhtevan/agentfs (2 stars, last pushed 3d ago), licensed Apache-2.0. It adds 18 tokens to every session and 6,502 once invoked, about $0.0001 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 2026-08-31.
