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 | $0.00043 | $0.02942 |
| Opus 5 | $0.00022 | $0.01471 |
| Sonnet 5 | $0.00009 | $0.00588 |
| Haiku 4.5 | $0.00004 | $0.00294 |
Grade A, and why
setup-okf-matt-skills 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 12d 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 — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Setup okf-matt-skills
Scaffold the per-repo configuration that the engineering skills assume:
- Issue tracker — where issues live (GitHub by default; local markdown is also supported out of the box)
- Triage labels — the strings used for the five canonical triage roles
- Domain docs — where the OKF knowledge bundle (
knowledge/) lives, and the consumer rules for reading it
All three land in the agent layer at knowledge/_agents/ — a reserved, _-prefixed
service directory inside the OKF bundle that holds agent-operational config and notes, and
is never a domain context (see "The agent layer" below).
This is a prompt-driven skill, not a deterministic script. Explore, present what you found, confirm with the user, then write.
Process
1. Explore
Look at the current repo to understand its starting state. Read whatever exists; don't assume:
git remote -vand.git/config— is this a GitHub repo? Which one?AGENTS.mdandCLAUDE.mdat the repo root — does either exist? Is there already an## Agent skillssection in either?knowledge/— the OKF knowledge bundle at the repo root (knowledge/glossary/,knowledge/adr/,knowledge/index.md), including any per-context subdirectoriesknowledge/_agents/— does this skill's prior output already exist? (Legacy repos may have it underknowledge/_agents/— an earlier layout; if you find that, migrate it toknowledge/_agents/as part of this run.).scratch/— sign that a local-markdown issue tracker convention is already in use
2. Present findings and ask
Summarise what's present and what's missing. Then walk the user through the three decisions one at a time — present a section, get the user's answer, then move to the next. Don't dump all three at once.
Assume the user does not know what these terms mean. Each section starts with a short explainer (what it is, why these skills need it, what changes if they pick differently). Then show the choices and the default.
What ships with it
6 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.
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.

setup-okf-matt-skills is a skill published in the GitHub repository evist0/okf-matt-skills (13 stars, last pushed 2mo ago), licensed MIT. It adds 43 tokens to every session and 2,942 once invoked, about $0.0002 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 2026-08-30.

openlore-brainstorm
Transform a feature idea into an annotated story using a Domain Sketch or Constrained Option Tree. Use when asked to brainstorm, explore, or shape a feature before implementation.
openlore-execute-refactor
Apply a confirmed .openlore/refactor-plan.md with a test gate after each change. Use when asked to execute or continue an OpenLore refactoring plan.
openlore-debug
Debug with OpenLore structural context, an explicit root-cause hypothesis, and RED/GREEN verification. Use when a bug, failure, or regression needs diagnosis and repair.
validate
Check that an Open Knowledge Format (OKF) bundle is conformant with the v0.2 spec (§11). Use when asked to validate, lint, or check an OKF bundle, or before committing changes to one. Runs a deterministic Python checker — not an eyeball pass. Also migrates a v0.1 bundle to v0.2 in place with --migrate.
