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 AGENTS.md 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.

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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This repository is a monorepo shipping four Ruby gems around one format: okf, the baseline that reads, validates, lints, searches and serves Open Knowledge Format (OKF) v0.2 bundles, and three surfaces over it — an MCP shell, a terminal UI and an enforcement layer.

This file is context, routing and reference. It states what binds every change, points at where to read, and lists the commands. It explains nothing: the arguments live in the bundles, which are the harness a contributor works from. Start with the row for what you are changing.

Where to go

working on guide bundle
the baseline gem gems/okf/AGENTS.md okf search @okf <term>
the MCP shell gems/okf-mcp/AGENTS.md okf search @okf-mcp <term>
the terminal UI gems/okf-tui/AGENTS.md okf search @okf-tui <term>
the enforcement layer gems/okf-pro/AGENTS.md okf search @okf-pro <term>
the plugin, the skills, the resources, or anything binding all four this file okf search @okf-eco <term>

okf search @all <term> reaches every bundle at once; rake serve opens this repository's own as a graph.

What binds every change

Four rules to follow unprompted. The argument for each is one link away; these lines are the whole of what you must obey without reading it.

  • A change starts with a failing test, read failing, then the code, then the same test green and unedited. A bug report earns a red test before a patch.
  • Assertions must be able to fail for a real reason. Run the thing, read what it prints, assert that — never what you assume the code does.
  • The bundle ships in the same commit as the code it documents. A file under lib/ that no concept names is a red suite, not a stale document.
  • Don't improve adjacent code, and add no abstraction for single-use code. Match the surrounding style (.rubocop.yml — spaced brackets [ 1, 2 ], double quotes); remove only orphans your own change created.

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.
