Written for Claude Code and Codex and OpenCode: PreToolUse hook event, but also the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Codex.

This is pedroknigge/arkgate's own configuration. It tells Claude Code, Codex and OpenCode how to work on arkgate itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything arkgate configures →

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

arkgate 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 today.

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

ArkGate Enforcement (self-hosted)

Identity — read this first (every agent)

Git / clone only. This file is not published in the npm package. Consumers who npm install arkgate never see it. Do not copy this Identity block into generated consumer AGENTS.md, README, or other surfaces that ship with the library.

This working tree is the mother / canonical development repository for the ArkGate library.

Fact Meaning for you
What this is Source of truth for product ArkGate, npm package arkgate, dual CLIs arkgate* + ark*, MCP, published skills (templates/skills/), and the optional runtime kernel.
What this is not A normal app that depends on arkgate. Consumer monorepos (product apps, galleries, client projects) are downstream — never treat this tree as “just another project with arkgate installed.”
Where you are Library authoring root. Edits here ship (or dogfood) the package itself.
Contract shape Self-hosted 4-layer profile in ark.config.json (DomainModel / Kernel / Tooling / FrameworkAdapters) — not the default 11-layer consumer starter.
Dogfood Gates run on this tree via local bin/ + dist/ after npm run build. Prefer workspace CLIs over a stale global arkgate.

If the task is “improve arkgate the product,” you are in the right place. If the task is “adopt Ark on a business app,” you are usually in a different repository that lists arkgate as a dependency.


Project knowledge map

Code and manifests are the source of truth for implementation details and for whether a structural claim is true. Documentation is organized in three public lanes — use the map, not every historical file:

Lane Entry Audience
Use docs/use.md Anyone shipping with AI
Develop docs/develop.md Integrate gates, hosts, CI, brownfield
Contribute CONTRIBUTING.md Improve this library

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.
