kraken: Instructions file for Claude Code

AGENTS.md

kraken AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from rafael-adcp/kraken. It costs 2,061 tokens per session, scanned A, original, MIT.

Instructions for running an agent as a named worker, or “tentacle,” in Kraken, a system that coordinates queued tasks. They point the worker to the project's operating rules and execution procedure.

In plain words
What is it for?
Use them when contributing a worker to the Kraken task queue. They help the worker read the protocol and run each task transition through the supplied script.
Why use it?
They tell the worker which state rules, task-claiming steps, and delivery boundaries to follow when working without interactive supervision.

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

This is rafael-adcp/kraken's own configuration. It tells Claude Code, Codex and OpenCode how to work on kraken 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 kraken 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

kraken 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 27d 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — running as a kraken tentacle

This file lets an agents.md-aware agent CLI (GitHub Copilot CLI, and others that auto-load AGENTS.md) act as a kraken tentacle — a named worker draining the task queue in a kraken coordination repo — by reusing the reference worker skill rather than forking it. It is the second implementation whose existence proves the protocol is agent-agnostic: it carries no copy of the contract, and — since the worker skill became a loop around kraken.py next-action — no deltas either.

If you are a human or an agent contributing to the kraken codebase itself (not draining a queue), ignore this file and follow CONTRIBUTING.md.

Your operating contract — read these, then follow them

  1. PROTOCOL.md — the normative wire contract (kraken-protocol/9): the state record and the label state machine it projects, the hidden <!-- kraken {...} --> markers, the claim algorithm, delivery, and the authorization boundaries. Agent-agnostic already.
  2. skills/unleash/SKILL.md — how a worker executes that contract. Read it in full and follow it. Every transition runs through the bundled skills/unleash/kraken.py — the same program the Claude Code worker calls, driven by the same next-action loop.
  3. skills/unleash/DELIVERY.md — the delivery conventions SKILL.md points you at: branch naming, the attribution trailers, the draft PR, and Closes. It names your Co-Authored-By identity (Co-Authored-By: GitHub Copilot <[email protected]>) alongside Claude Code's.

You are invoked with the same three required arguments SKILL.md documents — the coordination repo slug OWNER/tasks, a --worker-name (an identity that says where the work ran, e.g. kraken-copilot-1), and a --project (only take project:<name> tasks).

Why there are no deltas any more

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.
