dakota: Instructions file for Codex

AGENTS.md

dakota AGENTS.md is an instructions file for Codex, OpenCode from projectbluefin/dakota. It costs 1,226 tokens per session, scanned A, original, MIT.

Project instructions for Dakota, Project Bluefin’s bootable Linux desktop image, built with BuildStream 2. They define safety rules, trusted sources of information, development steps, and architecture constraints.

In plain words
What is it for?
Use them when changing Dakota’s image definitions, build workflows, skills, architecture, or contribution process.
Why use it?
They prevent unsafe changes such as using the wrong package-building system, writing to protected repositories, exposing secrets, or pushing directly to protected branches.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is projectbluefin/dakota's own configuration. It tells Codex and OpenCode how to work on dakota 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 dakota 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

dakota 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 1mo 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.

Dakota agent guide

Dakota is Project Bluefin's bootc OCI desktop image, assembled from source with BuildStream 2. This is not the RPM-based Bluefin build: do not use dnf, rpm-ostree, COPRs, Containerfile package overlays, or post-build package installation. Make image changes through BST elements.

Project skills live in .agents/skills/ and are discovered by Pi and GitHub Copilot. Load only the skill matching the task; do not read every skill.

Factory model invariants

  • Scoped Documentation: Correct durable, task-relevant guidance when the work reveals an error or missing constraint. Do not manufacture documentation changes for every session or expand a read-only task into writes. Preparing changes does not authorize committing or publishing them.
  • Docs Are the Model: Skills and documentation are evergreen operating procedures. Never append dated session logs (2026-08-01: we found X), running issue numbers, or resolved checklists. Codify learnings as timeless architectural invariants and failure modes.
  • Documentation Freshness: Verify external syntax against current official documentation and cite the source when updating guidance. Context7 is optional when available; direct official documentation is equally valid. Do not require unavailable tools.

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.
