bluetemberg: Instructions file for Codex

AGENTS.md

bluetemberg AGENTS.md is an instructions file for Codex, OpenCode from prototypdigital/bluetemberg. It costs 1,004 tokens per session, scanned A, original, MIT.

Project instructions for Bluetemberg, a tool that creates and synchronizes AI-tool configuration for coding assistants.

In plain words
What is it for?
Use them when developing Bluetemberg, including building, testing, type-checking, formatting, or synchronizing settings for Cursor, Claude Code, and GitHub Copilot.
Why use it?
They explain the project's commands, file layout, and source-of-truth rules so contributors edit the right files and keep generated configurations consistent.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md; mentions Codex.

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

bluetemberg 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 2d 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bluetemberg

Distributes AI coding standards as versioned, integrity-verified npm packs, routed by team profile and stack version, and emits AGENTS.md plus native config for Cursor, Claude Code, GitHub Copilot, Gemini CLI (Enterprise), Antigravity CLI, Devin Desktop (formerly Windsurf), and OpenAI Codex. This repo is the engine; all content lives in bluetemberg-packs.

Commands

npm run dev          # TypeScript watch mode
npm run build        # Production build (tsc)
npm run test         # Run vitest
npm run test:watch   # Vitest in watch mode
npm run lint:fix     # ESLint auto-fix
npm run format       # Prettier format
npm run typecheck    # Type-check without emit
npm run sync:llm-config   # Sync rules -> all AI tool directories
npm run sync:catalog      # Refresh the committed catalog snapshot from the packs repo

AI Config Architecture

Source of truth for all AI tool configuration lives in llm/:

  • llm/rules/ — scoped rules (frontmatter: description, scope)
  • llm/agents/ — specialist agent definitions
  • llm/skills/ — on-demand skill workflows

Run npm run sync:llm-config to generate tool-specific files in .cursor/rules/, .cursor/agents/, .claude/, .github/instructions/, .github/agents/, .github/skills/, and related paths. These generated files should not be edited directly.

Project structure

  • src/init/ — Interactive wizard (prompts, presets, scaffold, switch-profile)
  • src/sync/ — Sync engine (config loading, frontmatter transforms, per-platform emitters, guardrails, hooks, marketplace, prune)
  • src/registry/ — Pack install/update/verify against the npm registry (auth, signatures, lockfile)
  • src/catalog/ — Catalog loader + committed snapshot (single source for pack ids/profiles)
  • src/stacks/ — Stack detection, version matching, coverage, org scanning
  • src/drafts/ — Human-gated create-loop: gap brief, draft skeletons, draft check, the draft promote gate, the draft: marker
  • src/sources/ — External rule sources (GitHub, PRPM, cursor.directory) and their translators
  • src/mcp/ — MCP server exposing detection/coverage tools, plus the MCP preset registry
  • src/preview/ — bluetemberg preview: what a profile would install
  • src/utils/ — Shared filesystem helpers
  • src/types.ts — All shared TypeScript types; src/help-json.ts — --help --json; src/cli-guards.ts — CLI flag validation
  • bin/cli.js — CLI entry point (Commander)
  • scripts/ — Maintainer scripts (sync-catalog, site build). This repo's own Claude Code hooks (PR review, session audit) come from the pr-review-loop and session-retrospective packs; see Contributing

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.
