vibe-stack: Instructions file for Codex

AGENTS.md

vibe-stack AGENTS.md is an instructions file for Codex, OpenCode from f-amine/vibe-stack. It costs 1,173 tokens per session, scanned C, original, MIT.

A set of project instructions for AI agents working on the Vibestack codebase. It explains setup, the development workflow, project limits, and where to find the relevant guides.

In plain words
What is it for?
It helps agents initialize the project, choose the right workflow for a task, read architecture decisions, and follow restrictions around code, dependencies, migrations, and documentation.
Why use it?
It gives an agent the project context and rules it needs before making significant changes. It also explains how the app behaves when optional configuration is missing.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is f-amine/vibe-stack's own configuration. It tells Codex and OpenCode how to work on vibe-stack 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 vibe-stack 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 C, and why

vibe-stack AGENTS.md scanned grade C with 1 finding 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.

Agents guide

vibestack is designed to be operated by AI agents in addition to humans. The skill workflow under .claude/skills/ is the canonical way to do non-trivial work.

First-time setup

If .env does not exist, run pnpm init:app (interactive wizard: product name rename, feature toggles, optional API keys, .env with a generated BETTER_AUTH_SECRET) or /setup in Claude Code for the conversational version — never read or print existing .env values. pnpm rename <name> does just the rename (lockfile-safe; run pnpm install after).

Zero-key boot: the app boots without any third-party keys — only DATABASE_URL + BETTER_AUTH_SECRET (+ URL vars) are required. Missing keys degrade or hide their feature: auth emails print to the dev console, billing doesn't mount without Polar, storage errors only when used without R2, /api/health reports them as disabled. See ADR-0009.

Workflow

Before doing anything non-trivial:

  1. Read CLAUDE.md, CONTEXT.md, and the relevant docs/adr/*.md.
  2. Pick the entry skill based on the kind of work:
    • New feature or capability — /grill-with-docs → /to-prd → /to-issues → /tdd → /review
    • Any frontend / UI change — /impeccable is mandatory before writing or editing component / page / styling code. Covers redesigns, new screens, "make this look better", spacing, colour, motion, copy, empty states. Holds even when the user did not name the skill. See ADR-0005.
    • Instagram Reels / short-form video / TikTok / YouTube Shorts — /video-writer. Swarm: researcher → script writer → [voice + SFX + music] parallel → motion designer → renderer → publisher. Reels are pure typographic / UI-mockup composition — no AI-generated stills on this surface. Output: 30-90s 9:16 MP4 + all assets under apps/marketing/public/reels/<slug>/. Remotion composition lives at packages/video/src/compositions/Reel.tsx. See ADR-0008.
    • Long-form blog posts / journal / content marketing — /blog-writer. Swarm: researcher → writer → (SEO editor + image producer in parallel) → publisher. 15-20 min read, multiple Gemini inline images, draft MDX in apps/marketing/content/blog/. See ADR-0007.
    • SEO / GEO / Search Console / organic traffic / keyword research / meta tags / schema / broken links / Core Web Vitals — route to toprank. Skills: /toprank:seo-analysis, /toprank:keyword-research, /toprank:content-writer, /toprank:geo-optimizer, /toprank:meta-tags-optimizer, /toprank:schema-markup-generator, /toprank:broken-link-checker, /toprank:seo-page. Uses live Google Search Console + PageSpeed Insights via OAuth. See ADR-0006.
    • Google Ads / Meta Ads / paid acquisition — also toprank. Skills: /toprank:google-ads-audit, /toprank:google-ads-manage, /toprank:google-ads-copy, /toprank:google-ads-landing, /toprank:meta-ads-audit, /toprank:meta-ads-manage. Connects via the NotFair-GoogleAds and NotFair-MetaAds HTTP MCPs in .mcp.json.
    • Bug report — /diagnose → /tdd
    • Refactor itch — /improve-codebase-architecture (requires maintainer approval; propose an ADR before changing structure)
    • Spike / design exploration — /prototype (throwaway, then formalise)
    • Triage — /triage for incoming issues
  3. Do not push code without an issue.

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.
