vibedoc: Instructions file for Codex

AGENTS.md

vibedoc AGENTS.md is an instructions file for Codex, OpenCode from quanghoangf/vibedoc. It costs 25 tokens per session, scanned A, original, MIT.

Project-specific instructions for quanghoangf/vibedoc, a tool for keeping local knowledge about a project available to AI-assisted development tools. The instructions point to CLAUDE.md, which contains the same information for compatibility with other coding tools.

In plain words
What is it for?
Use it when working on the vibedoc project and when instructions need to be shared across tools such as Cursor, Windsurf, Copilot Workspace, and Claude-based workflows.
Why use it?
It helps an agent follow the conventions and working context expected by that project instead of treating it like an unknown codebase.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md.

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

vibedoc 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 6d 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.

See CLAUDE.md — this file mirrors it for cross-tool compatibility (Cursor, Windsurf, Copilot Workspace).

Changes

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.
