no-vibe: Instructions file for Claude Code

AGENTS.md

no-vibe AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from rizukirr/no-vibe. It costs 1,677 tokens per session, scanned A, original, MIT.

Project instructions for no-vibe, a coding tutor that helps users learn by reviewing and guiding their code rather than writing project files during active sessions.

In plain words
What is it for?
Developing or reviewing no-vibe, especially its tutor-style behavior, guided coding flow, prediction checks, and write restrictions.
Why use it?
They give an AI agent the project rules, architecture, verification commands, and teaching principles needed to work on no-vibe correctly.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: PreToolUse hook event, but also the file is AGENTS.md. Also seen: names the NotebookEdit tool; mentions Codex; mentions Gemini CLI.

This is rizukirr/no-vibe's own configuration. It tells Claude Code, Codex and OpenCode how to work on no-vibe 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 no-vibe 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

no-vibe 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 7d 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.

Repo purpose

  • This repo is a plugin package (no-vibe) that enforces tutor-style coding: AI can teach/review, but should not write project files during active no-vibe sessions.
  • no-vibe is pure for learning. The plugin's goal is not just to make the user type the code — it is to make the user contribute the thought process behind it (deciding, predicting, naming what broke). Copy-typing AI output is the failure mode the design is built to prevent. Guided write (English-first walk with graded help verbs) is the default disclosure mode, and a one-question prediction gate runs before every Phase 3 run so the run becomes a self-test rather than passive verification. When changing teaching behavior, the test is: does this make the user contribute more of the thought process, or does it just make typing easier? The latter is a regression.

Architecture (high-signal files)

  • OpenCode plugin entrypoint: index.js re-exports .opencode/plugins/no-vibe.js.
  • Main OpenCode logic lives in .opencode/plugins/no-vibe.js:
    • injects no-vibe bootstrap into the first user message,
    • registers bundled skills path,
    • blocks write tools outside .no-vibe/ when .no-vibe/active exists.
  • Claude hook equivalent is hooks/block-writes.sh (PreToolUse for Edit/Write/NotebookEdit/MultiEdit/ApplyPatch) plus hooks/block-bash-writes.sh (PreToolUse for Bash).
  • Pi surface: .pi-plugin/plugin.json + .pi-plugin/extensions/no-vibe/index.ts (TS extension hooking before_agent_start for bootstrap injection and tool_call for write/Bash hard block) + .pi-plugin/prompts/no-vibe*.md. Mirror of the OpenCode plugin (hard block). Wired via the pi key in package.json.
  • Claude SessionStart hook hooks/status.sh prints no-vibe: ON|OFF — silent in projects without a .no-vibe/ dir to avoid noise elsewhere. OpenCode plugin and Pi extension mirror the same behavior in their bootstrap inject / before_agent_start injection.
  • Command specs are split by platform:
    • Claude-style command docs: commands/no-vibe.md, commands/no-vibe-challenge.md, commands/no-vibe-btw.md
    • OpenCode command docs: .opencode/commands/no-vibe.md, .opencode/commands/no-vibe-challenge.md, .opencode/commands/no-vibe-btw.md
    • Pi prompt templates: .pi-plugin/prompts/no-vibe.md, .pi-plugin/prompts/no-vibe-challenge.md, .pi-plugin/prompts/no-vibe-btw.md
    • Gemini CLI commands (TOML): .gemini/commands/no-vibe.toml, .gemini/commands/no-vibe-challenge.toml, .gemini/commands/no-vibe-btw.toml
  • Gemini CLI surface: gemini-extension.json + GEMINI.md + .gemini/tool-mapping.md. No PreToolUse hook equivalent — write guard is instruction-based (soft block); keep GEMINI.md guard rules aligned with hooks/block-writes.sh, .opencode/plugins/no-vibe.js, and .pi-plugin/extensions/no-vibe/index.ts behavior.

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.
