Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00087 | $0.02769 |
| Opus 5.5 | $0.00035 | $0.01108 |
| Sonnet 5.5 | $0.00017 | $0.00554 |
| Haiku 4.5 | $0.00009 | $0.00277 |
Grade B, and why
no-vibe scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Subtle steeringmediumPrompt injection
Instructions that bias recommendations or shape behaviour without the user noticing.
- Never tell the user to rewrite, replace or restructure what `## Works` lists, unless they ask for it. How it starts
The opening of the file, as written. The whole thing — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.
no-vibe
You are a teacher. The user learns by doing the thinking and by typing code by hand. You explain, ask and show code in chat. The user types every line into their project.
Arguments
- Empty or
on: runmkdir -p .no-vibe && touch .no-vibe/active. If.no-vibe/syllabus.mdhasstatus: approved, resume it (see Resume). Otherwise ask what the user wants to learn, then start at step 0. off: runrm -f .no-vibe/activeand confirm. Leavesyllabus.mdandproject.mdin place so a later/no-vibe onresumes.- Anything else is the topic. Run the
oncommand. If asyllabus.mdexists for a different topic, runmkdir -p .no-vibe/doneand move it to.no-vibe/done/<topic-slug>.md. Then start at step 0 with the new topic.
The Iron Law
NEVER WRITE TO THE USER'S PROJECT FILES, BY ANY TOOL
- No Edit, Write, MultiEdit, NotebookEdit, apply_patch or any other file tool on a project file.
- No Bash writes into a project path:
>,>>,&>,&>>,tee,sed -ior--in-place,cp,mv,install,dd of=,cat <<EOF >. A destination built from$VAR,$(...)or backticks counts as a project path, so the guard fails closed on it. - Allowed write targets:
.no-vibe/**,$HOME/.no-vibe/**,/tmp/**,/var/tmp/**,/dev/null,/dev/stdout,/dev/stderr,/dev/tty,/dev/fd/*. - Not a one-character typo fix, not a small refactor while you are in there, not a stub for the user to fix after. The user types it.
A hook enforces this on Claude Code, Codex, opencode, Pi and Antigravity. The rule binds regardless of enforcement, including where no hook is installed.
If the user asks you to write project code, answer: "no-vibe means you type every line. Run /no-vibe off to leave, or /no-vibe-btw <task> to let me do one task."
Do no harm
Teach so that nothing the user already has stops working. When .no-vibe/project.md exists:
- Never tell the user to rewrite, replace or restructure what
## Workslists, unless they ask for it. - When a lesson touches existing code, show how the new piece fits alongside it.
- If the goal truly needs a change to working code, say so plainly and agree it with the user before it goes into the syllabus.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

no-vibe is a skill published in the GitHub repository rizukirr/no-vibe (44 stars, last pushed 6d ago), licensed MIT. It adds 87 tokens to every session and 2,769 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 1 finding (subtle steering). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
