vibe-check

vibe-check is a command for coding agents from OneWave-AI/open-agent-stack. It costs 20 tokens per session (644 once invoked), scanned A, original, MIT.

A review command for checking whether an AI-built app is ready to ship. It examines whether the app is real, safe, maintainable, visually credible, usable, and ready for production.

In plain words
What is it for?
Use it to audit an app and receive a prioritized list of issues with supporting file paths and line references. It reports findings but does not fix them.
Why use it?
It finds fake data, exposed secrets, missing security checks, duplicated code, and other problems before they reach users.

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

vibe-check 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 4d 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.

What it actually says

Vibe Check

Audit the app in the current directory and report where it really stands. Do not fix anything yet -- the output is a diagnosis and a plan the user chooses from.

Assess these six axes. For each, give a one-line verdict and the specific evidence (file paths, line references) behind it.

  1. Real or demo -- Is the UI telling the truth? Hunt hardcoded arrays feeding lists and charts, useState standing in for a session, form handlers with no network call, and routes returning fixtures. Anything on the money path that is fake is the highest-severity finding in this audit.
  2. Safe to be public -- Secrets in source or committed .env files, keys exposed to the browser (NEXT_PUBLIC_ and anything used client-side), mutating API routes with no auth check, and unvalidated user input hitting the database.
  3. Built to survive change -- Duplicated primitives (two button components, two fetch helpers), raw hex instead of design tokens, dead code, and dependencies nothing imports. Note the two files most likely to break when the next feature lands.
  4. Looks human-made -- The AI tells: centered gradient hero, symmetric three-card grid, emoji used as icons, uniform radius and shadow on everything, "Unlock/Supercharge/Seamlessly" copy, identical section rhythm throughout.
  5. Motion holds together -- Count the distinct animation durations and easings in the codebase; more than three or four of either means there is no motion system. Then check for the specific failures: layout properties being animated (width, height, top, left) instead of transform, transition: all, missing :focus-visible styles, missing :active press states, no prefers-reduced-motion handling anywhere, markers: true left in a ScrollTrigger, and GSAP created outside useGSAP or a useEffect with no cleanup.
  6. Deployable today -- Does npm run build pass (run it), does typecheck pass, is every process.env variable the code reads actually documented and set, and do error, empty, and loading states exist on the main screens.

Then output:

  • Blockers -- ship-stopping, in severity order, each with the skill that fixes it (make-it-real, ship-it, unstick, add-feature, polish-pass, motion-system, gsap-web, scroll-story, micro-interactions, motion-perf, handoff).
  • Worth fixing -- real problems that are not blockers.
  • Fine as-is -- so the user knows what not to spend time on. Say this explicitly; an audit that flags everything is useless.

Be specific and be honest. "Consider improving error handling" helps nobody -- "app/dashboard/page.tsx:34 renders a hardcoded revenue array while the UI implies live data" does.

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.

vibe-check is a command published in the GitHub repository OneWave-AI/open-agent-stack (2 stars, last pushed 24d ago), licensed MIT. It adds 20 tokens to every session and 644 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
