verify

verify is a skill for Claude Code from swt-labs/vibe-better-with-claude-code-vbw. It costs 34 tokens per session (392 once invoked), scanned A, original, MIT.

A human review procedure for checking completed work, including its appearance, behavior, and wording, and recording whether each requirement is accepted.

In plain words
What is it for?
Use it to show built requirements to a user, collect a Works or problem verdict, and send rejected work back for changes.
Why use it?
Automated checks may not judge things such as visual quality or whether wording feels right; this process asks a person to make those decisions.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

verify 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 today.

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

"${CLAUDE_PLUGIN_ROOT}/bin/vbw" show requirements 2>&1 || true
"${CLAUDE_PLUGIN_ROOT}/bin/vbw" interview 2>&1 || true

Write to the user's level, explanation depth and involvement (above; "-": plain words).

The requirements to check are the [human, open] or [human, rejected] ones marked built above. None: say what is still being built and stop.

For each one, one at a time: show the user the thing to judge. Run it yourself when you can (the program's actual output, the page's text) and put that, or one concrete thing to try, in the question and the preview of "Works". Something visual: if you can open it (a browser tool), save a screenshot in .vbw/runtime/ and open it for the user (open, xdg-open); otherwise give the exact way to see it. Ask with AskUserQuestion: "Works", "Something's wrong", "Skip for now".

  • Works: vbw req accept <id>.
  • Something's wrong: ask what, in their words, then vbw req reject <id> "<their words>" (VBW fixes it and asks again).
  • Skip for now: vbw req skip <id> (it stays open; /vbw:vibe offers to ship and judge it in the next milestone).

Close with what was accepted and what goes back for fixing; /vbw:vibe continues.

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.
