snap

A command that saves the current built web interface as a numbered UI version. It can also report whether the interface is unchanged from the latest saved version.

In plain words
What is it for?
Use it to snapshot a web UI after changes, label the snapshot, and receive its version ID and link.
Why use it?
It removes the need to manually track visual iterations and makes it easier to identify what changed between builds.

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.

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

snap 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 2d 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

Snapshot the current project's built UI into uiver.

  1. Locate the CLI: use uiver if command -v uiver succeeds, otherwise node "$CLAUDE_PLUGIN_ROOT/bin/uiver.js".

  2. If the project's build output (dist/build/out/_site) is missing or stale relative to recent source changes, run the project's build first.

  3. Snapshot:

    • Title: use "$ARGUMENTS" if provided, otherwise write a short 3–6 word label describing the current visual state.
    • Set --prompt to a one-line summary of the most recent UI changes made in this session.
    uiver snap --title "<title>" --prompt "<summary>"
    
  4. Report the version id and URL to the user. If the output says "unchanged", tell the user the UI is identical to the latest stored version.

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.
