What is live-canvas-marketplace?

A marketplace package that provides the Live Canvas browser overlay and its Claude Code connection. Live Canvas lets someone click on a browser preview to add feedback, which is sent to a Claude Code session.

Use it for reviewing websites or interfaces in a browser and sending click-based feedback into Claude Code.

It creates a direct path from visual review in the browser to the coding assistant. This avoids manually describing or transferring each annotation.

Security

Grade A, and why

live-canvas-marketplace 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 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.
