Vulca

plugin

Vulca adds agent-native visual workflows to Claude Code: visual discovery, brainstorm/spec/plan artifacts, structured prompt composition, semantic layer decomposition, and L1-L5 cultural evaluation. It is designed for reviewable image work instead of one-shot prompting, with local-first defaults and explicit opt-in for provider-backed generation, editing, and evaluation.

Works with: Claude Code (native)
native: this artifact type is that client's own format

Install (Claude Code):

/plugin marketplace add anthropics/claude-plugins-community
/plugin install vulca@claude-community

Security audit

Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.

tashan Pro$6/mo

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.

Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
