Agent4s

plugin

Scala code intelligence for AI coding agents. 35 commands — search, jump-to-definition, find references, call-graph, dead code detection, semantic rename, bug-hunt with taint analysis, scaffolding — all without a build server or compilation. Cold index 2.7s, warm 349ms on 18k files. Bug-hunt scans 45 vulnerability patterns (SQL injection, XSS, SSRF, hardcoded secrets, weak crypto, concurrency bugs) with cross-file taint analysis. SemanticDB integration for type-aware mode when compiled artifacts

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

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

Agent4s scores 35 today. Pro keeps the series, so you can see whether that is a project getting better or one on its way down.

The whole series behind any row, back to the first day we measured it
The replacement, named — not just the news that something died

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.
