agent4s
scala-digest/agent4sPlugin
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 are available. Native binaries for macOS, Linux, and Windows. Works as a Claude Code plugin, MCP server (Cursor, Windsurf, Cline), or standalone CLI.
