Is Rex safe and trustworthy?

tashan scores Rex on public evidence — tashan score 21.0/100, it is currently abandoned, note: a single primary maintainer (bus-factor risk). Audit scope: OSV advisories, install-time scripts, build provenance and declared permission surface. We do not review source code or execute the capability.

How do I install Rex?

Configure it from its source repository — it is a remote / registry server.

Rex

plugin

Rex provides sub-second Python symbol search across all installed .venv packages. Three tools — rexfind, rexshow, rexmembers — let Claude look up function signatures, docstrings, class members, and file locations instantly, without web search or grepping through source files. Results are grounded in the actually installed version — no outdated docs, no hallucinated parameters. Auto-indexes on first use and re-indexes incrementally when packages change. Read-only by design.

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 rex@claude-community

You are reading this because you came looking. tashan Pro gives tashan doctor the history behind it, so a run over your own config says which of YOURS moved.

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.
