Code Remix Weekly | Better grep, better agents Bryan Friedman from Moderne is showing why grep and IDE features fall short when you're working across large, decentralized codebases. Traditional tools can'...

Grep doesn't cut it across 500 repos. Bryan Friedman shows how semantic code search actually works.

Local Moderne MCP: Deterministic Tools for Coding Agents The Moderne CLI runs a local MCP server that gives coding agents Trigrep search, LST-backed semantic analysis, and deterministic recipe execution, all without leaving the repo

Coding agents default to grep and file reads.

On a large codebase, that eats tokens fast and still misses things.

Moderne gives the agent smarter search and pre-built, deterministic code changes instead.

How it works:

CVE-2026-22732: Detecting Spring Security Header Suppression How OpenRewrite's taint analysis finds every way a Spring controller commits a response too early, including the edge cases pattern matching misses

Your Spring Security advisory tells you what's broken. It doesn't tell you where. 🔍

Semgrep catches the demo-shaped case. It misses the helper method, the field stash, the wrapper subclass.

This blog explores why taint analysis finds every variant & why pattern matching can't.
