revdiff: review AI-generated diffs without leaving the terminal

revdiff is a Go TUI diff reviewer (MIT, 459★, v1.3.0) that runs as a terminal overlay inside your AI coding agent session — Claude Code, Codex, or OpenCode. You annotate changed files with plain-text notes; when you close revdiff, the structured annotations pipe straight to stdout and back to the agent. Five versions shipped in five days (May 8–13). Install: `brew install umputun/apps/revdiff`.

sx: a package manager for your AI coding tools

`sx` is an open-source Go CLI that treats AI assets — skills, MCP configs, slash commands, agents, rule files — as versioned, lockfile-managed packages with a multi-client translation layer. Define an asset once, install it into 12+ AI coding clients (Claude Code, Cursor, Copilot, Cline, Codex, Gemini variants, etc.) in each client's native format. Debuted on Hacker News May 16 with 50 points and 28 comments. Install: `brew tap sleuth-io/tap && brew install sx`.

agentmemory: give your AI coding agent a brain that survives the session

Every new Claude Code or Cursor session starts from scratch — same boilerplate context, same corrections. agentmemory is an open-source local MCP server that records what your agent does each session, compresses it, and injects the right context back automatically. It hit #1 on GitHub Trending this week with 6.9K stars. Install is one npx command.
