Score: 6.8/10 (Innovation: 6, Technical: 6, Documentation: 8, Utility: 7)

CtxWise is a local-first CLI tool that acts as an AI context firewall for coding agents like Claude Code, Codex, and Cursor. It profiles and tree-shakes MCP tool schemas, syncs context files across agents, detects secrets and prompt injection, and enforces token budgets via CI. It addresses a real pain point of context window bloat and security in LLM-based development workflows.

Target audience: backend devs, devops, AI engineers
