 # GEWU local research-agent pack
 
-Version 0.20.12. Adds safe pack update scripts for Windows and POSIX workspaces. Clarifies Antigravity's MCP argument envelope and required project/budget fields, enforces the one-pass diagnostics/context/run sequence, and distinguishes staged sources from registered sources. It keeps prepared proposal JSON byte-for-byte intact, records safe recovery from one missing outer brace in a copied proposal, distinguishes malformed proposals from valid policy holds, makes clear that run state is created through GEWU MCP rather than local run files, avoids headless shell/cache lookups and run-ID reuse across pack changes, groups proposals by semantic learning, guards against placeholder probes, uses server-side canonical digest preparation, stores compact run pins, requires explicit shared scope, checks duplicates, bounds citation reads and checkpoints per-source budgets.

 This pack contains the [agent profile](AGENTS.md), Claude harness pointer ([CLAUDE.md](CLAUDE.md)), shared protocols, four skills and separate pipeline procedures. An existing local host supplies the model and tools. There is no standalone agent engine here.
