1.9.1

Install

Drop the attached .zip at your repo root without extracting it — the agent unpacks it as the first step. Then type this shortcut phrase as a chat message to your AI agent (Claude Code, Cursor, Codex, Junie, GitHub Copilot, Windsurf, Air, or Warp):

Install Wavefoundry

That is the only operator-typed command — the agent runs the rest of the install. Prerequisites: Python 3.11+, an MCP-aware agent host. Full walkthrough and host-specific notes in the README.

Upgrade

Already running Wavefoundry? Drop the attached .zip at your repo root without extracting it and type this shortcut phrase to your agent:

Upgrade Wavefoundry

The agent unpacks the zip, advances the framework, runs any required migrations and index rebuilds, and reloads the MCP server. Review the version notes below for anything that re-indexes or changes behavior on this upgrade.

[1.9.1] - 2026-06-26

Fixed

• Native-Windows MCP server reliability (broken pipe on startup). The tool venv is now activated in-process (site.addsitedir) instead of re-execing into the venv interpreter. The re-exec used a subprocess child on Windows (no in-place exec there), which became a second process holding the same stdout pipe the MCP host owns — causing an intermittent broken pipe when the tool list arrives and orphaned processes across reconnects. In-process activation keeps a single host-spawned process on every OS while preserving the byte-identical command: "python". If the venv was built for a different Python (major, minor) than the running interpreter (e.g. after a system Python upgrade), normal entries fail loud with a clear "run wf setup to rebuild" message, while wf setup bypasses activation and recreates the stale tool venv. Wave 1p7pk / 1p802.
