v4.3.1 (2026-02-21)

Added

Cursor support

Superpowers now works with Cursor's plugin system. Includes a .cursor-plugin/plugin.json manifest and Cursor-specific installation instructions in the README. The SessionStart hook output now includes an additional_context field alongside the existing hookSpecificOutput.additionalContext for Cursor hook compatibility.

Fixed

Windows: Restored polyglot wrapper for reliable hook execution (#518, #504, #491, #487, #466, #440)

Claude Code's .sh auto-detection on Windows was prepending bash to the hook command, breaking execution. The fix:

• Renamed session-start.sh to session-start (extensionless) so auto-detection doesn't interfere
• Restored run-hook.cmd polyglot wrapper with multi-location bash discovery (standard Git for Windows paths, then PATH fallback)
• Exits silently if no bash is found rather than erroring
• On Unix, the wrapper runs the script directly via exec bash
• Uses POSIX-safe dirname "$0" path resolution (works on dash/sh, not just bash)

This fixes SessionStart failures on Windows with spaces in paths, missing WSL, set -euo pipefail fragility on MSYS, and backslash mangling.
