Summary

• Fix Windows .cmd/.bat shim resolution in Lobster plugin when launching through resolveWindowsLobsterSpawn.
• Make cmd-wrapper parsing robust for rooted %dp0% / %~dp0% token variants so valid wrappers resolve to Node entrypoints without shell execution.
• Preserve existing security posture by continuing to reject wrappers that cannot be resolved without shell.

Changes

• extensions/lobster/src/windows-spawn.ts
  • Harden resolveLobsterScriptFromCmdShim to parse %dp0%-style arguments more flexibly and normalize candidate paths reliably.
• extensions/lobster/src/lobster-tool.test.ts
  • Add regression test for rooted %dp0% shim format in Windows path handling.

Validation

• Unit tests updated/covered in extensions/lobster/src/lobster-tool.test.ts.
• This PR is focused and does not include a full suite run.

Greptile Summary

Fixes Windows cmd shim resolution to handle rooted %dp0% token variants. The updated parser now extracts all quoted strings first, then checks for %dp0%/%~dp0% tokens within them, making it robust to different formatting styles. Includes regression test for rooted token format ("%dp0%\\..\\path"). Security posture preserved - continues to reject wrappers that require shell execution.

Confidence Score: 5/5

• Safe to merge - focused fix for Windows cmd shim parsing with test coverage
• The changes are well-scoped, add robustness to path parsing without changing security model, include regression test coverage, and follow existing code patterns
• No files require special attention
