Summary

  • unwrap PowerShell and Pwsh command launchers for readable tool rows
  • unwrap cmd /c launchers while preserving POSIX shell behavior
  • retain incomplete commands and quoted flag-like arguments unchanged

Verification

  • npm run check:web (193 files, 2219 tests)
  • TypeScript typecheck included in check:web

Summary by CodeRabbit

  • Bug Fixes
    • Improved shell command detection and unwrapping for POSIX shells, PowerShell, and Command Prompt.
    • Added support for PowerShell’s short -c and -f options, along with common executable names.
    • Correctly handles trailing arguments after wrapped commands.
    • Prevents PowerShell script arguments from being mistaken for wrapper options after -File or -f.
    • Preserves ordinary, incomplete, and unclosed-quote commands without altering them.

📝 Walkthrough

Walkthrough

Shell command unwrapping now preserves command boundaries and supports POSIX, PowerShell, and cmd.exe wrappers. Tokenization provides positional and quote metadata. PowerShell scanning stops at an unquoted -File option boundary.

Changes

Shell command unwrapping

Layer / File(s) Summary
Token metadata and wrapper detection
src/lib/harness/shellIntent.ts
tokenize now returns token values, offsets, and quote metadata. unwrapShellCommand uses this data to process POSIX, PowerShell, and cmd.exe wrappers. inferShellIntent maps token objects to argument values.
Wrapper behavior validation
src/lib/harness/shellIntent.test.ts
Tests cover trailing POSIX arguments, PowerShell and cmd.exe command wrappers, the PowerShell -File boundary, ordinary commands, and incomplete commands.

74-87: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The PowerShell wrapper patterns recognize only the full -Command and -File spellings. If the supported pwsh abbreviations -c and -f are used, command rows either remain wrapped or can scan past a file-script boundary and unwrap a later -Command argument. Recognize the supported aliases when locating command flags and file boundaries.

Thanks @notsapinho

Could you tighten the quote handling before we merge?
trimMatchingOuterQuotes() currently removes the first and last quote without confirming they enclose the whole command.

For example:
pwsh -Command 'Get-Date' '-Format' 'yyyy-MM-dd'

becomes:
Get-Date' '-Format' 'yyyy-MM-dd

Also, quoted options such as pwsh "-Command" "Get-Content package.json" are not unwrapped because quoted tokens are skipped, even though the shell passes "-Command" as the normal -Command argument.

Could you preserve separately quoted arguments, recognize quoted wrapper options while still stopping at -File/-f, and add tests for both cases?

Everything else looks good and CI is green.
