fix(loop): replace non-existent --prompt-file with -p flag
The build_claude_command() function was incorrectly using --prompt-file which doesn't exist in Claude Code CLI. This fix: - Replaces --prompt-file with -p flag plus prompt content - Reads prompt content via $(cat "$prompt_file") before execution - Adds error handling for missing prompt files - Maintains shell injection safety through array-based command building - Updates comments to reflect the correct approach Adds 6 TDD tests verifying the fix: - Uses -p flag instead of --prompt-file - Reads prompt file content correctly - Handles missing prompt file - Includes all modern CLI flags - Handles multiline prompt content - Prevents shell injection Test count: 145 -> 151 (all passing)

## Recent Improvements
|
||||
|
||||
### Prompt File Fix (v0.9.2)
|
||||
- Fixed critical bug: replaced non-existent `--prompt-file` CLI flag with `-p` flag
|
||||
- Modern CLI mode now correctly passes prompt content via `CLAUDE_CMD_ARGS+=("-p" "$prompt_content")`
|
||||
- Added error handling for missing prompt files in `build_claude_command()`
|
||||
- Added 6 new TDD tests for `build_claude_command` function
|
||||
- Maintains shell injection safety through array-based command building
|
||||
- Test count: 151 (up from 145)
|
||||
|
||||
### CLI Parsing Tests (v0.9.1)
|
||||
- Added 27 comprehensive CLI argument parsing tests
|
||||
- Covers all 12 CLI flags with both long and short forms

**Modern CLI Flags**
|
||||
- `--output-format json|text` - Control Claude output format
|
||||
- `--allowed-tools` - Restrict tool permissions
|
||||
- `--prompt-file` - Use file instead of stdin piping
|
||||
- `-p` with content - Pass prompt content (reads from file via command substitution)
|

- Version checking with `check_claude_version()`
