Workspace Paths Configuration Feature

Summary

This PR introduces support for multiple workspace paths configuration in cecli, allowing users to specify multiple directories to watch and manage within a single session.

Changes

1. Core Functionality

• args.py: Added --workspace-paths argument to accept multiple workspace directory paths
• args_formatter.py: Updated formatters to properly document the new configuration option in .env, YAML, and Markdown formats
• main.py: Integrated workspace paths resolution into the main initialization flow

2. Integration with Skills System

• tools/load_skill.py and tools/remove_skill.py: Ensure proper skill loading/removal is aware of workspace context
• helpers/skills.py: Updated SkillsManager to work with multiple workspace paths

Usage Examples

CLI Usage

# Single workspace path (default behavior)
cecli --workspace-paths src/myapp

# Multiple workspace paths (NEW)
cecli --workspace-paths frontend/backend --workspace-paths shared/utils

# With other flags
cecli --workspace-paths src --model gpt-4 --edit-format architect

YAML Configuration (.cecli.conf.yml)

workspace-paths:
  - frontend/src
  - backend/app
  - shared/utils

model: gpt-4
edit-format: agent

Environment Variable (.env)

# Multiple workspace paths (space-separated)
WORKSPACE_PATHS=frontend/src backend/app shared/utils

# Or single path (legacy behavior still works)
WORKSPACE_PATHS=src/myapp

Benefits

1. Monorepo Support: Easily work across multiple directories in monorepos without manually adding files each time
2. Shared Code: Include shared libraries or utilities alongside application code seamlessly
3. Flexible Organization: Support for various project structures and organizational needs

Backward Compatibility

This change is fully backward compatible:

• Single workspace path still works as before (default behavior unchanged)
• Existing configurations continue to work without modification

Testing Notes

The feature has been tested with:

• Single path specification (legacy behavior)
• Multiple paths via repeated CLI flags
• Multiple paths via YAML configuration
• Environment variable configuration (space-separated paths)
