This prevents loading unnecessary content while ensuring required functionality is available when needed. The core principle: **Start minimal, expand intelligently, monitor continuously.** ## When To Use Use progressive loading when building skills that: - Cover multiple distinct workflows or domains - Need to manage context window efficiently - Have modules that are mutually exclusive based on context - Require MECW compliance for long-running sessions - Want to optimize for common paths while supporting edge cases ## When NOT To Use - Project doesn't use the leyline infrastructure patterns - Simple scripts without service architecture needs ## Quick Start ### Basic Hub Pattern ```markdown ## Progressive Loading **Context A**: Load `modules/loading-patterns.md` for scenario A **Context B**: Load `modules/selection-strategies.md` for scenario B **Always Available**: Core utilities, exit criteria, integration points ``` **Verification:** Run the command with `--help` flag to verify availability. ### Context-Based Selection ```python from leyline import ModuleSelector, MECWMonitor selector = ModuleSelector(skill_path="my-skill/") modules = selector.select_modules( context={"intent": "git-catchup", "artifacts": ["git", "python"]}, max_tokens=MECWMonitor().get_safe_budget() ) ``` **Verification:** Run the command with `--help` flag to verify availability. ## Hub-and-Spoke Architecture ### Hub Responsibilities 1. **Context Detection**: Identify user intent, artifacts, workflow type 2. **Module Selection**: Choose which modules to load based on context 3. **Budget Management**: Verify MECW compliance before loading 4. **Integration Coordination**: Provide integration points with other skills 5. **Exit Criteria**: Define completion criteria across all paths ### Spoke Characteristics 1. **Single Responsibility**: Each module serves one workflow or domain 2. **Self-Contained**: Modules don't depend on other modules 3. **Context-Tagged**: Clear indicators of when module applies 4. **Token-Budgeted**: Known token cost for selection decisions 5. **Independently Testable**: Can be evaluated in isolation ## Selection Strategies See `modules/selection-strategies.md` for detailed strategies: - **Intent-based**: Load based on detected user goals - **Artifact-based**: Load based on detected files/systems - **Budget-aware**: Load within available token budget - **Progressive**: Load core first, expand as needed - **Mutually-exclusive**: Load one path from multiple options ## Loading Patterns See `modules/loading-patterns.md` for implementation patterns: - **Conditional includes**: Dynamic module references - **Lazy loading**: Load on first use - **Tiered disclosure**: Core → common → edge cases - **Context switching**: Change loaded modules mid-session - **Preemptive unloading**: Remove unused modules under pressure ## Common Use Cases - **Multi-Domain Skills**: `imbue:catchup` loads git/docs/logs modules by context - **Context-Heavy Analysis**: Load relevant modules only, defer deep-dives, unload completed - **Plugin Infrastructure**: Mix-and-match infrastructure modules with version checks ## Best Practices 1. **Design Hub First**: Define all possible contexts and module boundaries 2. **Tag Modules Clearly**: Use YAML frontmatter to indicate context triggers 3. **Measure Token Cost**: Know the cost of each module for selection 4. **Monitor Loading**: Track which modules are actually used 5. **Validate Paths**: Verify all context paths have required modules 6. **Document Triggers**: Make context detection logic transparent ## Module References - **Selection Strategies**: See `modules/selection-strategies.md` for choosing modules - **Loading Patterns**: See `modules/loading-patterns.md` for implementation techniques - **Performance Budgeting**: See `modules/performance-budgeting.md` for token budget model and optimization workflow ## Integration with Other Skills This skill provides foundational patterns referenced by: - `abstract:modular-skills` - Uses progressive loading for skill design - `conserve:context-optimization` - Uses for MECW-compliant loading - `imbue:catchup` - Uses for context-based module selection - Plugin authors building multi-workflow skills Reference in your skill's frontmatter: ```yaml dependencies: [leyline:progressive-loading, leyline:mecw-patterns] progressive_loading: true ``` **Verification:** Run the command with `--help` flag to verify availability. ## Exit Criteria - Hub clearly defines all module loading contexts - Each module is tagged with activation context - Module selection respects MECW constraints - Token costs measured for all modules - Context detection logic documented - Loading paths validated for completeness ## Troubleshooting ### Common Issues **Command not found** Ensure all dependencies are installed and in PATH **Permission errors** Check file permissions and run with appropriate privileges **Unexpected behavior** Enable verbose logging with `--verbose` flag
