Added Draft System Services section with all three services - Documented why NO CACHING is used for draft services - Explained architecture integration (global lock, background monitor) - Documented hybrid linear+snake draft format Tasks Documentation (tasks/CLAUDE.md): - Added Draft Monitor task documentation - Detailed self-terminating behavior and resource efficiency - Explained global lock integration with commands - Documented auto-draft process and channel requirements Commands Documentation (commands/draft/CLAUDE.md): - Complete reference for /draft command - Global pick lock implementation details - Pick validation flow (7-step process) - FA player autocomplete pattern - Cap space validation algorithm - Race condition prevention strategy - Troubleshooting guide and common issues - Integration with background task - Future commands roadmap All documentation follows established patterns from existing CLAUDE.md files with comprehensive examples and code snippets. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- commands/draft/CLAUDE.md | 263 +++++++++++++++++++++++++++++++++++++++ services/CLAUDE.md | 55 ++++++++ tasks/CLAUDE.md | 85 +++++++++++++ 3 files changed, 403 insertions(+) create mode 100644 commands/draft/CLAUDE.md diff --git a/commands/draft/CLAUDE.md b/commands/draft/CLAUDE.md new file mode 100644 index 0000000..5a51099 --- /dev/null +++ b/commands/draft/CLAUDE.md @@ -0,0 +1,263 @@ + + +# Draft Commands + +This directory contains Discord slash commands for draft system operations. + +## Files + +### `picks.py` +- **Command**: `/draft` +- **Description**: Make a draft pick with FA player autocomplete +- **Parameters**: + -
