Use this skill when you need to provide a comprehensive explanation of how a specific feature works, including summaries, deep dives, usage examples, and sequence/workflow diagrams. This skill has references directory which contains additional instructions checklist.md, example-output.md and explanation-template.md that MUST be used for every analysis.

Project Feature Explainer Skill

This skill provides a systematic approach to analyzing and explaining a specific feature within a codebase.

Workflow

1. Identify Entry Points: Locate the main functions, classes, or API endpoints that trigger the feature.
2. Trace Dependencies: Identify the internal modules, services, or external APIs the feature relies on.
3. Analyze Data Flow: Understand how data enters the feature, how it's transformed, and where it's stored or returned.
4. Draft Explanation: Structure the explanation using the mandatory sections below.
5. Verify: Cross-reference the draft with the references/checklist.md to ensure completeness.

Mandatory Output Structure

1. Feature Summary

A high-level overview (1-2 paragraphs) explaining what the feature does and why it exists.

2. Deep Dive (Technical Details)

A detailed breakdown of the internal implementation.

• Key Components: List the main files/classes/functions involved.
• Logic Flow: Step-by-step description of the execution path.
• State Changes: Describe any side effects (e.g., database updates, cache invalidation).

3. Usage & Examples

Code snippets or CLI commands showing how to use the feature.

• Include common parameters and expected outputs.
• Provide a "Happy Path" example.

Guidelines

• Be Concise: Focus on the "how" and "why" without repeating obvious code logic.
• Reference Code: Use specific file paths and symbol names.
• Contextualize: Explain how this feature fits into the broader system architecture.
