SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill determines if changes in a code repository are significant enough to warrant further processing by downstream agents, preventing unnecessary computation and focusing efforts on meaningful updates.

Core Features & Use Cases

  • Change Detection: Identifies staged, unstaged, and untracked files using Git commands.
  • Materiality Classification: Classifies changes as 'none', 'non-material', or 'material' based on predefined file patterns (dependencies, build configs, app surface, etc.).
  • State Management: Updates agent state and logs decisions for traceability.
  • Use Case: Before running a full build or deployment pipeline, this Skill quickly assesses if code modifications affect critical areas like package dependencies or build configurations, deciding whether to proceed or halt execution.

Quick Start

Run the fingerprint skill to detect and classify changes in the repository.

FAQPage Schema
How do I detect and classify repository changes before running a CI/CD pipeline?

To detect and classify repository changes before running a CI/CD pipeline, you can analyze staged, unstaged, and untracked Git files to determine if modifications are material enough to warrant downstream processing.

What is the best way to prevent unnecessary agent execution from non-material Git changes?

Preventing unnecessary agent execution from non-material Git changes requires classifying file modifications against predefined patterns, ensuring only updates to critical areas like dependencies trigger downstream workflows.

How does Git change detection classify material versus non-material file updates?

Git change detection classifies material versus non-material updates by evaluating staged, unstaged, and untracked files against predefined patterns such as build configurations and application surfaces to categorize significance.

Can I use workflow automation to skip builds when only non-material files are modified?

Yes, you can use workflow automation to skip builds by evaluating repository changes, classifying them as none, non-material, or material, and halting agent execution if modifications do not affect critical code areas.

How do I manage agent state and log decisions for cycle control in code analysis?

To manage agent state and log decisions for cycle control in code analysis, the system records materiality classifications and execution decisions, maintaining traceability for automated workflow iterations.

Does this change detection approach work with untracked files in a Git repository?

Yes, this change detection approach works with untracked files in a Git repository by using a Git-first strategy to identify and evaluate all staged, unstaged, and untracked files for materiality classification.
