Does this skill require manual code annotations?

No, while it supports optional annotations like '// Implements: PRD-1', it primarily uses heuristics such as test file analysis and function naming to detect alignment.

Can it identify extra work that wasn't requested?

Yes, it specifically flags 'Extra' or 'Scope Creep' items when it detects new functionality that does not map back to any defined requirement in your PRD or SDD.

How does it log drift decisions?

The skill automatically appends findings and user decisions to a dedicated 'Drift Log' section in your project's specification README for permanent traceability.

What is drift detection in software development?

Drift detection is the process of identifying when the actual code implementation deviates from the original design documents, requirements, or project plans.

Productivity & Workflow

Monitors and identifies discrepancies between project specifications and code implementation to ensure architectural alignment.

The Drift Detection skill acts as a specification alignment specialist for Claude Code, continuously monitoring implementation phases to identify scope creep, missing features, and contradictions. By analyzing PRDs, design documents, and project plans against actual code and tests, it provides developers with actionable insights and logs alignment decisions directly to project documentation for full traceability. This ensures that development remains focused on defined goals while providing a conscious process for acknowledging and documenting necessary deviations.
