What is the difference between structural and semantic checks?

Structural checks are programmatic (finding missing files or dead paths), while semantic checks involve the AI analyzing the content to find outdated logic, superseded decisions, or contradictory rules.

What is context drift in AI coding?

Context drift occurs when project documentation, architectural notes, or conventions no longer match the actual state of the codebase, which can lead to AI hallucinations or errors.

How does ctx-drift fix structural issues?

It uses the 'ctx drift --fix' command to automatically remove or update references to files that have been moved, renamed, or deleted within the context files.

When should I run the ctx-drift skill?

It is best used after refactoring code, at the start of a session to verify health, or whenever you notice the AI is referencing files that no longer exist.

Can this skill update my local permissions automatically?

No. For security reasons, it only reports permission drift in settings.local.json and provides the user with a report to make manual updates.

学習とドキュメンテーション

Identifies and repairs inconsistencies between project documentation and actual code to maintain AI context accuracy.

The Context Drift Detector is an essential maintenance tool for the ctx system, ensuring that AI coding assistants always work with accurate, up-to-date project information. It performs dual-layer analysis: structural checks to find dead file paths or missing references, and semantic analysis to identify outdated conventions or superseded architectural decisions. By proactively resolving 'context rot,' this skill prevents the AI from making hallucinations based on stale data, streamlines session rehydration, and ensures that your project's ARCHITECTURE.md and CONVENTIONS.md files remain a source of truth.
