What is the 'confidence threshold' mentioned in the documentation?

The skill performs a verification step (like grepping for references) for every finding. It only proceeds with a fix if it is at least 90% certain the code is truly unused and safe to remove.

Can I use this skill as part of a larger automated workflow?

Yes, it is designed to be invocable by quality coordinators like ln-510, typically running after a codebase audit has been completed.

How does the skill ensure my project still builds after changes?

It automatically detects your project's lint and type-check commands. After applying fixes to a file, it runs these checks; if they fail, it reverts changes to that specific file immediately.

Does this skill modify business logic or complex functions?

No. The skill is strictly limited to low-risk, small-effort items like unused imports and dead code. It explicitly skips architectural changes and complex refactoring.

Automatically identifies and removes low-risk technical debt like unused imports and dead code with high confidence and safety checks.

The ln-512-tech-debt-cleaner is a specialized L3 worker skill designed for automated 'garbage collection' within a codebase. By consuming findings from audit reports, it safely eliminates unused imports, dead functions, and commented-out code blocks while ensuring build integrity through local linting and type-checking. It operates with a strict 90% confidence threshold and small-scope limitation, making it an ideal tool for maintaining high code hygiene and reducing cognitive load without risking regressions in core business logic.
