概要
The Learner skill transforms Claude from a generic assistant into a project-aware expert by identifying and documenting deep insights discovered during debugging or development. Unlike simple note-taking, it focuses on high-level decision-making heuristics and 'hard-won' lessons that are specific to a codebase but difficult to find via search engines. This ensures that once a complex bug or undocumented architectural pattern is resolved, Claude remembers the underlying logic to prevent regressions and streamline subsequent tasks across the entire development lifecycle.
