Names the domain (learning rules) and some actions (capture correction/lesson with category, mistake, correction), but doesn't comprehensively list all capabilities or concrete actions beyond the basic capture function.

Clearly answers both what ('Capture a correction or lesson as a persistent learning rule with category, mistake, and correction') and when ('Use after mistakes or when the user says "remember this"') with explicit triggers.

Includes some natural terms like 'remember this' and 'mistakes', but missing common variations users might say like 'don't forget', 'note this', 'learn from this', 'save this rule', or 'I corrected you'.

Clear niche focused on capturing corrections and learning rules with distinct triggers ('remember this', 'after mistakes'); unlikely to conflict with general note-taking or documentation skills due to the specific correction/lesson framing.

The skill is lean and efficient, with no unnecessary explanations. Every section serves a purpose and assumes Claude understands basic concepts like memory persistence and rule formatting.

Provides concrete format templates, a clear workflow with numbered steps, specific trigger phrases, and a practical example showing exact input/output. The guardrails give specific actionable guidance (e.g., 'Always use snake_case for database columns' vs 'Write good code').

Clear 4-step workflow with explicit approval checkpoint before persisting. The guardrail 'Always wait for user approval before persisting' ensures validation before destructive/permanent changes.

For a skill under 50 lines with no need for external references, the content is well-organized with clear sections (Trigger, Workflow, Format, Categories, Example, Guardrails, Output). The category table provides quick reference without bloating the main content.
