A personal AI memory file (MEMORY.md, CLAUDE.md, custom instructions) is only as good as it is current — over time it bloats with stale rules, contradicts itself, and drifts from who you actually are now. This tends it: reviews what's there, prunes the dead weight, sharpens the vague, adds the new patterns worth keeping, and sets a light maintenance habit — so your AI keeps understanding the real you. It also re-checks the privacy line on what should never be in there.
Ask for these if not provided:
Prune (remove): stale · redundant · resolved]. Sharpen (rewrite vaguer → clearer): "vague]" → "clear, actionable]"]. Contradictions to resolve: conflicting instructions → the one to keep]. Add (from recent patterns): new preferences/rules/lessons]. Privacy check: confirm no credentials/financial/health/others' data → remove if found]. Maintenance habit: a quick periodic review + add-a-line-as-you-go].

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted. The headline lift of +13 percentage points is the difference between those two pass rates over the 23 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
