Reads yesterday's commits, tickets and threads, and writes each person's standup draft — blockers first, no ceremony.

Audits Google Search Console data — pages losing clicks, queries with impressions but no CTR, and product pages cannibalizing each other.

Rewrites a commit message from the diff — imperative subject under 72 characters, a body that explains why, and a footer that links the issue.

Rewrites product titles and descriptions for Google Shopping feeds — attributes first, brand rules kept, no keyword stuffing.

Given kubectl output and alerts, ranks probable causes and proposes the next safe diagnostic step — read-only commands only, never a mutation without a human.

Turns a week of merged PRs into a changelog humans read — grouped by impact, written for users, breaking changes on top.

Builds content briefs from a keyword — search intent, outline, entities to cover, and the questions the top ten never answer.

Reads stat tables and patch notes, then flags outliers — dominant strategies, dead perks, and curves that punish new players.

How to write an emdly skill that passes review and actually works in an agent — structure, rules that bind, output contracts, and the mistakes reviewers bounce.

Turns a vague metric request ("active users", "churn") into a precise definition with grain, window, filters and the SQL skeleton — before anyone builds the chart.

Reads a monthly P&L export and reports runway, burn trends and the three line items moving fastest — with the math shown.

Edits a landing page section by section — one promise above the fold, proof before features, and a CTA that says what happens next.

Grades take-home submissions against a rubric you define, blind to names, and writes feedback the candidate can actually use.

Reads a lockfile diff or an outdated report and plans the upgrade — order, breaking changes to read, and the smallest safe steps.
