Claude Skills by SkillMedev

Converts a prompt a user runs repeatedly into a reusable, paid-quality SKILL.md. Use when someone says "I keep pasting this prompt", "turn this prompt into a skill", "package this workflow", or has a recurring task pattern they want portable across projects and sessions. Do NOT use to author a skill from a capability idea with no existing prompt (use skill-creator) or to restructure an existing SKILL.md (use skill-author).

Do NOT ...

Rewrites a structurally inefficient SQL query into a faster equivalent that returns identical results - correlated subqueries to joins or LATERAL, accidental cross joins to explicit ON predicates, OR-across-columns to UNION, SELECT * to projected columns, and deep OFFSET pagination to keyset. Use when a query is slow because of its shape rather than its indexes - EXPLAIN shows a Cartesian blowup, a per-row subquery, or OFFSET discarding tens of thousands of rows - and the indexes are already ...

Writes quizzes and assessments with a stated Bloom's-level distribution, misconception-based distractors, and an answer key with rationales - plus a summary table of level, type, and points per question.

Use when a freelancer says "I'm fully booked but not earning enough", "how do I raise my rates", "should I grandfather my old clients", "write my rate increase email", "what if they leave when I raise prices", or "when is the right time to charge more". Do NOT use for ne...

Adds retry-with-backoff, Retry-After handling, and client-side throttling so a caller stays under an upstream API's rate limits instead of hammering it. Use when you call a rate-limited or quota-enforced third-party API, see 429 or 503 responses or Retry-After headers, or have a worker fleet that needs to share one upstream's quota.

Do NOT use for building a narrative around quantitative metrics and charts - use dat...

Turns many sources into a decision-ready synthesis - atomic claims clustered into named themes, surfaced tensions between sources, gaps no source answers, and explicit so-what/now-what implications with confidence ratings. Use when someone says "synthesize this research", "what do all these reports agree on", "pull the themes out of these articles", or has a pile of sources and needs conclusions rather than source-by-source summaries.
