Best Data & Analytics Skills for Claude Code
Skills for data analysis, SQL, ML pipelines, and experiment statistics. Evaluated on six dimensions with public scorecards — trigger quality through security.
Use for Vercel cost and performance optimization on deployed projects, especially Next.js, Svelte…
Exceptional observability-first pipeline skill: deterministic gates, sub-agent fan-out, verification and sanitizer loops, execFile-only shell-outs with token redaction; only flaws are missing When-Not and bundled README/CONTRIBUTING files.
Parses error messages, traces execution flow through stack traces, correlates log entries to iden…
Excellent debugging skill: five-step workflow backed by a four-phase root-cause methodology, concrete pdb/dlv/git-bisect commands, evidence-required output template; only lacks an explicit When-Not boundary.
Track which of your LinkedIn comments earned author replies. Flags the 6-24h warm-reply window wh…
Tracks the user is own comments and author replies via no-cookie public Apify actors, classifies hot/warm/cool/dormant with a timing matrix, and routes warm threads to reply-handler. Paste fallback without token; all data stays local with only Apify seeing requests; inline injection defenses.
Designs and implements production-grade ML pipeline infrastructure: configures experiment trackin…
Excellent MLOps reference skill with strong progressive disclosure, runnable templates, validation gates, and clean security; only gap is missing When-Not boundary in description.
Performs pandas DataFrame operations for data analysis, manipulation, and transformation. Use whe…
Well-crafted pandas skill: workflow embeds concrete assess and assert-based validation snippets, merge patterns use validate and indicator checks, and before/after examples enforce vectorized idioms; description lacks When-Not.
Use when optimizing PostgreSQL queries, configuring replication, or implementing advanced databas…
Strong PostgreSQL skill featuring an end-to-end slow-query-to-verified-fix example and pre/post index verification discipline; description is thinner than peers and lacks When-Not.
Pull the people who liked or commented on any LinkedIn post and segment them by ICP fit (peer / a…
Fetches public likers/commenters via declared no-cookie Apify actors (no LinkedIn login), parses titles into ICP tiers, outputs roster plus outreach lists locally. Ethical hard rules limit scraping others audiences and DM cadence; data stays local, only Apify sees requests. Minor privacy friction from bulk profiling of third parties.
Use when writing Spark jobs, debugging performance issues, or configuring cluster settings for Ap…
Strong Spark specialist with shuffle-spill validation loop, salting and broadcast patterns, and extensive references; minor flaw is a JDBC example embedding placeholder user/password strings instead of showing secret injection.
Draft a detailed privacy policy covering data types, jurisdiction, GDPR and compliance considerat…
Solid single-file generator with clear steps, input args, legal-review guard flags and a pre-publish checklist; lacks When-Not boundary and any offloaded references.
Creating interactive data visualisations using d3.js. This skill should be used when creating cus…
Solid D3 skill with a clear When-to-use/alternatives section, structured workflow, and troubleshooting guide, but the 820-line SKILL.md underuses its offload files and asset filenames in text (.js) mismatch the shipped .jsx files.
