Data Analysis Claude Skills
2 409 data analysis skills from 443 authors. They crunch numbers, pivot tables and turn both into something readable. Half of them fit into 1 952 tokens or less — that is what one costs your context window when the agent loads it. 549 ship runnable scripts rather than instructions alone. 31 of them cannot work without an MCP server, most often rube. We also found 386 copies of these same skills sitting in other people's repositories — counted once here, not 386 times.

Read-only on tracker state; consumes campaign artefacts.
| Read-only maintainer dashboard for the open general-issue backlog of <issue-tracker>. Surfaces a health rating, prioritised recommendations, age and staleness breakdowns, area pressure ranking, and a triage-funnel summary. Output is HTML by default; markdown fallback available.
| Read-only maintainer dashboard for the open-PR backlog of <upstream>. Surfaces a health rating, prioritised action recommendations, weekly closure velocity trends, area pressure ranking, and a triage-funnel breakdown — with the underlying area-grouped tables as a collapsible details section.

Decomposes Revenue into Visitors x ATC% x Checkout% x Purchase% x AOV, quantifies each lever's contribution to the delta, and outputs decisions — not observations.
Optimize CV and resume content for recruiter readability and parser-safe ATS handling without making unsupported claims about exact vendor scoring.

| Generate intelligence briefings for the planning dashboard. Use this skill whenever a request file appears in `.planning/console/inbox/pending/` whose `type` field starts with `intelligence.` (refresh_briefing, triage_finding, snapshot_diff, investigate_section, dismiss_finding). The skill reads the per-project KB at `.gsd/intelligence/intelligence.db`, synthesizes a briefing with a causal hypothesis + acknowledged uncertainty + confidence label and ranked moves, then writes the result back to the KB. Always trigger this skill for these request types — do not generate briefings manually.
OpenStack monitoring operations skill for deploying, configuring, and operating the cloud health monitoring stack.

Push notifications for React Native CometChat — APNs + FCM setup, dashboard provider configuration, client registration, token lifecycle, foreground display, background wake, tap-to-deep-link, and the Expo Go / APNs-environment traps that silently break production.
Feature catalog for CometChat Angular UI Kit v5 (@cometchat/chat-uikit-angular@5) — how to enable/configure calls, reactions, mentions, AI (smart replies / conversation starter / summary), polls, stickers, collaborative doc/whiteboard, message translation, link preview. Five-bucket taxonomy: auto-enabled / component-prop / dashboard-extension / AI-with-OpenAI-key / package-install (calls). Verified @Input names against the v5 .d.ts.

Covers what's auto-enabled, what needs UIKitSettings flags, what's enabled by `cometchat apply-feature <id>`, and what needs manual dashboard configuration (third-party API keys).
Push notifications for React Native CometChat — APNs + FCM setup, dashboard provider configuration, client registration, token lifecycle, foreground display, background wake, tap-to-deep-link, and the Expo Go / APNs-environment traps that silently break production.
Build institutional-grade comparable company analyses with operating metrics, valuation multiples, and statistical benchmarking in Excel/spreadsheet format.
Audit a spreadsheet for formula accuracy, errors, and common mistakes. Scopes to a selected range, a single sheet, or the entire model, including financial-model integrity checks like BS balance, cash tie-out, and logic sanity. Triggers on "audit this sheet", "check my formulas", "find formula errors", "QA this spreadsheet", "sanity check this", "debug model", "model check", "model won't balance", "something's off in my model", and "model review".
Clean up messy spreadsheet data — trim whitespace, fix inconsistent casing, convert numbers-stored-as-text, standardize dates, remove duplicates, and flag mixed-type columns. Use when data is messy, inconsistent, or needs prep before analysis. Triggers on "clean this data", "clean up this sheet", "normalize this data", "fix formatting", "dedupe", "standardize this column", and "this data is messy".
When the user wants to plan, design, or implement an A/B test or experiment. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," or "hypothesis." For tracking implementation, see analytics-tracking.
When the user wants to set up, improve, or audit analytics tracking and measurement. Also use when the user mentions "set up tracking," "GA4," "Google Analytics," "conversion tracking," "event tracking," "UTM parameters," "tag manager," "GTM," "analytics implementation," or "tracking plan." For A/B test measurement, see ab-test-setup.
Formula WorkPaper runtime and MCP server for AI agents and Node.js services. Use when an agent needs spreadsheet-style formulas, cell edits, recalculation, readback verification, or persisted WorkPaper JSON without driving Excel UI.
The branded entry point to ServiceGraph — use whenever the user explicitly names **ServiceGraph** — "use ServiceGraph to…", "what datasets does ServiceGraph have", "search ServiceGraph for…", "look this up in ServiceGraph", "pull contacts from ServiceGraph for these domains", "how many credits do I have on ServiceGraph". ServiceGraph is a multi-dataset platform of metrics-enriched business data for founders — where to launch, who to email, who to hire. This skill explains how to drive the API (api.servicegraph.co / mcp.servicegraph.co) against ANY dataset — discover what datasets exist, discover a dataset's schema and filters, search free brief rows, and unlock contact + metric detail with credits. Dataset-agnostic by design — it discovers everything through the API and never assumes which datasets or fields exist. When the user describes an intent WITHOUT naming ServiceGraph (e.g. "find a PR agency in NY"), defer to the matching specific skill (find-pr-agency, find-marketing-agency, find-law-firm, …); this skill is for explicit ServiceGraph requests and for datasets no specific skill covers yet. Skip non-US firms, consumer/personal services, and individual freelancers.
