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.

OpenTelemetry declarative YAML configuration for SDK setup. Use when configuring OpenTelemetry SDK providers (tracer, meter, logger), setting up OTLP exporters, defining sampling strategies, or writing otel config files. Triggers on "otel config", "OpenTelemetry YAML", "declarative configuration", "otelconf", "OTEL_CONFIG_FILE", "file_format", "configure tracing/metrics/logs export", or when the user is setting up telemetry pipelines via config files rather than code.
OpenTelemetry Transformation Language (OTTL) expert for writing and debugging telemetry transformations in the OpenTelemetry Collector. Use when authoring or reviewing `transform`, `filter`, `tail_sampling` processor configs or `routing` connector configs, debugging OTTL syntax or semantics, transforming traces, metrics, logs, or profiles, or converting data-processing requirements into OTTL statements.
Build safe, version-pinned telemetrygen commands for synthetic OTLP traces, metrics, and logs. Use for “send sample traces to this collector,” “load-test an OTLP endpoint,” “generate traffic to verify a processor, OTTL transform, or tail sampling,” and “produce test data for dashboards.” Also use when choosing telemetrygen transport, TLS, attributes, counts, duration, or rate. Not for application SDK instrumentation or production collection that does not use telemetrygen.
OpenTelemetry Weaver registry authoring, codegen, and CI enforcement. Use when adopting Weaver, authoring or reviewing a registry (manifest, attributes, metrics, spans, events), writing Jinja2 templates against the resolved schema, migrating hand-maintained telemetry constants, or wiring `weaver registry check`/`generate`/`diff` into CI.
Configures trace spans, defines custom metrics, sets up log exporters, and optimizes sampling strategies for OpenTelemetry instrumentation. Use when instrumenting applications with traces, metrics, or logs. Triggers on requests for observability, telemetry, tracing, metrics collection, logging integration, or OTel setup.
Verify HitKeep tracking setup and automatic event collection. Use when installation status, missing pageviews or events, WordPress or script installs, automatic outbound clicks, downloads, form submissions, hostname mismatches, blockers, consent, CSP, or the difference between tracker failure and analytics interpretation is in question.
Maintain HitKeep dashboard localization. Use whenever a contributor adds or changes user-visible dashboard text, Transloco keys, locale JSON files, OptimusUI locale behavior, language switching, translated labels, localized layout, date/number/duration formatting, or supported dashboard languages.
Official parent skill for analyzing HitKeep data through HitKeep MCP and official docs. Use for broad traffic, event, ecommerce, Web Vitals, AI visibility, Search Console, opportunity, tracking-health, MCP setup, or analytics-surface questions; use a narrower HitKeep analytics skill when the task clearly matches one.
> Receive and verify Cisco Meraki Dashboard webhook alerts. Use when setting up Meraki webhook handlers, validating the sharedSecret, or handling alert events like motion_alert, settings_changed, sensor_alert, or stopped_reporting.
>- Generate audit reports and compliance trails using Harness audit trail data via MCP v2 tools. Track user actions, resource changes, authentication events, and access patterns across accounts, organizations, and projects. Use when asked to audit activity, generate compliance reports, investigate security incidents, review user actions, check change logs, or produce SOC2/GDPR/HIPAA change log, access audit, security investigation, who changed what, audit events.
Generate DORA metrics and engineering performance reports using Harness SEI via MCP. Track deployment frequency, lead time, change failure rate, and MTTR. Use when user says "DORA metrics", "deployment frequency", "lead time", "engineering metrics", or asks about team performance.
>- Assist with Harness Service Reliability Management (SRM) tasks that the MCP server currently reports from deployment/execution history, and drafting operational runbooks. Use when asked about SLOs, error budgets, burn-rate alerts, on-call handover, runbooks, or incident triage. Do NOT use for DORA metrics (use dora-metrics instead) or chaos experiments (use runbook, service reliability, incident response, on-call shift.
Generate security compliance reports using Harness SCS and STO via MCP. Analyze vulnerabilities, SBOMs, and manage exemptions. Use when user says "security report", "vulnerabilities", "SBOM", "security scan", "compliance check", or asks about application security.
>- Advanced engineering analytics via Harness Software Engineering Insights (SEI) MCP. Configure sprint velocity and estimation accuracy tracking, engineering investment allocation breakdowns, sprint planning with capacity forecasts, and release readiness assessments. Use when asked about sprint analytics, investment allocation, sprint planning, capacity forecasting, or release velocity, sprint analytics, investment allocation, capacity planning, sprint forecast, release readiness, engineering productivity, estimation accuracy, sprint planning, scope creep, code quality trends.
