alirezarezvani/…e-skills

Audit datasets for completeness, consistency, accuracy, and validity. Profile data distributions, detect anomalies and outliers, surface structural issues, and produce an actionable remediation plan. Use when the user asks to check data quality, profile a dataset, hunt outliers or missing values, or validate data before analysis or model training.

SKILL.md

You are an expert data quality engineer. Your goal is to systematically assess dataset health, surface hidden issues that corrupt downstream analysis, and prescribe prioritized fixes. You move fast, think in impact, and never let "good enough" data quietly poison a model or dashboard.

Entry Points

Mode 1 — Full Audit (New Dataset)

Use when you have a dataset you've never assessed before.

  1. Profile — Run data_profiler.py to get shape, types, completeness, and distributions
  2. Missing Values — Run missing_value_analyzer.py to classify missingness patterns (MCAR/MAR/MNAR)
  3. Outliers — Run outlier_detector.py to flag anomalies using IQR and Z-score methods
  4. Cross-column checks — Inspect referential integrity, duplicate rows, and logical constraints
  5. Score & Report — Assign a Data Quality Score (DQS) and produce the remediation plan

Mode 2 — Targeted Scan (Specific Concern)

Use when a specific column, metric, or pipeline stage is suspected.

Use when browsing or choosing among engineering-team role skills — load only the one specialist SKILL.md you need, never bulk-load the bundle.测试与安全2397finance-skillsalirezarezvani/…e-skillsRouter/index for the finance skills bundled in this plugin: financial-analyst (ratio analysis, DCF valuation, budget variance, rolling forecasts), saas-metrics-coach (ARR/MRR, churn, CAC/LTV, NRR, quick ratio) and month-end-close (close calendar, reconciliations, flux review). Use when a finance request doesn't obviously match one skill and you need to pick the right one (e.g., 'analyze these financials', 'how healthy are my SaaS metrics').数据与研究2320marketing-skillsalirezarezvani/…e-skillsDirectory and router for the marketing skills library. Use when you need to find the right marketing skill for a task, see what marketing capabilities exist, or get oriented in this plugin. 44 specialist skills across 8 pods (content, SEO + AEO, CRO, channels, growth, intelligence, sales enablement, ops), 59 stdlib Python tools. Routes to one skill — it does not execute marketing work itself.营销与写作2274business-growth-skillsalirezarezvani/…e-skillsRouter/index for the 4 business & growth skills bundled in this plugin: customer-success-manager (health scoring, churn risk, expansion), sales-engineer (RFP analysis, competitive matrices, PoC planning), revenue-operations (pipeline, forecast accuracy, GTM efficiency), and contract-and-proposal-writer. Use when a growth/revenue request doesn't obviously match one skill and you need to pick the right one (e.g., 'which accounts are at risk', 'should we bid on this RFP').营销与写作2198engineering-advanced-skillsalirezarezvani/…e-skillsIndex of 37 advanced engineering agent skills for Claude Code, Codex, Gemini CLI, Cursor, OpenClaw. Use when browsing or choosing among the POWERFUL-tier engineering skills: agent design, RAG, MCP servers, CI/CD, database design, observability, security auditing, changelog/release automation, reliability (SLO/chaos/flags/operators), platform ops.设计与多媒体2024product-skillsalirezarezvani/…e-skillsUse when coordinating product work across the 12 bundled product sub-skills (RICE, OKRs, UX research, design tokens, competitive teardown, analytics, experiments, discovery, roadmaps, spec-to-repo, landing pages, SaaS scaffolding) or the 4 standalone product-team plugins (user stories, Apple HIG, code-to-PRD, research summarizer). Triggers on 'help me prioritize', 'plan a product experiment', 'we ship features nobody uses', 'run the discovery loop', 'is our OST sound'. Forks context to route to one sub-skill via a deterministic signal router and returns a digest; can also drive a continuous-discovery loop (Torres cadence tracker + OST linter as machine gates) or a full goal→plan→execute→verify→close run through the repo-wide agent-harness. Distinct from project-management (how to deliver vs what to build), marketing/landing (from-scratch pages), and engineering/agent-harness (the generic loop engine this orchestrator plugs into).数据与研究2004
