WinBrain

Profile and explore a dataset to understand its shape, quality, and patterns. Use when encountering a new table or file, checking null rates and column distributions, spotting data quality issues like duplicates or suspicious values, or deciding which dimensions and metrics to analyze.

QA an analysis before sharing -- methodology, accuracy, and bias checks. Use when reviewing an analysis before a stakeholder presentation, spot-checking calculations and aggregation logic, verifying a SQL query's results look right, or assessing whether conclusions are actually supported by the data.

Write optimized SQL for your dialect with best practices. Use when translating a natural-language data need into SQL, building a multi-CTE query with joins and aggregations, optimizing a query against a large partitioned table, or getting dialect-specific syntax for Snowflake, BigQuery, Postgres, etc.

Apply statistical methods including descriptive stats, trend analysis, outlier detection, and hypothesis testing. Use when analyzing distributions, testing for significance, detecting anomalies, computing correlations, or interpreting statistical results.

Generate or improve a company-specific data analysis skill by extracting tribal knowledge from analysts. BOOTSTRAP MODE - Triggers: "Create a data context skill", "Set up data analysis for our warehouse", "Help me create a skill for our database", "Generate a data skill for [company]" → Discovers schemas, asks key questions, generates initial skill with reference files ITERATION MODE - Triggers: "Add context about [domain]", "The skill needs more info about [topic]", "Update the data skill with [metrics/tables/terminology]", "Improve the [domain] reference" → Loads existing skill, asks targeted questions, appends/updates reference files Use when data analysts want Claude to understand their company's specific data warehouse, terminology, metrics definitions, and common query patterns.

Build an interactive HTML dashboard with charts, filters, and tables. Use when creating an executive overview with KPI cards, turning query results into a shareable self-contained report, building a team monitoring snapshot, or needing multiple charts with filters in one browser-openable file.

Write correct, performant SQL across all major data warehouse dialects (Snowflake, BigQuery, Databricks, PostgreSQL, etc.). Use when writing queries, optimizing slow SQL, translating between dialects, or building complex analytical queries with CTEs, window functions, or aggregations.

Produce a self-contained HTML artifact instead of a markdown document when the request is for content that benefits from spatial layout, color, real diagrams, interactivity, or a round-trip editor. Use this skill aggressively whenever the user asks for a "doc," "writeup," "plan," "spec," "report," "explainer," "summary," "comparison," "review," "PR description," "mockup," "diagram," "flowchart," "deck," "slides," "status update," "post-mortem," "incident report," "playground," or a one-off "editor" or "tool" for triaging/reordering/tuning anything — even if they don't explicitly say "HTML" or "artifact." Also trigger when the user asks Claude to "explain," "summarize," "compare," "explore options for," "brainstorm directions for," or "walk through" a non-trivial topic. Stay in markdown only for short conversational replies, code-only outputs, terminal-style command answers, and content that's genuinely just a few sentences.

Install and use the Everything Claude Code (ECC) agent harness assets in this project. Use for ECC hooks, skills, plugins, commands, and agents, and for refreshing the vendored ECC snapshot.

Explore, inspect, explain, and chat about the WinBrain OceanBase/MySQL database using its metadata snapshot. Use for table or column discovery, schema documentation, read-only SQL drafting, join-key investigation, data-quality check planning, and questions about WinBrain database structure. Ground every answer in the snapshot, label inference, and never execute or propose database writes.

Build targeted account or contact lists using Common Room's Prospector. Triggers on 'find companies that match [criteria]', 'build a prospect list', 'find contacts at [type of company]', 'show me companies hiring [role]', or any list-building request.
