Answer a data question, from a quick lookup to a full analysis to a formal report.
Usage
/analyze <natural language question>
Workflow
1. Understand the Question
Parse the user's question and determine:
- Complexity level:
- Quick answer: Single metric, simple filter, factual lookup (e.g., "How many users signed up last week?")
- Full analysis: Multi-dimensional exploration, trend analysis, comparison (e.g., "What's driving the drop in conversion rate?")
- Formal report: Comprehensive investigation with methodology, caveats, and recommendations (e.g., "Prepare a quarterly business review of our subscription metrics")
- Data requirements: Which tables, metrics, dimensions, and time ranges are needed
- Output format: Number, table, chart, narrative, or combination
2. Gather Data
If a data warehouse MCP server is connected:
- Explore the schema to find relevant tables and columns
- Write SQL query(ies) to extract the needed data
- Execute the query and retrieve results
- If the query fails, debug and retry (check column names, table references, syntax for the specific dialect)
- If results look unexpected, run sanity checks before proceeding
If no data warehouse is connected:
- Ask the user to provide data in one of these ways:
- Paste query results directly
- Upload a CSV or Excel file
- Describe the schema so you can write queries for them to run
- If writing queries for manual execution, use the
sql-queriesskill for dialect-specific best practices - Once data is provided, proceed with analysis
3. Analyze
- Calculate relevant metrics, aggregations, and comparisons
- Identify patterns, trends, outliers, and anomalies
- Compare across dimensions (time periods, segments, categories)
- For complex analyses, break the problem into sub-questions and address each
4. Validate Before Presenting
Before sharing results, run through validation checks:
- Row count sanity: Does the number of records make sense?
- Null check: Are there unexpected nulls that could skew results?
- Magnitude check: Are the numbers in a reasonable range?
- Trend continuity: Do time series have unexpected gaps?
- Aggregation logic: Do subtotals sum to totals correctly?
If any check raises concerns, investigate and note caveats.
5. Present Findings
For quick answers:
- State the answer directly with relevant context
- Include the query used (collapsed or in a code block) for reproducibility
For full analyses:
- Lead with the key finding or insight
- Support with data tables and/or visualizations
- Note methodology and any caveats
- Suggest follow-up questions
For formal reports:
- Executive summary with key takeaways
- Methodology section explaining approach and data sources
- Detailed findings with supporting evidence
- Caveats, limitations, and data quality notes
- Recommendations and suggested next steps
6. Visualize Where Helpful
When a chart would communicate results more effectively than a table:
- Use the
data-visualizationskill to select the right chart type - Generate a Python visualization or build it into an HTML dashboard
- Follow visualization best practices for clarity and accuracy
Examples
Quick answer:
/analyze How many new users signed up in December?
Full analysis:
/analyze What's causing the increase in support ticket volume over the past 3 months? Break down by category and priority.
Formal report:
/analyze Prepare a data quality assessment of our customer table -- completeness, consistency, and any issues we should address.
Tips
- Be specific about time ranges, segments, or metrics when possible
- If you know the table names, mention them to speed up the process
- For complex questions, Claude may break them into multiple queries
- Results are always validated before presentation -- if something looks off, Claude will flag it

Reads a forwarded customer email or ticket, pulls order/refund status from PayPal and account history from HubSpot, drafts a tone-matched reply in the owner's writing voice, and can issue a PayPal refund with explicit owner approval. Use when the user says "draft a response," "answer this customer," "where's my order," or "I want a refund."

Prepares tax-season materials for small business owners — framed as deliverables for their accountant, not tax advice. Two modes: (1) quarterly estimated tax calculation — pulls YTD net income from QuickBooks and calculates the federal income tax + self-employment tax liability and quarterly payment due; (2) year-end 1099 prep — scans QuickBooks, PayPal, and Stripe for contractors paid over $600, builds a 1099-NEC candidate list with missing W-9 flags, and produces a plain-English summary a CPA can work from directly. Trigger this skill whenever the user mentions: quarterly taxes, estimated tax payment, how much to set aside for taxes, 1099s, 1099-NEC, year-end tax prep, contractor payments, W-9s, or any phrase suggesting they are preparing for a tax deadline or handing materials to an accountant. Also trigger proactively when a user asks about net profit or YTD income in a context that suggests they are worried about their tax bill.

The front door to the Small Business plugin. Listens to what the owner needs right now — vague or specific — and routes them to the best skill or slash command for the moment. Also serves as a guide: explains what's available, suggests what to try next, and adapts recommendations based on stored business context. Trigger whenever the owner asks "what can you do," "help me with my business," "what should I focus on," "I don't know where to start," or any open-ended business request that doesn't clearly match a single skill.
