Data Triage

Workflow

Note: before you kick off any data-related skills or subagents, run this query using the Snowflake MCP to determine the current day/year.

SELECT current_timestamp()::string AS current_time

If the user's query has ambiguity around the day or year (e.g., "why did query counts drop on 1/15"), assume they're referring to the year returned by the query above.

Data Questions (Snowflake — Default)

You have a few specialized skills and subagents available to you. For any data-related question, you must always start with the data-model-explorer subagent so you can build a foundational understanding of what data is available. NEVER call data-analyst or any other downstream data tool without first calling data-model-explorer.

CRITICAL: Retrieving data-model-explorer Output

After calling data-model-explorer, ALWAYS read the output from the file it writes:

/tmp/data_model_explorer_output.txt

Use the Read tool to retrieve this file's contents. Do NOT rely on TaskOutput or the Task return value — it may fail. The file contains the complete data model findings that you MUST pass to downstream skills.

Workflow:

1. Call data-model-explorer subagent
2. Read /tmp/data_model_explorer_output.txt using the Read tool
3. Pass the COMPLETE file contents to downstream skills (data-analyst, etc.)

Once you've retrieved the output from data-model-explorer, you have a range of options:

• For questions that are about the data model itself (e.g., "do we have a table that holds data on X?" or "what columns are available for Y?"), you can return the explorer's findings directly without calling another skill.
• If a user asks a question that requires analysis (even if just a single query), such as "how many X?" or "count of Y?", you MUST call data-analyst after data-model-explorer. Even if data-model-explorer has already provided context, you MUST delegate all query execution to data-analyst because it has special instructions for performing analysis correctly.

NEVER run SQL queries yourself. Even if data-model-explorer provides a sample query, you MUST delegate all query execution to data-analyst.

• If the user is asking why a metric changed, dropped, increased, or is behaving unexpectedly, still use the data-model-explorer -> data-analyst workflow. Pass along the investigative nature of the question so that data-analyst knows to perform segment analysis and root cause investigation. Examples:
  • "Why did DAU drop yesterday?"
  • "What caused the spike in queries?"
  • "Conversion rate is down, can you investigate?"
  • "Something's wrong with our revenue numbers"

Principles to keep in mind:

• CRITICAL: Do NOT construct SQL queries yourself. Your job is to pass complete, unsynthesized, unedited outputs of upstream tasks or skills to downstream tasks and skills. When calling a task or skill after data-model-explorer has run:

1. Include the user's original question
2. Copy the COMPLETE, VERBATIM output from data-model-explorer (tables, columns, relationships, assumptions — everything)
3. Do NOT summarize, synthesize, or pre-construct any SQL

Let the downstream task or skill determine how to query the data model based on its own knowledge and the explorer's findings.

• Never fabricate data. NEVER pretend to run a query or make up results.
