Recce Quick Guide

When to Activate

Activate this skill when you detect:

1. dbt project detected - Working directory contains dbt_project.yml
2. PR/code review discussion - User mentions "PR", "pull request", "code review", "merge request"
3. Data comparison needs - User mentions "diff", "compare", "changes", "before/after"
4. dbt command execution - User runs dbt run, dbt build, dbt test
5. Data quality questions - User asks about data validation, data quality, testing data

Available Commands

When in a dbt project, inform the user about these commands:

• /recce-setup - One-click environment setup for Recce
• /recce-pr - Analyze PR data impact
• /recce-check - Run data validation checks

Available Recce MCP Tools

When Recce MCP Server is running (check with bash ${CLAUDE_PLUGIN_ROOT}/scripts/check-mcp.sh):

Tool	Purpose	Key Parameters
lineage_diff	Model changes and lineage impact	select, exclude, view_mode
schema_diff	Column structure changes	select, exclude
row_count_diff	Row count comparison	select, exclude
profile_diff	Statistical profile comparison	select, exclude
query	Execute SQL query	sql, base
query_diff	Compare SQL query results	sql
list_checks	List available checks	-
run_check	Execute specific check	check_id

Important Constraints

1. Never use views with these tools: row_count_diff, query, query_diff, profile_diff

   • Views trigger expensive queries
   • Always filter with select:"config.materialized:table"

2. dbt selector syntax supported:

   • state:modified - Only modified models
   • state:modified+ - Modified + downstream
   • tag:xxx - Models with specific tag
   • +model_name - Model + upstream
   • model_name+ - Model + downstream

Contextual Suggestions

When dbt project is detected (SessionStart)

I notice this is a dbt project! I can help you with data validation using Recce.

Try `/recce-setup` to get started, or ask me about:
• Comparing data changes between branches
• Validating PR data impact
• Running data quality checks

After dbt command execution

dbt command completed! Would you like to validate the data changes?

Use `/recce-check` to compare row counts, schemas, and data profiles
between your base and current environments.

When discussing PRs

I can help analyze this PR's impact on your data.

Use `/recce-pr` to see:
• Which models changed
• Schema modifications
• Row count differences
• Downstream impact

Documentation Lookup

When users ask about Recce features, configuration, or usage:

1. Use mcp__recce-docs__searchDocs to find relevant pages
2. Use mcp__recce-docs__getPage to get detailed content
3. Answer based on documentation with source links

Example questions to handle:

• "How do I set up GitHub Actions with Recce?"
• "What is row_count_diff?"
• "How do I compare schemas between branches?"

Cache Management

The docs MCP server manages cache automatically:

• First query: Crawls and indexes docs (~30 seconds)
• Normal use: Local cache, instant response
• Expiry check: Every 7 days checks for updates

If user reports outdated docs, use mcp__recce-docs__syncDocs with force: true.
