platform-soql-query: Salesforce SOQL Query Expert
Use this skill when the user needs SOQL/SOSL authoring or optimization: natural-language-to-query generation, relationship queries, aggregates, query-plan analysis, and performance/safety improvements for Salesforce queries.
When This Skill Owns the Task
Use platform-soql-query when the work involves:
.soql files
- query generation from natural language
- relationship queries and aggregate queries
- query optimization and selectivity analysis
- SOQL/SOSL syntax and governor-aware design
Delegate elsewhere when the user is:
Required Context to Gather First
Ask for or infer:
- target object(s)
- fields needed
- filter criteria
- sort / limit requirements
- whether the query is for display, automation, reporting-like analysis, or Apex usage
- whether performance / selectivity is already a concern
Recommended Workflow
1. Generate the simplest correct query
Prefer:
- only needed fields
- clear WHERE criteria
- reasonable LIMIT when appropriate
- relationship depth only as deep as necessary
2. Choose the right query shape
| Need |
Default pattern |
| parent data from child |
child-to-parent traversal |
| child rows from parent |
subquery |
| counts / rollups |
aggregate query |
| records with / without related rows |
semi-join / anti-join |
| text search across objects |
SOSL |
3. Optimize for selectivity and safety
Check:
- indexed / selective filters
- no unnecessary fields
- no avoidable wildcard or scan-heavy patterns
- security enforcement expectations
4. Validate execution path if needed
If the user wants runtime verification, hand off execution to:
High-Signal Rules
- never use
SELECT * style thinking; query only required fields
- do not query inside loops in Apex contexts
- prefer filtering in SOQL rather than post-filtering in Apex
- use aggregates for counts and grouped summaries instead of loading unnecessary records
- evaluate wildcard usage carefully; leading wildcards often defeat indexes
- account for security mode / field access requirements when queries move into Apex
Output Format
When finishing, report in this order:
- Query purpose
- Final SOQL/SOSL
- Why this shape was chosen
- Optimization or security notes
- Execution suggestion if needed
Suggested shape — use references/soql-syntax-reference.md for exact syntax:
Query goal: <summary>
Query: <soql or sosl>
Design: <relationship / aggregate / filter choices>
Notes: <selectivity, limits, security, governor awareness>
Next step: <run in platform-data-manage or embed in Apex>
