get_type_dependencies

[architecture]

Analyzes type dependencies (uses / used_by).

Parameters

Name	Type	Required	Description
symbolKey	string	No	Source type key from discovery. Do not combine with typeName or projectName.
typeName	string	No	Type name. Provide this or symbolKey.
projectName	string	No	Optional project name filter.
direction	string	No	Direction: 'uses', 'used_by', or 'both' (default). Default: `"both"`
responseDetail	string	No	compact returns results and actionable state. full adds diagnostic metadata under responseDiagnostics. Default: `"compact"`

Examples

Replace sample paths and symbol keys with values from your workspace.

Response Notes

Returns types used by the target and types that reference it. The target and source dependency records include symbolKey. External dependency keys are null. Keys select source types only; stale, metadata, and non-type keys fail. Results use top-level fields with success. Compact is the default; full adds responseDiagnostics. Both modes retain errors, coverage, partial state, and recovery advice.
