get_type_info

[analysis]

Gets detailed information about a type (members, inheritance, interfaces, docs, and location).

Parameters

Name	Type	Required	Description
typeName	string	No	Type name (simple or fully qualified). Provide this or symbolKey.
symbolKey	string	No	A key returned by find_code. Pass it unchanged. Provide this or typeName.
projectName	string	No	Optional project name filter.
includeMembers	boolean	No	Include member list in response. Default is true. Default: `true`
maxMembers	number	No	Maximum number of members to return. Default is 100. Default: `100`
memberKinds	string	No	Filter members by kind, comma-separated: 'Method', 'Property', 'Field', 'Event', or 'Constructor'.
pathStyle	string	No	Path style: 'absolute' (default) or 'relative' (to solution root). Default: `"absolute"`
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 type details including members and inheritance. declaredBaseType names the base a class declares when the compiler rejected it (an illegal base), otherwise null. If a key does not resolve, discover the type again with find_code. Results use top-level fields with success. Compact is the default; full adds responseDiagnostics. Both modes retain errors, coverage, partial state, and recovery advice.

For a failed symbol-key request, success=false includes errorCode, parameter, error, and suggestions in compact, full, and batch operation results. Batch keeps a bounded summary outside the requested detail budget. If the hard server limit omits details, failureDetailsOmitted or writeStateOmitted identifies the omission. errorCode is invalid_symbol_key, symbol_not_found, ambiguous_symbol_key, wrong_symbol_kind, source_unavailable, unsupported_symbol, or invalid_arguments. Follow the suggestions for the specific failure. Correct the named selector for invalid_arguments. For symbol_not_found, repeat discovery in the selected workspace and pass a returned key unchanged. An absent identity does not prove that a key is stale.
