find_implementations

[references]

Finds implementations of an interface/abstract type or member. Requires a symbolKey.

Parameters

Name	Type	Required	Description
symbolKey	string	Yes	Opaque symbolKey from search_symbols, resolve_symbol, get_symbol_at_position, or any tool that returns symbolKey. Not a name.
scope	json	No	Optional scope. Omit scope to search the solution. When supplied, set mode to solution, project, document, or pathPrefix. project requires projectName. document requires filePath. pathPrefix requires pathPrefix. Paths can be absolute or relative to solutionRoot. Set includeExternal to true when the tool supports external symbols.
pathStyle	string	No	Path style: 'absolute' (default) or 'relative' (to solution root). Default: `"absolute"`
skip	number	No	Pagination offset. Default is 0. Default: `0`
take	number	No	Pagination size. Default is 200. Default: `200`
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 implementing symbols (with paging) Results use top-level fields with success. Compact is the default; full adds responseDiagnostics. Both modes retain errors, coverage, partial state, and recovery advice.
