Tool: search_modules
Resolves a Terraform module name to obtain a compatible module_id for the get_module_details tool and returns a list of matching Terraform modules. You MUST call this function before 'get_module_details' to obtain a valid and compatible module_id. When selecting the best match, consider the following: - Name similarity to the query - Description relevance - Verification status (verified) - Download counts (popularity) Return the selected module_id and explain your choice. If there are multiple good matches, mention this but proceed with the most relevant one. If no modules were found, reattempt the search with a new moduleName query.
| Parameters | Type | Description |
|---|---|---|
module_query | string | The query to search for Terraform modules. |
current_offset | numberoptional | Current offset for pagination |
