resolveProviderDocID
This tool retrieves a list of potential documents based on the serviceSlug and providerDataType provided. You MUST call this function before 'getProviderDocs' to obtain a valid tfprovider-compatible providerDocID.
Use the most relevant single word as the search query for serviceSlug, if unsure about the serviceSlug, use the providerName for its value.
When selecting the best match, consider: - Title similarity to the query - Category relevance Return the selected providerDocID and explain your choice.
If there are multiple good matches, mention this but proceed with the most relevant one.
searchModules

You MUST call this function before 'moduleDetails' to obtain a valid and compatible moduleID. When selecting the best match, consider: - Name similarity to the query - Description relevance - Verification status (verified) - Download counts (popularity) Return the selected moduleID 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.
