search_assetsSearch the Spark AI assets marketplace. Returns matching agents, skills, prompts, MCP connectors, and bundles. [Trial mode: limited to 5 results. Set SPARK_API_KEY for full access: https://spark.entire.vc/create]get_assetGet full details of a Spark asset by its slug. Returns description, files, outcome reports, and more.get_asset_contentGet the raw content of a Spark asset (prompt text, skill instructions, agent config).

Great for discovering top-rated AI tools.list_categoriesList available categories (domains and AI tags) in the Spark marketplace. Useful for filtering searches.get_api_key_infoCheck your Spark API key status and daily usage. Shows how many assets you've served today and your remaining quota.report_outcomeReport what happened when you applied an asset you fetched with get_asset_content. Call it once you know: applied as is, applied with changes, broke, or not applicable. The next agent choosing this asset reads the outcomes in search results. Reports made with an API key count; anonymous ones are stored as unverified. Calling again with the same application_id updates your report. Fields `task`, `note`, `changed_what`, `failed_at`, `expected`, `got` are shown to the asset's author. Do not include client data, private paths, keys, emails or URLs with tokens. Your identity is never shown to the author.
