What problem does it solve? Products often need backend logic — calling third-party APIs, enforcing ownership or credits, verifying webhook signatures, performing atomic multi-step writes — without hosting a dedicated backend server. This Skill teaches how to build Weegloo Scripts: declarative, statement-based endpoints stored in a Space that run server-side and return results over an ordinary HTTP call. ## Core Features & Use Cases - Statement-based backend logic: Compose sequences of ResourceRead/Find/Create/Update/Patch/Delete, Http, EmailSend, SetVar, Cache, ParseJson, Signature, Hash, Regex, If/Loop/Parallel/Try, and Return statements with { /pointer } value expressions and JsonLogic operators. - Security patterns: Verify inbound webhook signatures with HMAC Signature statements, gate anonymous edit/delete on caller-supplied secrets, and delegate one privileged operation to low-privilege callers via author-delegated execution. - Concurrency and reliability: Use optimistic locking with sys.version, Try/catch compensation for all-or-nothing multi-step work, and the directCallEnabled/anonymousCallEnabled flags to control invocation. - Use Case: On Content.Publish, a Webhook triggers a Script that POSTs the item to a search-index API, then patches an indexedAt value back onto the content — all server-side with no backend to host. ## Quick Start Ask the agent to create a Weegloo Script that verifies an inbound webhook HMAC signature and writes the payload into a Content entry.
