What problem does it solve? AI coding agents hallucinate Twilio SDK signatures, wire names, and error types when writing C# integration code, producing compile errors and broken API calls. This Skill routes every Twilio .NET SDK need through a dedicated twilio-sdk subagent that grounds answers in a bundled SDK map, so the main agent implements from an authoritative contract sheet instead of memory. ## Core Features & Use Cases - Plan-first workflow: Spawns the twilio-sdk agent once to produce a twilio-plan.md contract sheet with exact signatures, wire names, envelope shapes, error accessors, and enum values before any code is written. - Hard safety gates: Blocks project-file edits while the agent runs, requires the plan file to exist and be read before coding, and mandates loading every dotnet-* companion skill the contract sheet names. - Error handoff: Routes compile or runtime errors on SDK types (CS1061, CS0234, provider errors) back to the warm agent for in-place fixes instead of guessing. - Use Case: A developer asks their agent to add SMS sending and OTP verification to an ASP.NET Core app; the Skill spawns the twilio-sdk agent, receives a contract sheet, loads the named dotnet-* skills, and implements the integration step by step with build verification. ## Quick Start Ask your agent to integrate Twilio SMS sending into your C# project and load this Skill first so it delegates planning to the twilio-sdk agent.
