Spectrum

Spectrum is Photon's unified messaging SDK. Write handler logic against one app.messages stream and deliver it through iMessage, WhatsApp Business, Terminal, or a custom provider. This skill targets spectrum-ts 12.2.0; its code samples are TypeScript.

Contract gate

Identify the provider and load its topic file before writing provider-specific code. A sample is complete only when every import, method, content shape, platform ID, fallback, and thrown error belongs to spectrum-ts 12.2.0 and the selected provider contract. The universal method existing does not prove that every provider implements it; read capability-semantics.md whenever support affects correctness.

How this skill is organized

Each topic lives in its own file in this directory. Read the file relevant to the user's question.
