What iii-sdk-reference does

The skill contains API correspondence tables by language, code examples for each platform, and language-specific caveats. Covers package installation, worker initialization, local function and trigger registration, observers, invocation, logging, and OpenTelemetry support.

Node.js notes custom headers and HTTP-invoked functions; browser documents mandatory rbac-proxy and currentInvocation() limits after the first await; Python distinguishes trigger() from trigger_async(); Rust requires error type mapping and explains local dispatch behavior; Go passes context to Trigger. Helper packages for logging, HTTP, and observability install separately per language.

Refers to iii-core-primitives for the common model and iii-error-handling for exception handling.

What it helps with

  • find the correct function registration syntax for your language
  • understand API differences between Node.js, Python, Rust, and Go
  • connect browser SDK securely through rbac-proxy
  • call async trigger from a Python handler
  • set up OpenTelemetry and structured logging

Example prompts for the agent

  • How do I register a function in iii SDK on Python?
  • What is the difference between trigger and trigger_async in Python?
  • How do I connect the browser SDK to iii?
