Names the domain ('Python SDK for the iii engine') and some actions ('building workers, registering functions, invoking triggers'), but these are somewhat abstract and not fully concrete—e.g., what does 'building workers' entail specifically?

Clearly answers both 'what' ('Python SDK for the iii engine') and 'when' ('Use when building workers, registering functions, or invoking triggers in Python'), with an explicit 'Use when...' clause.

Includes relevant keywords like 'Python', 'SDK', 'workers', 'functions', 'triggers', and 'iii engine', but these are fairly technical and may miss natural user phrasing variations. A user might say 'iii Python library' or 'iii API' which aren't covered.

The combination of 'iii engine', 'Python SDK', 'workers', 'registering functions', and 'invoking triggers' creates a very specific niche that is unlikely to conflict with other skills.

The content is mostly efficient with a good reference table and concise code examples, but the 'When to Use' and 'Boundaries' sections are boilerplate that Claude doesn't need, and some notes could be tightened (e.g., the trigger_async vs trigger explanation is somewhat redundant with the examples).

Provides some executable code examples for register_function, trigger, and trigger_async, but lacks a complete minimal working example (e.g., full worker setup with register_worker through to keeping the event loop alive). The channels section describes API surface without executable code.

There's no explicit step-by-step workflow for setting up a worker from scratch (install → register_worker → register_function → keep alive). The pieces are present but scattered across sections without a clear sequenced workflow or validation checkpoints.

The Pattern Boundaries section provides clear, one-level-deep references to related skills for specific topics (channels, error handling, HTTP middleware, etc.). The main content serves as a concise overview with appropriate pointers to detailed materials and external docs.
