Tips, tricks, and chatsnackian prompt composition patterns for YAML-first chat assets, text fillings, chat fillings, includes, thin runtime loaders, and utensils. Use when building or reviewing chatsnack projects, graphical prompt builders, dynamic prompt systems, agentic coding prompts, game-master style agents, benchmark prompt morphs, context aggregation flows, reusable prompt fragments, or consumer code that is tempted to render prompts through private chatsnack hooks such as _build_final_prompt.

Design, implement, review, and document idiomatic snapclass code in this repository. Use when needing lightweight persistence with Python classes, or specifically working with snapclass models, readable YAML/JSON/TOML/text output, stashes, sidecars, Fresh defaults, serializers, formatters, collections, sync/create_model/Model APIs, persistence policy, README examples, or tests that should follow snapclass's dataclass-first file persistence style.
