MIXINv2 language coding conventions: C#-like UpperCamelCase/lowerCamelCase naming with totality semantics, namespace/sort/entity/algebraic-structure/category concepts, the *Factory + Product pattern, abstract factories with declarations, nested-class projection fields, private underscore members, Python FFI module naming (@public/@resource/@extern), and lexical vs qualified-this references. Use when authoring or editing .mixin.yaml files, MIXINv2 Python FFI modules, or anything in the MIXINv2 scope tree.

Bug investigation workflow using GitHub MCP. Use when users report bugs, errors, or unexpected behavior that need investigation. Handles duplicate checking, incremental issue updates, root cause analysis, and adding diagnostic logging/tests. In this skill's workflow: investigate and document findings, but do NOT fix the bug itself. Other workflows/agents may fix bugs separately.
