Effect

Use current Effect v4 APIs and the production defaults in this skill. Established project conventions still take precedence unless the task is explicitly changing them.

Source Rule

Check these before guessing:

• the nearest AGENTS.md and any project-local Effect practices doc
• the project-pinned effect package source and version
• current upstream Effect source when the installed package does not answer the question

Branch Chooser

Read only the branch references that match the task.
