Instrument a Runtime Action

Instrument one App Builder runtime action at a time. Start from the observability goal and add the minimum code needed.

Skip phases that are already answered. If the first message already identifies the action, goal, and requested code changes, implement directly.

For fixed-choice questions, use the runtime's selectable-question tool.

Scope

Work on one action per session. If the user asks for multiple actions or "the whole project," have them choose the first action and continue one at a time.

Key Principles

• Keep one shared defineTelemetryConfig and branch on params or isDev inside it. Separate config files are rare (see references/implementation-patterns.md).
• If API shape or OTel behavior is unclear, use references/documentation-sources.md.
