Add-on: Python Observability with structlog

Use this skill when a Python runtime needs package-backed structured logging. This is the default implementation add-on for Python when addon-observability-telemetry is in scope.

Compatibility

• Best fit for architect-python-uv-fastapi-sqlalchemy.
• Also valid for architect-python-uv-batch and Python worker-style projects.
• Pairs cleanly with addon-observability-telemetry, which defines the higher-level telemetry contract.

Inputs

Collect:

• TELEMETRY_MODE: logs-only | logs+metrics | logs+metrics+traces.
• LOG_FORMAT: json | logfmt.
• PII_REDACTION: strict | standard.
• PYTHON_OBSERVABILITY_PROFILE: api | worker.
• LOG_BACKEND: default structlog; only use loguru when the user explicitly requests it and the tradeoff is documented.
