python-logging-best-practices is agent-read markdown (skill) from terrylica/cc-skills: Python logging with loguru, structlog, and orjson. TRIGGERS - loguru, structlog, structured logging.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Python Logging Best Practices
> **Self-Evolving Skill**: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
## When to Use This Skill
Use this skill when:
- Setting up Python logging for any service or script
- Configuring structured JSONL logging for analysis
- Implementing log rotation
- Choosing between lightweight (zero-dep) and full-featured logging
- Adding logging to containerized, systemd, or local applications
## Overview
Unified reference for Python logging patterns optimized for machine readability (Claude Code analysis) and operational reliability. **Starts with the lightest viable approach and scales up only when needed.**
## Decision Heuristic: Start Light, Scale Up
```
Is it < 5 services on a single machine, < 1 event/sec?
YES → Lightweight Pattern (print + JSONL telemetry)
NO → Is it containerized / serverless?
YES → stdout JSON (any library), no file rotation
NO → Is OTel tracing required?
YES → structlog + OTel
NO → loguru (CLI tools) or stdlib RotatingFileHandler
```

How to install
mdr add terrylica/cc-skills/python-logging-best-practices@git:20260527.3aeb159mdr add terrylica/cc-skills/python-logging-best-practices@sha256:f7800f7c7b5308bcPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
