# Logging — Quick Reference

- **Full implementation details: `.claude/skills/walnut-logging/SKILL.md`** (levels, redaction

- patterns, browser log persistence architecture, investigation commands).

+ **Full implementation details: `.claude/skills/walnut-ops/SKILL.md`** (incident investigation

+ playbook, always-on sentinels, levels, redaction patterns, browser log persistence

+ architecture, investigation commands).

## Essentials

- `import { log } from '../logging/index.js'` → `log.<subsystem>.info('msg', { fields })`;

child loggers via `log.agent.child('loop')`. `initLogging()` once at startup.

- All lines pass `redactSensitiveText()` before hitting disk (API keys, AWS creds, bearer

tokens, PEM blocks, `password=`/`token=` values → `[REDACTED]`).

- Browser `console.log/warn/error` are persisted to the same disk log with

`subsystem: 'browser'` (`console.debug` is NOT — never rely on it). Investigate frontend

issues with `walnut logs -s browser` — the disk log survives page refresh.
