Two Personalities for Claude Code — A Morning and Afternoon Workflow That Separates Exploration from Implementation

Treating Claude Code as a different persona in the morning and afternoon stabilises design decisions. A solo developer's six-month run with two CLAUDE.md files, a switching script, and the failure modes I hit along the way.

Make Claude Your Production Debugging Companion: A Practical Design for Log Triage, Hypothesis Generation, and Repro Scripts

A field-tested blueprint for solo developers who carry their own pager. We split production debugging into three jobs Claude can actually own — log summarization, hypothesis generation, and minimal repro — with full prompts, sanitization code, and traps that cost me real downtime.
