Agentic Coding Recommendations (via) There's a ton of actionable advice on using Claude Code in this new piece from Armin Ronacher. He's getting excellent results from Go, especially having invested a bunch of work in making the various tools (linters, tests, logs, development servers etc) as accessible as possible through documenting them in a Makefile.
I liked this tip on logging:
In general logging is super important. For instance my app currently has a sign in and register flow that sends an email to the user. In debug mode (which the agent runs in), the email is just logged to stdout. This is crucial! It allows the agent to complete a full sign-in with a remote controlled browser without extra assistance. It knows that emails are being logged thanks to a
CLAUDE.md
instruction and it automatically consults the log for the necessary link to click.
Armin also recently shared a half hour YouTube video in which he worked with Claude Code to resolve two medium complexity issues in his minijinja
Rust templating library, resulting in PR #805 and PR #804.
