Claude Code Infra Showcase — Real-World Setup Patterns

Practical Notes

• Start with 1 repo and 1 workflow (lint/test/fix) before rolling out to all repos.
• Measure impact: PR cycle time and CI failure rate usually change first.

What to copy first (high leverage)

If you only copy one thing, copy the guardrails:

• what agents must run before claiming done,
• what they must never do (prod migrations, destructive ops),
• how to present output (diff, commands, verification).

A minimal “Claude Code team standard”

1. Add a short repo instruction file:

• required commands,
• allowed directories,
• formatting expectations.

2. Provide one “happy path” script:

• run checks,
• apply fix,
• re-run checks.

3. Keep it boring: The goal is consistent delivery, not clever prompts.

Rollout plan

• Pilot on one repo for one week.
• Convert what worked into a template.
• Only then scale to the rest of the org.

FAQ

Q: Is this only for Claude Code? A: It’s Claude Code oriented, but most guardrail patterns apply to any coding agent.

Q: How do I avoid prompt sprawl? A: Keep one canonical instruction file per repo and treat it like code (review changes).

Q: What should I measure after rollout? A: CI failure rate, PR cycle time, and number of reverted agent changes.
