Concrete operating rules

Each cookbook gives Claude Code the boring constraints that keep edits reviewable.

Before changing production code:
1. identify the failing test or missing coverage
2. add or update the test first
3. make the smallest code change
4. run the targeted test
5. summarize behavior, not files touched

Stack-specific guidance

React, Python, TypeScript, Go, Rust, Java, MCP, and testing each get their own workflows.

For Next.js app router:
- do not assume cookies() is sync
- keep server/client boundaries explicit
- verify loading and error states
- avoid hidden hydration mismatches

Built from the same VM workflow

These patterns came out of the automation system that built and shipped this catalog.

operator loop:
  read state
  pick one action
  edit files
  run checks
  update ledger
  queue public actions for approval
Simple guarantee: if a cookbook does not save you at least five hours of Claude Code setup and review-loop work, email [email protected] and I will refund it.
