Included Skills1

Name the domain, trace the existing call graph before changing it, then prove each behavior with a test that was red first. Use at the start of every implementation task - feature, bug fix, refactor, migration, CI or infra change - and especially when the task arrives as a product requirement with no technical detail. Also use to resume an in-progress trace, to revalidate one after pulling others' changes, or to audit someone else's change set. Records every decision in an append-only log under .design/ and renders the graph on each one. Tiers: requirement, task, file, symbol, behavior. Works in Go, Rust, Java, TypeScript, JavaScript, Effect, Ruby, Python, Bash, GitHub Actions and Terraform.
