Table of Contents
TypeScript Conventions
Read when writing, reviewing, or refactoring TypeScript code. Covers strictness posture, the any escape hatch policy, return type inference, interface vs type usage, and naming conventions.
Git Workflow
Read when creating commits, branches, or preparing changes for review. Covers conventional commits, atomic commit discipline, and branch naming patterns.
Testing Principles
Read when writing tests, discussing test strategy, or evaluating coverage. Covers framework-agnostic testing principles. Note: specific test frameworks and tooling are defined in the XY Toolchain skill (Layer 2).
Development Workflow
Read before running any build, lint, or test command, and before declaring any task complete. Covers native toolchain discovery (use the repo's commands, not ad-hoc one-offs) and the definition of done checklist.
