Bazel Build Optimization
Bazel Build Optimization is an design AI skill with a core value of Optimize Bazel builds for large-scale monorepos. It
helps developers solve real-world problems in the design domain, boosting
efficiency, automating repetitive tasks, and optimizing workflows.
Optimize Bazel builds for large-scale monorepos. Use when configuring Bazel, implementing remote execution, or optimizing build performance for enterprise codebases.

# Bazel Build Optimization
Production patterns for Bazel in large-scale monorepos.
Do not use this skill when
- The task is unrelated to bazel build optimization
- You need a different domain or tool outside this scope
Instructions
- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
- If detailed examples are required, open `resources/implementation-playbook.md`.
Use this skill when
- Setting up Bazel for monorepos
- Configuring remote caching/execution

| Concept | Description |
|---------|-------------|
| **Target** | Buildable unit (library, binary, test) |
| **Package** | Directory with BUILD file |
| **Label** | Target identifier `//path/to:target` |
| **Rule** | Defines how to build a target |
| **Aspect** | Cross-cutting build behavior |
