When should I use this skill?

Use it when configuring Bazel, implementing remote execution, or optimizing build performance for enterprise codebases.

Does it support remote caching and execution?

Yes. The skill includes patterns for configuring remote caching and remote execution in large monorepos.

Can it help write custom Bazel rules?

Yes. It provides patterns and worked examples for writing custom Bazel rules.

Where are the templates and worked examples?

They live in a reference file called references/details.md, which the agent reads when concrete templates are needed.

Bazel Build Optimization

SkillAI & models

Bazel build optimization is a skill that guides an AI agent through configuring Bazel for large monorepos. It covers workspace setup, remote caching and execution, custom rules, and build performance tuning. The agent uses its patterns and reference examples to help you set up and speed up Bazel builds in enterprise codebases.

What your AI can do with it

Set up Bazel workspaces for monorepos
Configure remote caching and remote execution
Write custom Bazel rules
Optimize build times with fine-grained targets
Debug Bazel build issues
Migrate an existing build to Bazel

Getting started

Have a Bazel project or monorepo that you want to configure or speed up.
Add the skill to your agent so it can read the Bazel patterns and reference file.
Ask the agent to review your WORKSPACE.bazel, .bazelrc, and BUILD files.
Have the agent apply the templates and best practices to your build configuration.
Run your Bazel build and check that caching and target setup work as intended.

Core Concepts

1. Bazel Architecture

├── WORKSPACE.bazel       # External dependencies
├── .bazelrc              # Build configurations
├── .bazelversion         # Bazel version
├── BUILD.bazel           # Root build file
├── apps/

2. Key Concepts

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

Templates and detailed worked examples

Full template library and detailed worked examples live in references/details.md. Read that file when you need the concrete templates.

Best Practices

Do's

Use fine-grained targets - Better caching
Pin dependencies - Reproducible builds
Enable remote caching - Share build artifacts
Use visibility wisely - Enforce architecture
Write BUILD files per directory - Standard convention

Don'ts

Don't use glob for deps - Explicit is better
Don't commit bazel-* dirs - Add to .gitignore
Don't skip WORKSPACE setup - Foundation of build
Don't ignore build warnings - Technical debt
