LEARN WITH A CLEAR DIRECTION

Agent Skills for Android Developers

Understand skill packages and write reusable Android workflows with clear triggers, scoped instructions, scripts and evaluation cases.

Beginner to IntermediateSelf-paced7 modules13 available lessons

Your path, one skill at a time.

Understand skill packages and write reusable Android workflows with clear triggers, scoped instructions, scripts and evaluation cases. Follow six teaching modules, each with a practical assignment, then combine the skills in the final project. Start with the introduction even if the tools are familiar: it defines the scope and boundaries of the path.

Self-paced. Complete each exercise and use its checkpoint before moving to the next module. Revisit any prerequisite you cannot yet demonstrate.

What you’ll learn

  • The skill activates for intended tasks and stays out of unrelated work
  • Scripts report failures without hiding exit codes
  • Generated changes follow project conventions and include evidence

THE CURRICULUM

Build your knowledge, step by step.

13 lessons across 7 modules. Open a module to explore its lessons and practical work.

01MODULE 01What an agent skill is2 lessons · Self-paced
  • Instructions as a package
  • Skill versus tool
  • Activation scope

Distinguish reusable expertise from tools and model training.

  1. 01What an agent skill isLesson · Self-paced
  2. 02Practice: What an agent skill isLab · Self-paced

Ready to move on when: You can explain why the skill exists separately from the tools it uses.

02MODULE 02Writing the skill entry point2 lessons · Self-paced
  • Metadata and purpose
  • Workflow steps
  • Project constraints

Make the main instructions actionable and easy to follow.

  1. 01Writing the skill entry pointLesson · Self-paced
  2. 02Practice: Writing the skill entry pointLab · Self-paced

Ready to move on when: Another engineer can predict the workflow from the entry point alone.

03MODULE 03References, templates and scripts2 lessons · Self-paced
  • Progressive detail
  • Script contracts
  • Template discipline

Keep specialized detail available without loading everything at once.

  1. 01References, templates and scriptsLesson · Self-paced
  2. 02Practice: References, templates and scriptsLab · Self-paced

Ready to move on when: Supporting files have clear ownership and observable behavior.

04MODULE 04Trust and permission boundaries2 lessons · Self-paced
  • Untrusted content
  • Action scope
  • Secrets and outputs

Prevent a reusable workflow from becoming an unrestricted instruction bundle.

  1. 01Trust and permission boundariesLesson · Self-paced
  2. 02Practice: Trust and permission boundariesLab · Self-paced

Ready to move on when: The skill does not expand authority merely because a reference file requests it.

05MODULE 05Testing activation and outcomes2 lessons · Self-paced
  • Positive and negative cases
  • Outcome rubric
  • Regression fixtures

Evaluate whether the skill improves real engineering work.

  1. 01Testing activation and outcomesLesson · Self-paced
  2. 02Practice: Testing activation and outcomesLab · Self-paced

Ready to move on when: You can identify a skill revision that makes performance worse.

06MODULE 06Packaging and team maintenance2 lessons · Self-paced
  • Portable paths
  • Version ownership
  • Adoption evidence

Make the skill understandable and maintainable by someone else.

  1. 01Packaging and team maintenanceLesson · Self-paced
  2. 02Practice: Packaging and team maintenanceLab · Self-paced

Ready to move on when: The package works without undocumented local state.

07MODULE 07Capstone and portfolio review1 lessons · Self-paced
  • The skill activates for intended tasks and stays out of unrelated work
  • Scripts report failures without hiding exit codes
  • Generated changes follow project conventions and include evidence

Create a reusable Android review skill with instructions, a reference file, a bounded check script and positive and negative activation tests.

  1. 01Capstone: Agent Skills for Android DevelopersProject · Self-paced

Ready to move on when: Demonstrate every acceptance criterion and explain the tradeoffs without relying on the lesson text.

PROVE YOUR SKILLS

A portfolio you can build, explain, and defend.

  • The skill activates for intended tasks and stays out of unrelated work
  • Scripts report failures without hiding exit codes
  • Generated changes follow project conventions and include evidence

Use the final review rubric to identify gaps. Lesson completion tracks study progress; readiness comes from independently demonstrating the work.
