Skill Testing: Validate Before Publishing
Ensure your custom skills work reliably by following a structured testing process. Validate functionality, edge cases, and documentation before publishing.
What You Will Get
After this guide, you will have a systematic process for testing custom skills before publishing or sharing them. You will catch bugs, edge cases, and documentation gaps before users encounter them. A well-tested skill installs cleanly, works reliably, and earns positive ratings.
Skill testing is different from traditional software testing. You are testing both the code logic (if any) and the documentation quality, because the agent's behavior depends on how well the SKILL.md communicates instructions. A technically correct skill with unclear documentation will still fail in practice.
The testing process covers five areas: installation testing, happy path testing, edge case testing, error handling testing, and documentation accuracy testing. Covering all five ensures your skill is robust enough for production use and community sharing.
How to Test Your Skills
A structured testing process for reliable skills
Test Clean Installation
Start by testing that the skill installs correctly from scratch. Remove any existing installation and install fresh. Verify that the skill appears in the active skills list, all configuration prompts work correctly, and required dependencies are detected and handled. Document any installation steps that are unclear or confusing.
Test the Happy Path
Run the skill's primary use case with ideal input. If it is a code review skill, submit a clean PR for review. If it is a monitoring skill, trigger the event it watches for. Verify the output matches expectations: correct format, accurate content, and appropriate timing. This confirms the basic functionality works.
Test Edge Cases
Try inputs that push the boundaries. Empty input, very large input, unusual characters, unexpected formats, and inputs that technically match the trigger but are not the intended use case. A robust skill handles these gracefully, either processing them correctly or informing the user that the input is not supported.
Test Error Handling
Deliberately trigger error conditions. Disconnect the external service, provide invalid credentials, exceed rate limits, or send malformed data. Verify that the skill reports errors clearly without crashing, exposing sensitive information, or entering an infinite retry loop. Every error condition should produce a user-friendly message.
Test Documentation Accuracy
Read through the SKILL.md and verify every claim. If the documentation says the skill posts review comments on PRs, confirm it actually does. If it says it supports three output formats, test all three. Documentation inaccuracies erode user trust and generate support requests.
Test with a Fresh Perspective
Ask a colleague or friend who has not seen the skill before to install and use it following only the documentation. Observe where they get confused, what steps they skip, and what questions they ask. Their fresh perspective reveals documentation gaps that you, as the creator, are blind to.
Run the Publishing Validator
Before publishing, run the ClawHub publishing validator. It checks for required files, metadata completeness, and common structural issues. Fix any validation errors. Even if your skill passes all functional tests, a failed validation prevents publishing and means something structural needs attention.
Tips and Best Practices
Create a Test Checklist
Build a checklist specific to your skill that covers every feature, configuration option, and error scenario. Run through the checklist before every release. Checklists prevent you from skipping tests when you are in a hurry to publish.
Test in a Clean Environment
Test your skill on a fresh OpenClaw instance without your other skills installed. This reveals dependencies on skills or configurations that exist in your environment but not in a typical user's environment.
Automate Repetitive Tests
For skills that you update frequently, create a set of test scenarios that you can run quickly. Save the test inputs and expected outputs so you can repeat them after every change. This regression testing catches bugs introduced by updates.
Test Version Upgrades
If you are publishing an update, test the upgrade path from the previous version. Verify that existing configurations are preserved, new features work alongside old ones, and nothing breaks for users upgrading from the last version.
