Fetch and analyze code coverage data from Codecov for the LinkML project.

When to Use This Skill

• Before creating a PR: check that coverage won't decrease
• When adding new code: identify if new files need tests
• When asked about test coverage or low-coverage areas

Coverage Expectations

PRs must not decrease coverage. The CI will flag coverage decreases.

When adding new code:

• New modules should target >80% coverage
• New public functions need at least one test
