Guide for working with Scope, a developer environment management tool that automates environment checks, detects known errors, and provides automated fixes. Use when creating Scope configurations (ScopeKnownError, ScopeDoctorGroup, ScopeReportLocation), debugging environment issues, or writing rules for error detection and remediation.

Guide for creating effective opencode skills. Use when users want to create a new skill (or update an existing skill) that extends agent capabilities with specialized knowledge, workflows, or tool integrations.

Use when writing unit tests for Angular components, services, pipes, or directives. Triggers on requests to "write tests", "add tests", "create spec", "test this component", or when test files need to be created/modified.

Automate GitHub pull request review resolution by processing ALL review comments and fixing ALL failing CI checks. Use when: (1) A PR has review comments that need to be addressed and resolved, (2) CI/CD checks are failing and need fixes, (3) You want to process all PR feedback and mark conversations as resolved, (4) You need to iterate on PR feedback quickly. IMPORTANT: This skill processes EVERY comment - no skipping allowed. Always fetches fresh data from GitHub. The only acceptable end state is zero unresolved threads. COMMIT CADENCE: Each thread gets its own commit (fix → commit → resolve → next). Never batch commits at the end.
