Browse reusable Agent Skills, each with a clear purpose and practical guidance.
MANDATORY: Activate this skill ANY TIME you need to build the project, run tests, or verify code health in DevTools. You MUST use this skill before executing commands like npm test, npm run build, autoninja, or linters, as it contains critical, repository-specific instructions on how to correctly format these commands, filter test runs, and interpret failures.
Use this skill when unskipping a test that was previously skipped.
Migrating unit tests to foundation unit tests using TestUniverse and devtools_foundation_module. Use when moving tests away from DOM-heavy helpers like describeWithEnvironment or describeWithMockConnection.
Backport a merged kumahq/kuma PR to release branches end-to-end — trigger the backport workflow if needed, find the generated backport PRs, resolve cherry-pick conflicts (module-path rewrites, older APIs), fix DCO, build+test per branch, force-push, clean up PR descriptions/labels, mark ready, and watch CI. Use whenever the user gives a kuma PR link and mentions backporting, backport PRs, cherry-pick conflicts on release-X.Y branches, or asks to fix CI on chore/backport-* PRs.
Workflow for merging a DevTools submodule into its parent module. Covers BUILD.gn consolidation and updating devtools_grd_files.gni.
Reproduce and investigate flakiness in a test.
Consolidates manual DOM creation, updates, and constructors into private helper methods and structured state interfaces.
High-level orchestrator for managing multi-pass migration of Chrome DevTools legacy components to the modern UI engineering vision (UI.Widget & Lit-html).
Scaffolds unit tests and screenshot tests to establish visual and functional rendering baselines for views before refactoring.
Promotes legacy views to modern UI.Widget classes, hooks up performUpdate() rendering, and exports default views.
