Identify and safely remove expired Chromium histograms (dead metrics/technical debt). Use this skill when a contributor asks to clean up metrics, fix code health issues related to histograms, remove obsolete code, or work on a histogram cleanup task.

Identify and clean up inline fully qualified Java names (FQNs) in first-party code, replacing them with standard imports.
Add missing LINT.IfChange(...) / LINT.ThenChange(...) guards to enums in C++/Java and XML to keep them in sync. Trigger this skill ONLY when a contributor explicitly asks to add lint guards or synchronize enums using LINT guards.
Checks if a Chromium test suite is barred by `ci_only = True` configuration on coverage trybots, which prevents the test suite from running automatically on Gerrit CQ runs and can cause underreported code coverage.
Executes the phased, multi-skill code coverage debugging playbook for triaging underreported code coverage in the Gerrit Commit Queue (CQ).
Validates code coverage Swarming execution logs, CAS input/output profile artifacts, and profile generation environments to isolate remote trybot code coverage failures.
