Recreate Figma design frames as prototype-ready Chromium Views JSON script following Chrome's native Views architecture, component guidelines, and color/shape token mappings. Use when asked to create C++ Views Prototype JSON script from a Figma frame URL.
Recreate Figma design frames as production-ready Chromium WebUI code following Chrome's Lit-element architecture and styling guidelines. Use when asked to create WebUI code from a Figma frame URL.
Finds common violations of the Android accessibility API in the Clank App Java code and attempts to address them (e.g. hardcoded state change announcements, missing events, focus moving, assertive live regions, etc).
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.
Extension pipeline to bump expiration dates of Chromium UMA histograms.
Orchestrator for the "Code Health Hub" framework. Trigger only when the user refers to the Hub or asks to see "available cleanup tasks" within the Chromium technical debt reduction system.
Identify and clean up inline fully qualified Java names (FQNs) in first-party code, replacing them with standard imports.
Automatically detects misordered lists in code (like Android XMLs), injects go/keep-sorted tags, sorts them, and creates CLs.
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.
Replace anonymous classes with lambdas where applicable (SAM interfaces)
Extracts raw trace data from Perfetto traces, runs arbitrary SQL queries for custom follow-up analysis, and applies expert cognitive principles (Tiered Flow Analysis, Semantic Mismatch, Redundancy) to identify performance bottlenecks, structural redundancies,…
Automated Tracing & Performance Telemetry in Chromium using Perfetto and Telemetry benchmarks. Use when you need to launch the browser binary, execute a specific scenario/story, and collect Perfetto traces. Don't use for trace analysis (use…
Toggle ChromeVox screen reader on ChromeOS devices and send raw keyboard input events. Use when debugging accessibility features on an external ChromeOS device, needing to enable or disable ChromeVox, or sending specific keys to the system via SSH.
Search and reference Chromium documentation from the local docs index, including design docs, APIs, and development guides. Use when the user asks to find, locate, browse, or learn from Chromium docs about architecture, APIs, testing, GPU, networking, or…
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.
Multi-agent consensus-driven code review. Audits changes using security, performance, and style checkers.
Enforce engineering rigor and verification loop for coding tasks using multi-agent debate and TDD.
Cleans up the workspace, formats code, runs presubmit checks, and uploads CLs to Gerrit.
Guide and tools for creating coordinated multi-agent workflows (skills) from first principles.
Updates checklists and personas for multi-agent skills.
Multi-agent Test-Driven Development workflow. Scaffolds APIs, writes failing tests, synthesizes implementation, and verifies compilation and test runs.
Look through a given folder to find and safely remove unused includes specifically for Clang-compiled code (using clang-include-cleaner), verifying that referencing targets compile.
Adds scaffolding for a new Sync data type in Chromium across protocol buffers, DataType definitions, feature flags, controller builders, unit tests, and metrics.
Critique and review Figma designs to ensure alignment with Chromium codebase components, tokens, and structure. Use when the user asks to critique, review, or audit a design, check alignment with code, or compare a Figma node against component specifications…
Recreate Figma design frames as production-ready Chromium C++ Views code following Chrome's native Views architecture, component guidelines, and color/shape token mappings. Use when asked to create C++ Views code from a Figma frame URL.
Maps a Figma component from the Chrome Design System (CDS) to equivalent C++ Views and WebUI components in the Chromium codebase. Generates a comprehensive side-by-side comparative Markdown specification detailing layout variants, interactive states, design…
Maps all Figma design tokens from figma-variables.md to their equivalent C++ (Views) identifiers and CSS (WebUI) variables in Chromium, and saves the formatted mapping table to the assets directory of the Chrome Design System project. Use this skill when…
Use this skill whenever you need to look up or reference Chrome Design System component specs or design token mappings.
Runs code coverage locally via Universal Test Runner (UTR) or helper scripts, mimicking LUCI trybots. Activate when CQ tryjobs fail or underreport coverage, to test local GN/recipe repairs before uploading, or to debug hermetic crashes.
Enforce engineering rigor and verification loop for coding tasks using multi-agent debate and TDD.
Guide for writing and converting Chromium Android unit tests across host Robolectric (chrome_junit_tests) and on-device (chrome_public_unit_test_apk) suites.
Use this skill to get a link to a Gerrit Changelist (CL) from a given commit hash in the Chromium repository. Use when you need to find the review discussion, comments, or related issues for a specific commit. Don't use for linking to files or code lines.
Guide for auditing and applying batching annotations (@Batch) and AutoReset rules (AutoResetCtaTransitTestRule) to Android javatests in Chromium. Use this skill when optimizing Java instrumentation test runtimes, resolving test state leaks, or migrating tests…
Validates Chromium generated builder configurations (gn-args.json) for code coverage correctness based on language context.
Verifies and initializes the Chromium development environment and dependencies required for running code coverage tools and services.
Triages Chrome code coverage bugs, initializes the environment, and delegates to the appropriate debugging sub-agent (CQ or CI) using a shared state file.
Inspects LUCI build details using the inspect_coverage_build.py script to validate code coverage configurations, test execution, and target file coverage.
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.
Finds the executable test suites (e.g., `browser_tests`, `unit_tests`) responsible for compiling and executing a specific target source code file or test file in Chromium on Linux.
