BrowserWorksSkillaccessibility-frontend-review
Performs an accessibility code review of a local diff or Phabricator revision in the style of the Firefox accessibility team. Use this skill whenever the user asks to review a Phabricator patch or revision for accessibility issues, mentions a D-number (like D284142) in the context of accessibility review, asks "does this patch have any a11y issues", or wants to check a diff against accessibility guidelines. Also use it when the user says things like "can you review this for a11y", "check this patch", or "give me an accessibility review of D[number]". Invoke proactively when the user pastes a phabricator.services.mozilla.com URL or shares a revision ID alongside any accessibility concern. Invoke when questions about the following topics are raised: aria properties, aria roles, high contrast mode, forced colors, prefers contrast, focus order, screen readers, assistive technology.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
7 rules. 0 are common, 4 are distinctive, and 3 are very specific to this project.
0
Common
Most of the 10 edited versions we read keep these.
4
Distinctive
This author's own choices. Worth a look.
3
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 49
When the user's task maps to a sub-skill above, read that sub-skill's SKILL.md before writing any code:
- Distinctive: line 56
If the task spans multiple sub-skills (e.g., Compose + Navigation), load both.
- Distinctive: line 60
Always check the sub-skill's Requirements and Verification sections before starting.
- Distinctive: line 61
Prefer Kotlin over Java for all new code.
- Distinctive: line 62
Follow the Modern Android Development guidance.
- Very specific: line 63
Use Gradle version catalog (libs.versions.toml) for dependency management.
- Very specific: line 64
Never run ./gradlew clean unless specifically required — it wastes build time.
“Common” is measured: kept by at least 6 in 10 of the 10 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Android Skills
A comprehensive suite of Android development skills from Google, grounding agents in official Android platform APIs, tooling, and best practices.
Source: developer.android.com
Sub-Skills
Each sub-skill contains its own SKILL.md with a full technical specification.
Load the relevant sub-skill when the task matches:
| Sub-Skill | When to Use |
coding/android/agp-9-upgrade | Migrating a project to Android Gradle Plugin 9. Do not use for KMP projects. |
coding/android/camera | Camera2 or CameraX image/video capture, preview, analysis, extensions. |
coding/android/jetpack-compose | Jetpack Compose UI — layouts, state, theming, animations, interop. |
coding/android/navigation | Navigation component, deep links, multi-back-stack, type-safe routes. |
coding/android/performance | App profiling, startup time, frame rate, memory, battery optimization. |
coding/android/play | Google Play publishing, app bundles, delivery, billing, review policies. |
coding/android/system | Android system APIs — permissions, services, broadcasts, app lifecycle. |
coding/android/xr | Android XR — immersive experiences, spatial UI, ARCore, OpenXR. |
How to Load a Sub-Skill
When the user's task maps to a sub-skill above, read that sub-skill's SKILL.md
before writing any code:
Read skills/coding/android/<sub-skill>/SKILL.mdIf the task spans multiple sub-skills (e.g., Compose + Navigation), load both.
General Android Guidelines
- Always check the sub-skill's Requirements and Verification sections before starting.
- Prefer Kotlin over Java for all new code.
- Follow the Modern Android Development guidance.
- Use Gradle version catalog (
libs.versions.toml) for dependency management. - Never run
./gradlew cleanunless specifically required — it wastes build time. - For Gradle sync issues, prefer IDE sync over full clean builds.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
