What it does
Ha Android Review is an agent skill from home-assistant/android. Home Assistant Android code review guidance. Use when reviewing changes or a diff for correctness, style, and convention adherence, or checking security requirements.
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

When your agent uses it
- Reviewing changes
- A diff for correctness
- Convention adherence
- Checking security requirements
Example prompts
- “/ha-android-review”
What it can do on your machine
Read from SKILL.md and the folder at commit 9e658ce. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ha Android Review loads about 594 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 290 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

HA Android Review
Use this skill when reviewing Home Assistant Android changes. For finalizing your own change — format, tests, changelog, branch, and PR — use the ha-android-committing skill.
Review Checklist
Load the skill covering each dimension the change touches and review against its rules — the rules live in the skills, not here, so this list stays a router:
- Kotlin style: constants, strong types, immutability, visibility, KDoc —
ha-android-kotlin-style. - Coroutines and threading: scopes, dispatchers, shared state, blocking calls —
ha-android-concurrency. - Logging and errors: catch blocks,
CancellationException, sensitive data, FailFast —ha-android-logging-errors. - UI: Compose, HATheme, ViewState, navigation, widgets —
ha-android-ui. - Structure: modules, layers, ViewModels, repositories, server-version gating, DI, storage —
ha-android-architecture. - Tests: unit, Turbine, Robolectric, screenshot and interaction tests —
ha-android-testing.
One review point that has no other home: reuse before rewrite — check whether the logic already exists (pickers, url handling, shared utils) and extract shared code instead of duplicating it.
Engineering Values
- Mechanism over reminder: when the same review comment keeps coming back, encode it instead of repeating it — a custom lint rule in
:lint, a KTLint override in.editorconfig, aFailFastcheck, a module-wide test listener, or an update to these skills. A convention that relies on people remembering it will keep being violated. - Root cause before fix: a bug fix must state the actual cause and how to reproduce it. Don't patch symptoms; if the cause is external (platform, WebView, library), document the evidence and the repro steps rather than adding speculative workarounds.
Review Tone
Be kind and respectful. Give hints instead of orders, and use examples to explain issues.
Security
- GitHub Actions: use the most restrictive permissions — don't request write when read (or none) suffices.
- Never commit tokens or secrets; use GitHub Secrets for CI/CD.
- Use well-known, maintained libraries or stick to the Android SDK.
