A code-review command that checks code in five areas: correctness, readability, architecture, security, and performance.

Use it to review application changes, especially Kotlin code with UI, domain, and data layers, database queries, permissions, logging, and background work.

It groups review findings by type, making problems easier to locate and discuss. The checks include common concerns such as error states, unsafe input, secrets, slow queries, and unclear code.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods

npx agentmods add commands/guillemroca/agent-skills-android/review

Clone the repo

git clone --depth 1 https://github.com/GuillemRoca/agent-skills-android

Made for: Claude Code.

Or install agent-skills-android, the plugin that ships this one along with the rest of its 29 skills, 7 commands, 3 agents, 1 hook.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 386 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. Scan, not verified.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00386
Opus 5	$0.00000	$0.00193
Sonnet 5	$0.00000	$0.00077
Haiku 4.5	$0.00000	$0.00039

Measured 6d ago against content hash 025084c41003, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-06, from the pricing page.

Security

Grade A, and why

review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/review — Code Review

Review code across five axes with categorized findings.

Instructions

Load and follow these skills:

code-review-and-quality from skills/code-review-and-quality/SKILL.md
security-and-hardening from skills/security-and-hardening/SKILL.md
performance-optimization from skills/performance-optimization/SKILL.md

Five-Axis Review

1. Correctness

All UI states handled? (loading, success, error, empty)
Nulls handled safely? (no !!, proper safe calls)
Coroutines structured correctly? (scope, cancellation)
Room queries match schema? Migrations correct?

2. Readability

Kotlin idioms used? (when, sealed classes, extension functions)
Clear naming? Functions < 40 lines?
Consistent with existing codebase patterns?

3. Architecture

Layer boundaries respected? (UI → Domain → Data)
StateFlow exposed (not MutableStateFlow)?
Constructor injection (not field injection)?
No business logic in Composables?

4. Security

No hardcoded secrets?
Input validated at boundaries?
Exported components permission-protected?
No sensitive data in logs?

5. Performance

No N+1 queries?
Heavy work off main thread?
Compose recompositions optimized?
Large datasets paginated?

Finding Categories

Category	Action
Critical	Must fix before merge
Important	Should fix before merge
Suggestion	Optional improvement
Nit	Formatting preference
FYI	Context, no action needed

Verification

Run before approving:

./gradlew test
./gradlew assembleDebug
./gradlew lint

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

review is a command published in the GitHub repository GuillemRoca/agent-skills-android (2 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 386 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
