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.

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 | $0.00052 | $0.00389 |
| Opus 5 | $0.00026 | $0.00195 |
| Sonnet 5 | $0.00010 | $0.00078 |
| Haiku 4.5 | $0.00005 | $0.00039 |
Grade A, and why
android-performance 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 8d 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
Android Performance Standards
Priority: P1 (HIGH)
1. Accelerate Startup
- Generate Baseline Profiles for all production apps — pre-compiles critical paths (30-40% startup improvement).
- Defer heavy SDK init using
App Startupor lazy Singletons. Never blockApplication.onCreate.
See baseline & startup for lazy initialization patterns.
2. Eliminate UI Jank
- Use Layout Inspector to find unnecessary recompositions.
- Load images with Coil/Glide using proper caching and resizing (
.crossfade()). LazyColumnmust usekeyand stable item classes.
See baseline & startup for LazyColumn optimization.
3. Avoid Layout Bottlenecks
- Replace nested weights with
ConstraintLayout(Views) orRow/ColumnwithModifier.weight(Compose). - Never hold Activity context in Singletons — use Application context to prevent memory leaks.
Anti-Patterns
- No Nested Weights: Use ConstraintLayout (Views) or Row/Column (Compose) instead.
- No Activity Context in Singletons: Use Application context to prevent memory leaks.

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

android-performance is a skill published in the GitHub repository HoangNguyen0403/agent-skills-standard (565 stars, last pushed 2d ago), licensed MIT. It adds 52 tokens to every session and 389 once invoked, about $0.0003 per session on Opus 5. 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 2026-09-03.
