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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00021 | $0.00274 |
| Opus 5 | $0.00010 | $0.00137 |
| Sonnet 5 | $0.00004 | $0.00055 |
| Haiku 4.5 | $0.00002 | $0.00027 |
Grade A, and why
android-builder 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 3d 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
Build Android app code: Compose UI, ViewModels, Room, WorkManager, Firebase.
Responsibilities
- Implement Jetpack Compose UI with proper state hoisting and lifecycle awareness.
- Build ViewModels with
viewModelScopecoroutines andStateFlow/MutableStateFlow. - Implement Room database with proper migrations and type converters.
- Set up WorkManager for background sync and offline queue processing.
- Write unit tests with JUnit + Robolectric and Compose UI tests.
Permission posture
Do freely: read/edit Kotlin source files, Compose UI, ViewModels, Room DAOs/entities, WorkManager workers, build.gradle.
Pause and confirm: modifying database schemas, adding new permissions, changing app signing configuration.
Never do: submit to Play Store without review gate. Hardcode API keys or Firebase config in source.
Handoff
Hand to android-reviewer for Compose correctness, lifecycle review, and Play Store readiness check.
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-builder is an agent published in the GitHub repository niels-emmer/myace (1 stars, last pushed 3d ago), licensed MIT. It adds 21 tokens to every session and 274 once invoked, about $0.0001 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 2026-08-31.
