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.

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 | $0.00080 | $0.00313 |
| Opus 5 | $0.00040 | $0.00156 |
| Sonnet 5 | $0.00016 | $0.00063 |
| Haiku 4.5 | $0.00008 | $0.00031 |
Grade A, and why
aosp-runtime 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 5d 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
AOSP Part V — Runtime
The Android Runtime (ART) and the binary translation layer that lets arm-only native code run on x86_64 devices.
Chapters in this Part
18-art-runtime.md— dex2oat, AOT/JIT, baseline profiles, GC (concurrent copying), oat/vdex/odex files, class loaders, JNI bridge19-native-bridge.md— cross-architecture native code execution, Houdini → Berberis, intercepting libc/JNI calls, performance trade-offs
When to load which chapter

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.

aosp-runtime is a skill published in the GitHub repository aospbooks/aosp-internal-book (130 stars, last pushed 6d ago), licensed Apache-2.0. It adds 80 tokens to every session and 313 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings.
