What it does
Aosp Appendices is an agent skill from aospbooks/aosp-internal-book. AOSP Internals — Appendices. Use when looking up a key file path (per-chapter table of the most important AOSP source files: build, init, kernel, HAL, framework services, system apps, infrastructure) or the meaning of an AOSP-specific acronym/term (Treble, VINTF, GKI, APEX, AIDL, HIDL, etc.), why Kotlin is absent from the public API, or what changed from Android 16 to Android 17. Reference material — load when you need a concrete path, a definition, or a changelog rather than narrative explanation.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering Android development and Changelog and release notes. It works with Android and Kotlin. The repository describes itself as: The book introduces the internal of AOSP. The licence is Apache-2.0.

Example prompts
- “/aosp-appendices”
What it can do on your machine
Read from SKILL.md and the folder at commit fc0b48b. 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
Aosp Appendices loads about 444 tokens when it runs. Until then it costs about 130 tokens; SKILL.md has 143 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.
