What it does

Android Development is an agent skill from CoWork-OS/CoWork-OS. Android/Kotlin development: Jetpack Compose, Room database, Gradle builds, emulator management, and Play Store submission.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/full-guidance.md`).

It sits in Mobile, covering Android development. It works with Gradle, Kotlin, Android and Jetpack Compose. The repository describes itself as: Local-first personal agentic OS and everything app for coding, knowledge work, web design, automations, and artifacts. The licence is MIT.

When your agent uses it

  • Tasks that involve Android development

Example prompts

  • “/android-development”

What it can do on your machine

Read from SKILL.md and the folder at commit 3691bae. 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

    Ships 1 file in scripts/, which the agent can run.

    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

Android Development loads about 459 tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 36 tokens; SKILL.md has 201 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~459
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.3k

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); the scripts in this folder are not scanned.

Purpose

Android/Kotlin development: Jetpack Compose, Room database, Gradle builds, emulator management, and Play Store submission.

Routing

  • Use when: Use when the user asks about Android development, Kotlin, Jetpack Compose, Room database, Gradle builds, ADB, Android emulator, Play Store submission, or Android-specific architecture.
  • Do not use when: Do not use for iOS development (use ios-development), React Native (use the mobile pack), or general mobile CI/CD (use the mobile pack's build-pipeline skill).
  • Outputs: Kotlin code, Compose UI, Gradle configurations, and Android development guidance.
  • Success criteria: Returns valid Kotlin/Compose code or Gradle/ADB commands.

Trigger Examples

Positive
  • Use the android-development skill for this request.
  • Help me with android development.
  • Use when the user asks about Android development, Kotlin, Jetpack Compose, Room database, Gradle builds, ADB, Android emulator, Play Store submission, or Android-specific architecture.
  • Android Development: provide an actionable result.
Negative
  • Do not use for iOS development (use ios-development), React Native (use the mobile pack), or general mobile CI/CD (use the mobile pack's build-pipeline skill).
  • Do not use android-development for unrelated requests.
  • This request is outside android development scope.
  • This is conceptual discussion only; no tool workflow is needed.

Runtime Prompt

  • Current runtime prompt length: 903 characters.
  • Runtime prompt is defined directly in ../android-development.json.
