At a glance
Guides Jetpack Compose and Compose Multiplatform work across Android, Desktop, iOS and web, plus Android TV, Material 3 motion, paging, navigation and design-to-code.
- Works in 5 steps: Understand the request → Analyze the design (if visual reference… → Consult the right reference → …
- Writing or debugging Jetpack Compose screens and state handling
- SKILL.md covers When this skill applies, Quick Routing, Review Mode and Workflow, plus 1 more section
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
The skill activates on Compose API mentions (state, side effects, navigation, theming, lazy lists, modifiers, recomposition), Compose Multiplatform terms such as `commonMain`, `expect` and `actual`, resources and iOS or web entry points, Android TV topics like D-pad focus and carousels, Paging 3, atomic design systems and design-to-code requests. Casual phrasing such as a slow Compose screen or broken recomposition also counts.
Review Mode starts on GitHub PR URLs and review phrases, and Compose projects are detected automatically when a session starts. The guidance is backed by references to AndroidX and Compose Multiplatform source, with files on accessibility, animation, composition locals, deprecated patterns, modifiers, navigation, paging, performance and multiplatform. It now ships as a plugin, and copies placed by hand in `~/.claude/skills/` are no longer updated.
When your agent uses it
- Writing or debugging Jetpack Compose screens and state handling
- Sharing UI across Android, desktop, iOS and web with Compose Multiplatform
- Reviewing a pull request that changes Compose code
- Building an Android TV interface or turning a design into Compose
Example prompts
- “My Compose list screen is slow and recomposes too often, so find out why.”
- “Review this PR for Compose mistakes and deprecated patterns.”
- “Move our shared screens into commonMain and handle the iOS entry point with expect and actual.”
Requirements
- A Jetpack Compose or Compose Multiplatform project
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Understand the request
- Analyze the design (if visual reference provided)
- Consult the right reference
- Apply and verify
- Cite the source
What it can do on your machine
Read from SKILL.md and the folder at commit 954ef54. 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
Jetpack Compose Expert loads about 4.8k tokens when it runs, and up to ~693k if it reads all its reference files. Until then it costs about 209 tokens; SKILL.md has 1,597 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,597 words (~4,848 tokens).
“The frontmatter description: is intentionally short to satisfy Codex / Copilot CLI's 1024-character cap on that field (see issue #12). The full trigger surface lives here so it stays available to Claude after the skill loads.”
