jetpack-compose-patternsApplies practical Jetpack Compose patterns to Android UI code: state hoisting, one-way data flow, side effects, modifiers, theming and testable composables.
The quick start tells the agent to find the smallest relevant Compose surface, whether a screen, route, state holder, component, modifier, preview or test, and to keep the project's existing architecture, Material version, theme, navigation, dependency injection and state conventions. Route-level, stateful composables are separated from stateless UI composables when that helps testing and reuse, state flows down and events flow up, and minimal behavior-preserving changes win over broad rewrites.
The workflow first identifies whether code is a screen route, a reusable component, a design-system primitive or a one-off layout, and where its state comes from. Route composables handle ViewModel collection, navigation callbacks, permission launchers and snackbars, while content composables render immutable state and callbacks such as `onRetry`. State is hoisted to the lowest common owner, with `rememberSaveable` for user input that should survive recreation. Effect APIs like `LaunchedEffect` and `DisposableEffect` are used only when their lifecycle matches, with stable keys.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit cd22acf. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Jetpack Compose Patterns loads about 1.7k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 866 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.
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.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 866 words (~1,697 tokens).

Jetpack Compose Patterns fits situations like: building a new Compose screen or reusable component; refactoring composables that mix state handling with rendering; reviewing Compose code for side-effect and state-ownership mistakes; explaining state hoisting and unidirectional data flow in a Compose codebase.
Run `npx skills add ModinMobileSTS/SlayTheAmethystModded --skill jetpack-compose-patterns -a claude-code`. Or copy the skill folder (.opencode/skills/jetpack-compose-patterns in ModinMobileSTS/SlayTheAmethystModded) into .claude/skills/jetpack-compose-patterns in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ModinMobileSTS/SlayTheAmethystModded --skill jetpack-compose-patterns -a codex`. Or copy the skill folder (.opencode/skills/jetpack-compose-patterns in ModinMobileSTS/SlayTheAmethystModded) into .agents/skills/jetpack-compose-patterns in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ModinMobileSTS/SlayTheAmethystModded --skill jetpack-compose-patterns -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/jetpack-compose-patterns, .gemini/skills/jetpack-compose-patterns, .github/skills/jetpack-compose-patterns and .opencode/skills/jetpack-compose-patterns in your project.
SKILL.md names no scripts, command-line tools or credentials: Jetpack Compose Patterns is instructions for the agent only. Our summary lists: An Android project that uses Jetpack Compose.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Jetpack Compose Patterns has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 1.7k tokens (SKILL.md is roughly 6.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
