What it does
Compose State And Effects is an agent skill from chrisbanes/skills. Use when writing or reviewing Jetpack Compose state ownership, remember state, state hoisting, screen state holders, LaunchedEffect, DisposableEffect, SideEffect, Flow collection, navigation, snackbar, analytics, or focus requests.
Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/local-state.md`, `references/side-effects.md` and `references/state-hoisting.md`).
It sits in Mobile, covering Android development. It works with Jetpack Compose. The repository describes itself as: Skills for Kotlin, Jetpack Compose, and Android development. The licence is Apache-2.0.

- Reviewing Jetpack Compose state ownership
- Screen state holders
- DisposableEffect
- Flow collection
Example prompts

Read from SKILL.md and the folder at commit 00bda52. 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
Compose State And Effects loads about 988 tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 482 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.

Compose state and effects
Core principle
Give every piece of UI state one lowest responsible owner, then run imperative work through the effect whose lifecycle follows that owner. Composition renders; state and effects make rendering change safely.
A screen-ownership review is incomplete until it names the plain, previewable content composable that receives immutable state and event callbacks separately from app wiring and composition-owned runtime objects.
Procedure
- Establish the requested scope and visible behavioral requirements. Treat an ownership change as a finding only when code or task evidence shows a lifecycle, testability, business, or coordination need.
- Inventory mutable UI state, app state, event streams, app dependencies, and imperative work in the affected screen or component.
- Place each state value at its lowest necessary owner: local UI state, hoisted state, a plain UI state holder, or a screen state holder.
- For a screen boundary, keep durable data and intents in the wiring owner,
Compose runtime objects in composition or a plain UI state holder, and
rendering in a previewable content composable that takes immutable state
and callbacks. Read State hoisting for the
implementation shape; naming only state and intents is not that boundary.
Keep this content callable with sample state and callbacks; an
@Previewwrapper is optional and is not required for the state-driven boundary. Before adding it, confirm the module declares its tooling; do not assume Compose runtime or UI dependencies provide it. Respect the task's file scope: do not add tooling or change build files unless authorized. If Preview tooling is needed but unavailable within scope, omit the wrapper and report the setup gap. - Choose an effect API whose lifecycle matches the work, and key it by the semantic input that should restart or dispose it.
- Load the focused reference for every material concern below. Do not use a reference merely because its topic is adjacent.
- Route frame-rate reads, cross-phase back-writing, and
@ReadOnlyComposablecontracts to Compose performance. For that contract, distinguish a read of snapshotState.valuefrom an operation that changes the composer; the state read alone is not a violation. - Before responding to a screen-ownership review, verify all three screen seams in step 4 when visible code needs them.
- Finish when every state value has one owner, every effect has a justified lifecycle and key, and the UI can be previewed and tested without app dependencies. For review-only work, report no change when no evidence-backed issue remains; do not invent product requirements.
