What it does

Nekocap Redux Feature is an agent skill from nopol10/nekocap. Use when adding or modifying a Redux feature folder in the nekocap frontend — creating slices, writing sagas, defining selectors, changing persisted state shape, or touching redux-logger / reduxed-chrome-storage wiring.

Its SKILL.md is about 940 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 Frontend & Design, covering State management. It works with Redux. The repository describes itself as: Browser extension for creating & uploading community captions for YouTube, niconico and other video sharing sites. The licence is GPL-3.0.

When your agent uses it

  • Modifying a Redux feature folder in the nekocap frontend — creating slices
  • Defining selectors
  • Changing persisted state shape
  • Touching redux-logger / reduxed-chrome-storage wiring

Example prompts

  • “/nekocap-redux-feature”

What it can do on your machine

Read from SKILL.md and the folder at commit cf47362. 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 (its code samples are typescript).

    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

Nekocap Redux Feature loads about 939 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 343 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~939

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.

description
Use when adding or modifying a Redux feature folder in the nekocap frontend — creating slices, writing sagas, defining selectors, changing persisted state shape, or touching redux-logger / reduxed-chrome-storage wiring.

This skill covers the Redux Toolkit + redux-saga conventions used in src/common/feature/<name>/ and the rules around state that gets persisted to chrome.storage.local.

Canonical feature-folder shape

Mirror src/common/feature/login/ when adding a new feature. The expected files, in this order:

src/common/feature/<name>/
  action-types.ts    String constants for action types
  actions.ts         createAction / createSignal definitions
  reducers.ts        createReducer slice
  sagas.ts           takeLatest/takeEvery wired to actions
  selectors.ts       Reselect-style selectors
  types.ts           Local state shape + payload types
  utils.ts           (optional) feature-local helpers
  containers/        (optional) connected components
  api.ts             (optional) RTK Query endpoints — see nekocap-data-fetching skill

Don't invent a different layout. Don't merge files. Don't put the slice inline in a component.

Always wrap sagas in safe()

src/common/redux-utils.ts exports safe():

ts
import { takeLatest } from "redux-saga/effects";
import { safe } from "@/common/redux-utils";

function* mySaga(action) { /* ... */ }
export default [takeLatest(myAction.REQUEST, safe(mySaga))];

An unwrapped saga that throws kills the entire saga middleware silently. safe() catches and logs via console.error. Every takeLatest / takeEvery registration goes through it.

Selectors

Define selectors in selectors.ts with descriptive names (loginSelector, userDataSelector, searchResultsSelector). Import them by name in components:

ts
const user = useSelector(userDataSelector);

Do not reach into state.someSlice.x directly in components or other sagas — that creates an untracked coupling that breaks silently when slice shape changes.

Persisted state — handle with care

Redux state is persisted to chrome.storage.local via reduxed-chrome-storage. Store wiring is in src/common/store/store.tsx.

Changing the shape of a persisted slice is a breaking change. Existing users have old state in their browser storage. When you rename a field or change a type:

  • Either add a migration in the persist config, or
  • Accept that affected users will see their state reset (and confirm that's acceptable for the slice in question).

Some slices are intentionally cleared on extension startup (transient UI state). Before moving startup-clear logic, read src/common/store/store.tsx to understand which slices are expected to survive a reload and which aren't.

redux-logger gate

redux-logger is enabled in dev only:

ts
process.env.PRODUCTION ? undefined : logger

Don't enable it in production. Don't replace the gate with a different env check.

When you change X, also check Y

If you change…Also verify…
Persisted slice shapeMigration added or user-state-reset accepted
Saga error handlingStill wrapped in safe()
Action typesAll takeLatest / takeEvery registrations still match
SelectorsNo component is reading state.x directly anymore

Anti-patterns specific to Redux features

  • Don't write a saga without safe().
  • Don't invent a new feature-folder layout. Mirror src/common/feature/login/.
  • Don't call Redux actions directly from a saga — use put() from redux-saga/effects.
  • Don't access slice state directly in components. Use a selector.
  • Don't change persisted shape without a migration plan.
