# Agent Instructions

## Project

Opera Cache Cleaner is an Opera-compatible Chromium extension that clears only the browser cache for a selected time range and can optionally schedule repeated cache cleanup.

## Repository Rules

- Derive the repository owner and repository name from the target repository remote or CI repository context. Never reuse the owner from the repository kit remote.
- Preserve the plain Manifest V3 extension structure. Do not add a framework unless the user explicitly asks for it.
- Keep runtime code in `background.js` and `popup/`.
- Keep permissions minimal. The extension currently uses only `browsingData`, `storage`, and `alarms`.
- Do not add host permissions, network calls, cookie/history access, or broad browser permissions without documenting the reason.
- Do not create a release unless the user explicitly asks for one.
- Keep `.codex/project.md` aligned when commands, artifact paths, or release rules change.

## Commands

Use these commands from this extension directory:

```bash
node --check background.js
node --check popup/popup.js
mkdir -p dist && zip -r dist/opera-cache-cleaner-extension.zip manifest.json background.js popup icons -x "*.DS_Store"
```

There is no package manager, dependency install, lint, or dependency audit command for the current project.

## Artifacts

Expected release artifact from this extension directory:

```text
dist/opera-cache-cleaner-extension.zip
```

## Finish Checklist

- `git diff --check` passes when the project is inside a Git repository.
- `node --check background.js` passes.
- `node --check popup/popup.js` passes.
- Release documentation is updated when release behavior changes.
