# Plan a Chrome Accent Color Extension

Website recoloring requires coordinated color states, CSS overrides, and browser extension controls. This public guide outlines those requirements for an AI-assisted implementation.

## Capabilities

- Outlines a Manifest V3 extension concept using service workers and the Scripting API.
- Describes generating hover, active, border, and muted colors from one input color.
- Identifies early stylesheet injection and high-specificity selectors as the proposed theming approach.
- Lists per-domain settings, local persistence, and custom CSS as intended features.
- Describes a vanilla JavaScript, HTML, and CSS workflow without a bundler.
- Documents limitations involving framework build steps, shadow DOM, and protected Chrome pages.

## Use Cases

- Scope an extension prototype: Use the stated features to define an implementation plan for accent colors, popup controls, and per-domain preferences.
- Explore color state requirements: Review the proposed hover, active, border, and muted states before designing a consistent accent palette.
- Study extension architecture: Discuss the relationship between Manifest V3, content styling, local settings, and a no-build development workflow.

## Prompt Templates

### Summarize the guide

```
Summarize the extension concept in this guide. Separate documented features from implementation files that are not included.
```

### Define palette requirements

```
Using #ff5733 as the accent, propose hover, active, border, and muted color requirements. Do not claim the guide includes working color calculations.
```

### Plan per-domain controls

```
Plan a vanilla JavaScript Manifest V3 prototype with per-domain toggles and local persistence. Identify required files, permissions, and tests before generating code.
```

### Review implementation risks

```
Review this extension concept for permission scope, CSS conflicts, shadow DOM limitations, protected pages, and color contrast. Distinguish documented claims from unverified behavior.
```

## Limitations

- Only SKILL.md is included; extension source, scripts, templates, and assets are absent.
- The guide does not provide executable HSL calculations or CSS injection logic.
- Production readiness, Manifest V3 compliance, and universal website compatibility are not verified by this package.
- The guide excludes React or Vue build workflows and notes restrictions affecting shadow DOM and protected Chrome pages.

## Best Practices

- Treat this package as a planning guide and verify which implementation assets are available before starting development.
- Limit extension permissions to approved sites and review generated code before loading it into Chrome.
- Test color contrast, site controls, and styling conflicts across representative pages before wider use.

## Anti Patterns

- Assuming the guide includes a deployable extension or the advertised source package.
- Claiming universal website support or accessible contrast without testing a real implementation.
- Granting broad site access without evaluating whether narrower permissions meet the intended use.

## Security Audit

- Audited at: 2026-11-02T12:25:09.415\+00:00
- Summary: All six static findings are false positives: Markdown code spans and attribution links do not execute commands, transmit data, or perform reconnaissance. No evidence found of prompt injection or malicious intent in SKILL.md. This package contains only a descriptive guide, so advertised extension implementation and security claims cannot be verified.
