# Plan a Chrome Clipboard Cleaning Extension

Copied text can contain tracking parameters and invisible Unicode characters. This public guide outlines a Manifest V3 cleaning extension, but implementation source is not included.

## Install

## Capabilities

- Describes a copy-event cleaning workflow for a Manifest V3 Chrome extension.
- Identifies UTM parameters, fbclid, and gclid as URL cleaning targets.
- Lists zero-width characters and Unicode directional marks as text cleaning targets.
- Outlines separate Unicode stripping and URL parameter filtering stages.
- Describes popup and settings controls for selecting cleaning categories.
- Summarizes a no-build development approach using vanilla JavaScript, HTML, and CSS.

## Use Cases

- Define an extension prototype: Translate the described cleaning pipeline into implementation requirements and acceptance criteria without assuming source files are included.
- Evaluate clipboard privacy requirements: Review the proposed tracking parameters and Unicode targets before selecting cleaning rules for organizational use.
- Study no-build extension concepts: Use the feature overview to discuss Manifest V3 components, settings, and browser testing with a mentor or coding assistant.

## Prompt Templates

### Understand the guide

```
Summarize the clipboard cleaning workflow described in this guide. Separate documented features from implementation files that are not included.
```

### Define cleaning requirements

```
Draft requirements for removing utm_*, fbclid, and gclid while preserving other URL parameters. Include Unicode cleanup settings and meaningful text preservation.
```

### Plan a new implementation

```
Plan a new vanilla JavaScript Manifest V3 implementation from this overview. Identify copy handling, cleaning stages, settings, permissions, and missing implementation details.
```

### Review privacy and edge cases

```
Create a privacy review and test matrix for this proposed extension. Cover multilingual text, signed URLs, restricted pages, permissions, and clipboard data retention.
```

## Limitations

- Only SKILL.md is included; extension source, scripts, templates, and deployment assets are absent.
- Claims of production readiness and testing cannot be verified from this documentation.
- The described extension targets Chrome copying workflows, not system dialogs or applications outside the browser.
- Obfuscated tracking URLs require additional handling, and the guide does not support React or Vue build workflows.

## Best Practices

- Treat this package as a requirements guide and verify which implementation assets are actually available.
- Test URL changes and Unicode cleanup against signed links and multilingual text before enabling broad filtering.
- Use minimal browser permissions and keep copied text local when implementing the described workflow.

## Anti Patterns

- Assuming the guide installs a working extension or includes the source files mentioned in its examples.
- Removing every query parameter or invisible character without checking functional and linguistic effects.
- Claiming production readiness or store approval without reviewing implementation, permissions, and browser test results.

## Security Audit

- Audited at: 2026-11-02T12:44:00.376\+00:00
- Summary: All four static findings are false positives: the URLs are promotional references, and the footer contains no system reconnaissance instructions. No evidence found of executable payloads, credential collection, data exfiltration, or prompt injection in SKILL.md. The package contains only a public guide, despite broader claims about included extension source.
