Chrome Extension Scope Generator
Plan a focused browser extension scope before building a package.
No Fundy Chrome extension package is released yet. This browser tool creates a planning draft only.
This tool runs in your browser, and inputs stay on your device until you choose to copy or download the result.
Generate Extension Scope
| Include | Workflow | Boundary |
|---|---|---|
| Open compressor, resizer, converter, or metadata tools. | No hidden uploads. | |
| Copy visible page colors after explicit activation. | No background scanning. | |
| Use filename and user context for local alt text drafting. | Not computer vision. | |
| Open product-photo and image prompt templates. | Does not call an image model. |
Planned Free Capabilities
| Workflow | Planned behavior | Related web tool |
|---|---|---|
| Image utility shortcuts | Open the compressor, resizer, converter, or metadata remover with the selected image context. | Image Compressor |
| Color sampling | Let the user sample visible page colors and copy HEX values after explicit activation. | Color Auditor |
| Alt text drafting | Use filename and user-provided context to draft local alt text. | Alt Text Helper |
| Prompt template handoff | Open product photo or image prompt templates for selected page context. | Product Prompt Studio |
Privacy Boundary
The extension should avoid broad background scraping, hidden uploads, or automatic page analysis. Every action should be user-triggered and local unless a future release explicitly documents a remote service.
The generated draft favors narrow Manifest V3 permissions. A real package still needs manual implementation, extension testing, store-policy review, and permission warning review.
Workflow Notes
Best for
- Team scoping meetings where design and engineering need a shared, versioned extension plan before writing code.
- Defining a privacy-safe Manifest V3 baseline for a Fundy-specific utility that opens tools, drafts text, or samples UI context only after user action.
- Preparing a handoff pack for implementation where permissions, boundaries, and expected behavior must be auditable before building or filing for store review.
- Comparing multiple scope variants quickly, for example no-host vs activeTab vs optional host flow, before committing architecture decisions.
Check before using it
- Confirm one explicit user trigger for every behavior, such as toolbar click, context menu action, or active tab activation.
- Decide which workflows are truly in scope now, and mark all others as out of scope for this plan to avoid hidden feature creep.
- Define host and data boundaries before changing defaults: which sites are needed, what user data stays local, and where explicit grants are shown.
- Ensure you have reviewed existing Chrome extension docs and your own governance rules before opening the draft for implementation.
Review the output
- Verify the output includes a manifest_version 3 draft, status marker, selected primaryAction, capability list, and implementationChecklist fields.
- Check that permissions match the selected host mode exactly and that no broad host access is enabled unintentionally.
- Validate the privacyBoundary list includes no hidden uploads, no background scanning, and explicit user-triggered action language.
- Scan implementationChecklist for required tests such as toolbar and context menu behavior, empty page handling, and Chrome permission warning review before moving to code.
Limits to keep in mind
- This tool only generates a planning draft; it does not build, test, publish, or package a real extension.
- It does not perform uploads, account sync, remote model inference, or any automatic server-side page analysis.
- Browser store approval, distribution packaging, signing, and policy compliance are separate steps outside this generator.
- The optional host permission example is a placeholder and should be replaced with exact domains and a real review flow during implementation.
Handoff
- Use Free EXIF Metadata Remover before publishing any source image so metadata safety is handled separately from scope design.
- Use Free Image Compressor next when output file size and format quality are the next quality gate.
- Use Free AI Alt Text Generator to prepare alt text wording strategy after drafting extension boundaries.
- Use Free AI Image Prompt Builder when prompt template handoff content needs structure before any external model use.
How to Use
- Set a specific extension name and confirm the primary action model first. Use toolbar action if users click a visible icon, use context menu only for explicit right click
- Select host access deliberately. Start with no host permissions for a pure local shortcut model, switch to activeTab only when the action must touch page content, and use optional
- Review each capability toggle and disable what is not needed. Keep image shortcuts, color sampling, alt text drafting, and prompt template handoff to the minimum set that
- Click generate to produce the draft JSON, then copy or download it. In the output, verify the status field, manifest permissions, implementation checklist, and privacy boundary
FAQ
Is Chrome Extension Scope Generator free?
Yes. It runs in the browser and does not require an account.
What does it do?
Generate a local Manifest V3 planning draft for a Chrome extension with explicit action scope, permissions, and privacy boundaries.
What should I use next?
Usually EXIF Metadata Remover is the next step when you want to create a local, privacy-clean copy of selected images before sharing or upload by removing embedded metadata while keeping the visual content intact.
Can I finish a useful task with this tool without creating an account?
Yes. The workflow stays fully in-browser and local. You can generate, copy, and download a scope draft immediately with no account required.
Does this upload any page content or browser data to a Fundy server?
No. The planner runs in your browser. Inputs remain on your device until you copy or download the output file.
What should I check before I trust the generated manifest draft?
Check the selected action mode, whether permissions are narrower than your real need, whether optional host grants are truly optional, and whether each capability is user-triggered with clear boundaries.
Can I use this result as a store-ready package?
No. It is a planning draft only. You still need implementation, manual testing in Chrome, and store policy review before release.
