Beautiful README badges, inspired by shields.io and styled like shadcn/ui.

No outside reports on file

This tool's main risks depend on how it handles user input for badge customization and whether it makes external requests—always validate inputs strictly and monitor network activity.

Risks to watch for

Badge generation from untrusted input: If the agent accepts user-provided badge text or parameters without validation, malicious input could be embedded in the generated image or cause unexpected behavior
Image hosting or external requests: Badge generation tools sometimes make requests to external servers to render or store images, potentially leaking project metadata
Dependency vulnerabilities: Like any npm package, it could depend on libraries with security issues that affect systems using this skill
Code injection through styling: Malicious CSS or SVG parameters could be injected if the tool doesn't properly sanitize style or design inputs
File system access: The skill might write generated badges to disk in ways that could overwrite or expose sensitive files if paths aren't carefully controlled

How to lower the risk

Least-privilege permissions

Run only with read access to project files it documents
Restrict write access to a single output directory for generated badges

Network isolation

Disable outbound network requests unless badge rendering absolutely requires them
Use allowlist rules if external calls are necessary

Monitoring

Log all badge generation requests, especially custom text or parameters
Alert on unusual file writes or new dependencies being pulled

Red flags to watch for

Requests to generate badges with very long or unusual text strings
Attempts to specify file paths outside the badge output directory
Unexpected network calls to unfamiliar domains during badge creation
