Security Policy

What this repository contains

Plugins, skills, and hooks for Claude Code. No customer data. No credentials. No secrets. Skills describe workflows and call MCP-connected tools (Salesforce, Slack, Gong, etc.) at runtime using credentials that live on the installing user's machine.

What this repository does NOT do

  • Ship credentials, tokens, or API keys
  • Store customer data
  • Phone home to any external service
  • Execute network calls on its own — only the MCP servers the user has authorized

Security architecture for installers

When a portfolio company installs a plugin from this marketplace:

  1. Code runs locally. Plugin code executes inside Claude Code on the user's machine. No cloud middleware.
  2. Tool access is user-scoped. Plugins only access tools the user has connected via MCP / OAuth on their own machine.
  3. Hooks are auditable. Every hook is a shell script in <plugin>/hooks/*.sh. Read them before installing.
  4. Cache model. Plugins are copied into ~/.claude/plugins/cache/ on install — what you install is what runs. Edits to source require an explicit /plugin update to take effect.
  5. No auto-update unless enabled. Auto-update can be toggled per marketplace in /plugin settings.

Reporting a vulnerability

If you find a security issue:

  1. Do NOT open a public GitHub issue.
  2. Email the maintainer privately (contact via Radian Capital).
  3. Include: affected plugin/skill, reproduction steps, and severity assessment.

You should expect an acknowledgment within 5 business days.

What we'll fix urgently

  • Hooks that escape their intended scope (e.g., reading files outside the plugin folder when they shouldn't)
  • Skills that leak credentials in their outputs
  • Hooks that fail-open in dangerous ways (e.g., verify-connectors returning continue when it should block)
  • Any path that writes data to a third party not explicitly authorized by the user

What we won't treat as a vulnerability

  • Skills that produce wrong recommendations (file as a bug, not a security issue)
  • Workflows that depend on connectors the user hasn't installed
  • Performance issues
  • Compatibility with non-Claude-Code harnesses
