Payment guard middleware for AI agents. Use whenever any skill is about to initiate a payment. Runs a preflight check against the user's policy (payments enabled, per-transaction limit, monthly cap). Returns ALLOW, DENY, or CONFIRM_REQUIRED. Other payment-capable skills must call signet-preflight before proceeding and signet-record after a successful payment.

After testing dozens of developer-focused AI skills, these are the seven that have proven genuinely useful across different tech stacks and workflows β not just impressive demos, but tools that hold up under daily use.
MCP Skills vs Native Claude Tools: What's the Difference and When to Use Each
Claude comes with built-in capabilities, but MCP skills extend it in ways the base model can't. Here's a clear breakdown of what each type of tool is good for, with real examples of when to reach for a skill versus relying on Claude's native abilities.
Signet Guardian extends your AI assistant with the ability to payment guard middleware for AI agents. Use whenever any skill is about to initiate a payment. Runs a preflight check against the user's policy (payments enabled, per-transaction limit, monthly cap). Returns ALLOW, DENY, or CONFIRM_REQUIRED. Other payment-capable skills must call signet-preflight before proceeding and signet-record after a successful payment. Rather than leaving your conversation to handle this manually, you can ask your Claude agent directly β and it will take care of the task end-to-end, using Signet Guardian as its underlying capability.
Signet Guardian works across Claude, Cursor, OpenClaw through the Model Context Protocol (MCP) β an open standard that lets AI clients share tools and skills without lock-in. Because MCP is platform-agnostic by design, you install Signet Guardian once and it becomes available across all your AI clients. Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.
To install Signet Guardian, copy the skill folder to `~/.claude/skills/signet-guardian/` for use across all your projects, or `.claude/skills/signet-guardian/` for a single project. Restart Claude and the skill is immediately active β invoke it with `/signet-guardian` or just describe your goal and the AI will pick it up automatically.
Signet Guardian has 767 installs and is part of the growing Product Manager skill ecosystem on DiscoverAISkills. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
Place the skill folder at ~/.claude/skills/signet-guardian/ for personal use (all projects), or .claude/skills/signet-guardian/ for project-specific use. Restart your AI client, then invoke with /signet-guardian or let the AI discover it automatically.
Signet Guardian supports Claude, Cursor, OpenClaw. It integrates seamlessly with these AI platforms to extend their capabilities.
