How does ThumbGate protect my environment during agent execution?

ThumbGate acts as a security firewall that intercepts tool calls to detect sensitive credentials (secrets) and prevent the agent from repeating previously documented mistakes or 'lesson failures' before the code execution occurs.

Which AI agents and IDEs are compatible with this skill?

This skill is provided in the SKILL.md format, making it compatible with any AI agent that supports open skill standards, including Claude Code, Cursor, Codex, and GitHub Copilot.

What exactly is included in this download versus the ThumbGate Pro subscription?

This purchase includes the SKILL.md configuration file optimized for version 1.37.2 of the public ThumbGate package; it does not include a subscription to the hosted ThumbGate Pro dashboard or shared history.

How do I install this skill into my existing AI agent workflow?

Installation is straightforward: you add the SKILL.md file to your agent's project directory or skill library, ensuring your environment has access to the thumbgate v1.37.2 package.

Can the agent bypass a security warning if it thinks the tool call is necessary?

ThumbGate takes a 'deny-by-default' approach where any detected secret or repeat failure results in a hard block, meaning the agent cannot proceed even if it issues a warning.

About this skill

ThumbGate checks a tool call before it runs. A detected secret is a deny. A repeated lesson failure is a deny. A warning is not permission to continue.

The zip is a SKILL.md for Claude Code, Cursor, Codex, Copilot, and any agent that reads the open skill format. It uses the public package thumbgate at version 1.37.2. Hosted ThumbGate Pro, the shared lesson history and dashboard, is a separate subscription and is not this file.

How to install

Works the same in every agent - Claude, Cursor, Codex, Copilot and 20+ more.
