Agent Plugins Specification v1.0.0 — A minimal standard for packaging agent extensions into distributable plugins
No outside reports on file
This specification itself is a neutral standard, but plugins built to it only as safe as their implementation and the source you download them from—trust the publisher, verify the code, and use version-locking to prevent surprise updates.
Based on public adoption and transparency signals as of Oct 22, 2026. Our opinion, not a code audit or security guarantee.

About Agent Plugins Spec
This is a specification (a set of rules and standards) that describes how to package AI agent extensions into plugins. It defines the format and structure that tools and skills should follow so they can work as plug-and-play additions to AI agents.
Who it’s for
Developers building AI agent platforms or creating reusable agent extensions. Teams that want a common standard for how agent plugins should be structured and shared.
Alternatives
- OpenAI Plugins standard — predecessor specification for plugin formats. - MCP (Model Context Protocol) — Anthropic's standard for connecting AI models to tools and data. - LangChain tools/agents — framework-specific extension system with tooling and validation. - Zapier/IFTTT integrations — non-AI-focused but similar plugin/extension marketplaces with review processes.
Setup
Check these steps against the project’s own instructions before running anything.
This is a specification document, not a tool to install. Follow the project's README on GitHub to learn the standard and apply it when creating or using agent plugins.

Security reports

Risks to watch for
- No direct access control: The spec itself doesn't enforce permissions, so plugins built to it could access any data or APIs an agent has permission to reach. - Execution trust required: Agents using plugins built to this spec must trust the plugin code, which could be modified after distribution. - No built-in validation: Without additional tooling, it's hard to verify that a plugin actually follows the spec or contains hidden malicious behavior. - Data leakage through plugins: A plugin could be designed to quietly log or transmit the agent's outputs to external servers. - Spec interpretation gaps: Ambiguous parts of a specification can lead to implementations with security holes.
How to lower the risk
Least-privilege permissions
- Only grant agent plugins access to APIs and data they actually need.
- Use API key scoping and role-based access to limit plugin capabilities.
Network isolation
- Run plugin code in sandboxed environments when possible.
- Monitor and restrict outbound network connections from plugins.
Monitoring
- Log all plugin installations, updates, and executions.
- Watch for unexpected network calls or data access patterns.
Red flags to watch for
- Plugins from unknown or unverified sources; check GitHub stars, maintenance status, and community reviews.
- Sudden updates with large code changes or new network requests; review diffs before upgrading.
- Plugins asking for overly broad permissions or API access they don't obviously need.
