Agents outside Anthropic that support Agent Skills
Third-party coding agents and assistants that have adopted the Agent Skills format, making a skill you write portable beyond Claude.
Independent project
This is a community project. It is not built, reviewed or supported by Anthropic, and inclusion in this directory is not an endorsement. Read the source before granting it access to your accounts, files or credentials.
Agent Skills were released as an open standard, and a substantial number of agents outside Anthropic have implemented the format. The practical consequence: a skill is a portable artefact rather than a Claude configuration file.

What this means in practice
If your team maintains skills for internal processes — how you write tickets, how you structure migrations, your review checklist — those travel. Adopting a different agent does not mean rewriting them.
That is a genuinely unusual property in this space, and it is worth weighing when deciding whether to encode a workflow as a skill rather than as tool-specific configuration.
What this listing is not
Not an endorsement, not a comparison, and not a claim about how completely each product implements the format. Implementation depth varies, and this reference has not tested any of them.
Security notes
These are independent products, not Anthropic ones. Listing here reflects that they implement the Agent Skills format, not that this reference has evaluated their security, data handling or quality.
