Anthropic Skills collects Claude skill examples, the Agent Skills specification, and a starter template for document, development, enterprise, communication, and creative tasks. The repository can be registered as a Claude Code plugin marketplace, and its example skills can also be used through Claude.ai or the API. A custom skill is a directory containing a SKILL.md file with YAML frontmatter and instructions. Most examples use Apache 2.0, while the document-creation skills are source-available rather than open source.

awesome-claude-skills curates Claude skills, resources, and tools for document work, development, data, communication, media, project collaboration, and security, with guidance for creating custom skills. It also highlights the connect-apps plugin, which uses Composio to connect Claude to more than 500 apps for actions such as email, issues, and Slack posts. That connector needs a Composio API key, and listed projects have their own setup and licenses.

Mercury Skills collects 132 SKILL.md playbooks across 23 categories in a searchable registry with detail pages, trending rankings, and local bookmarks. Skills can be installed through the Mercury CLI with version pinning and rollback safeguards, or copied directly into an agent’s skill directory. The same format is intended for Mercury, Claude Code, Codex, OpenClaw, Hermes, Cursor, and Gemini CLI, while public JSON feeds let other tools consume the catalog.

Venice Skills packages the Venice API into separate, on-demand Agent Skills for authentication, chat, Responses, embeddings, image generation, image editing, and other surface areas. Each folder contains a `SKILL.md` that an agent runtime can load when the corresponding endpoint is needed, and the catalog is maintained alongside the API specification. You can install the full `skills` directory or only selected folders into Claude Code, Codex, Cursor, Hermes, and compatible hosts. This is instruction material for agents, not a standalone Venice client.
