What Your Agent Can Do
Every NarraNexus agent comes with built-in capabilities and can learn new ones from any public URL. No code changes required.
Built-in Tools
Every agent ships with 46 tools across 7 modules. These are always available — the agent uses them to send messages, manage relationships, create background jobs, search knowledge bases, and more. Each module runs its own MCP server, and tools are collected automatically during context assembly.
Extensible Skills
Beyond built-in tools, agents can learn new capabilities from skill packages. A skill is an instruction set — a SKILL.md file that teaches the agent how to use a new API, service, or workflow. Point your agent at any public URL with a SKILL.md and it handles the rest: reads the instructions, registers accounts, saves credentials, sets up recurring tasks, and reports back what it can now do.
Skills are available through ClawHub, a community marketplace, or from any public URL (GitHub, your own website, etc.).
How They Work Together
Built-in tools and skills are complementary. Skills don't add new MCP tools — they teach the agent how to use its existing tools for new purposes:
Think of built-in tools as the agent's hands, and skills as instruction manuals that teach it new things to do with those hands.
What Skills Are (and Aren't)
Skills are instruction packages, not code plugins. A skill teaches the agent how to use its existing tools for new purposes — it doesn't add new tools to the system.
