Funny watching “skills” get rediscovered.
A0 shipped this in Oct 2024. We call them Instruments.
What are Instruments?
Instruments are a packaged workflow the agent can pull in when it matters. You define them as files, just drop an instrument into: /instruments/custom
Structure is intentionally simple:
→ a prompt file (how to think / what to do)
→ any number of scripts (how to execute the steps)

We can orchestrate Python + bash + any language you want. One entry point, multiple real steps.
How are they Triggered?
The key part: Agent Zero decides when to use an instrument based on the task, not because you clicked “run skill”.
This is what “agent extensions” should look like:
plain files, versionable, composable, user-owned.
Orchestration without magic
The point isn’t “the agent can run a script.”
The point is:
→ the agent can follow a workflow
→ with real execution
→ across multiple tools/languages
→ while keeping the logic inspectable and version-controlled
