Skill Instructions

This skill helps an agent write Python code with the generated Ax package axllm. Use the generated package API, examples, and manifests; do not import TypeScript-only APIs unless you are editing the TypeScript package.

When To Use

Build a structured generation program from a signature.
Attach typed tools or MCP-derived tools to a generation call.
Use package examples for no-key scripted clients and provider-api calls.

Package Facts

Language: Python.
Package: axllm.
Package API docs: API.md and axir-api.json.
Capability manifest: axir-capabilities.json.
Runnable examples: examples/.
Real network support: yes.
Scripted no-key transport support: yes.
Runtime profiles: javascript-quickjs, python-pyodide.

Core Pattern

Python

from axllm import ax

program = ax("question:string -> answer:string")
out = program.forward(llm, {"question": "What is Ax?"})

Relevant API Surface

AxGen: ax, AxGen
Tools: fn, Tool
MCP: AxMCPClient, AxMCPStreamableHTTPTransport, AxMCPStdioTransport

Guardrails

Start from package examples for exact native syntax before inventing a new call shape.
Use provider-api examples only when the user explicitly has provider credentials available.
Use no-key examples for deterministic local checks and provider request mapping.
Treat AxIR as the source of generated package truth: if package docs disagree with source code, update the compiler and regenerate packages.
Do not copy repo-maintainer skills from tools/*/skills/ into user packages.
