Skill Instructions

This skill helps an agent write C++ 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: C++.
• 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

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

Relevant API Surface

• AxGen: axllm::ax, axllm::AxGen
• Tools: axllm::Tool, axllm::Tool
• MCP: axllm::AxMCPClient, axllm::AxMCPStreamableHTTPTransport, axllm::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.
