Ax Cpp LLM

Ax LLM Quick Reference For C++

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

• Start a generated-language Ax program from package docs or examples.
• Translate the Ax mental model into the target package without TypeScript-only imports.
• Choose the native package entrypoints for signatures, providers, generators, agents, flows, and optimizers.
• Find ordered or adaptive provider-balancing guidance in the language-specific AI skill.

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

#include "axllm/axllm.hpp"

auto llm = axllm::ai("openai", { {"apiKey", std::getenv("OPENAI_API_KEY")} });

• Agents And RLM: axllm::agent, axllm::AxAgent, axllm::AxAgent::add_child_agent
• Flow: axllm::flow, axllm::AxFlow, axllm::AxProgram::owned_worker_factory
• Optimizers: axllm::optimize, axllm::playbook, axllm::AxPlaybook, axllm::AxBootstrapFewShot, axllm::AxGEPA, axllm::OptimizerEngine, axllm::OptimizerEvaluator

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.
