# 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 ```cpp #include "axllm/axllm.hpp" auto llm = axllm::ai("openai", { {"apiKey", std::getenv("OPENAI_API_KEY")} }); ``` ## Relevant API Surface - Signatures: `axllm::s`, `axllm::FieldType`, `axllm::AxSignature` - AxGen: `axllm::ax`, `axllm::AxGen`, `axllm::run_control`, `axllm::AxRunControl`, `axllm::AxCachingFunction`, `axllm::set_caching_function` - AxAI: `axllm::ai`, `axllm::openai_decisions`, `axllm::AxAIOpenAIDecisionsClient`, `axllm::typesafe`, `axllm::AxAITypesafeClient`, `axllm::AxCancellationToken`, `axllm::AxAIServiceAbortedError`, `axllm::get_supported_ai_models`, `axllm::AxCredentialRequest`, `axllm::AxCredentialProvider`, `axllm::AIClient::owned_worker_factory`, `axllm::AxChatSession`, `axllm::AxStreamHandler`, `axllm::OpenAICompatibleClient`, `axllm::OpenAIResponsesClient`, `axllm::GoogleGeminiClient`, `axllm::AnthropicClient`, `axllm::AxUsageContext`, `axllm::AxUsageEvent`, `axllm::AxUsageObserver`, `axllm::set_usage_observer`, `axllm::AxRuntimeHooks`, `axllm::AxRateLimitInfo`, `axllm::AxRateLimiter`, `axllm::AxTracer`, `axllm::AxMeter`, `axllm::AxGlobals`, `axllm::set_rate_limiter`, `axllm::set_tracer`, `axllm::set_meter`, `axllm::AxBalancer`, `axllm::AxBalancerAdaptiveStrategy`, `axllm::AxBalancerStatsStore`, `axllm::AxInMemoryBalancerStatsStore`, `axllm::create_balancer_route_stats`, `axllm::update_balancer_route_stats`, `axllm::sample_balancer_route_health`, `axllm::MultiServiceRouter`, `axllm::ProviderRouter` - Agents And RLM: `axllm::agent`, `axllm::AxAgent`, `axllm::AxAgent::add_child_agent`, `axllm::AxAgent::streaming_forward` - 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.
