Ax LLM Quick Reference For Go

This skill helps an agent write Go code with the generated Ax package github.com/ax-llm/ax/packages/go. 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: Go.
• Package: github.com/ax-llm/ax/packages/go.
• 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-goja.

Core Pattern

go
import ax "github.com/ax-llm/ax/packages/go"

llm := ax.NewAI("openai", map[string]ax.Value{"apiKey": os.Getenv("OPENAI_API_KEY")})

Relevant API Surface

• Signatures: axllm.S, axllm.FieldType, axllm.AxSignature
• AxGen: axllm.NewAx, axllm.AxGen
• AxAI: axllm.NewAI, axllm.OpenAICompatibleClient, axllm.OpenAIResponsesClient, axllm.GoogleGeminiClient, axllm.AnthropicClient, axllm.AxUsageContext, axllm.AxUsageEvent, axllm.AxUsageObserver, axllm.SetUsageObserver, axllm.AxBalancer, axllm.AxBalancerAdaptiveStrategy, axllm.AxBalancerStatsStore, axllm.AxInMemoryBalancerStatsStore, axllm.CreateBalancerRouteStats, axllm.UpdateBalancerRouteStats, axllm.SampleBalancerRouteHealth, axllm.MultiServiceRouter, axllm.ProviderRouter
• Agents And RLM: axllm.NewAgent, axllm.AxAgent
• Flow: axllm.NewFlow, axllm.AxFlow
• 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.
