Skill Instructions

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

  • Compose generators, agents, and nested flows into a workflow graph.
  • Reason about flow state, node inputs, returns, caching, and errors.
  • Use generated package examples for flow graphs and provider-backed flows.

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
draft := ax.NewAx("topicText:string -> draftText:string", nil)
wf := ax.NewFlow(map[string]ax.Value{"id": "docs.coreFlow"}).
  Execute("draft", draft, map[string]ax.Value{
    "reads": ax.Array("topicText"),
    "writes": ax.Array("draftResult", "draftText"),
  }).
  Returns(map[string]ax.Value{"draftText": "draftText"})

More Patterns

Typed programs

Build each flow node from its own input/output contract.

Go
classifier := ax.NewAx("requestText:string -> route:class \"support, sales, engineering\"", nil)
responder := ax.NewAx("requestText:string, route:string -> responseText:string", nil)

Class decision

Declare reads and writes so the responder waits for the typed route.

Go
branchFlow := ax.NewFlow(map[string]ax.Value{"id": "docs.branchFlow"}).
  Execute("classifier", classifier, map[string]ax.Value{"reads": ax.Array("requestText"), "writes": ax.Array("classifierResult", "route")}).
  Execute("responder", responder, map[string]ax.Value{"reads": ax.Array("requestText", "route"), "writes": ax.Array("responderResult", "responseText")}).
  Returns(map[string]ax.Value{"route": "route", "responseText": "responseText"})

Parallel fan-out and join

Independent reads let research and audience analysis share one planner group.

Go
parallelFlow := ax.NewFlow(map[string]ax.Value{"id": "docs.parallelFlow"}).
  Execute("research", research, map[string]ax.Value{"reads": ax.Array("topicText"), "writes": ax.Array("researchResult", "factList")}).
  Execute("audience", audience, map[string]ax.Value{"reads": ax.Array("topicText"), "writes": ax.Array("audienceResult", "audienceAngle")}).
  Execute("join", join, map[string]ax.Value{"reads": ax.Array("factList", "audienceAngle"), "writes": ax.Array("joinResult", "briefText")}).
  Returns(map[string]ax.Value{"briefText": "briefText"})

Draft, critique, revise

A linear refinement pipeline makes each dependency explicit.

Go
refineFlow := ax.NewFlow(map[string]ax.Value{"id": "docs.refineFlow"}).
  Execute("draft", draft, map[string]ax.Value{"reads": ax.Array("topicText"), "writes": ax.Array("draftResult", "draftText")}).
  Execute("critique", critique, map[string]ax.Value{"reads": ax.Array("draftText"), "writes": ax.Array("critiqueResult", "critiqueText")}).
  Execute("revise", revise, map[string]ax.Value{"reads": ax.Array("draftText", "critiqueText"), "writes": ax.Array("reviseResult", "revisedText")}).
  Returns(map[string]ax.Value{"revisedText": "revisedText"})

Run a flow

Forward accepts the context, provider client, public inputs, and options.

Go
output, err := parallelFlow.Forward(
  ctx, client,
  map[string]ax.Value{"topicText": "Typed LLM workflows"},
  nil,
)

Relevant API Surface

  • Flow: axllm.NewFlow, axllm.AxFlow

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.
