name: "ax-cpp-agent" description: "Use when writing C++ code with axllm for agents, child delegation, tools, MCP, citations, persistent playbook learning, stage instructions, runtime state, final typed responses, and direct-respond executor skipping." version: "24.0.5"

AxAgent 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

• Create an RLM agent with tools, child agents, or MCP clients.
• Use clarification, discovery, recall, final, or respond envelopes.
• Require evidence citations, attach a persistent playbook, or add stage-owned actor instructions.
• Harvest run-end failures into the playbook and observe citation or playbook updates.
• Skip the executor stage for no-tool tasks with a distiller respond envelope (directResponse, on by default).
• Save and restore agent runtime state around long-running tasks.

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 helper = axllm::agent("question:string -> answer:string");
auto out = helper.forward(llm, { {"question", "How should I proceed?"} });

Relevant API Surface

• Agents And RLM: axllm::agent, axllm::AxAgent
• MCP: axllm::AxMCPClient, axllm::AxMCPStreamableHTTPTransport, axllm::AxMCPStdioTransport
• Runtime Profiles: axllm::ProcessCodeRuntime, axllm::RuntimeCapabilities, axllm::RuntimeEnvelope, javascript-quickjs, python-pyodide

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.
