SUMMARY

Build an AI agent harness in Rust, from a minimal loop to tools, subagents, memory, teams, worktrees, MCP, and typed tool routing.

A progressive AI Agent Harness tutorial written in Rust.

This repository is a Rust-oriented learning path for building an agent harness. It starts with the smallest agent loop and gradually adds tools, planning, subagents, skills, context compaction, permissions, hooks, memory, multi-agent collaboration, worktree isolation, MCP/plugins, and tool routing.

This project was inspired by shareAI-lab/learn-claude-code. Its chapter design, content organization, and some code ideas reference that project to a certain extent, then reimplement and adapt them for the Rust ecosystem. It is not a line-by-line copy or a simple port; it reorganizes the agent harness topic itself into a runnable Rust tutorial.

Each chapter is an independent runnable Rust crate. You can read them in order or jump directly into a topic to see how a harness capability is expressed through data structures, runtime loops, tool interfaces, and durable state.

Why This Repo

Most LLM examples stop at tool calling. This repo focuses on the runtime around the model:

  • tool dispatch
  • permissions
  • skills
  • memory
  • context compaction
  • subagents
  • background work
  • team protocols
  • worktree isolation
  • MCP plugins
  • typed tool routing

Architecture

learn-claude-code-rs architecture

Audience

  • People who want to understand the internals of coding agents instead of only using existing products.
  • People who want to write AI agents, CLI tools, or automation tools in Rust.
  • Readers who already know LLM APIs and want to learn tool use, subagents, permissions, hooks, memory, and related engineering structures.
  • People interested in the infrastructure behind Claude Code, Codex, Devin, Cursor Agent, and similar coding agents.

Quick Start

Prepare Rust:

rustup update
cargo --version

Configure the model API. The examples use an Anthropic-compatible SDK interface and read configuration from environment variables:

cp .env.example .env

Edit .env:

ANTHROPIC_API_KEY=your_api_key
ANTHROPIC_BASE_URL=your_anthropic_compatible_base_url
ANTHROPIC_MODEL=your_model_name

Run the first chapter:

cargo run -p s01_agent_loop

Run the integrated version:

cargo run -p sfull

Check the whole workspace:

cargo check --workspace

Learning Path

Each chapter is an independent crate that can be run, read, and modified on its own. Reading in order is recommended because later chapters build on earlier structures.

Chapter Directory Topic Description
01 s01_agent_loop Agent Loop Minimal runnable agent with user input, model response, tool calling, and a basic bash tool. Docs: s01.en.md.
02 s02_tool_use Tool Use Extract tools into a trait and add read_file, write_file, and edit_file. Docs: s02.en.md.
03 s03_todo_write Todo Planning Add a todo tool so the agent can maintain a plan and execution state. Docs: s3.en.md.
04 s04_subagent Subagent Start fresh-context subagents for delegated exploration or subtasks. Docs: s4.en.md.
05 s05_skill_loading Skill Loading Load skills from skills/ and inject skill content into context on demand. Docs: s05.en.md.
06 s06_context_compact Context Compact Compact long context while preserving key state. Docs: s06.en.md.
07 s07_permission_system Permission Add permission modes and interactive confirmation for tool calls. Docs: s07.en.md.
08 s08_hook_system Hook System Add lifecycle hooks around tool execution and agent events. Docs: s08.en.md.
09 s09_memory_system Memory Add durable memory for preferences, facts, feedback, and references. Docs: s09.en.md.
10 s10_system_prompt System Prompt Manage system prompts through structured sections and templates. Docs: s10.en.md.
11 s11_error_recovery Error Recovery Recover from tool failures, model errors, transport errors, and truncation. Docs: s11.en.md.
12 s12_task_system Task System Add structured task records with status, owner, and dependencies. Docs: s12.en.md.
13 s13_background_tasks Background Tasks Start, query, and manage long-running background commands. Docs: s13.en.md.
14 s14_cron_scheduler Cron Scheduler Schedule future tasks and reinject them into the loop when due. Docs: s14.en.md.
15 s15_agent_teams Agent Teams Organize multiple agents into teams with roles, inboxes, and messages. Docs: s15.en.md.
16 s16_team_protocols Team Protocols Add durable request-response protocols for multi-agent collaboration. Docs: s16.en.md.
17 s17_autonomous_agents Autonomous Agents Implement long-running workers with idle polling and task claiming. Docs: s17.en.md.
18 s18_worktree_task_isolation Worktree Isolation Use git worktrees to isolate task execution environments. Docs: s18.en.md.
19 s19_mcp_plugin MCP Plugin Connect MCP/plugin tools to the same permission and tool-result loop. Docs: s19.en.md.
20 s20_tool_refactor Tool Refactor Refactor tool registration, routing, dispatch, and macro support. Docs: s20.en.md.
Full sfull Complete Version Integrate previous chapters into one complete agent harness. Docs: sfull.en.md.

Recommended Reading Order

  1. Run s01_agent_loop and understand the minimal loop: user input, model response, tool call, and tool result.
  2. Read s02_tool_use through s04_subagent to understand tools, planning, and delegation.
  3. Read s05_skill_loading through s08_hook_system to see how a demo becomes an extensible system.
  4. Read s09_memory_system through s14_cron_scheduler to understand state, long-running work, and scheduling.
  5. Read s15_agent_teams through s20_tool_refactor to understand multi-agent collaboration, isolated execution, plugins, and tool routing.
  6. Read sfull last to see how the pieces fit together.
