**learn-claude-code** is a reference implementation that helps developers build **fully-autonomous, tool-enabled AI coding agents** capable of independent reasoning, multi-agent collaboration, and persistent task management using Anthropic's Claude models.

The repository provides a complete blueprint for constructing autonomous coding assistants that can decompose complex software requests, execute shell commands, manage background jobs, and coordinate with peer agents. By examining the source code in [`agents/s_full.py`](https://github.com/shareAI-lab/learn-claude-code/blob/main/agents/s_full.py) and supporting skill definitions, developers can understand how to assemble loop-driven reasoning, context compression, and dynamic skill loading into a cohesive system.

## Core Architecture of the Autonomous Agent

The foundation of the AI coding agent resides in [`agents/s_full.py`](https://github.com/shareAI-lab/learn-claude-code/blob/main/agents/s_full.py), which implements a **perpetual agent loop** that processes LLM messages, executes tool calls, and maintains context across long-running sessions.

### Loop-Driven Reasoning and Tool Use

At the heart of the system is the `agent_loop()` function (lines 53-81 in [`agents/s_full.py`](https://github.com/shareAI-lab/learn-claude-code/blob/main/agents/s_full.py)), which creates a continuous cycle of reasoning and action. The loop sends messages to the Claude model, interprets responses, and dispatches to appropriate handlers defined in `TOOL_HANDLERS` (lines 76-106).

The agent comes equipped with a comprehensive `TOOLS` definition enabling:
- **Bash execution** for running commands and scripts
- **File I/O** for reading and writing source code
- **Background job management** for long-running processes
- **Task management** for tracking work items

### Context Compression and Skill Loading

To maintain performance within token limits, the repository implements `microcompact()` and `auto_compact()` functions (lines 25-44) that intelligently compress conversation history. Additionally, the `SkillLoader` class (lines 98-115) enables on-demand injection of domain knowledge from markdown skill files, allowing the agent to acquire specialized coding capabilities dynamically.

## Multi-Agent Collaboration and Task Management

Beyond single-agent operation, learn-claude-code demonstrates patterns for **autonomous multi-agent systems** where multiple coding agents work concurrently.

### Teammates and Sub-Agents

The `TeammateManager` class (lines 99-152) implements persistent autonomous peers that can claim tasks, enter idle states, and shut themselves down when work completes. These teammates communicate via a `MessageBus` and operate independently within the same project context.

For isolated exploration, the `run_subagent()` function (lines 58-95) spawns sandboxed **sub-agents** that can investigate specific code paths or experiment with solutions without affecting the main agent's context.

### Persistent Task Board

The `TaskManager` class (lines 61-88) maintains a file-based persistent task board where teammates can auto-claim available work. This enables distributed workflows where one agent might write tests while another implements functions, coordinated through a shared JSON-based task store.

### Background Job Execution

The `BackgroundManager` (lines 27-36) handles asynchronous command execution with notification draining, allowing the agent to launch long-running builds or test suites and periodically check status without blocking the main reasoning loop.

## Implementation Examples

### Minimal Agent Setup

For developers starting from scratch, the repository provides a compact reference implementation in [`skills/agent-builder/references/minimal-agent.py`](https://github.com/shareAI-lab/learn-claude-code/blob/main/skills/agent-builder/references/minimal-agent.py). This approximately 80-line example demonstrates the core loop with three basic tools:

```python
from anthropic import Anthropic
from pathlib import Path
import subprocess, os

client = Anthropic(api_key=os.getenv("ANTHROPIC_API_KEY"))
MODEL = os.getenv("MODEL_NAME", "claude-sonnet-4-20250514")
WORKDIR = Path.cwd()

# System prompt, tool definitions, and a simple loop …

```

See the complete implementation in the [minimal-agent.py source](https://github.com/shareAI-lab/learn-claude-code/blob/main/skills/agent-builder/references/minimal-agent.py).

### Spawning Autonomous Teammates

To create a persistent coding partner that operates independently:

```python
from agents.s_full import TEAM

# Spawn a teammate named "alice" that will act as a coder.

TEAM.spawn(
    name="alice",
    role="coder",
    prompt="Write a well‑tested Python function for quicksort."
)

```

The `spawn()` implementation resides at [agents/s_full.py#L21-L34](https://github.com/shareAI-lab/learn-claude-code/blob/main/agents/s_full.py#L21-L34).

### Task Creation and Management

Creating work items for the autonomous task board:

```python
from agents.s_full import TASK_MGR

# Create a task on the board

task_json = TASK_MGR.create(
    subject="Refactor utils module",
    description="Split helper functions into separate files."
)
print(task_json)

# Later, a teammate can auto‑claim it via the idle loop,

# or you can claim manually:

TASK_MGR.claim(task_id=1, owner="alice")

```

The task management logic is implemented at [agents/s_full.py#L61-L88](https://github.com/shareAI-lab/learn-claude-code/blob/main/agents/s_full.py#L61-L88).

### Running Background Builds

Execute long-running processes without blocking the agent's reasoning:

```python
from agents.s_full import BG

# Start a long‑running build in the background

bg_id = BG.run("make -C myproject all")
print(f"Background job started: {bg_id}")

# Periodically check its status

print(BG.check(bg_id))

```

View the background manager implementation at [agents/s_full.py#L27-L36](https://github.com/shareAI-lab/learn-claude-code/blob/main/agents/s_full.py#L27-L36).

## Frequently Asked Questions

### What is the difference between a sub-agent and a teammate in learn-claude-code?

**Sub-agents** are temporary, sandboxed instances created via `run_subagent()` (lines 58-95) for isolated exploration of specific problems, while **teammates** are persistent autonomous agents managed by `TeammateManager` (lines 99-152) that can claim tasks, maintain idle states, and shut themselves down. Sub-agents are disposable investigation tools, whereas teammates are long-running collaborators with their own lifecycle management.

### How does the agent avoid exceeding token limits during long coding sessions?

The repository implements **context compression** through `microcompact()` and `auto_compact()` functions in [`agents/s_full.py`](https://github.com/shareAI-lab/learn-claude-code/blob/main/agents/s_full.py) (lines 25-44). These functions intelligently summarize and compact conversation history to stay within the model's context window, ensuring the agent can maintain reasoning coherence across extended development sessions without losing critical information.

### Can I extend the agent with custom tools for specific programming languages?

Yes. The agent's capabilities are defined in the `TOOLS` and `TOOL_HANDLERS` dictionaries in [`agents/s_full.py`](https://github.com/shareAI-lab/learn-claude-code/blob/main/agents/s_full.py) (lines 76-106). You can add new tool definitions following the JSON schema patterns shown in [`skills/agent-builder/references/tool-templates.py`](https://github.com/shareAI-lab/learn-claude-code/blob/main/skills/agent-builder/references/tool-templates.py), then implement corresponding handler functions to support domain-specific operations like compiling Rust code or running JavaScript linters.

### Is learn-claude-code suitable for production deployment?

The repository is designed as a **reference implementation and educational framework** rather than a production-ready service. While it demonstrates robust patterns for autonomous agent architecture including shutdown controls (`handle_shutdown_request()`) and plan approval (`handle_plan_review()`) at lines 59-73, production deployments would require additional hardening, authentication, sandboxing, and error handling beyond the scope of this teaching repository.
