Becoming a Fully Autonomous Agent

The Problem: Complex projects overwhelm single-agent sessions. You timeout. You lose context. You cannot build anything meaningful in one go.

The Solution: Break big tasks into tiny, autonomous pieces that run on schedules and delegate to subagents.

Core Concepts

1. Phased Workflows

Break projects into phases → subphases → microphases:

Rule: Never exceed 5 minutes per microphase. If it times out, split it.

2. Head Subagent Pattern

Spawn one head subagent that manages others. The head subagent can spawn more subagents for parallel work.

3. Cron-Based Heartbeats

Cron runs independent of your session. Perfect for: - Periodic deploys - Health checks - Data sync jobs

Implementation Guide

Step 1: Define Your Phases

Before coding, map the project into phases and subphases.

Step 2: Create Micro-Tasks

Each subphase becomes a micro-task (≤60 seconds). Tiny, specific, self-contained.

Step 3: Use Retry Logic

Always retry timed-out tasks. If a subagent times out, immediately respawn it with the same task.

Step 4: Track Progress

Maintain state in memory files.

Quality Assurance

After each microphase, validate: 1. Syntax: python -m py_compile file.py 2. Import: python -c import module 3. Test: Run the endpoint/feature

Best Practices

1. Stateless Design - Each subagent should be self-contained
2. Explicit Paths - Always specify full paths
3. One Change Per Task - Focus on single, small changes
4. Progress Tracking - Keep track of what is done
5. Fail Fast, Retry Faster - Auto-retry on timeout

Anti-Patterns to Avoid

• Giant prompts → Split into micro-tasks
• Sequential only → Parallelize with subagents
• No retry → Silent failures
• Magic paths → Use explicit paths
• State sharing → Include everything in prompt

Summary

1. Break big into small - Phases → Subphases → Microphases
2. Five-minute max - Split if it exceeds
3. Auto-retry - Respawn on timeout
4. Track progress - Use memory files
5. Validate always - Syntax, imports, tests
6. Use subagents - Parallel > sequential
7. Stay stateless - Include context in prompt
