Autonomous coding agents hit the ARM stage with OpenAI Symphony + Linear

The Gist

• Alessio Fanelli runs fully autonomous coding agents using OpenAI Symphony + Linear
• Agents handle dev lifecycle with zero babysitting, tracking token costs per task
• Codex autonomously scouts $10K Pokémon cards on eBay for Merlin Games
• New category of small business enabled by AI agent workflows

• OpenAI Symphony + Linear enables fully autonomous coding workflows with zero babysitting, where Linear acts as a state machine and Symphony manages agents throughout the development lifecycle.
• Codex can autonomously browse eBay, extract PSA certificate numbers, and flag underpriced Pokémon cards ($10K–$20K range) for small businesses like Merlin Games.
• Agent manager is a better mental model than agent prompter for scaling autonomous AI workflows.
• Local Mac Minis don’t scale for AI workflows, and cloud VPS unlocks better performance and scalability.
• Purging skills files (like CLAUDE.md) entirely, rather than adding more instructions, can improve agent performance.
• AI enables a new category of small businesses by automating high-value, repetitive tasks like price scouting.

• Adopt an agent manager mindset (vs. prompter) to scale autonomous AI workflows.
• Use cloud VPS over local machines (e.g., Mac Minis) for scalable AI agent deployments.
• Purge outdated or bloated skills files (e.g., CLAUDE.md) to improve agent efficiency.
• Explore AI for automating high-value, repetitive tasks in small business operations (e.g., price scouting).

• 221 million tokens (Token cost tracking per task in OpenAI Symphony workflows.)
• $10K–$20K (Price range of Pokémon cards autonomously scouted by Codex on eBay.)
