AUTO-IMPROVING SOFTWARE

Bedi runs an entire agent development lifecycle through five Claude Code prompts that scaffold, harden against spec, add capabilities, fix eval failures, and reconcile drift between docs, code, and config across his Agno-based platform. The Improve loop derives 8-12 probes from an agent's instructions, runs each against the live container via cURL, judges PASS or FAIL from container logs, then iterates up to five rounds picking levers like tightening rules, swapping tools, or bumping num_history_runs until probes pass, while Hill Climb runs the saved eval suite and fixes regressions in place.

CODEX IS FOR PROSUMERS - HERE'S WHY (AND HOW) TO SWITCH

a16z's Olivia Moore migrated her agentic workflows from Claude Cowork and Claude in Chrome to OpenAI's Codex, recommending most non-technical knowledge workers do the same now that the February desktop app, Plugins, and Automations collapse the ChatGPT-Claude-Cowork interface switching into one product. Codex ships one-click installable Skills she expects to anchor an internal and cross-user marketplace given that non-programmer Skill setup attempt rates likely sit below 10% on Claude, while Codex Pets give low-friction task status updates for users who do not live in an IDE.

THE MAIN PATH TO TRULY CREATIVE AI

AI lacks creativity akin to humans due to the absence of intrinsic drives and subjective experiences. Emulating feelings could enhance AI's creative capabilities, but raises ethical concerns. Designing AI to genuinely feel and desire might lead to unintended consequences, akin to responsibility seen in parenting.
