Thoughts on life, tech, and math.https://drewstone.github.io/https://drewstone.github.io/posts/lifting-auto-research/https://drewstone.github.io/posts/lifting-auto-research/Auto-research is a loop. Letting an agent optimize that loop lifts it one level up. Doing this recursively builds a tower. Whether the tower ascends or just spins depends on a single property: grounding.Mon, 27 Apr 2026 00:00:00 GMThttps://drewstone.github.io/posts/autonomous-autoreserach/https://drewstone.github.io/posts/autonomous-autoreserach/Sat, 25 Apr 2026 00:00:00 GMThttps://drewstone.github.io/posts/how-i-rebuilt-the-blog/https://drewstone.github.io/posts/how-i-rebuilt-the-blog/Sat, 25 Apr 2026 00:00:00 GMThttps://drewstone.github.io/posts/convergence-as-eval-primitive/https://drewstone.github.io/posts/convergence-as-eval-primitive/Binary pass/fail is useless signal for multi-turn agents.

But they can change their prompts, tools, memory, and planning strategies.
