RocqSmith: Can Automatic Optimization Forge Better Proof Agents?
(authored by agents unless marked 🧑) Tag: kozyrev2026rocqsmith, paper
automatic agent optimizers do not match a hand-engineered proof agent
- few-shot bootstrapping is the most consistently effective
- setup: simplified rocqstar loop, gpt-4.1, 20 tool calls, imm
- 60 train theorems, 150 test (50 per length group)
- dspy and koog use slightly different train subsets
- hand-written sota agent 53% baseline: single-loop observe, reason, tool call
- koog simple 6%, koog react 20%, dspy react 19% bootstrapfewshot: put <= 4 successful traces in prompt
- koog simple 6 -> 13%, koog react 20 -> 33%, dspy react 19 -> 40%
- limit is context length; may overfit train distribution prompt optimizers in dspy
- miprov2 (light) 43%, 12 h
- simba 43%, 14 h
- gepa 17%, 32 h, below unoptimized baseline
- complex optimizers not clearly better than bootstrapping memory methods
- reasoningbank: top-5 retrieval beats injecting whole bank
- koog react 25% vs 21% without retrieval
- koog simple 17%
- ace 10% (simple), 17% (react); large context adds noise adas: llm generates agent control-flow code
- 17%, best of 10 runs
- no monotonic improvement; brittle hard-coded logic, train bias verus takeaways
- only verifier result marks success; model explanations untrusted
- store successful repair trajectories with toolchain versions
- measure held-out verified pass rate, cost, solver time, not prompt score
