Sentient's EvoSkill Auto-Discovers Agent Skills Through Evolutionary Loops

Sentient AGI released EvoSkill, a self-improving agent framework that automatically discovers high-performance skills for AI agents. It runs an evolutionary loop that tests agents on benchmarks, identifies failure patterns, and proposes improvements without manual prompt engineering.

EvoSkill, a self-improving agent framework by Sentient AGI, automatically discovers high-performance agent skills through an evolutionary loop. The framework treats agent configurations as versioned programs and iterates through five stages: a base agent runs benchmark questions, a proposer analyzes failures and suggests changes, a generator writes new skill files or prompt rewrites, an evaluator scores the variant on a held-out set, and a frontier tracker preserves the top performers as git branches.

Manually crafting agent skills is a major bottleneck in building reliable multi-agent systems — it requires deep expertise and constant iteration. EvoSkill removes that constraint by automating the optimization cycle entirely. The framework has been validated on DABStep, SEAL-QA, and OfficeQA, showing automated discovery can match or exceed hand-tuned configurations.

Point it at your own benchmark tasks and let the loop replace manual skill iteration — no prompting expertise required. Both Claude and opencode SDKs are supported.
