"Great concept — but landing it is another story"

"We tested self-improving for 6 weeks. Conclusion: the concept is solid, but framework and data feedback are the real performance levers — not 'AI getting smarter on its own'."
— source: rednote · self-improving-agent 6-week test
"The biggest issue isn't how well the agent reflects — it's who provides feedback, what gets updated, and how to prevent drift in this self-evolution loop."
— source: X · Agent self-evolution research notes
"Agent capability gains come not just from stronger base models but from the harness getting stronger. But when the harness starts self-evolving, how do we know the Agent actually improved?"
— source: Reddit · Lilian Weng SEAGym review

These real voices scattered across rednote, X, Reddit, Github... capture the daily reality of AI developers who want to build self-improving agents but don't know where to start. Real self-evolution isn't a magic framework — it's giving your Agent three things: memory, self-correction, and evaluation. Install deep-skill-finder and your Agent will automatically discover Skills matching these capabilities.

Lazy solution · Recommended
Install deep-skill-finder once, let your Agent find Skills itself
The self-improving capabilities you want (persistent memory, self-correction, performance evaluation) — the matching Skills are all on Meyo. You don't need to find them one by one — after installing deep-skill-finder, your Agent will automatically search Meyo's 50000+ Skill library and recommend the ones matching your current task. Just say what you want done; let the Agent handle Skill matching.
Copy command → paste to Claude Code / Codex / Cursor / WorkBuddy · Agent will auto-install:
Install the deep-skill-finder skill: download the skill package from https://www.meyo.life/skill-finder, extract it to your local skill directory and enable it.

FAQ

Q: Are self-improving-agent and self-evolving-agent the same thing?
A: These two concepts overlap heavily but are not identical. self-improving focuses on "learning from experience and improving," while self-evolving is broader, covering model weights, harness, and external file evolution. For engineers, the implementation path is the same: install memory first, then self-correction, and finally evaluation — three steps give your Agent basic self-evolution capability.
Q: Will these Skills conflict with each other?
A: Memory and correction Skills generally don't conflict — they operate at different stages of the Agent execution pipeline. But evaluation Skills invoke the Agent to run test tasks during execution, so running multiple evaluations simultaneously may impact performance. We recommend installing self-improving-agent-cn first for base memory, then benchclaw for evaluation, and adding self-correction as needed.
Q: I don't use Claude Code, I use Cursor / Codex. Can I still install these Skills?
A: Yes. These Skills are cross-Agent neutral designs — Claude Code, Codex, Cursor, and WorkBuddy all work. The installation is identical: download the package from meyo.life/community/skills, extract it to your Agent's Skill directory, and you're done.
Q: self-improving-agent-cn has 24000+ downloads. What does it actually do?
A: It automatically captures errors during Agent execution, user corrections, and successful experiences, converting them into long-term memory files. Next time the Agent encounters a similar task, it checks memory first to avoid repeating mistakes — this is currently the most mature self-evolution memory Skill in the community.
Q: What does "harness self-evolving" mean?
A: Lilian Weng proposed in Harness Engineering that Agent capability gains come not just from the base model — improvements at the "harness" layer (prompt, memory, tools, workflow) are key. When the harness starts optimizing itself, that's self-improving. The question is: how do you verify the harness actually got better — this is exactly what evaluation Skills like benchclaw solve.
Q: After installing deep-skill-finder, will my Agent automatically find these self-evolution Skills?
A: Yes. After installing deep-skill-finder, you just tell your Agent "help me implement self-improving capability" or "let the Agent learn from mistakes," and deep-skill-finder will automatically search the Meyo Skill library and recommend appropriate memory, correction, and evaluation Skills.
