Sound familiar?
Wanted self-improvement for our team's agents; every article was about RL and fine-tuning. Budget says no. Turns out you don't train anything - install a skill that makes the agent write structured notes on every correction. Effect was immediate.

I gave my agent a mistakes.md and told it to append on every error. Three months later it's a diary nobody reads - including the agent. Reviews need formats, trigger moments and promotion/pruning rules. 'Just write it down' is not a system.

The combo that actually works: auto-capture plus human triage. Hooks write command failures and my corrections into learnings; I spend ten minutes weekly scanning and merging the good ones into rules. Self-improvement isn't magic - it's human-machine engineering.

FAQ
Q: Can you really self-improve without fine-tuning?
A: Yes - the mainstream path is external memory. Errors, corrections and best practices written as structured files, loaded before tasks, updated after. self-improving (207,167 installs) is exactly this: pure external memory that can even extract new skills from experience.
Q: What should experience records look like?
A: Structured, not a diary. self-improving-agent-next splits records into errors, corrections and capability gaps, each with an ID and state transitions - only entries meeting conditions promote to long-term rules. Format plus lifecycle keeps records from rotting.
Q: When should review trigger?
A: At least four moments: command failure, user correction, session end, and after major tasks. self-improving-agent-skill covers all four - auto-extracts experience after tasks, abstracts reusable patterns, and self-corrects on errors.
Q: How do I avoid cementing bad lessons?
A: Add verification. self-evolving runs single-variable mutation experiments on detected friction points and only promotes a rule after three comparable wins; mimo-self-improvement-loop's Self-Harness includes a dedicated fix-verification stage. Test the improvement before shipping it.
Q: What about team-level self-improvement?
A: Aggregate personal learnings into team SOPs. openclaw-self-improvement turns repeated failures into logged learnings, binary eval loops and SOP documents - 3,167 installs; run it in a personal workspace first, then roll it out.
Q: What does Deep Skill Finder do here?
A: Two things: auto-searches gap-filling skills when a capability hole appears, and finds reference implementations when you promote experience into new skills. All download counts come from a live API - verify any on meyo.life.
