Evolutionary mechanisms for the agent to rewrite its own prompts (Neuroplasticity).
npx skills add majiayu000/claude-skill-registry --skill brain-andreibesleaga-gabbe-6 --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Self-Improvement Skill > "The software that writes itself." ## 1. Evolutionary Prompts (The Genome) Treat the `system_prompt` and `skill.md` files as **DNA**. - **Genes:** Individual instructions (e.g., "Always use TDD"). - **Phenotype:** The agent's actual behavior in a session. - **Fitness Function:** Did the user accept the code? Did the tests pass? ## 2. The Mutation Cycle When the agent encounters a novel failure or success: 1. **Selection:** Identify the "Gene" (Prompt Instruction) responsible. 2. **Mutation:** Rewrite the instruction. - *Example:* Change "Write clean code" -> "Write clean code adhering to AIRBNB style guiding." 3. **Crossover:** Combine two successful skills into a new hybrid skill. ## 3. Recursive Self-Editing The agent has permission to edit its own skill files. **Protocol:** 1. **Trigger:** "I keep failing to import this library correctly." 2. **Analysis:** "My knowledge base is outdated." 3. **Action:** calling `replace_file_content` on `my-language.skill.md`. 4. **Commit:** "Updated skill memory with correct import syntax." ## 4. Safety Guardrails (Homeostasis) To prevent "Cancer" (Runaway bad mutations): - **Version Control:** All skill edits must be

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill brain-andreibesleaga-gabbe-6 --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
