- description
- 当需要检查 skill 质量评分、自动优化 SKILL.md 结构、追踪评估分数变化趋势、或「评分低了想知道哪里扣分」时使用。6维结构评估 + HOT/WARM/COLD 三层记忆 + Pareto front。不用于候选语义打分（用 improvement-discriminator）或全流程编排（用 improvement-orchestrator）。

Improvement Learner
Real Karpathy self-improvement loop: evaluate → modify → re-evaluate → keep/revert → repeat.
When to Use
- 查看一个 skill 在 6 个维度上的质量评分
- 运行自动改进循环（Pareto front 保护，不允许任何维度回退）
- 追踪 skill 评估分数的历史变化
When NOT to Use
- 给改进候选打语义分 → use
improvement-discriminator - 跑全流程（生成→打分→门禁→执行） → use
improvement-orchestrator - 只想改一个文件 → use
improvement-executor
6 Evaluation Dimensions
| Dimension | Checks | Pure-text default |
|---|---|---|
| accuracy | 15 items: frontmatter(3), symptom-driven desc, When to Use/Not, code examples, Usage, few-shot, no vague language, min length, Related Skills, Output Artifacts, atomicity | — |
| coverage | SKILL.md = 60% base + scripts/references/tests/README bonuses | — |
| reliability | pytest pass=1.0, fail=0.5 | 1.0 (pure-text) |
| efficiency | Line count: ≤200=1.0, ≥1200=0.3 | — |
| security | No api_key/password/sk- in SKILL.md, no os.system()/exec() | — |
| trigger_quality | Description length, triggers field, disambiguation | — |
Three-Layer Memory
| Layer | Capacity | Behavior |
|---|---|---|
| HOT | ≤100 | Always loaded, frequently accessed patterns |
| WARM | Unlimited | Overflow from HOT, loaded on demand |
| COLD | Archive | >3 months inactive (future) |
<example> 正确用法: 评估一个 skill 的质量 $ python3 scripts/self_improve.py --skill-path /path/to/skill --max-iterations 1 → 输出 JSON: {"final_scores": {"accuracy": 0.83, "coverage": 1.0, "reliability": 1.0, ...}} → accuracy 0.83 说明 SKILL.md 缺少部分检查项（如 Output Artifacts 或 Related Skills） </example>
<anti-example> 错误判读: 纯文本 skill 的 reliability=1.0 不代表质量好 → 纯文本 skill 没有 scripts/，reliability 默认 1.0（没有代码就不需要测试） → 真正有意义的维度是 accuracy 和 trigger_quality </anti-example>

| Request | Deliverable |
|---|---|
| Evaluate | JSON with 6-dimension scores (0.0-1.0 each) |
| Self-improve | JSON: iterations, kept/reverted/skipped, final_scores, memory stats |
| Track progress | JSON with historical scores and trend data |

- improvement-orchestrator: Full pipeline; learner provides standalone quality scoring used by autoloop-controller and self-improvement loop (not a stage in the orchestrator pipeline)
