Improvement Learner

Real Karpathy self-improvement loop: evaluate → modify → re-evaluate → keep/revert → repeat.

When to Use

  • 查看一个 skill 在 9 个维度上的质量评分(accuracy/coverage/reliability/efficiency/security/triggerquality/leakage/knowledgedensity + 综合分)
  • 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
  • 诊断某个 skill 扣分原因(哪些 checklist item 未通过)
  • 对比纯文本 skill 和带脚本 skill 的评分差异
  • 为 autoloop-controller 提供收敛判断的分数数据
  • 验证改进后分数是否真正提升(改前/改后对比)
  • 使用 --mock 模式快速调试评分逻辑而不消耗 LLM tokens

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
  • 验证改进是否提升 AI 执行效果 → use improvement-evaluator

Why 9 Dimensions Instead of a Single Score

问题: 早期版本用单一加权分(0-100)评估 skill 质量,但发现严重问题:一个 security 有漏洞的 skill 可以靠高 accuracy 和 coverage 拉高总分到 SOLID 级别。单一分数无法区分"全面优秀"和"偏科严重"。

Tradeoff: 9 维度增加了评估复杂度(每个维度需要独立的 checklist 和阈值),但让问题定位变得精确。当 accuracy=0.67 时,直接看哪些 checklist item 未通过就知道要加 Output Artifacts 还是 code examples。Because 维度正交设计(accuracy 管内容完整性,coverage 管文件覆盖度,security 管安全规范),同一个改进只影响 1-2 个维度,不会出现"改了 A 维度意外影响 B 维度"的耦合问题。

9 个维度中 leakage 和 knowledgedensity 是后来加入的:leakage 解决内部项目路径泄露到公开 skill 的问题,knowledgedensity 解决 SKILL.md 看似完整但每个 section 只有 2-3 行缺乏深度的问题。

9 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 —
leakage No internal project references (company-specific paths, internal URLs) —
knowledge_density Depth per section, actionable content ratio —

Why LLM Judge for Accuracy Instead of Regex

问题: 最初 accuracy 维度完全用 regex 匹配(检查 SKILL.md 是否包含 "## When to Use"、是否有 code block 等),但 regex 的判断精度极低。一个 skill 写了 ## When to Use 但内容是 "TBD" 也能通过 regex 检查。实测 regex 与人工评估的相关性 R²≈0.00 — 基本等于随机。

Because accuracy 需要判断内容的语义质量(description 是否 symptom-driven、code examples 是否与 skill 功能相关、是否有 vague language),这些都超出了 regex 的能力范围。LLM judge 对每个 checklist item 做 yes/no 判断,与人工评估的一致率约 85%。

Tradeoff: LLM judge 每次评估消耗约 2000-4000 tokens(约 $0.01-0.02),比 regex 的零成本高。但 --mock 模式可以跳过 LLM 调用,用确定性规则快速返回近似分数,适合调试和 CI 环境。

# Regex vs LLM judge accuracy comparison (from internal benchmark)
# Regex: checks if "## When to Use" heading exists → yes/no
# LLM:   checks if content under heading is actionable, not just "TBD"
regex_score = 0.73   # passes because heading exists
llm_score   = 0.45   # fails because content is placeholder
human_score = 0.40   # agrees with LLM — heading with "TBD" is not useful
# R² correlation: regex vs human = 0.00, LLM vs human = 0.72

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)

HOT 层存储最近评估中频繁出现的失败模式(如"缺少 Output Artifacts"出现 5 次以上)。当 generator 请求改进方向时,HOT 层的高频失败模式会被优先推荐。WARM 层存储所有历史评估结果,按 skill_id 索引,用于趋势分析和回归检测。COLD 层目前未实现,规划中用于归档超过 3 个月未被访问的模式数据。

<example> 正确用法: 评估一个 skill 的质量 $ python3 scripts/selfimprove.py --skill-path /path/to/skill --max-iterations 1 → 输出 JSON: {"finalscores": {"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>

CLI

# 评估(不改动,只看分数)— 默认使用 LLM judge
python3 scripts/self_improve.py --skill-path /path/to/skill --max-iterations 1

# 自改进循环(5 轮)
python3 scripts/self_improve.py \
  --skill-path /path/to/skill \
  --max-iterations 5 \
  --memory-dir /path/to/memory \
  --state-root /path/to/state

# 追踪历史
python3 scripts/track_progress.py --skill-path /path/to/skill --output progress.json

--mock 模式 vs 默认 LLM Judge

--mock 模式跳过所有 LLM 调用,用纯规则(regex + 结构检查)返回分数。适合快速调试评分逻辑、CI pipeline、或不想消耗 token 的场景。代价是 accuracy 维度的精度大幅下降(与人工评估相关性从 85% 降到约 30%)。

# --mock 模式:零 LLM 调用,纯规则评分,~1 秒完成
python3 scripts/self_improve.py --skill-path /path/to/skill --max-iterations 1 --mock
# → {"final_scores": {"accuracy": 0.73, ...}, "mode": "mock", "llm_calls": 0}

# 默认模式:LLM judge 评估 accuracy,~10 秒完成,消耗约 3000 tokens
python3 scripts/self_improve.py --skill-path /path/to/skill --max-iterations 1
# → {"final_scores": {"accuracy": 0.83, ...}, "mode": "llm", "llm_calls": 1}

Output Artifacts

Request Deliverable
Evaluate JSON with 9-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
Mock evaluate Same format as Evaluate but with mode: "mock" and llm_calls: 0

Evaluate 输出还包含每个维度的详细 checklist 结果(哪些 item 通过、哪些未通过),方便定位具体扣分原因。Self-improve 输出包含每轮迭代的 diff(改了什么)、scoresbefore/scoresafter(改前/改后分数)、decision(kept/reverted/skipped)。
