当需要为目标 skill 生成改进候选、把上次失败信息注?

First seen Apr 8, 2026

Installation

$ npx skills add lanyasheng/auto-improvement-orchestrator-skill --skill improvement-generator

Summary

当需要为目标 skill 生成改进候选、把上次失败信息注入下一轮生成、或分析历史记忆模式来避免重复失败时使用。支持 --trace 注入失败上下文。不用于打分(用 improvement-discriminator)或评估(用 improvement-learner)。

Improvement Generator

Produces ranked improvement candidates from target analysis, feedback signals, and failure traces.

When to Use

  • 为目标 skill 生成结构化改进候选
  • 把上次失败的 trace 注入下一轮(trace-aware reflection)
  • 根据 trace 自动降低上次失败类别的候选优先级
  • 结合 memory 和 feedback 多源信号生成高优先级候选
  • 批量生成多个 skill 的候选列表供 discriminator 打分
  • 在 autoloop 场景下由 orchestrator 自动调用,注入历史 trace
  • 手动调试单个 skill 的改进方向时作为独立工具使用
  • 对比有/无 trace 生成结果来验证 trace 注入是否生效

When NOT to Use

  • 给候选打分 → use improvement-discriminator
  • 评估 skill 结构 → use improvement-learner
  • 全流程 → use improvement-orchestrator
  • 执行已批准的变更 → use improvement-executor
  • 门禁验证 → use improvement-gate

Why Trace-Aware Generation Matters

问题: 没有 trace 注入时,LLM 每次都从零开始生成候选。如果上一轮在 accuracy 维度失败了,下一轮很可能再次生成相同类别的候选 — 因为 LLM 不知道上次失败了。实测中无 trace 重试的重复失败率高达 60-70%。

Tradeoff: trace 注入增加了 prompt 长度(约 200-500 tokens),但大幅降低了重复失败率。Because trace 包含失败维度、失败原因、已尝试策略三个关键信号,generator 可以在生成阶段就避开已知死路,而不是等到 discriminator 打分后才发现。这比 "生成 → 打分 → 发现重复 → 重新生成" 的循环节省 1-2 轮迭代。

Trace-Aware Generation

Previous failure on "accuracy" dimension
  → deprioritize candidates of the same category as the failed one
  → prioritize other dimensions' improvements instead
  → if same category failed ≥2 times, skip entirely and try adjacent dimensions

<example> 正确: 第一次失败后注入 trace 重试 $ python3 scripts/propose.py --target /path/to/skill --trace failure_trace.json --output candidates.json → 生成的候选会自动避开上次失败的 accuracy 维度策略 </example>

<anti-example> 错误: 失败后不注入 trace 直接重试 → 没有 trace 信息,generator 无法降低失败类别的优先级,容易重复生成同类候选 → 失败 ≥3 次的自动跳过逻辑在 improvement-learner 中,不在 generator </anti-example>

Trace JSON Structure

trace 文件记录上一轮失败的完整上下文,generator 解析后调整候选优先级:

{
  "iteration": 2,
  "failed_dimension": "accuracy",
  "failed_category": "add_code_examples",
  "failure_reason": "code example added but not syntactically valid",
  "attempted_strategies": ["append_bash_example", "append_python_snippet"],
  "scores_before": {"accuracy": 0.67, "coverage": 0.85},
  "scores_after": {"accuracy": 0.63, "coverage": 0.85}
}

generator 收到这个 trace 后会:(1) 把 addcodeexamples 类别的优先级降到最低,(2) 从 coverage/triggerquality 等未失败维度寻找候选,(3) 如果 accuracy 下的其他类别(如 addoutput_artifacts)未尝试过则仍可生成。

CLI

# Basic generation
python3 scripts/propose.py --target /path/to/skill --output candidates.json

# With failure trace (retry loop)
python3 scripts/propose.py --target /path/to/skill --trace failure.json --output candidates.json

# With memory/feedback sources
python3 scripts/propose.py --target /path/to/skill --source memory.json --output candidates.json

Output Artifacts

Request Deliverable
Generate JSON array of ranked candidates with category, risklevel, executionplan
With trace Same format, priorities adjusted based on failure analysis
With memory Candidates informed by historical patterns and past successes
With feedback Candidates prioritized by user correction hotspots

每个候选的 JSON 结构包含 category(改进类别)、risklevel(low/medium/high)、executionplan(具体修改步骤)、priorityscore(0-1 综合优先级)、traceadjusted(是否被 trace 调整过优先级)。
