Based on comprehensive analysis, skill-tuning addresses core skill issues and general optimization areas:
Core Skill Issues (自动检测)
| Priority | Problem | Root Cause | Solution Strategy |
|---|---|---|---|
| P0 | Authoring Principles Violation | 中间文件存储, State膨胀, 文件中转 | eliminate_intermediate_files, minimize_state, context_passing |
| P1 | Data Flow Disruption | Scattered state, inconsistent formats | state_centralization, schema_enforcement |
| P2 | Agent Coordination | Fragile call chains, merge complexity | error_wrapping, result_validation |
| P3 | Context Explosion | Token accumulation, multi-turn bloat | sliding_window, context_summarization |
| P4 | Long-tail Forgetting | Early constraint loss | constraint_injection, checkpoint_restore |
| P5 | Token Consumption | Verbose prompts, excessive state, redundant I/O | prompt_compression, lazy_loading, output_minimization |
General Optimization Areas (按需分析 via Gemini CLI)
| Category | Issues | Gemini Analysis Scope |
|---|---|---|
| Prompt Engineering | 模糊指令, 输出格式不一致, 幻觉风险 | 提示词优化, 结构化输出设计 |
| Architecture | 阶段划分不合理, 依赖混乱, 扩展性差 | 架构审查, 模块化建议 |
| Performance | 执行慢, Token消耗高, 重复计算 | 性能分析, 缓存策略 |
| Error Handling | 错误恢复不当, 无降级策略, 日志不足 | 容错设计, 可观测性增强 |
| Output Quality | 输出不稳定, 格式漂移, 质量波动 | 质量门控, 验证机制 |
| User Experience | 交互不流畅, 反馈不清晰, 进度不可见 | UX优化, 进度追踪 |
Key Design Principles
- Problem-First Diagnosis: Systematic identification before any fix attempt
- Data-Driven Analysis: Record execution traces, token counts, state snapshots
- Iterative Refinement: Multiple tuning rounds until quality gates pass
- Non-Destructive: All changes are reversible with backup checkpoints
- Agent Coordination: Use specialized sub-agents for each diagnosis type
- Gemini CLI On-Demand: Deep analysis via CLI for complex/custom issues
Gemini CLI Integration
根据用户需求动态调用 Gemini CLI 进行深度分析。
Trigger Conditions
| Condition | Action | CLI Mode |
|---|---|---|
| 用户描述复杂问题 | 调用 Gemini 分析问题根因 | analysis |
| 自动诊断发现 critical 问题 | 请求深度分析确认 | analysis |
| 用户请求架构审查 | 执行架构分析 | analysis |
| 需要生成修复代码 | 生成修复提案 | write |
| 标准策略不适用 | 请求定制化策略 | analysis |
