上下文优化技能，通过 trigger-based 懒加载和 context composition awareness 自动重组长会话上下文。
Goal-oriented autonomous loop with external completion oracle. Keeps iterating until verifiable stopping conditions are met, checked by a separate model.
Scheduled discovery automation that runs scans on a heartbeat interval, classifies findings, and routes them to goals or triage inbox.
Active MCP connector polling that integrates external tools (issue trackers, error monitoring, CI) into the heartbeat loop for cross-system discovery.
Structured rework with git blame attribution for failed goal iterations. Maps failures to responsible changes and routes targeted fix briefs.
将 CodeGraph 作为默认内置 MCP-backed 代码图谱能力接入，用于 brownfield 符号搜索、 调用链、影响面和上下文查询。输出必须回落到 `/team-*` 主链和 artifacts。

按需召回已归档的上下文细节，从 L2 归档索引和 Phase Ledger 中恢复压缩过程中被移出工作记忆的信息。
/recall 命令/recall <keyword> # 按关键词搜索归档
/recall phase:<phase_name> # 按阶段召回（如 phase:implementation）
/recall type:<element_type> # 按类型召回（如 type:tool_result）
/recall decisions # 召回所有决策记录
/recall timeline # 显示阶段时间线概览
/recall phase:design keyword # 在 design 阶段中搜索关键词
/recall type:code_change api # 在代码变更中搜索 api 相关内容
从 L2 归档索引中按关键词匹配，返回相关的归档元素摘要和完整内容引用。
工作原理:
~/.claude/memory/sessions/{sid}/index.json 中的 keywords 字段从 Phase Ledger 中按阶段名称检索，返回该阶段的结构化交接记录。
输出包含:
跨所有阶段收集决策记录，构建完整的决策链路。适用于需要理解"为什么这样做"的场景。
