-### Communication context
+### Identity and communication context

 #### What the model sees

-The logged `subagent:communication` runtime context tells delegated children their direct creator’s JSON-encoded id and how to send findings that change the parent’s next action. Sending a message does not end the turn. Root Agents and ordinary Session forks receive no communication context; delegated children receive it only when the standard messaging definition is admitted in the current scope and step. Automatic result delivery remains owned by the subagent service.
+Required `subagent:identity` runtime context identifies each agent by its Session id. Delegated children are identified as subagents and receive their direct parent and root ids. It is independent of Team mode and tool filtering; a missing live root is reported without preventing independent work. When the live root is available, identity context includes messaging and discovery instructions independently for each admitted standard tool. Automatic result delivery remains owned by the subagent service.

 #### Token effect

-One short context entry per delegated child, independent of tree size.

 ### Policy and tools

-One plugin registration provides a dynamic `team:policy` section, required `team:identity` context, and four conditional task tools. Each provider reads the caller’s root Session selection; prompt visibility is independent of tool restrictions. Tree authority and root identity come from `ctx.subagents.rootOf(agent)`. An unavailable root disables Team tools and guidance. Communication and waiting belong to [subagent controls](../../subagent/tool-subagent-control/README.md); the subagent runtime delivers final results.

Identity, discovery, communication, and waiting belong to [subagent controls](../../subagent/tool-subagent-control/README.md) and remain unchanged when Team mode switches.

 ### Scoped registration and teardown

-Tool `when` conditions resolve at step preparation, including the first step of new, forked, and resumed Agents. Policy text is evaluated during prompt assembly; identity is also refreshed at request admission. An already prepared step retains its tool selection, but task operations check the current mode before starting. Plugin disposal removes all registrations through their owning effects.

 The text is identical for the Lead and every descendant and does not change while the plugin stays loaded, so it keeps a stable system-prompt prefix, including between a parent and its `subagent_fork` child. Loading or unloading the plugin changes the system prompt of every member and invalidates their cached prefixes.

-### Team identity runtime context

-#### What the model sees
-
-While Team is enabled and its root is available, required `team:identity` context uses the following text, replacing `<agent-id>` or `<root-id>` with the JSON-encoded Session id derived from the subagent tree. Otherwise it contributes no text. Optional-context suppression cannot remove an enabled identity; the ordinary runtime-context mechanism restores it after compaction.

-##### Root identity

-```markdown
-You are the Team Lead. Your agent id is <agent-id>.
-```
-
-##### Teammate identity
-
-```markdown
-You are a teammate in the Team led by agent <root-id>.

-#### Token effect
-
-Identity is part of the full runtime-context snapshot. Stable retained context adds no new message.
-
-#### KV Cache effect
-
-Identity appends through runtime context while shared system text stays identical across members. An ordinary Session fork in Team mode receives its own root identity; actual provider cache reuse remains best-effort.

 ### Record, replay, and refresh

+Refresh normalizes each complete Session log before reusing volatile fields, so job ids retain the same references in registration events, tool output, and later tool calls.
+
 `pnpm run test:snapshot:record` calls the live LLM and writes the harvested current generation under its canonical versioned filename. Record and refresh never rename or delete a completed generation, including generations of a child role absent from a later run; reviewed source-tree curation removes a predecessor only after the same role has a verified current replacement. Scenarios with an explicit `sessionFormat` remain read-only in record mode. `pnpm run test:snapshot:refresh` stays keyless, runs the selected highest replay input, and writes stdout, owned prompt and tool-schema sidecars, and a fresh current-generation comparable Session output; retained historical scenarios write the separate writer-output oracles instead of a canonical current-format replay generation. Headless and SDK scenarios may add a local `runtime.cordis.yml` patch for execution fixtures. Each composition owner keeps its replay patch beside its live patch; top-level `snapshots/` owns Session-driven scenarios, while other expected outputs stay beside their owning package. [`dsh-llm-replay`](../llm-replay/README.md) serves the recorded streams selected through `DSH_SNAPSHOT_*` environment values.

 For an initial headless live recording with no Session file, temporarily set `input.task` in `snapshot.yml`; the live composition selects the model. After recording, remove that input so the selected Session owns the task. Replay and refresh require existing canonical Session files, and malformed or orphaned roles remain errors.

 ### 录制、回放与刷新

+刷新在复用易变字段之前，会规范化每份完整的 Session 日志，使作业 id 在注册事件、工具输出和后续工具调用中保持相同的引用关系。
+
 `pnpm run test:snapshot:record` 调用在线 LLM（大语言模型），并在规范具名版本文件下写入收集到的当前 generation。record 与 refresh 绝不重命名或删除已完成的 generation，即使后续运行不再产生某个 child 角色也一样；受审阅的源树整理只有在同角色存在已验证的当前替代文件后才移除前代。显式声明 `sessionFormat` 的场景在录制模式下保持只读。`pnpm run test:snapshot:refresh` 保持无密钥，运行选定的最高 replay 输入，并写入 stdout、各 pin 自有的提示词与工具 schema 伴随文件，以及新鲜当前 generation 的可比较 Session 输出；保留历史输入的场景写入单独的 writer 输出比较基准，而非规范当前格式 replay 代际。Headless 与 SDK 场景可通过本地 `runtime.cordis.yml` patch 添加执行 fixture。每个组合 owner 把 replay patch 放在 live patch 旁；顶层 `snapshots/` 拥有 Session 驱动场景，其他预期输出留在其 package owner 旁。[`dsh-llm-replay`](../llm-replay/README.zh.md) 提供通过 `DSH_SNAPSHOT_*` 环境值选择的已记录流。

 首次录制尚无 Session 文件的 headless 在线场景时，临时在 `snapshot.yml` 设置 `input.task`，由在线组合选择模型。录制后移除该输入，让选定 Session 拥有任务文本。回放与刷新必须已有规范 Session 文件，格式错误或缺少 parent 的角色仍会报错。

 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

-Start independent delegations with `subagent` or `subagent_fork` together in one assistant message and continue useful work while they run. When only waiting for their results remains, end your turn instead of sleeping or polling; the next result starts a new turn.
+Start independent delegations with `subagent` or `subagent_fork` together in one assistant message and continue useful work while they run. When only waiting for their results remains, end your turn instead of sleeping or polling; the next result starts a new turn. Collect the subagent results required to complete the task before giving the user a final answer.
+
+Agents may use different working directories; changes to shared files affect other agents. Split parallel write work into disjoint file or directory scopes. Bash, formatters, code generators, and scripts can overwrite concurrent edits without conflict detection; coordinate their changes explicitly. The agent integrating the work must review the final diff and run relevant tests.

 Prefer showing the primary results within your final response alongside a brief explanation. Use ![Description](<path/to/image.png>) when an image supports an explanation or comparison. Use [Description](<path/to/image.png>) when referring to an image or listing files. Enclose Markdown file destinations in angle brackets, especially paths containing spaces. Do not call present just to list edited source files, or run commands to check whether a diff view will appear. Use present to publish complete deliverables, including images, Office documents, spreadsheets, and slide decks, when separate access helps the user. Hosts that support file cards can show the presented file with preview and open actions. Avoid repeating results already shown inline unless the separate card adds useful access. Outside commands, configuration expressions, and code blocks, link every mention of an existing file, including repeats and tables, to its full path relative to the working directory or absolute; append #L24 or #L24-L30 to the target for known lines. Use the filename or a clear alias as the label, adding only enough parent directories to distinguish files; keep full paths out of labels. Default to the name alone; when precise locations matter, append :24 or :24–30, with no # or L in the line suffix.
