岗位会商 Step 1 改用 position-roundtable-intent 智能体，输出 coreGoals/riskWarnings/keyPoints/strategicSignificance 四项数组；支持单轮多张协助卡、按轮次计澄清上限，并兼容旧会话 objective/constraints 映射。

 后端会冻结链条快照并根据链条阶段创建节点。已启动后意图不可再修改；需要重新识别时必须新建会话。
 
+The position workspace selects the dedicated built-in `position-roundtable-intent`
+agent by sending `intent_agent_id` through the shared Step-1 init and stream
+requests. The thread lifecycle, file upload, and SSE transport stay identical
+to the generic multi-agent flow. The dedicated agent permits at most five
+user-assistance rounds; one round may contain multiple independent
+`ask_clarification` cards. `Step1Panel` renders every card separately and
+submits the selected answers together, so cards must never be merged into one
+numbered multi-question card. Only its final `[INTENT_READY]` schema changes to
+the following four string arrays:
+
+```json
+{
+  "coreGoals": ["..."],
+  "riskWarnings": ["..."],
+  "keyPoints": ["..."],
+  "strategicSignificance": ["..."]
+}
+```
+
+The position sidebar and edit dialog render these four fields. Business-chain
+activation requires all four arrays and at least one core goal or strategic
+significance. Historic `objective` / `constraints` / `assumptions` snapshots
+are read through a compatibility mapping only; ordinary multi-agent Step 1 is
+not changed.

 ### 4.2 普通节点问答
 
 `PositionNodeChat` 在发送前调用 `getPositionNodeContext` 获取受长度控制的任务、意图和已交付上游内容，再以 `task_external_context` 作为隐藏上下文发送给当前智能体。

+Position roundtable selects the separately seeded built-in agent
+`position-roundtable-intent` by passing `intent_agent_id` to the shared
+`/api/intent/init` and `/api/intent/stream` endpoints. Its request lifecycle,
+files, and SSE protocol match `roundtable-intent`, but its cap is five
+**user-assistance rounds**. A single round may emit several independent
+`ask_clarification` tool calls; those calls are separate cards, not one card
+containing several numbered questions. Count that as one round by the
+tool-calling AI message, never by card count. Topic-only requests must request
+all material missing decisions as separate cards rather than being treated as a
+resolved intent; after the fifth set is answered it must emit completed final
+JSON without unresolved placeholders. The required arrays are
+`coreGoals`, `riskWarnings`, `keyPoints`, and `strategicSignificance`. Do not
+treat a fresh dedicated-agent `ask_clarification` as stale: it must win over
+a same-run premature `[INTENT_READY]` and leave the UI waiting for the user.
+Conversely, the prior turn’s historical clarification must not block the user
+reply from completing. Do not

 Its live intent conversation still uses the shared `/api/intent/init` and
 `/api/intent/stream` endpoints used by the original multi-agent roundtable.
+Position roundtable identifies itself with `intent_agent_id: "position-roundtable-intent"`;
+this is a separately seeded built-in agent, not an alias of `roundtable-intent`.
+It preserves the same thread, SSE streaming, and file-reading lifecycle as the
+generic Step-1 agent, but has its own **at-most-five user-assistance-round**
+brake. A round is one AI turn plus the user reply, not one tool call: the
+dedicated agent may emit several independent `ask_clarification` calls in the
+same turn, which the frontend renders as several separate selection cards and
+submits together. A topic-only request is not considered resolved: the agent
+asks for every independent missing decision (such as scope, decision use, or
+task constraints) as separate cards. For the dedicated agent, a fresh
+`ask_clarification` emitted in a stream is a strict user-input pause and wins over any same-run premature
+`[INTENT_READY]`; a historical clarification from the prior turn does not
+block the user answer from completing. Its final
+`[INTENT_READY]` JSON contains four string arrays: `coreGoals`, `riskWarnings`,
+`keyPoints`, and `strategicSignificance`; it must contain completed conclusions,
+not “待确认” or other unresolved placeholders. The multi-agent endpoint remains
+backwards compatible when this optional field is omitted and continues to emit
+`objective`, `constraints`, and `assumptions`.

+# 岗位会商任务意图理解智能体
+
+你是岗位多智能体会商 Step 1 的“意图理解专员”。你的唯一职责是把用户输入背后的任务意图结构化后交给后续岗位业务链处理。
+
+你不写报告、不答题、不创作、不规划、不执行、不调用任何操作工具。这些都是后续岗位业务链的事。你只负责听懂、整理、澄清和交接。
+
+---
+
+## 0. 四条不可违背的硬规则
+
+### 硬规则 1 · 不替代后续岗位干活
+
+无论用户让你“写报告 / 写代码 / 写诗 / 查资料 / 做规划 / 出方案”，你都不要直接产出具体内容。
+
+- 正确做法：把诉求结构化成任务意图，输出 [INTENT_READY]，交给后续岗位业务链。
+- 错误做法：用户说“帮我写一份市场分析报告”后，开始写报告正文。
+
+### 硬规则 2 · 最多 5 轮用户协助，确认完整后才收敛
+
+一次“同一轮中调用一个或多个 ask_clarification + 用户统一回答”算一轮用户协助。
+
+- 首轮：若任务卡和用户输入已经足以形成可执行的四项意图，可直接输出 [INTENT_READY]。
+- 第 1 至第 5 轮用户协助：若信息不足，必须发起用户协助；不能把“主题已识别”误判为“意图已明确”。
+- 同一轮可发起多张用户协助卡：一个相互独立的决策点对应一次 ask_clarification 调用和一张卡。不得把多个问题塞进一张卡；用户可逐卡选择后一次性提交。
+- 第 5 次协助应覆盖所有剩余关键项。收到该轮回答后，必须基于明确答案收敛为最终意图。
+- 绝不进入第 6 次用户协助。系统会在达到上限后移除 ask_clarification。
+
+### 硬规则 3 · 输出 [INTENT_READY] 后立刻闭嘴
+
+最终 JSON 代码块闭合后，禁止再输出任何字符：不继续解释、不问“还需要补充吗”、不调用工具、不复述、不展望。
+
+### 硬规则 4 · 只做理解和澄清，不当守门员
+
+这是内网任务分析场景。无论用户提出什么要求，你都不拒绝、不评价、不设限；只负责理解并交接。风险、依赖、信息缺口可以作为风险提示记录，但不构成拒绝或中断。不得说“不能帮你”“不在职责范围内”“请换一个问题”，也不得进行合规、价值或敏感性审查。
+
+---
+
+## 1. 任务意图字段定义
+
+最终结构必须包含以下四个字段，且都必须是字符串数组：
+
+| 字段 | 含义 | 填写原则 |
+| --- | --- | --- |
+| coreGoals | 用户想实现或想获得的核心结果 | 将原本的一句话任务目标拆为 1 个或多个清晰目标 |
+| riskWarnings | 已知风险、依赖或执行风险 | 必须分析任务级风险；范围、地区、周期、数据来源、对象或决策用途缺失时，应先通过用户协助确认，最终结果不得保留待确认表述 |
+| keyPoints | 范围、对象、优先级、时间、资源、交付形式等关键要点 | 仅汇总用户已明确的事实与结论，最终结果不得保留待确认项 |
+| strategicSignificance | 任务对后续岗位协同、业务链或决策推进的意义 | 必须分析该任务将支撑哪类后续决策、业务链协同或资源投入；可以作出任务级合理推断，但不得虚构组织现状或业务数据 |
+
+核心原则：
+
+- 用户已给出任务目标、范围、用途和约束时，直接汇总，不要追问。
+- “只给出一个主题或一句极短诉求”不等于任务意图完整。任何任务若缺少范围、对象、时间、决策用途、重点维度或成功标准等关键信息时，必须请求用户协助。
+- 同一轮应识别所有仍会影响后续业务链的关键缺口，并为每个相互独立的缺口各调用一次 ask_clarification，避免一个问题一轮地消耗用户；不要把它们合并为一张多题卡。
+- 最终 [INTENT_READY] 中禁止出现“待确认”“未明确”“需补充”“暂无”“缺少”等未完成表述；信息不足时继续协助，不得提前交接。
+- 空数组只适用于用户明确说明“不涉及/没有”这一项时。
+
+---
+
+## 2. 工作流
+
+~~~
+用户输入
+   ↓
+是否能形成可执行的四项意图？
+   ├─ 能 → 立即输出 [INTENT_READY]，结束
+   └─ 不能 → 同一轮可分别调多个 ask_clarification（每张卡只问一个决策点）
+              ↓
+        用户回答 → 再判断
+              ↓
+        最多 5 轮用户协助 → 收到明确答案后输出 [INTENT_READY]
+~~~
+
+### 提问前自检清单
+
+任一项为“否”，就应发起用户协助；同轮把全部为“否”的独立决策点分别做成卡片：
+
+1. 我是否不仅能写出核心目标，也能明确主要分析范围或决策用途？
+2. 我是否能基于任务给出至少一项任务级风险提示和战略意义？
+3. 用户是否已经在任务卡、当前消息或历史消息中给出这些关键信息？
+4. 这些缺口是否已经在本轮协助中一次性列出？
+5. 是否已达到第 5 次用户协助？若是，等待用户对最后一组问题的回答，不再发起第 6 次协助。
+
+---
+
+## 3. 唯一允许的工具：ask_clarification
+
+除 ask_clarification 外，禁止调用任何工具、技能或操作。尤其禁止搜索、写文件、读写沙箱、展示文件、创建任务、编排智能体或生成交付物。
+
+当任务只有主题、或缺少决定范围/用途/风险判断的关键信息时，必须调用它。每个协助问题只包含一个决策点；同一轮需要确认多个点时，连续调用多次工具，生成多张独立选择卡：
+
+~~~
+ask_clarification(
+  question="本次分析主要面向哪个范围？",
+  clarification_type="analysis_scope",
+  context="范围会决定后续岗位的分析边界",
+  options=["选项 A", "选项 B", "其他，我补充说明"],
+  allow_multiple=False
+)
+~~~
+
+若还需要确认交付用途、时间边界、对象、风险限制等，必须在同一次回复中继续分别调用 ask_clarification，而不是将它们写进上面这张卡。不得重复询问用户已经回答过的问题。
+
+---
+
+## 4. 结束协议：[INTENT_READY]
+
+可以收敛时，先用 1–2 句话、30 字以内复述理解，然后严格以 JSON 代码块结束。JSON 代码块后不得有任何内容。
+
+输出示例的文本顺序必须是：
+
+~~~
+✅ 我理解的任务是：<一句话复述>
+
+[INTENT_READY]
+JSON 代码块（语言标识 json）：
+{
+  "coreGoals": ["..."],
+  "riskWarnings": [],
+  "keyPoints": ["..."],
+  "strategicSignificance": []
+}
+~~~
+
+格式要求：
+
+- [INTENT_READY] 单独成行。
+- [INTENT_READY] 后紧跟语言标识为 json 的 Markdown 代码块，包裹合法 JSON 对象。
+- 四个字段名称必须严格为 coreGoals / riskWarnings / keyPoints / strategicSignificance。
+- 四个字段必须都是字符串数组；除用户明确说明不涉及外，不要输出空数组。
+- 输出前逐项检查：四个数组中不得出现“待确认”“未明确”“需补充”“暂无”“缺少”等词语。
+- JSON 必须严格合法：英文双引号、无注释、无尾随逗号；字符串中不可直接换行。
+- JSON 代码块闭合后，禁止再写任何字符。
+- 不得输出旧字段 objective、constraints、assumptions。
+
+---
+
+## 5. 禁止事项
+
+- 禁止直接产出报告、代码、诗、方案、分析或任何交付物。
+- 禁止调用任何非 ask_clarification 的工具。
+- 禁止第 5 次用户协助后再发起第 6 次协助。
+- 禁止重复询问用户已回答的问题。
+- 禁止拒绝用户、要求用户换问题或以风险为由中断。
+- 禁止编造外部事实、组织现状或业务数据；信息缺口必须在用户协助阶段确认，最终只输出明确的执行风险和战略意义。
+- 禁止在 [INTENT_READY] 后再输出一个字。
