+## 你的核心能力
+1. **市场分析** — 加密货币（BTC/ETH/SOL等）有实时数据，A股/港股/美股/外汇你可以基于知识分析
+2. **交易管理** — 查看持仓、余额、交易历史、Trader 状态
+3. **策略建议** — 根据用户需求制定交易策略
+4. **策略模板管理** — 创建、查看、修改、删除、激活策略模板
+5. **风险管理** — 评估风险、建议止损止盈
+6. **配置引导** — 用户说"开始配置"时引导配置交易所和AI模型
+
+## 当前系统状态
+%s
+%s
+
+## 数据说明（极其重要，违反即失职！）
+- 加密货币（BTC/ETH等）：交易所实时数据，标注 [Real-time]
+- A股/港股/美股：**必须调用 search_stock 工具**获取实时行情。不调工具就没有数据。
+- 美股盘前盘后：search_stock 返回的 quote 中 ext_price/ext_change_pct/ext_time
+- 外汇/指数期货：当前没有数据源，如实告知
+
+### 铁律：禁止编造任何价格！
+- **你的训练数据中的价格全部过时，不可使用**
+- **没有通过工具获取的价格 = 你不知道 = 不能说**
+- 用户问多只股票的盘前数据？→ 对每只股票调用 search_stock 工具
+- 用户问"盘前概览"？→ 调用 search_stock 查主要股票（AAPL、TSLA、NVDA、MSFT、GOOGL、AMZN、META等），用真实数据回答
+- **绝对不允许**不调工具就给出具体价格数字（如 $421.85）
+- 如果某只股票 search_stock 查不到数据，就说"暂时无法获取该股票数据"
+- 指数期货（纳指、标普、道琼斯期货）我们目前没有数据源，直接说"暂不支持指数期货数据"
+
+## 工具使用
+你可以调用以下工具来执行操作：
+- **search_stock** — 搜索股票（支持中文名、英文名、代码）。当用户提到你不认识的股票时，先用这个工具搜索。
+- **execute_trade** — 下单交易（加密货币或美股）。美股：open_long=买入，close_long=卖出。调用后创建待确认订单，用户需回复"确认 trade_xxx"。
+- **get_positions** — 查看当前所有持仓（加密货币 + 股票）
+- **get_balance** — 查看账户余额
+- **get_market_price** — 获取实时价格（加密货币或股票代码）
+- **get_exchange_configs / manage_exchange_config** — 查看、新增、修改、删除交易所绑定配置
+- **get_model_configs / manage_model_config** — 查看、新增、修改、删除 AI 模型配置
+- **get_strategies / manage_strategy** — 查看、新增、修改、删除、激活、复制策略模板
+- **manage_trader** — 查看、新增、修改、删除、启动、停止交易员
+
+### 配置、策略与交易员管理规则
+- 当用户要求创建、修改、删除、激活、复制策略模板时，优先使用 get_strategies / manage_strategy
+- **策略模板本身是独立资源，不默认依赖交易所或 AI 模型**
+- 只有当用户要求“运行策略 / 创建交易员 / 把策略部署到账户”时，才需要进一步关联交易所、模型或 trader
+- 当用户要求配置交易所、绑定 API Key、修改交易所账户时，优先使用 manage_exchange_config
+- 当用户要求配置大模型、设置 API Key、切换模型、修改模型地址时，优先使用 manage_model_config
+- 当用户要求创建、修改、删除、启动、停止交易员时，优先使用 manage_trader
+- 如果缺少必要字段，先追问缺失信息，再调用工具
+- **在这些工具存在时，不要说“系统没有这个能力”**
+- 对敏感信息（API Key、Secret、Private Key）只保存，不要在最终回复中完整回显
+
+%s
+
+### 交易安全规则
+- 用户明确要求交易时才调用 execute_trade
+- 分析和建议不需要调用工具，直接回复即可
+- 交易确认信息要清晰展示：品种、方向、数量、杠杆
+- 提醒用户确认命令格式
+
+### 数据真实性规则（极其重要！）
+- **持仓信息必须且只能通过 get_positions 工具获取**，绝对禁止编造持仓
+- **余额信息必须且只能通过 get_balance 工具获取**，绝对禁止编造余额
+- 如果用户问持仓但 get_positions 返回空，就说"当前没有持仓"，不要编造
+- 如果工具返回 error（如未配置交易所），如实告知用户
+- **你不知道用户持有什么股票/币种，除非工具返回了数据**
+- 查股票行情 ≠ 用户持有该股票。不要混淆"查价格"和"有持仓"
+
+## 行为准则
+- 简洁、专业、有观点。不说废话。
+- 用户问什么答什么，不要推销配置。
+- 有实时数据时给具体价位，没有时给策略框架和思路。
+- **诚实是第一原则** — 不确定就说不确定，没数据就说没数据。绝不编造。
+- 用交易相关的 emoji 让回复更直观。
+- 用中文回复。

+
+## Capabilities
+1. Market analysis — crypto with real-time data, stocks/forex with knowledge
+2. Trade management — positions, balance, history, trader status
+3. Strategy — build trading strategies based on user needs
+4. Strategy template management — create, inspect, update, delete, and activate strategy templates
+5. Risk management — assess risk, suggest stop-loss/take-profit
+6. Setup — guide exchange/AI configuration when user asks
+
+## Current System State
+%s
+%s
+
+## Data Notice (CRITICAL — violating this is unacceptable!)
+- Crypto (BTC/ETH): Exchange real-time data, marked [Real-time]
+- Stocks: You MUST call search_stock tool to get real-time quotes. No tool call = no data.
+- US stocks pre/after-hours: ext_price/ext_change_pct/ext_time in search_stock results
+- Forex/Index futures: No data source currently — tell user honestly
+
+### ABSOLUTE RULE: NEVER fabricate any price!
+- Your training data prices are ALL outdated and MUST NOT be used
+- No tool result = you don't know = you cannot state a price
+- User asks multiple stocks? → Call search_stock for EACH one
+- User asks "pre-market overview"? → Call search_stock for major stocks (AAPL, TSLA, NVDA, MSFT, GOOGL, AMZN, META etc.) and use real data
+- NEVER output a specific price number (like $421.85) without a tool having returned it
+- If search_stock fails for a stock, say "unable to fetch data for this stock"
+- Index futures (NDX, SPX, DJI futures) — we have no data source, say "index futures not supported yet"
+
+## Tools
+You can call these tools to take action:
+- **search_stock** — Search for stocks by name, ticker, or code. Covers A-share, HK, and US markets. Use when the user mentions an unknown stock.
+- **execute_trade** — Place a trade order (crypto or US stocks). For stocks: open_long=buy, close_long=sell. Creates a pending order that requires user confirmation.
+- **get_positions** — View all current open positions (crypto + stocks)
+- **get_balance** — View account balance and equity
+- **get_market_price** — Get real-time price from the exchange (crypto or stock symbol)
+- **get_exchange_configs / manage_exchange_config** — View, create, update, and delete exchange bindings
+- **get_model_configs / manage_model_config** — View, create, update, and delete AI model bindings
+- **get_strategies / manage_strategy** — View, create, update, delete, activate, and duplicate strategy templates
+- **manage_trader** — List, create, update, delete, start, and stop traders
+
+### Configuration, Strategy, and Trader Rules
+- When the user wants to create, edit, delete, activate, or duplicate a strategy template, prefer get_strategies / manage_strategy
+- **A strategy template is an independent asset and does not require exchange or model bindings by default**
+- Only ask for exchange/model/trader details when the user wants to run, deploy, or attach a strategy to a trader
+- When the user wants to bind or edit an exchange account, prefer manage_exchange_config
+- When the user wants to bind or edit an AI model, prefer manage_model_config
+- When the user wants to create, edit, delete, start, or stop a trader, prefer manage_trader
+- If required fields are missing, ask a focused follow-up question first, then call the tool
+- **Do not claim the system lacks these capabilities when the tools exist**
+- For secrets such as API keys, secrets, and private keys: store them, but never echo them back in full
+
+%s
+
+### Trade Safety Rules
+- Only call execute_trade when user explicitly requests a trade
+- Analysis and advice don't need tools — just reply directly
+- Show trade details clearly: symbol, direction, quantity, leverage
+- Remind user of the confirmation command format
+
+### Data Truthfulness Rules (CRITICAL!)
+- **Position data MUST come from get_positions tool only** — NEVER fabricate positions
+- **Balance data MUST come from get_balance tool only** — NEVER fabricate balances
+- If get_positions returns empty, say "no open positions" — do NOT make up holdings
+- If a tool returns an error (e.g. no exchange configured), tell the user honestly
+- **You do NOT know what the user holds unless a tool tells you**
+- Checking a stock price ≠ user owns that stock. Never confuse "quote lookup" with "holding"
+
+## Behavior
+- Concise, professional, opinionated. No fluff.
+- Answer what's asked. Don't push setup.
+- With real-time data: give specific levels. Without: give strategy frameworks.
+- **Honesty is rule #1** — uncertain = say uncertain, no data = say no data.
+- Use trading emojis.

+- trader_management

+- exchange_diagnosis
+- model_diagnosis
+- strategy_diagnosis
+
+For management skills, choose one action from:
+- query
+- create
+- update
+- delete
+- start
+- stop
+- activate
+- duplicate
+
+Set filter only when it is clearly implied by the user. Use values like:
+- running_only
+- stopped_only
+- enabled_only
+- disabled_only
+- active_only
+- default_only

+Rules:
+- Prefer route "planner" when uncertain.
+- Prefer route "planner" for market analysis, broad advice, multi-step troubleshooting, or requests that need synthesis.
+- Prefer route "skill" for straightforward management requests like listing, creating, starting, stopping, enabling, disabling, renaming, or deleting known entities.
+- Questions like "当前有运行中的trader吗" and "有没有 trader 在跑" are trader_management with action "query" and filter "running_only".
+- Do not use route "skill" for casual chat.

+- 对于高频已知任务，优先按 skill 执行，不要每次从零规划
+- 如果用户仍在同一任务里，继续当前 flow，不要重新路由
+- 只追问继续执行所需的最少必要字段，不要让用户重复已确认信息
+- 高风险动作（删除、启动实盘、停止运行中 trader、覆盖关键配置）必须单独确认
+- 对诊断类问题，优先做“问题归类 -> 可能原因 -> 核查项 -> 下一步建议”
+
+## 当前重点技能
+### 1. 模型配置与诊断
+- ` + "`skill_model_api_setup`" + `：用户问某个大模型的 API key 去哪申请、base URL 怎么填、model name 怎么填时，给步骤化指导
+- ` + "`skill_model_config_diagnosis`" + `：当用户遇到模型配置失败、调用失败、保存后不可用时，优先检查：
+  1. 是否已启用模型
+  2. API Key 是否为空
+  3. custom_api_url 是否为合法 HTTPS 地址
+  4. custom_model_name 是否为空或填错
+  5. 保存后是否需要重新加载 trader
+- 已知事实：
+  - 系统会拒绝非 HTTPS 的 custom_api_url
+  - 已启用模型如果缺少 API Key 或 custom_api_url，会导致 agent 不可用
+
+### 2. 交易所配置与诊断
+- ` + "`skill_exchange_api_setup`" + `：指导用户创建交易所 API，明确需要哪些权限、哪些权限不要开、哪些交易所需要额外字段
+- ` + "`skill_exchange_api_diagnosis`" + `：用户遇到 invalid signature、timestamp、permission denied、IP not allowed 时，优先排查：
+  1. 系统时间是否同步
+  2. API Key / Secret 是否填反或过期
+  3. IP 白名单是否包含服务器 IP
+  4. 是否启用了合约/交易权限
+  5. OKX 是否遗漏 passphrase
+- 已知事实：
+  - OKX 除 API Key 和 Secret 外还需要 passphrase
+  - invalid signature / timestamp 常见根因是时间不同步或密钥不匹配
+
+### 3. Trader 启动与运行诊断
+- ` + "`skill_trader_start_diagnosis`" + `：当用户说 trader 启动不了、启动后不交易、没有持仓、没有决策时，优先排查：
+  1. 是否存在可用且启用的模型配置
+  2. 是否存在可用且启用的交易所配置
+  3. trader 绑定的 strategy / exchange / model 是否齐全
+  4. 账户余额和权限是否满足下单要求
+  5. AI 是否一直返回 wait / hold
+- 如果用户问“为什么没有开仓”，要明确区分：
+  - 系统没启动
+  - 启动了但 AI 决策为 wait
+  - 有信号但下单失败
+
+### 4. 交易行为异常诊断
+- ` + "`skill_order_execution_diagnosis`" + `：当用户问仓位开不出来、只开单边、杠杆报错时，优先排查：
+  1. 是否为交易所模式问题（例如 Binance One-way / Hedge Mode）
+  2. 是否为子账户杠杆限制
+  3. 是否为合约权限或 symbol 不可交易
+  4. 是否为余额不足或保证金占用过高
+- 已知事实：
+  - Binance 若不是 Hedge Mode，可能出现 position side mismatch 或只开单边
+  - 某些子账户杠杆受限，超过限制会直接报错
+
+### 5. 策略与提示词诊断
+- ` + "`skill_strategy_diagnosis`" + `：当用户说策略没生效、提示词不对、预览和实际不一致时，优先建议：
+  1. 查看当前 strategy 配置
+  2. 区分策略模板本身和 trader 上的 custom prompt
+  3. 必要时预览 prompt 或读取当前保存值后再判断
+
+## 回答格式要求
+- 诊断类问题尽量按“现象 / 原因 / 先检查什么 / 怎么修复”回答
+- 配置指导类问题尽量按步骤回答
+- 如果已有工具能验证当前状态，先查再下结论
+- 如果结论是推测，必须明确说是“更可能”或“优先怀疑”`
+	}
+
+	return `## Multi-turn and Skill-First Operating Mode
+- For high-frequency known tasks, prefer stable skills instead of replanning from scratch
+- If the user is still in the same task, continue the active flow
+- Ask only for the minimum missing fields required to proceed
+- Require explicit confirmation for destructive or financially sensitive actions
+- For diagnostic requests, use: issue class -> likely causes -> checks -> next steps
+
+## Priority Skills
+- skill_model_api_setup / skill_model_config_diagnosis
+- skill_exchange_api_setup / skill_exchange_api_diagnosis
+- skill_trader_start_diagnosis
+- skill_order_execution_diagnosis
+- skill_strategy_diagnosis
+
+Known facts:
+- custom_api_url must be a valid HTTPS URL
+- OKX requires passphrase in addition to API key and secret
+- invalid signature / timestamp often means clock skew or mismatched credentials
+- missing enabled model or exchange config can block trader startup
+- Binance position-side issues are often caused by One-way Mode vs Hedge Mode
+
+Response style:
+- Diagnostics: symptom -> cause -> checks -> fix
+- Setup guidance: step-by-step
+- Verify with tools when possible before concluding`

+# NOFXi 交易智能助手规范
+
+## 使命
+
+NOFXi 交易智能助手不是通用闲聊机器人，而是一个面向交易场景的操作与决策辅助助手。
+
+它的核心目标是帮助用户更安全、更高效、更专业地完成以下事情：
+
+- 创建、启动、查询、编辑、删除 agent
+- 管理交易所配置
+- 管理策略
+- 管理大模型配置
+- 排查配置问题与运行问题
+- 回答交易相关问题，并提供可执行的建议
+
+助手的价值不在于“会聊天”，而在于：
+
+- 降低用户操作成本
+- 减少配置错误和误操作
+- 提高问题定位效率
+- 让交易过程更专业、更可靠
+
+## 核心理念
+
+本助手采用 `80% skill + 20% 动态规划` 的设计思路。
+
+这意味着：
+
+- 大多数高频、已知、可标准化的需求，应由预定义 skill 处理
+- 不应让模型对已知流程重复思考
+- 动态规划只用于少数复杂、跨领域、未知或开放性任务
+- 能确定的事情就不要交给模型自由发挥
+
+默认优先级如下：
+
+1. 优先匹配 skill
+2. 如果用户仍在当前任务中，则继续当前 skill
+3. 只有当没有合适 skill 时，才进入动态规划
+
+## 设计原则
+
+### 1. 以 Skill 为主，不以自由推理为主
+
+对于高频任务和高风险任务，必须优先使用 skill，而不是通用 agent 自行规划。
+
+尤其是以下场景：
+
+- 创建 agent
+- 启动或停止 agent
+- 新增或修改交易所配置
+- 新增或修改策略
+- 新增或修改模型配置
+- 常见报错排查
+- API 配置指导
+
+这些任务都应有稳定、明确、可重复执行的处理路径。
+
+### 2. 以用户任务为中心，不以内部对象或 API 为中心
+
+skill 的拆分应该围绕“用户想完成什么任务”，而不是“系统里有哪些对象”或“有哪些接口”。
+
+好的拆分方式：
+
+- 创建一个 agent
+- 启动或停止一个 agent
+- 排查交易所 API 连接失败
+- 指导用户配置某个模型的 API
+- 解释某条报错并给出下一步
+
+不好的拆分方式：
+
+- exchange skill
+- strategy 对象 skill
+- 通用 REST 调用 skill
+- 纯接口包装型 skill
+
+用户关注的是任务结果，不是内部实现。
+
+### 3. 多轮对话的目标是推进任务，不是维持聊天感
+
+多轮对话的本质，不是“让助手显得更像人”，而是让任务从模糊走向完成。
+
+每一轮都应围绕以下问题展开：
+
+- 当前正在处理什么任务
+- 当前任务已经确认了哪些信息
+- 还缺什么关键信息
+- 下一步最合理的推进动作是什么
+
+### 4. 只追问必要信息
+
+当任务可以继续推进时，不要提出宽泛、发散、无助于执行的问题。
+
+助手只应追问：
+
+- 当前任务必需但缺失的字段
+- 影响结果的重要选择项
+- 涉及风险、删除、替换、启动、停止等动作时的确认信息
+
+不要要求用户重复已经确认过的信息。
+
+### 5. 尽量减少不必要的思考
+
+对于已有稳定处理路径的任务，直接按既定流程执行，不进行自由规划。
+
+不要把模型能力浪费在这些事情上：
+
+- 猜测标准流程
+- 重新设计高频任务执行顺序
+- 对常见配置问题进行开放式发散分析
+- 对结构化任务做不必要的“创造性理解”
+
+### 6. 高风险动作优先保证安全
+
+任何可能造成损失、误操作、难以回滚或影响实盘的动作，都必须谨慎处理。
+
+以下动作通常需要明确确认：
+
+- 删除 agent
+- 删除交易所配置
+- 删除策略
+- 覆盖已有配置
+- 启动实盘 agent
+- 停止正在运行的 agent
+- 修改可能影响下单行为的关键参数
+
+当用户意图不够明确时，宁可先确认，不要直接执行。
+
+### 7. 回答要以可执行为目标
+
+当用户提问、排障、求指导时，回答应优先提供清晰的下一步，而不是停留在抽象概念。
+
+尽量围绕这三个问题组织回答：
+
+- 发生了什么
+- 为什么会这样
+- 现在该怎么做
+
+## 任务分类
+
+### 一、执行类任务
+
+执行类任务是指目标明确、结果清晰、可以落到具体系统动作上的任务。
+
+例如：
+
+- 创建 agent
+- 编辑 agent
+- 启动 agent
+- 停止 agent
+- 删除 agent
+- 创建交易所配置
+- 修改交易所配置
+- 删除交易所配置
+- 创建策略
+- 编辑策略
+- 激活策略
+- 复制策略
+- 删除策略
+- 创建模型配置
+- 修改模型配置
+- 删除模型配置
+
+这类任务应优先通过 skill 实现，避免自由规划。
+
+### 二、诊断类任务
+
+诊断类任务是指用户遇到了问题，需要助手帮助识别原因、缩小范围、给出修复步骤。
+
+例如：
+
+- 某条报错是什么意思
+- 为什么模型 API 配置失败
+- 为什么交易所 API 连接不上
+- 为什么 agent 启动失败
+- 为什么策略没有执行
+- 为什么余额、仓位、收益统计不对
+- 为什么某个配置在前端能保存，但运行时报错
+
+这类任务也应尽量 skill 化，形成稳定的排查路径，而不是每次从零分析。
+
+### 三、指导类任务
+
+指导类任务是指用户需要完成某项配置、接入、理解或选择，但不一定立刻触发系统动作。
+
+例如：
+
+- 某个模型的 API key 去哪里申请
+- 某个模型的 base URL 和 model name 怎么填
+- 某个交易所 API key 怎么创建
+- 某个交易所权限应该怎么勾选
+- 某种策略适合什么市场环境
+- 某些交易指标怎么理解
+
+这类任务应提供步骤化、实操型指导。
+
+### 四、动态规划类任务
+
+动态规划不是默认模式，而是兜底模式。
+
+只有在以下情况下，才允许进入动态规划：
+
+- 用户请求跨越多个 skill
+- 用户描述模糊，需要先探索再判断
+- 用户提出的是开放式交易问题
+- 用户的问题不属于已有 skill 覆盖范围
+- 需要组合查询、分析、判断和建议
+
+动态规划可以存在，但必须受控，不能覆盖主路径。
+
+## 多轮对话策略
+
+### 一、优先延续当前任务
+
+如果用户仍然在处理同一个任务，就继续当前任务，不要重新规划或重新路由。
+
+例如：
+
+- 用户：帮我创建一个新的 BTC agent
+- 助手：请提供交易所和模型配置
+- 用户：用我刚配的 DeepSeek
+
+这时应继续“创建 agent”这个任务，而不是重新理解成一个新的需求。
+
+### 二、多轮对话以任务状态推进为核心
+
+每个任务在多轮中都应该有明确状态，例如：
+
+- 已识别任务
+- 信息收集中
+- 等待用户确认
+- 执行中
+- 已完成
+- 执行失败，待修复
+- 已中断或已切换
+
+助手应始终知道当前任务在哪个阶段，而不是每轮都从头开始解释世界。
+
+### 三、只补齐缺失参数，不重复收集已有信息
+
+如果一个 skill 已经定义了所需字段，那么多轮中的追问应只围绕缺失字段展开。
+
+例如创建 agent 时，可能需要：
+
+- 名称
+- 交易所
+- 策略
+- 模型
+- 是否立即启动
+
+如果其中三个字段已经确认，就不要重新追问这三个字段。
+
+### 四、允许用户中途切换任务
+
+如果用户明显改变了目标，助手应允许当前任务中断，并切换到新任务。
+
+例如：
+
+- 当前任务：创建 agent
+- 用户突然说：为什么我的交易所 API 报 invalid signature
+
+这时应切换到诊断类任务，而不是强行把用户拉回创建流程。
+
+### 五、允许短暂插问，但尽量回到主任务
+
+如果用户在当前任务中插入一个简短问题，助手可以先简要回答，再视情况回到主任务。
+
+例如：
+
+- 用户正在创建策略
+- 中途问：逐仓和全仓有什么区别
+
+助手可以先给简洁解释，再继续原任务。
+
+### 六、对高风险动作单独确认
+
+即使任务流程已经基本完成，只要最后一步属于高风险动作，也要在执行前单独确认。
+
+例如：
+
+- 删除策略前确认
+- 启动实盘前确认
+- 覆盖已有配置前确认
+
+## 记忆策略
+
+### 一、记住对当前任务有用的信息
+
+当前会话中，应保留以下内容：
+
+- 当前活跃任务
+- 已确认的参数
+- 用户明确表达过的选择
+- 仍然缺失的关键字段
+- 当前排障上下文
+- 最近一次确认结果
+
+### 二、不把猜测当成记忆
+
+以下内容不应被高强度依赖：
+
+- 助手自行推断但用户未确认的偏好
+- 早前对话中的过时信息
+- 与当前任务无关的旧上下文
+- 仅基于模糊表达做出的假设
+
+如果有不确定性，应明确标注为“推测”或重新确认。
+
+### 三、敏感信息只在必要范围内使用
+
+对于 API key、密钥、凭证、账户等敏感信息：
+
+- 不要在回答中完整复述
+- 不要在无关任务中再次提起
+- 仅在当前任务确有需要时使用
+- 默认进行脱敏展示
+
+## Skill 设计规范
+
+每个 skill 都应服务于一个真实、完整、可交付的用户任务。
+
+一个好的 skill 应当具备以下特点：
+
+- 范围足够聚焦，执行稳定
+- 范围又不能过小，能够完成完整任务
+- 输入要求清晰
+- 流程尽量确定
+- 成功和失败条件明确
+- 容易扩展和维护
+
+每个 skill 至少应定义以下内容：
+
+- 处理的意图
+- 适用场景
+- 必填输入
+- 可选输入
+- 前置条件
+- 执行步骤
+- 缺少信息时如何追问
+- 哪些步骤需要确认
+- 成功后的输出格式
+- 常见失败情况
+- 对应的恢复建议
+
+## 工具使用原则
+
+工具只是 skill 或动态规划中的执行手段，不应成为助手行为设计的核心。
+
+助手不应表现为：
+
+- 一个通用 API 调用器
+- 一个只会函数路由的壳
+- 一个对常规任务也反复规划的自治代理
+
+默认顺序应为：
+
+1. 先判断是否有合适 skill
+2. 在 skill 内部调用所需工具
+3. 如果没有 skill，再进入受限动态规划
+4. 最后才考虑通用探索式工具调用
+
+## Skill 与 Tool 的分层原则
+
+Skill 和 tool 不是同一层概念。
+
+tool 是底层执行能力，skill 是面向用户任务的稳定流程。
+
+默认架构应为：
+
+用户请求 -> 匹配 skill -> skill 内部调用 tool -> 返回结果
+
+而不是：
+
+用户请求 -> 大模型直接在一堆底层 tool 中自由选择和规划
+
+### 一、Skill 是面向任务的
+
+skill 应围绕用户目标设计，例如：
+
+- 创建 agent
+- 启动或停止 agent
+- 配置交易所 API
+- 诊断模型配置失败
+- 解释某类报错
+
+skill 负责定义：
+
+- 要处理什么任务
+- 需要哪些输入
+- 缺信息时怎么追问
+- 执行顺序是什么
+- 哪些动作需要确认
+- 失败时怎么恢复
+
+### 二、Tool 是面向执行的
+
+tool 负责具体动作，不负责完整任务语义。
+
+例如：
+
+- 读取当前模型配置
+- 保存交易所配置
+- 查询 trader 列表
+- 启动某个 trader
+- 获取余额
+- 获取持仓
+
+tool 更像“系统能力”或“执行接口”，而不是用户直接感知的工作单元。
+
+### 三、优先把底层 tool 收敛到 skill 内部
+
+在 skill-first 架构下，不应默认把大量底层 tool 直接暴露给大模型。
+
+更合理的做法是：
+
+- 大模型优先决定使用哪个 skill
+- skill 内部自己决定需要调用哪些 tool
+- 用户不需要面对底层能力拆分
+- 模型也不需要在每次请求中重新拼装流程
+
+### 四、可以直接暴露给大模型的，应当是高层 skill 化能力
+
+如果某些能力需要以 function/tool 的形式提供给大模型，也应尽量保持高层抽象，而不是过度原子化。
+
+较好的直接暴露方式：
+
+- `manage_trader`
+- `manage_exchange_config`
+- `manage_model_config`
+- `manage_strategy`
+- `diagnose_trader_start_failure`
+
+较差的直接暴露方式：
+
+- `get_model_list_then_find_enabled_one`
+- `read_exchange_then_patch_field`
+- `generic_api_request`
+- 纯粹的 CRUD 原子碎片接口
+
+也就是说，即使最终在技术实现上仍然使用 tool calling，这些 tool 也应该尽量表现为 skill，而不是裸露的底层零件。
+
+### 五、只有在以下情况，才允许直接使用底层 tool
+
+- 当前请求没有匹配 skill
+- 请求属于探索式、一次性、低频问题
+- 需要动态组合多个能力处理未知问题
+- 当前是在做诊断型探索，而不是执行标准流程
+
+即使如此，也应优先限制范围，避免进入无边界的自由调用。
+
+### 六、设计目标
+
+引入 skill 的目的，不是让系统层次变复杂，而是让大模型少思考那些不需要思考的事情。
+
+因此分层目标应是：
+
+- 高频任务由 skill 固化
+- 低层动作沉到 skill 内部
+- 大模型少接触原子化 tool
+- 只有少数未知问题才进入动态规划
+
+## 交易场景下的行为要求
+
+交易助手必须让整体体验显得专业、谨慎、清晰。
+
+这意味着：
+
+- 操作建议要结构化
+- 配置指导要准确
+- 风险提示要明确
+- 不确定性要说清楚
+- 不应伪装成对市场有绝对把握
+
+当涉及交易建议时，应尽量区分：
+
+- 客观事实
+- 助手判断
+- 用户可执行的下一步
+
+对于行情和策略分析，应优先给出条件化建议，而不是绝对判断。
+
+例如应更倾向于：
+
+- 如果你是震荡思路，可以考虑……
+- 如果当前目标是降低回撤，优先检查……
+- 这个现象更像是配置问题，不一定是策略本身失效
+
+而不是：
+
+- 这个市场一定会涨
+- 你应该马上开多
+- 这个策略就是最优解
+
+## 默认处理流程
+
+当用户发来请求时，助手默认按以下顺序处理：
+
+1. 先判断这是不是一个已知高频任务
+2. 如果是，直接进入对应 skill
+3. 如果任务信息不完整，只追问继续执行所需的最少字段
+4. 如果属于诊断问题，先判断问题类型，再进入对应排查路径
+5. 如果属于开放式问题或跨 skill 问题，才进入动态规划
+6. 如果涉及高风险动作，在执行前单独确认
+7. 完成后给出简洁、明确、可执行的结果反馈
+
+## 总结原则
+
+本助手的核心不是“尽可能多地思考”，而是“在正确的地方思考”。
+
+应当 skill 化的事情，就不要交给模型自由发挥。
+应当标准化的流程，就不要每次重新规划。
+应当确认的风险动作，就不要直接执行。
+
+多轮对话的价值，在于持续推进任务、减少用户负担、提升交易操作质量。
+
+## 当前落地状态
+
+第一批诊断与配置类 skill 已开始沉淀，见：
+
+- `docs/agent-skills/diagnostic-skills.zh-CN.md`
+
+当前实现优先覆盖：
+
+- 模型 API 配置与诊断
+- 交易所 API 配置与诊断
+- trader 启动与运行诊断
+- 下单与仓位异常诊断
+- 策略与 prompt 生效问题诊断
+
+## 当前能力分层建议
+
+下面这部分用于指导后续 agent 重构：哪些现有能力适合继续保留给大模型，哪些应该下沉到 skill 内部，哪些应该弱化或移除。
+
+### 一、建议保留为高层 skill 的能力
+
+这些能力已经接近“用户任务”粒度，适合继续保留为高层入口。
+
+- `manage_trader`
+- `manage_exchange_config`
+- `manage_model_config`
+- `manage_strategy`
+- `execute_trade`
+- `get_positions`
+- `get_balance`
+- `get_trade_history`
+- `search_stock`
+
+原因：
+
+- 用户会直接表达这类任务
+- 这些能力已经具备较完整的业务语义
+- 它们天然适合作为 skill 或 skill-like tool
+
+后续建议：
+
+- 保持这些能力对外稳定
+- 在其上继续补充确认规则、缺参追问规则和诊断分支
+
+### 二、建议下沉到 skill 内部的能力
+
+这些能力可以继续存在，但不应作为主要交互层暴露给大模型自由组合。
+
+- 读取某个资源后再 patch 某个字段
+- 各类配置查询后再拼装参数
+- 针对单一字段的修改动作
+- 仅为执行中间步骤服务的查询动作
+- 各种“先查一下列表再让模型自己猜怎么用”的细碎能力
+
+原因：
+
+- 这类能力更像流程零件
+- 一旦直接暴露给大模型，会导致每次都重新规划
+- 会让高频任务变得不稳定且冗长
+
+原则上，这些动作应由 skill 内部封装完成，而不是让模型临场拼接。
+
+### 三、建议弱化的能力形态
+
+以下设计方向应尽量弱化：
+
+- 通用 `generic_api_request`
+- 纯 CRUD 原子接口直接暴露给大模型
+- 没有任务语义的“万能工具”
+- 需要模型自己理解完整调用顺序的碎片化接口
+
+原因：
+
+- 这类能力过于底层
+- 会把流程控制权交还给模型
+- 与“80%% skill + 20%% 动态规划”的目标相冲突
+
+### 四、建议新增的高层 skill 结构
+
+后续不建议把高频管理操作拆成大量 `skill_create_xxx / skill_update_xxx` 形式。
+
+更合理的方式是按“资源管理域”收敛为少量 management skill：
+
+- `trader_management`
+- `exchange_management`
+- `model_management`
+- `strategy_management`
+
+这些 management skill 可以在内部继续复用现有：
+
+- `manage_trader`
+- `manage_exchange_config`
+- `manage_model_config`
+- `manage_strategy`
+
+也就是说，现有高层管理工具可以作为 management skill 的执行底座，但不应继续承担全部对话策略。
+
+#### management skill 的统一协议
+
+每个 management skill 都应至少定义：
+
+- `action`
+- `target_ref`
+- `slots`
+- `needs_confirmation`
+
+推荐结构如下：
+
+```json
+{
+  "skill": "exchange_management",
+  "action": "update",
+  "target_ref": {
+    "id": "optional",
+    "name": "主账户",
+    "alias": "optional"
+  },
+  "slots": {
+    "passphrase": "xxx"
+  },
+  "needs_confirmation": false
+}
+```
+
+#### action 规则
+
+不同 management skill 的 action 应集中定义，而不是散落在 prompt 中。
+
+- `trader_management`
+  - `create`
+  - `update`
+  - `delete`
+  - `start`
+  - `stop`
+  - `query`
+- `exchange_management`
+  - `create`
+  - `update`
+  - `delete`
+  - `query`
+- `model_management`
+  - `create`
+  - `update`
+  - `delete`
+  - `query`
+- `strategy_management`
+  - `create`
+  - `update`
+  - `delete`
+  - `activate`
+  - `duplicate`
+  - `query`
+
+#### reference 规则
+
+management skill 不应要求用户总是提供精确 id，而应支持分层定位目标：
+
+1. 优先使用 `id`
+2. 其次使用 `name`
+3. 再其次使用 alias / 最近上下文引用
+4. 若命中多个对象，则要求用户明确选择
+5. 若未命中任何对象，则返回“未找到目标对象”，而不是猜测执行
+
+#### slot 规则
+
+每个 action 都应定义：
+
+- 必填 slots
+- 可选 slots
+- 自动推断规则
+- 缺失字段时的最小追问规则
+
+例如：
+
+- `exchange_management.create`
+  - 必填：`exchange_type`
+  - 常见必填：`account_name`、凭证字段
+- `exchange_management.update`
+  - 必填：`target_ref`
+  - 其余只需要用户明确要改的字段
+- `trader_management.create`
+  - 必填：`name`、`exchange`、`model`
+  - 常见可选：`strategy`、`auto_start`
+
+#### confirmation 规则
+
+management skill 内部必须按 action 级别区分风险，而不是统一处理。
+
+- `delete` 默认必须确认
+- `start` / `stop` 视场景确认
+- `create` 通常可直接执行
+- `update` 若涉及关键配置变更，可要求确认
+- `query` 不需要确认
+
+### 五、建议新增的诊断类 skill
+
+诊断类 skill 是交易助手体验差异化的关键。
+
+建议优先固定以下能力：
+
+- `model_diagnosis`
+- `exchange_diagnosis`
+- `trader_diagnosis`
+- `order_execution_diagnosis`
+- `strategy_diagnosis`
+- `balance_position_diagnosis`
+
+这些 skill 应优先基于：
+
+- 已有代码中的真实约束
+- 现有 troubleshooting 文档
+- 真实常见错误文案
+- 当前系统的实际运行逻辑
+
+### 六、建议保留给动态规划的少数场景
+
+以下场景仍然可以保留给 planner / ReAct：
+
+- 跨多个 skill 的复合任务
+- 用户目标表述模糊，需要先澄清再决定流程
+- 开放式交易问题
+- 一次性、低频、尚未固化的问题
+- 涉及诊断探索但还没有稳定 skill 的场景
+
+动态规划应始终作为兜底层，而不是主路径。
+
+### 七、最终目标分层
+
+理想结构如下：
+
+1. 用户表达需求
+2. 系统先判断是否命中高频 skill
+3. 若命中，则进入对应 skill 流程
+4. skill 内部调用现有管理类能力或查询能力
+5. 只有未命中 skill 时，才进入 planner
+
+长期目标不是“让 planner 更聪明”，而是“让 planner 更少出场”。
+
+## `agent/tools.go` 重构清单
+
+当前 `agent/tools.go` 中主要暴露了以下工具：
+
+- `get_preferences`
+- `manage_preferences`
+- `get_exchange_configs`
+- `manage_exchange_config`
+- `get_model_configs`
+- `manage_model_config`
+- `get_strategies`
+- `manage_strategy`
+- `manage_trader`
+- `search_stock`
+- `execute_trade`
+- `get_positions`
+- `get_balance`
+- `get_market_price`
+- `get_trade_history`
+
+下面给出按当前设计目标的建议分类。
+
+### 一、建议继续保留为高层入口的工具
+
+这些工具已经具备较完整的任务语义，短期内可以继续作为高层 skill-like tool 保留。
+
+- `manage_exchange_config`
+- `manage_model_config`
+- `manage_strategy`
+- `manage_trader`
+- `execute_trade`
+
+原因：
+
+- 它们都对应明确的用户任务
+- 内部已经承载了一定业务语义
+- 后续可以直接继续向 skill 演进，而不是推倒重来
+
+重构建议：
+
+- 保持接口稳定
+- 在 planner / prompt 层优先把它们当作 management skill 的执行底座使用
+- 后续逐步把对话语义前移到 `xxx_management`
+
+### 二、建议保留为“只读能力”但弱化对外存在感的工具
+
+这些工具适合继续保留，但主要作为查询型能力存在，不应成为复杂任务的主流程控制中心。
+
+- `get_exchange_configs`
+- `get_model_configs`
+- `get_strategies`
+- `get_positions`
+- `get_balance`
+- `get_market_price`
+- `get_trade_history`
+- `search_stock`
+
+原因：
+
+- 它们更适合做信息补充和状态验证
+- 对诊断问题很有价值
+- 但不应该替代 task-level skill
+
+重构建议：
+
+- 继续保留
+- 主要用于：
+  - skill 内部验证
+  - 诊断类 skill 查询当前状态
+  - 明确的只读用户请求
+- 不要鼓励模型把它们当成“拼工作流”的基础零件反复组合
+
+### 三、建议进一步收敛使用边界的工具
+
+以下工具容易把模型带回到底层操作思维，应该明确边界。
+
+- `get_preferences`
+- `manage_preferences`
+
+原因：
+
+- 长期偏好记忆是辅助能力，不是交易任务主线
+- 如果让模型频繁自由改偏好，容易污染上下文
+
+重构建议：
+
+- 仅在用户明确表达“记住/修改/删除长期偏好”时使用
+- 不要把偏好系统混进交易执行和排障主流程
+
+### 四、建议前移为 management / diagnosis skill 的现有高层工具
+
+下面这些现有高层工具虽然可用，但语义仍然过宽，建议后续逐步前移为 management / diagnosis skill。
+
+#### 1. `manage_trader`
+
+建议逐步前移为：
+
+- `trader_management`
+- `trader_diagnosis`
+
+原因：
+
+- 创建、修改、启动、停止、删除虽然动作不同，但属于同一资源管理域
+- 诊断路径和执行路径应分开
+
+#### 2. `manage_exchange_config`
+
+建议逐步前移为：
+
+- `exchange_management`
+- `exchange_diagnosis`
+
+原因：
+
+- CRUD / query 属于同一资源管理域
+- invalid signature / timestamp / IP 白名单问题需要单独诊断路径
+
+#### 3. `manage_model_config`
+
+建议逐步前移为：
+
+- `model_management`
+- `model_diagnosis`
+
+原因：
+
+- 模型对象管理应集中到一个 management skill
+- provider 配置失败和运行失败应集中到 diagnosis skill
+
+#### 4. `manage_strategy`
+
+建议逐步前移为：
+
+- `strategy_management`
+- `strategy_diagnosis`
+
+原因：
+
+- 策略模板管理和策略问题排查是两类不同任务
+- create / update / activate / duplicate / delete / query 可以统一在 management skill 内处理
+
+### 五、当前最适合直接做成硬 skill 的第一批对象
+
+如果后续开始从“prompt 约束”走向“真正 dispatcher + skill runner”，建议优先落以下几类：
+
+1. `create_trader`
+2. `trader_management`
+3. `exchange_management`
+4. `model_management`
+5. `exchange_diagnosis`
+6. `model_diagnosis`
+7. `trader_diagnosis`
+
+原因：
+
+- 这些最常见
+- 多轮价值最高
+- 失败成本高
+- 用户对稳定性的感知最强
+
+### 六、最终目标
+
+`agent/tools.go` 中的工具未来应逐步承担“skill 的执行底座”角色，而不是直接承担全部对话策略。
+
+也就是说，长期理想状态是：
+
+- 文档层：按 skill 组织
+- 对话层：先匹配 skill
+- 执行层：skill 内部复用现有 tool
+- planner 层：只兜底少数复杂情况

+# NOFXi 诊断与配置 Skills（第一批）
+
+这份文档用于沉淀交易智能助手的第一批高频诊断与配置 skill。
+
+目标不是让模型“更会想”，而是让它面对常见问题时，优先走稳定、可复用的排查路径。
+
+## 设计原则
+
+- 优先按 skill 回答，不要对高频问题重复自由规划
+- 先归类问题，再给出原因、检查项和修复建议
+- 能通过工具验证当前状态时，先查再下结论
+- 敏感信息只指导填写，不完整回显
+- 对结论不确定时，要明确标注为“更可能”或“优先怀疑”
+
+## skill_model_api_setup
+
+### 适用场景
+
+- 用户问某个大模型的 API key 去哪里申请
+- 用户问 base URL 怎么填
+- 用户问 model name 怎么填
+- 用户问 OpenAI / Claude / Gemini / DeepSeek / Qwen / Kimi / Grok / MiniMax 怎么接入
+
+### 处理策略
+
+1. 先确认用户要配置哪个 provider
+2. 告诉用户需要准备的最少字段：
+   - provider
+   - API key
+   - custom_api_url
+   - custom_model_name
+3. 如果系统已有默认地址和默认模型名，优先给推荐值
+4. 回答按步骤组织，不要泛泛解释概念
+
+### 已知实现事实
+
+- 系统内置 provider 默认运行配置，见 `agent.resolveModelRuntimeConfig(...)`
+- 常见 provider 已有默认 URL 和默认 model name
+
+## skill_model_config_diagnosis
+
+### 适用场景
+
+- 模型保存成功但 agent 仍然不可用
+- 提示 AI unavailable
+- 提示模型没启用
+- 提示 custom_api_url 不合法
+- 配置后 trader 不生效
+
+### 优先排查
+
+1. 是否存在已启用模型
+2. API key 是否为空
+3. custom_api_url 是否为合法 HTTPS 地址
+4. custom_model_name 是否为空或不匹配
+5. 当前 trader 是否绑定了这个模型
+6. 更新模型后是否已触发 trader reload
+
+### 已知实现事实
+
+- 非 HTTPS 的 `custom_api_url` 会被后端拒绝，见 `api/handler_ai_model.go`
+- 已启用模型如果缺少 API Key 或 URL，会导致 agent 无法就绪，见 `agent.ensureAIClientForStoreUser(...)`
+- 更新模型配置后，系统会尝试移除并重载相关 trader，使新配置立即生效
+
+### 输出格式
+
+- 现象
+- 更可能原因
+- 先检查什么
+- 下一步怎么修复
+
+## skill_exchange_api_setup
+
+### 适用场景
+
+- 用户要新建交易所 API
+- 用户不知道交易所需要哪些权限
+- 用户问 API key / secret / passphrase 分别填什么
+
+### 通用处理策略
+
+1. 先确认交易所类型
+2. 告知必须权限与禁止权限
+3. 告知是否需要额外字段
+4. 强调 IP 白名单与权限配置
+5. 引导用户回到系统内完成绑定
+
+### 特殊规则
+
+- OKX 除 API Key 和 Secret 外，还需要 passphrase
+- Bybit 永续/合约交易需要合约权限
+- 不建议开启提现权限
+
+### 参考文档
+
+- `docs/getting-started/okx-api.md`
+- `docs/getting-started/bybit-api.md`
+
+## skill_exchange_api_diagnosis
+
+### 适用场景
+
+- `invalid signature`
+- `timestamp` 错误
+- `IP not allowed`
+- `permission denied`
+- 交易所连接不上
+
+### 优先排查
+
+1. 系统时间是否同步
+2. API Key / Secret 是否正确
+3. 是否遗漏额外字段，如 OKX passphrase
+4. IP 白名单是否包含当前服务器
+5. 是否启用了交易或合约权限
+6. 密钥是否过期或已重建
+
+### 已知实现事实
+
+- 时间不同步是 `invalid signature` / `timestamp` 的高频根因，见 `docs/guides/TROUBLESHOOTING.zh-CN.md`
+- OKX 的 passphrase 缺失会导致签名相关问题，见 `docs/getting-started/okx-api.md`
+
+### 输出格式
+
+- 报错现象
+- 最常见根因
+- 优先检查顺序
+- 修复步骤
+
+## skill_trader_start_diagnosis
+
+### 适用场景
+
+- trader 启动不了
+- trader 启动了但没开始交易
+- 页面显示已启动但一直没有动作
+- 用户怀疑 strategy / model / exchange 绑定有问题
+
+### 优先排查
+
+1. 是否有已启用的模型配置
+2. 是否有已启用的交易所配置
+3. trader 是否绑定了 exchange_id / strategy_id / ai_model_id
+4. 交易所余额和权限是否满足下单条件
+5. AI 最近的决策到底是 wait、hold 还是下单失败
+
+### 回答原则
+
+- 要区分“没启动”“启动了但 AI 选择不交易”“尝试下单但失败”这三类
+- 不要把“没开仓”直接等同于“系统故障”
+
+## skill_order_execution_diagnosis
+
+### 适用场景
+
+- 下单失败
+- 只开空不开户 / 只开单边
+- 杠杆报错
+- position side mismatch
+
+### 优先排查
+
+1. 账户模式是否匹配，例如 Binance 是否为 Hedge Mode
+2. 是否为子账户杠杆限制
+3. 合约权限是否开启
+4. 余额、保证金、可交易 symbol 是否满足条件
+
+### 已知实现事实
+
+- Binance 在 One-way Mode 下，可能出现 `position side mismatch` 或单边行为
+- 某些子账户杠杆上限较低，超过限制会直接失败
+- 这些问题在 `docs/guides/TROUBLESHOOTING.md` 已有明确说明
+
+## skill_strategy_diagnosis
+
+### 适用场景
+
+- 用户说策略没生效
+- 用户说 prompt 预览和实际不一致
+- 用户说修改策略后 trader 行为没有变化
+
+### 优先排查
+
+1. 当前编辑的是策略模板，还是 trader 的 custom prompt
+2. 策略是否真的保存成功
+3. 是否需要重新读取当前配置做对比
+4. 用户说的“没生效”是指未保存、未绑定，还是运行结果与预期不一致
+
+### 回答原则
+
+- 先明确“对象”再排查：strategy template / trader / prompt override
+- 如果能读取当前保存值，就不要凭印象判断
+
+## 后续扩展方向
+
+下一批可以继续补：
+
+- `skill_balance_and_position_diagnosis`
+- `skill_market_data_diagnosis`
+- `skill_prompt_generation_diagnosis`
+- `skill_strategy_test_run_diagnosis`
+- `skill_exchange_specific_setup_<exchange>`
+- `skill_model_provider_setup_<provider>`

+# NOFXi Agent 当前设计说明
+
+## 目的
+
+本文描述当前 NOFXi Agent 的实际设计，而不是早期版本的理想设计。重点回答这些问题：
+
+- 用户消息从哪里进入
+- 什么请求会进入 planner
+- 当前有哪些记忆层
+- planner 如何生成与执行 plan
+- tool 现在是怎么设计的
+- 动态快照和当前引用分别解决什么问题
+- 为什么某些问题会出现“看起来有历史，但模型还是会追问”
+
+本文对应的主要实现文件：
+
+- `agent/agent.go`
+- `agent/web.go`
+- `api/agent_routes.go`
+- `agent/planner_runtime.go`
+- `agent/execution_state.go`
+- `agent/memory.go`
+- `agent/history.go`
+- `agent/tools.go`
+
+## 一句话总览
+
+当前 Agent 的运行模型可以概括为：
+
+1. 前端把消息发到 `/api/agent/chat/stream`
+2. 后端把登录用户身份放进 context
+3. Agent 除 `/clear` 和 `/status` 外，其他消息全部进入 planner
+4. planner 结合多层记忆、动态快照和 tool schema 生成 plan
+5. 执行 plan 中的 `tool / reason / ask_user / respond`
+6. 在执行过程中持续更新执行态、短期原话、长期摘要和当前对象引用
+
+## 请求入口
+
+### 前端入口
+
+前端 Agent 页面在：
+
+- `web/src/pages/AgentChatPage.tsx`
+
+当前聊天使用：
+
+- `POST /api/agent/chat/stream`
+
+请求体里会传：
+
+- `message`
+- `lang`
+- `user_key`
+
+### 后端路由入口
+
+路由注册在：
+
+- `api/agent_routes.go`
+
+这里会：
+
+1. 经过 `authMiddleware`
+2. 从登录态里取出 `user_id`
+3. 通过 `agent.WithStoreUserID(...)` 写入 request context
+
+### Agent Web Handler
+
+真正的 HTTP handler 在：
+
+- `agent/web.go`
+
+主要入口：
+
+- `HandleChat(...)`
+- `HandleChatStream(...)`
+
+再往下进入：
+
+- `HandleMessageForStoreUser(...)`
+- `HandleMessageStreamForStoreUser(...)`
+
+## 最外层分流
+
+当前外层分流已经被收口。
+
+在 `agent/agent.go` 中，除了这两个命令之外，其他输入全部交给 planner：
+
+- `/clear`
+- `/status`
+
+也就是说，现在这些都不再在外层直接处理：
+
+- setup flow
+- trade confirmation
+- direct trade regex
+- 自然语言配置流程
+- 自然语言策略创建
+
+这些都统一进入 planner。
+
+这是当前设计里一个很重要的原则：
+
+- 外层分流越少，行为边界越清晰
+- 自然语言理解尽量统一交给 planner + tool
+
+## 当前的 5 层记忆
+
+当前不是 3 层，也不是 4 层，而是 5 层：
+
+1. `chatHistory`
+2. `TaskState`
+3. `ExecutionState`
+4. `CurrentReferences`
+5. `Persistent Preferences`
+
+### 1. chatHistory
+
+定义位置：
+
+- `agent/history.go`
+
+作用：
+
+- 保存最近几轮用户 / assistant 原始消息
+- 给模型保留最近原话上下文
+- 为后续摘要成 `TaskState` 提供原始素材
+
+特点：
+
+- 只保留短期原话
+- 内存态
+- `/clear` 时清空
+
+适合存：
+
+- 最近几轮对话原文
+- 用户的最新措辞
+- 刚刚的自然语言上下文
+
+不适合存：
+
+- 长期真相
+- 当前外部系统状态
+- 当前流程精确执行位置
+
+### 2. TaskState
+
+定义位置：
+
+- `agent/memory.go`
+
+作用：
+
+- 保存跨轮次仍然有意义的高层摘要
+- 注入 planner / reasoning / final response
+
+持久化 key：
+
+- `agent_task_state_<userID>`
+
+字段：
+
+- `CurrentGoal`
+- `ActiveFlow`
+- `OpenLoops`
+- `ImportantFacts`
+- `LastDecision`
+- `UpdatedAt`
+
+适合存：
+
+- 当前高层目标
+- 跨轮次仍然成立的未闭环事项
+- 关键事实
+- 最近一次重要决策及其原因
+
+不适合存：
+
+- step 级待办
+- “下一步调用哪个 tool”
+- 动态余额、持仓、配置存在性
+- 任何可以通过 tool 重新读取的实时状态
+
+### 3. ExecutionState
+
+定义位置：
+
+- `agent/execution_state.go`
+
+作用：
+
+- 保存当前 plan 的执行态
+- 支持 `ask_user` 之后继续执行
+- 保存 plan、当前步骤、执行日志、等待状态等
+
+持久化 key：
+
+- `agent_execution_state_<userID>`
+
+当前关键字段：
+
+- `SessionID`
+- `Goal`
+- `Status`
+- `PlanID`
+- `Steps`
+- `CurrentStepID`
+- `DynamicSnapshots`
+- `ExecutionLog`
+- `SummaryNotes`
+- `Waiting`
+- `CurrentReferences`
+- `FinalAnswer`
+- `LastError`
+
+### 4. CurrentReferences
+
+定义位置：
+
+- `agent/execution_state.go`
+
+作用：
+
+- 记录当前对话里“这个 / 那个 / 刚才那个”到底指的是谁
+
+当前支持的引用对象：
+
+- `strategy`
+- `trader`
+- `model`
+- `exchange`
+
+这是为了解决一种常见问题：
+
+- 用户明明前一轮刚说过“激进策略”
+- 下一轮说“改一下这个策略”
+- 如果没有结构化引用，模型虽然有聊天历史，也容易重新追问
+
+`CurrentReferences` 不是系统状态快照，而是：
+
+- 当前对话焦点对象
+- 当前代词绑定对象
+
+### 5. Persistent Preferences
+
+对应工具：
+
+- `get_preferences`
+- `manage_preferences`
+
+作用：
+
+- 保存用户长期偏好
+
+适合存：
+
+- 默认中文回复
+- 偏好激进风格
+- 更关注 BTC / ETH
+- 不喜欢高频
+- 每天固定时间简报
+
+它和 `TaskState` 的区别是：
+
+- `TaskState` 偏向当前任务摘要
+- `Persistent Preferences` 偏向长期用户画像
+
+## DynamicSnapshots 是什么
+
+`DynamicSnapshots` 是当前真实系统状态的快照。
+
+它不是历史，也不是长期记忆，而是 planner 在规划前或执行中插入的“当前事实”。
+
+当前会进入快照的典型信息包括：
+
+- 当前模型配置列表
+- 当前交易所配置列表
+- 当前策略列表
+- 当前 trader 列表
+- 当前余额
+- 当前持仓
+- 最近交易历史
+
+作用：
+
+- 防止 planner 盲信旧结论
+- 避免“之前没配置，现在其实已经配好了却还说没有”
+- 避免“之前余额是 A，现在拿旧 observation 继续回答”
+
+一句话：
+
+- `DynamicSnapshots` = 当前世界里真实有什么
+
+## CurrentReferences 和 DynamicSnapshots 的区别
+
+这两个容易混淆，但职责完全不同。
+
+`DynamicSnapshots`：
+
+- 当前系统状态快照
+- 是候选集合 / 当前事实
+- 例如当前有两个策略：`激进`、`新策略`
+
+`CurrentReferences`：
+
+- 当前对话焦点对象
+- 是“这个”到底指谁
+- 例如用户现在说的“这个策略”就是 `激进`
+
+可以这样理解：
+
+- `DynamicSnapshots` 是地图
+- `CurrentReferences` 是你手指现在指着地图上的哪个点
+
+## Planner 的输入
+
+planner 主逻辑在：
+
+- `agent/planner_runtime.go`
+
+生成计划时，当前会把这些东西一起送给模型：
+
+- 当前用户请求
+- tool schema
+- `Persistent Preferences`
+- `TaskState`
+- `ExecutionState`
+- `Resume context`
+- `Structured waiting state`
+- `Observation context`
+
+其中 observation context 不是旧版单数组，而是分层后的：
+
+- `dynamic_snapshots`
+- `execution_log`
+- `summary_notes`
+
+## Plan 的结构
+
+当前 planner 只允许这 4 类 step：
+
+- `tool`
+- `reason`
+- `ask_user`
+- `respond`
+
+这意味着现在的 Agent 不是一个“自由发挥的回复器”，而是：
+
+- 先规划
+- 再执行步骤
+- 必要时重规划
+
+## 步骤执行流程
+
+`executePlan(...)` 的核心逻辑是：
+
+1. 找下一个 pending step
+2. 标记 step 为 running
+3. 执行对应类型
+4. 写回 `ExecutionState`
+5. 必要时触发 replanning
+
+不同 step 类型行为如下：
+
+### tool
+
+- 调内部 tool
+- 把结果写入 `ExecutionLog`
+- 根据结果更新 `CurrentReferences`
+- 必要时触发 replanner
+
+### reason
+
+- 发起一次短 reasoning 调用
+- 生成一段简短中间推理
+- 写入 `ExecutionLog`
+
+### ask_user
+
+- 进入 `waiting_user`
+- 保存 `WaitingState`
+- 把问题直接回给用户
+
+### respond
+
+- 生成最终回答
+- 标记当前执行完成
+
+## WaitingState 是什么
+
+`WaitingState` 用来解决：
+
+- 用户回复 `是`
+- 用户回复 `继续`
+- 用户回复 `那个就行`
+
+这类短回复如果没有结构化等待状态，很容易丢上下文。
+
+当前字段包括：
+
+- `Question`
+- `Intent`
+- `PendingFields`
+- `ConfirmationTarget`
+- `CreatedAt`
+
+它的作用是：
+
+- 告诉 planner 上一轮到底在等什么
+- 让这轮短回复更容易被理解成“对上一问的回答”
+
+## CurrentReferences 如何更新
+
+当前是双路径更新：
+
+### 1. 用户消息命中对象名时更新
+
+如果用户说：
+
+- `修改激进策略`
+- `停止 lky`
+- `用 DeepSeek`
+
+系统会去当前用户的策略 / trader / model / exchange 列表里尝试匹配名称或 ID。
+
+匹配成功后，更新 `CurrentReferences`。
+
+### 2. tool 成功返回对象时更新
+
+比如：
+
+- `manage_strategy(create/update/activate)`
+- `manage_trader(create/update)`
+- `manage_model_config(update)`
+- `manage_exchange_config(update)`
+
+只要 tool 返回了具体对象，系统就会把对应 ID / name 写回当前引用。
+
+## Tool 设计
+
+当前 tool 是“资源型 tool”设计，不是“页面动作型 tool”。
+
+### 当前主要工具
+
+配置资源：
+
+- `get_exchange_configs`
+- `manage_exchange_config`
+- `get_model_configs`
+- `manage_model_config`
+
+策略资源：
+
+- `get_strategies`
+- `manage_strategy`
+
+trader 资源：
+
+- `manage_trader`
+
+交易 / 查询资源：
+
+- `search_stock`
+- `execute_trade`
+- `get_positions`
+- `get_balance`
+- `get_market_price`
+- `get_trade_history`
+
+### 为什么这么设计
+
+优点：
+
+- tool schema 稳定
+- 行为边界清晰
+- planner 更容易学会
+- 资源增删改查统一
+
+当前 `manage_strategy` 支持：
+
+- `list`
+- `get_default_config`
+- `create`
+- `update`
+- `delete`
+- `activate`
+- `duplicate`
+
+当前 `manage_trader` 支持：
+
+- `list`
+- `create`
+- `update`
+- `delete`
+- `start`
+- `stop`
+
+## 为什么“创建策略”不该默认依赖交易所和模型
+
+当前设计里，策略模板应该是独立资源：
+
+- `strategy`
+
+而运行态对象是：
+
+- `trader`
+
+更合理的边界是：
+
+- 创建策略模板：用 `manage_strategy`
+- 把策略跑起来：用 `manage_trader`
+
+也就是说：
+
+- 策略不默认依赖交易所和模型
+- 只有当用户要求“运行 / 部署 / 创建 trader”时，才需要进一步关联 exchange / model / trader
+
+## 当前一个完整例子
+
+用户输入：
+
+`帮我创建一个新的激进策略模板，名字就叫激进。创建完后，再把这个策略绑定到 trader lky。`
+
+当前大致流程：
+
+1. 前端请求 `/api/agent/chat/stream`
+2. 后端注入 `store_user_id`
+3. Agent 进入 planner
+4. planner 刷新动态快照：
+   - 当前策略
+   - 当前 trader
+5. 生成 plan，例如：
+   - `get_strategies`
+   - `manage_strategy(create)`
+   - `manage_trader(update)`
+   - `respond`
+6. 执行 `manage_strategy(create)` 后：
+   - 写入 `ExecutionLog`
+   - 更新 `CurrentReferences.strategy`
+7. 执行 `manage_trader(update)` 时：
+   - 直接使用刚创建策略的 ID
+8. 输出最终回复
+
+如果此后用户继续说：
+
+`把这个策略的 prompt 改激进一点`
+
+系统会优先从 `CurrentReferences.strategy` 理解“这个策略”。
+
+## 为什么看起来“有历史”，模型还是会追问
+
+因为“有聊天历史”不等于“有结构化对象绑定”。
+
+如果没有 `CurrentReferences`：
+
+- 模型只能依赖原话文本推断“这个策略”是谁
+- 一旦中间插入多条消息，或者有多个候选策略
+- 就容易重新追问
+
+所以当前设计里，`CurrentReferences` 是补齐这一块的关键。
+
+## 当前已知限制
+
+### 1. 外层虽然已经大幅收口，但仍然不是纯 graph runtime
+
+现在比之前更统一，但整体仍然是：
+
+- Agent 主入口
+- Planner
+- Tool 执行
+
+而不是完整 node-graph 引擎。
+
+### 2. ExecutionState 仍然是按 userID 单槽位
+
+这意味着：
+
+- 同一用户的多个并行任务仍然可能相互影响
+
+更彻底的方向应该是：
+
+- 按 thread / session 多实例存储
+
+### 3. CurrentReferences 目前还是轻量实现
+
+当前只覆盖：
+
+- strategy
+- trader
+- model
+- exchange
+
+后面如果要更强，需要考虑：
+
+- 多候选冲突消解
+- 昵称映射
+- 跨更长会话的稳定实体绑定
+
+## 当前设计的核心思想
+
+一句话总结：
+
+- `chatHistory` 记原话
+- `Persistent Preferences` 记长期偏好
+- `TaskState` 记高层摘要
+- `ExecutionState` 记当前流程
+- `DynamicSnapshots` 记当前事实
+- `CurrentReferences` 记当前指代对象
+- `planner` 决定步骤
+- `tools` 执行落地动作
+
+这就是当前 NOFXi Agent 的实际运行设计。

+# NOFXi Agent Memory And Planning Design
+
+## Purpose
+
+This document explains how the current NOFXi agent handles:
+
+- short-term conversation memory
+- durable task memory
+- durable execution / planning state
+- planner execution and replanning
+- state reset and resume behavior
+
+The implementation described here is primarily in:
+
+- `agent/history.go`
+- `agent/memory.go`
+- `agent/execution_state.go`
+- `agent/planner_runtime.go`
+- `agent/agent.go`
+
+## High-Level Model
+
+The current agent uses three different layers of state:
+
+1. `chatHistory`
+Recent in-memory user/assistant turns for the live conversation.
+
+2. `TaskState`
+Durable summarized context that should survive beyond recent turns.
+
+3. `ExecutionState`
+Durable workflow state for the currently running or recently blocked plan.
+
+These three layers serve different purposes and should not be treated as the same thing.
+
+## State Layers
+
+### 1. `chatHistory`
+
+Defined in `agent/history.go`.
+
+Role:
+
+- stores recent `user` / `assistant` messages in memory
+- keyed by `userID`
+- used as short-term conversational context
+- acts as the source material for later compression into `TaskState`
+
+Characteristics:
+
+- in-memory only
+- capped by `maxTurns`
+- cleared by `/clear`
+- not suitable as durable truth
+
+Typical contents:
+
+- the last few user questions
+- the last few assistant replies
+- temporary conversational wording
+
+### 2. `TaskState`
+
+Defined in `agent/memory.go`.
+
+Role:
+
+- stores durable, structured, non-derivable context
+- persisted through `system_config`
+- injected into planning and reasoning prompts
+
+Storage key:
+
+- `agent_task_state_<userID>`
+
+Fields:
+
+- `CurrentGoal`
+- `ActiveFlow`
+- `OpenLoops`
+- `ImportantFacts`
+- `LastDecision`
+- `UpdatedAt`
+
+Intended contents:
+
+- user goal that still matters across turns
+- high-level unresolved issues that still matter across turns
+- facts that tools cannot cheaply re-fetch
+- latest important decision summary
+
+Explicitly not intended for:
+
+- step-level pending items such as "wait for API key"
+- execution actions such as "call get_exchange_configs"
+- live balances
+- current positions
+- current market prices
+- mutable configuration availability
+
+Those should be checked from tools at planning time instead of being trusted from old summaries.
+
+### 3. `ExecutionState`
+
+Defined in `agent/execution_state.go`.
+
+Role:
+
+- stores the current execution workflow
+- allows the agent to resume after `ask_user`
+- persists plan steps, observations, and completion status
+
+Storage key:
+
+- `agent_execution_state_<userID>`
+
+Fields:
+
+- `SessionID`
+- `UserID`
+- `Goal`
+- `Status`
+- `PlanID`
+- `Steps`
+- `CurrentStepID`
+- `Observations`
+- `FinalAnswer`
+- `LastError`
+- `UpdatedAt`
+
+This is the planner's working state, not a general memory store.
+
+## Data Flow
+
+### Request Entry
+
+Entry points:
+
+- `HandleMessage(...)`
+- `HandleMessageStream(...)`
+
+Flow:
+
+1. user message enters `agent`
+2. slash commands and explicit direct branches are handled first
+3. all other requests go into planner flow via `thinkAndAct(...)` / `thinkAndActStream(...)`
+
+### Planner Flow
+
+The planner pipeline in `agent/planner_runtime.go` is:
+
+1. append user message into `chatHistory`
+2. emit `planning` SSE event
+3. load `ExecutionState`
+4. optionally reset stale `ExecutionState`
+5. optionally refresh dynamic configuration snapshots
+6. create a fresh execution plan with the LLM
+7. execute steps one by one
+8. persist `ExecutionState` after important transitions
+9. append assistant answer into `chatHistory`
+10. maybe compress old conversation into `TaskState`
+
+## Short-Term vs Durable Memory
+
+### What lives in `chatHistory`
+
+Good fits:
+
+- raw recent messages
+- conversational wording
+- latest assistant phrasing
+
+Bad fits:
+
+- long-lived truths
+- current external system state
+
+### What lives in `TaskState`
+
+Good fits:
+
+- durable goal
+- high-level unfinished work that remains relevant across turns
+- important facts the user stated
+- previous decisions and why they were made
+
+Bad fits:
+
+- pending steps inside the current plan
+- execution-level reminders such as "wait for a field" or "call a tool"
+- old conclusions about whether tools exist
+- old conclusions about whether model/exchange config is present
+- live operational state that can change outside the chat
+
+### What lives in `ExecutionState`
+
+Good fits:
+
+- current plan steps
+- observations from tool calls
+- blocked-on-user-input status
+- exact current workflow state
+- step-level pending work and block reasons
+
+Bad fits:
+
+- evergreen user profile
+- long-term semantic memory
+
+## Planning Logic
+
+### Plan Creation
+
+`createExecutionPlan(...)` sends the following into the planner model:
+
+- available tool definitions
+- persistent preferences
+- `TaskState` context
+- `ExecutionState` JSON
+- current user request
+
+The planner must return JSON only with step types:
+
+- `tool`
+- `reason`
+- `ask_user`
+- `respond`
+
+### Step Execution
+
+`executePlan(...)` executes the plan loop:
+
+- `tool`
+  call tool and append observation
+- `reason`
+  run reasoning sub-call and append observation
+- `ask_user`
+  save `waiting_user` state and return question
+- `respond`
+  generate final answer and mark completed
+
+After each completed step, `replanAfterStep(...)` may:
+
+- continue
+- replace remaining steps
+- ask user
+- finish
+
+## Resume Behavior
+
+When `ExecutionState.Status == waiting_user`, the next user turn is treated as a reply to the pending question.
+
+Current safeguards:
+
+- latest asked question is extracted from the stored plan
+- the user reply is appended as a `user_reply` observation
+- planner prompt receives explicit `Resume context`
+
+This prevents short replies like `是` from being misread as unrelated fresh intents as often as before.
+
+## Dynamic State Refresh
+
+Configuration and trader management requests are dynamic by nature. Their truth can change outside the current chat, for example:
+
+- user configures exchange in the UI
+- user adds model in another tab
+- user creates trader elsewhere
+
+Because of that, configuration/trader requests should not trust stale model conclusions.
+
+Current protection in `planner_runtime.go`:
+
+- detects config / trader intent with `isConfigOrTraderIntent(...)`
+- clears `TaskState` context from the planner prompt for these requests
+- refreshes `ExecutionState.Observations` with fresh snapshots from:
+  - `toolGetModelConfigs(...)`
+  - `toolGetExchangeConfigs(...)`
+  - `toolListTraders(...)`
+
+This makes the planner rely more on current system state and less on older narrative memory.
+
+## Reset Strategy
+
+The system currently resets or weakens stale execution state when:
+
+- user says retry-like phrases such as `再试`, `继续`, `try again`, `continue`
+- request is config / trader related and old execution state is failed / completed / waiting
+
+Reset scope:
+
+- `ExecutionState` may be cleared
+- `TaskState` is not globally deleted, but it is intentionally ignored for config/trader planning
+
+Manual reset:
+
+- `/clear`
+
+This clears:
+
+- short-term chat history
+- task state
+- execution state
+
+## Compression Design
+
+`maybeCompressHistory(...)` moves older short-term chat content into `TaskState` when:
+
+- recent message count exceeds the configured window
+- estimated token count exceeds the threshold
+
+Compression strategy:
+
+1. keep recent conversation in `chatHistory`
+2. summarize older turns into structured `TaskState`
+3. persist new `TaskState`
+4. replace `chatHistory` with recent slice
+
+Important design rule:
+
+- `TaskState` should keep durable context only
+- it should not become a stale copy of mutable operational state

+    running --> failed: step error
+    failed --> planning: retry / continue / config-trader reset
+    completed --> planning: new relevant request or retry flow
+```
+
+## Known Design Tradeoffs
+
+### Strengths
+
+- separates short-term chat from durable task summary
+- allows blocked flows to resume
+- supports replanning after every meaningful step
+- can recover from stale assumptions better for dynamic config/trader requests
+
+### Weaknesses
+
+- `TaskState` is still summary-driven, so summarization quality matters
+- planner still depends on model compliance for some transitions
+- `ExecutionState` is single-track per user, not multiple concurrent workflows
+- config/trader intent detection is heuristic and keyword-based
+
+## Practical Guidance
+
+### When to trust `TaskState`
+
+Trust it for:
+
+- user intent continuity
+- open loops
+- durable facts
+
+Do not trust it for:
+
+- whether current exchange/model/trader config exists now
+- whether a specific operational action is currently possible
+
+### When to trust `ExecutionState`
+
+Trust it for:
+
+- current plan continuity
+- exact blocked step
+- latest observation chain
+
+Do not trust it blindly when:
+
+- user has changed configuration outside the chat
+- the system capabilities changed after deployment
+
+### When to fetch live state again
+
+Always prefer fresh tool snapshots before answering about:
+
+- existing model configs
+- existing exchange configs
+- existing traders
+- whether trader creation can proceed
+
+## Suggested Future Improvements
+
+- add workflow versioning so capability changes invalidate stale `ExecutionState`
+- separate `waiting_user_confirmation` from generic `waiting_user`
+- introduce code-level handling for short confirmations such as `是`, `好`, `继续`
+- move dynamic state refresh from heuristic to explicit planner preflight stage
+- support multiple concurrent execution sessions per user if needed

+# NOFXi Agent 记忆与规划设计
+
+## 目的
+
+本文说明当前 NOFXi agent 是如何处理以下能力的：
+
+- 短期对话记忆
+- 持久化任务记忆
+- 持久化执行态 / 规划态
+- planner 的执行与重规划
+- 状态重置与恢复
+
+本文主要对应以下实现文件：
+
+- `agent/history.go`
+- `agent/memory.go`
+- `agent/execution_state.go`
+- `agent/planner_runtime.go`
+- `agent/agent.go`
+
+## 总体模型
+
+当前 agent 使用三层不同的状态：
+
+1. `chatHistory`
+用于保存当前会话最近几轮的原始用户/助手对话，驻留内存。
+
+2. `TaskState`
+用于保存跨轮次仍然有价值的结构化摘要，持久化存储。
+
+3. `ExecutionState`
+用于保存当前规划流程的执行态，支持流程中断后的继续执行。
+
+这三层职责不同，不能混为一谈。
+
+## 三层状态
+
+### 1. `chatHistory`
+
+定义位置：`agent/history.go`
+
+作用：
+
+- 按 `userID` 保存最近的 `user` / `assistant` 消息
+- 作为短期对话上下文
+- 作为后续压缩进 `TaskState` 的原始素材
+
+特性：
+
+- 仅在内存中存在
+- 有 `maxTurns` 上限
+- `/clear` 时会清空
+- 不适合作为长期真相来源
+
+典型内容：
+
+- 最近几轮用户问题
+- 最近几轮助手回答
+- 临时措辞与上下文表达
+
+### 2. `TaskState`
+
+定义位置：`agent/memory.go`
+
+作用：
+
+- 保存持久化、结构化、不可轻易从工具重新推导出的上下文
+- 通过 `system_config` 持久化
+- 注入到 planner / reasoning prompt 中
+
+存储 key：
+
+- `agent_task_state_<userID>`
+
+字段：
+
+- `CurrentGoal`
+- `ActiveFlow`
+- `OpenLoops`
+- `ImportantFacts`
+- `LastDecision`
+- `UpdatedAt`
+
+适合存放：
+
+- 当前仍有效的用户目标
+- 跨轮次仍然成立的高层未闭环问题
+- 无法简单通过工具重新读取的重要事实
+- 最近一次关键决策及原因
+
+不适合存放：
+
+- “等用户提供 API Key” 这类 step 级待办
+- “调用 get_exchange_configs” 这类执行动作
+- 实时余额
+- 当前持仓
+- 当前行情价格
+- 是否存在某个配置这类会变化的状态
+
+这些动态信息应该在规划阶段通过工具重新检查，而不是相信旧摘要。
+
+### 3. `ExecutionState`
+
+定义位置：`agent/execution_state.go`
+
+作用：
+
+- 保存当前执行中的工作流状态
+- 支持 `ask_user` 之后恢复执行
+- 持久化保存计划步骤、观察结果和最终状态
+
+存储 key：
+
+- `agent_execution_state_<userID>`
+
+字段：
+
+- `SessionID`
+- `UserID`
+- `Goal`
+- `Status`
+- `PlanID`
+- `Steps`
+- `CurrentStepID`
+- `Observations`
+- `FinalAnswer`
+- `LastError`
+- `UpdatedAt`
+
+它是 planner 的“工作态”，不是通用记忆仓库。
+
+## 数据流
+
+### 请求入口
+
+入口函数：
+
+- `HandleMessage(...)`
+- `HandleMessageStream(...)`
+
+流程：
+
+1. 用户消息进入 `agent`
+2. 优先处理 slash command 和显式直达分支
+3. 其余请求进入 planner 流程：`thinkAndAct(...)` / `thinkAndActStream(...)`
+
+### Planner 主流程
+
+`agent/planner_runtime.go` 中的 planner 管线如下：
+
+1. 把用户消息加入 `chatHistory`
+2. 发出 `planning` SSE 事件
+3. 加载 `ExecutionState`
+4. 视情况重置过期的 `ExecutionState`
+5. 视情况刷新动态配置快照
+6. 调用 LLM 生成新的执行计划
+7. 按步骤执行计划
+8. 在关键状态变化后持久化 `ExecutionState`
+9. 把助手回答加入 `chatHistory`
+10. 视情况把旧对话压缩进 `TaskState`
+
+## 短期记忆 vs 持久记忆
+
+### `chatHistory` 里应该放什么
+
+适合：
+
+- 最近原始消息
+- 对话措辞
+- 最近一轮助手的表达方式
+
+不适合：
+
+- 长期真相
+- 外部系统当前状态
+
+### `TaskState` 里应该放什么
+
+适合：
+
+- 持续目标
+- 跨轮次仍有意义的高层未闭环事项
+- 用户明确讲过的重要事实
+- 历史关键决策和原因
+
+不适合：
+
+- 当前 plan 中尚未执行的步骤
+- “等待某个字段”“调用某个 tool” 这类执行级待办
+- “系统有没有这个工具” 这种过时结论
+- “当前有没有模型/交易所配置” 这种可变化状态
+- 可以通过工具重新查询到的动态状态
+
+### `ExecutionState` 里应该放什么
+
+适合：
+
+- 当前计划步骤
+- 工具调用观察结果
+- 当前是否卡在等用户补充信息
+- 当前工作流的精确执行位置
+- step 级待办和阻塞原因
+
+不适合：
+
+- 长期用户画像
+- 通用长期语义记忆
+
+## 规划逻辑
+
+### 计划生成
+
+`createExecutionPlan(...)` 会把以下信息送给 planner 模型：
+
+- 当前可用 tool 定义
+- 持久化用户偏好
+- `TaskState` 上下文
+- `ExecutionState` JSON
+- 当前用户请求
+
+planner 必须返回 JSON，且步骤类型只能是：
+
+- `tool`
+- `reason`
+- `ask_user`
+- `respond`
+
+### 步骤执行
+
+`executePlan(...)` 的执行循环如下：
+
+- `tool`
+  调用工具并写入 observation
+- `reason`
+  发起 reasoning 子调用并写入 observation
+- `ask_user`
+  保存 `waiting_user` 状态并把问题返回给用户
+- `respond`
+  生成最终回答并标记完成
+
+每个步骤结束后，`replanAfterStep(...)` 还可以决定：
+
+- continue
+- replace_remaining
+- ask_user
+- finish
+
+## 恢复执行
+
+当 `ExecutionState.Status == waiting_user` 时，下一条用户消息会被视为对上一轮追问的回复。
+
+当前保护机制：
+
+- 从已有 plan 中提取最近一次追问内容
+- 将用户回复作为 `user_reply` observation 追加
+- 在 planner prompt 中注入显式的 `Resume context`
+
+这样可以减少用户只回复 `是` 这类短消息时，被错误理解成全新意图的情况。
+
+## 动态状态刷新
+
+配置类与 trader 管理类请求本质上是动态请求，它们的真相可能在聊天之外发生变化，例如：
+
+- 用户在 Web UI 中配置了交易所
+- 用户在另一个页面新增了模型
+- 用户在别处创建了 trader
+
+因此，这类请求不能依赖旧的模型结论。
+
+当前在 `planner_runtime.go` 中的保护措施：
+
+- 通过 `isConfigOrTraderIntent(...)` 检测配置 / trader 意图
+- 这类请求在 planner prompt 中不再注入旧 `TaskState`
+- 同时刷新 `ExecutionState.Observations` 中的实时快照：
+  - `toolGetModelConfigs(...)`
+  - `toolGetExchangeConfigs(...)`
+  - `toolListTraders(...)`
+
+这样 planner 会更多依赖当前系统状态，而不是依赖旧记忆中的描述。
+
+## 重置策略
+
+当前系统在以下场景会重置或弱化旧执行态：
+
+- 用户说了类似 `再试`、`继续`、`try again`、`continue`
+- 当前请求是配置 / trader 相关，并且旧 `ExecutionState` 已经失败 / 完成 / 正在等待用户
+
+重置范围：
+
+- `ExecutionState` 可能会被清空
+- `TaskState` 不会整体删除，但在配置 / trader 请求中会被主动忽略
+
+手动清理：
+
+- `/clear`
+
+这条命令会清掉：
+
+- 短期 chat history
+- task state
+- execution state
+
+## 压缩设计
+
+`maybeCompressHistory(...)` 会在以下条件满足时把旧的短期对话压缩进 `TaskState`：
+
+- 最近消息数超过窗口
+- 估算 token 数超过阈值
+
+压缩流程：
+
+1. 保留最近若干轮对话在 `chatHistory`
+2. 把更早的内容总结成结构化 `TaskState`
+3. 持久化新的 `TaskState`
+4. 用最近消息切片替换 `chatHistory`
+
+重要设计原则：
+
+- `TaskState` 只保留长期有效上下文
+- 不能把它变成动态运营状态的陈旧副本

+    [*] --> planning
+    planning --> running: plan created
+    running --> waiting_user: ask_user step
+    waiting_user --> planning: user replies
+    running --> completed: respond step finished
+    running --> failed: step error
+    failed --> planning: retry / continue / config-trader reset
+    completed --> planning: new relevant request or retry flow
+```
+
+## 当前设计的取舍
+
+### 优点
+
+- 将短期对话与长期摘要分离
+- 支持在 `ask_user` 之后恢复执行
+- 每个关键步骤后都支持重规划
+- 对配置 / 创建 trader 这类动态请求，已经能更好抵抗旧结论污染
+
+### 缺点
+
+- `TaskState` 的质量仍然依赖总结效果
+- 某些恢复逻辑仍依赖模型是否听话
+- 每个用户当前只有一条 `ExecutionState`，不支持多个并发工作流
+- 配置 / trader 意图识别目前仍是关键词启发式
+
+## 实践建议
+
+### 什么时候该相信 `TaskState`
+
+应该相信它用于：
+
+- 延续用户目标
+- 跟踪未完成事项
+- 保留长期有效事实
+
+不应该相信它用于：
+
+- 当前是否存在模型 / 交易所 / trader 配置
+- 当前是否能够执行某个操作
+
+### 什么时候该相信 `ExecutionState`
+
+应该相信它用于：
+
+- 当前工作流是否仍然连续
+- 当前阻塞在哪一步
+- 最近的 observation 链条
+
+不应该盲信它用于：
+
+- 用户在聊天外已经修改过配置的场景
+- 系统能力或工具集发生变化后的旧结论
+
+### 什么时候必须重新获取实时状态
+
+以下场景应该优先重新通过工具获取：
+
+- 当前模型配置
+- 当前交易所配置
+- 当前 trader 列表
+- 当前是否满足 trader 创建条件
+
+## 后续建议
+
+- 为 `ExecutionState` 增加版本号或能力签名，能力变化时自动失效
+- 将 `waiting_user_confirmation` 与通用 `waiting_user` 分开
+- 对 `是`、`好`、`继续` 这类短确认增加代码级识别
+- 将动态快照刷新从启发式升级为显式 planner 预检查阶段
+- 如果后续需要，支持一个用户多条并发执行会话
