- first-seen, last-seen, and latest-scan time ranges;
- allowlisted sort fields such as latest scan time;

+- sorting by last seen, latest scan, risk, vulnerability count, first seen, target name, or port.

 Sorting by latest scan time in ascending order places never-scanned assets first, making coverage gaps visible.

+Frequently used combinations can be saved as filter views. Saved views use the current browser's `localStorage`; they are not synchronized to the server, other browsers, or other users.
+
+The HTTP API and `query_assets` additionally support `max_vulnerabilities`, latest-scan time ranges, and allowlisted creation/update sort fields. HTTP lists allow up to 100 rows per page, while Agent queries allow up to 50.
+
+## Bulk maintenance and export
+
+After selecting assets, you can act on the current page or select every result matching the current filters. Cross-page selection resolves the filters again on the server and is limited to 10,000 assets; narrow the filters when the result exceeds that limit.
+
+Available actions:
+
+- **Bind project**: replace the project binding for all selected assets;
+- **Bulk edit**: change status, responsible person, department, business system, environment, and criticality, and add or remove tags;
+- **Create scan task / Send to chat**: apply one prompt template to the selected assets;
+- **Export CSV / XLSX**: export the currently selected rows in the browser, including ownership, risk, vulnerability count, and timestamp fields;
+- **Merge duplicates**: keep the first selected asset as primary, fill its empty fields from the other records, and union their tags;
+- **Batch delete**: permanently delete the selected assets.
+
+Bulk edit, project binding, and batch delete are all-or-nothing transactions. If any requested asset is missing or outside the caller's scope, the entire operation fails without a partial update.
+
+Merge is only allowed when every duplicate shares a domain, IP address, or Host with the primary asset, and accepts 2-100 selected records.

+| `max_completion_tokens` | Per-response output cap; default is used when empty. |
+| `reasoning` | Default reasoning fields for the channel. Gateway support varies; try `mode: off` first when a provider rejects requests. |
+
+The chat page reads saved channels into the “AI Channel” selector. A non-empty request `aiChannelId` selects a channel for that run/session without sending API credentials through the prompt path. Empty `aiChannelId` follows `ai.default_channel`.
+
+Common Web UI operations:
+

+# Tool Execution Governance
+
+[Back to English documentation](README.md)
+
+This document describes how CyberStrikeAI governs long-running tools, blocking MCP calls, oversized outputs, cancellation, and context restore. The goal is to preserve standard Agent/Eino tool semantics while preventing tool hangs, context blowups, oversized database records, and unsafe resume behavior.
+
+## Goals
+
+- **Keep the agent runner responsive**: tools may run for a long time, but the current runner waits only for a bounded interval.
+- **Allow long tasks to continue**: timeout returns an `execution_id`; later turns can call `wait_tool_execution`.
+- **Support cancellation**: users and agents can cancel a running execution.
+- **Keep DB and agent views identical**: the database stores the same canonical capped result returned to the agent.
+- **Protect resume paths**: resume uses model-facing traces and caps historical oversized tool traces.
+- **Isolate external MCP failures**: external MCP servers are protected by per-server concurrency limits, global concurrency limits, and circuit breakers.
+
+## Execution Model
+
+Tool calls still appear to Eino/Agent as standard tool invocations, but the blocking work runs in a worker:
+
+```text
+Agent calls tool
+  -> ExecutionService creates execution
+  -> worker runs the real MCP/tool call
+  -> Agent bounded wait
+       -> completed: return tool result
+       -> still running: return execution_id, worker continues in background
+```
+
+This prevents MCP servers, `exec`, `sqlmap`, `nmap`, `nuclei`, and similar long-running tools from binding the current runner indefinitely.
+
+## Execution Statuses
+
+| Status | Meaning |
+|---|---|
+| `queued` | Execution exists and is waiting for a worker or concurrency slot |
+| `running` | Worker is executing |
+| `background_running` | UI display state: agent stopped waiting, background worker continues |
+| `completed` | This tool call completed |
+| `failed` | The tool actually failed |
+| `cancelled` | User, agent, or session cleanup cancelled the execution |
+| `hard_timeout` | The tool exceeded its hard timeout |
+| `orphaned` | A persisted running execution no longer has a runtime worker |
+
+Important: when `wait_tool_execution` reaches `timeout_seconds` and the target execution is still running, the wait call itself is a completed observation, not a failed tool execution.
+
+## Control Tools
+
+| Tool | Purpose |
+|---|---|
+| `get_tool_execution` | Read current execution state |
+| `wait_tool_execution` | Wait for a selected execution for a bounded interval |
+| `cancel_tool_execution` | Cancel a selected execution |
+
+`get_tool_execution` and `wait_tool_execution` can include a live output preview:
+
+- `include_partial_output`: whether to return partial output, default `true`.
+- `partial_output_max_bytes`: tail preview limit for this call, default `4096`, maximum `65536`.
+
+Partial output is a bounded preview of output produced so far, not the final `result`. The canonical `result` is still written only when the tool finishes. Tools that do not support streaming output simply omit partial fields.
+
+Typical flow:
+
+```text
+1. Call a long-running tool such as exec/sqlmap/nmap
+2. After tool_wait_timeout_seconds, receive execution_id
+3. Agent can continue reasoning, use other tools, or call wait_tool_execution
+4. If still incomplete, continue waiting or call cancel_tool_execution
+```
+
+`tool_wait_timeout_seconds` applies to internal MCP tools, external MCP tools, and Eino filesystem's streaming `execute`. Eino's non-streaming filesystem tools such as `ls/read_file/write_file/edit_file/glob/grep` are recorded in execution monitoring, but they are not converted into resumable background workers.
+
+## Cancellation and Session Cleanup
+
+- User stop cancels running tools for the current conversation.
+- Normal session end cancels remaining running tools for the current conversation.
+- Interrupt-and-continue style flows do not mass-cancel tools.
+- Conversation-scoped cancellation avoids killing tools from other conversations.
+
+## External MCP Isolation
+
+External MCP servers can hang, disconnect, or return failures. CyberStrikeAI uses three protections:
+
+| Capability | Config | Description |
+|---|---|---|
+| Per-server concurrency | `external_mcp_max_concurrent_per_server` | Max simultaneous calls for one external MCP server |
+| Global concurrency | `external_mcp_max_concurrent_total` | Max simultaneous external MCP calls across all servers |
+| Circuit breaker | `external_mcp_circuit_failure_threshold` / `external_mcp_circuit_cooldown_seconds` | Temporarily fast-fails a server after repeated failures |
+
+Recommended defaults:
+
+```yaml
+agent:
+  external_mcp_max_concurrent_per_server: 2
+  external_mcp_max_concurrent_total: 16
+  external_mcp_circuit_failure_threshold: 3
+  external_mcp_circuit_cooldown_seconds: 60
+```
+
+## Output Governance
+
+CyberStrikeAI uses `multi_agent.eino_middleware.reduction_max_length_for_trunc` as the unified tool result cap. The example configuration uses 50000 bytes.
+
+```yaml
+multi_agent:
+  eino_middleware:
+    reduction_enable: true
+    reduction_max_length_for_trunc: 50000
+```
+
+Coverage:
+
+| Channel | Behavior |
+|---|---|
+| Agent-facing tool result | Uses the canonical capped result |
+| DB / monitor storage | Stores the same canonical result |
+| `get_tool_execution` / `wait_tool_execution` | Reads the same canonical result |
+| Eino `execute` / filesystem monitor records | Capped before completion is persisted |
+| Non-streaming `exec` stdout/stderr | Source-side bounded buffer |
+| Streaming `exec` stdout/stderr | Streamed UI output is also bounded |
+| PTY execution path | Uses the same output cap |
+| Frontend detail modal | Has an additional UI display cap |
+
+When the cap is reached, the full output is written to a local trunc file and the agent-facing payload becomes a `<persisted-output>` notice (with absolute path) that fits inside the configured budget.
+
+Example:
+
+```text
+<persisted-output>
+Output too large (200000). Full output saved to: /path/to/tmp/reduction/conversations/<id>/trunc/<execution_id>
+Use read_file with offset/limit to read parts of the file.
+Preview (first …):
+…
+
+Preview (last …):
+…
+
+</persisted-output>
+```
+
+The current strategy is “spill full text to disk + bounded preview in context.” Agents can recover the original via `read_file`.
+
+## Database and Resume Context
+
+New results are written through this path:
+
+```text
+tool completes
+  -> NormalizeToolResultForStorage
+  -> update in-memory execution
+  -> persist to DB
+  -> return to Agent
+```
+
+So, under normal operation, the DB stores exactly the result returned to the agent.
+
+Resume uses `LastAgentTraceInput`, which is the model-facing trace that actually reached ChatModel, not raw event accumulation. The restore path also caps historical tool content to prevent context blowups from:
+
+- pre-upgrade DB records that contain raw large output,
+- manual imports or migrations,
+- lowering the configured cap from a larger value,
+- future bypasses that accidentally skip canonicalization.
+
+## Recommended Configuration
+
+For long-running security tasks:
+
+```yaml
+agent:
+  max_iterations: 800
+  tool_timeout_minutes: 60
+  tool_wait_timeout_seconds: 30
+  external_mcp_max_concurrent_per_server: 2
+  external_mcp_max_concurrent_total: 16
+  external_mcp_circuit_failure_threshold: 3
+  external_mcp_circuit_cooldown_seconds: 60
+  shell_no_output_timeout_seconds: 1200
+
+multi_agent:
+  eino_middleware:
+    reduction_enable: true
+    reduction_max_length_for_trunc: 50000
+```
+
+| Parameter | Recommended | Notes |
+|---|---:|---|
+| `max_iterations` | `300-1000` | Very large values weaken loop protection |
+| `tool_timeout_minutes` | `60` | Hard timeout for tools such as sqlmap |
+| `tool_wait_timeout_seconds` | `30-60` | Agent wait bound before returning `execution_id` |
+| `shell_no_output_timeout_seconds` | `600-1200` | Kills silent hangs |
+| `reduction_max_length_for_trunc` | `50000` | Unified tool result cap |
+
+Do not make `tool_wait_timeout_seconds` very large by default. Long tasks should continue in workers and be observed by `execution_id`, rather than blocking one turn for several minutes.
+
+## Testing
+
+Long-task test prompt:
+
+```text
+Call exec to run sleep 120. If it is not done after 10 seconds, do not keep waiting; report execution_id, call wait_tool_execution for 5 seconds, then cancel_tool_execution if still incomplete and report final status.
+```
+
+Large-output test prompt:
+
+```text
+Call exec to run: python3 - <<'PY'
+print("A" * 200000)
+PY
+Then show the tool result length and whether it contains the truncation marker.
+```
+
+Expected behavior:
+
+- The initial long task returns an `execution_id` and status `running` or UI `background_running`.
+- `wait_tool_execution` timing out while the target is still running is not displayed as a tool failure.
+- Large output never exceeds `reduction_max_length_for_trunc`.
+- DB, monitor details, and agent continuation use the same capped result.
+
+## Boundaries
+
+- CyberStrikeAI cannot control how a remote external MCP server collects output internally; it caps results after they enter CyberStrikeAI and protects calls with concurrency limits and circuit breakers.
+- Oversized tool output is spilled to local `tmp/reduction/.../trunc/<id>` (or `reduction_root_dir`) before truncation; the bounded result includes an absolute path for `read_file`.

+# 工具执行治理
+
+[返回中文文档](README.md)
+
+本文说明 CyberStrikeAI 对长时间工具、MCP 阻塞、大输出、取消和恢复上下文的治理策略。目标是让 Agent 保持标准工具语义，同时避免工具卡死、上下文爆炸、数据库膨胀或恢复时重新注入历史大输出。
+
+## 设计目标
+
+- **Agent 不被工具绑死**：工具调用可以很慢，但当前 runner 只等待有限时间。
+- **长任务可继续观察**：超时返回 `execution_id`，后续可用 `wait_tool_execution` 多轮等待。
+- **用户和 Agent 都能取消**：当前会话结束或用户停止任务时，会取消仍在运行的工具。
+- **数据库与 Agent 视图一致**：DB 保存的是 Agent 实际拿到的兜底后结果，不再保存另一份原始大输出。
+- **恢复不会撑爆上下文**：续跑使用 model-facing trace；历史异常大 tool trace 恢复时也会再次裁剪。
+- **外部 MCP 有隔离保护**：按 server 限并发、按全局限并发，并对连续失败的 server 熔断。
+
+## 执行模型
+
+普通工具调用仍然对 Eino/Agent 表现为一次标准 tool call，但底层执行分为两段：
+
+```text
+Agent 调用工具
+  -> ExecutionService 创建 execution
+  -> worker 执行真实 MCP/工具调用
+  -> Agent bounded wait
+       -> 完成：返回工具结果
+       -> 未完成：返回 execution_id，worker 继续后台运行
+```
+
+这解决了 MCP server、`exec`、`sqlmap`、`nmap`、`nuclei` 等长任务阻塞当前 runner 的问题。
+
+## 工具状态语义
+
+| 状态 | 含义 |
+|---|---|
+| `queued` | execution 已创建，等待 worker 或并发槽位 |
+| `running` | worker 正在执行 |
+| `background_running` | 前端展示状态，表示本轮 Agent 已停止等待，但后台仍在跑 |
+| `completed` | 本次 tool call 本身已完成 |
+| `failed` | 工具真实失败 |
+| `cancelled` | 用户、Agent 或会话清理主动取消 |
+| `hard_timeout` | 超过硬超时，被系统终止 |
+| `orphaned` | 重启/异常后发现 DB 中仍是 running，但运行时已无对应 worker |
+
+注意：`wait_tool_execution` 到达 `timeout_seconds` 时，如果目标 execution 仍在运行，**这次 wait 调用本身是完成的观察动作**，不是工具执行失败。返回体会说明目标仍为 `running`，前端不应显示为红色失败。
+
+## 控制工具
+
+| 工具 | 用途 |
+|---|---|
+| `get_tool_execution` | 读取 execution 当前状态 |
+| `wait_tool_execution` | 等待指定 execution 一段时间 |
+| `cancel_tool_execution` | 主动取消指定 execution |
+
+`get_tool_execution` 与 `wait_tool_execution` 支持返回运行中输出预览：
+
+- `include_partial_output`：是否返回 partial output，默认 `true`。
+- `partial_output_max_bytes`：本次返回的尾部预览上限，默认 `4096`，最大 `65536`。
+
+partial output 是“已产生输出的有界预览”，不等同于最终 `result`。最终 `result` 仍只在工具结束时写入 canonical execution 记录；不支持流式输出的工具不会返回 partial 字段。
+
+典型流程：
+
+```text
+1. 调用 exec/sqlmap/nmap 等长任务
+2. 超过 tool_wait_timeout_seconds 后拿到 execution_id
+3. Agent 可继续推理、改用其他工具，或调用 wait_tool_execution
+4. 仍未完成时可继续等待，或调用 cancel_tool_execution
+```
+
+`tool_wait_timeout_seconds` 适用于内部 MCP、外部 MCP，以及 Eino filesystem 的流式 `execute`。Eino 的 `ls/read_file/write_file/edit_file/glob/grep` 等非流式 filesystem 工具会写入 execution 监控记录，但不作为后台 worker 做软等待续跑。
+
+## 取消和会话清理
+
+- 用户点击“停止任务”时，会取消当前会话仍在运行的工具。
+- 会话正常结束后，会批量取消当前会话仍 `running` 的工具。
+- “中断并继续”类流程不会做会话级批量取消，以免误杀后续需要等待的 worker。
+- 取消只针对当前 conversation 绑定的 execution，不会误杀其他会话的工具。
+
+## 外部 MCP 隔离
+
+外部 MCP 可能因为远端 server 卡住、断连或返回异常而拖慢 Agent。系统提供三层保护：
+
+| 能力 | 配置 | 说明 |
+|---|---|---|
+| 单 server 并发限制 | `external_mcp_max_concurrent_per_server` | 同一个外部 MCP server 同时运行的工具数 |
+| 全局并发限制 | `external_mcp_max_concurrent_total` | 所有外部 MCP 工具总并发 |
+| 熔断 | `external_mcp_circuit_failure_threshold` / `external_mcp_circuit_cooldown_seconds` | 单 server 连续失败后短期快速失败，避免反复打坏 server |
+
+推荐默认：
+
+```yaml
+agent:
+  external_mcp_max_concurrent_per_server: 2
+  external_mcp_max_concurrent_total: 16
+  external_mcp_circuit_failure_threshold: 3
+  external_mcp_circuit_cooldown_seconds: 60
+```
+
+## 输出兜底
+
+系统使用 `multi_agent.eino_middleware.reduction_max_length_for_trunc` 作为统一工具结果上限。当前示例配置为 50000 bytes。
+
+```yaml
+multi_agent:
+  eino_middleware:
+    reduction_enable: true
+    reduction_max_length_for_trunc: 50000
+```
+
+兜底覆盖：
+
+| 渠道 | 行为 |
+|---|---|
+| Agent 实际拿到的工具结果 | 使用兜底后的 canonical result |
+| DB/监控存储 | 保存同一份 canonical result |
+| `get_tool_execution` / `wait_tool_execution` | 读取同一份 canonical result |
+| Eino `execute` / filesystem 监控记录 | 完成记录前统一兜底 |
+| 非流式 `exec` stdout/stderr | 源头 bounded buffer |
+| 流式 `exec` stdout/stderr | 推送给前端的累计输出也受上限控制 |
+| PTY 执行路径 | 同样受上限控制 |
+| 前端详情弹窗 | 额外有 UI 展示截断保护 |
+
+触发上限后，完整输出先写入本地 trunc 文件，Agent 侧只保留计入预算的 `<persisted-output>` 预览（含绝对路径）。因此阈值为 50000 时，上下文文本不会超过该上限。
+
+示例：
+
+```text
+<persisted-output>
+Output too large (200000). Full output saved to: /path/to/tmp/reduction/conversations/<id>/trunc/<execution_id>
+Use read_file with offset/limit to read parts of the file.
+Preview (first …):
+…
+
+Preview (last …):
+…
+
+</persisted-output>
+```
+
+当前策略是「全文落盘 + 上下文预览」：超过 `reduction_max_length_for_trunc` 时，完整输出写入本地文件（默认 `tmp/reduction/conversations/<会话ID>/trunc/<execution_id>`），Agent/DB/监控拿到的是带绝对路径的 `<persisted-output>` 预览；可用 `read_file` 按 offset/limit 回读全文。
+
+## DB 与恢复上下文
+
+新执行结果的写入路径如下：
+
+```text
+工具完成
+  -> NormalizeToolResultForStorage
+  -> 写入内存 execution
+  -> 写入 DB
+  -> 返回给 Agent
+```
+
+因此正常情况下，DB 中保存的就是 Agent 拿到的结果。
+
+续跑恢复时，系统使用 `LastAgentTraceInput` 中的 model-facing trace，也就是实际送入 ChatModel 的消息快照，而不是原始事件流累计。恢复入口还会对历史 tool 内容再次应用上限，防止以下情况撑爆上下文：
+
+- 升级前 DB 已经存过原始大输出。
+- 手工迁移或导入的数据绕过了当前写入路径。
+- 配置从更大阈值改成 50000。
+- 未来某条旁路写入漏掉 canonicalize。
+
+## 关键配置建议
+
+长任务场景推荐：
+
+```yaml
+agent:
+  max_iterations: 800
+  tool_timeout_minutes: 60
+  tool_wait_timeout_seconds: 30
+  external_mcp_max_concurrent_per_server: 2
+  external_mcp_max_concurrent_total: 16
+  external_mcp_circuit_failure_threshold: 3
+  external_mcp_circuit_cooldown_seconds: 60
+  shell_no_output_timeout_seconds: 1200
+
+multi_agent:
+  eino_middleware:
+    reduction_enable: true
+    reduction_max_length_for_trunc: 50000
+```
+
+参数说明：
+
+| 参数 | 建议 | 说明 |
+|---|---:|---|
+| `max_iterations` | `300-1000` | 太大等于放弃循环保护 |
+| `tool_timeout_minutes` | `60` | 单次工具硬超时，适合 sqlmap 等长任务 |
+| `tool_wait_timeout_seconds` | `30-60` | Agent 本轮等待上限，到时返回 `execution_id` |
+| `shell_no_output_timeout_seconds` | `600-1200` | 连续无输出时终止，防止静默挂死 |
+| `reduction_max_length_for_trunc` | `50000` | 工具结果统一上限 |
+
+不建议把 `tool_wait_timeout_seconds` 设置得很大。长任务应由 worker 后台跑，Agent 通过 `execution_id` 继续观察，而不是一轮等待数分钟。
+
+## 测试建议
+
+可以用以下对话测试长任务语义：
+
+```text
+调用 exec 执行 sleep 120；如果超过 10 秒还没完成，不要一直等，告诉我 execution_id，然后调用 wait_tool_execution 等 5 秒；如果仍未完成，再调用 cancel_tool_execution，最后说明状态。
+```
+
+可以用以下命令测试大输出兜底：
+
+```text
+调用 exec 执行：python3 - <<'PY'
+print("A" * 200000)
+PY
+然后展示工具结果长度和是否包含截断提示。
+```
+
+预期：
+
+- 初始长任务会返回 `execution_id`，状态为 `running` 或前端展示 `background_running`。
+- `wait_tool_execution` 等待到上限但目标未完成时，本次 wait 调用不应显示为执行失败。
+- 大输出结果不会超过 `reduction_max_length_for_trunc`。
+- DB、监控详情、Agent 继续推理看到的是同一份兜底结果。
+
+## 当前边界
+
+- 外部 MCP 的远端 server 内部如何采集输出不由 CyberStrikeAI 控制；CyberStrikeAI 会在结果进入本系统后统一兜底、限并发和熔断。
+- 超长工具输出会在截断前写入本地 `tmp/reduction/.../trunc/<id>`（或 `reduction_root_dir`），bounded result 中包含可 `read_file` 的绝对路径。
