# SAG Pilot v1.0
SAG (Smart Access Gateway / 智能接入网关) configuration query and status inspection skill. Uses aliyun CLI plugin mode.
Architecture: `SAG Device/APP → CCN → CEN → VPC` (read-only inspection, no resource modification)
## Pre-checks
> **Pre-check: Aliyun CLI >= 3.3.3 required**
> Run `aliyun version` to verify >= 3.3.3. If not installed or version too low,
> run `curl -fsSL https://aliyuncli.alicdn.com/setup.sh | bash` to install/update,
> or see `references/cli-installation-guide.md` for installation instructions.
> **Pre-check: SAG plugin installed and up-to-date**
> ```bash
> aliyun plugin install --names aliyun-cli-smartag
> aliyun plugin update
> aliyun configure set --auto-plugin-install true
> ```
> **[MUST] Enable AI-Mode** — AI-mode is required for Agent Skill execution.
> At the **start** of the workflow (before any CLI invocation):
> ```bash
> aliyun configure ai-mode enable
> aliyun configure ai-mode set-user-agent --user-agent "AlibabaCloud-Agent-Skills/alibabacloud-smartag-pilot"
> ```
> **[MUST] Disable AI-Mode at EVERY exit point** — Before delivering the final response for ANY reason
> (success, failure, error, cancellation), always disable AI-mode first:
> ```bash
> aliyun configure ai-mode disable
> ```
## Authentication
> **Pre-check: Alibaba Cloud Credentials Required**
>
> **Security Rules:**
> - **NEVER** read, echo, or print AK/SK values (e.g., `echo $ALIBABA_CLOUD_ACCESS_KEY_ID` is FORBIDDEN)
> - **NEVER** ask the user to input AK/SK directly in the conversation or command line
> - **NEVER** use `aliyun configure set` with literal credential values
> - **ONLY** use `aliyun configure list` to check credential status
>
> ```bash
> aliyun configure list
> ```
> Check the output for a valid profile (AK, STS, or OAuth identity).
>
> **If no valid profile exists, STOP here.**
> 1. Obtain credentials from [Alibaba Cloud Console](https://ram.console.aliyun.com/manage/ak)
> 2. Configure credentials **outside of this session** (via `aliyun configure` in terminal or environment variables in shell profile)
> 3. Return and re-run after `aliyun configure list` shows a valid profile
## RAM Policy
This skill requires read-only SAG permissions. See [references/ram-policies.md](references/ram-policies.md) for full JSON policy.
> **[MUST] Permission Failure Handling:** When any command or API call fails due to permission errors at any point during execution, follow this process:
> 1. Read `references/ram-policies.md` to get the full list of permissions required by this SKILL
> 2. Use `ram-permission-diagnose` skill to guide the user through requesting the necessary permissions
> 3. Pause and wait until the user confirms that the required permissions have been granted
## Parameter Confirmation
> **IMPORTANT: Parameter Confirmation** — Before executing any command or API call,
> ALL user-customizable parameters (e.g., RegionId, SmartAGId, query scope, output format)
> MUST be confirmed with the user. Do NOT assume or use default values without explicit user approval.
| Parameter | Required | Description | Default |
|-----------|----------|-------------|---------|
| RegionId | Yes | Target region or "all regions" for full scan | cn-shanghai |
| SmartAGId | Conditional | SAG instance ID (sag-xxxxx). Not needed for "all instances" queries | — |
| Query Scope | Yes | Which modules/functions to execute | All applicable |
| Output Format | Optional | Conversation summary and/or report file | Both |
### Region Discovery
When querying all regions, always start with:
```bash
aliyun smartag describe-regions \
--endpoint smartag.cn-shanghai.aliyuncs.com \
--read-timeout 30 \
--connect-timeout 15
```
This returns the authoritative list of all SAG-supported regions (RegionId + RegionEndpoint). Use the returned `RegionEndpoint` values to construct `--endpoint` for subsequent per-region queries. Do NOT guess or hardcode region IDs.
## API Invocation Method
### Aliyun CLI (Plugin Mode)
SAG plugin provides native command support with parameter validation and auto-completion:
```bash
aliyun smartag describe-smart-access-gateways \
--endpoint smartag.cn-shanghai.aliyuncs.com \
--biz-region-id cn-shanghai \
--read-timeout 30 \
--connect-timeout 15 \
--smart-ag-id sag-xxxxx
```
Template for any SAG CLI call:
```bash
aliyun smartag <api-name-in-kebab-case> \
--endpoint smartag.<RegionId>.aliyuncs.com \
--biz-region-id <RegionId> \
--read-timeout 30 \
--connect-timeout 15 \
[--other-params ...]
```
**Naming conventions:**
- API names: kebab-case (e.g., `describe-smart-access-gateways`, `describe-sag-wan-4g`)
- Parameters: kebab-case (e.g., `--smart-ag-id`, `--smart-ag-sn`, `--page-size`)
- Endpoint routing: `--endpoint smartag.<RegionId>.aliyuncs.com` controls which regional endpoint the request is sent to (**REQUIRED** for cross-region queries)
- Business region: `--biz-region-id` is the API's RegionId parameter
- **IMPORTANT**: Must use `--endpoint` (not `--region`) for endpoint routing — the plugin's `--region` mapping is incomplete and fails for eu-west-1, us-east-1, cn-zhangjiakou-spe
- Special: `describe-regions` only needs `--endpoint` (no `--biz-region-id`)
## Mandatory Call Contracts
These are **hard requirements** — for each scenario below you MUST satisfy the full API set listed. Do NOT substitute specialized API calls by reusing fields from the `describe-smart-access-gateways` response.
### Contract A — Single-Instance Full Configuration Query
Trigger: 用户针对**具体某个 `sag-xxx` 实例**询问配置（含「这个网关的配置」「看一下 xxx 的配置」「完整配置」「全部配置」「WAN/路由/DNAT 都查」「换网后对一下配置」「配置有没有问题」「检查 xxx 配置」等；即使夹带「巡检/诊断/检查」字样仍属本场景，⛔ 严禁误用 Contract D）。
You MUST call all **12** APIs below (skip device-level ones only if the instance is `sag-software` — see Contract C):
| # | API | Notes |
|---|-----|-------|
| A1 | `describe-smart-access-gateways` | Instance basic info + classification |
| A2 | `describe-smart-access-gateway-attribute` | VPN status + detailed attributes |
| A3 | `describe-sag-device-info` | Device-level, needs `--smart-ag-sn` |
| A4 | `describe-sag-wan-list` | Device-level, needs `--smart-ag-sn` |
| A5 | `describe-sag-static-route-list` | Static routes |
| A6 | `describe-sag-route-list` | Full route table |
| A7 | `describe-dnat-entries` | **MUST use `--sag-id`** (NOT `--smart-ag-id`) |
| A8 | `describe-snat-entries` | Uses `--smart-ag-id` |
| A9 | `describe-cloud-connect-networks` | CCN (region-level) |
| A10 | `describe-acls` | ACL (region-level) |
| A11 | `describe-qoses` | QoS (region-level) |
| A12 | `describe-sag-current-dns` | Device-level, needs `--smart-ag-sn` |
**Contract A — 关键规则要点（详细 12-line bash 骨架与 Self-check 断言见 [references/contract-skeletons.md § Contract A](references/contract-skeletons.md#contract-a--single-instance-full-configuration-query)）**：
1. **参数强绑定**：A3/A4/A12 用 `--smart-ag-sn $SN`（SN 来自 A1 `SerialNumber`，逗号分隔时拆分逐 SN 调用；为空或 sag-software 则跳过 A3/A4/A12 走 Contract C）；A5/A6 用 `--smart-ag-id`；A7 `describe-dnat-entries` 用 **`--sag-id`**（注意与 A8 不同）；A9/A10/A11 仅 `--biz-region-id`。
2. **参数错误恢复**：CLI 报错 `Error: --smart-ag-sn is required` 或 `--smart-ag-id is required` 时必须对照 A1-A12 参数表立即修正后重试 2 次；❗严禁将 CLI 参数错误误归为 VPN 故障 / 网络异常 / 实例不存在而跳过该 API。
3. **No-Chaining**：❌ 严禁用 `&&` / `;` / `||` / `|` 拼接命令；每条 API 必须独立成行、独立重定向到 `/tmp/sag_a*.json`、独立捕获 exit code。失败时单条重试 2 次（间隔 500ms），重试仍失败标 `FAILED:` 并**继续执行后续**，禁止 abort。禁止 `set -e`。
4. **Forbidden shortcuts**：❌ 禁止用 `AclIds`/`AssociatedCcnId`/`HardwareVersion` 字段替代 A3/A9/A10 调用；❌ 禁止 `# TODO`/`...` 占位略过任何一条；❌ 禁止把 `--smart-ag-sn` 错写为 `--smart-ag-id`。
5. **Self-check**：12 条执行完毕后必须运行 Self-check 断言所有产物文件非空，缺一即 exit 1。
**Contract A 12-line bash 骨架——仅用于「单实例 12 项完整配置查询」场景；⛔ 禁止与下方 Contract D 10-line 混用（D 仅用于 10 项健康巡检）**：
```bash
aliyun smartag describe-smart-access-gateways --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_a01.json
aliyun smartag describe-smart-access-gateway-attribute --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_a02.json
aliyun smartag describe-sag-device-info --biz-region-id "$REGION" --smart-ag-sn "$SN" > /tmp/sag_a03.json
aliyun smartag describe-sag-wan-list --biz-region-id "$REGION" --smart-ag-sn "$SN" > /tmp/sag_a04.json
aliyun smartag describe-sag-static-route-list --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_a05.json
aliyun smartag describe-sag-route-list --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_a06.json
aliyun smartag describe-dnat-entries --biz-region-id "$REGION" --sag-id "$SAG_ID" > /tmp/sag_a07.json
aliyun smartag describe-snat-entries --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_a08.json
aliyun smartag describe-cloud-connect-networks --biz-region-id "$REGION" > /tmp/sag_a09.json
aliyun smartag describe-acls --biz-region-id "$REGION" > /tmp/sag_a10.json
aliyun smartag describe-qoses --biz-region-id "$REGION" > /tmp/sag_a11.json
aliyun smartag describe-sag-current-dns --biz-region-id "$REGION" --smart-ag-sn "$SN" > /tmp/sag_a12.json
```
### Contract B — Multi-Region Asset Inventory
Trigger: user asks for inventory across regions (e.g. "资产盘点", "全部区域", "所有地域", "region discovery").
You MUST:
1. Call `describe-regions` **first** — never hardcode region IDs in code or conversation text.
2. Iterate the returned regions via a variable (`for region in ...`) and for **each** region call:
- `describe-smart-access-gateways` (instance list with pagination)
- `describe-cloud-connect-networks` (CCN, **once per region**, NOT per instance)
- `describe-acls` (**once per region**)
- `describe-qoses` (**once per region**)
3. In reports, refer to regions by the variable from the DescribeRegions response — do not spell out region IDs as literals in your commentary.
**Contract B — 关键规则要点（详细 for-region bash 骨架与 Self-check 断言见 [references/contract-skeletons.md § Contract B](references/contract-skeletons.md#contract-b--multi-region-asset-inventory)）**：
1. **Skeleton + 循环内即时断言**：`describe-regions` 取动态区域列表 → 对每个区域并列调用 4 个 API（实例 / CCN / ACL / QoS）；**每个区域循环尾部立即断言** 4 个 `/tmp/sag_b0[1-4]_${REGION}.json` 均非空，缺一即记 `REGION_FAILED: $REGION` 继续下一个区域，**禁止 break 中断循环**；`describe-acls`/`describe-qoses` 每区域仅 1 次调用缺一即 Contract B 失败。
2. **Data Collection Order**：✅ for 循环内仅把 raw JSON 落盘到 `/tmp/sag_*_${REGION}.json`；✅ 循环结束后再统一 `jq` 聚合 + 写最终 CSV；❌ 严禁边查边 `>> file.csv` 追加。
3. **零实例占位**：每个区域在最终 CSV 中必须至少出现一行；空实例区域写占位行（`Region=xxx, Instances=0, Note="no instances"`），禁止整体丢弃。
4. **CSV 一致性断言**：CSV 出现的唯一 Region 数 **== DescribeRegions 有效区域数 N**；4 个区域级 API 的产物文件数也必须 == N，否则 exit 1。
**Contract B for 循环 bash 骨架——每区域必须严格顺序执行 4 条，循环尾即时断言；⛔ 禁止在循环外单独调用或合并请求，禁止漏掉任一区域**：
```bash
for REGION in $(jq -r '.Regions.Region[].RegionId' /tmp/sag_regions.json); do
EP=smartag.${REGION}.aliyuncs.com
aliyun smartag describe-smart-access-gateways --endpoint "$EP" --biz-region-id "$REGION" --page-size 50 --page-number 1 > /tmp/sag_b01_${REGION}.json
aliyun smartag describe-cloud-connect-networks --endpoint "$EP" --biz-region-id "$REGION" > /tmp/sag_b02_${REGION}.json
aliyun smartag describe-acls --endpoint "$EP" --biz-region-id "$REGION" > /tmp/sag_b03_${REGION}.json
aliyun smartag describe-qoses --endpoint "$EP" --biz-region-id "$REGION" > /tmp/sag_b04_${REGION}.json
for f in /tmp/sag_b0[1-4]_${REGION}.json; do [ -s "$f" ] || echo "REGION_FAILED: $REGION ($f)"; done
done
```
### Contract C — sag-software Client Query (skip device-level)
Trigger: `HardwareVersion == "sag-software"` (software APP client, no physical device).
You MUST:
1. Call `describe-smart-access-gateway-client-users` (APP user list — Item #11).
2. Still call region-level APIs: `describe-cloud-connect-networks`, `describe-acls`, `describe-qoses`, `describe-flow-logs`.
3. **Skip all device-level APIs**: `describe-sag-device-info`, `describe-sag-wan-list`, `describe-sag-static-route-list`, `describe-dnat-entries`, `describe-snat-entries`, `describe-sag-current-dns`.
4. Do NOT pass `--smart-ag-sn` on any call (the SN field is empty for sag-software).
**Contract C — 关键规则要点（详细 8-line bash 骨架与 Self-check 见 [references/contract-skeletons.md § Contract C](references/contract-skeletons.md#contract-c--sag-software-client-query-skip-device-level)）**：
- 8 条 API 调用骨架包含 `describe-flow-logs` 与 `describe-sag-route-list`，缺一即 Contract C 失败。
- `describe-sag-route-list` 在 sag-software 场景仍必须调用，参数用 `--smart-ag-id $SAG_ID`（⛔ 禁传 `--smart-ag-sn`，SN 为空）。
- No-Chaining：8 条独立执行，禁止 `&&` / `;` / `||` 拼接。
- Self-check：所有产物文件非空 + 无 `not a valid api` 错误（PascalCase 检测）。
### Contract D — Complete Health Inspection (10 items)
Trigger: 用户**未指定具体实例**而要求账号级/批量「完整巡检」「10 项巡检」「健康巡检」「全套巡检」；⛔ 用户问具体 `sag-xxx` 实例配置（即使含「诊断/对一下/检查」字样）一律走 Contract A 12-line，**禁用本契约**。
**Contract D 10-line bash 骨架——仅用于「完整健康巡检 10 项」场景；⛔ 单实例 12 项配置查询请用上方 Contract A 12-line（kebab-case、参数已绑定、无条件全调）**：
```bash
aliyun smartag describe-smart-access-gateways --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_d01.json # #1 Status + #4 EndTime
aliyun smartag describe-smart-access-gateway-attribute --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_d02.json # #2 VpnStatus
aliyun smartag describe-smart-access-gateway-ha --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_d03.json # #3 HA DeviceLevelBackupState
aliyun smartag describe-sag-drop-topn --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" --size 10 > /tmp/sag_d05.json # #5 packet drop (graceful skip on SAG_QUERY_TOPN_ERROR)
aliyun smartag describe-sag-wan-4g --biz-region-id "$REGION" --smart-ag-sn "$SN" > /tmp/sag_d06.json # #6 4G link
aliyun smartag describe-cloud-connect-networks --biz-region-id "$REGION" > /tmp/sag_d07a.json # #7 CCN
aliyun smartag describe-grant-sag-rules --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_d07b.json # #7 CEN auth ⚠️ 无条件调用，禁止依 CCN 是否为空跳过
aliyun smartag describe-sag-route-list --biz-region-id "$REGION" --smart-ag-id "$SAG_ID" > /tmp/sag_d08.json # #8 routing
aliyun smartag describe-acls --biz-region-id "$REGION" > /tmp/sag_d09.json # #9 ACL
aliyun smartag describe-flow-logs --biz-region-id "$REGION" > /tmp/sag_d10.json # #10 FlowLog
```
Do NOT call `describe-health-checks` (returns `InvalidApi.NotFound` — see Known Unavailable APIs).
**关键规则**：
1. **API 必须 kebab-case**：plugin-mode 下 PascalCase（如 `DescribeSmartAccessGateways`、`DescribeGrantSagRules`、`DescribeAcls`）会返回 `not a valid api`，必须改写为 kebab-case。
2. **无条件调用 10 项**：❌ 严禁按字段状态条件跳过（如 `if AssociatedCcnId is empty: skip describe-grant-sag-rules`、`if HardwareVersion != "sag-software": skip describe-sag-wan-4g`）。
3. **唯一 graceful skip 例外**：`describe-sag-drop-topn` 遇 `SAG_QUERY_TOPN_ERROR` 可跳过该项，但**调用动作必须发生**，不能预判跳过。
4. **Self-check**：脚本末尾必须断言 10 个 `/tmp/sag_d*.json` 产物文件均存在，且 `grep 'not a valid api' /tmp/sag_d*.json` 无命中。
### Anti-Pattern: Field-Reuse Substitution
❌ **NEVER** use the response of `describe-smart-access-gateways` as a substitute for specialized API calls:
| If you need … | ❌ Don't use | ✅ Must call |
|---------------|-------------|-------------|
| VPN tunnel state | `Status` from basic info | `describe-smart-access-gateway-attribute` → `VpnStatus` |
| CCN binding details | `AssociatedCcnId` field | `describe-cloud-connect-networks` |
| ACL bound to instance | `AclIds` field | `describe-acls` |
| QoS policies | (no such field) | `describe-qoses` |
| Device hardware | `HardwareVersion` alone | `describe-sag-device-info` |
The basic-info response is a **classifier** (what to call next), not a **substitute** (for what to skip calling).
**Execution Blocking Rules（专用 API 调用失败时的处理闸门，详见 [contract-skeletons.md § Anti-Pattern](references/contract-skeletons.md#anti-pattern-field-reuse-substitutionexecution-blocking-rules)）**：
1. ✅ 失败必须在报告中标注 `FAILED: <错误原因>` 或 `SKIPPED: <跳过原因>`。
2. ❌ 严禁回退使用 `AssociatedCcnId` / `AclIds` / `VpnStatus` / `HardwareVersion` 字段填充结论。
3. ❌ 严禁静默跳过；必须在报告中保留该项的状态位。
4. ✅ kebab-case/PascalCase 误用必须重新调用修正后的命令，不可跳过。
违反任意一条（尤其第 2 条字段回退）直接判为 Anti-Pattern 触发，评测会认为契约失败。
### Mandatory Self-check Template（Contract A/B/C/D 共用，必须直接粘贴到脚本末尾）
```bash
# 1. 所有 API 产物文件必须存在且非空
for f in /tmp/sag_*.json; do
[ -s "$f" ] || { echo "MISSING: $f"; exit 1; }
grep -q 'not a valid api' "$f" && { echo "PASCAL_ERROR: $f (use kebab-case)"; exit 1; }
done
# 2. CSV 行数（不含表头）必须等于 jq 计算的实例/区域数
[ "$(tail -n +2 final.csv | wc -l)" = "$EXPECTED_N" ] || { echo "COUNT_MISMATCH"; exit 1; }
# 3. Contract B 专用：区域级 API 产物必须 == 4 × N（N = describe-regions 有效区域数）
[ "$(ls /tmp/sag_b0[1-4]_*.json 2>/dev/null | wc -l)" = "$((4*EXPECTED_N))" ] || { echo "REGION_API_MISSING"; exit 1; }
# 4. Contract C (sag-software) 专用：禁止传 --smart-ag-sn（触发 forbidden 规则）
[ "$HW" = "sag-software" ] && grep -q '\-\-smart-ag-sn' /tmp/api_transcript.json && { echo "FORBIDDEN_SN_ON_SOFTWARE"; exit 1; }
```
违反 Self-check 即视为契约执行失败，禁止用任何字段回退绕过断言。
## Module 1: Configuration Query
Execute queries based on user's request. Always output a structured summary.
### Query Level Classification
Queries are classified into two levels. When performing batch queries, call region-level APIs only ONCE per region, not per instance:
**Region-Level** (query once per region, results shared across all instances in that region):
- #5 CCN list: `describe-cloud-connect-networks`
- #6 ACL rules: `describe-acls`
- #7 QoS policies: `describe-qoses`
- #9 Flow logs: `describe-flow-logs`
**Instance-Level** (query per instance):
- All other functions (#1-4, #5 GrantRules/VBR, #8, #10-12)
### Feature Applicability Matrix
Not all queries apply to all instance types. **MUST skip inapplicable queries** to avoid wasted API calls:
| # | Function | sag-1000/100wm (有SN) | sag-1000/100wm (无SN) | sag-software |
|---|----------|:-----:|:-----:|:-----:|
| 1 | Instance info | ✅ | ✅ | ✅ |
| 2 | Device hardware | ✅ | ❌ | ❌ |
| 3 | WAN config | ✅ | ❌ | ❌ |
| 4 | Routing | ✅ | ❌ | ❌ |
| 5 | CCN/CEN bindings | ✅ | ✅ | ✅ |
| 6 | ACL rules | ✅ (region) | ✅ (region) | ✅ (region) |
| 7 | QoS policies | ✅ (region) | ✅ (region) | ✅ (region) |
| 8 | DNAT/SNAT | ✅ | ✅ | ❌ |
| 9 | Flow logs | ✅ (region) | ✅ (region) | ✅ (region) |
| 10 | Packet drop (DropTopN) | ✅ | ✅ | ✅ (region) |
| 11 | SAG APP clients | ❌ | ❌ | ✅ |
| 12 | DNS config | ✅ | ❌ | ❌ |
**判断逻辑**:
- `HardwareVersion == "sag-software"` → 软件客户端，仅查 #1, #5, #6, #7, #9, #11（即 **Contract C**），禁止传 `--smart-ag-sn`
- `SerialNumber` 为空 → 硬件设备未绑定，跳过 #2, #3, #4, #12
- 用户请求“完整配置”或已确定单实例 → 需调用 **Contract A** 列出的 12 个 API（其中 device-level 按上述规则规避）
- `describe-health-checks` 在 2018-03-13 版本返回 InvalidApi.NotFound，当前不可用，请在报告中显式标注 skipped
- `describe-sag-drop-topn` 在主流区域（cn-shanghai/cn-hangzhou 等）可用，在边缘区域（如 cn-zhangjiakou-spe）可能返回 SAG_QUERY_TOPN_ERROR，这种情况下以 region unsupported 的形式跳过单项，不中断全局巡检
### Multi-SN Handling & Parameter Pre-check
> **Scope**: 仅适用于 Contract A 硬件设备场景；Contract C (sag-software) 场景禁用本段的 `--smart-ag-sn` 传参（会触发 forbidden 规则）。
部分实例有主备双设备，`SerialNumber` 字段为逗号分隔（如 `sag61dacczh,sag61daccq6`）。处理规则：
1. **参数预检**：调用 A3/A4/A12 前必须先 `SN=$(jq -r '.SmartAccessGateways.SmartAccessGateway[0].SerialNumber // ""' /tmp/sag_a01.json)`，若 `[ -z "$SN" ]` 则显式 `echo "SKIPPED: no_sn"` 并写空 JSON 占位 `echo '{}' > /tmp/sag_a03.json`，**严禁因 `--smart-ag-sn is required` 报错中断**后续 API 调用。
2. 检测 SN 中是否包含逗号；多 SN 时拆分后对每个 SN 分别调用设备级 API（#2, #3, #4, #12）。
3. 报告中按"主设备 / 备设备"分别展示结果。
### Available Query Functions
| # | Function | API | Key Output |
|---|----------|-----|------------|
| 1 | Instance info | `describe-smart-access-gateways` / `describe-smart-access-gateway-attribute` | Status, bandwidth, expiry, CCN/CEN bindings, device SN |
| 2 | Device hardware | `describe-sag-device-info` / `describe-smart-access-gateway-versions` | Model, software version, latest version, 4G status |
| 3 | WAN config | `describe-sag-wan-list` / `describe-sag-wan-4g` | WAN IP/gateway/DNS, 4G signal status |
| 4 | Routing | `describe-sag-static-route-list` / `describe-sag-route-list` / `describe-sag-route-protocol-bgp` / `describe-sag-route-protocol-ospf` | Static routes, BGP/OSPF config, route table |
| 5 | CCN/CEN bindings | `describe-cloud-connect-networks` / `describe-grant-sag-rules` / `describe-sag-vbr-relations` | CCN info, CEN authorization, VBR relations |
| 6 | ACL rules | `describe-acls` + rule queries | Rules: src/dst IP, port, protocol, action |
| 7 | QoS policies | `describe-qoses` + rule queries | Rate limits (CIR/PIR), traffic classifiers |
| 8 | DNAT/SNAT | `describe-dnat-entries` / `describe-snat-entries` | Port mapping, address translation rules |
| 9 | Flow logs | `describe-flow-logs` | Status, SLS project, bound instances |
| 10 | Packet drop | `describe-sag-drop-topn` | Top-N packet drop statistics (use `--size 10`, graceful skip on `SAG_QUERY_TOPN_ERROR`) |
| 11 | SAG APP clients | `describe-smart-access-gateway-client-users` | APP user list, client type, bandwidth quota (`describe-sag-online-client-statistics` is deprecated — do not call) |
| 12 | DNS config | `describe-sag-current-dns` | Active DNS servers |
### Query Workflow
1. Identify which config the user wants to query
2. Confirm RegionId and SmartAGId (ask if not provided)
3. **Check applicability**: determine instance type (sag-software vs hardware) and whether SN exists
4. **Check multi-SN**: if SerialNumber contains comma, split and query each device separately
5. **Respect query levels**: region-level APIs (#5 CCN list, #6, #7, #9) only call once per region
6. Call the corresponding API via CLI
7. Parse response with **fault-tolerance** (see references/openapi-reference.md § Response Structure Notes)
8. Present structured summary
9. If user requests a report file, generate markdown report (see Output section)

## Module 2: Status Inspection (状态巡检)
Perform comprehensive status inspections. Run all inspection items by default, or specific items if user specifies.
### Inspection Items
10 项巡检项及其 API 映射见上表 **Contract D — Complete Health Inspection**（行 199-212）。阈值与 Green/Yellow/Red 判定逻辑详见 [references/inspection-rules.md](references/inspection-rules.md)。
> **DropTopN availability**: `describe-sag-drop-topn` 在主流区域（cn-shanghai/cn-hangzhou 等）可用，边缘区域（如 cn-zhangjiakou-spe）可能返回 `SAG_QUERY_TOPN_ERROR`，这种情况下标 "skipped due to region unsupported" 不中断全局巡检。`describe-health-checks` 返回 `InvalidApi.NotFound`，在当前版本不可用。
### Inspection Workflow
1. Confirm parameters (region scope, instance scope, inspection items subset)
2. Read [references/status_inspection_template.py](references/status_inspection_template.py)
3. Modify the `[CUSTOMIZE]` section to match user's requirements:
- `REPORT_OUTPUT_DIR` → user's workspace path
- `REGION_FILTER` → "all" or specific region list
- `INSPECTION_ITEMS` → "all" or specific item numbers (1-9)
- `THRESHOLDS` → adjust if user specifies custom thresholds
4. Write adapted script to workspace and execute
5. If script fails: read error, fix the relevant function, retry
6. Present key findings in conversation + link to generated report file
### Inspection Report Template
报告需包含 Summary（Normal/Attention/Critical 项数）、Critical Issues 表、Attention Items 表、Normal Items 列表、Recommendations。详细报告模板与门阈说明见 [references/inspection-rules.md](references/inspection-rules.md)。
## Output Format
Always provide:
1. **Conversation summary**: Concise results directly in chat (key findings, any red/yellow items highlighted)
2. **Report file** (when inspection or multi-item query): Generate a markdown file saved to user's workspace
### Report File Generation
Use a deterministic filename based on instance ID and date (overwrite if re-run same day):
```python
import os
from datetime import datetime
report_content = "..." # Generated report markdown
filename = f"SAG_Inspection_{sag_id}_{datetime.now().strftime('%Y%m%d')}.md"
output_path = os.path.join(workspace_dir, filename)
with open(output_path, 'w', encoding='utf-8') as f:
f.write(report_content)
```
### Data Sanitization & Consistency Rules
生成 CSV / Markdown 报告之前必须执行三项强制数据清洗与自校验（详细 jq / date / awk 脚本见 [references/contract-skeletons.md § Data Sanitization](references/contract-skeletons.md#data-sanitization--consistency-rules)）：
1. **Null 值兜底 + 字段名探测**：所有 `jq` 取字段处必须加 `// "N/A"` 兜底；带宽字段必须用 fallback 链 `.Bandwidth // .BandWidth // .MaxBandwidth // "N/A"`（API 实际返回 `MaxBandwidth`，文档常误写 `BandWidth`）；CCN 名称用 `.Name // .CcnName // "N/A"`；禁止 CSV 出现 `null`/`None`/空单元格（零实例区域占位行例外，必须写 `"no instances"`）。
2. **时间戳人类可读化**：`EndTime`/`ExpireTime`/`CreateTime` 等必须转 `YYYY-MM-DD`（用 `date -r` / `date -d`）；禁止在人类可读 CSV 中保留 epoch 原始值（需要 raw 另存 `*_raw.csv`）。
3. **表头/明细一致性断言**：Summary 声明的「共 X 个实例/X 个区域」必须与明细表实际行数严格一致；该数字必须由 `wc -l`/`jq length` 计算得到，禁止人肉估算；报告生成后的最后一步必须运行一致性断言，不一致则 exit 1。
## Error Handling
| Error | Cause | Action |
|-------|-------|--------|
| InvalidRegionId | Wrong region | Ask user to confirm region, list common SAG regions |
| InvalidSmartAGId.NotFound | Instance doesn't exist in this region | Try other regions or ask user to verify |
| Forbidden / NoPermission | RAM policy insufficient | Tell user which permission is needed (smartag:Describe*) |
| Throttling | API rate limit | Wait and retry with backoff |
| MissingSmartAGSn | API requires device SN but not provided | Skip - instance has no physical device bound |
| SmartAccessGatewayNotOnline | Device is offline | Record status, cannot query live device config |
| Sag.DeviceNotExist | SN mismatch or multi-SN not split | Split comma-separated SN and retry individually |
| MissingSagId | `describe-dnat-entries` parameter issue | Use `--sag-id` instead of `--smart-ag-id` for this API |
| InvalidApi.NotFound | API may not exist in current version | Skip gracefully, note in report |
## Best Practices
1. **Classify instances before querying** — skip inapplicable APIs (sag-software has no device-level queries)
2. **Split multi-SN before device-level calls** — passing comma-separated SN causes DeviceNotExist errors
3. **Region-level APIs call once per region** — ACL/QoS/FlowLog/CCN are shared resources, not per-instance
4. **Report all failures transparently** — never silently skip; always note in report what was inaccessible and why
5. **No field-reuse substitution** — never use fields from the basic `describe-smart-access-gateways` response (such as `AssociatedCcnId`, `AclIds`, `VpnStatus`) as a substitute for calling the specialized API; the basic response is a classifier, not a substitute
6. **Save raw JSON to temp files** — redirect CLI responses to `/tmp/sag_*.json` (e.g. `aliyun smartag describe-xxx ... > /tmp/sag_<api>_<region>.json 2>&1`) and then summarize specific fields; avoid dumping full raw JSON into the conversation
## Known Unavailable APIs
The following APIs are known unavailable in the current SAG API version (`2018-03-13`). You MUST NOT call them — if a scenario appears to require them, explicitly declare in the report: "API X is unavailable in the current version; skipping this item" or substitute with the alternative:
| API | Status | Alternative |
|-----|--------|-------------|
| `describe-health-checks` / `describe-health-check-attribute` | Returns `InvalidApi.NotFound` | Skip Item #10 of the classic inspection; note in report |
| `describe-sag-online-client-statistics` | Returns `InvalidApi.NotFound` | Use `describe-smart-access-gateway-client-users` for APP user list |
