name: byted-util-volcengine-cloud-detect description: Volcengine Cloud Detect (云拨测) API integration for creating detection tasks, retrieving results, generating reports, and managing detection nodes. Use when the user wants to (1) create network detection/dialing tasks (拨测任务), (2) check task results or generate detection reports, (3) list or search detection nodes (拨测节点), (4) manage existing tasks (list/stop/restart/delete). Triggers include natural language requests about website monitoring, network latency testing, HTTP detection, ping tests, DNS tests, node queries, or report generation for Volcengine cloud detect service.

Volcengine Cloud Detect

Interact with Volcengine Cloud Detect API (云拨测) through natural language. All API calls are handled via scripts/volc_detect.py. For detailed API parameters, read references/api_docs.md.

Prerequisites

Volcengine credentials are required:

• VOLC_ACCESSKEY: Access Key
• VOLC_SECRETKEY: Secret Key

Before executing any command, check whether both credentials exist in environment variables:

test -n "$VOLC_ACCESSKEY" && test -n "$VOLC_SECRETKEY"

If either value is missing, ask the user to provide the missing AK/SK, then write them to the current shell environment and persist them to the user's shell profile:

export VOLC_ACCESSKEY="USER_PROVIDED_ACCESS_KEY"
export VOLC_SECRETKEY="USER_PROVIDED_SECRET_KEY"

SHELL_PROFILE="${ZDOTDIR:-$HOME}/.zshrc"
grep -q '^export VOLC_ACCESSKEY=' "$SHELL_PROFILE" 2>/dev/null \
  && sed -i '' 's|^export VOLC_ACCESSKEY=.*|export VOLC_ACCESSKEY="USER_PROVIDED_ACCESS_KEY"|' "$SHELL_PROFILE" \
  || printf '\nexport VOLC_ACCESSKEY="USER_PROVIDED_ACCESS_KEY"\n' >> "$SHELL_PROFILE"
grep -q '^export VOLC_SECRETKEY=' "$SHELL_PROFILE" 2>/dev/null \
  && sed -i '' 's|^export VOLC_SECRETKEY=.*|export VOLC_SECRETKEY="USER_PROVIDED_SECRET_KEY"|' "$SHELL_PROFILE" \
  || printf 'export VOLC_SECRETKEY="USER_PROVIDED_SECRET_KEY"\n' >> "$SHELL_PROFILE"

Never run scripts/volc_detect.py until both VOLC_ACCESSKEY and VOLC_SECRETKEY are available.

Default Parameters for CreateTask

When user creates a task without specifying all parameters, use these defaults:

Parameter	Default Value	Notes
ProjectName	default	Always use unless user specifies
Type	1 (HTTP(S))	Task type
Name	{current_time}_claw_detect	Format: YYYYMMDD_HHMMSS_claw_detect
Address	(required)	Must ask user if not provided
NodeCount	5	Samples per line
IntervalSeconds	60	Detection frequency
FinishTime	current_time + 90 seconds	1.5 minutes after creation
LineIdList	(required)	Must obtain from ListNodes

Task Type Mapping: 1=HTTP(S), 2=DNS, 3=PING, 5=UDP, 6=TCP, 8=Upload, 9=Download, 11=PageElement

Interval Options (seconds): 60, 120, 180, 300, 600, 900, 1200, 1800, 3600, 7200, 10800, 21600, 43200, 86400

Workflow: Creating a Detection Task

1. Collect required info: Ask user for Address (target URL). If not provided, prompt for it.
2. Determine node selection: Before creating task, ask user about detection requirements to filter nodes:
   • Target region? (e.g., mainland China, specific provinces/cities)
   • ISP preference? (e.g., China Telecom, China Mobile, China Unicom)
   • Node type? (IDC = data center, LastMile = end user)
3. Fetch and filter nodes: Run list-nodes, then fuzzy-search based on user requirements.
4. Confirm LineIdList: Show matched nodes to user and confirm selection.
5. Create task: Run create-task with all parameters including confirmed LineIdList.
6. Return TaskId: Present the created task ID to user.

Node Selection Conversation Guide

When user says "create a detection task for baidu.com", respond by:

1. Confirming the target address
2. Asking about geographic/ISP requirements
3. Running list-nodes to show available options
4. Using fuzzy-search-nodes to filter based on user's description

Example user requirements to node filters:

• "mainland China + Telecom" → --is-mainland true + search "电信"
• "Beijing IDC nodes" → search "北京 IDC"
• "Shanghai and Guangzhou Mobile" → search "上海 移动" and "广州 移动"
• "all over the country" → --is-mainland true, select diverse nodes

Workflow: Getting Results & Reports

1. Get task results: Run get-result with TaskId and time range (must be <= 1 hour).
2. Generate report: Run generate-report to produce summary statistics.
3. Present findings: Show key metrics in a concise format.

Report Format

Present reports using this structure:

## Detection Report for {TaskName} (ID: {TaskId})

**Time Range**: {start} ~ {end}
**Total Samples**: {N}
**Success Rate**: {X}%

### Latency Statistics (ms)
| Metric | Value |
|--------|-------|
| Avg | {avg} |
| Min | {min} |
| Max | {max} |
| P90 | {p90} |

### Status Code Distribution
| Code | Count |
|------|-------|
| ... | ... |

### Issues
- {N} failures from {region-isp} nodes
- Top error: {error_code} ({count} occurrences)

Workflow: Managing Tasks

• List tasks: list-tasks with optional filters (--name, --address)
• Stop task: stop-task --task-id ID
• Restart task: restart-task --task-id ID
• Delete task: delete-task --task-id ID (confirm with user first)
• Get task details: get-task --task-id ID

Workflow: Node Discovery

• List all nodes: list-nodes [--is-mainland true|false]
• Filter by type: list-nodes --line-types 1,2 (1=LastMile, 2=IDC)
• Fuzzy search: fuzzy-search-nodes "search query"

Key API Notes

• Time constraints: GetTaskResult time range must be <= 1 hour
• Page size limit: GetTaskResult max PageSize is 500
• Node naming format: 国家-省份-城市-运营商（类型）, e.g., 中国-北京-北京市-中国电信（IDC）
• Task status: 2=Running, 4=Paused, 6=Ended
• Project scoping: All task-scoped commands (create-task, get-result, get-task, list-tasks, stop-task, restart-task, delete-task, generate-report, list-nodes) accept an optional --project-name. create-task defaults to default; the others default to the account's default project when omitted.
