volcengine-cli

Create and manage Volcengine cloud resources using the Volcengine CLI (ve command). Supports all Volcengine services including ECS, VPC, CLB, RDS, Redis, and more. Trigger this skill whenever the user asks to create, query, modify, or delete cloud resources on Volcengine, mentions the ve command, says "volcengine CLI", or describes infrastructure tasks such as "create an ECS instance", "set up a VPC", "list security groups", "allocate an EIP". Also trigger on Chinese prompts mentioning "火山引擎" or "火山" (e.g., "火山引擎上有哪些 ECS"、"查一下我火山的云服务器"、 "火山引擎创建一个 VPC"、"火山的 Redis 实例列一下"). Also trigger when the user encounters errors from ve commands and needs troubleshooting help.

Volcengine CLI Skill

Create and manage Volcengine cloud resources by calling Volcengine OpenAPIs through the ve command.

---

0. Install the ve CLI

If the ve command is not available on the system:

Option 1: npm (recommended)

bash

npm i -g @volcengine/cli

Option 2: GitHub Releases Download: https://github.com/volcengine/volcengine-cli/releases

Verify the installation: ve --version

---

1. Initialization (run at the start of every session)

Profile Selection (fixed for the conversation)

ve can use different credentials through profiles, but the agent must not choose a profile by itself.

• If the user did not explicitly select a profile, use the CLI default resolution: run ve sts GetCallerIdentity directly. Do not list all profiles first and choose one yourself.
• If the user explicitly selected a profile, keep using that same profile for all later commands in this conversation.
• Ordinary service API calls use fixed flags with three hyphens: ---profile <profile-name>, for example ve ecs DescribeInstances ---profile prod.
• CLI management commands use normal flags with two hyphens: ve configure ... --profile, ve login --profile, and ve sso login --profile.
• Skill helper scripts use normal flags with two hyphens, for example python3 scripts/call_extend_api.py --profile prod ....
• Do not infer the desired profile from profile name, region, list order, recent availability, success rate, or task content.
• If the default identity does not match the task risk, or a profile choice is required, tell the user the current default identity, list candidate profile names only, and wait for the user to choose.
• Once a profile is fixed for this conversation, do not switch to another profile unless the user explicitly asks to switch.

Run the identity verification command to confirm that credentials are usable:

bash

ve sts GetCallerIdentity

Success — inform the user of the current account identity and region, then proceed with the task.

Switching regions later: once a profile is set up, ---region on ordinary service API calls and VOLCENGINE_REGION do not override the region baked into it. Switch profiles with ve configure profile --profile <name> only when the user explicitly asks. Use ve configure list only to show candidate profile names; after listing, do not choose a profile yourself. This does not apply to the --region flag on ve login itself, which is required (see below).

Failure — no usable profile. Default plan: use ve login (Console Login, OAuth 2.0 + PKCE). Announce this to the user up front, and tell them they can say "use AK/SK", "use STS token", or "use SSO" to switch.

The same plan applies when a previously working session expires mid-task: any ve command failing with failed to refresh session token. Please run 've login' to re-authenticate (or similar refresh-token/session-expired text) is this exact failure, no matter which skill issued the command. The error text tells the human to run ve login — do not relay that instruction to the user or ask them to run ve login in their own terminal; run the Console Login procedure below yourself and only hand the user the sign-in URL and the code round-trip. Re-login must target the profile that was in use: if a profile was fixed earlier in the conversation, pass it to the startup subcommand selected in step 2 so both the login and its verification hit that profile — omitting it refreshes default, leaves the fixed profile broken, and pollutes the default account context.

First check the ve version:

bash

ve --version

Default: Console Login (requires ve >= 1.0.42)

IMPORTANT: NEVER call ve login directly. ALWAYS use the helper script scripts/ve_login_remote.sh. It handles the OAuth device-flow subprocess lifecycle (FIFO-bound stdin, URL extraction, code feeding, cleanup). Calling ve login directly will orphan the subprocess and make it impossible to feed the authorization code back.

Resolve the login region:

1. If the user named a region in this conversation, use it.
2. Else if VOLCENGINE_REGION is set, use it.
3. Else default to cn-beijing.

Default procedure — commit to this path; do NOT present a menu of login methods:

1. Announce + give the user an off-ramp, then immediately start:

   "I'll start ve login --remote --region <region> now. Say 'use AK/SK' anytime to switch."

2. Start the login subprocess and get the URL:

   Default — use start-wait. Run it as a long-running tool call (for example, a background/async invocation such as run_in_background) that returns an active session while ve login keeps running. It prints the URL and deliberately stays blocked so the wrapper keeps ve login alive. Keep that session active; do not append shell &, and do not wait for it to exit before requesting the code. Run complete through a separate tool call. If unsure which subcommand to use, use start-wait.

   text

   scripts/ve_login_remote.sh start-wait <region> [profile]
   

   Optimization — use start only when the runtime is explicitly known to preserve background descendants after the launching tool call returns (for example, a verified Claude Code environment). It prints the URL and returns immediately via a normal (foreground) tool call while ve login continues in the background.

   text

   scripts/ve_login_remote.sh start <region> [profile]
   

   Fallback — if the runtime cannot keep a long-running tool session active and is not explicitly known to preserve background descendants, do not guess. Skip ve login and fall back to another authentication method (AK/SK, STS token, or SSO) below.

   Both subcommands print a https://signin.volcengine.com/... URL on stdout. Pass [profile] only when the user explicitly fixed a profile earlier in the conversation (never pick one yourself); omit it to use the CLI default resolution. Forward the URL verbatim to the user with: "Open this URL in any browser, complete login, then send me the 'Authorization code' shown on the page."

3. When the user replies with the code, complete the flow:

   text

   scripts/ve_login_remote.sh complete <code> [profile]
   

   The script writes the code into the FIFO bound to the still-running ve, waits for ve to exit, then runs ve sts GetCallerIdentity to verify. Pass the same [profile] you passed to start or start-wait so the verification hits the profile that was just logged in.

   If you used start-wait, its invocation returns after complete finishes the login. Drain that tool session so nothing is left open. If you used start, there is no held tool session to drain.

   Session replacement: When the user is switching to a different account, ve will ask Replace the existing login_session? [y/N]:. The script handles this automatically — complete sends y along with the authorization code, so no manual intervention is needed.

4. If the user interrupts (says "use AK/SK", "cancel", "this is taking too long", etc.):

   text

   scripts/ve_login_remote.sh abort
   

   Then switch to the chosen alternative below.

Critical rules — do NOT improvise OAuth:

• ❌ Do NOT present a menu like "A. URL B. local browser C. AK/SK". Commit to --remote; let the user interrupt to switch.
• ❌ Do NOT let the login subprocess die while waiting for the authorization code. The PKCE challenge dies with it; the URL and any code produced from it become unusable.
• ❌ Do NOT use start unless the runtime is explicitly known to preserve background descendants after the launching tool call returns. Default to start-wait; if unsure, use start-wait.
• ❌ Do NOT detach start-wait with shell &, or wait for it to exit before asking for the code. Keep it in an active long-running tool session and call complete separately.
• ❌ Do NOT pre-fetch the URL by running ve login --remote and exiting. The PKCE challenge dies with the subprocess; the URL becomes useless and the next attempt fails with PKCE mismatch.
• ❌ Do NOT construct signin.volcengine.com/authorize/... URLs yourself.
• ❌ Do NOT decode, parse, or transform the user's reply. Whatever they paste IS the authorization code — pass it verbatim to complete <code>. No base64 decode (even if the string looks base64-shaped), no URL query-string parsing, no extracting code= from callback URLs.
• ❌ Do NOT pipe codes in (echo "<code>" | ve login --remote). The code arrives before the user completes browser login and fails verification.
• ❌ Do NOT spawn parallel ve login subprocesses. One at a time, tracked by the helper.
• ❌ Do NOT call ve login --remote directly. Always go through scripts/ve_login_remote.sh. The script binds ve's stdin to a FIFO so the still-running ve can receive the user's code via a separate complete call. Calling ve directly orphans the subprocess and breaks the code-feeding step.
• ✅ Default to start-wait; use start only in a runtime known to preserve background descendants. Then complete or abort.

Switching region mid-flow: run scripts/ve_login_remote.sh abort, then restart with start-wait (or start if the runtime is known to preserve background descendants). No browser on any device (true offline / CI): skip ve login, fall back to AK/SK below.

If ve login fails (network error, non-interactive terminal, version too old), or the user explicitly asks for a different method, fall back to one of the alternatives below. If installed via npm, upgrade with npm i -g @volcengine/cli@latest.

Alternative: AK/SK (long-term credentials, for CI/CD or scripting)

Ask the user for AccessKey and SecretKey, then:

text

ve configure set --profile default --region cn-beijing \
  --endpoint open.volcengineapi.com \
  --access-key <AK> --secret-key <SK>

For STS (temporary) credentials, also pass --session-token <TOKEN>.

Alternative for the current shell only: export VOLCENGINE_ACCESS_KEY, VOLCENGINE_SECRET_KEY, VOLCENGINE_REGION, optionally VOLCENGINE_SESSION_TOKEN.

Alternative: SSO / Cloud Identity Center (requires ve >= 1.0.38, for enterprise federation)

Three-step setup; ask the user for the SSO start URL and session name first:

text

ve configure sso-session --name <session-name> \
  --start-url https://<sso-host>/userportal \
  --region cn-beijing \
  --registration-scopes cloudidentity:account:access,offline_access

ve configure sso --profile <profile-name> --sso-session <session-name>

ve configure profile --profile <profile-name>

Then ve sso login --sso-session <session-name> (use --no-browser on headless machines).

Credential safety

• Never read ~/.volcengine/config.json — it contains AK/SK and session tokens.
• When running ve configure set with --secret-key, prefer letting the user paste and run the command in their own shell rather than executing it via Claude — secrets passed as command-line arguments end up in shell history and process listings.
• Never echo AK/SK, secret keys, or session tokens back to the user in plain text.

2. Safety Rules (mandatory)

Read/Write Classification

Level	Operation Types	Behavior
Read-only	Describe* / List* / Get* / Query*	Execute directly, no confirmation needed
Write	Create* / Run* / Allocate* / Attach* / Associate* / Authorize*	Show the full command and wait for user confirmation
Destructive	Delete* / Terminate* / Release* / Revoke* / Modify* / Stop* / Detach*	Show command + impact summary; require user confirmation

Core Principles

1. Default to read-only — unless the user explicitly requests a change, execute in read-only mode
2. DryRun first — if a write/destructive operation supports --DryRun true, run a DryRun to preview the plan, then confirm before executing
3. Confirm before executing — show the full command for write operations and wait for approval
4. Protect credentials — never read ~/.volcengine/config.json; never expose access-key, secret-key, or session-token in output

DryRun Notes

A successful DryRun validation returns exit code 1 (non-zero) with DryRunOperation in stderr. This is expected behavior:

text

output=$(ve <svc> <action> --DryRun true ... 2>&1)
if echo "$output" | grep -q "DryRunOperation"; then
  echo "Parameter validation passed"
fi

---

3. Locate APIs and Retrieve Parameters

Locate the API (find the service name + Action name)

text

Step 1: Service name + Action known? -> Use them directly; skip to "Retrieve parameters"
Step 2: Service name known, Action unknown?
  -> ve <service> 2>&1 | grep -i <keyword>
Step 3: Service name also unknown?
  -> ve 2>&1 | grep -i <service keyword>
Step 4: None of the above work?
  -> python3 scripts/find_api.py <keyword>

Retrieve parameters (once the Action is known)

Choose a strategy based on operation type:

Operation Type	Strategy	Rationale
Read-only (Describe/List/Get)	ve <svc> <action> --help	Few, simple parameters — names alone are sufficient
Write/destructive (Create/Run/Delete, etc.)	scripts/fetch_swagger.py for full docs	Many parameters, nested structures — need required fields, examples, and descriptions
Still unclear after --help	Supplement with scripts/fetch_swagger.py	Use whenever parameter meaning is uncertain
Errors like Invalid* / Missing*	Recheck with scripts/fetch_swagger.py	On InvalidParameter, InvalidXxx.NotFound, or MissingParameter, verify parameter names, required fields, and value ranges

text

# Read-only — --help is sufficient
ve ecs DescribeInstances --help

# Write — retrieve full documentation
python3 scripts/fetch_swagger.py --service ecs --action RunInstances

ve command name and API version relationship

• Default version -> ve command = base service name (e.g., iam)
• Non-default version -> ve command = service name + version without hyphens (e.g., iam v2021-08-01 -> iam20210801)
• When in doubt: ve 2>&1 | grep <service> to confirm

Python helper usage

text

# Search for an API (when the service name is unknown)
python3 scripts/find_api.py <keyword> [--limit N]

# Get full API parameter documentation (when descriptions/examples are needed)
python3 scripts/fetch_swagger.py --service <ServiceCode> --action <ActionName>

# List all APIs for a service
python3 scripts/fetch_swagger.py --service <ServiceCode> --list

# Call Extension APIs that public API Explorer/ve does not expose
python3 scripts/call_extend_api.py --list
python3 scripts/call_extend_api.py --describe QueryMetrics

Always pass the base service name to scripts/fetch_swagger.py (e.g., --service iam, not iam20210801) — the script auto-detects the version.

Extension APIs

Some extension APIs are not exposed through ve. For those, consult references/extend-apis.md and use:

bash

python3 scripts/call_extend_api.py --api <APIName> --params '{"Key":"Value"}'

The helper resolves service, version, method, endpoint, content type, and credentials from its registry/environment. For credential resolution details, see references/extend-apis.md. Apply the same read/write/destructive confirmation rules before running extension APIs.

For extension helpers, do not pass --profile unless the user has explicitly selected one for this conversation.

4. Execute API Calls

Basic Format

text

ve <ServiceCode> <ActionName> --ParamName "value"

Parameter Passing Rules

Determine the format from --help output:

• Flat parameter format: --help lists individual --Key type entries (e.g., ECS, VPC, IAM) -> pass with --Key "value"
• Array parameters: prefer the numbered CLI form shown by --help, such as --InstanceIds.1 "$instance_id" or --SubnetIds.1 "$subnet_id". Do not assume JSON-array strings are accepted by every action.
• JSON format: --help only shows --body '{...}' (e.g., Redis, CR, and other POST APIs) -> pass with --body '{...}'

bash

# Flat parameters — nested fields use dot notation; arrays use .N index (starting from 1)
ve ecs RunInstances --ZoneId "cn-beijing-a"
ve ecs RunInstances --NetworkInterfaces.1.SubnetId "subnet-xxxx"
ve ecs RunInstances --Tags.1.Key "publish-by" --Tags.1.Value "deploy-skill"

# JSON format (when --help only shows --body)
ve redis CreateDBInstance --body '{"InstanceName":"demo","RegionId":"cn-beijing","ConfigureNodes":[{"AZ":"cn-beijing-a"}],"ShardedCluster":0,"NodeNumber":2,"ShardCapacity":1024,"ShardNumber":1,"EngineVersion":"6.0","SubnetId":"subnet-xxxx","VpcId":"vpc-xxxx","Password":"<secret>","Tags":[{"Key":"publish-by","Value":"deploy-skill"}]}'

Response Format

json

// Success
{ "ResponseMetadata": { "RequestId": "..." }, "Result": { ... } }

// Failure
{ "ResponseMetadata": { "Error": { "Code": "...", "Message": "..." } } }

Error Handling

Whenever a ve command or extension helper fails, or a response contains ResponseMetadata.Error, read references/common-errors.md completely before diagnosing the error or responding to the user. Partial searches, matched lines, or excerpts do not satisfy this requirement.

First classify the error as request-format, missing dependency, account state, service activation, real-name verification, purchase qualification, or permission related. For product-specific errors, also read the matching service note below. For permission errors (AccessDenied, NoPermission, RoleNotExist, Forbidden, or STS-related failures), activate the volcengine-troubleshooting skill and use its account-permission diagnosis capability to locate the root cause and guide the user through remediation.

Async Resource Creation Requires Polling

Some resources (VKE clusters, RDS instances, ECS instances, etc.) take several minutes to create. After creation, poll the Describe endpoint until the resource reaches the desired status before proceeding.

Creating sub-resources (e.g., security groups) immediately after VPC creation may fail with InvalidVpc.InvalidStatus. Create sub-resources sequentially (subnet first, then security group), or wait a few seconds and retry.

text

# General polling pattern: check every 30 seconds until the target status is reached
while true; do
  cur_status=$(ve <svc> Describe<Resource> --<IdParam> "xxx" 2>&1 | grep -o '"Status":"[^"]*"')
  echo "$(date +%H:%M:%S) $cur_status"
  echo "$cur_status" | grep -q '"Status":"Running"' && break
  sleep 30
done

---

5. End-to-End Execution Flow (Summary)

text

1. Initialize: verify credentials -> GetCallerIdentity -> confirm region
2. Understand the task: is the user querying or making changes?
3. Locate the API: ve --help first -> Python helpers as fallback
4. Query dependent resources: use Describe*/List* to obtain required IDs
5. Read operation -> execute directly and display results
   Write operation -> show command -> DryRun (if supported) -> user confirmation -> execute
6. Parse the response and report results to the user
