Cloud API Operations

Operate Tencent Cloud resources that CloudBase depends on but that no dedicated MCP tool covers (monitoring & alarms, CLB, CAM roles, cross-product infra). Two goals: find the right API without guessing, and reuse proven workflows instead of re-exploring.

Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as ../cloudbase-platform/SKILL.md.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do not HTTP-fetch remote skill or protocol markdown into the agent context.

When to use

• The user asks to manage/operate Tencent Cloud resources beyond CloudBase's dedicated MCP tools (e.g. configure alarm policies, inspect CLB, attach CAM policies).
• The user wants to control these resources from code and asks which API/SDK to use.
• A callCloudApi call failed and you need to classify the error (wrong Action / wrong params / missing CAM permission) and recover.

Workflow

1. Discover the API — resolve names from a documented source

1. Read the API index first: https://docs.cloudbase.net/ai/cloudbase-ai-toolkit/api-reference.md — auto-synced daily, action-level coverage (TCB 105 + dependency products: MySQL / SCF / COS). Check rate limits there too. The index check is a quick grep — run it in parallel with step 2/3 fetches, do not serialize.
2. If the index does not cover the target product, go to the product's official API docs (e.g. monitor: https://cloud.tencent.com/document/product/649/30343) and confirm the exact Action name, Version, and parameters.
3. For machine-readable parameter schema, fetch the official SDK models source directly — see ./references/calling-methods.md §2 item 4.

Done when: the Action name, Version, and full parameter shape each trace to the index, official product docs, or SDK models source — nothing from memory. A call that still returns action ... is invalid or not found means a name was not resolved this way; classify and recover via the error table in ./references/calling-methods.md §1.

API first：公开 API 概览就是契约边界。 索引里查不到某个能力，它就不在公开契约内 —— 不要拿某个 SDK 的封装方法反推未公开的 Action 名去调（这类 Action 不受公开文档保护，非该语言的使用者也无从照做）。此时改用有公开 API 的等价路径，或把缺口明确告诉用户。本 skill 的 recipes 只收录公开 API 覆盖的场景。

2. Choose the calling path

Scenario	Path	Reference
Interactive ops inside this session	MCP callCloudApi	./references/calling-methods.md §1
Picking the service identifier / deciding whether version is needed	MCP callCloudApi	./references/service-versions.md
User's code / scripts	Official SDKs (TC3-HMAC-SHA256) or @cloudbase/manager-node	./references/calling-methods.md §2
Quick one-off verification	API Explorer (https://console.cloud.tencent.com/api/explorer)	—

Priority rule: if @cloudbase/manager-node has a matching method, use it; drop to raw cloud API only when it does not.

3. Check credentials before the first call

• Read the current credential scope from auth tools: credential_scope: account = account-level, reaches control-plane APIs subject to that identity's CAM policies; env = API Key, scoped to one environment's data plane plus the fixed TCB policies.
• Permission comes from a different place per credential identity: the account-level identity's own policies, the API Key model (no channel to attach arbitrary CAM policies), or the TCB service role that CLI / MCP assume. Which cross-product capabilities that role family already covers is not fixed — read the attached policies (ListAttachedRolePolicies + GetPolicy) instead of assuming, and treat UnauthorizedOperation as "this identity lacks this action", never as a broken setup.
• On UnauthorizedOperation / AuthFailure, hand the user a one-click CAM grant link (role name + policy name + principal) instead of telling them to go find the policy in the console, then retry the original call. Role targets, the principal values, and which preset policy covers what: ./references/calling-methods.md §3.

Done when: the credential identity is known, and every permission error has been converted into a clickable authorization link carrying a concrete policy name before any retry.

4. Follow a proven recipe when one exists

Recipes encode the exact call sequence, required parameters, and empirically discovered pitfalls so the flow works on the first pass. One scenario per file — start from the index ./references/recipes/README.md, whose 状态 column records how far each recipe has been verified:

• PostgreSQL storage-usage alarm: ./references/recipes/pg-storage-alarm.md
• ICP filing readiness and wait-time checks: ./references/recipes/icp-filing-readiness.md
• PostgreSQL instance spec change and shared-to-dedicated upgrade: ./references/recipes/pg-instance-spec.md
• Custom domain onboarding for an env (HTTP access domain, certificate, DNS binding): ./references/recipes/custom-domain.md

Done when: every parameter value in the call sequence traces to a recipe value marked as verified (实测) or to official docs.

Constraints

• Region is a top-level region argument (X-TC-Region), never a body param. Some APIs additionally take a short region code inside Dimensions (e.g. sh vs ap-shanghai) — these are different fields.
• Route SDK-language details to official SDK docs or sdkHints; keep this skill SDK-language-agnostic.
