cloud-functions

A development guide for CloudBase functions, which are small pieces of application code run by Tencent CloudBase in response to events or HTTP requests. It covers building, deploying, and debugging these functions.

In plain words
What is it for?
Use it when creating, updating, deploying, or debugging CloudBase Event Functions or HTTP Functions.
Why use it?
It gives runtime-specific guidance for choosing a function type and handling code changes, deployments, logs, and sensitive data safely.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

cloud-functions scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Harvests environment variableshighData exfiltration

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

- **Returning `req.headers`, `process.env`, `event`, or `context` wholesale** — gateways may inject `x-cloudbase-context` (base64 temporary credentials). Never echo that header or dump credential env vars to clients. Fol

How it starts

The opening of the file, as written. The whole thing — 383 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as ../auth-tool-cloudbase/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.

Cross-cutting protocols (required before code changes or deployments):

  • Change Safety Protocol: ../cloudbase-platform/references/protocols/change-safety-protocol.md
  • Deployment Gate: ../cloudbase-platform/references/protocols/deployment-gate.md
  • Sensitive Runtime Data Protection: ../cloudbase-platform/references/protocols/sensitive-runtime-data-protection.md

Cloud Functions Development

Activation Contract

Use this first when

  • The task is to create, update, deploy, inspect, or debug a CloudBase Event Function or HTTP Function that serves application runtime logic.
  • The request mentions function runtime, function logs, scf_bootstrap, function triggers, or function gateway exposure.

Read before writing code if

  • You still need to decide between Event Function and HTTP Function.
  • The task mentions manageFunctions, queryFunctions, manageGateway, or legacy function-tool names.
  • The task might require callCloudApi as a fallback for logs or gateway setup.
  • An HTTP Function will call CloudBase resources through @cloudbase/node-sdk or @cloudbase/manager-node -> read ./references/http-function-credentials.md. HTTP Functions must use explicit credentials; do not rely on the Event Function passwordless runtime path.

Exception only (do not read by default)

  • Migrating an existing app that already uses classic TCP DB clients (DATABASE_URL / Prisma / mysql2 / pg / Redis) → read ./references/vpc-and-tcp-database.md via ./references.md. New business CRUD must prefer CloudBase native SDK (app.database() / app.rdb()) or MCP SQL tools instead of TCP.

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cloud-functions is a skill published in the GitHub repository TencentCloudBase/CloudBase-AI-Toolkit (1,087 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 6,131 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
