What is minimal-web-baas-demo?

A guide for quickly building a small CloudBase web application with a database, such as a to-do list, notes app, or message board.

It is for making minimal full-stack web demos using the CloudBase browser SDK, CloudBase database storage, and a preview-first workflow.

It provides a simpler path for basic create, read, update, and delete features without adding server code that the app does not need.

About the project

CloudBase AI Toolkit is an integration layer that lets AI coding tools use Tencent CloudBase as an application backend, including databases, authentication, functions, storage, and deployments. Developers use it to have coding agents build and operate CloudBase-backed applications through skills, plugins, commands, and chat-accessible tools. The catalogue entries are the toolkit’s own skills, agents, hooks, plugins, rules, instructions, and MCP tools.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add TencentCloudBase/CloudBase-AI-Toolkit --skill minimal-web-baas-demo

Clone the repo

git clone --depth 1 https://github.com/TencentCloudBase/CloudBase-AI-Toolkit

Made for: Claude Code.

Or install cloudbase-ai-toolkit, the plugin that ships this one along with the rest of its 47 skills, 3 commands, 2 agents, 2 MCP servers, 2 plugins.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00144	$0.02195
Opus 5	$0.00072	$0.01097
Sonnet 5	$0.00029	$0.00439
Haiku 4.5	$0.00014	$0.00219

Security

Grade A, and why

minimal-web-baas-demo scanned grade A with 0 findings 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 139 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 ../web-development/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.

Minimal Web BaaS Demo (fast path)

Goal: minutes to an interactive Web + database preview, not a cloud-function middleware stack.

This skill is the product equivalent of CloudBase Sites SessionStart Rule 5 (BaaS-first data persistence).

Activation Contract

Use this first when

The user asks for a minimal fullstack / 前后端 demo, message board, Todo, Notes, Kanban, or Lovable/Supabase-like quick app on CloudBase Web.
The user says "带云函数+云数据库" but the real need is CRUD + preview (reinterpret as Web SDK → database).

Do NOT use for

WeChat Mini Programs (wx.cloud) — use ../miniprogram-development/SKILL.md.
True server workloads: payments callbacks, SMS providers, secret third-party keys, cron/ETL, WebSockets — use ../cloud-functions/SKILL.md or ../cloudrun-development/SKILL.md.
Large multi-module products that need ../spec-workflow/SKILL.md.

Hard rules (align with Sites SessionStart Rule 5)

BaaS-first data path
- Schema / admin: Prefer MCP management tools. Do not ask the user to create collections/tables in the console. If MCP tools are missing in this session, configure MCP for next time and use tcb CLI (../cloudbase-cli/SKILL.md) for equivalent schema/admin ops.
  - NoSQL: writeNoSqlDatabaseStructure (create collection / indexes) + permission tools as needed; CLI: NoSQL commands in cloudbase-cli.
  - PostgreSQL: follow ../postgresql-development-cloudbase/SKILL.md (queryPgDatabase / managePgDatabase / migrations); CLI parity via tcb db pg … when MCP is unavailable.
- Reads / writes: @cloudbase/js-sdk in the browser.
  - NoSQL: app.database() → db.collection(...).get()/add()/update()/watch(...).
  - PG: app.rdb().from(...).
- Prefer the template helper (often src/utils/cloudbase.ts). Do not invent a second SDK wrapper.

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.
