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.

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 | $0.00068 | $0.01060 |
| Opus 5 | $0.00034 | $0.00530 |
| Sonnet 5 | $0.00014 | $0.00212 |
| Haiku 4.5 | $0.00007 | $0.00106 |
Grade A, and why
relational-database-web-cloudbase 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 8d 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.
This is a copy
98% identical to relational-database-web-cloudbase — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 148 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.
CloudBase Relational Database Web SDK
Activation Contract
Use this first when
- A browser or Web app must access CloudBase Relational Database through
@cloudbase/js-sdk. - The task is specifically about frontend initialization and browser-side query usage.
Read before writing code if
- You need to distinguish browser SDK usage from MCP database management or backend Node access.
- The request mentions Supabase migration, shared frontend DB client, or browser-side table queries.
Then also read
- MySQL SQL management and MCP operations ->
../relational-database-mcp-cloudbase/SKILL.md - Web auth/login ->
../auth-web-cloudbase/SKILL.md - General Web app setup ->
../web-development/SKILL.md
Do NOT use for
- MCP-based SQL provisioning, schema changes, or permissions management.
- Backend/Node service access.
- Document database operations.
Common mistakes / gotchas
- Initializing SDKs in an MCP management flow.
- Treating
appitself as the relational database client. - Re-initializing CloudBase in every component.
- Mixing frontend browser access with admin-style schema mutations.
Minimal checklist
- Confirm the caller is a Web frontend.
- Keep one shared CloudBase app and one shared relational DB client.
- Route MySQL provisioning/schema work to
relational-database-mcp-cloudbase. If the task says PostgreSQL, CloudBase PG, PG mode,app.rdb(),queryPgDatabase,managePgDatabase, or RLS, route topostgresql-development-cloudbaseinstead. - Handle auth separately before data access.
Overview
This skill standardizes the browser-side initialization pattern for CloudBase Relational Database.
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.

relational-database-web-cloudbase is a skill published in the GitHub repository sutchan/Agent-Skills-Hub (2 stars, last pushed today), licensed MIT. It adds 68 tokens to every session and 1,060 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to relational-database-web-cloudbase, differing in 2 lines, and is treated as a copy.
