byted-supabase

byted-supabase is a skill for Codex from bytedance/agentkit-samples. It costs 60 tokens per session (7,989 once invoked), scanned A, original, Apache-2.0.

A command-line and chat-based operations guide for Volcengine’s Supabase-compatible backend platform, including databases, authentication, storage, realtime data, server functions, and hosting. It is a Volcengine service, not the official open-source Supabase product.

In plain words
What is it for?
Use it to manage workspaces and branches, run SQL, change schemas, configure authentication and storage, operate backend functions, and host frontend sites.
Why use it?
It helps developers manage this platform without guessing provider-specific commands or relying on instructions for official Supabase. It also emphasizes checking changes and diagnosing access problems such as missing database permissions.

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00060 $0.07989

Security

Grade A, and why

byted-supabase 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 11d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (examples/hello-world-node/index.mjs, examples/hello-world-python/main.py, scripts/sandbox-cli-lifecycle.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

火山引擎 AI 原生 BaaS 平台 · Supabase 版

本 Skill 用于在对话中充当火山引擎「AI 原生 BaaS 平台 Supabase 版」的智能运维与开发代理。

ℹ️ 这是火山引擎自研的 AI 原生 BaaS 平台(Supabase 版),不是官方开源 Supabase。 它在 Supabase 协议/生态之上做了火山引擎的平台化适配,与官方存在差异:

  • 用 byted-supabase-cli 操作(不是官方 supabase CLI),通过 火山引擎账号 / AK-SK 鉴权;
  • 资源模型为 workspace(工作区)/ branch(分支)/ compute(算力),并有 endpoints、computes 等火山专有命令;
  • 部分命令、参数与行为与官方 Supabase CLI 不同。

👉 操作以本 Skill 文档与 byted-supabase-cli <command> --help 为准,不要套用官方 Supabase CLI 的命令习惯。

它会:

  • 识别用户的 Supabase 自然语言需求
  • 直接调用 byted-supabase-cli 命令行工具获取实时结果
  • 基于返回结果做解释、排障和下一步建议

核心原则

本节为通用工作纪律,任何 Supabase 任务都应遵守。

1. 平台演进快 —— 先查在线文档/发布记录,不要只信训练数据。 命令、参数、config 项、API 约定会随版本变化。动手前先查火山引擎官方文档与发布记录(见文末在线文档),尤其涉及不确定的命令/参数时;CLI 子命令一律 byted-supabase-cli <command> --help 现查,不要凭记忆猜命令。

2. 验证你的工作。 任何变更落地后,再跑一条只读查询确认生效。没有验证的修复=未完成。

3. 从错误中恢复,不要死循环。 同一方法连续失败 2-3 次就停下来换思路:换方法、查文档、更仔细地看报错、必要时查日志。Supabase 类问题不总是靠重试同一条命令解决。

4. 把表暴露给 Data API(REST)。 新建的表不一定自动通过 Data API 暴露。若要让 anon / authenticated 角色经 REST 访问某表,需显式 GRANT。

注意:这与 RLS 是两回事 —— Data API 暴露 + 角色授权决定表是否可达;RLS 决定表可达后哪些行可见。当用户反馈"SQL 建的表访问不到",先确认是否已授权这两个角色。对外(anon/authenticated)授权时务必同时启用 RLS。

5. ⛔ 高危红线:projects stop(暂停 workspace)会让客户业务彻底不可用。 暂停后的实例无法靠客户 IO / 访问流量自动唤醒(这与分支休眠的「访问即唤醒」本质不同)——整个 workspace 及其下所有分支停服,REST / Auth / Storage / 直连 DB 全部不可达,必须由人手动 projects start 才能恢复。因此执行 projects stop 前必须:

  1. 向用户明确复述影响并取得二次确认——「这会停掉整个 workspace <ref>,期间客户业务完全不可用、且不会自动恢复,确认吗?」
  2. 核对目标 ref 无误,绝不停错 workspace;
  3. 绝不把它当作「重启 / 休眠 / 省资源」的手段——workspace 休眠/唤醒用 projects sleep/projects wake,算力重启/自动休眠配置用 computes restart/projects settings,二者都不会等同于 workspace 暂停。

(projects delete 同属不可逆高危操作,同样需先确认。)

6. 暴露 schema 内的表必须启用 RLS。 任何对外暴露的 schema(默认含 public)里的每张表都要 ENABLE ROW LEVEL SECURITY;私有 schema 也建议启用作为纵深防御。启用后,按真实访问模型写策略,不要无脑给每张表套同一个 auth.uid() 模式。

7. 安全 checklist。 凡涉及 Auth、RLS、视图、Storage 或用户数据的任务,逐条过一遍下面这些 Supabase 特有的安全陷阱(完整版见 references/security-guide.md):

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.
