db

db is a command for Claude Code from textura-agency/next16-claude-starter. It costs 11 tokens per session (236 once invoked), scanned A, original, Unlicense.

A command for setting up or operating Supabase Postgres, a hosted PostgreSQL database service, in a project. It distinguishes the connection used while the app runs from the direct connection used for database migrations.

In plain words
What is it for?
Use it to configure Supabase database access, validate environment variables, set up row-level security policies and indexes, and keep Payload CMS tables separate when Payload manages its own schema.
Why use it?
It prevents using the wrong database connection or exposing server-only credentials. It also requires row-level security, which controls which database rows each user or role may access, for user data.

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 A, and why

db 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.

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.

What it actually says

Supabase task: $ARGUMENTS

Use the supabase-db skill. The things that go wrong first:

  • Connection strings are not interchangeable. Runtime → Supavisor transaction pooler (6543, no prepared statements). Migrations → direct connection (5432). Store both, zod-validated in src/env.ts, server-only.
  • Use the current keys — publishable (sb_publishable_…) client-side, secret (sb_secret_…) server-only. The secret key bypasses RLS entirely.
  • RLS on every user-data table, with a named role and an index on any column a policy filters. Payload's own tables are excluded — Payload enforces its own access control.
  • Never point local dev at production — a schema push will rewrite it.

If Payload owns the schema, Payload owns migrations; use the Supabase CLI only for what sits outside Payload's tables.

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.
