In plain words
What is it for?
Use it when changing Supabase tables, migrations, row-level security policies, authentication, storage buckets, Edge Functions, or generated client types.

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

supabase-workflow 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 9d 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 Workflow

Change Supabase with schema, RLS, client access, and generated types kept in sync.

Process

  1. Identify affected tables, policies, functions, buckets, clients, and user roles.
  2. Decide whether the change belongs in a migration, checked-in config, Edge Function, or application code.
  3. For exposed tables, design RLS policies before depending on frontend access.
  4. Add indexes for policy predicates, joins, filters, and ownership checks.
  5. Keep service role keys on trusted backends only.
  6. Regenerate typed clients when schema changes affect application code.
  7. Test anon/authenticated/service-role paths separately.
  8. Document rollback or follow-up data backfill when migrations are not easily reversible.

Rules

  • Do not use dashboard-only changes as the source of truth.
  • Do not expose service role keys to browser or mobile code.
  • Do not treat anon or publishable keys as secrets; rely on grants and RLS.
  • Write both USING and WITH CHECK when read and write rules differ.

Output

  • Supabase surface affected
  • Migration/config/code changes
  • RLS and key-safety summary
  • Generated type impact
  • Verification checklist

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.
