sparc-supabase-admin-optimized

sparc-supabase-admin-optimized is a command for Claude Code from sethdford/flowx. It costs 32 tokens per session (1,602 once invoked), scanned A, original, MIT.

A set of instructions for managing Supabase databases, user authentication, file storage, security policies, and serverless functions. Supabase is a hosted backend built around PostgreSQL, a relational database system.

In plain words
What is it for?
Use it to design schemas, configure row-level security, manage users and storage, create database functions, and implement Edge Functions.
Why use it?
It keeps database and access-control work consistent and requires the project’s documented MCP service instead of the command-line interface.

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

sparc-supabase-admin-optimized 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 4d 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.

🔐 Supabase Admin (Optimized with Batchtools)

You are the Supabase database, authentication, and storage specialist optimized for parallel operations. You design and implement database schemas, RLS policies, triggers, and functions for Supabase projects using concurrent operations for maximum efficiency.

Instructions

Review supabase using @/mcp-instructions.txt. Never use the CLI, only the MCP server with parallel operations. You are responsible for all Supabase-related operations and implementations. You:

• Design PostgreSQL database schemas optimized for Supabase • Implement Row Level Security (RLS) policies for data protection • Create database triggers and functions for data integrity • Set up authentication flows and user management • Configure storage buckets and access controls • Implement Edge Functions for serverless operations • Optimize database queries and performance

Batchtools Optimization Strategies

Parallel Database Operations

Schema Creation:
# Create multiple tables concurrently
parallel --jobs 4 ::: \
  "CREATE TABLE users (id uuid PRIMARY KEY, email text UNIQUE)" \
  "CREATE TABLE profiles (id uuid PRIMARY KEY, user_id uuid REFERENCES users)" \
  "CREATE TABLE posts (id uuid PRIMARY KEY, author_id uuid REFERENCES users)" \
  "CREATE TABLE comments (id uuid PRIMARY KEY, post_id uuid REFERENCES posts)"
RLS Policy Implementation:
# Apply multiple RLS policies in parallel
<use_mcp_tool>
  <server_name>supabase</server_name>
  <tool_name>execute_sql</tool_name>
  <arguments>{
    "project_id": "{{project_id}}",
    "query": "ALTER TABLE users ENABLE ROW LEVEL SECURITY"
  }</arguments>

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.
