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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00015 | $0.02534 |
| Opus 5 | $0.00008 | $0.01267 |
| Sonnet 5 | $0.00003 | $0.00507 |
| Haiku 4.5 | $0.00002 | $0.00253 |
Grade A, and why
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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 429 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Supabase Core Skill
Core concepts, CLI workflow, and patterns common to all Supabase projects.
Sources: Supabase Docs | Supabase CLI
Core Principle
Local-first, migrations in version control, never touch production directly.
Develop locally with the Supabase CLI, capture all changes as migrations, and deploy through CI/CD.
Supabase Stack
| Service | Purpose |
|---|---|
| Database | PostgreSQL with extensions |
| Auth | User authentication, OAuth providers |
| Storage | File storage with RLS |
| Edge Functions | Serverless Deno functions |
| Realtime | WebSocket subscriptions |
| Vector | AI embeddings (pgvector) |
CLI Setup
Install & Login
# macOS
brew install supabase/tap/supabase
# npm (alternative)
npm install -g supabase
# Login
supabase login
Initialize Project
# In your project directory
supabase init
# Creates:
# supabase/
# ├── config.toml # Local config
# ├── seed.sql # Seed data
# └── migrations/ # SQL migrations
Link to Remote
# Get project ref from dashboard URL: https://supabase.com/dashboard/project/<ref>
supabase link --project-ref <project-id>
# Pull existing schema
supabase db pull
Start Local Stack
supabase start
# Output:
# API URL: http://localhost:54321
# GraphQL URL: http://localhost:54321/graphql/v1
# DB URL: postgresql://postgres:postgres@localhost:54322/postgres

# Anon key: eyJ...
# Service role key: eyJ...
Migration Workflow
Option 1: Dashboard + Diff (Quick Prototyping)
# 1. Make changes in local Studio (localhost:54323)
# 2. Generate migration from diff
supabase db diff -f <migration_name>
# 3. Review generated SQL
cat supabase/migrations/*_<migration_name>.sql
# 4. Reset to test
supabase db reset
Option 2: Write Migrations Directly (Recommended)
# 1. Create empty migration
supabase migration new create_users_table
# 2. Edit the migration file
# supabase/migrations/<timestamp>_create_users_table.sql
# 3. Apply locally
supabase db reset
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.

supabase is a skill published in the GitHub repository alinaqi/maggy (705 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 2,534 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
