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.

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 | $0.00080 | $0.01613 |
| Opus 5.5 | $0.00032 | $0.00645 |
| Sonnet 5.5 | $0.00016 | $0.00323 |
| Haiku 4.5 | $0.00008 | $0.00161 |
Grade B, and why
Supabase Local Development scanned grade B with 1 finding 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 1mo 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Supabase Local Development
Overview
Supabase Local Development provides a complete local Postgres database with all Supabase services (Auth, Storage, Edge Functions, Realtime) running in Docker containers. This enables offline development, faster iteration, and safe database migrations before deploying to production.
Key benefits:
- Full Supabase stack running locally
- Faster development without network latency
- Safe migration testing before production
- Automatic TypeScript type generation
- Environment variable management

Prerequisites
Docker Runtime
Supabase local development requires a Docker-compatible container runtime:
- Docker Desktop (macOS, Windows, Linux)
- Rancher Desktop (macOS, Windows, Linux)
- OrbStack (macOS) - Recommended for Apple Silicon
- Podman (macOS, Windows, Linux)
Verify Docker is running:
docker info
Supabase CLI
Install via npm (recommended for Next.js projects):
npm install -g supabase
Or via Homebrew (macOS):
brew install supabase/tap/supabase
Verify installation:
supabase --version
Workflow
Step 1: Initialize Supabase Project
supabase init
This creates a supabase/ directory with:
config.toml- Local configurationseed.sql- Optional seed datamigrations/- Database migrations
Step 2: Start Local Services
supabase start
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 Local Development is a skill published in the GitHub repository constellos/claude-code (5 stars, last pushed 1mo ago), licensed MIT. It adds 80 tokens to every session and 1,613 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
