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: 7 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 | $0.00033 | $0.01927 |
| Opus 5 | $0.00016 | $0.00963 |
| Sonnet 5 | $0.00007 | $0.00385 |
| Haiku 4.5 | $0.00003 | $0.00193 |
Grade A, and why
supabase-cli 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 7d 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 CLI
CLI automation and operational tooling for Supabase development workflows. This skill provides scripts and utilities for common Supabase operations with built-in safety checks.
When to Use
Invoke when:
- Creating or applying database migrations
- Deploying Edge Functions
- Managing Supabase secrets
- Generating TypeScript types from schema
- Executing SQL with safety checks
- Checking for schema drift
- Validating environment configuration
Prerequisites
Required Tools
# Supabase CLI
brew install supabase/tap/supabase
# or: npx supabase / npm i supabase --save-dev (global npm install is NOT supported)
# Verify installation
supabase --version
Environment Variables
Before running scripts, validate credentials with:
python3 .claude/skills/supabase-cli/scripts/validate_env.py
Required variables:
| Variable | Description | Required For |
|---|---|---|
SUPABASE_URL |
Project URL | All operations |
SUPABASE_ANON_KEY |
Public/anon key | Client operations |
SUPABASE_SERVICE_ROLE_KEY |
Service role key | Admin operations |
POSTGRES_DB |
Direct PostgreSQL URL | Migrations, SQL |
SUPABASE_ACCESS_TOKEN |
CLI access token | supabase link, db push, gen types |
Getting the Supabase Access Token
The access token is required for CLI operations like linking projects, pushing migrations, and generating types.
How to get your token:
- Go to https://supabase.com/dashboard/account/tokens
- Click "Generate new token"
- Give it a name (e.g., "CLI Development")
- Copy the token (starts with
sbp_)
How to use it:
Option 1: Store in .env.local (recommended for projects):
# .env.local (add to .gitignore!)
SUPABASE_ACCESS_TOKEN=sbp_your_token_here
Option 2: Export in terminal session:
export SUPABASE_ACCESS_TOKEN="sbp_your_token_here"
Option 3: Interactive login (opens browser):
supabase login
Link your project (required before pushing migrations):
# Extract project ref from your SUPABASE_URL (the subdomain)
# Example: https://abcdefghijkl.supabase.co → project ref is "abcdefghijkl"
supabase link --project-ref <your-project-ref>

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.
- 7d ago First seen · 264 lines · 33 tokens per session scan A 0dda629ec3a3
supabase-cli is a skill published in the GitHub repository georgekhananaev/claude-skills-vault (28 stars, last pushed 29d ago), licensed MIT. It adds 33 tokens to every session and 1,927 once invoked, about $0.0002 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.
