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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00088 | $0.02434 |
| Opus 5 | $0.00044 | $0.01217 |
| Sonnet 5 | $0.00018 | $0.00487 |
| Haiku 4.5 | $0.00009 | $0.00243 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Supabase
Supabase is an open-source Firebase alternative that provides a Postgres database, authentication, instant APIs, edge functions, real-time subscriptions, storage, and vector embeddings.
Research Process
To answer questions about Supabase, spawn a sub-agent to conduct thorough documentation research.
Launch a Research Sub-Agent
Use the Task tool to spawn a sub-agent dedicated to Supabase documentation research. Do NOT specify a model (use the default model for comprehensive research quality).
Critical: Provide the sub-agent with a highly detailed prompt that includes:
- Goal - What you are ultimately trying to accomplish
- Context - Why you need this information and how it fits into the larger task
- Specific Questions - Exactly what information you need answered
- Output Requirements - The format and level of detail needed in the response
Task Tool Configuration
Task tool parameters:
- description: "Research Supabase docs"
- subagent_type: "generalPurpose"
- model: (DO NOT SPECIFY - use default for thorough research)
- readonly: true
- prompt: (see template below)
Prompt Template for Sub-Agent
Structure your prompt to the research sub-agent as follows:
You are researching Supabase documentation to help with a specific task.

4. Fetch multiple relevant pages in parallel using WebFetch.
## Required Output
[Specify exactly what format and content you need returned]
Provide a comprehensive response with all findings, including relevant code examples, configuration snippets, and step-by-step instructions where applicable.
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 miketromba/skills (2 stars, last pushed 12d ago), licensed MIT. It adds 88 tokens to every session and 2,434 once invoked, about $0.0004 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 2026-08-31.
