neon

neon is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 44 tokens per session (1,017 once invoked), scanned A, original, MIT.

A hosted, serverless PostgreSQL database, meaning standard PostgreSQL with managed compute, storage, and database branching.

In plain words
What is it for?
Use it for serverless applications, pull-request test databases, and PostgreSQL projects that need temporary development copies.
Why use it?
It can reduce costs for environments that are idle and lets developers create separate database branches for testing. Connection pooling supports serverless functions.

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

neon 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 24d 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.

Neon

Neon is a serverless open-source PostgreSQL database. It separates storage and compute to offer features like "Scale to Zero", "Instant Branching", and "Bottomless Storage".

When to Use

  • Serverless PostgreSQL: Modern PostgreSQL with decoupled storage and compute, scaling down to zero when idle to eliminate costs.
  • Database Branching for Previews: Instantly branching production databases in milliseconds for CI/CD pipelines, staging, and pull requests.
  • Autoscaling Relational Workloads: Automatically scaling compute CPU and RAM dynamically during traffic spikes without connection dropouts.
  • Edge Computing & Serverless Functions: Connecting via WebSockets and HTTP drivers from Cloudflare Workers, Vercel, and AWS Lambda.

Quick Start

// Connect to Neon using the serverless driver over WebSockets / HTTP
import { neon } from "@neondatabase/serverless";

const sql = neon(process.env.DATABASE_URL);

async function getUsers() {
  const users = await sql`SELECT id, name, email FROM users LIMIT 10`;
  return users;
}

Core Concepts

Separation of Compute and Storage Architecture

Stateless PostgreSQL compute nodes query a custom, distributed, multi-tenant storage engine backed by cloud object storage:

[ Stateless Postgres Compute Node ] ──Page Service Protocol──→ [ Distributed Storage Engine ]
                                                                        │ (LSM Tree)
                                                                        ▼
                                                             [ Immutable Cloud S3 ]

Copy-on-Write Database Branching

Creates instant, isolated point-in-time database clones using copy-on-write storage:

# Create a fresh database branch from production using Neon CLI
neon branch create --name pr-415-preview --from main
# Creates an isolated, fully functional Postgres instance in 500ms!

Serverless Driver over WebSockets / HTTP

Bypasses TCP connection handshake overhead from serverless environments:

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.

neon is a skill published in the GitHub repository G1Joshi/Agent-Skills (15 stars, last pushed 25d ago), licensed MIT. It adds 44 tokens to every session and 1,017 once invoked, about $0.0002 per session on Opus 5.5. 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.
