Meridian: Skill for Claude Code

.agents/skills/neon-postgres/SKILL.md

neon-postgres is a skill for Claude Code, Codex from meridianmcp/Meridian. It costs 151 tokens per session (2,502 once invoked), scanned A, original, no licence file.

A guide to Neon Serverless Postgres, a hosted PostgreSQL database that can scale resources with demand. It covers connections, database branches, scaling, replicas, pooling, authentication, and Neon development tools and interfaces.

In plain words
What is it for?
Use it for Neon setup, application connections, branching, autoscaling, scale-to-zero, read replicas, connection pooling, Neon Auth, and the Neon CLI, APIs, and SDKs.
Why use it?
It helps developers choose and configure the right way to connect to and operate a Neon database. It brings setup and usage guidance into one place instead of requiring separate research.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is meridianmcp/Meridian's own configuration. It tells Claude Code and Codex how to work on Meridian itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Meridian configures →

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-postgres scanned grade A 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 2mo 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Changes

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.
