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 | $0.00076 | $0.01859 |
| Opus 5 | $0.00038 | $0.00929 |
| Sonnet 5 | $0.00015 | $0.00372 |
| Haiku 4.5 | $0.00008 | $0.00186 |
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 6d 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.

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

Neon Serverless Postgres
Neon is a serverless Postgres platform that separates compute and storage to offer autoscaling, branching, instant restore, and scale-to-zero. It's fully compatible with Postgres and works with any language, framework, or ORM that supports Postgres.
When to Use This Skill
Activate this skill when users want to:
- Create or manage a Postgres database
- Set up a Neon project or branch
- Connect an application to Neon Postgres
- Use Neon features like branching, autoscaling, or scale-to-zero
- Set up Neon Auth for user authentication
- Use the Neon MCP server, CLI, or API
- Work with the
@neondatabase/serverlessdriver or@neondatabase/neon-jsSDK
Prerequisites
The Neon MCP server is required for project and database management. It uses OAuth and authenticates via browser on first use — no API key needed.
If MCP tools are not available, guide the user through manual setup:
Codex
The Neon MCP server should be configured automatically via this plugin. If it isn't, the user can add it manually:
codex mcp add neon --url https://mcp.neon.tech/mcp
Restart Codex, then verify by attempting to list projects.
Other Tools
Direct the user to the Neon MCP docs for setup steps: https://neon.com/docs/ai/neon-mcp-server
Neon Documentation
The Neon documentation is the source of truth for all Neon-related information. Always verify claims against the official docs before responding. Neon features and APIs evolve, so prefer fetching current docs over relying on training data.
Fetching Docs as Markdown
Any Neon doc page can be fetched as markdown in two ways:
- Append
.mdto the URL (simplest): https://neon.com/docs/introduction/branching.md - Request
text/markdownon the standard URL:curl -H "Accept: text/markdown" https://neon.com/docs/introduction/branching
Both return the same markdown content. Use whichever method your tools support.
Finding the Right Page
The docs index lists every available page with its URL and a short description:
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-postgres is a skill published in the GitHub repository fanfan-de/anybox (57 stars, last pushed 27d ago), licensed MIT. It adds 76 tokens to every session and 1,859 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 89% identical to neon-postgres, differing in 37 lines, and is treated as a copy.
