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 | $0.00029 | $0.03989 |
| Opus 5.5 | $0.00012 | $0.01596 |
| Sonnet 5.5 | $0.00006 | $0.00798 |
| Haiku 4.5 | $0.00003 | $0.00399 |
Grade A, and why
neon-postgres 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 2d 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.
This is a copy
95% identical to neon-postgres — 388 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 295 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lakebase Postgres
Local Scope and Authorization
Use existing authorized Neon connections and the user's supplied DATABASE_URL or linked .neon project first. Do not create a second project, replace an ORM, install a CLI, or start an authentication flow merely because this skill was loaded. Use tools actually available in the current host; optional neon, neon-auth, and branch skills are separate capabilities, not assumed installed dependencies. Installer commands below are examples only for an explicitly requested setup.
Lakebase Postgres is the database at the core of Neon. It runs on the lakebase architecture — OLTP built directly on cloud object storage — which decouples storage from compute 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.
It is the same database whether you reach it through Neon or through Databricks; this skill covers the Neon access path.
Login, users, sessions, and @neon/auth belong in neon-auth.
Live queries, reactive UIs, and realtime data belong in neon-realtime.
Setup Flow
1. Select the organization and project
If a DATABASE_URL is already supplied (prompt, environment, or repo) or a .neon file points at a project, use it. Do not list organizations or create a second project for schema work.
Otherwise use the CLI (default) or MCP server to list organizations and projects. Let the user select an existing project or create a new one.
2. Get the connection string
If a DATABASE_URL is already supplied, use it. Do not fetch another through the CLI or MCP.
Otherwise use the CLI (default), neon env pull, or the MCP server to get the connection string. Store it in .env as DATABASE_URL. Read the file first before modifying it, to avoid overwriting existing values.
When to use pooled vs direct connections
| Use case | Connection type |
|---|---|
| Web applications, serverless functions | Pooled (-pooler) |
| Schema migrations | Direct |
| pg_dump / pg_restore | Direct |
| Logical replication | Direct |
| Long-running analytics with temp tables | Direct |
| Admin tasks needing SET or session state | Direct |
| LISTEN / NOTIFY | Direct |
What ships with it
6 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 seaworld008/Commonly-used-high-value-skills (74 stars, last pushed 2d ago), licensed MIT. It adds 29 tokens to every session and 3,989 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 95% identical to neon-postgres, differing in 388 lines, and is treated as a copy.
