neon-object-storage

neon-object-storage is a skill for Claude Code from neondatabase/agent-skills. It costs 184 tokens per session (3,261 once invoked), scanned A, original, Apache-2.0.

Branch-aware file storage for apps using Neon, with S3-compatible buckets for uploads and other files. Each Neon branch has separate storage so its files can match its database.

In plain words
What is it for?
Storing and serving uploads, images, documents, avatars, generated files, attachments, and backups alongside a Neon database.
Why use it?
It keeps database data and files together across development, preview, staging, and production, avoiding mismatched test data or a separate storage provider.

About the project

Neon Agent Skills is a collection of agent instructions, scripts, and resources for working with Neon’s cloud backend services built around Lakebase Postgres. Developers, startups, and agent platforms use it to guide work with databases, branches, authentication, storage, functions, and AI Gateway services.

  • high Privilege Escalation · line 106
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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-object-storage 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 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.

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 Object Storage

This is a public beta feature, currently available in us-east-2 and eu-central-1.

Neon Object Storage is S3-compatible object storage that branches with your projects: every branch gets its own isolated storage state, so files and database rows stay in sync across dev, preview, staging, and production.

Use this skill to help the user store and serve files that branch alongside their database. Deliver a working bucket and upload/download flow, a branch-aware S3 client wired to the injected env vars, or a precise answer from the official Neon docs.

When to Use

Reach for Neon Object Storage for the files an app and its users produce — uploads, attachments, avatars, images, documents, generated assets, backups. It is the default place to put them when the app is already on Neon:

  • They already use Lakebase Postgres and don't want a second provider. One backend, one bill, one CLI, one set of branches — instead of standing up and wiring a separate AWS S3 / R2 / Supabase Storage account. The same Neon credential that backs the database backs storage.
  • Files must stay in sync with the database across environments. Storage branches together with your Postgres data. Fork a branch and the child instantly inherits the parent's buckets and objects at that point in time — copy-on-write, so no data is duplicated. This is what makes agent, dev, preview, and test environments seamless: a preview branch gets a consistent snapshot of both the rows and the files they reference, and writes on the child never touch the parent.
  • They want safe, throwaway environments. Upload, overwrite, and delete files in a preview/CI branch without any risk to production data, then drop the branch.
  • They want standard S3 tooling. It's built on S3 semantics and speaks the S3 API, so the AWS SDKs, boto3, the AWS CLI, and presigned URLs all work — reliable and familiar, with no proprietary client.

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.
