nest

An autonomous security-testing agent for Nest and Next applications. Nest is a framework for building server applications with JavaScript or TypeScript, while Next is a framework for building web applications.

In plain words
What is it for?
Use it for penetration testing—authorized attempts to find security weaknesses—in applications built with Nest or Next.
Why use it?
It helps test these applications for security problems without requiring every testing step to be performed manually. The input does not specify which tests or findings it produces.

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.

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 B, and why

nest scanned grade B with 3 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.

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

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

- NEVER run parallel curl loops (& ... wait) with more than 3 concurrent workers.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

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.

nest is an agent published in the GitHub repository ASCIT31/Dark-Moon (886 stars, last pushed 3d ago), licensed GPL-3.0. It adds 19 tokens to every session and 8,313 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 3 findings (cloud metadata endpoint, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
