infra-validator

infra-validator is an agent for coding agents from berrzebb/quorum. It costs 30 tokens per session (279 once invoked), scanned A, original, MIT.

A reviewer for deployment and operations files, including Dockerfiles, continuous integration and delivery settings, environment variables, and deployment configuration.

In plain words
What is it for?
Use it to scan container files, CI/CD configuration, environment-variable handling, and other project infrastructure.
Why use it?
It finds infrastructure security and deployment risks that may not appear in application-code review. It also avoids treating development-only settings as production problems.

Agent

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the quorum plugin — 10 commands, 13 agents shipped together

Install

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.

agentmods
npx agentmods add agents/berrzebb/quorum/infra-validator
Clone the repo
git clone --depth 1 https://github.com/berrzebb/quorum

Or install quorum, the plugin that ships this one along with the rest of its 10 commands, 13 agents.

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

infra-validator 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 3d 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.

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.
