estate-guard is a skill for Claude Code from frankxai/agentic-ops-hub. It costs 112 tokens per session (1,307 once invoked), scanned D, original, no licence file.

A security review gate for repositories that contain coding-agent settings, automation, installation scripts, or selected web API routes. It checks the parts of a repository where agent behavior and execution are configured.

In plain words
What is it for?
Reviewing or hardening agent-related repositories, especially before opening a pull request that changes workflows, agent files, MCP settings, install scripts, or Next.js API routes.
Why use it?
It helps identify prompt injection and other security risks before changes to sensitive files are submitted for review.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is frankxai/agentic-ops-hub's own configuration. It tells Claude Code how to work on agentic-ops-hub itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentic-ops-hub configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node .claude/ci/estate-guard-scan.mjs --root . --fail-on never # markdown report.

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 D, and why

estate-guard scanned grade D with 5 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 23d 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.

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

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

A mod that escalates privileges can change anything on the machine, not only the project.

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.
