trustwarden

trustwarden is a plugin for Claude Code from revenantworks/claude-skills. Its manifest loads nothing; the 1 skill it bundles cost 165 tokens per session together, scanned A, original, Apache-2.0.

A security review tool for third-party coding add-ons, tool servers, and GitHub Actions. It gives a verdict such as pass, conditional, hold, or fail and states the terms for installation.

In plain words
What is it for?
It helps review new installations, plugin updates, MCP servers, GitHub Actions, and licence or installer changes before they enter a project.
Why use it?
It helps decide whether external code is safe to install instead of relying only on a scanner's clean result. It also highlights files that scanners or the review did not inspect.

Security

Grade A, and why

trustwarden 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 5d 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 it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 165 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

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.
