harness-ops

harness-ops is a plugin for Claude Code from melodic-software/claude-code-plugins. Its manifest loads nothing; the 14 skills it bundles cost 1,386 tokens per session together, scanned A, original, MIT.

A Claude Code operations toolkit for inspecting installed skills, commands, tools, plugins, permissions, and related configuration. Its skills use audits and repository information to explain what is available and how it is configured.

What is it for?
It is for inventorying the coding-agent setup, checking skill visibility and configuration, and investigating operational gaps.
Why use it?

Security

Grade A, and why

harness-ops 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 yesterday.

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.
