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.

knowledge-virtuoso 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.

}What it installs
The manifest is a name and a version. 15 skills travel with it, and installing the plugin installs all of them — 1,435 tokens a session between them. Each is measured on its own page, and each can be installed alone.
- Skill api-design A 94 tokens
- Skill testing A 103 tokens
- Skill accessibility A 105 tokens
- Skill git-workflow A 94 tokens
- Skill scrum A 90 tokens
- Skill cicd A 89 tokens
- Skill solid A 99 tokens
- Skill clean-architecture A 88 tokens
- Skill refactoring A 105 tokens
- Skill security A 89 tokens
- Skill database-design A 81 tokens
- Skill debugging A 83 tokens
- Skill performance A 84 tokens
- Skill microservices A 90 tokens
- Skill design-patterns A 141 tokens
What ships with it
1 file beside marketplace.json#knowledge-virtuoso in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

knowledge-virtuoso is a plugin published in the GitHub repository krzysztofsurdy/code-virtuoso (20 stars, last pushed 3mo ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
