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.
/plugin marketplace add Connorrmcd6/vibe-specnpx agentmods add plugins/connorrmcd6/vibe-spec/vibe-specgit clone --depth 1 https://github.com/Connorrmcd6/vibe-specGrade A, and why
vibe-spec 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.

A 5-step /spec-* workflow (draft, refine, phases, plan, implement) plus /spec-setup, /spec-doctor, and /spec-troubleshoot for environment setup, /spec-secrets for redacted secret-leak auditing, and a vibe-spec skill with 21 on-demand stack references (Next.js, Prisma, Auth, RBAC, dbt, CI/CD, secrets, doc governance, prerequisites, and more).",

What it installs
The manifest is a name and a version. 1 skill, 9 commands travel with it, and installing the plugin installs all of them — 531 tokens a session between them. Each is measured on its own page, and each can be installed alone.
- Skill vibe-spec A 109 tokens
- Command spec-plan A 49 tokens
- Command spec-phases A 35 tokens
- Command spec-secrets A 57 tokens
- Command spec-doctor A 51 tokens
- Command spec-implement A 36 tokens
- Command spec-refine A 49 tokens
- Command spec-setup A 55 tokens
- Command spec-draft A 40 tokens
- Command spec-troubleshoot B 50 tokens
What ships with it
1 file beside plugin.json 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.
