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.

quality-playbook-harness 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 9d 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 actually says
{
"name": "quality-playbook-harness",
"description": "Orchestrate Quality Playbook runs across multiple repos from one Claude Code session. The harness skill drives a disk-backed state machine via in-session ScheduleWakeup polling: each tick dispatches QPB worker subagents (Task tool), tails their heartbeats, advances the state machine, prints a status table, and reschedules — until every run reaches a terminal state or you write a STOP file. No external scheduler, no long-running daemon; the same ScheduleWakeup primitive the v1.5.7 watcher has run reliably for weeks.",

What it installs
The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 157 tokens a session between them. Each is measured on its own page, and each can be installed alone.
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.
