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.

capacitor-app-upgrades 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 13d 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. 7 skills travel with it, and installing the plugin installs all of them — 1,572 tokens a session between them. Each is measured on its own page, and each can be installed alone.
- Skill capacitor-uiscene-migration A 208 tokens
- Skill capacitor-app-upgrade-v7-to-v8 A 242 tokens
- Skill capacitor-app-upgrade-v8-to-v9 A 271 tokens
- Skill capacitor-app-upgrade-v4-to-v5 A 207 tokens
- Skill capacitor-app-upgrade-v5-to-v6 A 229 tokens
- Skill capacitor-app-upgrade-v6-to-v7 A 240 tokens
- Skill capacitor-app-upgrades A 175 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.
