anthropics/claude-tag-plugins is a collection of plugins that connect the Claude coding agent to SaaS services such as task trackers, databases, monitoring systems, and document platforms. Each plugin focuses on one service, so workspaces can enable the integrations they use.
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.

claude-tag-oncall 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.
What it actually says
{
"name": "claude-tag-oncall",
"version": "0.1.0",
"description": "Oncall for @Claude Tag in Slack. Set up once, then Claude watches the team's alert channels and sorts signal from noise, investigates incidents and customer-reported problems (starting on its own when an outage hits), posts sitreps and postmortems, runs the rotation handoff, and drafts fixes for a person to approve.",

}
What it installs
The manifest is a name and a version. 6 skills travel with it, and installing the plugin installs all of them — 2,125 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.
