32,774 stars, split into /plugins for Anthropic-maintained entries and /external_plugins for partner and community submissions entering through a review form. Two details if you publish: plugin name slugs are immutable once published (use displayName for UI labels and a renames map in marketplace.json for unavoidable changes), and Anthropic states directly that users must trust plugins before installing because it doesn't control which MCP servers or files get bundled. 841 open issues suggests submission volume is outpacing review throughput, which is exactly the condition that produces a bad install.

The .github/workflows directory holds bump-plugin-shas.yml, owner-liveness-sweep.yml, validate-plugins.yml and close-external-prs.yml, and the commit history shows them doing real work (GitHub). An August 19 commit added a deterministic static pin check for auto-exec MCP launc...
Frontier labs publish demos. This one published the thing they actually page. Anthropic's August 18 writeup describes Claude Tag running as the first responder for CI failures inside the company. Dedicated service account. MCP connectors to Datadog, Grafana, PagerDuty, GitHub...
Three separate Anthropic changes over about two weeks point the same direction, and none of them announced themselves as a strategy. Claude Code 2.1.238 added claude self-hosted-runner --defer-shutdown-max-min, which keeps serving attached sessions on SIGTERM, parks whatever's...
A spec is a press release until someone who didn't write it implements it. GitHub made Agent Plugins 1.0 generally available on August 12 across VS Code, Copilot CLI, the Copilot SDK, and the Copilot app on all plans. The spec, published August 6, was co-authored by AWS, Anysp...
Six clients. One manifest. Zero vendor lock. Vercel published Agent Plugins 1.0.0 on August 6, an openly licensed spec that bundles Agent Skills and MCP servers behind a single portable manifest. The shape is deliberately boring: a plugin.json requiring only schemaVersion and...
Anthropic invented a file convention. It's now shipping GA inside a competitor's product. Nobody wrote a spec, nobody held a standards meeting, it just happened. On July 29, GitHub made agent skills and MCP server support generally available in Copilot code review for all Pro,...
