About

sindri is a plugin bundle for AI coding tools published by 4KMetrics. Marketplaces we read that list it: 1 (Claude Code: claude-plugins-community). We first saw it on 2026-10-12 and have recorded no change since. As of our marketplace pass on 2026-10-13.

In its own words, on Claude Code: claude-plugins-community:

Sindri turns a one-line goal like "reduce bundle_bytes by 15%" into an autonomous, overnight experiment loop. It proposes candidates,applies them in fresh subagent contexts, runs your benchmark, keeps the wins as git commits, reverts the losses, and opens a PR with a human-readable log. One commit per kept experiment. Git is the audit log.

Found by meaning, not by shared code or a shared repository: similar plugins stay separate products, and this is not a review or a recommendation.

Is this your plugin?

Add it to your projects and prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.

Data comes from the public marketplace file https://github.com/anthropics/claude-plugins-community/blob/HEAD/.claude-plugin/marketplace.json. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
