Wellworn, the pre-flight check for coding agents

wellworn.dev Observed source

Editorial interest 85/100 Selection signal · not a rating of the site

A judgment layer that recommends libraries, design systems, open-source tools, and documentation before an agent uses them.

Landing page captured for the 2026-09-10 issue.

Field notes

Wellworn routes agent requests through an MCP server and can also run from a Claude Code hook when package-install commands or dependency manifests change. Its answer format is deliberately constrained: a pick, one alternative, version-specific traps, provenance, and an expiry date, within 3,200 characters. The visible catalog covers 28,242 open-source tools, while the design index lists 22 systems; the Skills section currently reports no published entries.
