OpenMod Lab — a workbench for Claude Code mods
A browser-based lab for editing JavaScript hooks, replaying simulated tool events, inspecting capabilities, and downloading a Claude Code plugin.
- For
- Claude Code mod builders and reviewers
- Worth noticing
- The replay uses synthetic events, while source evaluation runs in a disposable worker inside a sandboxed frame with network access blocked and a two-second deadline.
Field notes
The replay is deliberately bounded: tool results and timings come from fixtures, and unsupported APIs fail explicitly. The capability lens checks literal registrations and API calls, which the page distinguishes from a security audit. The project reports that its three bundled plugins pass the official validator; Flight Recorder also has four native tests. The page identifies the project as an independent experiment by Jerry Wang, not affiliated with Anthropic.
