• Shipped jev-guard, guardrails that make Claude Code check its claims.
  • Shipped tenx-mess, a skill that cleans up what agents leave behind.
  • Starred simslim and xprem, for more iOS simulators and self-hosted Expo updates.

I shipped two Claude Code tools in these two weeks. Both are public on GitHub.

jev-guard

jev-guard went up on 22 September. It adds probability-scored guardrails to Claude Code. It denies edits that break your rules and deploys you did not ask for. It routes your docs into each prompt. At the end of a turn, it checks the final answer against the evidence from that turn.

The guard sends each check to Jev, a cheap model that answers a question with a probability instead of a yes or no. It challenges Claude’s claims and makes Claude verify what it says before it declares the work done.

tenx-mess

tenx-mess followed on 28 September. Agents ship at 10x speed and leave a 10x mess. This skill finds leftover git worktrees, node_modules, Xcode DerivedData and package caches on macOS. It deletes them only after you approve twice. On the first day I added a confirmation page, so a cleanup now starts from an Approve button.

Starred

simslim lets you run more iOS simulators on one Mac. It turns off background daemons that a simulator does not need. xprem is a self-hosted alternative to EAS Update. It uses the official Expo Updates protocol.
