What changed, when, and why.
Every account now gets 120 free checks per day, automatically. No trial, no expiry. After 120, each check costs $0.0068 AUD from your prepaid balance. We also hardened rate limiting across the board — per-key, per-IP, per-device.
AI agents don't see your environment. They don't know which branch deploys to production. They don't know how your CI pipeline is wired. They don't know what's running on which port, or what your Cloudflare Pages project considers "production" vs. "preview." They operate on what you tell them and what they can read from files in front of them — everything else is a guess.
This is not a flaw in any specific model. It's structural. An AI agent can execute a deployment command correctly and still deploy to the wrong place, because it has no visibility into the external systems that determine where "the right place" actually is. The command succeeds. The outcome is wrong. The agent doesn't know the difference.
Check validates what your AI writes against what exists in your project. But the broader point stands: AI agents are blind to anything outside the files they can read. Config that lives in a dashboard, a branch mapping, a DNS rule, a deploy target — none of that is visible to the model. If your workflow depends on knowledge that isn't in the codebase, the AI will not have it unless you provide it.
We're not responsible for what your AI agent can't see. Nobody is. That's the gap.
We moved all the heavy lifting off your machine. Check is faster, more accurate, and you don't need to update anything locally. Just install and go.
Commands still get validated before they run. Code still gets validated after every write. Both happen automatically — nothing changed on your end.
Install: npx @golproductions/check --install your_key
Before this, Check only validated commands before execution. Now it also validates code after every file write — imports, function calls, and syntax are compared against your actual project.
Two checkpoints. Both set up automatically when you install.
Install: npx @golproductions/check --install your_key
This was a full rewrite. Every command your AI generates is now validated before it runs. If something doesn't match your project, it gets flagged before execution.
Every account now gets 120 free checks per day, every day. After 120, each check costs $0.0068 AUD from your prepaid balance. Credits never expire.
Install: npx @golproductions/check --install your_key
Every verdict is logged. You can see how many checks passed, how many got flagged, and what's happening across your sessions. Nice to finally have visibility into this.
You can now install Check across all your IDEs with a single command. It auto-detects Claude Code, Antigravity, and Cursor.
Also fixed a bug on Windows that was causing checks to fail intermittently. Should be smooth now.
Check v1.1.0 works with Claude Code, Antigravity, and Cursor. It figures out which one you're using and just works.
If you're on something else, the API is open for any platform or custom pipeline.
We stripped Check down to one thing: a firewall that sits between your AI and your project. It runs before every command and after every write. Your AI can't skip it or opt out.
One mechanism, done well. That's the whole product now.
