It's different from other AI tools because... it actually works. It doesn't blindly say 'hey here's a typo,' it gives well reasoned recommendations based on the context of what I'm trying to build and what I'm trying to build it in."

Brian Michel

Software Engineer at The Browser Company

Diamond is very high signal, unlike other tools on the market. It found a months old bug in our codebase, that no human engineer could spot and so far, every highlighted issue has been a real problem."

Konrad Komorowski

Software Engineer at Isometric

Diamond is currently my favorite thing. No fuss, easy to set up, easy to use, super helpful. I inserted our credit card and our lives got better."

Mike Deeks

Infra Engineer at Braintrust

We're seeing it comment on nits that we definitely would have missed, which is fantastic for improving our code quality."

Saket Gejji

CTO at Game Theory

Diamond has been great for us! It does a fantastic job at finding real problems with our code and not delivering a lot of noise."

Ruven Chu

Software Engineer at Goody

Diamond is a handy teammate who checks the PR quickly and saves your hours before merging your change. With this instant boost, development process time could decrease dramatically and ensure code quality level. Suggesting teams who aim for speed."

Ali Andaç

Software Engineer at Lasso MD

It's really fast (it caught things before our CI did). It caught things before PR reviewers did."

Reggie Escobar

Software Engineer at Soar Energy Solutions

I've been using it for two weeks now and have to say, while it has only triggered a handful of times, each time has been an incredibly helpful insight on something I overlooked as well as other members of my team."

Diamond automatically identifies potential issues in your code, so your team can dedicate more time to building and less time to manual reviews.

Logic bug

The condition in the if statement should be inverted. Change it to: if (!Object.keys(ASYNC_JOB_REGISTRY).includes(kind)) {

Potential edge case

readlink -f is not available on macOS by default. A more portable solution would be: bash filepath=$(perl -e 'use Cwd "abs_path";print abs_path(shift)' "$0") This achieves the same result but works across both Linux and macOS environments.

Security issue

Please remove this token logging. Exposing GitHub access tokens in logs creates a security risk, as these tokens grant API access and should be treated as sensitive credentials.

Accidentally committed code

Adding || true to this condition causes the function to unconditionally return "BINARY", bypassing the binary detection logic. This appears to be unintentional and should be removed to restore the original file type detection behavior.

Performance

The await inside Promise.all([...]) is preventing parallel execution of these promises. Since Promise.all expects an array of promises, the await here will cause the stack dependency check to complete before the merge job query begins. To achieve the intended parallel execution, remove the await from db.stack.getStackDependencyForPr().

Code style/quality

The callsite value markNotifAsRead doesn't match the function name markAsReadEndpoint.

Documentation issue

The description 'Get auth tokens for user' doesn't match the command's actual functionality. Consider changing it to 'Run async job queue and send a test email'.
