Logic bug
Change the port from 3000 to 8000 to match the exported port in the tests. The CI test is failing because it expects the server to run on port 8000.

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'.

Konrad Komorowski

Software Engineer, Isometric

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.

Brian Michel

Software Engineer, The Browser Company

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.

Mike Deeks

Infra Engineer, Braintrust

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.

Saket Gejji

CTO, Game Theory

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

Ruven Chu

Software Engineer, Goody

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.

Ali Andaç

Software Engineer, Lasso MD

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.

Reggie Escobar

Software Engineer, Soar Energy Solutions

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

Adam Walker

Co-Founder & CEO, Voxel Games

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.
