@Brammflakes appreciate the transparency!

@GJarrosson I redact in memory before writing an event to disk. Command output is checked twice, environment variables aren’t recorded by default, and stored records are scanned for anything missed.

[Justen @xjstxn]

@GJarrosson Secrets are never stored! Only evidence of successes, failures, patterns, etc. very structured envelopes of session tool calls, and evidence of each.

@warpdotco I will be applying, but I’d also like to submit myself here for consideration so my application is not missed!

Since others are sharing their projects submitted for @FactoryAI Guild applications, I'd like to introduce my favorite and most used item I have built.

AgentDir is an invisible local memory solution, with Vector search. Each agent session records successes, failures, and patterns while you work for later recollection and reference.

It works cross-agent / cross-provider, and has significantly upgraded my local workflow, as well as many other engineers.

@sonofalli My right pinky lifts off the keyboard when I type, does that count?

Just applied for @FactoryAI 's Guild!

Crossing my fingers. This would be an excellent opportunity to showcase some of the unique things I have built for agentic work

@mercury Ordered mine! Fantastic design.

@warpdotco Would you consider remote / hybrid for senior / staff level engineers?

I have two kids and would hate to relocate them, but am very interested!

Introducing Grok 4.6.

It delivers frontier intelligence and is a significant improvement over Grok 4.5 at the same price.
