It’s a loop. Run your agent, feed the traces to HALO, get the report, apply the fixes, then re-run your agent.

HALO takes in OTEL compliant traces from AI agents using tracing frameworks such as Langfuse, Arize/OpenInference, or even just plain JSONL. It uses an RLM (Recursive Language Model) to more efficiently break trace analysis into smaller subproblems in order to find recurring patterns across large amounts of data and fix systemic issues that regular LLMs might typically miss.

You can also optionally provide a path to where your agent code lives to give the engine more context so it can more concretely provide useful insights.

The repo also includes a desktop app that you can run locally without having to sign up for anything or configure anything complex.

Check out the readme in the repo for more in depth information on what HALO is and how you can use it to your benefit :)

I built an open-source WYSIWYG TikZ editor (available for web and desktop) that allows you to edit your TikZ source code visually by dragging and resizing elements. It simultaneously shows the source code and the rendered figure, and lets you edit either one while the two views stay in sync. I’m not aware of any other editors that are simultaneously source editors and WYSIWYG (even for editing SVG or HTML), and I’m quite pleased with how well the combination works.

The way the app is implemented is by parsing the TikZ code, and at all times keeping track of the exact source location of each object. Thereby, when a user drags an element to a new position, the app can override just the numbers in the coordinate without changing anything else in the code (such as line breaks or indentation).

This approach essentially required reimplementing a large fraction of TikZ, which is the kind of task that no human would ever want to do. I think building software that doesn’t exist yet because it would be impossibly tedious to code up is one of the great new possibilities thanks to coding agents, and it’s worth brainstorming for other examples. (This app was built almost entirely by Codex.)

Implementing the app came with lots of fun side quests, including building converters from SVG / pptx / ipe to TikZ, re-implementing the LaTeX hyphenation and line-breaking algorithm to support multi-line nodes, and making a color picker that uses the red!20!black color mixing notation used in LaTeX papers.

Since then we've released a variable v2 (2022) and now we're happy to expand the typeface with a new family called MonoLisa Text. The reasoning was to cover *other* use cases beyond coding with this proportional font.

We hope you give Monolisa a go as there's a free trial to try. We also welcome feedback!
