Implementing a Fuzzier font option using Junie

Collaborating with Junie on implementing font family setting for Fuzzier

On the last PR I let Junie handle all coding. On this one I use my normal collaborative workflow.

  1. Junie: Initial setup - Added the new setting and created tests (normally copy-paste work for me)
  2. Junie: API work - Handled the editor font API call (would’ve been googling/doc-reading for me)
  3. Me: Review & refactor - Went through the changes, tested functionality and did some refactoring
  4. Junie: Code review - Suggested improvements (null safety, caching)
  5. Both: Implementation - Applied the improvements together
  6. Me: Documentation - Updated docs and some minor tweaks (wording etc.)

Full PR - #142.

Evaluation

Prompting

Three tasks with 8 prompts.

Time

I think I saved a bit of time doing this. I avoided having to check how to do certain things in Kotlin and skipped checking the SDK docs.

Friction/Enjoyment

Having Junie handle the initial settings setup made the process feel easier as I could skip the “boring” part.

Quality

The quality was better than it would have been otherwise. The null safety and cache were good additions.

Price

During this whole process I spent 0,70 JetBrains AI credits. I didn’t take any special measures regarding token usage.

With the Pro plan, this converts to 0,70 euros.

Thinking

I feel like I was in control and didn’t approve any changes that I didn’t understand.

Conclusion

Working alongside the agent/chat feels better and I do feel like this the best balance between quality/speed/cost for me.

Again a simple feature with good examples in the codebase.
