Solid, with a learning curve

Took about a week to tune the config to our repo's conventions, but once it clicked it's been reliable. Wouldn't hand it the riskiest changes unsupervised yet.

Pros
  • Good defaults
  • Responsive to feedback
Cons
  • Setup docs assume more context than we had

Useful but needs guardrails

Works well for the narrow case we use it for. We had to add explicit boundaries after it did something a bit too enthusiastic in week one.

Pros
  • Capable when scoped well
Cons
  • Needs explicit boundaries
  • Support response was slow

Exactly what we needed

Replaced a manual process that was eating an hour a day across the team. Straightforward to configure and it's held up under real usage.

Pros
  • Saves real time weekly
