Sentry-compatible error tracking CLI designed for AI agents, not humans.

Strengths
  • •Sentry SDK compatibility means zero backend infra changes.
  • •CLI-first design matches how agents actually operate.
  • •JSON stdout makes piping into other agent tools trivial.
Weaknesses
  • •Extremely early stage with zero stars and minimal documentation.
  • •No dashboard means humans still lack visibility into agent errors.
Target Audience

Post Description

Hi HN,

walnut is an error tracker that is built for agents instead of humans

There is no dashboard. Just a cli that agents can use to do everything, including signing up and reading docs.

walnut is fully Sentry sdk compatible, so it works with existing sentry setups just by changing the dsn.

To try it, paste this prompt into your coding agent:

###

Set up walnut.

Install the cli first: `curl -fsSL https://walnut.sh | bash`

Then use `walnut docs list` and `walnut docs read <slug>` to learn the rest.
