When to use it

A sequence works technically but feels confusing or untrustworthy.

Before you start

Describe the user goal and follow the entire journey, including waiting and recovery. Separate observed friction from hypotheses about abandonment or satisfaction.

Try this in your coding agent.

/carbon-ux Review the checkout journey for confusing steps and missing feedback.

Replace sample paths with your project. Slash names are shorthand; your host may use a plugin prefix or a skill picker. Invocation help →

ILLUSTRATIVE WALKTHROUGH

Checkout feedback

An expanded teaching example, not a recorded or live execution. The report stays visible while the replay explains how to read it.

Coding-agent conversation

Read context

I’m reviewing checkout feedback. I’ll keep the scope and permissions explicit.

Investigate

Follow the weakest evidence link and record what remains blocked.

Show evidence

Here is the evidence trail to inspect: Submit → waiting state has no progress message → repeated action becomes likely.

Report

A slow response leaves users unsure whether the order was submitted. Behavioral impact is a hypothesis until studied with users.

Example report

Illustration
Failure → evidence → recovery
Failure → evidence → recovery — TestBucks teaching screen

TestBucks course screen with illustrative analysis. The screenshot supplies context; the demo does not establish a newly observed bug.

  1. Failed request
  2. Preserved state
  3. Safe retry

Illustrated outcome

A slow response leaves users unsure whether the order was submitted.

Evidence to inspect

Submit → waiting state has no progress message → repeated action becomes likely.

Still untested / not established

Behavioral impact is a hypothesis until studied with users.

Ready. Read the full example or play its steps.

What a useful result contains

A bounded claim

For checkout feedback, state the target, revision, environment and actual work performed. Keep planned, executed, blocked and untested work separate.

An inspectable trail

Submit → waiting state has no progress message → repeated action becomes likely. In a real run, retain the source, trace, screenshot or fixture behind the conclusion.

The qualification

Behavioral impact is a hypothesis until studied with users.

The next decision

Decide whether the evidence calls for a focused check, a reviewed fix or more context. Do not convert a plausible example into a verified finding.

Adapt the example to your project

  1. Replace checkout feedback with a real feature, path or decision in your project.
  2. State the expected rule and its source. Include safe fixtures, constraints and a budget where appropriate.
  3. Ask for exact evidence and remaining gaps. Approve consequential actions separately.
/jay Review the /carbon-ux result. Separate observed evidence, assumptions and untested scope, then recommend the next useful check.
