THE ASSURANCE LOOP

From spec to proof.

One requirement, traced through all four: Users can reset a forgotten password.

1PlanASSURANCE

spec · password reset

JiraConfluenceLineardoc

Reads your spec and lists what must be true. You approve it.

2DesignASSURANCE

reset link is emailed→ AC-1

new password signs in→ AC-2

old password is rejected→ AC-3

Writes one test per scenario, each linked to its requirement. You review them.

3ExecuteEVIDENCE

$ kane-cli testrun run

✓ reset link is emailed

✕ new password signs in

· old password: not run

Runs on your machine or the TestMu AI cloud, and seals the evidence.

AC-2 failed

AC-3○ still open

Shows what's proven, what failed, and what's still open.

When the spec changes, Kane CLI flags every test it affects.

// Why Kane CLI exists

Code ships faster than you can prove it works.

A quick click-through catches the obvious. It leaves nothing the next person can check.

Build. Validate. Prove. Repeat.

Everything your AI coding agent builds should go through this loop. It ends with a confidence score for the build.

the Mobile CLI takes the same plain-English objective as the Web CLI

same pass or fail, same evidence per step

For local runs

A Mac with Apple Silicon
Android Studio or Xcode
Your app build or an uploaded app ID

Without an Apple Silicon Mac, saved tests can run on the TestMu AI cloud, with the remote-execution plugin and a HyperExecute macOS plan.

// Use cases and workflows

What teams can assure with Kane CLI.

Real flows in payments, e-commerce, banking and CRM. Each one is a plain-English sentence and a result Kane CLI has to prove.

Payments

3DS challenge

The 3D Secure step breaks naive automation.

“Pay with a 3DS test card and approve the challenge iframe”

Challenge completes and payment succeeds

Read the use case

E-commerce Found a bug

One-click checkout

Most revenue goes through this path.

“Buy an item with saved address and payment, reach order confirmation”

Order number shown, and the total matches the product page

Read the use case

Banking

Login with 2FA

Every account sits behind this step.

“Log in with the OTP challenge in the test environment”

Dashboard loads with masked accounts

Read the use case

Food delivery

Promo application

A wrong discount costs money on every order.

“Apply a promo and verify the discount math”

Total drops by the promo value

Travel

Instant book checkout

One failed step loses the booking.

“Complete an instant book with a test payment”

Trip confirmed in the trips tab

CRM

Record edit through overlays

Loading overlays break automation.

“Edit an account field and save through loading overlays”

Saved value persists after reload

See the use case library

// From builders

Builders on Kane CLI, in their own words.

𝕏2nd place, Kane CLI Online Hackathon

“My coding agent marked a task done. The chart it built drew the same data twice. So for the @testmuai Kane CLI hackathon I built a gate: Claude Code cannot stop until a real browser agrees. It placed 2nd.”

Abhinav Pangaria

𝕏Kane CLI Online Hackathon entrant

“for the recorded run, Kane caught a real broken task flow. Elenchos sent that evidence back to Gemini, the agent fixed the implementation, and Kane passed every acceptance criterion on the second attempt”

“I wasn’t just asking an AI agent to build an e-commerce application and assuming everything worked. I used Kane as part of the process of checking real user flows in the browser.”

Lammy.Sol

@lammy_sol on X · Sep 1, 2026

“The build-fast, trust-slow gap is very real. I like how Kane CLI focuses not just on running tests, but on producing evidence teams can actually trust and share.”
