Jay, the AI test manager

MEET YOUR TEST MANAGER

Let Jay decide where to look first.

Jay examines the project and current changes, prioritizes consequential risks, coordinates the available sub-agents and reports back with evidence, trends and a qualified opinion on shipworthiness.

/carbon

No project handy? Create a disposable demo →

One request. In your coding agent.

Install the appropriate CARBON edition in a supported host, open the project and use its command or skill picker. This booklet does not install CARBON or run tests.

Claude

Commands commonly use the plugin prefix, such as /carbon:carbon or /carbon:jay. Use the name shown by your installed plugin.

Codex

Choose the CARBON skill, or use its supported $carbon form. Names and invocation UI are host-controlled.

Other configured hosts

Use the installed integration’s prompt, command or tool picker. A slash shorthand in this guide is not a universal terminal command.

Your access, your limits

Keep your existing frameworks. Your host supplies tools and model access; model usage, credentials and permissions remain under that host’s policies.

Read results, not just green checks.

Observed

A check ran, with a recorded outcome and evidence.

Proposed

A test or fix is suggested. It has not yet established anything.

Blocked / untested

Access, tools or scope prevented execution. Missing evidence is not a pass.

Qualified confidence

A judgment tied to evidence, assumptions and known gaps—not a guarantee of defect-free software.

Contents

/j is an alias for /jay. These 60 chapters cover the current command surface.

CHAPTER 01 / 60 Core + Pro

/carbon

Test a project or verify a recent feature or bug fix with Jay: risk-based checks, reproducible findings and confidence in a visual report.

Jay · Your AI test managerStart & investigate

When to use it

You have a change to validate but do not yet know where testing effort belongs.

Before you start

Give Jay the changed area and the user outcome that must still work. Check that the report distinguishes executed checks from source inspection and deferred risks.

Try this in your coding agent.

/carbon Review my changes in src/checkout and test the highest-risk purchase flow.

Coding-agent conversation

Understand change

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

Rank risk

I’m prioritizing incorrect totals and lost cart state before cosmetic differences.

Run checks

Run checks: Review my changes in src/checkout and test the highest-risk purchase flow.

Reproduce

Here is the evidence trail to inspect: Cart: coffee + mug → apply MUG10 → remove mug → discount remains.

Report

A discount survives after its eligible item is removed. Payment-provider behavior is outside this local example.

Evidence to inspect

Cart: coffee + mug → apply MUG10 → remove mug → discount remains.

Still untested / not established

Payment-provider behavior is outside this local example.

Ready. Read the full example or play its steps.

What a useful result contains

A bounded claim

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

An inspectable trail

Cart: coffee + mug → apply MUG10 → remove mug → discount remains. In a real run, retain the source, trace, screenshot or fixture behind the conclusion.

The qualification

Payment-provider behavior is outside this local example.

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 changes 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.

CHAPTER 02 / 60 Core + Pro

/jay

Talk directly to Jay, CARBON's AI test manager: ask questions, discuss evidence, choose what to test, or request an assessment.

Jay · Your AI test managerStart & investigate

When to use it

You want a testing conversation: what matters, what happened, or what to investigate next.

Before you start

Ask a question to discuss evidence, or explicitly ask Jay to test a target. A conversation does not silently authorize tests or fixes. /j is the same entry point.

Try this in your coding agent.

/full

Run CARBON's comprehensive, resumable testing campaign with Jay, parallel specialists, broad risk-ranked coverage, verified and triaged findings, and a live report.

Jay · Your AI test managerStart & investigate

When to use it

You need a coordinated campaign rather than a bounded first look.

Before you start

Identify the project and optional time limit. Two separate confirmations precede testing. Check the campaign checkpoints, blocked environments and cumulative evidence, then resume deliberately if interrupted.

Try this in your coding agent.

/carbon-accessibility

Run focused CARBON Accessibility testing and generate branded accessibility, WCAG 2.2, and VPAT 2.5Rev-aligned Accessibility Conformance Report artifacts.

Alejandro · AccessibilityExperience & accessibility

When to use it

You need contextual accessibility evidence beyond simple rules.

Before you start

Include keyboard and focus flows, text resizing and reflow, contrast, and whether alternative text conveys useful meaning. Request WCAG A/AA and relevant AAA coverage, a draft VPAT/ACR, and company/location context for legal-exposure triage. Human review is still required.

Try this in your coding agent.

/carbon-accessibility Check the sign-in form for keyboard access, text resizing and useful labels.

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

Beyond a rules-only scan.

Meaning

Is the alternative text accurate and useful in context—not merely present?

Dynamic experience

Can people complete the flow with keyboard navigation, resized text and reflow?

Reviewable reporting

Map evidence to WCAG A/AA and relevant AAA criteria. Produce a draft VPAT-aligned ACR with unresolved criteria visible.

Exposure triage

Use company type, location and product context to frame potential legal exposure for expert review. This is not legal advice or certification.

CHAPTER 33 / 60 Pro

/proof

Automatically select a consequential code property and attempt bounded local Lean verification with CARBON.

Jay · Your AI test managerProof & release confidence

When to use it

A consequential code property has a small, supported formal scope.

Before you start

Bare /proof ranks source-grounded candidates and attempts one supported property automatically. Lean is required. Toolchain installation needs approval. Supported restricted Python Boolean and finite JavaScript state-transition models are not general proofs of arbitrary application code.

Try this in your coding agent.

/proof Inspect src/orders/state.js and attempt a Lean-backed proof of our documented order-transition rules. Keep unsupported behavior explicit.

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

Read the verdict precisely.

PROVED
The recorded model property holds in its stated domain under its assumptions.
COUNTEREXAMPLE
A concrete failure has replay evidence. Preserve the input and regression fixture.
UNPROVED
Unsupported semantics, missing Lean/isolation, unresolved obligations or budget exhaustion. Not automatically a bug.
STALE
The fingerprint or dependencies changed. Fresh preparation and checking are needed.

Lean is mandatory: no native-only fallback. New toolchain downloads/container setup need explicit permission. Default automatic verification is one bounded attempt; manual selection is opt-in. A successful setup or generated Lean file is not a proof result.

Illustrative Lean: a tiny status model

This teaching example is not runtime-generated output or proof of the application. It only demonstrates the shape of a narrow model claim.

inductive Status where
  | pending | paid | shipped | cancelled
  deriving DecidableEq

def allowed (a b : Status) : Bool :=
  match a, b with
  | .pending, .paid => true
  | .pending, .cancelled => true
  | .paid, .shipped => true
  | _, _ => false

A bounded claim

For support-assistant release gate, state the target, revision, environment and actual work performed. Keep planned, executed, blocked and untested work separate.

An inspectable trail

Map blocking findings to release criteria, owner actions and remaining uncertainty. In a real run, retain the source, trace, screenshot or fixture behind the conclusion.

The qualification

The demo makes no real release decision.

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 support-assistant release gate 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.

CHAPTER 40 / 60 Pro

/carbon-release-review

Independently synthesize code, evals, risk, production signals, severe failures, rollback readiness, evaluator independence, and uncertainty into a scoped AI release recommendation.

Jay · Your AI test managerProof & release confidence

When to use it

A release recommendation needs an independent challenge.

Before you start

Give the reviewer the underlying evidence, not only the optimistic summary. Check freshness, severity, evaluator independence and rollback readiness in a separate review context.

Try this in your coding agent.

Evidence to inspect

Candidate: expired token is rejected, password unchanged, helpful recovery link visible.

Still untested / not established

Generated tests still need execution and review.

Ready. Read the full example or play its steps.

What a useful result contains

A bounded claim

For password-reset regression candidates, state the target, revision, environment and actual work performed. Keep planned, executed, blocked and untested work separate.

An inspectable trail

Candidate: expired token is rejected, password unchanged, helpful recovery link visible. In a real run, retain the source, trace, screenshot or fixture behind the conclusion.

The qualification

Generated tests still need execution and review.

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 password-reset regression candidates 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.

CHAPTER 50 / 60 Core + Pro

/carbon-map

Build or revisit a persistent product quality map with screenshot/widget inspection, paths and journeys, separate functional/business risks, adjustable weighting and ranked testing/regression-automation backlogs. Retain build changes and human steering; show explicit AI/human time and cost estimates for all test items.

Jay · Your AI test managerTesting operations

When to use it

You need to see journeys, risk and gaps spatially.

Before you start

Core shows the saved assessment map. Pro adds richer cross-build planning and retained priorities. Link map nodes to screenshots and evidence; unmapped areas are not covered by implication.

Try this in your coding agent.

Illustrated outcome

Jay asks about the costliest failure before committing to a plan.

Evidence to inspect

Question: wrong charge, blocked purchase or delayed receipt? Record the answer as context.

Still untested / not established

The demo does not submit or store a real answer.

Ready. Read the full example or play its steps.

What a useful result contains

A bounded claim

For human testing priorities, state the target, revision, environment and actual work performed. Keep planned, executed, blocked and untested work separate.

An inspectable trail

Question: wrong charge, blocked purchase or delayed receipt? Record the answer as context. In a real run, retain the source, trace, screenshot or fixture behind the conclusion.

The qualification

The demo does not submit or store a real answer.

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 human testing priorities 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-human result. Separate observed evidence, assumptions and untested scope, then recommend the next useful check.

When to use it

You want to compare deeper capabilities and support.

Before you start

This opens the marketing comparison only. It does not start checkout, purchase, install an edition or expose customer downloads. Model access and host charges remain separate.

Try this in your coding agent.

/carbon-pro Show the Pro features and pricing so I can compare upgrade options.

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