The Report

Eight artifacts. Not one chat reply.

Every diagnosis produces a structured, decision-ready report. Each artifact is designed to be acted on — not read and forgotten.

01

Executive Verdict

2-3 sentence diagnosis: severity, primary risk, and top issues.
Severity: High
Primary issue: Missing operating context
Required evidence: Not provided
02

Findings Table

Ranked root causes with evidence, severity, and fix difficulty.
1. Missing role context — High
2. No output structure — High
3. No grounding examples — Medium
03

Corrected Artifact

The fixed prompt, workflow, or agent — ready to paste.
+ Added role context
+ Added output schema
+ Added grounding examples
04

Risk Register

What could still go wrong after the fix — and how to watch for it.
Edge-case behavior: Not yet validated
Token limits: Operator must verify
Failure mode: Requires monitoring
05

Ownership Map

Who owns each fix — prompt engineer, ops, or engineering.
Role context → Operator to assign
Schema → Engineering to define
Monitoring → Ops to configure
06

Implementation Roadmap

Sequenced fix plan with dependencies and operator-supplied effort estimates.
Phase 1: Immediate containment
Phase 2: Structural repair
Phase 3: Validation and release
07

KPI Framework

How to measure whether the fix actually worked.
Success metric: Operator-defined
Baseline: Not provided
Target: Must be approved before release
08

Release Confidence Note

Go/no-go recommendation with confidence score and conditions.
Status: Ready for controlled testing
Condition: Operator must approve
Next step: Validate in staging

Diagnostic Levels

Four levels of diagnosis. From prompt to platform.

Start with a single prompt. Scale up to your entire AI operating system. Each level produces its own report package.

Level 01

PromptFlow

Diagnose and repair individual prompts. Find ambiguity, missing context, and output failures. Get the corrected prompt, not just feedback.
Prompt diagnosis Corrected artifact Version history Saved library 

          Output: 8-artifact prompt report

          Scope: Single prompt

          Best for: Individual prompt work
Level 02

Workflow Doctor

Diagnose multi-step AI workflows. Find bottlenecks, broken handoffs, and missing validation gates between steps.
Step-by-step audit Failure actions Timeout analysis Idempotency checks — prevents duplicate runs 

          Output: Workflow diagnostic report

          Scope: Single workflow / SOP

          Best for: Teams running production AI
Level 03

Agentic Workflow Doctor

Diagnose autonomous agent systems. Find loop failures, tool governance gaps, memory scope errors, and missing human checkpoints.
Agent role audit — checks each agent's responsibilities Tool governance — controls what an agent is allowed to do Loop guards — prevents runaway agent loops Human escalation — defines when a human must step in 

          Output: Agentic diagnostic report

          Scope: Multi-agent system

          Best for: Teams deploying autonomous agents
Level 04

Workflow OS Doctor

Diagnose your entire AI operating system. Cross-workflow dependencies, data contracts, blast radius, and cascading failure modes.
OS layer blueprint — maps your entire AI infrastructure Data contracts — defines what passes between workflows Blast radius — shows how one failure spreads Governance audit 

          Output: Platform OS diagnostic

          Scope: Full AI operating system

          Best for: Teams managing multiple workflows
Before & After

What a diagnosis actually fixes.

An illustrative test case. This example shows how missing context, output structure, and evidence requirements can create inconsistent results — and how a diagnosis corrects them.

Before — Under-specified 
You are a helpful assistant. Write a sales email to our customers about our new product. Make it good.
Issues found:
• No role context — increases the risk of unsupported assumptions
• No output format — creates inconsistent length and structure
• No examples — quality criteria are undefined
• No guardrails — tone may shift across recipients

Result: Inconsistent output across different inputs and contexts.
After — Structured 
You are a B2B SaaS copywriter.
Product: [PRODUCT_NAME]
Audience: [SEGMENT]

Write a 120-word sales email.
Tone: professional, warm.
Include: subject line, CTA.

Examples:
[Example 1: existing customer win]
[Example 2: onboarding email]
Fixes applied:
• Added role context (B2B SaaS copywriter)
• Added output schema (120 words, specific sections)
• Added 2 examples for grounding
• Added guardrails (tone, CTA, subject line)

Result: Structured, testable, and ready for controlled testing.
How It Works

Submit. Diagnose. Challenge. Verify. Deliver.

A multi-model diagnostic process analyzes, challenges, and verifies the result before delivery.

Submit

Paste your prompt, workflow, or agent instructions.

Diagnose

The engine analyzes the submission and produces initial findings.

Challenge

The engine challenges findings and flags unsupported claims.

Verify

The engine verifies the result against the required output contract.

Deliver

Receive the full 8-artifact report. Most diagnoses complete in under 10 minutes.
TryPromptFlow caught a context-loss issue in our agent loop that we had missed. The corrected version gave us a clear path to test the fix.

Questions

Frequently asked.

Everything you need to know before running your first diagnosis.

What exactly does TryPromptFlow do?
TryPromptFlow uses a multi-model diagnostic process that analyzes, challenges, and verifies your submission. The findings are combined into one structured report with 8 decision-ready artifacts — Executive Verdict, Findings Table, Corrected Artifact, Risk Register, Ownership Map, Implementation Roadmap, KPI Framework, and Release Confidence Note.
How long does a diagnosis take?
Most diagnoses complete in under 10 minutes and produce a complete 8-artifact diagnostic package. Longer submissions or complex workflow/agent diagnostics may take additional time.
Is there really a free trial?
Yes. One full diagnosis free. No credit card. After the report, choose a plan or stop.
How is my data handled?
Your submission is used only to perform the requested diagnosis. We do not use customer content to train shared models. Diagnostic metadata may be retained for security, billing, reliability, and account functionality in accordance with our data policy.
What types of AI work can I diagnose?
Single prompts, multi-step workflows, autonomous agent systems, and full AI operating systems. Each diagnostic level produces its own report package tailored to the scope of what you submitted.

Why the Same Prompt Stops Working on Monday

A prompt can work on Friday and fail on Monday without anyone changing the words. The problem is usually upstream.

Consultants

Why Clients Can't Follow Your SOPs

SOP failures often trace to a small set of recurring specification problems. The issue is often a specification gap rather than an implementation failure.

Agencies

Your Team Uses the Same AI Tool. Different Results.

When the same prompt produces inconsistent output across team members, the issue is often a specification gap rather than an individual skill gap.
