Agent QA

Verify AI Agent Work Before Accepting It

Check an AI agent's final answer against the original task, claimed evidence, acceptance tests, stop rules, deployment proof, and remaining risk.

Best for: builders, founders, operators, and teams who use AI agents or coding agents and need a practical completion check before trusting the result.

Fast route that actually finishes the job

Start with Agent Output Evaluator. The supporting tools are included only when they make the output more trustworthy: conversion, cleanup, compression, preview, or verification. The goal is a checked artifact, not a long tour through a tool directory.

Agent Output EvaluatorPrimary starting point for this intent. Use it first and check the baseline output before adding steps. Agent Task Contract StudioUse only if this step verifies, converts, prepares, or reduces the final artifact. Proof Pack BuilderUse only if this step verifies, converts, prepares, or reduces the final artifact. Output Contract StudioUse only if this step verifies, converts, prepares, or reduces the final artifact. Live Quality LabUse only if this step verifies, converts, prepares, or reduces the final artifact.

Safe sample and expected output

Safe sample input

Task: fix PageSpeed. Final answer: all fixed. Evidence: mobile 98, desktop 100, deployed URL, remaining Cloudflare warning. Acceptance tests: mobile performance above 95, accessibility 100, routes 200.

Expected output

A pass, review, or fail verdict with missing evidence, unsupported claims, acceptance-test status, stop-rule risks, residual platform warnings, and a remediation prompt.

SMART RUN SHEET

Plan the run before touching the final file

This is the pre-flight layer most utility sites skip. Tell FastTool what you are trying to finish, how sensitive the input is, and what device you are using. The page returns a local readiness score, risk warning, first tool, and proof plan before you risk the real file.

Proof checks before you trust it

            
Use this checklist before you send, upload, publish, or reuse the output. If you cannot verify the result, do not treat it as finished.

            
  1. Map every acceptance test to pass, fail, or unknown.
    2. 

  2. Require a URL, file, report, screenshot, status code, or command result for every strong claim.
    3. 

  3. Separate third-party platform warnings from app defects.
    4. 

  4. Check whether the final answer overclaims completion or hides residual risk.
    5. 

  5. Create a smaller rerun prompt for anything missing or unsupported.

          

          

            
PROOF PASSPORT

            
Create a local verification receipt

            
This is the part most tool sites skip. Check the output, record the file or result you created, and copy a proof receipt for your notes, ticket, client handoff, or repeat workflow. Nothing is uploaded; this runs in your browser.

Common mistakes this route avoids

            
  • Accepting a confident final answer without evidence.
    • 

  • Treating local success as live deployment proof.
    • 

  • Ignoring stop rules because the answer sounds polished.
    • 

  • Mixing remaining Cloudflare, Google, or browser platform warnings with app bugs.
    • 

  • Forgetting to test the exact public URL users will open.

When not to use this workflow

            
Not for legal audit certification, regulated compliance sign-off, security approval, medical or financial decisions, or verifying private systems without pasted proof.

            
Privacy boundary

            
Paste only the task, claims, public URLs, redacted logs, and non-sensitive test evidence. Do not paste secrets, credentials, private customer records, or unreleased business data.

          

          

            
Why this is built for repeat visits

            
A returning visitor should not have to remember which of hundreds of utilities solves the job. This page keeps the exact intent, starting tool, supporting checks, sample, expected output, and stop condition on one stable URL.

            
The useful end state is simple: open the right tool first, protect private inputs, verify the artifact, and stop once the output passes the visible proof checks.
