AgentsProof

AgentsProof is an SDK and hosted service that instruments AI agents to capture execution traces, grade runs against user-defined graders and approved test cases (Goldens), and generate public or private shareable proof reports. It targets builders and teams who need deterministic, explainable verification of agent behavior by combining deterministic trace assertions, LLM-based graders, and automatically generated synthetic variants of test cases. Integrations are designed to work with any LLM framework and the product provides a minimal Node/edge SDK to start capturing traces and producing report URLs in minutes.

Drop AgentsProof into your agent in 30 seconds. Get a public URL that proves it works — scored on goal completion, tool accuracy, efficiency, quality, and safety.

Key Features

SDK & Instrumentation (run.trace)

Lightweight Node/edge SDK with run.trace to wrap LLM and tool calls and capture a structured trace of each agent run.

Custom Graders

Define what 'good' means in plain English; every run is automatically graded against these rules and graders can be pinned to Goldens.

Goldens (Executable Test Specs)

Turn a passing run into an executable test spec with success criteria, expected behavior, and trace assertions; can be run on demand or batched in suites.

Trace Assertions

Structured, deterministic checks (for example: must_not_call, max_steps) that cause immediate failures if the agent violates them.

Synthetic Variants

AI-generated edge-case variants from approved Goldens to expand test coverage without writing tests by hand.

Proof Suites & Reports

Run approved Goldens in a suite with a single SDK call and generate shareable proof reports showing per-criterion pass/fail and multi-axis scores.

Public & Private Shareable Reports

Generates a publicUrl for each run/report to share results and proof that an agent met its success criteria.

Works with Any LLM Framework

Designed to integrate with a variety of LLM providers and tool frameworks.

Pricing

Free Tier Available

Free plan with 1 project, 200 eval runs/month, default LLM grader, 10 Golden test cases, 1 proof suite, public reports, and basic email support.

Use Cases

Regression detection after prompt or code changes

When prompts or code change and behavior breaks, AgentsProof catches regressions by grading real runs and failing Goldens or trace assertions.

Continuous verification and CI for agents

Run proof suites (batch of Goldens) to continuously validate agent behavior before shipping or after updates.

Shareable evidence of agent correctness

Create public or private proof reports to demonstrate to stakeholders that an agent meets specified success criteria.

Expand test coverage with synthetic edge cases

Automatically generate variants from approved Goldens to discover edge-case failures without hand-writing additional tests.
