AgentsProof

AgentsProof provides a lightweight SDK and service to instrument AI agents, capture their step-by-step traces, and automatically grade runs against user-defined success criteria and approved test cases (called Goldens). It is aimed at developers building and shipping agents who want deterministic, explainable evaluations and public shareable proof reports rather than informal "vibe checks." The product supports quick integration (one package, zero config) and produces per-criterion pass/fail details alongside multi-axis scores for each run.

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 for tracing

One-package SDK that wraps LLM and tool calls (run.trace) to capture per-step traces in Node or edge runtimes.

Custom Graders

Write rules in plain English to define what 'good' means; every run is automatically graded against these graders.

Goldens (executable test specs)

Turn a passing run into a Golden with success criteria, trace assertions, and expected behavior; Goldens can be executed against future runs.

Trace Assertions

Structured, deterministic checks (e.g., must_not_call, max_steps) that fail immediately when trace assertions are violated.

Synthetic Variants

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

Proof Suites

Run all approved Goldens (and their variants) in a single proof suite; results show per-criterion pass/fail for every case.

Shareable proof reports

Generates public (and with Pro, private) proof reports showing scores and per-criteria explanations for each run.

Pricing

Free Tier Available

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

Use Cases

Regression testing for agents

Run Goldens and proof suites to catch regressions when prompts, models, or agent logic change.

Safety and privacy enforcement

Enforce rules such as 'the agent must never reveal user PII' using graders and trace assertions.

Ship readiness and QA

Run proof suites as a pre-release check to ensure agents meet success criteria across cases and variants.

Shareable evidence for stakeholders

Publish proof reports to demonstrate to teammates or customers that an agent meets defined behaviors.

Benefits

Turns ephemeral agent runs into explainable, reproducible proof reports with per-criterion results.
Enables deterministic checks via trace assertions to catch issues automated grading might miss.
Generates synthetic variants to expand test coverage without hand-writing many test cases.
Minimal integration effort: one npm package and run.trace instrumentation.
Free tier available to start and a Pro plan for higher usage and private reports.

Getting Started

  1. 1 Step 1: Install the SDK (npm i agentsproof).
  2. 2 Step 2: Wrap each LLM and tool call with run.trace('event', ...) to capture trace data.
  3. 3 Step 3: Add custom graders (plain-English rules) in the dashboard to define success criteria.
  4. 4 Step 4: Save a passing run as a Golden (set success criteria and trace assertions).
  5. 5 Step 5: Run a proof suite (one SDK call) to execute approved Goldens and generate a report.
