Agent Evaluation & Benchmarking

Evaluation environments that reveal where agents actually fail.

We design realistic tasks, adversarial scenarios, and benchmark environments for teams measuring autonomous agent capabilities.

Strong benchmarks need more than hard prompts.

Agent evaluations need realistic environments, clear success criteria, shortcut resistance, robust rubrics, and failure analysis. Otherwise agents pass for the wrong reasons or fail in ways the benchmark cannot diagnose.

Tasks with unintended shortcuts

Rubrics that miss important failure modes

Environments that are too brittle or too easy

Agents passing through shallow pattern matching

Unclear distinction between model failure and task failure

Poor coverage of multi-step planning, tool use, and recovery

Services

Realistic worlds, stronger rubrics, better failure coverage.

Evaluation environment design

Build realistic worlds and workflows for testing autonomous agents.

Adversarial task construction

Design tasks that expose weaknesses in planning, tool use, reasoning, recovery, and robustness.

Benchmark hardening

Remove shortcuts, clarify rubrics, and improve task reliability.

Failure-mode analysis

Analyse where agents fail and turn those failures into better eval coverage.

Capability assessment

Create structured test suites for specific agent capabilities and domains.

Regression suites

Build repeatable eval packs to compare agents, prompts, tools, and model versions.

Relevant systems

For teams building and measuring autonomous agents.

This work is especially relevant for teams building coding agents, data agents, browser agents, terminal agents, workflow agents, and research agents.
