Benchmark worksheet

Scope an agent tool benchmark before you spend.

A practical template for turning a vague tool comparison into a decision, task set, metrics, evidence plan, and budget that an agent operator or buyer can trust.

Updated 2026-05-19For benchmark pilotsMarkdown worksheet included
Use this when: a team is about to compare search APIs, MCP servers, browser automation tools, document extraction products, CLIs, or internal platforms that agents will call. The template is designed to stop under-scoped pilots becoming misleading public leaderboards.

What the template forces you to decide

Decision

Who needs the result, what choice it will support, and what happens if the answer is inconclusive.

Category boundaries

Which tools are genuinely comparable, which tools are excluded, and which caveats matter before ranking anything.

Agent workflow

The real trigger, tool calls, expected output, verification step, and recovery path the benchmark should represent.

Evidence

The request, response, URLs, timestamps, receipts, logs, and review notes that make the result auditable later.

Recommended pilot shape

PartDefault starting pointWhy it matters
Task set10–20 tasks across easy, ambiguous, current-fact, error-prone, and multi-step cases.Small enough to debug; varied enough to reveal bad task design and provider mismatch.
Providers2–4 tools that solve the same job, not adjacent categories mixed together.A SERP wrapper, answer API, extraction API, and research agent should not share one raw score.
RunsAt least one clean run plus reruns for adapter bugs and timeouts.Most benchmark waste appears in reruns, not the first happy-path request.
MetricsOne primary metric, a few secondary metrics, latency, errors, and cost per successful task.Prevents a single opaque score from hiding the reason a tool is or is not fit for agents.

Worksheet excerpt

Decision: - What decision should the benchmark support? - Who will use the result? - What happens if the answer is inconclusive? Agent workflow: - Trigger or user request: - Tool calls required: - Expected output: - Verification step: - Failure recovery path: Evidence to preserve: - Prompt/task, request, raw response or redacted excerpt - URLs / IDs / receipts, timestamps, agent logs, judging notes

How it connects to budget

The worksheet pairs with the benchmark cost guide. Once the task count, provider count, judging plan, and evidence plan are explicit, the budget becomes a set of assumptions instead of a guess.

Send the tool category, the decision you need to make, and any providers already on the shortlist. AgentFirstTools can help turn that into a pilot plan, evidence checklist, or paid audit scope.
