Reading agent case studies critically

A case study is evidence about a particular system under particular conditions. Learn to separate transferable ideas from headline claims.

Ask what was actually measured

Research systems such as SWE-agent study how an agent interacts with a software environment to solve repository tasks. The useful lesson is not that a reported score applies to your support product. It is that the interface, tools, task selection, and evaluation setup shape observed performance.

How it works

When reading a paper or product story, record the dataset, system configuration, baseline, sample size, allowed resources, success definition, and failure analysis. Check whether the comparison changes more than one factor. Distinguish a measured result from an author's hypothesis about why it happened.

A concrete example

A new tool interface might improve completion on a fixed repository benchmark. To transfer the idea, form a support-specific hypothesis: a narrow policy lookup interface will reduce invalid calls. Compare it with the old interface on the same support cases, tracking both invalid requests and final answer quality.

Apply it to your assistant

Add a missing experimental detail and decide whether the claim is reproducible. Before running the exercise, predict the result. Afterward, explain which assumption changed and add one case where the system should refuse, ask for clarification, or escalate.

All exercise inputs and outputs are deterministic teaching examples. No language model is called. Run the same idea against a versioned dataset before making a production claim.

Key takeaway

Transfer hypotheses and methods from case studies, then test them in your own setting.

JavaScript exercise: Reading agent case studies critically · code experiment

Add a missing experimental detail and decide whether the claim is reproducible.

const report = { dataset: 'support-v1', sampleSize: 100, promptVersion: 'p3', modelVersion: null, scoringRule: 'rubric-v2' };
const missing = Object.entries(report).filter(([, value]) => value === null).map(([key]) => key);
console.log({ reproducibleSetup: missing.length === 0, missing });

Knowledge check

A coding agent succeeds on a repository benchmark. What can you conclude about support-agent accuracy?

1. It must achieve the same score
2. Nothing quantitative without a relevant evaluation
3. It needs no tool validation
