1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsTo compare AI coding agents fairly, give each one the same app specification, starting repository, tools, runtime, and time or usage budget. Then grade the results against independent behavior checks and a published rubric, repeat runs where possible, and report reliability, time, and cost alongside success. The result describes those agent configurations in that test environment—not a permanent ranking of coding tools.
Decide what your comparison is meant to measure
There are two useful kinds of comparison, but they answer different questions. State which one you are running before you choose the agents.
| Comparison | What to hold constant | What the result can tell you |
|---|---|---|
| Agent comparison | Use the same model and model version where possible; also align reasoning settings, tools, context, and budget. | How the agent’s scaffolding and workflow perform under the chosen conditions. |
| Whole-product comparison | Use each product’s ordinary model, tools, and defaults, while giving each the same task and equivalent resources where possible. | How the products perform as users encounter them. The result combines model and agent effects. |
Do not present a whole-product result as evidence that one underlying model is better. If you cannot align an important condition—for example, a product requires a different environment—record the difference and treat it as part of the tested configuration.
Specify one app task that can be judged
Write a narrow, reproducible task rather than asking an agent to “make a great app.” An open-ended brief invites different interpretations and makes a score difficult to explain. Your specification should identify:

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- The app’s purpose, required screens, and primary user flows.
- Required data behavior, including persistence or error handling when those are part of the task.
- Explicit acceptance criteria: observable outcomes that determine whether each requirement is met.
- The starter repository or exact baseline files, framework and version, dependency setup, operating system or container, and required run command.
- Whether the agent may ask clarifying questions. If it may, prepare the same answers for every agent; if it may not, say so in the task.
For example, a notes-app task could require creating a note, editing it, and seeing the edit after a restart. Those are observable criteria; “make the notes experience intuitive” is not, unless you also define how usability will be assessed. Keep the exact prompt and initial repository state so another person can reproduce the run.
Decide how clarification works
Questions can be part of app-building rather than a distraction from it. Decide whether agents get a fixed set of answers, can inspect the repository for answers, or must proceed without clarification. Give equivalent agents equivalent information, and retain the questions and answers with the run record. Research on interactive project-building evaluation treats clarification as part of the task and grounds simulated user answers in repository behavior; that is a useful design precedent, not a requirement that every evaluation use simulated users.
Make execution conditions equivalent
Use the same repository state, dependency versions, machine or container, permissions, network access, available tools, and CPU and memory allocation. Set the same time or token ceiling where possible. Record retries, manual interventions, and any deviation from the rules. If one product needs a different setup, disclose it rather than silently changing the test.

Anthropic’s engineering article Quantifying infrastructure noise in agentic coding evals puts the fairness issue plainly: “Two agents with different resource budgets and time limits aren’t taking the same test.” In its Terminal-Bench 2.0 experiment, Anthropic kept the Claude model, harness, and task set constant while varying resource configurations. Infrastructure errors were 5.8% under strict enforcement and 0.5% uncapped in the configurations tested. Those rates describe that experiment; they are not a general correction factor for other agents or environments.
Free tools Windows power users keep installed
One-click scans. No signup required.
Agentic coding evaluations often let agents install dependencies, run tests, and iterate. Those capabilities make the environment part of the task: a network block, missing system package, or short execution limit can change what the agent is able to do.
Test the app independently of the agent
Translate acceptance criteria into checks before running the agents. Use automated tests where they fit, then exercise the application as a user would: build and launch it, complete the main flows, and check persistence, error cases, or existing features when the task requires them. Keep behavioral results separate from subjective review. A visually polished app should not compensate for broken required behavior, and passing hidden tests should not erase a visible requirement that failed.

Audit the tests as well as the outputs
A test suite is evidence only if its prompts and checks faithfully represent the intended task. OpenAI’s 2026 audit of the public SWE-Bench Pro split reported that a human annotation campaign identified 249 of 731 tasks as broken (34.1%) and estimated roughly 30% were broken. Its automated pipeline separately flagged 200 tasks (27.4%). The audit grouped issues including overly strict tests, underspecified prompts, low-coverage tests, and misleading prompts. These are figures about that audit and public split—not a general estimate of defect rates in coding benchmarks.
Before treating a score as meaningful, check that the prompt is understandable, the tests cover the requirements, and the expected behavior is actually what the task intended. An agent can execute correctly and still receive an unreliable score if the evaluator is flawed.
Score more than whether it runs
Choose the dimensions and scoring rules before seeing the results. Use a rubric that matches the app and publish examples of what counts as a pass or a particular quality level. Keep the measures distinct so readers can see what an agent did well and where it fell short.

| Dimension | What to record |
|---|---|
| Required behavior | Acceptance criteria met and test results for each required flow. |
| Build and launch | Whether the app builds and starts in the specified environment, with failures recorded. |
| UI clarity and usability | Observations against stated criteria, rather than an unexplained overall impression. |
| Code structure and maintainability | Whether the implementation is organized and understandable under the rubric’s defined standards. |
| Security and data handling | Checks relevant to the task’s scope; do not imply a full security review if none was performed. |
| Error states and completeness | Whether expected errors and incomplete or empty states are handled as specified. |
| Human correction effort | Time and changes needed to bring the result to the stated acceptance criteria after the agent stops. |
| Efficiency | Elapsed time, usage, and cost under the recorded conditions. |
App-building frameworks offer useful examples of multidimensional assessment. SWE-WebDevBench separates creation from modification requests and examines product, engineering, and operations angles. ICAE-Bench reports functional correctness alongside semantic/API similarity, structural fidelity, design quality, and interaction quality. Treat these as methodological precedents; their metrics need not fit every app or team.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Repeat runs and preserve the spread
When resources allow, run each configuration more than once, especially when sampling or autonomous loops can produce different outcomes. Preserve each run rather than keeping only the best result. Report the run count, successes, failures, incomplete runs, timeouts, and infrastructure failures; do not silently discard inconvenient trials or label an infrastructure failure as an agent failure.
For each run, retain the configuration, prompt, repository revision, logs, generated artifacts, test outputs, interventions, elapsed time, and usage or cost. Report distributions for time and cost, not just the fastest or cheapest run. If you publish an aggregate, show how it was calculated and keep the per-run results available so readers can see variability.

The Artificial Analysis Coding Agent Index v1.5 methodology, current in September 2026, illustrates why configuration and efficiency details matter: it reports an equal-weight average across 303 tasks in three components—113 DeepSWE v1.1 tasks, 66 Terminal-Bench 4.0 tasks, and 124 SWE-Atlas-QnA tasks—and separates agent variants when behavior-changing settings differ. It also reports cost, token use, and execution time alongside benchmark scores. Its aggregate is specific to those components and methodology, not a substitute for reporting the details of your own app task.
State what the result cannot establish
One app task can show how the tested configurations handled that app, brief, and environment. It cannot establish which agent is universally best. Broader claims require varied task types and app domains, separate coverage of creation and later modification, and ideally held-out tasks that reduce the risk of benchmark familiarity.
Benchmark counts and grading methods need context too. SWE-bench describes Verified as a human-validated subset of 500 instances. SWE-bench Mobile documents 50 tasks and 449 human-verified test cases, but its described evaluation uses diff-based structural analysis: it inspects patch text without compiling or running the iOS application. A result from that grader therefore answers a different question from an end-to-end test of a built app.
Publish benchmark and harness versions with any comparison. SWE-bench’s official Verified documentation notes that setup versions can affect comparability; it describes controlled model comparisons using a shared mini-SWE-agent bash-only setup. A few percentage points should not be treated as decisive without checking the environment, resource enforcement, evaluator quality, and what the grader actually checks.
