The only reliable way to compare coding agents is to make them solve representative work from your own repositories under the same conditions, then grade the resulting patches against acceptance criteria and regression tests. Treat public benchmark scores as context—not a substitute for a controlled, team-specific evaluation.
What a meaningful coding-agent evaluation measures
A coding agent is more than a language model. Its result depends on the model version, agent loop, system instructions, tools, repository context, permissions, retry policy, time limit, and compute environment. A benchmark score therefore describes a configured agent system, not a model in isolation. Anthropic’s evaluation guidance makes the same distinction when discussing software-engineering agents: the harness and resources are part of what is being tested.

Your evaluation should answer six separate questions:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Can the agent implement the requested behavior?
- Does the change preserve existing behavior?
- Is the patch maintainable, secure, and consistent with local conventions?
- Does it work reliably rather than only on an occasional run?
- What time, service usage, and human intervention does it require?
- Does it fit the permissions, tools, review process, and repositories your team actually uses?
Do not collapse these dimensions into one unexplained number. A fast agent that needs extensive repair may be less useful than a slower agent that produces reviewable patches.

Build a representative private task set
Start with work your team recognizes, not a collection chosen because it is easy to grade. Preserve each task’s original context, issue description, constraints, and acceptance criteria. Remove confidential data only when necessary, and record any redaction that could change the task’s difficulty.
Balance the types of work
A practical suite includes several categories:
- Bug fixes: reproduce a defect, identify the cause, and correct it without changing unrelated behavior.
- Small features: add a user-visible or API-visible capability with explicit requirements.
- Refactors: change structure while preserving specified behavior, interfaces, and performance expectations.
- Tests: add missing unit, integration, or regression coverage for a stated failure mode.
- Maintenance: update configuration, dependencies, migrations, documentation, or build tooling where those activities are part of normal work.
Include the languages, frameworks, repository sizes, build systems, and service boundaries that matter to your team. Mix straightforward tasks with ambiguous ones that require reading existing code and clarifying assumptions. If every task has a neat unit-test answer, you are measuring test completion more than engineering judgment.
Choose tasks without leaking the answer
Give every candidate the same starting commit and the same task information. Do not include a reference patch, hidden hints, or files that reveal the expected implementation. Avoid selecting only issues that resemble a public benchmark; repeated exposure can measure memorization rather than problem-solving.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsThere is no source-supported universal task count. A small team can begin with a pilot that covers each work category and repository family, then expand until the confidence interval around its conclusions is useful. Keep a holdout set that no agent sees during prompt or tool tuning.
Freeze the unit of comparison
Decide whether you are comparing complete products or attempting to isolate a model. For a buying or workflow decision, compare the complete configuration the team would deploy. If you intend a model comparison, keep the surrounding scaffold identical and label the result accordingly.
| Control | What to record | Why it matters |
|---|---|---|
| Agent and model | Exact product, model, release or build identifier, and date | Behavior can change between versions. |
| Instructions | System prompt, task prompt, repository rules, and any templates | Prompt differences can dominate outcomes. |
| Tools and permissions | Shell, editor, search, browser, network, package installation, secret access, and write scope | An agent with broader access has a different task. |
| Repository context | Commit hash, checked-out files, generated artifacts, environment variables, and documentation available | Different context creates incomparable starting conditions. |
| Execution policy | Maximum wall-clock time, retry limit, sampling or temperature settings, and stop rules | More attempts can raise completion while increasing cost. |
| Resources | CPU, memory, storage, parallelism, container image, dependency cache, and service quotas | Resource pressure can look like model failure. |
When a candidate cannot use the same tool or permission set, do not quietly call the results a model comparison. Report that you compared two whole workflows and explain the difference.
Define success before anyone runs a task
Write observable acceptance criteria for each issue. A criterion should state what a user, API client, operator, or maintainer can verify. “Improve the parser” is not gradeable; “reject an unterminated quoted field with the documented error and leave the stream reusable” is.

Use layered grading
- Task-specific checks: tests or scripts that exercise the requested behavior, including edge cases named in the issue.
- Regression checks: the existing test suite and any tests covering adjacent behavior.
- Static and policy checks: formatting, type checking, linting, dependency policy, security scanning, migration validation, or license rules that your team normally requires.
- Human review: a documented rubric for maintainability, clarity, architecture, security, observability, and operational risk where automation cannot decide.
Anthropic describes deterministic grading as a natural fit for coding because software can generally be run and tested: “does the code run and do the tests pass?” See the full statement in the January 9, 2026 guidance. Deterministic tests are powerful, but they grade the behavior encoded in those tests. A missing assertion can produce a false pass.
Separate correctness from patch quality
A patch that passes visible tests is not automatically acceptable. Have reviewers answer predeclared questions such as:
- Does the implementation follow the repository’s established abstractions?
- Does it handle errors, concurrency, retries, and input validation appropriately?
- Does it introduce unnecessary dependencies, duplicated logic, or fragile test-specific behavior?
- Are security-sensitive operations authorized, logged, and bounded?
- Will another engineer understand how to modify it later?
Use at least two reviewers for a sample of tasks, and blind them to the agent identity when practical. Record disagreements rather than forcing a single subjective score.
Run the evaluation as a controlled experiment
Prepare an isolated environment for each run. The candidate should receive the same repository snapshot, task wording, tools, credentials policy, and time budget. If network access or external services are required, provide the same fixtures or controlled endpoints.
- Register the task: assign an ID, repository commit, category, difficulty notes, acceptance criteria, and test commands.
- Provision the environment: build the pinned container or virtual machine, install dependencies, and verify that the baseline tests pass before the agent starts.
- Start from a clean checkout: remove edits, generated files, caches that are not intentionally shared, and prior agent traces.
- Launch with the frozen configuration: save the exact prompt, instructions, model identifier, tool permissions, retry policy, and start time.
- Allow normal operation: do not coach one candidate unless coaching is part of the workflow being evaluated. If a human must intervene, record the intervention and its reason.
- Run grading automatically: apply task-specific tests, regression tests, and policy checks in a defined order. Save complete output and exit status.
- Review the patch: use the same rubric and reviewer process for every candidate. Note defects even when automated checks pass.
- Classify the outcome: distinguish a correct completion, partial completion, agent failure, and infrastructure or dependency failure.
- Reset before the next run: restore the exact baseline so one candidate cannot benefit from another’s changes or caches.
Record the full trajectory and infrastructure conditions
Save the task prompt, tool calls, command output, file changes, test results, elapsed time, token or service consumption where available, and resource utilization. A final diff alone cannot tell you whether the agent solved the problem efficiently, retried blindly, or received extensive human help.
Classify failures explicitly:
- Task-solving failure: the agent misunderstands the requirement, writes incorrect code, stops early, or cannot recover from an error.
- Environment failure: a broken dependency mirror, unavailable service, corrupted cache, container crash, timeout, quota, or permission problem prevents a fair attempt.
- Grader failure: a test, fixture, or harness defect produces an invalid result.
Anthropic’s analysis of coding-evaluation infrastructure shows why this separation matters: resource configuration and infrastructure errors can affect scores independently of model capability. Document the conditions and read its infrastructure-noise analysis. Define in advance whether an infrastructure failure is retried, excluded, or counted against workflow reliability. Apply that rule to every candidate.

| Axis | Suggested measurement | Interpretation |
|---|---|---|
| Task success | Share of tasks meeting every mandatory acceptance criterion | Primary measure of requested behavior. |
| Regression safety | Existing and task-relevant tests passed; severity of new failures | Shows whether the patch breaks surrounding functionality. |
| Patch quality | Rubric score plus reviewer defect count and severity | Captures maintainability and risks tests miss. |
| Reliability | Success consistency across repeated runs, with infrastructure failures reported separately | Distinguishes dependable behavior from lucky completions. |
| Speed | Wall-clock time to a graded patch, reported with the time limit | Useful for queue planning and interactive workflows. |
| Consumption | Tokens, service calls, compute time, or other metered usage under one stated accounting method | Enables a defensible cost estimate. |
| Human intervention | Number, duration, and type of prompts, edits, approvals, or restarts | Shows how much engineering labor remains. |
| Workflow fit | Qualitative review of tools, permissions, repository context, review integration, and operational controls | Determines whether the system can be adopted safely. |
Choose any weighting with your stakeholders, but publish the weights and keep the underlying measurements visible. A team that values production safety may weight regression severity and security review more heavily than speed; another may prioritize latency for an interactive coding loop. The weights are a decision policy, not an objective property of an agent.

SWE-bench Verified
SWE-bench Verified is a human-validated subset of 500 software-engineering instances drawn from real repositories. Its task format—issue resolution evaluated by tests—can help you understand one kind of coding-agent capability. It does not establish how an agent will perform on your languages, architecture, internal tooling, requirements, or review standards.
There is also a current qualification that should change how the number is used. In “Why we no longer evaluate SWE-bench Verified,” published February 23, 2026, OpenAI says design and contamination concerns mean improvements on this benchmark no longer provide a meaningful measure of real-world software-development progress. Do not use a high score as a guarantee, trend line, or procurement ranking.
The earlier announcement, “Introducing SWE-bench Verified” from August 13, 2024, explains the human-validation context. Treat the 500-instance figure as dataset scope, not current agent performance.
SWE-Lancer and broader task formats
OpenAI’s Evals catalog describes SWE-Lancer as more than 1,400 freelance software-engineering tasks from Upwork, with a stated total task value of $1 million USD. That expands the represented work beyond a single issue-resolution format, but it still cannot reproduce your private codebase, requirements, credentials, release process, or definition of acceptable maintenance. Use it to broaden your questions, then test those questions locally.
Analyze the results and make a deployment decision
Look at the distribution, not only the mean
Break results down by task category, repository, language, ambiguity, and difficulty. One overall completion percentage can conceal a serious weakness—for example, strong test additions but poor migration work, or good bug fixes with unacceptable security findings. Report the number of tasks in each subgroup so a small category cannot dominate the conclusion.
Inspect failures qualitatively
For every failed or partially successful task, identify the earliest meaningful failure: misunderstood requirement, ineffective search, incorrect plan, tool error, test misdiagnosis, unsafe change, or inability to recover. This reveals whether prompt changes, better repository documentation, permission changes, or a different agent loop could address the problem.

Set adoption gates
Before seeing results, define minimum conditions such as:
- No critical security or data-loss defects in the reviewed sample.
- Mandatory acceptance criteria met on a stated proportion of tasks.
- No unacceptable regression pattern in a protected test area.
- Human intervention below a limit your team can staff.
- Infrastructure failure rate low enough for the intended workflow, with a documented recovery path.
These are governance choices, not universal industry thresholds. If an agent fails a gate, limit it to a narrower task class rather than averaging the failure away.
Common evaluation mistakes and fixes
Changing the harness between candidates
Symptom: one agent receives more context, retries, memory, or network access. Fix: freeze the configuration table and report unavoidable differences as a whole-workflow comparison.
Grading only whether code compiles
Symptom: plausible patches pass a build but violate the issue, break edge cases, or degrade security. Fix: add explicit acceptance tests, regression tests, and a human rubric.
Counting infrastructure errors as model failures
Symptom: timeouts, missing packages, or exhausted quotas lower one candidate’s score. Fix: classify the incident, retain logs, and apply a predeclared rerun or exclusion rule.
Allowing silent human rescue
Symptom: an evaluator edits files or supplies unstated hints, but the final result is recorded as autonomous. Fix: log every intervention and report autonomous and assisted outcomes separately.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Tuning prompts on the test set
Symptom: repeated runs improve the visible suite while holdout performance remains unknown. Fix: maintain a private holdout set and freeze it before optimization.
Turning a benchmark into a product ranking
Symptom: a public score is treated as proof that one named agent is best for every team. Fix: use benchmark methodology to design questions, then run the same private tasks and accounting for every candidate.
A repeatable evaluation record
For each task-run pair, retain a record with:
- Task ID, repository and commit hash.
- Acceptance criteria and grading commands.
- Agent, model, prompt, tools, permissions, and resource configuration.
- Start and end timestamps, retries, interruptions, and human interventions.
- Patch, complete tool trace, test output, static-check output, and reviewer rubric.
- Resource or service consumption and any infrastructure incident.
- Final classification and the reason for failure or acceptance.
Version this record format with the evaluation suite. When the repository, model, tools, or grader changes, mark the run as a new evaluation rather than silently merging it with older results.
Frequently asked questions
Should I evaluate an agent on synthetic tasks?
Synthetic tasks can isolate a capability, such as API use or code search, but they are weak evidence for adoption by themselves. Use them as diagnostic probes alongside representative tasks from your repositories.
How should I compare an agent that edits interactively with one that submits a complete patch?
Define the workflow boundary first. If your team wants autonomous pull requests, measure an end-to-end patch under a fixed intervention policy. If the intended use is pair programming, measure the same interaction time, permissions, and human prompts for every candidate. Do not compare an assisted result with an autonomous result without labeling the distinction.
What if my existing tests are incomplete?
Add task-specific tests before the evaluation and mark uncovered requirements for human review. Treat the missing coverage as a property of the grading system, not evidence that a passing patch is fully correct.
When should I rerun a task?
Rerun according to a rule written before execution—for example, after a documented infrastructure failure, not after an ordinary reasoning failure. Preserve the original result and report both the incident and the rerun outcome.
Frequently Asked Questions
Can a public benchmark replace testing on our own codebase?
No. Public benchmarks provide a useful task format and an external reference, but they cannot reproduce your repository, requirements, permissions, tests, or review standards.
Free tools Windows power users keep installed
One-click scans. No signup required.
What is the most important metric for a first pilot?
Use mandatory task completion together with regression safety, then inspect patch quality and human intervention. A single completion percentage is insufficient.
Should infrastructure failures be included in an agent’s score?
Report them separately from task-solving failures, while also measuring workflow reliability. Apply the same predeclared retry or exclusion rule to every candidate.
