**Dataset Summary**

SWE-Skills-Bench is a benchmark dataset for evaluating whether injected skill documents — structured packages of procedural knowledge — measurably improve LLM agent performance on real-world software engineering tasks.

The dataset contains 49 skills spanning 565 task instances across six software engineering domains (Deployment & DevOps, Analytics & Monitoring, API Development, Data Science & ML, Security & Testing, and Developer Tools). Each skill is grounded in an authentic GitHub repository at a fixed commit, paired with a curated skill document and a deterministic pytest test suite that encodes the task's acceptance criteria.

The dataset is designed to answer: *Does giving an agent a skill document actually help?* The primary evaluation metric is pytest pass rate, measured under two conditions — with and without skill injection — to compute a pass-rate delta (ΔP) per skill.

The dataset was released as part of [SWE-Skills-Bench: Do Agent Skills Actually Help in Real-World Software Engineering?](https://arxiv.org/abs/2603.15401)

**Dataset Structure**

An example of a SWE-Skills-Bench datum is as follows:

```
skill_id:        (str) - Unique skill identifier, e.g. "fix", "tdd-workflow".
name:            (str) - Human-readable task name.
description:     (str) - One-line description of the task.
type:            (str) - Task category, e.g. "repair", "feature", "fix".
task_prompt:     (str) - Full task prompt passed to the agent (Markdown).
skill_document:  (str) - Curated skill document injected as agent context (Markdown).
test_code:       (str) - Pytest test suite used to evaluate the agent's output.
repo_url:        (str) - Target GitHub repository URL.
repo_commit:     (str) - Fixed commit hash for reproducibility.
docker_image:    (str) - Pre-configured Docker image for the evaluation environment.
```

**Supported Tasks**

SWE-Skills-Bench proposes a paired evaluation task: given a task prompt (with or without an injected skill document), an agent must complete a software engineering task on a real codebase. Correctness is verified by running the associated pytest test suite inside a Docker container.
