# SWE-bench Style Coding Agent Dataset: GitHub Issues, Patches & Tests (Decontaminated)

*Release name: SWEGraph v3 — Free Toy Sample*

A free, deterministic, deliberately tiny toy sample of **SWEGraph v3**: **950 agent tasks from 25 repository
families**, with every row linked to them (50 of the tasks also appear as eval tasks). SWEGraph v3 is the
complete SWE-bench family, SWE-smith and BigCodeBench normalized into proof chains (`repo -> issue -> fix -> diff
hunks -> tests -> agent task -> eval task`), each task linked to its license, its container image and its execution
evidence, with identity/contamination groups and a leakage-audited split. The full package is sold separately (see
below).

## Free toy sample

This public repo is a deliberately tiny, CSV-only toy sample: 950 agent tasks plus the rows linked to them. It is meant for looking at the schema and running a pipeline once (a toy training run), not for training a real model. The full and training-ready versions (`williamTLmiller/swe-bench-coding-agent-tasks-full`) are private and licensed separately; contact energea@energeatech.com.

* **License:** CC BY-NC 4.0 for the MatrixNorm normalization/packaging layer (see
  [Licensing](#licensing)).
* **Format:** plain **CSV** in `csv/` plus `repo_licenses.csv` at the root (list fields pipe-delimited, dicts as
  JSON). Every data file in this repo is a plain CSV table.
* **Metadata only:** the text columns (`problem_statement`, `hints_text`, `requirements`, `interface`, `patch`,
  `test_patch`, `bug_patch`, `solution`, `title`, `input_summary`, the issue body and diff lines) are empty in
  this sample. Licenses, images, difficulty, tests, gate results and validity labels are all here. The full
  package carries the text for every permissively licensed task.

```python
from datasets import load_dataset
tasks = load_dataset("williamTLmiller/swe-bench-coding-agent-tasks", "agent_tasks", split="train")
```

## What is in this toy sample

| Source | `split` | Agent tasks |
|---|---|---:|
| SWE-bench train | `train` | 420 |
| SWE-smith | `train` | 380 |
| SWE-smith | `heldout` | 100 |
| SWE-bench Multimodal | `heldout` | 25 |
| SWE-bench Pro V2 | `heldout` | 25 |
| **Total** | | **950** |

* **Split:** 800 `train` and 150 `heldout` tasks (the full package's partition, unchanged). The
  50 SWE-bench Multimodal and Pro tasks are also in `eval_tasks.csv` as eval tasks, so
  `heldout_eval.csv` has 200 rows (100 SWE-smith tasks + 50 tasks x 2 views);
  `train.csv` holds the 800 `train` tasks.
* **Difficulty tier:** easy 330, medium 366, hard 162, very hard 92.
* **Code text status** (what the full package ships): included (permissive license) 922,
  withheld (copyleft) 25, withheld (license not detected)
  3.
* **Execution evidence:** 530 tasks carry what the source's authors executed
  (`upstream_reported`); 420 SWE-bench train tasks have a patch and tests only
  (`patch_only`). 530 tasks are linked to a published container image.
* **Languages:** Python 859, Go 57, JavaScript 34.
* **Tests:** 3,398 FAIL_TO_PASS and 216 PASS_TO_PASS test rows, the
  tests named by the sampled tasks.
* **Issue dates** (`created_at`, SWE-bench train issues): 2014-05-02 to 2023-08-21.

## Safe task setup

```bash
docker run -it --network none <environment_image> bash
cd /testbed                       # /app for SWE-bench Pro
git apply bug.diff                # SWE-smith only: bug_patch sets up the task's start state
rm -rf .git && git init -q && git add -A && git -c user.name=t -c user.email=t@t commit -qm task
```
Re-initialising git removes every ref, reflog entry and object an agent could read the
answer from (`git log --all`, other tasks' bug branches, upstream commits made after the
base commit). Do it for every task, from every source, before the agent starts.

## How the toy sample was drawn

* **Unit = agent task**, drawn from the 25 repository families of the earlier, larger free sample. Tasks are stratified by
  source and split (100 SWE-smith heldout, 25 SWE-bench Multimodal, 25 SWE-bench Pro,
  380 SWE-smith train, 420 SWE-bench
  train) and, inside each stratum, taken in a fixed salted-SHA-256 order of the instance id
  (`sha256("matrixnorm-toy-v1|" + instance_id)`), so the pick is deterministic.
* Tasks whose FAIL_TO_PASS or test-id list is longer than 32,767 characters (a spreadsheet cell's limit) are left
  out of the toy; they are in the full package.
* **Linked rows follow the tasks:** issues, pull requests, diff hunks, tests, eval tasks, execution proofs, task
  validity, quality, split memberships, environments and repositories keep the rows of the sampled tasks;
  `train.csv` / `heldout_eval.csv` are cut to them. `split_manifests` (28 rows) is included in full, so its
  `partition_counts` and `group_count` are full-package counts.
* **Groups:** identity and contamination groups are kept when a sampled task, issue, pull request or repository
  belongs to them, and their member lists are cut to the members in this sample (`member_count` counts those);
  `canonical_id` is unchanged and can name a member that is only in the full package. Like the full package, the
  identity table stores only groups with more than one member, so an id with no row is a one-member group.
* `repo_licenses.csv` covers the 25 sampled repositories (SWE-smith mirrors under
  their upstream name); its `task_rows` counts this sample's agent tasks.

belong to the sampled tasks).

## About the full package

The sections below describe the **full** SWEGraph v3 package; every count in them is a full-package count, not a
count of this toy sample.

### What's new in v3

v2 shipped metadata only: every repository's license was unknown, so the issue text,
patches and tests were blanked, no task was linked to a runnable image, and nothing had been
executed. v3 fixes that:

* **Licenses for 334 repositories**: 331 from the LICENSE/COPYING file at probed base commits (each repository's earliest and latest base commit, plus SWE-smith pinned commits); 2 from deps.dev's current default-branch license because no license file classified (hamba/avro, tokio-rs/axum). deps.dev reports the same license for 255 of them. Text now ships for **77,921 of 83,357 tasks** (93%) whose repository is permissively licensed; copyleft, source-available and undetected licenses keep text withheld.
* **SWE-smith fixes corrected.** SWE-smith's `patch` column is the diff that *introduces* the bug. v2 stored it as the fix. v3 ships the exact reverse as `patch` (the gold fix) and the original as `bug_patch` (the diff that sets up the task) for its 59,136 SWE-smith tasks. In every one of the 21 SWE-smith container runs the reversed fix restored the clean code byte for byte.
* **63,160 of 83,357 tasks linked to their published container image** with digest and size. The rest have none (image not found in the registry: SWE-bench test/dev 49; no per-task image published: SWE-bench train 19,008, BigCodeBench 1,140).
* **Real execution evidence** on a stratified sample: 49 tasks run by us in
  their containers (gold fix twice, a no-op patch, and a git-history audit inside the image),
  48 of which produced test results; 63,131 carry what the source's authors
  executed, marked `upstream_reported`, never as our own pass.
* **A difficulty tier on every task**, by basis: gold-fix size 81,160, not_labelled_by_source 1,140, no public gold patch to size (`unknown`) 506, SWE-bench Verified's human labels 500, swebench_pro_hard_subset+gold_patch_size 39, Pro's `hard` subset 12. Plus `error_message`, `stack_trace`,
  `expected_behavior`, `actual_behavior` and `reproduction_steps` pulled out of the issues,
  repository stars/forks/open issues, language and test framework.

### Licenses and text

| Value | Tasks | Share |
|---|---:|---:|
| included (permissive license) | 77,921 | 93.5% |
| withheld: copyleft (GPL, LGPL, AGPL, MPL) | 4,935 | 5.9% |
| withheld: license not detected | 406 | 0.5% |
| withheld: source-available (BUSL) | 94 | 0.1% |
| withheld: text clashes with a reserved field name | 1 | 0.0% |

The full release's `repo_licenses.csv` lists each repository's license, the file it was read from, every license
seen across its probed commits (`licenses_seen`) and whether it changed between them
(it did for 9: PrefectHQ/prefect (Apache-2.0, none detected at some commits); conda/conda (BSD-3-Clause, none detected at some commits); dagster-io/dagster (Apache-2.0, none detected at some commits); docker/compose (Apache-2.0, BSD-3-Clause); future-architect/vuls (AGPL-3.0, GPL-3.0); psf/requests (Apache-2.0, ISC); redis/redis (BSD-3-Clause, SSPL-1.0); sphinx-doc/sphinx (BSD-2-Clause, BSD-2-Clause AND BSD-3-Clause); ytdl-org/youtube-dl (Unlicense, none detected at some commits)). 61,133 of 83,357
tasks sit at a probed base commit and use that commit's license; every other task uses the
repository-level `spdx`.

### Execution evidence

| Value | Tasks | Share |
|---|---:|---:|
| the source's authors ran it (their harness) | 63,131 | 75.7% |
| never executed (patch and tests only) | 19,008 | 22.8% |
| not executed (unit tests ship with the task) | 1,140 | 1.4% |
| we ran it in its container | 48 | 0.1% |
| tests not published by the source | 30 | 0.0% |

#### Our container runs

Official `swebench` harness for the SWE-bench family; for SWE-smith, the bug patch, then
the reversed fix, then the repository profile's test command. Each task: gold fix twice,
a no-op patch (tests must fail without the fix), and a git-history audit of the image.

| Source | Tasks run | Image runs | Fix passes its tests | Tests fail without the fix | Other tests stay green | Same result twice | No answer in git history |
|---|---:|---:|---:|---:|---:|---:|---:|
| SWE-bench Verified | 8 | 8 | 8 | 6 | 5 | 8 | 8 |
| SWE-bench Lite | 4 | 4 | 3 | 3 | 3 | 4 | 1 |
| SWE-bench test | 4 | 4 | 4 | 4 | 3 | 4 | 0 |
| SWE-bench dev | 2 | 2 | 2 | 2 | 2 | 2 | 0 |
| SWE-bench Multilingual | 8 | 8 | 8 | 8 | 8 | 8 | 8 |
| SWE-bench Multimodal | 2 | 2 | 1 | 1 | 1 | 1 | 2 |
| SWE-smith | 17 | 17 | 17 | 17 | 17 | 17 | 0 |
| SWE-smith (files without a final newline) | 4 | 4 | 4 | 4 | 4 | 4 | 0 |

42 of 49 tasks passed all five core checks. Every result, including the failures, is in the full release's `validation_runs.csv` and on the task (`gate_results`, `validity_status`). None of the 49 container-run tasks is in this toy sample.

What the runs found:

* **The reversed SWE-smith fix**: the bug patch applied cleanly in every one of the 21 SWE-smith runs, and the reversed fix restored the exact clean tree in every one of the 21.
* **Answer leak in SWE-bench images**: 9 of 28 audited SWE-bench runs (SWE-bench Lite 3 of 4, SWE-bench dev 2 of 2, SWE-bench test 4 of 4) found 397 to 4,257 commits newer than the checked-out commit; the image is checked out at the base commit but keeps the upstream repository's later history in its refs and object store, so later commits (where the real fix lives) can be read from git. SWE-bench images are per task: a SWE-bench task we did not run has `git_history_audit = not_run`, not clean. Run tasks are flagged `git_history_audit = leak_found`. Use the safe task setup above for every task.
* **Answer leak in SWE-smith images**: 21 of 21 audited SWE-smith runs (SWE-smith 17 of 17, SWE-smith (files without a final newline) 4 of 4) found 0 to 1,358 commits newer than the checked-out commit; their git history includes branches for *other* tasks' bug commits (`origin/<instance_id>`), so `git log --all` can show where a bug was injected. Tasks on the same image are flagged `leak_found_in_image`. Run tasks are flagged `git_history_audit = leak_found`. Use the safe task setup above for every task.
* **Some source labels do not hold today** in the published image: the gold fix did not pass its FAIL_TO_PASS tests in 1 run (SWE-bench); FAIL_TO_PASS tests already passed without the fix in 3 runs (SWE-bench); a PASS_TO_PASS test failed with the gold fix in 5 runs (SWE-bench). Those tasks are marked (`gate_results`, `validity_status`) instead of hidden.

### The full dataset

The licensed package holds every table above in full **with the issue, patch and test text**,
training partitions, per-entity streams with the complete nested fields
(including each task's full PASS_TO_PASS list), provenance, rights and leak-audit files.
Perpetual, non-exclusive license for internal research, training and benchmarking; models
you train are yours to commercialize; no redistribution of the dataset itself.

## Sources

| Source | Rows used in the full package | License of the source release |
|---|---|---|
| SWE-bench (test, dev, train) | 2,294 + 225 + 19,008 | MIT |
| SWE-bench Verified / Lite / Multimodal | 500 / 323 / 612 (subsets and extensions of SWE-bench) | MIT |
| SWE-bench Multilingual | 300 | MIT |
| SWE-bench Pro V2 (`default`; `hard` recorded as membership) | 642 | MIT tooling; task content under upstream repo licenses |
| SWE-smith | 59,136 | MIT |
| BigCodeBench v0.1.4 | 1,140 | Apache-2.0 |
| SWE-bench org copies of Verified / Lite / SWE-bench / Multimodal | harness fields only (image, log parser, difficulty) and the Multimodal test patches the princeton-nlp copy leaves empty | MIT |

Task content (issue text, patches, tests) comes from public open-source repositories and
remains under each repository's own license. Each repository's license was detected from its
LICENSE/COPYING file at probed base commits, or from deps.dev's default-branch license where
no file classified (`repo_licenses.csv` gives the evidence per repository); verbatim text
ships (in the full package) only for permissive licenses (`code_text_status = included`).

## Licensing

* **This toy sample:** [CC BY-NC 4.0](LICENSE) — attribution, non-commercial — applies to the
  MatrixNorm normalization and packaging layer.
* **Underlying data:** the source releases keep their own licenses (copies included as
  `LICENSE-*-UNDERLYING-*.txt`); repository content stays under each repository's license.
  See [NOTICE](NOTICE).
* **Commercial use** of the normalized package requires the paid license.

## Limitations

* In the full package only a stratified sample was executed by us; the rest carry the source authors' evidence
  (`upstream_reported`). No task is `benchmark_eligible` yet.
* This toy sample is metadata only (text columns empty) and far too small to train or benchmark a coding agent; it shows the schema and the links between tables.
* Not produced, reviewed or endorsed by the authors of any source dataset.
