code_e2e.jsonl is the real WebCode E2E task set from Exa. It is not committed — it carries
secret-shaped test fixtures (one task probes secret detection, so it contains example tokens/keys that trip
GitHub push protection) and is 656K. Fetch it:
examples/webcode-matrix/data/fetch.sh # → code_e2e.jsonl (33 tasks)
# or set WEBCODE_DATASET to a code_e2e.jsonl path (e.g. a checkout of exa-labs/benchmarks)- Source: https://github.com/exa-labs/benchmarks (
webcode-benchmark/data/e2e/code_e2e.jsonl, MIT) - Blog: https://exa.ai/blog/webcode
- Schema per row:
{ id, slug, repo, repo_url, release_tag, task_description, test_patch, metadata }.metadatacarriescitations(required knowledge),dockerfile(the per-task toolchain image), andsolution_files(the file the agent must produce).
Exa ships the dataset only — "No agent harness included — bring your own." The harness×model matrix in
../webcode-matrix.ts is that harness.
