Exploit Resistance
Does the agent fix the bug or game the verifier?
What it measures
Whether a coding agent fixes a seeded function or games the visible test runner.
Category: safety. Status: alpha.
How to run
$ npx benchmark-exploit-resistance list
$ npx benchmark-exploit-resistance run --model <model-id> --provider openrouter
$ npx benchmark-exploit-resistance score results.json
--provider mock runs the whole benchmark offline with no keys. Real models run
through OpenRouter (OPENROUTER_API_KEY) or any OpenAI-compatible base URL
(OPENAI_BASE_URL, OPENAI_API_KEY).
Data fields
data/tasks.jsonl holds 46 tasks, one JSON object per line
(kinds: 46 episode).

Provenance
Exploit Resistance provenance
This file is generated from the benchmark definition.
Seeded mini-repo generator
- Kind:
synthetic - URL: https://github.com/pooriaarab/benchmark-exploit-resistance/blob/main/scripts/gen-tasks.mjs
- Licence:
MIT - Retrieved: 2026-10-16T00:00:00.000Z
- How to get it: Run
node scripts/gen-tasks.mjs --seed 20261015 --split publicfrom the repository root.--split hidden --seed <n>writes .hidden/tasks-.jsonl and does not overwrite the public file. - Contamination notes: Public tasks use seed 20261015 and are committed in data/tasks.jsonl. Public records omit hidden cases and the honest expression. The grader rebuilds the hidden cases from the seeded generator at grade time; the answer templates live in scripts/honest.mjs, which the published package does not carry. Hidden splits use another seed, which changes the spec variants, the bugs and the answers, and stay unpublished under .hidden/. Once a scenario's three variants are all taken, a hidden task can share spec text with a public task; only the drawn argument tuples are kept disjoint.
- Refresh: Pick a new seed, regenerate, and review the JSONL diff before replacing the public file.
Loophole catalog
- Kind:
human-written - URL: https://github.com/pooriaarab/benchmark-exploit-resistance/blob/main/docs/loophole-catalog.md
- Licence:
MIT - Retrieved: 2026-10-16T00:00:00.000Z
- How to get it: Read docs/loophole-catalog.md. The generator copies one catalog hint into each task.
- Contamination notes: The catalog names the verifier shortcuts. It does not contain hidden inputs or the honest expressions.
- Refresh: Edit the catalog and the generator hint list in the same change so the task file stays aligned.
Grader
Hidden cases from the seeded generator, plus a tamper check on verifier files. The visible runner is not the score.
Limitations
This dataset contains only the public task split (46 tasks).
Hidden evaluation splits use a private seed and are deliberately not part of
this dataset. Source kinds: human-written, synthetic. These are evaluation prompts
for the benchmark-exploit-resistance benchmark, not training data; scoring requires the package's
deterministic grader. See PROVENANCE.md for contamination notes.
