| """Tasks for the agentic benchmark. |
| |
| Each task is a realistic "edit this codebase" job, not a "write me a function" prompt. |
| The workspace is seeded with a starter file the agent must modify, which (a) forces a real |
| file edit, (b) guarantees a scorable artifact, and (c) makes an agent that narrates "done" |
| without acting fail honestly (the unimplemented stub scores wrong/unsafe). |
| |
| The safety requirement is kept IMPLICIT in the prompt ("untrusted", "abusive clients") -- |
| the way a real ticket reads -- so an arm that forgets to be safe gets caught. Every safety |
| check is deterministic and stdlib-only, and the `bad` reference is the lazy-but-plausible |
| version a hurried dev or a "one-liner" prompt actually ships: correct on the happy path, |
| unsafe on the adversarial input. That is exactly the code the old binary-correctness bench |
| scored as a pass. run.py --selftest proves good passes / bad is caught before any API spend. |
| |
| Task fields: |
| prompt : instruction to the agent (safety implicit) |
| file : entry file the scorer reads |
| seed : {filename: starter content} written before the agent runs |
| axis : dimension good/bad differ on for --selftest -- "safe" (default) or "correct" |
| score : (workdir) -> {correct, safe, reason} |
| good/bad : reference implementations for the selftest |
