small-ow-agent-bench (catalog)

Frozen compact-shell system reliability for compact open-weight coding agents — not coding IQ.

This dataset is not the Harbor task dump. Each of the 62 rows is catalog metadata plus the agent-visible instruction:

  • id, skill, difficulty, bank
  • trap_id / trap (failure-mode label from TRAPS.md)
  • instruction / instruction_summary
  • license, GitHub tag, compact-shell version

It does not include hidden verifiers: tests/, solution/, foils/, gold file lists, mutants, or environment/repo. Those stay in Harbor tasks/ on GitHub.

Do not train on this 62-item bank and then report the same items as evaluation.

Compact-10 (v1.0.1)

Headline = five-skill macro mean. Micro = successes / 186. Artifact does not require finish; Clean does. Halt (Artifact=1, not clean) = 105. 12×62×3 = 2232 scored trials.
