SWE-agent .traj Parser

Directory Layout

trial_dir/
  <trial>.traj             # JSON: environment, trajectory[], history[], info, context
  <trial>.context.json     # edited/viewed file context (not steps)
  <trial>.patch            # final submission patch
  report.json              # evaluation outcome

The run directory must hold exactly one *.traj file; zero or several refuse detection instead of guessing.

Step Convention

• One step per trajectory[] entry, in array order. Every entry counts, including entries whose action is blank.
• The action is the entry's raw action; actions that are blank after trimming render as their JSON literal so the step survives non-empty action gates losslessly.
• The entry's observation passes through unchanged (empty strings stay empty strings); a non-string, non-null observation is a parse error.
