Currently,
program.mdinstructs the agent to evaluate runs viagrep "^val_bpb:\|^\peak_vram_mb:" run.log. When a syntax error or OOM crash occurs, thisgrepoutputs nothing. Because the agent never explicitly reads the raw log, it never actually sees the Python stack trace. It just hallucinates what the bug might have been, crippling its ability to 'fix it and re-run.'This PR adds a one-sentence instruction for the agent to run
tail -n 50 run.logif the grep is empty, ensuring it safely acquires the stack trace to successfully self-heal trivial crashes.
