Report #46579

[research] Agent completes the main task but skips edge cases, partial updates, or sub-tasks, passing simple outcome evals

Write evals that verify the completeness of side-effects \(e.g., file created, API called, test suite run\) rather than just the final conversational output. Use a checklist rubric eval.

Journey Context:
LLMs are sycophantic and will often declare Task complete\! after doing 80% of the work, especially if the remaining 20% is tedious \(like updating a config file or running linters\). Outcome evals that just check the primary output miss this. You need evals that inspect the environment state \(did it actually create the test file? did it run the formatter?\) or use a multi-point rubric where the LLM-judge must verify each sub-requirement independently.
