agent-shell: your output, your storage

agent-shell: stop spilling your outputs since the beginning of time, ai agents have wanted one thing at one thing only: redirecting stderr to stdout then piping the output to head or tail or grep or sed or awk. That’s all they really want. Except, they do it wrong the majority of the time (because “ai labs” are fundamentally incompetent at software engineering, as we’ve previously discussed before). Common ones I see routinely which are painful and require manual “reminders” into the agent to stop: uv run my-big-honking-test 2>&1 | grep -E "failed:|error:" | head -5 but then the test fails with a non-zero error code, the grep reports an error count, so then the agent RE-RUNS THE ENTIRE TEST with a different grep failure to “find the failing test case” except, the failing test case grep requires “guessing the future” regex, but the first attempt at “guessing the error regex” fails, then code agent continues re-running a 20 minute test suite with different grep filters until you remind…
