Long-running build and test commands produce large mixed stdout/stderr streams and re-running them to see different sections wastes developer time and compute resources. This Skill teaches a simple pattern to capture the complete output on the first run so you can inspect any part later without re-executing expensive commands.
Capture the command output on the first run by piping combined stdout and stderr to tee and then read the generated log file to inspect failures or details without re-running the command.

You can capture stdout and stderr by piping the combined output streams to tee, which persists the logs to a file for later analysis without re-running the command.
The best way to save CLI build output is using stream redirection with tee to capture the complete stdout and stderr streams into a readable log file on the first run.
Redirecting command output to a log file saves compute resources and developer time by allowing you to inspect any section of the output later, avoiding the costly re-execution of slow test suites.
Yes, you can run targeted scoped tests first to validate changes, minimizing wasted runs and ensuring you only execute the full suite when necessary.
Stream redirection with tee works for general build and test commands, as well as specific pnpm workflows like pnpm check and pnpm test, to capture durable output.
While tee captures combined stdout and stderr streams into a log file, you must read the generated log file manually to diagnose failures or flaky tests, as it does not parse the output automatically.
