Code.
Reviews, refactors, migrations, debugging plans.
Explain a stack trace like a colleague would.
Skips the 'have you tried restarting' opener and gets to the specific failure — what broke, why, and the smallest thing that fixes it.
CODEGet a serious first-pass review before you push.
The critique you should have done to your own PR before your colleague spends their time on it. Structural issues, logic gaps, test holes.
CODERefactor without changing the public API.
The kind of refactor you can actually merge on a Tuesday — internal cleanup, external contract preserved.
CODEWalk me through code I just inherited.
The onboarding read you don't have a colleague to give you. Structure, purpose, gotchas, and the specific parts to be careful about.
CODEBootstrap a single-file CLI.
The 100-line utility you keep meaning to write. Proper argparse, real error handling, ships as one file you can pip install.
CODEWrite a migration script you can sleep on.
Idempotent, reversible, and specific about what it assumes. The script your future-oncall version won't hate you for.
CODERead a postmortem, extract what generalizes.
The pattern that lets you learn from other teams' incidents without reading 40 pages of narrative every time.
