Platforms promise everything; scripts deliver one fix today.
The Unix philosophy persists because composition scales: small tools with clear stdin/stdout, piped together, versioned in repo, owned by the team.
Your personal toolkit — aliases, one-off CLIs, pre-commit helpers — saves minutes daily. Minutes compound to weeks annually. Document scripts in README snippets so they survive laptop swaps.
Before buying another platform seat, ask: could a 40-line script solve 80% of this?
Small tools are how senior engineers keep leverage without waiting on procurement.
