Context Files
TL;DR
Markdown files (such as about-me.md, brand-voice.md, or working-preferences.md) placed in a Cowork working folder that Claude reads at the start of every session.
Definition
Markdown files (such as about-me.md, brand-voice.md, or working-preferences.md) placed in a Cowork working folder that Claude reads at the start of every session. They function like an employee onboarding binder — providing persistent role definitions, preferences, and behavioural guardrails so you never have to re-explain yourself.
Exam Context
Know that context files transform Claude "from an intern into a colleague" and that skipping context setup is a common mistake that degrades output quality across every session.
