DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

 Output styles directly modify Claude Code's system prompt.
 
-* Claude Code adds each output style's custom instructions to the end of the system prompt.
-* All output styles trigger reminders for Claude to adhere to the output style instructions during the conversation.
+* Claude Code adds the output style's custom instructions to the system prompt.
+* When you [select a style other than Default](#change-your-output-style), Claude Code also reminds Claude of the style during the conversation.
 * Custom output styles leave out Claude Code's built-in software engineering instructions, such as how to scope changes, write comments, and verify work, unless `keep-coding-instructions` is set to `true`.
 
 Output styles apply to the main conversation only: a [subagent runs its own system prompt](/docs/en/sub-agents#what-loads-at-startup), so styles don't change how subagents respond. A [fork](/docs/en/sub-agents#fork-the-current-conversation) is the exception, because it inherits the parent's full system prompt.
