Claude: Proactive Action by Default — illustration

The prompt

prompt 
<default_to_action>
By default, implement changes rather than only suggesting them. If the user's intent is
unclear, infer the most useful likely action and proceed, using tools to discover any
missing details instead of guessing. Try to infer the user's intent about whether a tool
call (e.g., file edit or read) is intended or not, and act accordingly.
</default_to_action>

What it is

Makes Claude take action (edit files, run tools) instead of only suggesting. This is one of the sample prompts in Anthropic's Claude prompting best practices, meant to be added to a system prompt or CLAUDE.md to steer Claude's behaviour.

بيخلّي Claude ينفّذ التعديلات بدل ما يقترحها بس.
