Progressive Disclosure by pattern matching on file path (i.e. Claude "rules")

[nick-anvil]

Claude provides a method of progressive disclosure through "rules"; "rule" context is supplied to the agent if and only if the file being opened matches the "path" associated with the rule.

This is similar to context discovery through "skills", except instead of the discovery criteria being the agent's assessment of skill-task similarity, the criteria becomes simple pattern matching. This eliminates a round trip to the model API and would allow developers to scope context to

• specific directories,
• specific file extensions,
• and other useful patterns.

This feels like a very high SNR mechanism for progressive disclosure.
