Context pointer

Also called: context pointers, doc pointer, file reference, see also link

A short mention in one document that tells an agent where to find more, such as 'deployment steps are in the deploy guide'. The agent opens the other file only when the task needs it, which keeps the context window small.

For example: Instead of pasting the whole style guide into AGENTS.md, a team adds one line pointing to it, and the agent reads it only when writing customer-facing text.
