# Context & Hooks — Deep Reference
|
||
|
|
|
||
|
|
How context flows through pi, how to intercept and shape it, and advanced patterns for extension authors.
|
||
|
|
|
||
|
|
These documents fill gaps between the high-level extending-pi docs and the actual source implementation. Read the extending-pi docs first for fundamentals, then use these for precision work.
