 AI *may* be used to understand the codebase for E-easy+E-has-instructions contributions, but not to write any code.
 
-This policy was adapted from [uv's AI policy].
+When using AI to author changes to *analysis* - the code responsible for analyzing Rust code and not for implementing IDE features, including
+but not limited to: type inference, MIR, name resolution, macro expansion - generally anything in the crates `parser`, `mbe`, `hir-expand`, `hir-def`, `hir-ty`,
+although there are exceptions; **including when using AI only to analyze bugs and not to write code**, you are required to include a citation
+of the rustc code responsible for the change you did, along with an explanation of how your change follows from it in case this is not immediately clear.
+
+The reason for that is that it is almost impossible to be fully correct in analysis if we implement things differently from rustc. We should not guess
+how to fix bugs in analysis without looking at the rustc code.
+
+This policy was inspired by [uv's AI policy].
