As you work in a file, Yggdrasil can point out when that file looks structurally unusual next to its neighbours — a quiet nudge to read it a little more carefully. It is only ever a hint: it never blocks a check, never fails a build, and never changes whether your code passes.

What you see

When you ask for a file's context (yg context --file) and that file stands out structurally from the other files around it, the output ends with a single plain line:

This file is structurally unusual among this node's other TypeScript files — worth a closer read; no action required.

That is the whole thing at the file level — no score, no ranking, no breakdown of what stood out, just the one line, and only when it genuinely applies. It appears only while the note still matches the file's current contents; edit the file and it stays silent until the next check refreshes the picture. There is one other surface: yg advise prints a single aggregate line counting how many files across the repo currently stand out structurally, pointing you back to yg context --file where each lives.

What "structurally unusual" means — and what it doesn't

Yggdrasil keeps a small, rough shape for each file: how big it is, how deeply nested it gets, and how many functions, classes, imports, branches, calls, and literals it holds. A file is flagged only when that shape sits far from the shape of the other files in the same node, written in the same language.

Two honest limits follow from that, and they matter:

• It is relative, never absolute. A file is only ever compared with its own node's other files in the same language — a Python file is never measured against a Java one. The line means "this file is unlike its neighbours," not "this file is bad." A perfectly good file can be the odd one out; a genuinely messy file surrounded by equally messy siblings will say nothing.
• It needs enough neighbours to compare against. A node needs at least five files of the same language before the hint can fire at all; with fewer than that there is nothing to stand out from, so it stays quiet.

Treat the line as an invitation to look, not a verdict. Often the closer read simply confirms the file is fine — that is a normal, expected outcome.

Turning it off

The hint is on by default. To silence it, add this to .yggdrasil/yg-config.yaml:

signals:
  attention: false

signals is an optional section; its only setting today is attention, which must be true or false. With it off, the line never appears — and nothing else changes either way, because the hint has no effect on any verification result. See Configuration for the full config reference.
