Add context: @file, @folder, selection, paste

By default the Coach has read the whole book and treats it evenly. Want to spotlight Chapter 3 plus character notes? Four ways.

Four ways

1 · @file

Type @ in the message box → file search drops down:

@Chapter 3
@Protagonist
@Timeline

The Coach treats these files as priority context — weighted above the rest of the book.

You can @ several:

@Chapter 3 @Protagonist — check whether J. Doe's reaction makes sense

2 · @folder

@ + folder name:

@Notes/Characters

Every file inside the folder joins priority context.

Good for "I want all character notes weighted up this round."

3 · Selection

Highlight text in the editor → the Coach panel shows "N characters selected".

Ask a question, and the AI treats that selection as highest-priority context:

Selected: "Lighthouse keeper J. Doe had worked the reef station for thirty years."
You ask: "smooth this out"
The AI smooths that sentence.

4 · Paste

Paste text directly into the message box (or drop a file in):

• Text → treated as "this is what we're discussing / revising"
• File (.md / .txt / .docx) → parsed and added as context

Good for external content (a chapter a friend sent, someone else's draft).

Priority layers

Four priority levels in the Coach's context:

1. Selection / paste  (highest — the active object)
2. @file / @folder    (priority reference)
3. writing-spec.md    (behaviour rules)
4. Whole book         (background)

Higher overrides lower on conflict.

Limits and best practice

• Per-message context capacity is bounded (~200K tokens) — @-ing every file at once may get compressed
• Long chats auto-compress old context — pin or summarise important conclusions (Advanced behaviours)
• Edits to a file refresh context immediately — @ Chapter 3, edit Chapter 3, the next message sees the new version
