# Build Claude instruction
instruction="You are creating a new $type entry as a YAML-frontmatter .mdx file.

=== USER INPUT ===
Type: $type
Title: $title
Preview: ${preview:-"(none)"}
Slug: $slug
Date: $date
${extra_prompt:+Extra: $extra_prompt}

=== TARGET FILE ===
$target_file

=== YAML FORMAT ===
The file MUST use this exact YAML frontmatter structure:

---
title: $title
slug: $slug
type: $type
category: <choose-appropriate-category>
start_date: '$date'
end_date: ''
state: active
preview: ${preview:-"<write-a-one-line-preview>"}
status: Draft
confidence: <certain|likely|possible|unlikely>
importance: <1-10>
tags:
  - <tag1>
  - <tag2>
  - <tag3>
---

Content goes here...

=== YOUR TASK ===

1. ANALYZE the title and preview to determine: category, tags, confidence, importance.
2. WRITE the .mdx file to: $target_file
3. Use the Write tool to create the file with proper YAML frontmatter.
4. VERIFY the file was created.

Execute this now without asking for confirmation."
