Rapidly save an idea, reference, or thought into inbox/ before it's lost.

When to Use

User wants to quickly save an idea
Capturing a URL, quote, or reference
Recording a fleeting thought during other work
/rulebased-second-brain:capture invoked

Procedure

Determine content: Ask the user what to capture if not provided. Accept:
- Free-form text
- A URL or reference
- A question to explore later
- A code snippet or command
Generate filename: inbox/YYYY-MM-DD-<slug>.md (kebab-case from title or first meaningful words)
Create the note following system/conventions.md frontmatter rules:

---
title: <extracted or provided title>
created: YYYY-MM-DD
tags: [<auto-suggested tags, max 3>]
status: seedling
source: <URL or context if available>
---

<captured content>

Auto-tag: Suggest up to 3 tags based on content. Common categories:
- Domain: dev, design, business, personal, reading
- Type: idea, reference, question, quote, snippet
Confirm: Show the created file path and a one-line summary.

Rules

Never ask more than one clarifying question. Capture fast, organize later.
If inbox/ doesn't exist, create it.
If content is ambiguous, capture it anyway with a #question tag.
Preserve the user's original wording. Don't rewrite or summarize unless asked.
Multiple ideas in one message → create multiple notes.
Follow system/conventions.md for frontmatter fields and naming.

Output

Captured → inbox/2026-03-19-<slug>.md
Tags: #idea #dev
