Overview

Heavy Thinking amplifies reasoning on complex analytical, strategic or creative tasks — spawning independent parallel working agents and synthesizing their outputs through critical deliberation, so hard questions get more than a single reasoning pass.

What it does

• Parallel agents — several independent lines of reasoning at once.

• Critical synthesis — deliberation across their outputs, not a vote.

• Depth on demand — for analysis, strategy and creative problems.

• Fewer blind spots — catches what one pass would miss.

• Better answers — where the stakes justify the effort.
  
  

How to use it

1. Bring a genuinely hard question.

2. Ask Shadow to think heavily on it.

3. Shadow reasons in parallel and synthesizes.

4. Get a deliberated answer — with the thinking shown.

Run it in-app or from Claude / ChatGPT via the Shadow MCP.

What it needs

A complex, high-stakes question worth the extra compute.

What you get

A deliberated answer: multiple reasoning passes synthesized into one stronger conclusion.

Not the right skill when…

• You want a simple lookup → just ask Shadow directly, instead

• You want a defined workflow → use the specific skill, instead

• You want casual conversation → this is overkill, instead
