When you ask Composer to do something complex, like reviewing a full contract or researching a legal question, you’ll notice it doesn’t respond immediately. Instead, you’ll see status indicators showing what it’s working on. This is the Thinking phase.

Why Composer pauses to think

Simple questions get fast answers. But contract review isn’t simple. A request like “review this MSA for risk” requires Composer to:
  • Read the entire document
  • Identify which provisions matter
  • Check each one against your standards
  • Decide what needs to change
  • Generate redlines with explanations
Doing all of this well requires planning. The Thinking phase is where that planning happens.

What happens during thinking

Composer works through your request in stages: First, it breaks down the problem. A broad request becomes a series of specific tasks. “Review for risk” turns into checks on indemnification, liability caps, termination rights, IP ownership, and so on. Then it makes a plan. For research, this might mean formulating search queries. For contract review, it means deciding which clauses to examine and in what order. Then it executes. Composer works through each planned step: reading sections, applying playbook rules, comparing against your template, or searching external sources. Finally, it synthesizes. The findings from each step get combined into a coherent response with redlines, comments, or a summary.

Status indicators

During thinking, you’ll see what Composer is doing:
  • Reading document
  • Reviewing specific clauses
  • Applying playbook
  • Searching web sources
  • Generating redlines
These indicators give you visibility into the process, not just the final output.

The benefit of step-by-step processing

This approach takes longer than a single-pass response, but produces better results:
  • Fewer errors because each step gets validated before the next one starts
  • More thorough analysis because nothing gets skipped
  • Clearer reasoning because the AI plans before it acts
  • Better redlines because changes are informed by full document context

When to expect thinking

Composer uses extended thinking for:
  • Full contract reviews
  • Multi-document comparisons
  • Research requests
  • Compliance checks
  • Chained workflows (review → draft → summarize)
Quick factual questions (“What’s the governing law?”) skip the thinking phase and return immediate answers.
