Anthropic

Long-context analysis, careful drafting and codebase work.

Why I use it

Its job in the stack

I use Anthropic models when a task benefits from sustained attention across a large body of text or a complicated repository. They are useful for reviewing architecture, tracing implications and producing a coherent first pass without losing the original brief.

Anthropic complements other models rather than replacing them. The value comes from routing the right work to it, preserving the source context and checking the result against the actual system.

Where it earns its place

Limits

What it does not solve

A polished explanation is not a substitute for running the code or checking the source. External actions remain explicitly authorized.

For your own team

Deciding what belongs in your stack?

Bring the tools you pay for and the decision in front of you to a 45-minute Decision Session. You leave knowing what to keep, what to replace and what can wait.
