   Part 1 2 min

   The reasoning partner

   One frontier model you use all day to think, draft, critique and analyze. Not for any one task, but for the everyday work of thinking a problem through with something that argues back.

2. 

   Part 2 2 min

   The prototyping tool

   It turns a description into a working, clickable thing without an engineer. This is the tool that replaces the spec, and the clearest sign of how the job has changed.

3. 

   Part 3 2 min

   The agentic coding tool

   Reading code, writing queries and building small tools, even if you never ship a line to production. Whether you can do this now divides the two versions of the job.

4. 

   Part 4 2 min

   Direct access to your data

   Answering product questions yourself, today, without filing a ticket.

5. 

   Part 5 2 min

   Research synthesis

   Turning a pile of unstructured text (transcripts, session notes, open-ended survey answers, tickets, call recordings) into an answer to one question: what are people telling us?

6. 

   Part 6 2 min

   The eval harness

   Measuring the quality of anything model-powered that you ship: a place where your test set, rubric and scores live, and a command that tells you whether the number moved.

7. 

   Part 7 2 min

   The system of record

   The least glamorous category, and the one that decides whether half the others work.

8. 

   Part 8 2 min

   The watcher

   Every other category answers a question you asked. This one raises questions you didn’t know to ask.
