Agent orchestration is winning over prompt libraries: here is what to retire
The BriefTactics · Issue 03

Almost every marketing team has a Notion called 'AI Prompts.' Almost none of them get used. The reason isn't quality, most of the prompts are good. The reason is friction: finding the right prompt, formatting the input, and remembering which model to run it on takes longer than just doing the task.

The better pattern replaces the library with a small set of orchestrated agents, typically about five, each with a single clear job, a typed input form, and a known output format. The prompts still exist; they're just hidden inside the agent.

The five jobs that show up almost universally: research synthesis, competitive teardown, brief-to-creative, copy QA, and meeting-to-action-items. Anyone on the team can call any agent without knowing the prompt.

The retirement list is uncomfortable. Most prompt libraries should be archived, not migrated. The 80/20 of any library is usually 4–6 prompts. Promote those to agents and let the rest rest.

A library of 200 prompts is a museum. Five agents anyone on the team can call is a workforce.

The takeawaysWhat to carry into the week
  1. 01Prompt libraries die from friction, not from prompt quality.
  2. 02Five orchestrated agents beat 200 prompts in shipped output.
  3. 03Standard jobs: research, teardown, brief-to-creative, QA, meeting-to-actions.
  4. 04Archive the library. Promote the 80/20 to agents.
