Cast: the project's Who
Personas: hypothetical archetypal actors, grounded in research, that keep the work anchored in who it serves. The process comes from Powell, Keenan and McDaid (2007), which builds on the personas in Cooper and Reimann's Interaction Design.
Mara and Wren are examples: the operators of any agentic project (e.g. agentic-acme), the human
who develops software and the agentic LLM who develops software. They illustrate
the method, not your project.
Each project builds at least one persona of its own, by discussion: the
operator and the agent elicit the actual users of the software under
development (allium's elicit). Add them here. See
applying-personas.md for the process.
(If your software under development is itself an agentic project, Mara and Wren may double as your real cast; the example sits at the meta level it was drawn from.)
