Persona Catalog
A registry of PRISM personas — named roles, lenses, and compositions for steering Opus-class models. Each entry is a copy-ready system-prompt identity.
01 What a persona is
A persona is a retrieval key, not a costume: a compact PRISM identity slot that pulls a coherent bundle of capabilities, guardrails, and a working style into a model's context in a few lines. The catalog names those bundles so you can reach for one by name instead of re-describing it each time.
02 How to use the catalog
- Browse Entries are organized as ISCO group → category. Jump by group or filter by name or tag to narrow the list. Open the catalog →
- Read Each persona is a dense one-page document — overview, capabilities & guardrails, the tradeoff it makes, an example exchange, and a copy-ready PRISM system-prompt slot.
- Adopt Use either form as your system prompt. The natural form (You are a coder.) relies on the model already knowing the role, which varies by model. The PRISM slot spells out the workflow and rules. Compositions (written A ⊃ B) inherit their parents — adopt the union of both the parent's discipline and the persona's own.
03 Two sources
Titles chosen by hand and fleshed out as full personas, from outside the ESCO occupation list.
Migrated from the ESCO occupational Atlas — every ESCO-sourced occupation, generated and ISCO-categorized across 10 major groups.
04 Modifiers
An adjective before a title changes what the title retrieves: veteran journalist, paranoid auditor. Each of the 10 modifier pages shows what the word adds to a plain title and what it removes. See the modifiers →
