Overview

This skill manages the full persona lifecycle: rapid generation, persistent registry, data-driven evolution, quality auditing, and distribution to downstream agents. It transforms diverse inputs into consistent, Echo-compatible persona artifacts and maintains confidence, versioning, and evolution logs. Use it to ensure agents share a single source of truth for user archetypes.

How this skill works

Cast ingests multi-source inputs (research notes, session traces, feedback, analytics, and code context), synthesizes persona attributes, validates them against the Echo persona template, and registers them in a central registry. It assigns confidence scores with provenance, records evolution history on every change, and adapts persona outputs to the format required by consuming agents. It also exposes commands for conjuring, fusing, evolving, auditing, distributing, and TTS-based speaking.

When to use it

• Generate personas quickly from project files, docs, or limited research (CONJURE).
• Fuse interview data, session logs, feedback, and analytics into existing personas (FUSE).
• Evolve personas when new behavioral or metric evidence appears (EVOLVE).
• Audit the registry for freshness, coverage, duplication, and confidence issues (AUDIT).
• Deliver adapted persona packages to UI validation, feature ideation, or retention agents (DISTRIBUTE).
• Produce persona voice outputs or dialogues for narration and testing (SPEAK).

Best practices

• Always ground attributes in source evidence and mark inferred fields explicitly.
• Preserve Core Identity; create a new persona if the role or category fundamentally changes.
• Register every persona and append an evolution log entry on each update.
• Score confidence and apply decay rules; flag low-confidence personas for review or archival.
• Validate persona artifacts against the Echo template before distribution.
• Ask for human decisions when merges conflict, confidence is low, or multiple targets exist.

Example use cases

• Conjure starter personas from a service README and sample telemetry to kick off design work.
• Fuse interview transcripts and session replay clusters to enrich persona goals and pain points.
• Run a registry audit to surface stale or duplicate personas and produce remediation tasks.
• Distribute Echo-compatible persona packages to a UI validation agent and a product ideation agent.
• Generate voiced persona reactions for prototype demos or automated usability scripts.
