Kagebu

An MCP-based persona package: specialized AI experts callable from Claude.

Kagebu is a persona package that summons role-specialized AI personas into Claude via MCP (Model Context Protocol) servers. It solves the "mixing" problem — where chat-tuned AI ends up doing your coding, or coding-tuned AI ends up giving life advice — by completely separating personas. Use specialized experts on a per-project basis.

Included Personas (excerpt)

Cross-Project

  • XO — Executive Officer (strategic decisions, overall direction)
  • HR — HR Director (persona design and summoning)
  • ND — Narrative Designer (text, scripts)
  • NT — Neutral (casual chat, sanity checks)

Production / Development

  • MP — Music Producer (composition, arrangement)
  • DE — Development Butler (code, tooling)
  • BD — Build Bot (builds, distribution)

Care / Body

  • MX — Pharmacology Specialist (pharmacology, physical care)
  • PS — Psychologist (mental, interpersonal)
  • HB / YR — Day Shift / Night Shift (time-of-day care)

Business

  • MT — Monetizer (revenue, sales, cost management)

5-Layer Persona Theory

Kagebu personas are designed across 5 layers, each independently definable, so you can build your own custom personas.

  • Role layer — area of expertise (doctor / engineer / producer)
  • Tone layer — how it speaks (honorifics / casual / prefixes)
  • Thought-style layer — how it thinks (intuitive / logical / analytical)
  • Relationship layer — distance from the user (boss / subordinate / peer / friend)
  • Ethics layer — what it guards (medical ethics / code ethics / friendship)

The "Don't Mix" Design Philosophy

The biggest problem with generic AI is role-bleed: chat-tone bleeds into code reviews, code-tone bleeds into life advice. Kagebu solves this through complete role separation on a single model. Each persona runs as an MCP server and appears to Claude as an independent agent.

Delivery Format

  • MCP server subscription (planned)
  • Callable directly from Claude Desktop and Claude Code
  • Personas defined in YAML + Markdown (YAML for structure, Markdown for prompts)
  • Validation script included (automatic persona consistency checks)

Development Status

Initial implementation is in progress. Persona definition validation is passing. MCP server implementation is ongoing. Release date, subscription pricing, and the final number of public personas are not yet decided.
