Build Unique AI Agent Personas with Durable Memory

Build Unique AI Agent Personas with Durable Memory

This skill facilitates the design of persistent AI agent personas with distinct voices, durable memory, and specific operational guidelines. It assists users in formalizing recurring AI workflows into named agents, such as those used in portco or fund workflows.

What this skill does

When employed, this skill utilizes Jack & Jill's agent-builder methodology, a structured approach involving 25 questions across 5 phases. The process results in the creation of four essential files, each fulfilling a specific role:

• SOUL.md: Defines the personality, voice, and signature phrases of the agent, while identifying anti-patterns.
• AGENTS.md: Acts as the operating manual for the agent, outlining functional rules and behavior.
• MEMORY.md: Establishes a durable memory framework, allowing the agent to retain cross-session knowledge.
• BOOTSTRAP.md: Provides first-boot orientation to guide initial interactions with the agent.

Who it is for

This skill is intended for developers and teams who work with AI coding agents such as Claude Code, Cursor, or Codex. It is particularly beneficial for those looking to develop and manage internal AI personas for structured workflows.

Use cases

• Creating a dedicated AI agent for specific portco workflows, such as a due diligence analyst or customer support bot.
• Formalizing recurring AI task patterns into named and persistent agents to facilitate consistent operations.
• Developing internal agents as part of structured curriculums like the M6 Product or M9 Ops in the Cobuild curriculum.

Technical details

The skill employs specific tools and frameworks, including agent-skills, aiapplication, and agent-persona-builder, to assist in the creation of distinct AI agent personas. While it draws upon the guidelines outlined in the agent-builder-skill from Jack & Jill, it operates independently to enhance the capabilities of your chosen AI coding agents like Claude Code, Cursor, or Codex.
