Agent Foundations: Your Personal Second Brain
Build in Claude or ChatGPT: as a Project, in Cowork, or a local folder for Claude Code
Everything in this programme is built on one asset: your personal second brain - a portable folder of context files about you, your work, and your goals that any agent can read. In this first session you build it, with your first purpose-built agent running on top. Most people shape it as a personal strategy coach that knows their background, their goals, and the patterns that hold them back. Every session after this one builds on it.
What you'll build
- Your first agent, in the container that fits you: a Project in Claude or ChatGPT, a folder-backed Cowork agent, or a local folder for a coding agent
- The seed of your personal second brain: context files that capture your work, your team, and how you think, so the agent stops giving generic advice
- Custom system instructions generated through a guided, coaching-style interview
- A background knowledge base, built with Deep Research, that your agent draws on every day
What you'll learn
- How agents actually work: the brain (the model), the context (memory and files), and the tools it can reach for
- What a second brain actually is - a portable folder of context files any agent can read - and why it beats relying on chat memory or clever prompting
- When to use a Project, when to use Cowork, and when to reach for a coding agent
- The art of context management: freshness, file size, relevance, and the file structures that make agents remember what matters
Going further (advanced)
- Already using Claude Code daily with one endless chat and no context files? This is where you split that into a CLAUDE.md and a context-file structure your agent reads every session - the upgrade past technical participants said paid off most
- Structuring the folder so the same brain works from Claude, ChatGPT, a coding agent, or whatever comes next
What you won't get anywhere else
I'll share two prompts I've refined over months of daily use: an Interview Prompt that interrogates your communication style, decision-making, and blind spots to generate deeply personalised instructions, and a Personal OKR Prompt that gets you crystal clear on what you're actually optimising for. One Cohort 3 graduate called building his second brain 'a game changing moment'; another called this session 'the biggest single breakthrough' of the programme.
