PickBits University — Context Stack Builder (Second Brain, Module 01)

This is a Claude/Codex "skill": a folder with a SKILL.md that teaches your AI
assistant to run a specific workflow.

WHAT IT DOES
  Builds your Second Brain: a context-stack/ folder holding identity.md,
  project-<slug>.md and state.md, plus the CLAUDE.md / AGENTS.md wrappers that
  auto-load them at the start of every session. Your AI stops asking you to
  explain the project from scratch.

  Three paths, picked in the first question:
    A — on your computer (Claude Code, Cursor, Windsurf, Codex CLI, Aider)
    B — in a cloud Project (Claude Projects, ChatGPT Projects, Gemini, M365)
    C — in any chat (claude.ai, ChatGPT, Gemini, Perplexity — free tier is fine)

INSTALL
  Copy the fg-context-stack-builder.skill folder into your project's
  .claude/skills/ directory (create it if it doesn't exist). Then just ask
  Claude to do the thing — e.g. "my AI keeps forgetting my project — build
  my context stack".

BEFORE YOU RUN IT
  Gather 3-5 documents you already work from — the ones that, if your AI had
  them open, would stop you having to explain the project from scratch. A
  brief, some meeting notes, last week's status update, a schema. You don't
  need to write anything new.

A NOTE ON OPENING SKILL.md
  On Windows, double-clicking SKILL.md opens Notepad, which may show a blank
  page — its Markdown view doesn't understand the settings block at the top of
  the file. The file is fine. Open it in VS Code, or choose "Open in Syntax
  View" in Notepad. You don't need to read it to use it.

WHAT'S IN THE FOLDER
  SKILL.md                     the workflow your AI follows
  references/path-a.md         Path A builder prompt (writes files to disk)
  references/path-b.md         Path B builder prompt (cloud Project)
  references/path-c.md         Path C builder prompt (any chat)
  templates/identity.md        who you are, how you want AI to answer
  templates/project.md         one brief per active project
  templates/state.md           this week's working memory
  templates/wrapper-CLAUDE.md  the auto-loader (same content in AGENTS.md)

THE PRACTICE
  60-second daily load. 10-minute weekly reset. That's the whole thing.
