EXPANSIONS — what to add as you grow

The kit ships lean on purpose. Three skills, six folders, one framework reference. That's it. As you use it, you'll outgrow the base — this guide tells you what to add, when, and why.

The AIOS structure should look like a small, well-run business. Not a hoarder's basement.


What ships in the kit (don't remove)

Folder / file Purpose
context/ About you, your business, your priorities. Filled by /onboard.
references/ Frameworks, voice samples, API guides, SOPs as you build them.
decisions/log.md Append-only record of what was decided and why.
archives/ Old files. Don't delete — move here.
connections.md Registry of every system your AIOS can reach.
.claude/skills/ Your skills: /onboard, /audit, /level-up. Add more via /level-up.
aios-intake.md Source-of-truth for /onboard. Edit and re-run any time.
CLAUDE.md Root operating manual. Filled by /onboard. Edit when your role/voice changes.

What to add as you grow

Folder / file Add when Why
projects/ You start running 2+ ongoing workstreams that have their own context Active projects need scoped context separate from the evergreen context/ files
templates/ You catch yourself copy-pasting the same prompts or doc scaffolds Reusable, parameterized starting points; reduces drift
brand-assets/ You generate visual content (carousels, slides, thumbnails, images) Centralizes logos, palettes, fonts, voice/tone — the AIOS reaches in instead of guessing
references/sops/ You document how recurring processes run Standard operating procedures the AIOS reads to run things consistently
references/{tool}-api.md You connect a new API or MCP and figure out how it works Researched-once-saved-forever. /audit rewards this; future skills don't re-research.
scripts/ You write Python or Bash to hit APIs not covered by MCPs Most people's second connection is a script, not an MCP
.claude/agents/ You need a sub-assistant for repeatable, multi-step research/writing Agents run on cheaper models in their own context — keep your main session lean
Sub-OS folders (e.g. youtube-os/) You have a vertical with its own data, sheets, transcripts, scripts Isolation pattern — vertical workflows get their own scoped operating manual + skills

Suggested cadences

When each surface gets routinely touched:

  • decisions/log.md — every meaningful decision (/level-up Phase 2 captures these automatically)
  • archives/ — quarterly cleanup; move stale projects, deprecated skills, old intake versions
  • references/sops/ — when a process gets re-run by someone new, write the SOP
  • connections.md — every time a new tool gets wired in, add a row
  • references/{tool}-api.md — same time as connections.md update; capture the API once
  • CLAUDE.md — quarterly review; rewrite the persona/priorities section after /level-up Q90

What NOT to add

Anti-patterns. These look helpful but rot the structure:

  • Don't dump raw email/Slack archives into references/. The wiki is not a doc dump. Interpreted facts only.
  • Don't build folder-of-folders for organization theater. Flat with good naming beats deep nesting. If you need a folder hierarchy to find something, you have a search problem, not an organization problem.
  • Don't add notes/, misc/, tmp/, or inbox/. Graveyards. Use archives/ if it's old, write a real file in the right place if it's new.
  • Don't pre-create folders you don't need yet. Empty folders are noise. The AIOS will tell you when it's time.
  • Don't have parallel decisions.md and decisions/log.md. Pick one. The kit ships decisions/log.md.
  • Don't fork your operating manual. One CLAUDE.md at the root. Sub-OS folders can have their own scoped CLAUDE.md, but the root is canonical.

How to tell when it's time to add a folder

Ask three questions:

  1. Is this conceptually new? Or does it fit somewhere existing?
  2. Will I touch this 3+ times in the next month? If not, it's premature.
  3. Could /level-up route a future skill into here naturally? If yes, the AIOS will use it. If no, you're organizing for yourself, not for the system.

Two yeses = add. One yes = wait.


Your AIOS structure should look like a small, well-run business — not a hoarder's basement. When you can't find something, that's a signal to consolidate, not to add another folder.
