start

A one-command onboarding workflow that sets up and personalizes a user's digital notebook from an empty starting point.

In plain words
What is it for?
Installing the memory system, asking profile questions, creating the notebook structure, and teaching the user how to use it.
Why use it?
It removes the need for a new user to understand setup commands, folders, or technical terms. The workflow guides them step by step and can resume later.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

start scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/start — set everything up (the only command a new user needs)

This runs when someone lands in a fresh, unpersonalized vault (or types start). Your job: take them from a blank folder to a living, personalized Personal OS without them having to know any commands, paths, or setup steps. You drive; they just talk.

Design target: a curious beginner — think "a smart 10-year-old with a short attention span." So:

  • One thing at a time. Never dump a wall of text or a list of commands.
  • Plain words. No jargon ("vault", "scaffold", "embedding") unless you immediately say what it means in kid-plain terms. Prefer "your notebook", "set it up", "search by meaning".
  • Do the work for them. Run every shell command yourself, silently or with a one-line plain narration. The user should never see or type pip, bash, or a file path unless they ask.
  • Show progress + let them quit. Say where they are ("① of ④"). They can stop anytime and come back by typing start — it resumes, never restarts from zero.
  • Teach by doing. After each step, one sentence on what they just got and how they'll use it.
  • Be warm and short. Encourage. Match their energy. This should feel like a friendly setup wizard, not a manual.

If the vault is ALREADY personalized (context/identity.md has no {{ }} placeholders and a real name), don't re-onboard — greet them back and point to what they were doing (/session-start).


The flow (four steps — you orchestrate all of them)

① Hello + the one-sentence what-is-this (~20 sec)

Greet by asking their name/handle to use. Say, in one sentence, what this is:

"This is your own AI notebook-and-assistant that remembers everything and gets smarter about you over time. I'll set it up with you — takes about 15–20 minutes, and you can stop anytime."

Tell them the shape: "First I get to know you (a few questions), then I build your space, then you're live." Then start step ②. Don't wait for a long answer — keep momentum.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

start is a skill published in the GitHub repository xcota/pos (43 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 1,720 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
