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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00051 | $0.01720 |
| Opus 5 | $0.00026 | $0.00860 |
| Sonnet 5 | $0.00010 | $0.00344 |
| Haiku 4.5 | $0.00005 | $0.00172 |
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.
