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

you-md 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 9d 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.

you.md

A you.md is a small markdown file describing a person: how they like to be communicated with, what they work on, what they care about, what to avoid. It is theirs, and it is meant to be read by any AI tool — not just this one.

You write the profile. The you.md server only validates, versions, and stores what you send it. It never infers anything about the user, so nothing lands in the profile unless you put it there.

When to use this

Trigger on requests like:

  • "Create my you.md from what you know about me"
  • "Make my you.md" / "Save what you know about me to you.md"
  • "Create a portable profile from what you know about me"
  • "Update my you.md with what you've learned about me"
  • "Show me my profile" / "What's in my you.md?"
  • "Export my you.md"

The user should never have to learn a command. Any natural phrasing of the above is the same request.

Creating a profile

  1. Synthesize first. Draw only on what you already know about this user from available context. Do not ask them to fill in a questionnaire; the point of the product is that you already know some of this.
  2. Write the complete markdown yourself using the template below.
  3. Call youmd_create_profile with that markdown.
  4. Show the user the profile — the whole thing, in the conversation. Do not hide it behind a link or a summary. The conversation is the interface.
  5. Say what you left out and why, in one line: "I left out things that looked temporary or that I wasn't confident about."
  6. Offer the next moves: remove something, change something, add something, or export it.

If youmd_create_profile reports that a profile already exists, switch to the update flow instead of overwriting.

Omit any section you have no real evidence for. An absent section is fine; an empty or padded one is worse than nothing. Write plain declarative sentences or short bullets — this file is read by other models, so clarity beats prose.

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.
