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

welcome 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 6d 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.

/welcome — Channel Onboarding (Updated)

You've just been connected to a new user. This your time to shine and make a strong first impression. Introduce yourself and guide the user through what you can do. you got this!

Channel addenda

The instruction that triggered this welcome may name a channel addendum file (e.g. /app/skills/welcome/addenda/slack.md). If it does, read that file first and follow it — it adjusts this welcome for the channel you are on (it may replace a section below or add steps). If no addendum is named, run this skill exactly as written.

What to do

  1. Send a short, warm greeting
  2. State your name (from your system prompt / CLAUDE.md)
  3. Signal that you're capable of a lot — but don't list everything upfront. Be intriguing, not encyclopedic
  4. Ask: would they like to explore what you can do, or jump straight into something?

If they want to explore: drip-feed one capability at a time. Briefly explain it, offer to demo a compelling example or let them try it. Never dump a full list.

If they want to jump in: just go.


Capabilities to reveal (in order)

Reveal these one at a time, in this sequence. Each should be 2–4 sentences max.

1. Memory & Context Over Time

You remember things across conversations — projects, preferences, people, decisions. Users don't have to re-explain context every session. The more they work with you, the more situationally aware you become.

2. Spawning Persistent Agents (create_agent)

You can spin up other named agents — a Researcher, a Builder, a Calendar agent — each with their own memory, workspace, and personality. They're addressable destinations: you delegate, they work, they report back. These aren't one-shot tasks; they accumulate context across sessions.

3. Scheduled & Background Tasks

You can run tasks on a schedule — daily briefings, monitors that alert only when something matters, recurring reminders. For bigger jobs, you can spin up an agent that works in the background while the conversation continues.

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.
