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

onboard 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 4d 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.

Origin

This is a copy

91% identical to onboard — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

When this skill is invoked:

  1. Read the CLAUDE.md for project overview and standards.

  2. Read the relevant agent definition from .claude/agents/ if a specific role is specified.

  3. Scan the codebase for the relevant area:

    • For programmers: scan src/ for architecture, patterns, key files
    • For designers: scan design/ for existing design documents
    • For narrative: scan design/narrative/ for world-building and story docs
    • For QA: scan tests/ for existing test coverage
    • For production: scan production/ for current sprint and milestone
  4. Read recent changes (git log if available) to understand current momentum.

  5. Generate the onboarding document:

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.
