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 B, and why

tutorial scanned grade B with 1 finding 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/tutorial — Replay the Capability Tour

This is ticket #911 (M3) of the guided-onboarding walking skeleton (technical design: docs/technical-designs/onboarding-increment-1.md, § D3/D4 and the "Standalone /tutorial Reusability Spec"), layered with increment 2's depth adaptivity (ticket #914, § D2/D5/D7) and now grown by #915 (M7) to also render the full teach-in-context glossary — US-6 in full (technical design: docs/technical-designs/onboarding-increment-2.md § D5). /tutorial is a standalone, read-only re-entry point to the same capability tour /onboard shows on first run, plus the plain-language glossary for the five core SDLC terms — for the adopter who skipped either, missed them, or just wants to see them again without faking a fresh fork.

#914 wired /tutorial onto the shared depth-mode marker so it renders in the adopter's current terse/guided mode (one short "why this matters" sentence per section in guided mode; bare, byte-for-byte unchanged rendering in terse — NFR Backward-compat). This ticket (#915) adds the full glossary render after the tour — reading the same shared docs/onboarding/glossary.md asset /onboard's guided-mode asides already read one term at a time (#913) — and lifts the "tour-only" scope note from Rule #4 below. It does not touch the depth-mode marker's derivation, override, or transparency logic (that stays #914's, unchanged), and it does not touch /onboard's asides or the glossary content itself (that stays #913's).

What this skill does NOT do

/tutorial is deliberately disconnected from /onboard, /setup, and /handover — it must work identically whether the fork is fresh, already configured, or predates this feature entirely (US-6 AC). Concretely, it never:

  • Reads or writes onboarding.yaml
  • Triggers fresh-fork detection (it does not call fresh_fork_state() — see .claude/hooks/_lib-fresh-fork.sh — for gating; that function exists for /onboard and the SessionStart hook, not for this skill)
  • Runs any part of the /setup or /handover flows
  • Writes to apexyard.projects.yaml or any other registry
  • Touches the active-ticket marker or the bootstrap marker

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.
