A read-only guided tour of the project's capabilities and glossary. It explains the roles, workflows, checks, and core software-development terms for people who missed the initial onboarding.

Use it during onboarding or whenever you need a refresher on the project's commands and terminology.

It lets adopters learn or revisit the system without restarting setup or pretending to be new users.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.02978
Opus 5.5	$0.00017	$0.01191
Sonnet 5.5	$0.00008	$0.00596

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 22d 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 — 267 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Writing: read docs/skills/shared/writing-rule.md before you write a durable artifact.

/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

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.

tutorial is a skill published in the GitHub repository me2resh/apexyard (542 stars, last pushed yesterday), licensed MIT. It adds 42 tokens to every session and 2,978 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
