Bumps tutorial coverage from the v2.1.217 baseline (2026-07-22 sync) to v2.1.220 — three contiguous releases (v2.1.218–v2.1.220). Critical fixes: - Nested subagent spawning is on by default again at depth 3 (v2.1.219). Five locations across 04-subagents, CATALOG, 10-cli and QUICK_REFERENCE stated it was disabled by default — true for v2.1.217–v2.1.218 only. CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH=1 now disables rather than enables. All five carry an identical three-era history note. - Claude Opus 5 is the default Opus model (v2.1.219). 10-cli asserted "Opus 4.8 remains the default"; Opus 5 was absent from every model table. Added to both model tables, 19 Compatible Models footers, and ~20 effort-level enumerations. Also fixed: fast-mode model list, auto-mode eligibility self-contradiction in 09-advanced-features, stale CLAUDE_CODE_ENABLE_AUTO_MODE opt-in in CATALOG, hook-event count disagreement (29/30 -> 31 across three files), doc-generator skill name/directory mismatch, stale "May 2026" headings, and the last three docs.anthropic.com links. Added: DirectoryAdded hook, /deep-research explicit-invocation note, /code-review background subagent, context:fork background default, agent frontmatter hook workspace trust, dynamic workflow size guideline and workflowSizeGuideline key, sandbox.network.strictAllowlist, MCP error surfacing, stream-json nested subagent forwarding, frontmatter boolean values, agent name ':' rejection, auto/plan-mode classifier changes, and Opus 5 safety-classifier fallback. Renamed the deep-research skill example to topic-research to stop it shadowing the built-in; mirrored to vi/ja/uk. doc-generator rename mirrored to ja/zh/uk.
