* docs: sync to Claude Code v2.1.257
Audit against Claude Code v2.1.257 (repo baseline was v2.1.245, 12 releases
behind). Facts verified against the official docs and cross-checked against
the locally installed 2.1.257 binary.
Critical (P0):
- lesson-quiz L06 Q9 asked how many hook events exist, offering 16/25/31/40.
With the real answer now 33, no option was correct. Option C 31 -> 33;
answer letter unchanged.
- 03-skills taught SKILL.md `name`/`description` as required. Official docs
now state all frontmatter fields are optional and `name` defaults to the
directory name. Corrected in all five languages.
Hook events 31 -> 33 (PreModelSwitch/PostModelSwitch, v2.1.251) across 30
occurrences in 22 files, including three that read 25. Delta proved by
set-diff against the official event table: no phantom events. Both events
added to the 06-hooks tables with matcher, blocking behavior and 30s timeout,
plus detailed per-event sections.
CLI corrections verified against the binary:
- `claude plugin tag` takes a path, not a version
- `claude plugin init` / `validate` require their arguments
- `plugin init` scaffolds at ~/.claude/skills/<name>/, not project-local
- `--channels` entries must be tagged plugin:<name>@<marketplace>
- `--remote` is a deprecated alias for `--cloud`
- no `claude remote-control` subcommand exists, only the --remote-control flag
Also: CATALOG summary-table totals recomputed in all five languages (column 4
is a derived total, so the count change invalidated it); stale Opus 4.6/4.7
rosters aligned to canonical; self-assessment Advanced Features rescored 0-3
to stop a real gap being graded as mastery; 9 dangling quiz Review pointers
repaired; new features documented (--restricted, Fable 5.1,
experimental.cacheTtl, CLAUDE_CODE_SUBAGENT_MODEL_FORCE).
Deliberately out of scope: pre-existing translation staleness whose fix is
translation authorship rather than correction (ja/uk April-2026 root-doc
bodies, zh stubs, vi/README stub, translated CATALOG "New Features").

* fix(hooks): complete the 31 → 33 hook-event propagation across all languages
The v2.1.257 sync bumped the hook-event count in the lesson and catalog
summaries but left 14 files still asserting 31, four of which the same
commit restamped 2.1.257. It also bumped the prose count in
claude_concepts_guide.md without adding the two rows, making that file
contradict itself where it had been internally consistent before.
Adds PreModelSwitch and PostModelSwitch (v2.1.251) everywhere an
exhaustive enumeration exists, and corrects the count wherever a list is
deliberately partial:
- README.md / INDEX.md in en, ja, zh, uk and vi/INDEX.md — count 31 → 33
and both events added to the lifecycle group
- resources.md in all five languages — count only; these lists end in
"and more" and are partial by design
- claude_concepts_guide.md — the two missing table rows
Also brings every hook-event table up to the 33 its own summary row
claims. The English CATALOG.md listed 29; the translated catalogs listed
25 and the ja/uk concept guides 27 and 28. Completing them required
translating six events that had never reached the mirrors: Setup,
UserPromptExpansion, PermissionDenied, PostToolBatch, MessageDisplay and
DirectoryAdded.
Summary-table arithmetic is untouched — those columns count example
scripts, not events.
Verified: no stale count survives outside CHANGELOG history, every
exhaustive enumeration lists exactly 33, and pre-commit passes 23/23.

* docs: sync to Claude Code v2.1.233
Bring the tutorial from the v2.1.220 baseline up to v2.1.233 (13 releases)
per update-plan-2026-08-15.md.
Corrections:
- Remove /ultraplan (removed in v2.1.222); point at plan mode instead
- Drop the 200-subagent-per-session cap and CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION
(cap removed in v2.1.224)
- Note TaskCompleted/TaskCreated only fire when todo tools are enabled
Updates:
- /review documented as an alias of /code-review (v2.1.223)
- fork subagents default to interactive (v2.1.232)
- ultrareview v2.1.227 floor, --post/--no-post
- GitLab MR support for -w/--worktree and Agent View
New sections:
- Cross-session messaging (ListAgents, SendMessage, crossSessionInbound)
- Sandbox credential masking (v2.1.221, v2.1.224)
- Trust and permission scoping
- archive and command plugin sources, conditional plugin activation
- claude self-hosted-runner, 7 new env vars
Translations (vi/ja/zh/uk) mirrored where the corresponding pages exist.
Every modified file carries the 2.1.233 metadata footer; files already at
2.1.220 with no content change were left alone.
* docs: address review findings from the v2.1.233 sync
- Mirror the /review alias correction (v2.1.223) into vi/ja/uk/zh
01-slash-commands: add the live alias row, drop the stale row from the
deprecated table, and rewrite the history bullet. All four still called
/review deprecated in favour of a code-review plugin while carrying a
2.1.233 stamp.
- Rewrite the 10-cli CLAUDE_CODE_FORK_SUBAGENT row to agree with
04-subagents: fork mode is on by default in interactive sessions on every
build since v2.1.232; the variable enables it where it is off by default.
- Remove a stray blank line that split the 10-cli environment-variable
table, leaving the seven new v2.1.221-v2.1.233 rows without a delimiter
row and rendering them as literal pipe text.
- Add the todo-tools caveat to the TaskCompleted row alongside TaskCreated
in claude_concepts_guide, uk/ja concepts guides, and the uk/vi/zh/ja
CATALOGs.
- Fix the ja 07-plugins and 09-advanced-features footers, which paired a
2.1.233 version stamp with an April 24 last-updated date.
* docs(subagents): correct the stale fork-subagent claim in ja pages (#171)
ja/10-cli and ja/04-subagents both stated that CLAUDE_CODE_FORK_SUBAGENT
only enables forked subagents on external builds (Bedrock, Vertex,
Foundry) with no effect on the Anthropic API. That was true at v2.1.117
but has been wrong since v2.1.232: fork mode is on by default in
interactive sessions on every build, first-party or not, and the variable
now turns it on where it is off by default (claude -p, the Agent SDK, or
Claude Code older than v2.1.232).
Both pages remain stamped 2.1.119 on purpose. Only the individual claim
was verified and corrected; bumping the page stamp would assert a
whole-page verification that has not been done. Do not bump these stamps
without a full resync of the pages.
Bumps tutorial coverage from the v2.1.212 baseline (2026-07-18 sync) to
v2.1.217 (v2.1.213 was skipped upstream), plus a repo-internal accuracy
audit.
Fixed:
- Nested-subagent-spawning claim reversed (v2.1.217): 04-subagents/README.md
and CATALOG.md stated nesting up to 5 levels as current behavior; as of
v2.1.217 it's off by default, opt in via CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH
- Stale --enable-auto-mode flag (removed in v2.1.111) replaced with
--permission-mode auto across 10-cli/README.md and QUICK_REFERENCE.md
- Import-depth contradiction in 02-memory/README.md: two remaining "5 levels"
instances corrected to "4 hops", matching the rest of the file
- Sonnet 5 added to claude_concepts_guide.md's models/reasoning-effort table
- config-examples.json's fabricated settings schema (fake "unrestricted"/
"confirm" modes, undocumented keys) rewritten to real settings.json keys
- brand-voice skill (name/user-invocable) aligned to its README worked example
- CLAUDE.md length guidance unified across 03-skills/claude-md/SKILL.md and
02-memory/README.md
Added:
- New subagent caps (v2.1.217): CLAUDE_CODE_MAX_CONCURRENT_SUBAGENTS
- --max-budget-usd now also halts running background subagents (v2.1.217)
- Hook if: glob scope narrowed to <cwd>/dir (v2.1.214), documented in
06-hooks/README.md along with SessionStart's new "fork" source
- sandbox.filesystem.disabled setting (v2.1.216)
- /rewind symlink/hard-link protection (v2.1.216)
- Auto-memory modified timestamp (v2.1.214) and non-blocking /memory editor
(v2.1.216)
- CLI/settings batch (v2.1.214-217): emojiCompletionEnabled,
FORCE_HYPERLINK=0, CLAUDE_CODE_OTEL_CONTENT_MAX_LENGTH, --settings 2 MiB
cap, permission hardening notes, /context and /compact notes
- /verify and /code-review explicit-invocation-only note (v2.1.215)
Mirrored applicable P0/P1 fixes into vi/ja/zh/uk translations where the
same claim existed.
Mirror the English fix from #131 into the translated docs. The precedence
table in 02-memory and the v2.1.119 /config notes still encoded the old,
incorrect order (user above project/local).
- vi/02-memory: table rows -> local(3) -> project(4) -> user(5, lowest)
- ja/02-memory: table rows reordered + /config note policy/local/project
- ja/10-cli: /config note chain -> policy -> local -> project -> user
- uk/02-memory: table rows reordered
Correct order per https://code.claude.com/docs/en/settings:
Managed -> CLI args -> Local -> Project -> User (lowest).
zh is missing the whole settings section (structural port), tracked
separately in #132.
