* docs: sync to Claude Code v2.1.235
Syncs the tutorial repo from v2.1.233 to v2.1.235, fixes a fabricated
plugin-command reference and a wrong lesson-quiz answer, closes translation
fan-out gaps, and documents six new features from v2.1.234/v2.1.235.
* docs(slash-commands): scope v2.1.234 dialog-command claims to the fullscreen TUI
The v2.1.234 changelog carries two separate entries: /permissions opening
mid-turn unconditionally, and the /add-dir, /autocompact, /theme, /help,
/config and /advisor dialogs opening mid-turn in the fullscreen TUI. The
sync flattened both into one unqualified bullet, so a reader on the default
renderer would find the described behavior absent.
Also corrects the CATALOG usage-limit auto-continue row, which described an
on-by-default feature as opt-in ("Enable via /config"); the changelog says
"turn it off in /config".
* docs(advanced-features): correct spellcheck value shape, default, and scope
settings.md documents `spellcheck` as object-valued
(`{"enabled": true, "language": "en_GB"}`) and read from user settings, the
--settings flag, and managed settings only; interactive-mode.md adds that it
is off by default and needs aspell, hunspell, or ispell on PATH. CATALOG told
readers to set a bare `"spellcheck": true`, and both settings tables sit under
preambles promising project-scope settings work, which for this key they do
not.
Also repoints CATALOG's hook-configuration example at pre-tool-check.sh; the
table rename left the example on validate-bash.py, which is not in 06-hooks/.
* docs(plugins): drop the unsupported claim that /plugin update does not exist
The sync asserted "Updating is CLI-only — there is no `/plugin update` slash
command". The plugins reference contradicts that: it refers to running
`/plugin update` twice in present tense (the cache-key section, and the
explicit-version row that says `/plugin update` reports "already at the
latest version"). The v2.1.235 binary carries no `/plugin update` string and
its own update notices point at `claude plugin update <name>` in a terminal,
so the sources conflict and neither absolute is safe to teach.
Recommends the CLI form on its documented merits instead of asserting a
negative. Mirrored to vi/ja/zh/uk and to the lesson-quiz Q8 explanation,
which taught the same false negative. Q8's correct answer is unchanged.
* docs(advanced-features): complete the v2.1.234 env-var fan-out and 04 TOC (#175)
The env-var block was still headed (v2.1.221-v2.1.233) and omitted both
variables v2.1.234 added: CLAUDE_CODE_PROJECT_DIR_NAME, which had reached
only 10-cli and CATALOG, and CLAUDE_CODE_GOAL_CHECKIN_MINUTES, which was in
prose and a CATALOG row but no env-var table.
Also adds the one missing 04-subagents TOC entry: Additional Resources was
the only H2 without one, leaving the reconciled TOC at 26 of 27 sections.
* 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.
Internal accuracy pass against v2.1.220 — no missing upstream features, but broken example code, disagreeing counts, and metadata drift.
Functional fixes: pre-commit.sh now exits 2 so it actually blocks; dependency-check.sh reads file_path from stdin JSON instead of $1; database-mcp.json uses ${DATABASE_URL}; broken fences repaired; three command templates had invalid skill names.
Factual corrections: /fork and /subtask unswapped and /subtask added; /fewer-permission-prompts; permissions.defaultMode; dontAsk/auto unreversed; 31 hook events verified name-by-name; subagent depth 3; skill precedence enterprise > project > personal; /output-style removed not deprecated; permissionDecision gained defer.
Follow-up review fixed defects the pass left behind: zh/vi headers claiming 31 events above 25-name lists, a surviving hardcoded DB credential in the MCP README examples, an unbalanced fence swallowing a metadata footer, and non-canonical tool names. All four translated CATALOG summary tables were recounted so their arithmetic holds.
Full detail in CHANGELOG.md under v2.1.220-r2.
