* 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.
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.
