* 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.
* docs: sync to Claude Code v2.1.212
Bumps tutorial coverage from the v2.1.206 baseline (2026-07-11 sync) to
v2.1.212, plus a repo-internal accuracy audit that surfaced defects
independent of the version delta.
Fixed:
- Dead `#` memory-shortcut removed from 02-memory/README.md (two places
documented a discontinued quick-memory-add pattern as working, directly
contradicting the file's own commands table)
- Auto mode opt-in -> opt-out on Bedrock/Vertex/Foundry (v2.1.207)
- `auto` permission mode mislabeled "Research Preview" across
09-advanced-features/README.md, CATALOG.md, README.md, and the vi/ja/zh/uk
translations (auto mode is GA, gated only by plan/model/provider)
- `/fork` / `/branch` history corrected: they were a single aliased command
only from v2.1.77 to v2.1.161, not "renamed" as previously stated
- `effort` frontmatter enum in 04-subagents/README.md completed with `xhigh`
- Bundled-skills count reconciled in CATALOG.md (9 -> 10)
- INDEX.md Skills section count and Feature Coverage Matrix Total column
fully recomputed and reconciled (Skills: 22, Plugins: 39)
- Stale 2.1.160 footer cluster (5 files) bumped to 2.1.212
- QUICK_REFERENCE.md fully resynced (was 52 versions behind)
- 02-memory/README.md's Memory Hierarchy section rewritten: replaced a
fabricated 8-tier strict-precedence model with the verified structure
(CLAUDE.md files are concatenated into context, not overridden; 4 real
location tiers; rules and auto memory are separate mechanisms)
- 02-memory/README.md's Memory Architecture diagram no longer conflates
claude.ai's 24h synthesis cycle with Claude Code's continuous auto memory
- Import recursion depth corrected (was documented as 5, actually 4 hops)
Added:
- Subagent output scanning (v2.1.210) documented in 04-subagents/README.md
- Session-wide spawn caps (v2.1.212): WebSearch and subagent limits
- MCP long-running-tool auto-backgrounding (v2.1.212) in 05-mcp/README.md
- `claude auto-mode reset` and `/resume` picker (v2.1.212)
- Screen reader mode (v2.1.208): --ax-screen-reader / CLAUDE_AX_SCREEN_READER
- Task tool `mode` parameter deprecation note (v2.1.212)
Known gaps (deferred, not fixed this pass):
- 03-skills/blog-draft/ vs 03-skills/.claude/skills/blog-draft/: confirmed
the latter is gitignored local testing scratch, not a repo duplicate
* fix(INDEX): correct Skills row arithmetic and stale changelog notes
INDEX.md's Skills header/matrix shipped as 22 (5+9+8) despite the PR's
own CHANGELOG claiming it was fixed to 21 — three independent counts
(file-type breakdown, filesystem listing, changelog intent) agree on
21; the Docs column was off by one. Also removes two stale CHANGELOG
"Known gaps" entries this same PR already resolved (memory hierarchy
rewrite, blog-draft gitignore confirmation) and adds the missing
Fixed-section bullet documenting the memory hierarchy rewrite.
- Replace fictional `/think` example with official `ultrathink` keyword
- Fix Q4 options: `/think` → `/effort max`, `--thinking` → `ultrathink`
- Fix Q5: correct the answer that "ultrathink" DOES trigger deep reasoning
- Sync changes across English, Ukrainian, and Vietnamese translations
Background: `/think` is not a valid slash command in Claude Code (verified
against official commands reference at code.claude.com/docs/en/commands).
The correct way to trigger deep reasoning for a single response is to
include "ultrathink" in the prompt.
Sources:
- https://code.claude.com/docs/en/commands (no /think command exists)
- https://code.claude.com/docs/en/model-config (ultrathink is valid keyword)

Modules 06-hooks, 07-plugins, 09-advanced-features, 10-cli had
truncated translations (18-58% content loss). Retranslated from
scratch using original English sources.
All files now match expected ~40% size increase for Cyrillic.
