Documents the v2.1.131 → v2.1.138 sync (PR #117) in the same format
as the v2.1.131 entry. Pattern caught during release-manager review;
the original sync PR did not include a CHANGELOG update.
Sync covers v2.1.128, v2.1.129, and v2.1.131 (May 2026). Highlights:
gateway /v1/models discovery is now opt-in (CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY),
added --plugin-url flag, disableRemoteControl setting, /mcp tool-count display,
expanded skillOverrides values, /context viz no longer leaks into conversation,
Ctrl+R cross-project default. Also reconciles slash-command count to 60+ and
fixes the skill-count entry in CATALOG.
The lesson-quiz skill had two issues:
1. Correct answers were always placed as the first option, making quizzes
trivially solvable
2. No feedback was given after each round — users had to wait until all
5 rounds were complete to see any results
Add a CRITICAL shuffle instruction requiring randomized option order for
each question, and update round flow to show immediate per-question
feedback after each round.

The code-review skill had templates/ and scripts/ directories alongside
SKILL.md, but SKILL.md never referenced them. Since Claude Code only
loads SKILL.md when a skill is invoked, the supporting files were
effectively invisible. This adds a Reference Files section that
instructs Claude to read and use each supporting file.
Closes#43

- 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)

The lesson quiz Q2 had `#` prefix as the correct answer for adding
memory rules, but the lesson README explicitly states this was
discontinued. Update answer to `/memory` or conversational request,
and fix a residual `#` prefix reference in the README's "Quick
update workflow" section.

Remove the specific 21,800+ stars and 2,585+ forks numbers across en/zh/ja
READMEs. They go stale within a day of every commit. The Star History chart
already conveys current scale, and the trust bullets read fine without exact
counts.
- Backfill CHANGELOG.md with v2.4.0 entry summarizing the
v2.1.112 → v2.1.119 sync work
- Refresh SECURITY.md footer (Last Updated April 27, 2026;
Next Review April 2027)
- Fix model ID in 09-advanced-features/config-examples.json:
claude-opus-4 → claude-opus-4-7 (3 occurrences) for
consistency with documented model IDs
- Remove RELEASE_NOTES.md stub that duplicated and contradicted
CHANGELOG.md
Closes#99
- Replace shell-interpolated JSON build with the argv-based Python pattern
from session-end.sh, so notes containing quotes or backslashes don't
produce invalid JSON.
- Add mkdir/cp/chmod install block before the Configuration section so
the path in settings.json resolves to a real file.
Lesson 10 stated CLI > User > Project, contradicting Lesson 04 (CLI >
Project > User) and the official Claude Code docs. Project-level agents
override user-level agents when their names collide.
- Fix priority order in 10-cli/README.md (lines 437-439)
- Add cross-link to Lesson 04 for the full priority table
- Update matching quiz question Q7 in lesson-quiz question-bank
Closes#98
* feat(hooks): add SessionEnd progress logger and local progress tracker
Adds a SessionEnd hook that prompts for modules studied at session end
and appends a record to ~/.claude-howto-progress.json — outside the repo
so progress survives git pull without being overwritten.
Also adds local-progress/index.html: a self-contained visual tracker
with checkboxes for all 10 modules, per-module notes, an overall progress
bar, and Export/Import to sync with a local JSON backup file.
Key patterns demonstrated:
- SessionEnd vs Stop (fires once on exit, not after every response)
- /dev/tty for interactive input in hooks (stdin carries the JSON payload)
- $CLAUDE_PROJECT_DIR for portable paths (never hardcode /Users/...)
- Guard clause to prevent global hook running in unrelated projects

* fix(hooks): address PR review — bash 3.2 compat, JSON escaping, textarea XSS
- Replace pipeline+while with IFS for-loop (bash 3.2 compatible)
- Pass NOTES as Python arg to avoid broken JSON on quotes/backslashes
- Set textarea.value instead of innerHTML to prevent XSS from imported JSON

Per official docs (https://code.claude.com/docs/en/model-config#adjust-effort-level),
the `max` effort level is supported on Opus 4.7, Opus 4.6, and Sonnet 4.6 — not
Opus 4.7 only. Only `xhigh` is Opus 4.7 exclusive.
Updates 5 occurrences in 09-advanced-features/README.md to reflect the actual
support matrix:
- Opus 4.7: low, medium, high, xhigh, max
- Opus 4.6 / Sonnet 4.6: low, medium, high, max
uk/ and vi/ locales need a separate translation sync (still reference Opus 4.6
era only and lack xhigh entirely).
Split the "Skill" participant into two distinct entities to better
illustrate the three-level loading architecture:
- Skill Instructions (Level 2): SKILL.md body
- Skill Resources (Level 3): Bundled files (templates, scripts, etc.)
Also fixed inaccurate "bash: read" notation - Claude uses the Read
tool, not bash commands.

* test(scripts): cover repo-root boundary in check_cross_references
Locks in the boundary behavior added in #91: links resolving outside
the repo root are silently skipped, in-repo broken links still error,
and valid in-repo links still pass.
* test(scripts): cover missing-README detection in numbered lesson dirs
`(file_path.parent / link_path).resolve()` could silently follow a
crafted `../../outside/path` link that escapes the repository root.
Paths that resolve outside the repo root are now skipped rather than
checked for existence.

All 6 packages were fully unpinned, allowing a compromised upstream
release to silently introduce malicious code on `pip install`. Pin to
current stable versions to ensure reproducible, auditable builds.

`diff` is not a valid Claude Code tool name — the agent would silently
lose its diff capability at runtime. Use `bash` to invoke diff instead.

Sync all English tutorials with Claude Code v2.1.112 and the new Opus 4.7
model (claude-opus-4-7). Introduces the xhigh effort level (new default on
Opus 4.7), two new built-in slash commands (/ultrareview,
/less-permission-prompts), auto mode without --enable-auto-mode for Max
subscribers on Opus 4.7, PowerShell tool on Windows, Auto-match-terminal
theme, and plan files named after prompts. All 18 EN doc footers bumped to
Claude Code v2.1.112.
Version callouts in README.md, zh/README.md, and uk/README.md updated to
v2.1.112. Changelog entry prepended.
Repo version now tracks Claude Code version (2.3.0 → 2.1.112 is intentional
per new convention).
* docs: sync to Claude Code v2.1.110 with TUI, push notifications, session recap, and new commands
- 01-slash-commands: add /tui, /focus, /recap, /undo, /proactive to command table and recent changes
- 07-plugins: document monitors manifest key for background monitor support (v2.1.105)
- 09-advanced-features: add TUI mode, push notifications, session recap, ENABLE_PROMPT_CACHING_1H
- 10-cli: add --exclude-dynamic-system-prompt-sections flag and CLAUDE_CODE_PERFORCE_MODE env var
- CATALOG.md: update command counts (55+→60+, 63+→68+), add 5 new command rows
- All 12 files: bump footer to April 16, 2026 / Claude Code Version 2.1.110
* fix(catalog): correct version tags for /proactive, /recap, /undo commands
/proactive was added in v2.1.105, /recap and /undo in v2.1.108 — not v2.1.110.
Only /tui and /focus were introduced in v2.1.110.
The pre-tool-check.sh example had three bugs rooted in the same
misunderstanding of the Claude Code PreToolUse hook protocol
(stdin/stdout/stderr + exit code contract):
1. Substring matching on `rm -rf /`
The pattern was unanchored, so grep treated it as a substring and
falsely blocked any command containing `rm -rf /` — including benign
calls like `rm -rf /tmp/build` or `rm -rf /var/cache/foo`. Fixed by
anchoring the slash to a whitespace-or-end-of-line boundary.
2. WARN tier was dead code
The warning layer printed to stderr and then `exit 0`. Claude Code
silently discards stderr on exit 0, so the warnings were never seen
by Claude, the user, or any log. Fixed by adding an audit log file
at `$CLAUDE_PROJECT_DIR/.claude/hooks/audit.log` that records every
invocation with its decision (BLOCK/WARN/ALLOW). The audit log is
now the reliable observability mechanism for the WARN tier.
3. BLOCK reasons printed to stdout instead of stderr
On `exit 2`, Claude Code reads stderr to surface the block reason
to Claude. The echoes before `exit 2` defaulted to stdout, so
Claude Code reported `"No stderr output"` and Claude had to read
the hook source file to infer why a command was blocked. Fixed by
explicitly redirecting the block-reason echoes to stderr with `>&2`.
Also escaped the regex metacharacters in the fork-bomb pattern
`:(){:|:&};:` so it matches literally under `grep -E`, and updated the
header docstring to document the stdout/stderr/exit-code convention so
future readers don't make the same mistakes.
Verified with 6 smoke tests covering: benign command (ALLOW), warn-tier
relative path, substring edge case (`rm -rf /tmp/...` no longer falsely
blocked), exact root match (`rm -rf /`, `rm -rf / ; echo` still blocked),
fork-bomb literal, and `git push --force` (WARN only). stdout is empty
in all cases; all reasons correctly routed to stderr or the audit log.
