Additive sync over v2.1.176 baseline. No breaking changes, removals, or
deprecations in the v2.1.177-v2.1.179 window (v2.1.177 is a chore-only
release; v2.1.179 is bugfix-only plus a plugin perf note).
New in v2.1.178:
- 10-cli: document generalized Tool(param:value) parameter-matching
permission syntax (cites permissions reference for per-tool examples)
- 03-skills: nested .claude/skills/ collision rule (closest to cwd wins)
- 04-subagents: nested .claude/ precedence for agents/workflows/output-styles
- /doctor flat-tree layout refresh (10-cli, 01-slash-commands)
- /bug now requires a description before submit (01-slash-commands)
New in v2.1.179:
- 07-plugins: improved plugin loading performance in remote sessions
Footers on all five edited files bumped to v2.1.179 / June 17, 2026.
* docs: sync to Claude Code v2.1.176
Fix the subagent-nesting self-contradiction in 04-subagents and document
additive features shipped in v2.1.172-v2.1.176:
- 04-subagents: subagents can now spawn subagents (up to 5 levels, v2.1.172),
replacing the stale "no nested spawning" line; footer bumped to 2.1.176
- 07-plugins: /plugin marketplace search bar (v2.1.172)
- 10-cli: new settings.json keys wheelScrollAccelerationEnabled,
footerLinksRegexes, language (v2.1.174-v2.1.176)
- 09-advanced-features: enforceAvailableModels managed setting (v2.1.175)
- 06-hooks: if-condition tool-argument path matchers (verified against the
official permissions reference)
- claude_concepts_guide & CATALOG: subagent nesting note + VSCode /usage
attribution breakdown (v2.1.174)
* fix(10-cli): correct language setting scope and fix link-checker false positive
- check_links.py: skip bare-hostname captures (no dot in host) that URL_RE
truncates from regex strings in JSON config examples, e.g.
"https://jira\\.example\\.com/.*" was captured as "https://jira" and
flagged as a dead link in CI strict mode. Dotted hosts (real URLs) and
SKIP_DOMAINS single-label hosts are unaffected, so no link coverage is lost.
- 10-cli/README.md: language is Claude's general response/voice-dictation
language setting (e.g. french/japanese), which v2.1.176 also wired to
session-title generation — not a session-titles-only key. Updated the
description and the JSON example value to match the official settings docs.
* chore(idd): exempt docs-sync PRs from traceability Closes #N requirement
Adds .gitissue.yml so 'docs: sync to Claude Code vX' PRs (which aren't tied to
a single tracked issue) are not hard-blocked on a missing Closes #N — they opt
in via a 'Type: docs' body line, matching how chore/refactor PRs work. The
other three traceability checks still run.
- 10-cli/README.md: policy → local → project → user (was project → local → policy → user)
- 02-memory/README.md: reorder table levels 3/4/5 to local → project → user
- 02-memory/README.md: update note text to match corrected order
* docs: sync to Claude Code v2.1.156 and Claude Opus 4.8
Model bump Opus 4.7 -> Opus 4.8 and version sync v2.1.150 -> v2.1.156.
- Rewrite effort-ladder claims for Opus 4.8 (default `high`; `xhigh` on
4.8/4.7; `max` on 4.8/4.7/4.6 and Sonnet 4.6; Haiku has no effort).
- Replace soon-removed CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE with the
`/model claude-opus-4-6[1m]` + `/fast on` path; note Opus 4.8 fast mode.
- Bump lineup tables to Opus 4.8; fix Haiku 4.5 context (1M -> 200K).
- Sweep Compatible Models + version/date footers to 2.1.156 / May 29, 2026
across 23 English docs (incl. 2.1.138/2.1.145 stragglers).
- Re-document `/simplify` as a distinct cleanup-only command (v2.1.154).
- Add Dynamic Workflows + `/workflows`, MessageDisplay hook (count 29->30),
disallowed-tools frontmatter, `/reload-skills` + SessionStart outputs,
`/model` default-save inversion, lean system prompt, status-line
COLUMNS/LINES, and the ultracode `/effort` note.
* docs(cli): drop unverified fast-mode dollar pricing, keep verified rate/speed multipliers
Bumps tutorial coverage from v2.1.138 → v2.1.143. Highlights:
- /goal and /scroll-speed slash commands (v2.1.139)
- claude agents Agent View (Research Preview) with 9 dispatch flags
- claude plugin details and marketplace context-cost projection
- Hook exec form (args), continueOnBlock on PostToolUse, terminalSequence
- Stop hook 8-block safety cap + override env var
- Fast Mode default flipped to Opus 4.7 (v2.1.142)
- PowerShell tool default-on for Bedrock/Vertex/Foundry on Windows
- API-key auth disables Remote Control, /schedule, claude.ai MCP, notifications
- worktree.bgIsolation setting
- CLAUDE_PROJECT_DIR for MCP stdio servers
- Subagent OTEL headers + case-insensitive subagent_type matching
- Root-level SKILL.md plugin pattern; Routines marketing name note
Also bumps stale "28 hook events" counts in CATALOG/README to 29 and
refreshes the metadata footer (Last Updated, Claude Code Version,
Sources) on every modified file.
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.
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
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.

per new convention).

to accurately reflect the documented Claude Code version.
