New Features & Practical Usage

v2.1.119 — Persistent Config, Multi-Platform PR Review, Hook Timing (4/23)

Released shortly after v2.1.118, v2.1.119 brings several practical improvements.

Persistent /config Settings: Settings changed via /config now persist to ~/.claude/settings.json with project/local/policy override precedence. Your preferences survive across sessions.

prUrlTemplate — Custom Code Review URLs: Teams using custom code review systems can now configure PR URL templates to match their infrastructure.

--from-pr Multi-Platform Support: Beyond GitHub, --from-pr now accepts GitLab, Bitbucket, and GitHub Enterprise PR URLs. This enables PR-based code review workflows across all major Git platforms.

Hook duration_ms: PostToolUse and PostToolUseFailure hooks now include tool execution time (duration_ms). Useful for tracking performance bottlenecks or detecting slow tools.

# Start a code review from a GitLab MR
claude --from-pr https://gitlab.com/org/repo/-/merge_requests/42

# Bitbucket PRs also supported
claude --from-pr https://bitbucket.org/org/repo/pull-requests/15

# Hook responses now include duration_ms
# for performance tracking in PostToolUse hooks

Other improvements: PowerShell tool commands can be auto-approved, --print mode honors agent tools:/disallowedTools: frontmatter, Vim Esc in INSERT no longer pulls queued messages, new CLAUDE_CODE_HIDE_CWD environment variable.

Developer Workflow Tips

Context Quality Beats Effort Level — The 80% Heuristic

When you find yourself reaching for Max effort on seemingly simple tasks, 80% of the time the actual problem is upstream context gaps, not insufficient model thinking. Analysis from BSWEN shows that “a model on Low with great context often outperforms the same model on Max with poor context.”

Before increasing effort, audit your CLAUDE.md for:

  1. Commands — Copy-paste-ready build and test syntax
  2. Architecture — Directory structure and module relationships
  3. Patterns — Key conventions with concrete examples
  4. Gotchas — Non-obvious project quirks
  5. Currency — All references still accurate

When effort budget is spent reconstructing project state instead of solving your actual problem, raising the effort level just wastes more tokens on reconstruction. Fix context first.

The Over-Editing Problem in AI Code Generation — Claude Opus 4.6 Leads

When asked to fix a simple bug, AI models often restructure entire functions, rename variables, and add helper functions — creating massive diffs that obscure the actual fix. This “over-editing” makes code review harder while remaining invisible to test suites.

Research shows Claude Opus 4.6 had the lowest over-editing among tested models (normalized edit distance 0.060), while GPT-5.4 scored 0.395 — over 6x more unnecessary changes.

Practical fix: Adding explicit instructions like “preserve the original code structure and logic as much as possible” significantly reduced over-editing across all models.

# Add to CLAUDE.md for minimal-diff bug fixes:
# "When fixing bugs, preserve original code structure and logic.
#  Do not rename, refactor, or add helper functions unnecessarily."

Security & Limitations

Mythos Rattles Washington — Treasury Secretary Convenes Emergency Banking Meeting (4/24)

The Washington Post reports that Anthropic’s Mythos model is causing significant concern in Washington. Treasury Secretary Scott Bessent convened a meeting of senior American banking executives in April to discuss risks and potential uses of the Mythos model.

The meeting encouraged banks to use Mythos to detect vulnerabilities in their own systems. Simultaneously, the Trump administration is assessing the risks of Mythos’s ability to rapidly discover and exploit software vulnerabilities.

Combined with the unauthorized Mythos access incident (4/21), the Pentagon dispute, and NSA’s continued Mythos usage, policy tensions around AI cybersecurity models are intensifying.

Google Invests Up to $40B in Anthropic — $10B Immediate, Rest Milestone-Linked (4/24)

Google (Alphabet) announced an investment of up to $40B in Anthropic. $10B is committed immediately at a $350B valuation, with the remaining $30B tied to performance milestones.

Google Cloud will deliver 5GW of computing power to Anthropic over five years, with room for further expansion.

Within a single week, Amazon ($25B) and Google ($40B) have committed a combined $65B to Anthropic. Both tech giants investing simultaneously at this scale marks a new phase in the AI infrastructure race.

Context: Anthropic’s annualized revenue surpassed $30B in April, up ~233% from ~$9B at end of 2025.
