New Features & Practical Usage

Claude Security Public Beta — Enterprise Codebase Vulnerability Scanning (4/30)

Anthropic launched Claude Security in public beta, graduating from its February research preview (Claude Code Security) to a full product. It’s available to all Claude Enterprise customers now, with Team and Max support coming soon.

Powered by Claude Opus 4.7, Claude Security goes beyond static analysis to reason about code like a human security researcher. It traces data flows across files and modules, understands component interactions, and flags context-dependent vulnerabilities that rule-based tools miss. Each finding includes confidence ratings, severity assessments, reproduction steps, and patch suggestions.

Key capabilities:

Technology partners: CrowdStrike, Microsoft Security, Palo Alto Networks, SentinelOne, TrendAI, and Wiz are embedding Opus 4.7 into their products. Services partners: Accenture, BCG, Deloitte, Infosys, and PwC are helping organizations deploy Claude-integrated security solutions.

# Access Claude Security (Enterprise customers)
# Via claude.ai sidebar or claude.ai/security
# No API integration or custom agent build required

Nothing is applied without human approval — Claude Security follows a strict HITL (Human-in-the-Loop) design.

Developer Workflow Tips

Make Plan Mode Your Default — Always Plan Before Complex Tasks

A consistent pattern across the Claude Code community after a year of adoption: always start with Plan mode for anything beyond trivial tasks. Having Claude design its approach before writing code lets you catch wrong assumptions before implementation begins. Correcting a plan is always easier than unwinding a half-finished feature.

# Starting complex work with planning
claude "Before implementing this feature, create a plan first.
Outline the approach, files to modify, and potential risks."

# Or use Shift+Tab to toggle Plan mode before starting

This principle is reinforced across Anthropic’s official docs, Marmelab’s field guide, and multiple community best-practice compilations.

Warm Up Sessions with Codebase Questions

Instead of jumping straight into implementation, start new sessions by asking Claude simple questions about the codebase. Claude explores file structures, git history, and component relationships, building accurate context before execution. It’s a fast way to understand unfamiliar code without asking teammates.

# Session warm-up examples
claude "Explain the auth flow in this project. Include which middleware is involved."
claude "What files have changed the most in the last week?"

Security & Limitations

Claude Code Refuses Requests When Commits Mention “OpenClaw” (4/30)

Claude Code has been reported to refuse requests or trigger extra billing when commit messages contain OpenClaw-related strings. Even in an empty repository, adding openclaw.inbound_meta.v1 to a commit message causes usage-related errors.

This follows a similar pattern to the earlier HERMES.md incident, suggesting an anti-abuse system detecting strings in git logs rather than direct command inputs. Anthropic blocked subscription-based OAuth tokens from third-party tools including OpenClaw in early April, and this detection appears to be part of that enforcement.

The developer community has criticized this as overreach: “The moment your toolchain starts punishing you for mentioning a competitor’s name in a JSON blob, you’ve lost the plot.”

White House Opposes Anthropic’s Mythos Access Expansion (4/30)

The Trump administration has told Anthropic it opposes the company’s plan to grant Mythos access to approximately 70 companies and organizations. This escalates the government-level tension around Mythos from Pentagon supply-chain risk designation and UK government discussions to the White House level.

Access beyond the existing Project Glasswing partners (AWS, Apple, Google, JPMorgan, Microsoft, Nvidia) now appears increasingly unlikely.

Claude Pro Plan A/B Test Removes Claude Code Access (4/22)

Anthropic ran an A/B test removing Claude Code access from approximately 2% of new Pro ($20/month) subscribers. The pricing page briefly changed the Claude Code checkmark to an “X,” triggering immediate community backlash.

Anthropic’s growth team explained that subscription usage patterns have “fundamentally changed” since Max launched, with long-running async agents becoming everyday workflows. The test was quickly reversed, but it signals that the $20/month price point for AI coding agents may not be sustainable long-term.
