New Features & Practical Usage

OpenClaw-Style Claude CLI Usage Permitted Again

Anthropic has officially confirmed that OpenClaw-style Claude CLI usage is permitted again, supporting both Anthropic API keys and Claude CLI reuse. OpenClaw is an LLM-based agent that runs locally with shell and filesystem access.

This clarification resolves previous policy ambiguity around third-party agent frameworks leveraging the Claude CLI, putting these integrations on stable footing.

Developer Workflow Tips

The 60% Context Threshold Rule — /clear Beats /compact

Multiple practitioners have independently converged on the same conclusion: keep context usage below 60%. Auto-compaction fires at roughly 83.5% and is lossy, retaining only about 20–30% of details.

The pattern:

1. Save your current plan and progress to a markdown file
2. Run /clear to fully reset context
3. Start fresh with Claude reading that file

This approach outperforms /compact because you control exactly what survives into the next session.

# Save progress to markdown, then reset
claude "Save current plan and progress to progress.md"
/clear
claude "Read progress.md and continue from where we left off"

Medium - Effective Claude Code Workflows

The 4-Phase Workflow — Research → Plan → Implement → Validate

This is the most widely adopted pattern as of April 2026. The key insight: clear context between each phase rather than running everything in a single session.

The planning process specifically:

1. Ask Claude to “draft a plan with no implementation yet”
2. Open the plan in your editor and annotate where Claude got it wrong
3. Send it back: “address all notes, don’t implement yet”
4. Only then authorize implementation

This aligns with Anthropic’s internal testing showing that skipping the planning step yields only ~33% success rates.

Security & Limitations

Pro Plan Claude Code Access Removal — A/B Test Controversy (4/22)

Anthropic ran an A/B test that removed Claude Code access from new Claude Pro ($20/month) subscribers, sparking significant backlash. Support docs changed from “Pro or Max” to just “Max,” and pricing pages were updated globally.

Timeline:

• Anthropic’s head of growth Amol Avasare: “a small test on ~2% of new prosumer signups”
• Existing Pro/Max subscribers unaffected
• However, public pricing pages and support docs were changed globally, not just for the 2% test group
• Changes were subsequently rolled back

Context: Subscription fees are sometimes a fraction (as low as 1/10) of the actual token cost, creating financial pressure to restructure plans. Simon Willison called it “all very confusing.”

Mythos Model Unauthorized Access — Via Third-Party Contractor (4/21)

Anthropic’s cybersecurity-focused Claude Mythos Preview was accessed by an unauthorized group, as first reported by Bloomberg.

How it happened:

• A private Discord group gained access on the same day Mythos was announced
• They guessed the model’s URL by analyzing Anthropic’s URL patterns for other models
• One employee at a third-party contractor was involved in providing access
• The group’s stated interest was “playing around with new models, not wreaking havoc”

Anthropic’s response: Investigating the claims, maintaining no evidence their systems were impacted. The activity reportedly did not extend beyond the third-party vendor environment.

The fact that a model Bloomberg described as “too dangerous to release” was informally accessed on its announcement day raises questions about the security of limited-preview distribution models.

Anthropic Posts Record Lobbying Spend — $1.6M in Q1 2026 (4/21)

Federal lobbying disclosures show Anthropic spent $1.6M in Q1 2026 — a ~4.4x increase from $360K in Q1 2025 and its largest quarter ever.

Lobbying topics: AI procurement, Defense Department procurement, supply chain risk, acceptable use policy (the core of the Pentagon dispute), AI and national security, export controls, energy infrastructure.

For comparison: OpenAI spent $1M (also a record), Meta led Big Tech at $7.1M, Amazon $4.4M, Google $2.9M. AI companies are scaling their Washington presence at an unprecedented rate.
