Anthropic’s Claude has experienced a dramatic rise in early 2026, fueled by a high-profile Pentagon dispute, a viral Super Bowl ad campaign, and a wave of new model releases. Meanwhile, ChatGPT’s market share has eroded as users migrate to Claude for its writing quality, ad-free commitment, and powerful productivity features. This report covers the key recent events and compiles a comprehensive list of tips—from prompting fundamentals to advanced agentic workflows—for getting the most out of Claude.
Anthropic Hits Back After US Military Labels It a ‘Supply Chain Risk’
Part 1: What Happened to Claude Recently

The Pentagon Dispute and Trump Ban
The most dramatic recent event involves Anthropic’s confrontation with the U.S. government. Anthropic had been providing Claude to the Pentagon’s classified networks since 2024 under a $200 million contract. However, the company drew two “red lines”: Claude would not be used for mass domestic surveillance of American citizens or for fully autonomous weapons.[1][2][3]
The Pentagon insisted it needed the flexibility to deploy Claude for “all lawful purposes,” even though it stated it had no current plans to use AI for those specific applications. When Anthropic refused to relax its safeguards by the Pentagon’s deadline, Defense Secretary Pete Hegseth designated the company a “supply chain risk to national security,” barring it from working with the military and its contractors.[2][3][1]
On February 28, 2026, President Trump ordered all federal agencies to immediately stop using Anthropic’s AI tools, giving them six months to phase out the technology. He called the company’s leaders “radical left” and “woke” on Truth Social. Just hours later, OpenAI announced it had signed a separate deal with the Pentagon for its own classified network deployment, claiming it had negotiated similar safeguards against surveillance and autonomous weapons.[1][2]
Anthropic has announced plans to challenge the “supply chain risk” label in court. CEO Dario Amodei stated the company “cannot in good conscience” agree to unrestricted military use.[2]
The Paradoxical Surge in Popularity
The controversy has paradoxically boosted Claude’s popularity. As of March 1, 2026, Claude rose to the #1 free app on the Apple App Store in the U.S., overtaking ChatGPT. Daily signups have broken all-time records every day during the last week of February, free users increased more than 60% since January, and paid subscribers more than doubled in 2026.[4]
The Super Bowl Ad and Ad-Free Pledge
In early February, Anthropic ran a nationally televised Super Bowl ad with the tagline “Ads are coming to AI. But not to Claude”—a direct shot at OpenAI’s decision to introduce advertising in ChatGPT. The ad mocked the idea of an AI assistant interrupting helpful advice with product placements.[5][6]
BNP Paribas analysis showed that Claude’s daily active users jumped 11% after the Super Bowl, the biggest bump among any AI company that advertised, and Claude entered the top 10 free apps on the Apple App Store. Anthropic pledged that ads in conversations “would be incompatible with what we want Claude to be: a genuinely helpful assistant for work and for deep thinking”.[7][8]
New Model Releases
Anthropic has maintained a breakneck pace of model releases:
- Claude Opus 4.6 (February 5, 2026): The flagship model excels in coding, long-running tasks, and professional-grade outputs. It is better at planning, code review, debugging, and working with extensive codebases.[9]
- Claude Sonnet 4.6 (February 17, 2026): Released just 12 days after Opus 4.6, this model became the default for both free and paid users. It improves computer use, programming, design, knowledge work, and handling of extensive datasets.[10]
- Anthropic also closed a $30 billion funding round at a $380 billion valuation—more than double its valuation from September 2025.[10]
The ChatGPT-to-Claude Migration
ChatGPT’s app market share dropped from 69.1% to 45.3% between January 2025 and January 2026 according to Apptopia data. Claude leads all AI chatbots in average time spent per daily active user at 34.7 minutes, and power-user engagement surged 377% from June to December 2025.[11]
Key reasons users cite for switching include:
- Claude’s superior writing and reasoning quality[12]
- The ad-free commitment vs. ChatGPT’s ad introduction[7]
- Claude’s Artifacts, Skills, and Projects features[13]
- Better MCP (Model Context Protocol) integration for tool connectivity[12]
- More natural, less robotic outputs[11]
Claude Cowork Launch
In January 2026, Anthropic launched Claude Cowork, described as “Claude Code without the code”. Cowork lets users point Claude at a folder on their computer, and it autonomously organizes and executes tasks—reading, modifying, and generating files—while keeping the user informed. It integrates with connectors like Asana and Notion and features built-in Skills for document and presentation creation.[14][15]
Part 2: Tips for Using Claude More Productively
Prompting Fundamentals
These foundational techniques from Anthropic’s own documentation apply to all Claude interactions:
- Be explicit and direct: Lead with action verbs (“Write,” “Analyze,” “Create”). State exactly what the output should include, not just what to work on.[16]
- Provide context and motivation: Explain why you need something and how the output will be used. Claude generalizes better when it understands the reasoning behind instructions.[16]
- Be specific about constraints: Include word count, format, tone, audience, timeline, and any restrictions in your prompt.[16]
- Use examples (few-shot prompting): Provide 1–3 examples of desired input/output format. Claude pays very close attention to example details.[16]
- Give permission to say “I don’t know”: Explicitly tell Claude it can express uncertainty rather than guessing, which reduces hallucinations.[16]
- State what to DO, not what NOT to do: Instead of “Do not use bullet points,” try “Write in flowing prose paragraphs”.[16]
Extended Thinking
Extended thinking is one of the most impactful features for complex tasks:
- Turn it on for complex work: Extended thinking lets Claude reason step-by-step before responding. Error and hallucination rates drop significantly—the ~10–15% increase in token cost pays for itself in quality.[17][18]
- Give high-level direction, not step-by-step prescriptions: Claude often performs better with instructions like “Think deeply about this” rather than overly prescriptive reasoning steps. Its creativity in approaching problems may exceed a human’s ability to prescribe the optimal process.[19]
- Use multishot examples with thinking tags: Include <thinking> or <scratchpad> tags in your examples to show Claude how to reason through similar problems.[19]
- Start with a small thinking budget and increase as needed: Avoid pushing Claude to output more tokens for the sake of it. Find the optimal settings for each use case.[19]
Structuring Prompts Like a “Contract”
A well-structured prompt reads like a short contract:[20]
| Element | Purpose | Example |
| Role | Sets perspective | “You are a senior data analyst” |
| Output rules | Format, length, tone | “Reply in 3–5 bullet points” |
| Disallowed behavior | Hallucination/citation policy | “If unsure, say so” |
| Verification | Self-check instructions | “Confirm all figures against source” |
Additional checklist items before deploying any important prompt:[20]
- Goal stated first (what “done” looks like)
- 1–2 examples included (if format matters)
- Sections clearly separated (use headers)
- Evaluator checklist appended (for critical prompts)
Using XML Tags for Structure
While less necessary with newer models, XML-style tags remain useful for complex prompts:[21]
- Wrap sections in <task>, <rules>, or <examples> tags to create clear boundaries
- Place tone, policy, or tool-use rules in the system prompt
- Use <thinking> or <scratchpad> tags to separate reasoning from final output
Prompt Chaining (Multi-Step Tasks)
Break complex tasks into sequential prompts where each output feeds the next:[16]
- Draft: “Summarize this paper covering methodology, findings, and implications”
- Review: “Review the summary above for accuracy and completeness. Provide graded feedback”
- Refine: “Improve the summary based on this feedback”
This increases latency but dramatically improves accuracy for complex work.[16]
Modularize Ideas Into Consecutive Prompts
Instead of cramming everything into one prompt, split work into separate but consecutive prompts whose outputs combine into a richer product. This works especially well for sections of code, research tasks, and staged processes.[17]
Iterative Refinement Over Starting Over
When Claude’s output is not quite right, build on what exists rather than regenerating from scratch. Provide more specific constraints to iterate toward the desired output. Avoid negative framing (“No, that’s wrong”) and use neutral corrections instead: “That’s not quite right. Here’s specifically what I need”.[22][23][17]
Prefilling Responses
Guide Claude’s output format by starting its response for it (especially useful via the API):[16]
- Force JSON output by prefilling with an opening brace {
- Skip conversational preambles by being explicit: “Output only valid JSON with no preamble”
- Control the structure of reports by providing skeleton outlines for Claude to complete
Projects: Organize Context
Claude Projects maintain context and organization across conversations:[24][25]
- Create dedicated projects for recurring workstreams (e.g., “Blog Writing,” “Research,” “Course Development”)
- Upload reference documents to the project knowledge base
- Set project-level system prompts to anchor Claude’s behavior for that context
- Use the knowledge base for style guides, brand guidelines, technical documentation, and frequently referenced materials
Custom Styles
Most users overlook Claude’s custom styles feature:[26]
- Feed Claude samples of your actual writing to create a reusable style profile
- Manually edit the style for full control rather than accepting Claude’s summary of your style
- Create blended styles by having Claude analyze writing from authors you admire and combining them with your own voice
- Apply styles across your entire account, not just one project
- Manage multiple brand voices for client work or different content channels
Skills and Artifacts
Claude Skills are reusable folders of specialized knowledge (instructions, best practices, examples) that load on demand:[27]
- Build Skills for tasks repeated weekly (e.g., “Brand Guidelines,” “Content Calendar,” “Financial Reporting”)
- Skills free users from repeating the same prompts—Claude already has the context it needs
- Skills support YAML frontmatter for controlling behavior: user-invocable, context forking, and allowed tools[23]
Claude Artifacts are live previews of interactive tools, documents, and visualizations:[27]
- Request Artifacts for calculators, form processors, data visualizers, dashboards, and mini-apps
- Artifacts support iterative development—Claude can selectively update specific sections without regenerating the entire output[24]
- Combine Skills (what Claude knows) with Artifacts (what tools you build) for maximum impact
Memory Management
Claude’s memory features reduce repetitive context-setting:[28][29][30]
- Project Memory: Edit what Claude remembers directly in project settings. Use concise pointers: “Do X, reference Y framework, avoid Z pattern”[30]
- md files (for Claude Code): Create persistent memory at user scope (~/.claude/CLAUDE.md) and project scope (CLAUDE.md in root). After every correction, end with: “Update your CLAUDE.md so you don’t make that mistake again”[28][23]
- Friction-driven feedback: When Claude produces suboptimal output, don’t just fix it—ask Claude to adjust its memory: “Create bold statements that stop readers from scrolling”[30]
Claude Code Power Tips (from Creator Boris Cherny)
These tips come directly from the Anthropic team’s own usage, shared in a viral thread with 8.5 million views:[23]
- Run 3–5 parallel git worktrees: Each worktree gets its own Claude Code session running simultaneously—the team’s single biggest productivity unlock
- Start in Plan Mode (Shift+Tab): Invest in planning so Claude can one-shot the implementation. Review, refine, then switch to auto-accept
- Invest in md memory: After every correction, have Claude write rules for itself to prevent repeated mistakes
- Create reusable Skills: Build slash commands for recurring workflows (tech debt analysis, code review, analytics)
- Use MCP integrations: Connect Claude directly to bug trackers, CI logs, and error monitoring tools for outcome-based prompting (“Fix the failing CI tests”)
- Challenge Claude as a code reviewer: Flip the dynamic—ask Claude to “grill you” on your changes before PR submission
- Customize your terminal: Use Ghostty with /statusline for tracking context usage, cost, and git branch across parallel sessions
- Leverage subagents: Say “use subagents” to launch multiple parallel agents for research, exploration, and complex multi-step tasks
- Use Claude for data analytics: Let Claude write queries, run them, and interpret results (BigQuery, PostgreSQL, etc.) without leaving your dev environment
- Enable learning output styles: Let Claude adapt its communication style to match your preferences over time
MCP (Model Context Protocol) Integration
MCP removes manual overhead by connecting Claude to external tools:[31][32]
- Connect to GitHub, Figma, Notion, Sentry, Jira, and other tools directly
- Use /mcp in Claude Code to configure server connections
- Combine Filesystem and Sequential Thinking MCPs for data correlation and analysis[33]
- Chrome MCP lets Claude interact with a real browser to validate UI changes and verify deployed features[23]
- Tool Search can reduce token usage by up to 46.9% by optimizing context[32]
Claude Cowork for Non-Developers
For knowledge workers who don’t code, Cowork brings agentic capabilities to everyday tasks:[15][14]
- Point Claude at a folder and describe the desired outcome
- Claude autonomously reads, modifies, and generates files while reporting progress
- Use cases: organizing messy files, extracting receipt data into spreadsheets, drafting reports from scattered notes, producing presentations
- Integrates with connectors (Asana, Notion) and Claude in Chrome for browser-based tasks
Multi-Agent Workflows
Build “AI assembly lines” where different Claude instances handle specialized roles:[34]
- Assign roles like Research Analyst, Creative Copywriter, and Senior Editor
- Run them in sequence so each agent’s output feeds the next
- Each agent gets a clean context window, avoiding pollution from other tasks
- Use this for content production, research synthesis, and multi-step document creation
Workflow Design Principles
Beyond individual tips, the most productive Claude users think in terms of systems, not single prompts:[35]
- Build standardized prompts and reusable templates rather than reinventing each time
- Include review checkpoints: Every workflow should have a brief → template → QA → approval structure
- Use the “Claude ROI rule”: Every task needs (1) a clear brief with context and goal, (2) constraints on tone, compliance, length, and format, and (3) quality control with assumptions, risks, and a checklist[35]
- Track time saved per workflow and quality metrics to measure real ROI
- Stabilize outputs first, automate second: Get consistent results manually before adding automation[35]
