30 Claude Features You Need to Know NOW (Become a PRO!)

The video opens by explaining that Claude Opus 4.7 features 'adaptive thinking' that is off by default, requiring specific trigger phrases like 'think carefully,' 'think harder,' or 'ultra think' to activate extended reasoning. The presenter recommends using this for high-stakes tasks like financial decisions or complex debugging, but not for simple tasks like drafting emails.

The next section covers a five-part prompt framework: Role, Task, Context, Constraints, and Format (RTCCF). The presenter also advocates using XML tags to structure complex prompts, claiming this improves output quality by 30–50% by helping Claude distinguish instructions from data. Meta-prompting — asking Claude to rewrite your own prompt — is presented as a recursive technique that reliably improves results. Flipping the dynamic by asking Claude to interview you with 5–7 clarifying questions before starting is also recommended for complex tasks.

The video then covers Claude's personal settings, including the 'Instructions for Claude' profile field for persistent preferences, memory generation from chat history with hygiene recommendations, and custom writing styles created by uploading your own writing samples. Claude's ability to search previous conversations on demand is highlighted as turning chat history into a knowledge base. An incognito mode and cross-platform memory import from ChatGPT or Gemini are also mentioned.

Projects are described as scoped workspaces with file libraries, supporting up to 20 files and 30MB on the free plan. Artifacts are interactive, stateful outputs that can store up to 20MB of data when published. Live artifacts connect to data sources like Google Sheets for real-time updates. Published artifacts can call the Claude API directly via window.claude.complete without requiring an API key from end users, enabling shareable AI-powered apps.

The video covers Claude's enhanced image resolution (2,576px / 3.75MP in Opus 4.7), useful for reading fine text in documents, dashboards, and medical or financial data. A three-level PDF summary prompt structure is recommended, including asking Claude to identify gaps the document doesn't address.

Connectors allow Claude to access Gmail, Google Drive, Google Calendar, Slack, Notion, GitHub, Salesforce, and the full Microsoft 365 suite. A Microsoft Office add-in embeds Claude across Excel, PowerPoint, Word, and Outlook with shared context. Research mode is described as an autonomous agent that browses dozens of sources and returns a cited multi-page report in 3–15 minutes, available on paid plans.

Skills are reusable workflows stored in a skill.md file, with built-in skills for Office formats and front-end design, and third-party repositories offering thousands of community-built options. Claude Code gives Claude direct access to local files and codebases via the desktop app, with a claude.md file used to define project rules — particularly what Claude should NOT do — improving first-attempt accuracy by 3–5x. Routines in Claude Code enable scheduled automated tasks like daily commit reviews or weekly dependency audits.

Plan mode in Claude Code shows a full action plan before any files are touched, described as the responsible default for significant changes. Co-work mode turns Claude into a multi-hour autonomous agent that coordinates sub-agents, handles local files natively, and integrates with connectors simultaneously. Scheduled tasks within Co-work automate recurring workflows like morning briefings. Finally, Claude for Chrome (beta) gives Claude access to the user's authenticated browser sessions for tasks like competitive research, with a strong security caution about not using it with banking or medical portals. Claude Design is briefly introduced as a separate tab for non-designers building prototypes.
