Beginner tutorial: check that your paid plan can use Claude Sheets, describe the table's purpose, rules and math in one prompt, review each change Claude marks, share the sheet with coworkers to edit together, and export to Excel for heavy calculations. Also meet Claude Whiteboards and Claude Data. Includes two copy-ready prompts.

Intermediate tutorial: get Claude Code signed in with claude auth login, choose Claude Agent under /connect in OpenCode, learn which Claude Code settings stay behind, and have your AI agent move your rules into AGENTS.md. Includes 2 copy-ready prompts.

Anthropic's Claude Fable 5.2 is up to 30% faster, costs $8 per million input tokens and scores 49.1% on FrontierCode 2.0, though Opus 5.5 remains the everyday pick. Includes a table for picking the right model.

A daily trend briefing delivered automatically with sources, every item in the source table traceable, topics scored, first-draft facts easy to verify, and reusable conclusions from reviews.

An AI private tutor that works in stages: it helps you set testable goals, replaces lectures with mistakes and follow-up questions, and finally has you explain the material back to it to confirm you have really learned it.

The main session uses Sonnet, subagents go to Haiku, and Opus serves as an advisor that only reviews plans, checks repeated errors, and does final checks. The --advisor / --subagents startup flags circulating online throw errors in the current version, so this article gives working alternatives.

Advanced tutorial: Walk through four weeks with a sample Markdown-to-PDF site: in Week 1, screen for small, precise demand; in Week 2, check search results to decide page format; in Week 3, write a core page and supporting pages and link them to each other; from Week 4 on, read Search Console against a symptom lookup table. Includes two prompt templates and an experiment log template.

Advanced tutorial: Learn to read the four columns of a Search Console export, pick the 10 pages with the most clicks, and have Claude find the search queries you don't answer and the queries ranking 11 to 30. Use a reference table to decide where to add each one, then rework the opening, add unique content, link the pages to each other, request indexing, and log your changes. Includes four copyable prompts and a change log template.

A beginner's guide: set a role and constraints first, describe the goal as the finished result, ask step by step, add a line against made-up facts, then have the AI score its own answer and revise it. All five rules come with copy-ready wording and one combined template.

When the base-tier Claude quota runs out, it's usually because bulk output work was also handed to it. Keep judgment tasks for Claude, send bulk generation to Codex or a cheaper tool, and write the division of labor into CLAUDE.md.

Beginner tutorial: why AI-written text often has a distinctive tone, and how to remove it. The core principle comes from Anthropic's internal guide on removing AI flavor: if you can say it directly, say it directly. At the end is a prompt that works in both Chinese and English and suits any text model; paste it as is.

A learner handed in a Claude draft almost untouched and got an academic-integrity hearing three days later. What gave it away, what it cost, and how to actually use AI when you write.
