My Claude Journey

What actually happens when you attach a PDF or a massive spreadsheet to a chat? In this episode, we reveal the two distinct paths file uploads take: direct context loading for PDFs and documents versus Python sandbox code execution for spreadsheets and data files. Learn why running code over data keeps context costs low, how Claude generates downloadable Excel, Word, and PDF files from scratch, and why you must always inspect generated formulas and formatting yourself.

Which surface should you choose when starting a new task? In this episode, we compare the web app, desktop app, and mobile app as three distinct windows onto a single cloud-based Claude account. We break down desktop-only capabilities like linked local folders and computer use, explore the mechanics of Voice Mode versus dictation, and demystify Deep Research—showing how multi-step Opus web searches compile cited reports and when they are worth the compute usage.

How do you give Claude complex, multi-step capabilities without filling up your context window on every turn? In this episode, we dissect the Agent Skills open standard and the principle of progressive disclosure. Learn how a skill folder with a SKILL.md file keeps token costs minimal by loading only a short description at startup, fetching full instructions only when needed. We also cover how to write trigger descriptions under 200 characters and set up skills in both the Claude app and Claude Code.

What happens to your conversations, files, and code after you hit send? In this episode, we unpack AI retention periods, privacy controls, and model training settings. We walk through the exact lifecycle of a chat—from history storage to 30-day server deletions and 5-year training pipeline windows. Learn what is exposed when you share public chat links, publish artifacts, or click the thumbs feedback buttons, and how to configure your settings with intention.

How does Claude hold onto your role, preferences, and ongoing projects without needing to be reminded every time? In this episode, we trace the architecture of AI memory. We examine how facts are saved in real-time as separate topics in Settings rather than through daily summaries. Discover how project memory keeps workspaces isolated, how Chat Search differs from curated memory facts, and how to view, edit, or clear what Claude remembers.

How do Claude Projects turn reference files and standing instructions into custom AI workspaces? In this episode, we examine how project knowledge reaches a chat—comparing full context loading in small projects against RAG semantic search in massive document libraries. We cover project instructions, isolated memory spaces, and the trade-offs of uploading file copies versus linking local desktop folders.

here should you place your AI instructions so they actually stick? In this episode, we evaluate the different instruction surfaces—from account-wide settings and project instructions to CLAUDE.md files and single-chat prompts. Learn how to run the sorting test to determine where rules belong, write instructions that are specific, short, and testable, and resolve conflicting guidelines across layers.

Stop getting generic AI responses by mastering the core components of effective prompting. This episode walks you through rebuilding weak prompts piece by piece using four key elements: Goal, Context, Limits, and Output Shape. Learn how to leverage concrete examples, XML tags, and document ordering to guide Claude's focus. We also cover constructive feedback loops, editing messages versus branching, and knowing when to start fresh with a handoff note.

Why do AI models hallucinate, drift, or produce generic answers? In this episode, we analyze the 9 distinct failure modes—including fabrications, invented citations, confident approximations, stale knowledge, instruction decay, sycophantic drift, and averaging. We explain why text prediction creates plausible errors and share practical verification habits, such as demanding exact source quotes, testing across fresh chats, and running pushback tests without new evidence.

How do Pro subscription limits work, and why do long chats drain your allowance so quickly? This episode demystifies Claude's resource management, covering 5-hour session limits, weekly usage caps, and pay-as-you-go usage credits. We break down per-token API pricing—explaining why output tokens cost five times as much as input tokens and how prompt caching saves money. Plus, gain actionable habits to split long tasks and stretch your compute budget.

How do you choose the right model tier for a complex job? In this episode, we compare Claude's model family—from lightweight Haiku to Sonnet, Opus, and Fable. We explore adaptive thinking, showing how forcing the model to write out its internal step-by-step reasoning catches multi-step traps and logic errors. Discover how to adjust effort levels (from Low to Max) in both the app and Claude Code to strike the perfect balance between reasoning depth, speed, and token usage.

When you type a simple message, Claude reads far more than just your text. This episode dissects the hidden prompt stack built into every turn—from Anthropic's system prompts and tool descriptions to account preferences, project instructions, memory, and tool results. Learn how prompt caching significantly cuts processing costs for unchanged setup layers. We also explore instruction decay, explaining why certain guidelines fade over time and which layers automatically reload after a long chat is summarised.

How do AI models measure text, and why do long chats start losing quality? In this episode, we unpack the mechanics of tokens and context windows—the foundational units behind AI memory, platform limits, and usage costs. We explore why Claude forgets everything between messages and must re-read the entire conversation history on every single turn. Discover why long conversations suffer from "context rot", how automatic compaction works when limits are reached, and how handoff notes can preserve your usage allowance.

What is the difference between "Claude" the AI model and the software products built around it? In this debut episode, we break down how the same underlying model runs across various surfaces—from web and desktop apps to Claude Code, browser extensions, and Microsoft Office add-ins. We examine the three levers that define every AI surface: tools, reach, and context. You'll also learn how model tiers work, how subscription allowances function across surfaces, and where each topic sits on our 23-lesson course map.
