Istanbul | Claude Code: The Prompt Layer

Join a Claude Community Event, organized by local enthusiasts for everyone who loves building with Claude Code!The issue is not in the tool, but in the command. Most users write the prompt like a wish sentence: "fix this error", "add a filter here". However, a powerful prompt is not a wish, but a job description. It outlines the scope, declares what is outside the scope, and most importantly, tells the tool how to understand when the job is done. Here lies the line between good users and the best: a prompt that does not provide validation criteria is an incomplete prompt.What will we do this morning?19.00 · Doors Open and ReceptionRegistration, coffee, and quick networking.19.15 · Framework: A Prompt is a SpecificationThe thesis of the day in fifteen minutes: the difference between a wish sentence and a job description and how this difference directly reflects on output quality.19.30 · Sprint 1 · From Intent to InstructionDefining scope, success criteria, and what is out of scope. Shaping the plan in planning mode without touching the code; telling Claude how to understand when the job is done.Output: A job description prompt written for your own project, containing validation criteria.20.15 · Sprint 2 · At the WheelThe job does not end when the prompt is sent; it begins. Stopping Claude, challenging its plan, correcting the course. How context hygiene with 'clear' and 'compact' quietly deteriorates the output quality of an inflated context window.Output: A route correction practice implemented in the live session and your own steering control checklist.21.00 · Short BreakRefreshments and free conversation.21.10 · Sprint 3 · Engineering the RedundancyA good prompt is written once, invoked infinitely. Laying the first stones of your personal prompt library with custom slash commands.Output: At least two custom commands committed to your repository.21.50 · ClosingGroup photo, Claude stickers, and networking.Who should attend?Those who have established and regularly use Claude Code but suspect that output quality is a bit too dependent on luck. This event is not a beginner session; it appeals more to those who want to drive it better than those who have never opened the tool. Developers are at the center; product managers and technical writers who have a good relationship with the terminal also find their place at the same table.Participation in The Markdown Layer is not a prerequisite. But the two events complement each other: one establishes the tool’s memory, delivering this morning's steering.PreparationWhat you need to bring: A laptop with Claude Code installed, an active Claude account, and a real project you wish to work on. The project does not need to be large; it just needs to be real.FacilitatorFatih Güner · Founder of Community and Locomotive AIHaving provided AI training to over 13,000 professionals, the founder of Turkey's most active AI community.
