Prompt Basics for Claude
Learn Prompt Basics for Claude in Claude A-Z through a practical workflow, a realistic example, common limitations, and a verification checklist you can reuse.
Claude excels at nuanced language comprehension, logical reasoning, and complex instructions. To get the best answers from Claude, you don't need obscure prompt hacks — you need clear context, structured requirements, and explicit constraints.
- Role & Persona: Specify who Claude is acting as (e.g., 'Act as a senior TypeScript architect with 10 years of experience').
- Context & Objective: Provide the background story and the precise outcome you want to achieve.
- Input Data & References: Paste the source text, data table, or code that Claude needs to inspect.
- Output Constraints & Formatting: Define exactly how the output should look (e.g., 'Return a markdown table with 4 columns: Feature, Pros, Cons, and Recommendation').
One of Claude's unique architectural strengths is its ability to parse XML tags. Wrapping different sections of your prompt in semantic tags prevents ambiguity and makes complex prompts 10x more reliable:
- <context>...background information...</context>
- <instructions>...step-by-step rules...</instructions>
- <examples>...sample input and desired output...</examples>
- <data>...the raw material to process...</data>
When Claude sees structured XML tags, it clearly distinguishes your instructions from the data being analyzed, resulting in virtually zero prompt hallucination.
