A prompt enhancer for Claude makes the task, reference material, constraints, and expected response easy to distinguish. PromptDC rewrites rough requests directly in Claude's text box so Claude can spend less effort inferring intent and more effort completing the work.
Claude prompts benefit from explicit source boundaries and well-labeled context. For long documents or code, separate the material from the instructions, tell Claude which evidence controls the answer, and define what to do when sources disagree.
Answer in 2 sentences
A Claude prompt enhancer organizes your goal, context, constraints, and output criteria into a clear instruction. PromptDC works in any text box on the web and can also transform selected text into a better prompt.
What strong Claude prompts include
- Separated context: clearly labeled instructions, source text, and examples.
- Evidence rules: which material to trust and how to handle missing facts.
- Decision criteria: the standards Claude should apply during analysis.
- Response shape: required headings, tables, files, or concise conclusions.
Claude prompt template
Task: [one outcome] Context: [background needed for the task] Source material: [paste or describe the material] Evidence rules: [use only sources, flag gaps, resolve conflicts] Constraints: [scope, tone, limits] Output: [sections, format, length] Success criteria: [checks the answer must pass]
Before and after examples
1. Analyze a long policy document
Before
Summarize this policy.
After
Using only the policy text below, prepare a briefing for customer-support managers. Identify changes to eligibility, required evidence, response deadlines, and escalation paths. Quote section numbers, flag contradictions or undefined terms, and do not infer rules that are absent. Return an executive summary, a change table, and five actions for the support team.
2. Edit while preserving the author's voice
Before
Make this essay better.
After
Edit the essay below for clarity and logical flow while preserving its conversational first-person voice. Do not add facts or make the tone academic. First list the three largest structural issues, then provide a revised version under 900 words, followed by a short note explaining every substantive change.
3. Plan a safe repository refactor
Before
Refactor this service.
After
Review the TypeScript service and tests below. Propose the smallest refactor that separates validation from persistence without changing the public API. Identify hidden coupling, preserve current error messages, and add regression tests for invalid input and database failure. Return assumptions, a file-by-file plan, code changes, and verification commands.
How to improve a Claude prompt
- Put the task before the source material.
- Label long inputs so their purpose is unambiguous.
- Define whether Claude may use knowledge outside the supplied context.
- Give evaluation criteria for analysis or recommendations.
- Request a specific deliverable and a final self-check.
Common Claude prompting mistakes
- Pasting a long document without saying what question it should answer.
- Leaving source priority unclear when documents conflict.
- Requesting a rewrite without identifying facts or voice that must remain.
- Asking for a broad code refactor without behavior to preserve.
