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.
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.
FAQ
What is a prompt enhancer for Claude?
It rewrites a rough request into labeled instructions with context, evidence rules, constraints, and a clear deliverable.
Does PromptDC work inside Claude?
Yes. PromptDC works in Claude's text box, in any other text box on the web, and on text you select on a webpage.
Should I use XML tags in every Claude prompt?
No. Labels or tags are useful when a prompt contains several kinds of material, but a short, simple request only needs clear structure.
Can PromptDC improve prompts that contain long source text?
Yes. Select the relevant text or work in the text box, then make the task and source boundaries explicit before submitting it to Claude.
Is PromptDC free?
No. PromptDC does not offer a free tier.
One desktop app for Claude and every text box
The PromptDC desktop app for macOS and Windows rewrites selected text in Claude, every desktop app, browser and text field. Use Cmd+Shift+E or Ctrl+Shift+E to review an editable result, then Replace or Copy.
PromptDC is also the first desktop app to enhance prompts inside terminal CLIs, including Claude Code, Codex CLI, Gemini CLI, Grok, Agy and OpenCode. Select the Code profile for coding prompts, and choose a default profile for each application.
The Chrome and IDE extensions are optional additions. The browser add-on supports in-place rewriting without Accessibility permission and per-site defaults; editor add-ons provide a target-agent picker and Simple or Structured output, while the desktop app already works everywhere.
