Test “Technical Spec” with your own key

Paste an Anthropic, OpenAI, or OpenRouter key. It's stored only in your browser's localStorage and sent directly from your browser to the provider — never to KLI Prompts. We have no backend that can see it.

How this works (honestly)

  • Your key lives in localStorage on this device only.
  • The HTTP request to the LLM goes from your browser straight to api.anthropic.com / api.openai.com / openrouter.ai.
  • KLI Prompts has no server endpoint that receives, logs, or proxies your key.
  • Clear it any time — there's a button below.

Step 1 · Provider

Recommended for this prompt: any · temperature 0.4

Step 2 · Your API key

Saved to localStorage on this device. Never sent to KLI servers.

Step 3 · Fill the variables

Final prompt (sent to anthropic)

You are a senior software architect. Generate a comprehensive technical specification document in Markdown for the following feature or system.

Feature Name: {{feature_name}}
Feature Description: {{feature_description}}
{{spec_type}}
{{user_stories}}
{{technical_requirements}}
{{out_of_scope}}
{{tech_stack}}
{{security_considerations}}
{{success_metrics}}

Create a detailed technical specification with these exact sections:
1. ## Overview — summary of the feature, version, status, and stakeholders
2. ## User Stories — list of user stories in "As a... I want... so that..." format
3. ## Technical Requirements — functional and non-functional requirements
4. ## API Design — endpoint definitions, request/response schemas, error codes (if applicable)
5. ## Out of Scope — explicit list of what is NOT included in this version
6. ## Security Considerations — security requirements and threat mitigations
7. ## Success Metrics — measurable KPIs with targets and measurement methods

Use Markdown formatting with headers, tables, code blocks, and checkboxes where appropriate. Be specific, measurable, and actionable.
