Frameworks / How-To Guides
Elevate from errors with these refined frameworks, incorporating 2025’s context focus.
Framework 1: Context Optimization Workflow (10 Steps)
- Define goal: Pinpoint precise output wants.
- Layer context: Embed knowledge, historical past, examples.
- Delimit sections: Use ### for readability.
- Prompt reasoning: Insert “reason step-by-step.”
- Apply constraints: Define tone, size, however ethics.
- A/B take a look at: Vary for optimum variants.
- Evaluate metrics: Score accuracy, relevance.
- Iterate loops: Refine through suggestions.
- Integrate instruments: Link APIs for verification.
- Scale deployment: Embed in agentic methods.
Developer instance: Python sorting with context.
python
# Prompt: "As a senior dev, sort this list [3,1,4] step-by-step, explain each swap."
def bubble_sort(arr):
n = len(arr)
for i in vary(n):
for j in vary(0, n-i-1):
if arr[j] > arr[j+1]:
arr[j], arr[j+1] = arr[j+1], arr[j]
print(f"Swapped {arr[j+1]} and {arr[j]}")
return arr
Marketer: “Generate ad copy for eco-product, mimic brand voice from [examples].”
Small Business: “Automate invoice summaries with [data constraints].”
Executive: “Forecast trends using [Q3 data], avoid bias.”
Framework 2: Guardrail-Enhanced Model (8 Steps)
- Risk evaluation: Spot potential biases/hallucinations.
- System prompt: “Remain factual, cite sources.”
- Few-shot examples: Good/unhealthy outputs.
- Chain subtasks: Break complicated queries.
- Verify externally: API checks.
- Post-score: 1-10 on high quality.
- Log suggestions: For steady tuning.
- Audit recurrently: Align with 2025 regs.
JS no-code:
javascript
// Prompt: "Analyze unbiased summary of [article]."
async operate aiSummarize(textual content) {
const response = await fetch('https://api.openai.com/v1/chat/completions', {
methodology: 'POST',
headers: { 'Authorization': 'Bearer YOUR_KEY' },
physique: JSON.stringify({ mannequin: 'gpt-4o', messages: [{position: 'system', content material: 'Factual solely'}, {position: 'person', content material: textual content}] })
});
return (await response.json()).decisions[0].message.content material;
}
