Here is a small tool I shipped last week: a command-line architecture advisor that uses chain-of-thought reasoning to sanity-check infrastructure decisions. It takes a plain-English scenario, thinks through constraints and tradeoffs, and returns a structured JSON report you can paste into a design doc. I built it on Oxlo.ai because flat per-request pricing keeps costs predictable even when the model generates long reasoning traces. See https://oxlo.ai/pricing for details.
What you'll need
- An Oxlo.ai API key from https://portal.oxlo.ai
- Python 3.10 or newer
- The OpenAI SDK:
pip install openai
Step 1: Configure the Oxlo.ai client
First, import the SDK and point it at Oxlo.ai. The base URL and API key are the only changes needed because the platform is fully OpenAI compatible.
from openai import OpenAI
client = OpenAI(
base_url="https://api.oxlo.ai/v1",
api_key="YOUR_OXLO_API_KEY" # Get yours from https://portal.oxlo.ai
)
Step 2: Define the reasoning system prompt
The prompt tells Kimi K2 Thinking to act as a staff engineer and emit a strict JSON schema after it finishes reasoning.
SYSTEM_PROMPT = """You are a senior staff engineer performing architecture reviews.
Given a technical scenario, reason step by step about requirements, constraints, and tradeoffs.
After your analysis, output a single valid JSON object with no markdown formatting.
Use this exact schema:
{
"scenario_summary": "string",
"key_constraints": ["string"],
"options_considered": [
{"name": "string", "pros": ["string"], "cons": ["string"]}
],
"recommendation": "string",
"risks": ["string"]
}"""
Step 3: Create the analysis function
This function sends the user question to the Kimi K2 Thinking model and returns the response text. I keep the temperature low so the reasoning stays grounded and repeatable.
def analyze_architecture(question: str) -> str:
response = client.chat.completions.create(
model="kimi-k2-thinking",
messages=[
{"role": "system", "content": SYSTEM_PROMPT},
{"role": "user", "content": question},
],
temperature=0.2,
)
return response.choices[0].message.content
Step 4: Parse and display the result
Real tools need reliable output. I wrap the call in a small runner that parses JSON and pretty-prints it, falling back to raw text if the model returns something unexpected.
import json
def run_analysis(question: str):
raw = analyze_architecture(question)
try:
parsed = json.loads(raw)
return json.dumps(parsed, indent=2)
except json.JSONDecodeError:
print("Warning: model did not return valid JSON. Raw output:")
return raw
if __name__ == "__main__":
query = (
"I need to store and query 10 TB of log data with sub-second latency "
"for a security dashboard. What stack should I use?"
)
print(run_analysis(query))
Run it
Execute the script from your terminal. Kimi K2 Thinking will reason through storage engines, indexing strategies, and cost tradeoffs before emitting the structured report. Here is an example of the parsed output:
{
"scenario_summary": "High-volume log storage and querying for security dashboards requiring sub-second latency across 10 TB of data.",
"key_constraints": [
"10 TB cumulative volume",
"Sub-second query latency",
"Cost-effective long-term retention"
],
"options_considered": [
{
"name": "Elasticsearch with hot-warm architecture",
"pros": ["Fast full-text search", "Mature ecosystem"],
"cons": ["License costs at scale", "Heavy memory usage"]
},
{
"name": "ClickHouse on object storage",
"pros": ["Excellent compression", "Fast aggregations"],
"cons": ["Operational complexity", "Less flexible text search"]
}
],
"recommendation": "Start with ClickHouse for high-cardinality aggregations and keep a small Elasticsearch hot tier for raw text search.",
"risks": [
"Operational overhead of running two storage systems",
"Data duplication costs"
]
}
Next steps
Wire the run_analysis function into a Slack bot or CI pipeline so every pull request that touches infrastructure gets an automated reasoning check. If you need to process large design documents as context, remember that Oxlo.ai's flat per-request pricing means you can pass long prompts and extended reasoning chains without watching token meters run up.
