📝 Walkthrough

Summary by CodeRabbit

  • New Features
    • Introduced an HTTP API to generate 200–300 word articles from a provided topic.
    • Added support for multiple AI providers with model validation and clear error responses for invalid inputs.
    • Exposed an endpoint to list available providers and their models.
    • Implemented robust error handling with informative messages for failed generations.
  • Chores
    • Minor console output updates for testing and verification.

Walkthrough

Adds new Express-based HTTP APIs to generate short articles: one generic provider-driven server under src/llm/providers.py and another OpenAI-backed server at wanda/server.js. Updates src/henry.py by duplicating a print and appending non-Python text lines, introducing syntax-invalid trailing content.

Changes

Cohort / File(s) Change summary
Python script edits
src/henry.py
Increased identical print statements from 1 to 5; added a blank line; appended four plain-text lines that are not valid Python, causing a syntax error.
Provider-based article API server
src/llm/providers.py
New Express server: loads env, enables CORS/JSON/static. Endpoints: GET /api/providers (lists providers), POST /api/generate-article (validates topic/provider/model, builds prompt, calls provider.generate, returns article/provider/model). Error handling with 400/500 responses.
OpenAI-backed article API server
wanda/server.js
New Express server: loads env, initializes OpenAI client, enables CORS/JSON/static. Endpoint: POST /api/generate-article (validates topic, calls gpt-3.5-turbo chat completion with system/user prompts, returns article). Error handling with 400/500 responses.

Poem

A bunny taps the server logs—thump-thump, green glow,
Two APIs sprout where cool drafts flow.
One calls its providers, lined in a row,
One whispers to OpenAI, “Ready? Go!”
Henry shouts five times—then trips on prose below. 🐇✨

Walkthrough

This PR introduces server-side functionality for article generation using Express.js, but contains several critical issues. It adds a JavaScript Express server in the Wanda directory that integrates with OpenAI's API to generate articles based on user-provided topics. However, it also introduces problematic changes: invalid Python code in henry.py with plain text that will cause syntax errors, and a mismatched file (providers.py) containing JavaScript code despite having a Python extension. These issues need to be addressed before merging to ensure proper functionality and file organization.

Changes

File(s) Summary
src/henry.py Added duplicate print statements and invalid plain text (not properly formatted as Python comments) that will cause syntax errors.
src/llm/providers.py Added new file with JavaScript Express.js server code despite having a Python (.py) extension. Implements endpoints for retrieving LLM providers/models and generating articles.
wanda/server.js Added new Express.js server that integrates with OpenAI's API to generate articles via a POST endpoint (/api/generate-article). Includes proper error handling, middleware configuration, and environment variable support.

correctness: completion.choices[0].message.content may throw if choices is empty or message/content is missing, causing a runtime crash for unexpected OpenAI API responses.

🤖 AI Agent Prompt for Cursor/Windsurf

📋 Copy this prompt to your AI coding assistant (Cursor, Windsurf, etc.) to get help fixing this issue

In wanda/server.js, lines 44-45, the code assumes that `completion.choices[0].message.content` always exists, but if the OpenAI API returns an unexpected response (e.g., empty choices), this will cause a runtime crash. Add a check to ensure `choices`, `choices[0]`, `message`, and `content` exist before accessing them. If not, return a 502 error with an appropriate message.

security: topic from req.body is directly interpolated into the OpenAI prompt without sanitization, enabling prompt injection attacks that can manipulate model output or leak sensitive information.

🤖 AI Agent Prompt for Cursor/Windsurf

📋 Copy this prompt to your AI coding assistant (Cursor, Windsurf, etc.) to get help fixing this issue

In wanda/server.js, lines 22-37, the `topic` value from `req.body` is directly interpolated into the OpenAI prompt, making the endpoint vulnerable to prompt injection attacks. Please sanitize the `topic` input to remove newlines and special characters before using it in the prompt. Replace the direct usage of `topic` with a sanitized version to prevent prompt injection.

2-5: Remove duplicate prints (noise).

Unless intentionally testing logging, keep a single print.

-print("Henry testing v0.8.0")
-print("Henry testing v0.8.0")
-print("Henry testing v0.8.0")
-print("Henry testing v0.8.0")
+# print once
wanda/server.js (3)

28-31: Prefer current models; 3.5 is legacy for new apps.

Consider switching to gpt-4o or gpt-4o-mini for better quality/cost; Chat Completions remains supported. (github.com)

-    const completion = await openai.chat.completions.create({
-      model: "gpt-3.5-turbo",
+    const completion = await openai.chat.completions.create({
+      model: "gpt-4o-mini",

44-48: Improve error logging with request IDs; keep response generic.

The SDK exposes a request_id to aid debugging without leaking details to clients. (github.com)

-  } catch (error) {
-    console.error('Error:', error)
+  } catch (error) {
+    console.error('Error:', { name: error?.name, status: error?.status, requestId: error?._request_id, message: error?.message })
     res.status(500).json({ error: 'Failed to generate article' })
   }

14-17: Optional: tighten CORS and JSON size, add security headers.

Lock CORS to known origins, cap JSON body size, and add helmet.

-app.use(cors())
-app.use(express.json())
+app.use(cors({ origin: process.env.ALLOWED_ORIGINS?.split(',') || [] }))
+app.use(express.json({ limit: '32kb' }))
+// const helmet = require('helmet'); app.use(helmet());

🔇 Additional comments (2)
wanda/server.js (1)

1-4: FYI: ESM import is the documented pattern.

The SDK docs show import OpenAI from 'openai' (ESM). Your CommonJS require('openai') can work depending on tooling, but if you move to ESM, update import and package.json ("type": "module"). (github.com)

src/llm/providers.py (1)

17-23: Name collision risk and unclear module path.

const providers = require('./src/llm/providers') from within a “providers” file is confusing and may resolve incorrectly. After moving to JS, import the registry with a clear path (e.g., ./providers).

⚠️ Potential issue

Wrong language/file type: Node/Express code checked into a .py file.

This won’t run and will trip Python linters/CI. Also, it appears to start another Express server on port 3000, duplicating wanda/server.js and risking port conflicts.

Apply these steps:

  • Move this server to a JS/TS file (e.g., src/llm/server.js) and remove src/llm/providers.py.
  • Ensure the providers registry lives in a separate module (e.g., src/llm/providers/index.js) and import it with a relative path from the server (no self-require).
  • Pick a single server (merge with wanda/server.js) or use a distinct port to avoid conflicts.

Delete mistaken Python file:

- require('dotenv').config()
- const express = require('express')
- const cors = require('cors')
- const path = require('path')
- const providers = require('./src/llm/providers')
- ...
- app.listen(port, () => {
-   console.log(`Server running on port ${port}`)
- }) 
+ # (file removed; moved to JS)

New server file (outside current range) for clarity:

// src/llm/server.js
require('dotenv').config()
const express = require('express')
const cors = require('cors')
const providers = require('./providers') // e.g., src/llm/providers/index.js

const app = express()
const port = process.env.PORT || 3001 // avoid 3000 clash with wanda/server.js

app.use(cors())
app.use(express.json())

app.get('/api/providers', (req, res) => {
  const info = Object.entries(providers).map(([id, p]) => ({ id, name: p.name, models: p.models }))
  res.json(info)
})

app.post('/api/generate-article', async (req, res) => {
  const { topic, provider: providerId, model } = req.body
  if (typeof topic !== 'string' || topic.trim().length === 0 || topic.length > 512) {
    return res.status(400).json({ error: 'Topic is required' })
  }
  const p = providers[providerId]
  if (!p) return res.status(400).json({ error: 'Invalid provider' })
  if (!model || !p.models.includes(model)) return res.status(400).json({ error: 'Invalid model for provider' })
  try {
    const prompt = `Write a short, informative article about ${topic}. The article should be between 200-300 words.`
    const article = await p.generate(p.client, model, prompt)
    res.json({ article, provider: p.name, model })
  } catch (err) {
    console.error(`Error with ${p.name}:`, err)
    res.status(500).json({ error: `Failed to generate article using ${p.name}` })
  }
})

app.listen(port, () => console.log(`Server running on port ${port}`))

Unify both servers behind one Express app if possible to simplify deployment and routing.

In src/llm/providers.py (lines 1-60) the file contains a Node/Express server
mistakenly checked in as a .py file and starts an Express app that may conflict
with wanda/server.js; delete src/llm/providers.py, create a JS module for the
providers registry at src/llm/providers/index.js (export an object keyed by
provider id with name, models, client, generate), move the Express server code
into src/llm/server.js and import the providers with a relative path
(require('./providers')), remove any duplicated server startup from the
providers module, and either merge this server into wanda/server.js or change
the port (e.g., use process.env.PORT || 3001) and update package.json scripts to
run the new server; ensure all imports/exports use correct JS module syntax and
no self-require from the same file.

Add client reliability controls and early API key validation.

Configure OpenAI SDK timeouts/retries and fail fast if OPENAI_API_KEY is missing. The SDK supports maxRetries and timeout on the client. (github.com)

🤖 Prompt for AI Agents
In wanda/server.js around lines 10 to 12, the OpenAI client is created without
API-key validation or reliability settings; add an early check that
process.env.OPENAI_API_KEY exists and exit with a clear error if missing, and
instantiate OpenAI with client reliability options (set timeout in ms and
maxRetries) to avoid hanging and auto-retry behavior; choose sensible defaults
(e.g., timeout 30_000 and maxRetries 2–3) and ensure the env value is passed
securely to the client configuration.

Harden input validation.

Validate string type, trim, and length to avoid abuse and excessive prompt sizes.

In wanda/server.js around lines 24 to 26, the current check only ensures topic
exists but doesn't validate type, trimming, or length; update the validation to
ensure topic is a string, trim whitespace, reject empty strings after trim, and
enforce a maximum safe length (e.g., 1000 characters) to prevent abuse or
excessively large prompts; if validation fails return res.status(400).json with
a clear error message indicating which check failed.
