Codemend AI Skill

Codemend captures production JavaScript/TypeScript errors, analyzes them with AI, and generates fixes — either as GitHub PRs or paste-back prompts for AI coding tools like Lovable, Replit, and Cursor.

Tools

report_error

Report a production error to Codemend. The error will be analyzed by AI within seconds.

bash

curl -X POST "https://codemend.ai/api/errors/ingest" \
  -H "Content-Type: application/json" \
  -d '{
    "key": "'$CODEMEND_API_KEY'",
    "message": "TypeError: Cannot read properties of undefined (reading '\''map'\'')",
    "stack": "TypeError: Cannot read properties of undefined\n    at renderList (src/components/List.tsx:15:23)",
    "source_url": "https://myapp.com/dashboard",
    "source_type": "openclaw"
  }'

Response:

json

{ "status": "queued", "error_id": "uuid-here" }

get_fix

Get the AI-generated fix for a reported error. Includes explanation, root cause, confidence score, and a fix prompt you can paste into your AI coding tool.

bash

curl -s "https://codemend.ai/api/errors/{ERROR_ID}/fix" \
  -H "x-api-key: $CODEMEND_API_KEY"

Response:

json

{
  "error": {
    "id": "uuid",
    "status": "analyzed",
    "message": "TypeError: Cannot read properties of undefined",
    "stack_trace": "...",
    "source_url": "https://myapp.com/dashboard"
  },
  "fix": {
    "id": "uuid",
    "explanation": "The map() call fails because data is undefined on first render",
    "root_cause": "Missing null check before array operation",
    "confidence": 0.92,
    "fix_prompt": "In src/components/List.tsx, add an early return if data is undefined...",
    "pr_url": "https://github.com/user/repo/pull/42"
  },
  "dashboard_url": "https://codemend.ai/errors/uuid"
}

If the error is still being analyzed, the fix field will be null. Poll with check_status first.

check_status

Check if an error has been analyzed yet.

bash

curl -s "https://codemend.ai/api/errors/{ERROR_ID}/status" \
  -H "x-api-key: $CODEMEND_API_KEY"

Response:

json

{
  "status": "analyzed",
  "message": "TypeError: Cannot read properties of undefined",
  "has_fix": true,
  "fix_id": "uuid-here",
  "dashboard_url": "https://codemend.ai/dashboard/errors/uuid"
}

Statuses: new → analyzing → analyzed / fix_applied / ignored

list_errors

List recent errors for this project.

bash

curl -s "https://codemend.ai/api/errors?limit=10&status=analyzed" \
  -H "x-api-key: $CODEMEND_API_KEY"

Response:

json

{
  "errors": [
    {
      "id": "uuid",
      "status": "analyzed",
      "message": "TypeError: Cannot read properties of undefined",
      "source_type": "openclaw",
      "has_fix": true,
      "fix_id": "uuid",
      "created_at": "2026-03-11T12:00:00Z"
    }
  ],
  "total": 42
}

Setup in a Project

Browser (React, Next.js, Vue, etc.)

Add to your HTML <head>:

html

<script src="https://codemend.ai/s.js" data-key="YOUR_API_KEY"></script>

Or if using an AI coding tool (Lovable, Replit, Bolt, etc.), paste this prompt:

Add this error monitoring script to my app. Put it in the <head> section of index.html: <script src="https://codemend.ai/s.js" data-key="YOUR_API_KEY"></script>

Node.js / Backend

bash

npm install codemend

javascript

const codemend = require('codemend');
codemend.init({ apiKey: process.env.CODEMEND_API_KEY });
codemend.setupProcessHandlers();

Express

javascript

const codemend = require('codemend');
codemend.init({ apiKey: process.env.CODEMEND_API_KEY });
app.use(codemend.expressErrorHandler());

React Native

javascript

import codemend from 'codemend/react-native';
codemend.init({ apiKey: 'YOUR_API_KEY' });
codemend.setupErrorHandler();

Typical Workflow

Set up error monitoring in your project (above)
Errors are automatically captured and sent to Codemend
Use list_errors to see recent errors
Use get_fix to get the AI-generated fix
Apply the fix: paste the fix_prompt into your AI tool, or review the PR on GitHub
