Decoding Claude: Your Troubleshooting Guide to Flawless Code Implementation

Why Does Claude Sometimes Get It Wrong?

The "Lost in Translation" Problem: Ambiguity & Lack of Context

The "Too Big to Chew" Issue: Overly Complex Tasks

• It loses focus: The longer the generation, the more likely the AI is to drift from the original instructions. It might forget a key constraint you mentioned at the beginning.
• It creates "dummy" code: To make progress, Claude might create placeholder or incomplete implementations, especially for functions that don't exist yet. This is almost never what you want.
• It grinds to a halt: Overly complex tasks in a large codebase can cause the AI to get stuck, making it difficult for it to work with the code effectively.

The "I Don't Know What I Don't Know" Dilemma: Missing Information

• The very latest version of a library or framework.
• Breaking changes in a recent update.
• The hot new dependency that everyone started using last week.

The Troubleshooting Playbook: What to Do When the Code is Wrong

Step 1: Don't Just Regenerate - Refine & Iterate

• Pinpoint the error: Be specific about what's wrong. Is it a syntax error? A logical flaw? Did it use the wrong library?
• Provide corrective feedback: Your next prompt should be a refinement of the first. For example: "That's a good start, but you've used version 2 of the XYZ library, which is deprecated. Please rewrite the code using version 3's syntax, specifically the
  1 newFunction()
  method instead of
  1 oldFunction()
  ."
• Least-to-Most Prompting: Start with a simple request & build on it. Once Claude gets the basic structure right, you can ask for more complexity, like adding error handling or edge case coverage. This lets you guide the AI & make sure it's on the right track before you go too far down the wrong path.

Step 2: The Power of

1 CLAUDE.md

- Your Project's Brain

• Coding style & standards: Tabs or spaces? CamelCase or snake_case? Document your team's conventions so Claude's output is consistent.
• Key files & modules: Point out the important files Claude should be aware of, like your main configuration file, utility functions, or core models.
• Common commands: If you have custom scripts or build commands, document them here with examples.
• Things to AVOID: This is huge. You can explicitly tell Claude things like "Do not use dummy implementations," "Always include error handling," or "Do not suggest solutions that require adding new dependencies without asking first."

Step 3: Slash Commands Are Your Best Friend

• /clear: This is your reset button. Long conversations can fill up the context window with irrelevant information, which can confuse Claude & degrade performance. Use
  1 /clear
  frequently, especially when you're switching to a new task.
• /compact: This command summarizes the conversation, which can help reduce the context size without completely wiping it. It's a good middle ground if you want to keep some of the history.
• /doctor: If you're having installation or configuration issues, this command can help diagnose what's wrong.
• Custom Slash Commands: You can even create your own slash commands! Just create a
  1 .claude/commands
  folder & add markdown files with your custom prompts. This is great for automating repetitive tasks.

Step 4: The Two-Claude Technique

1. Claude A (The Coder): This instance's job is to write the initial code.
2. Claude B (The Reviewer/Tester): Open a second terminal window & start another Claude instance. Its job is to review, critique, & test the code written by Claude A.

Prevention is the Best Medicine: Writing Prompts That Work the First Time

Be Hyper-Specific & Provide Mountains of Context

• Bad Prompt: "Create a user authentication endpoint."
• Good Prompt: "Create a JWT-based authentication endpoint for a Node.js Express API. It should be a POST request to
  1 /api/login
  . The request body will contain
  1 email
  &
  1 password
  . Use bcrypt to compare the hashed password stored in our MongoDB
  1 users
  collection (refer to
  1 @userModel.js
  for the schema). If the credentials are valid, generate a JWT signed with our
  1 JWT_SECRET
  environment variable that expires in 24 hours. Return the token in a JSON object like
  1 { "token": "..." }
  ."

Break It Down: The Power of Sequential Prompting

1. "First, create the basic HTML structure for a user profile page. Include placeholders for a profile picture, name, username, & bio."
2. "Next, let's style that page using CSS. Make the profile picture a circle & center the user's name & username."
3. "Now, let's fetch the user's data. Write a JavaScript function that makes a GET request to
   1 /api/users/{userId}
   ."
4. "Finally, populate the HTML with the data from the API response."

Assign a Role & Define Constraints

• Tone & style: "Write the code with clear, concise comments explaining the logic."
• Length: "The function should be as short & efficient as possible."
• Format: "The output should be a single Python file."
