What does the actual workflow look like for using Claude to ...

Using Claude for development work isn't just about typing questions into a chat window — it's about building a repeatable, structured workflow that lets you move from "I have no idea what I'm doing" to shipping working code faster than you'd believe possible. As someone who builds production AI agents on top of Claude (including Buddy, an open-source Google Ads agent), I've learned that the practitioners who get the most out of Claude aren't necessarily the best programmers — they're the ones who've figured out the right workflow rhythms.

Why "Just Ask Claude" Isn't Actually a Workflow

A common question in the r/ClaudeAI community centers on something deceptively simple: what does the actual workflow look like? One thread captured it well — a new developer said they were struggling not with Claude's answers, but with the "practical aspects of incorporating" those answers into their project. That's the real gap most beginners fall into.

Asking Claude a question and getting a code block back is table stakes. The workflow is everything that surrounds that exchange: how you structure your project context, how you feed Claude information about your existing code, how you validate what it gives you, and how you iterate without losing your mind (or your codebase).

Think of it less like using a search engine and more like pair programming with a very fast, very knowledgeable colleague who has zero memory of what you worked on yesterday — unless you explicitly remind them.

Phase 1 — Project Setup and Context Priming

Before you write a single line of code with Claude's help, spend time on what I call the "project brief." This is a structured document (even just a plain text file) that you paste at the start of every new Claude session. It should contain:

• Project description: What you're building in 2-3 sentences. Don't be vague. "A Python script that pulls Google Ads performance data via the API and writes it to a Google Sheet" is infinitely more useful than "an automation tool."
• Tech stack: Language, framework versions, key libraries. "Python 3.11, using google-ads 21.1.0, gspread 6.0.0, running on Ubuntu 22.04."
• Current file structure: A simple directory tree. You can generate this with tree on Mac/Linux or paste it manually.
• What's already working: Describe what's done so Claude doesn't suggest rewriting it.
• The specific problem for this session: One focused problem per session. Seriously — one.

How Long Should Your Context Be?

This is where new users either over-share or under-share. A good rule of thumb from my own projects: paste in the files directly relevant to the problem — usually 1-3 files — and describe the rest. Claude doesn't need your entire codebase to fix a specific function. It needs the function, the data it receives, and what you expect it to output.

If you're on Claude's extended context tiers, you can go bigger. But I've found that more focused context = higher quality output, regardless of token limits. Noise is still noise at 200K tokens.

Phase 2 — The Ask-Implement-Test Loop

This is the core of the actual development workflow, and it's where most beginners stumble because they skip the "test" step and go straight back to asking.

1. Ask one specific, scoped question. Not "help me build authentication" — instead "write a function that takes a username and password, hashes the password with bcrypt, and checks it against a value stored in a SQLite database. Here's my current database schema: [paste schema]."
2. Read the response before copying it. I know it's tempting to just paste it in. Spend 60 seconds reading the logic. Claude will often include comments explaining what each block does — read those.
3. Implement it in isolation first. Create a small test script that runs just that function with a couple of hardcoded inputs. Don't drop it straight into your main application.
4. Test it. Actually run it. Copy the exact error message or unexpected output.
5. Paste the error back into Claude with context. "I implemented the function you gave me. Here's the exact error I'm getting: [error]. Here's the function as it currently looks in my file: [code]. Here's how I'm calling it: [call]."

Managing Session Length

A practical reality of working with Claude on longer development sessions: the quality of responses can subtly drift as a session gets very long and complex. The model is working within a context window, and when that window gets cluttered with a long back-and-forth, its recommendations can start to conflict with earlier advice.

My rule: if a session has gone past roughly 15-20 exchanges on a complex topic, consider starting a fresh session with your updated claude_context.md. Yes, it takes a few minutes to re-prime. It's worth it.

Phase 3 — Code Review and Explanation Requests

One of the most underused Claude workflows for beginners is the pure "explain this to me" pass. After Claude writes code that works, ask it to walk you through what it did and why. This isn't wasted time — it's how you actually level up as a developer rather than just shipping code you don't understand.

A pattern that works well:

• "Explain this code to me line by line as if I understand basic Python but have never worked with async functions before."
• "What are the edge cases this doesn't handle? What would break it?"
• "Is there a simpler way to accomplish the same thing? Walk me through the tradeoffs."

As practitioners who build on top of Claude often discuss, the model is genuinely excellent at adapting its explanation depth. You can tell it your experience level explicitly and it will calibrate. This is especially valuable in marketing and advertising tech contexts — I've used this exact pattern when building parts of Buddy to understand Google Ads API response structures I'd never worked with before.

Phase 4 — Structuring Bigger Features Across Sessions

When you're building something non-trivial — say, a multi-step data pipeline, a web scraper with authentication, or an API integration — you can't do it all in one session. You need a way to break it into pieces that Claude can handle well.

The Feature Decomposition Approach

Before starting development on a bigger feature, I'll have one session with Claude that's purely planning. I describe what I want to build and ask Claude to:

1. Break it into discrete, testable components
2. Describe the inputs and outputs of each component
3. Suggest what order to build them in and why
4. Flag any dependencies or potential complications

I then save that breakdown as a feature_plan.md file in my project. Each subsequent session focuses on exactly one component from that list. This keeps me from scope-creeping mid-session and keeps Claude's responses tightly scoped.

Phase 5 — Debugging Workflows That Actually Work

Debugging with Claude is its own skill. The instinct is to describe the problem in general terms. The effective approach is to give Claude everything it needs to reason about the specific failure.

The Debugging Brief

When something breaks, structure your debugging request like this:

1. What you expected to happen: "I expected the function to return a list of dictionaries with keys 'campaign_id' and 'clicks'."
2. What actually happened: Include the full error traceback, or describe the unexpected output precisely.
3. The relevant code: The function and any functions it calls. Not your entire script.
4. Your environment: OS, language version, relevant library versions if the error might be version-related.
5. What you've already tried: This prevents Claude from suggesting things you've already ruled out.

When Claude Gets It Wrong

This happens. Claude is not infallible, and it can confidently produce code that looks right but has subtle bugs. A few patterns I've encountered:

• Using deprecated API methods (especially with libraries that have changed significantly in the last 2 years)
• Off-by-one errors in loops and index operations
• Race conditions in async code that only surface under load
• Missing error handling for edge cases it didn't anticipate

When you suspect Claude gave you something wrong, ask it directly: "I'm not confident this is handling [specific edge case] correctly. Walk me through exactly what happens when [edge case input] is passed to this function." Claude is very good at catching its own errors when you point it in the right direction.

Connecting This to Marketing & Advertising Tech Workflows

If you're building automations in the marketing space — pulling ad performance data, building reporting scripts, automating campaign adjustments — this workflow pays dividends quickly. When I built Buddy, the Google Ads agent, the tightest bottleneck wasn't Claude's capability. It was my ability to maintain clean context across sessions as the codebase grew.

For marketers building their first scripts (pulling Google Ads data into Sheets, automating Facebook reporting, building keyword research tools), the same principles apply. Your "project brief" should include the API you're working with, example API responses you've already received, and the exact business logic you're trying to implement. A Google Ads API response structure pasted into context is worth more than a 10-paragraph description of what you're trying to do.

What to Do Next

If you're newer to using Claude for development, here's the concrete starting point:

1. Create your claude_context.md file right now. Even if it's just 5 lines describing your project and tech stack. Start the habit before you need it.
2. Practice the Ask-Implement-Test loop on something small. Ask Claude to write a function, implement it in an isolated test file, run it, and report back the exact output — even if it works. Build the muscle memory of testing before integrating.
3. Do one "explain this to me" pass per session. Pick one function from this session's work and ask Claude to explain it and identify its weak points. This is how you actually learn.
4. Use feature decomposition for your next non-trivial task. Before coding, have a planning session. Save the output. Reference it in every subsequent session for that feature.
5. Keep a running "what I've tried" note during debugging. Before going to Claude, write down what you've already attempted. You'll give Claude better context and you'll often solve it yourself in the process.

The practitioners who get the most out of Claude aren't the ones with the most AI experience — they're the ones who treat it like a structured collaboration rather than a magic box. Build the workflow habits now, and they'll scale with you as your projects get more complex.
