How to Automate Intellectual Toil with Agent-Driven Development on GitHub Copilot

By ⚡ min read

Introduction

Software engineers have long automated repetitive tasks to focus on creative work, but the rise of AI agents now lets you automate intellectual toil—the tedious analysis of code and data. This guide walks you through creating your own agent-driven workflow using GitHub Copilot, inspired by a real project that streamlined evaluation benchmark analysis. By the end, you'll learn to identify repetitive mental tasks, leverage Copilot to surface patterns, build and share agents, and empower your team to do the same. The original narrative about automating trajectory analysis provides the blueprint; here you get actionable steps.

What You Need

GitHub Copilot subscription (Individual, Business, or Enterprise) – must be activated for your IDE (VS Code, JetBrains, etc.)
Familiarity with JSON or similar data formats – you'll work with structured logs or outputs
Basic understanding of AI agents – what they are (e.g., autonomous code executors) and how they perform tasks
Python or JavaScript knowledge – agents can be written in any language, but Copilot works best with common ones
Access to a repository or shared space (e.g., GitHub repo) to publish and collaborate on agents
Patience and curiosity – automating intellectual work requires exploration and iteration

Step 1: Identify a Repetitive Intellectual Task

Start by examining your daily work. Look for a pattern where you repeatedly apply the same reasoning or analysis to similar data. For example, the original case involved reading hundreds of thousands of lines of JSON (agent trajectories) to evaluate performance. Write down:

What data you process (e.g., log files, test results, code outputs)
What mental steps you take (e.g., find all tasks failing a condition, summarize errors)
How much time it consumes per occurrence.

Choose a task that is rule-based (not requiring intuition) and high-volume. This is your automation candidate.

Step 2: Use Copilot to Surface Patterns

Before building your own agent, let Copilot help you understand the structure of your data. Open a sample file in your IDE, then prompt Copilot with natural language. For example:

“Analyze this JSON and count how many tasks contain an error in step 3.”
“List all unique action types across these trajectories.”

Copilot will generate code snippets that filter, aggregate, or visualize patterns. This step serves two purposes: it confirms automation feasibility and gives you starter code for your agent.

Tip: Use Copilot Chat for more interactive exploration—ask “What is the most common failure mode in this dataset?” and refine the response.

Step 3: Design an Agent to Automate the Task

Now define what your agent will do. An agent is essentially a program that receives input (your data) and produces a desired output (e.g., a summary, a report, or a decision). Keep these design principles from the original project:

Decouple input/output – the agent should accept any data in the same format.
Provide clear prompts – the agent’s behavior is driven by a prompt that describes the task. For a coding agent, the prompt might be: “Given this trajectory JSON, identify any performance regressions.”
Make debugging easy – include logging or intermediate steps so you can verify the agent’s reasoning.

Decide on a framework. You can use plain code with Copilot assistance, or leverage existing agent libraries (e.g., LangChain, Semantic Kernel). For simplicity, stick with a script that calls the OpenAI API or GitHub Copilot API (if available) to perform analysis.

Step 4: Implement the Agent with Copilot

Open a new file in your IDE and describe your agent’s purpose in comments. For instance:

# Agent: analyze_agent_trajectories.py
# Input: path to JSON file
# Output: Markdown summary of evaluation results

Start typing your logic. Copilot will auto-suggest function bodies. Use the following structure:

Read data – load JSON files from a directory.
Define analysis functions – e.g., count_errors(), find_longest_path().
Generate report – create output in a readable format (Markdown, HTML).
Iterate with Copilot – if a function is incomplete, prompt Copilot to fill it. For example, “Add a function that sorts tasks by duration.”

Tip: Use Copilot’s inline suggestions to write tests for your agent—this ensures reliability and makes it shareable.

Step 5: Share and Collaborate

The original project emphasized making agents easy to use and author. Publish your agent code in a GitHub repository. Add a README that explains:

What the agent does
How to run it (e.g., python agent.py --input ./data)
How to extend it (e.g., add new analysis functions)

Enable contributions by writing modular code. Use Copilot to help create templates for new agents: just as the original author did, make “coding agents the primary vehicle for contributions.” Encourage team members to fork and adapt.

Step 6: Empower Your Team to Create Their Own Agents

Your ultimate goal is to remove intellectual toil for everyone. Set up a collaborative workflow:

Pair programming with Copilot – mentor teammates by showing them how to use Copilot to analyze new datasets.
Create a shared agent library – a directory of reusable agents with standardized interfaces.
Document best practices – write a short guide on prompt engineering for agents (e.g., “Be specific about the output format”).
Hold regular hack sessions – where team members build agents for their own pain points.

The original narrative noted that after automation, the author now maintains the tool for peers. That’s the final stage: take care of your agents, update them as needs evolve, and watch your team’s productivity soar.

Tips for Success

Start small – automate one tiny mental step first (e.g., “count how many items have warning status”). Scale up gradually.
Pair your agent with Copilot – use Copilot to improve your agent’s accuracy and add edge cases.
Test with real scenarios – run your agent on actual data and compare results to manual analysis.
Keep agents modular – separate data reading, analysis, and output for easier reuse.
Celebrate wins – when you cut analysis time from hours to seconds, share that success with your team.
Iterate based on feedback – ask colleagues what other tasks they’d like automated.

By following these steps, you’ll not only automate your own intellectual toil but also build a culture where AI agents accelerate everyone’s creative work—just as GitHub Copilot did for the Applied Science team.
