TagDebt: A Bot to Support Technical Debt Management
This paper presents TagDebt, a GitHub bot designed to automatically identify and label self-admitted technical debt issues, which practitioners found useful for streamlining debt management workflows while noting that adoption is influenced by team and codebase size.

Imagine you are building a house. Sometimes, to finish a room quickly before a deadline, you might use a shortcut: you leave a note on the wall saying, "Fix this wobbly floor later," or you use cheap nails instead of strong ones. In software development, these shortcuts are called Technical Debt. Just like financial debt, it's not always bad to take it on if it helps you move fast, but if you never pay it back, the interest piles up, the house becomes unsafe, and eventually, it might collapse.
The problem is that in big software projects, these "notes on the wall" (shortcuts) get lost. Developers forget about them, or they get buried under hundreds of new tasks.
This paper introduces a solution called TagDebt, which acts like a super-organized digital assistant (a "bot") for software teams. Here is how it works, broken down simply:
The Problem: The "Lost Note" Syndrome
In software, developers often write down their shortcuts in "Issues" (like to-do lists or bug reports) on a platform called GitHub. They might write, "This code is messy, we need to fix it later."
- The old way: A human has to read every single note, realize it's a "debt," and manually tag it. This is boring, time-consuming, and people often forget to do it.
- The result: The debt piles up, and the software becomes harder to fix over time.
The Solution: TagDebt (The Digital Librarian)
The researchers built TagDebt, a bot that lives inside the software project's "library" (GitHub). Think of it as a smart librarian who instantly reads every new note a developer writes.
- It Reads and Understands: When a developer writes a note like, "We rushed this feature, the code is messy," TagDebt uses AI (a type of computer brain) to read the text. It understands that this is a "debt" note, even if the developer didn't use a special code word like "TODO."
- It Tags the Note: Instead of waiting for a human to find it, the bot automatically sticks a digital label on the note that says, "This is Technical Debt."
- It Alerts the Team: If the team wants, the bot can send an email to the right people saying, "Hey, we have a new debt item to look at."
How They Tested It
The researchers didn't just build the bot; they tested it with 16 real software professionals (developers, managers, and architects). They asked them to try using the bot and then interviewed them to see what they thought.
What the humans said:
- "It's a time-saver!" Most people felt the bot was very useful because it stopped them from doing the boring work of manually tagging notes. It helped them see all their "debt" in one place, like a map of all the wobbly floors in the house.
- "It's easy to set up." They found it simple to install and configure, mostly because it fits right into the tools they already use (GitHub) without needing a complicated new system.
- "It depends on the team size." The bot was most helpful for larger teams (like a construction crew of 10–25 people). For a tiny team of one or two people, the bot felt a bit unnecessary because they could just talk to each other about the mess.
- "We need more details." Some people wanted the bot to explain why it tagged something as debt, not just give a generic label. They also wanted it to be able to look at the actual code, not just the notes.
The Big Takeaway
The paper concludes that TagDebt is a successful "proof of concept." It proves that you can build a specialized tool that helps manage software debt without disrupting how developers already work.
- For small teams: It might be overkill.
- For big teams: It acts like a safety net, catching the "messy notes" before they get lost and causing bigger problems later.
The researchers emphasize that this bot isn't there to replace human judgment. Instead, it's like a spotlight that shines on the problems so the humans can decide what to fix first. It makes the invisible debt visible, helping teams keep their software house from falling apart.
