Add /techdebt claude skill by PerfectSlayer · Pull Request #10515 · DataDog/dd-trace-java

PerfectSlayer · 2026-02-03T13:34:56Z

What Does This Do

This PR introduces a /techdebt skill to try limit the techdebt introduced by LLM and gen AI.
The code tends to duplicate patterns and usually benefits from a refactoring or a complete redo once the working solution is found. The /techdebt asks the tool to review the changes from the branch in order limit this behavior once the changes are ready.

Usage

It's a Claude skill to clean up your branch before committing the PR.
From Claude code, type /techdebt. It will fetch the changes from the branch, and look for the LLM anti-patterns.
If it finds some, it propose to fix them.

You can add some context or ask him to focus on something specific using: /techdebt <custom request here>.
The skill is using a subagent, so it should not pollute your context reviewing the changes.
Once it fixes the issues it found, don't hesitate to run multiple time until it founds nothing to clean up.

Here is an output example:

  Would you like me to fix these issues? I can:
  1. Remove all dead/commented code
  2. Clean up unused fields
  3. Resolve or remove TODO comments (with your guidance on the design decisions)

Motivation

Inspired from Boris Cherny’s thread.

Additional Notes

This skill was defined by Claude itself as recommended. Not sure why the claude code product is not able to apply this recommendation by itself then 🤷

+UPSTREAM=$(git remote -v | grep -E 'DataDog/[^/]+(.git)?\s' | head -1 | awk '{print $1}')
+if [ -z "$UPSTREAM" ]; then
+  echo "No DataDog upstream found, using origin"
+  UPSTREAM="origin"

+echo "Comparing against: $UPSTREAM/master"


I added some tweaks to make sure it use the right reference in case of:

multiple remote

outdated (local) master branch
