Technical debt reduction in small pull requests

Pay down debt even when it never wins the sprint

Technical debt is a common reason engineers lose time, and it keeps losing to the next feature. Agents find the debt that slows your team most, rank it by churn and complexity, and pay it down in small pull requests designed to preserve behavior, pinned by tests.

The debt map

Focus cleanup on frequently modified modules

Debt in code nobody touches can wait. Debt in the module your team changes every week costs you on every ticket. The agent ranks every module by churn, complexity, duplication, and bug history, so the first pull requests go where the debt hurts most.

ChurnHow often a file changes. Debt in code nobody touches can wait.
ComplexityLength, nesting, and branches. The harder to read, the slower every change.
DuplicationThe same rule in several places, so one fix becomes four.
Bug historyFiles that keep coming back in incident and bug reports.

One refactor, small steps

Plan the refactor once and review each step

The refactor is planned once and delivered as a staircase of small pull requests. Each step changes structure and is designed to preserve behavior, pinned by tests, and main stays green between every one of them. No long-lived branch, no half-moved codebase.

  1. 01Tests firstBefore structure changes, the agent pins today’s behavior with tests.
  2. 02One step, one pull requestEach step is small, focused, and leaves main green.
  3. 03Next step after mergeThe following step starts only when the previous one is merged.

Dead code

Check unused code before removing it

Old feature flags, files nothing calls, and logic copied into four places stay because nobody is sure they are safe to remove. The agent checks for references, reflection, config loading, and callers, removes them in small batches, and leaves anything uncertain with its owner.

Frequently asked questions

How does BoldCreate decide which technical debt to pay down first?
The agent ranks every module by churn, complexity, duplication, and bug history, so the first pull requests pay back the most.
Will technical debt reduction change how our app behaves?
Each refactor step is designed to preserve behavior, pinned by tests: before structure changes, the agent pins today’s behavior with tests, and main stays green between steps. Your team reviews each pull request before it merges.
How are big refactors delivered?
As a staircase of small pull requests, each small and focused. The next step starts only when the previous one is merged.
How does the agent remove dead code safely?
It checks for references, reflection, config loading, and external callers, and the tests must stay green. Anything it can’t confirm is unused goes to its owner as a question, not a deletion.
