Question 1

What is Flag Sweeper and what problem does it solve?

Accepted Answer

Flag Sweeper is an MCP server that automates the cleanup of feature flags in your codebase. It addresses the technical debt caused by dead flags, branching complexity, bug risks, and performance overhead by replacing flag calls with their final configured values.

Question 2

How does Flag Sweeper automate flag cleanup?

Accepted Answer

It leverages Polyglot Piranha to detect feature flag calls based on patterns defined in a `flags.json` file. It then transforms these calls into their static configured values (e.g., `true` or `false`), allowing compilers to perform dead code elimination.

Question 3

Which programming languages are supported by Flag Sweeper?

Accepted Answer

Flag Sweeper supports a wide range of languages including Go, Java, Python, JavaScript/TypeScript, and C#. Its extensible architecture via Polyglot Piranha's rule system allows for support for even more languages and custom patterns.

Question 4

What are the key benefits of using Flag Sweeper for developers?

Accepted Answer

Using Flag Sweeper significantly reduces technical debt, improves code clarity and maintainability, minimizes bug risks from outdated logic, and enhances application performance by eliminating unnecessary runtime checks and enabling dead code elimination.

Question 5

Can Flag Sweeper integrate with existing feature flag management systems?

Accepted Answer

Currently, flag states are configured via a `flags.json` file. However, Flag Sweeper's future vision includes direct integration with live feature flag systems like LaunchDarkly, Split.io, and Unleash, along with safety analysis for automated, enterprise-grade cleanup workflows.
