It helps engineering teams systematically retire feature flags, reducing codebase complexity and technical debt. Built with [Lamatic.ai](https://lamatic.ai). + +## Purpose +The goal of this agent system is to solve the problem of feature flag accumulation — a pervasive form of technical debt where teams add flags for safe releases but never clean them up. Over time, stale flags clutter the codebase, confuse new developers, increase cognitive load, and create hidden failure modes. + +The system centralizes flag discovery and lifecycle analysis into two deployed Lamatic flows: first scanning source code for all flag patterns across major providers (LaunchDarkly, ConfigCat, Split, Unleash, Growthbook, custom/enum, and environment-variable-based flags), then evaluating each flag's status and producing a structured cleanup plan with removal risk, effort estimates, and deprecation timelines. This keeps the analysis logic in Lamatic Studio where prompts and model selection can be iterated on, while the calling application stays thin. + +## Flows + +### `flag-scan` +- **Flow ID / Env key mapping:** Flow ID → `flag-scan` (env key: `LAMATIC_FLAG_SCAN_FLOW_ID`) +- **Trigger:** API request via GraphQL trigger node (`graphqlNode`).
