Use when designing, implementing, reviewing, testing, or cleaning up feature toggles, feature flags, kill switches, runtime configuration gates, canary controls, staged rollouts, experiments, or temporary compatibility switches in Java enterprise systems. This should trigger for requests such as Design a feature toggle strategy; Review this feature flag; Add a kill switch safely; Test toggle on and off paths; Clean up an expired feature toggle; Plan controlled rollout and rollback behavior.…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Feature Toggles Design Guide Java Enterprise developers through safe feature toggle design and lifecycle management. **This is an interactive SKILL**. **What is covered in this Skill?** - Deciding when a feature toggle is appropriate versus a branch, configuration change, deployment change, or parallel change - Classifying release toggles, operational kill switches, experiment toggles, permission toggles, and migration toggles - Designing typed toggle ownership, defaults, evaluation scope, fallback behavior, observability, and rollback controls - Implementing toggles in Java services without scattering flag checks or creating hidden long-term complexity - Reviewing toggles for release, rollback, security, privacy, concurrency, and maintenance risk - Testing both enabled and disabled paths, configuration failure behavior, rollout rules, and cleanup readiness ## Constraints Use feature toggles as explicit, owned runtime control points rather than hidden conditional complexity. - **MUST** read `references/057-design-feature-toggles.md` before applying feature toggle guidance …

How to install
mdr add jabrena/plinth/057-design-feature-toggles@sha256:5783963496eec7e7The line at the top of this page pins the label v0.19.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
