feature-flagging SKILL.md skillA
feature-flagging from rampstackco/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rampstackco/claude-skills/feature-flagging@git:20260810.e5bc675Pins git:20260810.e5bc675 in mdr.lock. Pin the fingerprint instead.

Operational discipline for feature flags as production infrastructure. Flag types, naming, targeting rules, rollout strategy, lifecycle, governance, stale flag management, and the technical debt patterns that bite teams who weren't deliberate about it.
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 Flagging A senior engineer's playbook for using feature flags well, not just frequently. Feature flags are infrastructure. Treated as such, they enable kill switches, gradual rollouts, A/B experiments, permission gates, and operational toggles without redeploys. Treated casually, they become the largest accumulating technical debt in your codebase: thousands of dead flags, conflicting evaluation logic, brittle targeting, and a permission surface no one fully understands. This skill is the discipline that prevents the second outcome. It assumes you have a feature flag platform (LaunchDarkly, Flagsmith, Split.io, VWO FME, GrowthBook, Statsig, PostHog, Optimizely; the platform does not matter for the principles). It assumes your engineering team can implement targeting rules and SDK integration. The hard part is the operational discipline, and that is what is here. When to use this skill: any time you are about to introduce a flag, modify a flag, audit existing flags, or design a flag-related governance policy. --- ## What this skill is for …

How to install
mdr add rampstackco/claude-skills/feature-flagging@sha256:597cb210221fb090The line at the top of this page pins the label git:20260810.e5bc675, 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.
