Use when the app needs runtime feature toggles (gradual rollout, A/B tests, beta programs, kill switches, per-tenant or per-user targeting) with Pragmatic.FeatureFlags.
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
# Pragmatic Use Feature Flags **Covers:** Feature flags with Pragmatic.FeatureFlags from NuGet: context-aware evaluation, targeting rules, percentage rollout with deterministic per-user/tenant bucketing, and change watching. A deterministic evaluation engine: define flags with targeting rules, evaluate them against a context. The same user/tenant always resolves the same way (stable bucketing), with no flapping between requests. ## When to use - Percentage rollout, beta cohorts, kill switches, A/B tests. - Toggles that depend on user/tenant/environment, not a single global on/off. ## Packages ```xml <PackageReference Include="Pragmatic.FeatureFlags" Version="1.0.0-alpha.3" /> ``` ## Core pattern Rules are built with the static factories on `FeatureFlagRule`; there is no `PercentageRule` / `TenantRule` type. They are evaluated **in order, first match wins**; if none matches, the flag's global `Enabled` applies. ```csharp using Pragmatic.FeatureFlags; using Pragmatic.FeatureFlags.Providers; // register the in-memory store (see "Registration" below for what the host already does) services.AddPragmaticFeatureFlags(); …

How to install
mdr add pragmatic-design/pragmatic.design/pragmatic-use-feature-flags@sha256:78b62da17995ac0bThe line at the top of this page pins the label git:20261017.dc88d60, 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.
