    Feature Flag Retirement Auditor

    Example session with this skill installed

    Audit the retirement of checkout_v2. Production defaults to true and the web dashboard reports 100% rollout. The server registry contains the flag, an admin service is the only known writer, and both checkout branches still exist. Older mobile versions evaluate the flag locally. Evaluation caches have a five-minute TTL. A revenue dashboard groups by the flag variant. Rollback after deleting the configuration has not been defined.

    • Compiled the feature flag retirement

    Verdict — STAGED-RETIREMENT

    The terminal branch is the enabled checkout path, but retirement is not ready. The visible web cohort has converged while old mobile evaluation, analytics continuity, and post-removal rollback remain unresolved.

    Flag identity

    Canonical key: checkout_v2. Known definition: server registry. Known writer: admin service. Production default: true. Terminal behavior: enabled branch. Aliases and environment-specific variants were not supplied and remain an explicit search requirement.

    Staged retirement plan

    1. Resolve aliases and the oldest supported mobile evaluator.
    2. Segment convergence by app version, tenant, region, and offline-client behavior.
    3. Freeze the terminal value and stop all writes.
    4. Wait through cache expiry and verify no cohort changes branch.
    5. Remove runtime evaluations while keeping an emergency code rollback.
    6. Delete the disabled branch and update tests.
    7. Migrate dashboards away from the variant dimension without breaking historical comparisons.
    8. Update documentation and remove remote configuration last.

    Discriminating tests

    Replay the oldest supported mobile client, test evaluation during and after cache expiry, verify dashboard continuity, and drill rollback using a release artifact that does not depend on the deleted flag record.

    Validator

    All ten coverage domains are present and the record passes the bundled structural validator. No flag, cache, application, dashboard, or production environment was modified.

    About this skill

    A flag is distributed state, not one conditional

    Definitions, writers, readers, defaults, remote evaluation, old clients, cohorts, caches, analytics, tests, documentation, and rollback can keep a feature flag alive after a rollout appears complete.

    Feature Flag Retirement Auditor resolves one canonical identity, inventories ten lifecycle domains, proves cohort convergence, selects the terminal branch, and sequences a reversible cleanup. Configuration is removed only after evaluations, dead behavior, analytics, tests, documentation, and recovery have been reconciled.

    Built for platform, product-infrastructure, mobile, and release engineers cleaning up rollout flags, experiment switches, operational toggles, and kill switches. It profiles the real flag SDK, evaluation location, client lifecycle, analytics naming, cache policy, tests, and deployment model.

    The package includes full Skill source, a ten-domain coverage method, worked checkout example, deterministic validator, mutation tests, and a six-page Buyer Guide PDF.

    Boundaries

    It does not flip flags, edit code, deploy, or infer that a platform-wide percentage represents every tenant, region, version, or offline client.
