name: feature-flags description: Use when implementing or debugging code that uses @suaveplan/feature-flags: Provider-agnostic feature flag evaluation with typed flag values, strategy chains, and deterministic bucketing.

@suaveplan/feature-flags

Provider-agnostic feature flag evaluation engine for controlling feature rollout without code deploys. The package ships a FlagManager high-level façade, a FlagRegistry backed by any pluggable FlagProvider, and an Evaluator strategy chain. Five composable strategies cover the full rollout playbook: PercentageStrategy (deterministic FNV-1a bucketing for consistent user cohorts), UserTargetStrategy (allowlist), AttributeStrategy (10 comparison operators for segment targeting), ScheduleStrategy (time-window gating), and CompositeStrategy (AND/OR combinator). Built-in providers include MemoryProvider and JsonProvider for file-based flag definitions. Evaluation priority is: flag disabled → in-process override → first matching strategy → default value. This package is for runtime flag evaluation only — it is not a flag management UI or remote config service.

When to use this skill

• Implementing or debugging code that imports @suaveplan/feature-flags.
• The task touches: see package README.
• You need API guidance for this package's exports.

Quick reference

import { /* see API Reference below */ } from "@suaveplan/feature-flags";

Dependencies

Workspace dependencies: @suaveplan/error, @suaveplan/events, @suaveplan/logger, @suaveplan/types

Where to read more

This skill is intentionally short. The package's own documentation is the authoritative source — read these in order:

1. packages/platform/feature-flags/README.md — overview, install, quick-start, module index
2. packages/platform/feature-flags/src/**/*.md — co-located docs per implementation file (Purpose, Features, Basic + Advanced examples, full API reference, Implementation notes — all packages ship ≥200 words per module)
3. packages/platform/feature-flags/package.json exports map — every subpath you can import from

When the user asks an API question, read the relevant co-located .md first; do not answer from training-data memory.
