+# CommandKit v0.1.0
+
+## Summary
+
+CommandKit's initial release provides a Go library for consistent CLI inspection,
+command syntax, and shared command infrastructure. Applications register their
+own domain commands alongside CommandKit's standard inspection families.
+This release is a source-only Go module.
+
+## Features
+
+- An instance-owned command registry with composable groups, typed flag and
+  operand bindings, and explicit presence tracking for empty, false, and zero
+  values. Each invocation has fresh parsing state.
+- A root public `commandkit` facade with Cobra-backed routing and parsing behind
+  an internal adapter. Applications supply context and streams and retain their
+  startup, acquisition, domain behavior, and process-exit decisions.
+- Metadata-driven help and version reporting. Version output defaults to the
+  application identity and can explicitly select the embedded CommandKit identity.
+- Configuration scope discovery, validation, native effective YAML display,
+  source inventory, and path explanation through application-supplied providers
+  and ConfigKit adapters. Aggregate effective display emits a YAML document per
+  selected scope with scope labels.
+- Independent registration of PromptKit engine configuration inspection and
+  optional named prompt/profile inspection, with text and YAML definition reports.
+- Invocation outcomes that preserve application domain classifications and
+  supported error identity, with diagnostic and report-delivery failure reporting.
+- Reused command and scope metadata, indexed command lookup, invocation-local
+  backend sessions, requested-format report rendering, and fewer YAML framing
+  allocations.
+
+See the [CLI reference](https://gitea.maximumdirect.net/eric/CommandKit/src/tag/v0.1.0/docs/cli.md)
+for command contracts and the [consumer guide](https://gitea.maximumdirect.net/eric/CommandKit/src/tag/v0.1.0/docs/consumers/guide.md)
+for integration and maintained examples. Semantic configuration comparison and
+PromptKit catalog listing remain deferred.
+
+## Requirements and adoption
+
+**Go 1.26.0 or newer is required.** During development, the declared minimum
+increased from Go 1.25.5 to 1.26.0 with the adoption of ReleaseKit v0.3.0.
+ReleaseKit is a maintainer tool dependency in the root module graph, so its Go
+requirement also applies to library consumers; production packages do not import
+ReleaseKit. Consumers using Go 1.25 must upgrade their toolchain before adopting
+v0.1.0. The selected maintainer release toolchain is Go 1.26.8, distinct from the
+consumer minimum.
+
+Select the released module version with:
+
+```sh
+go get gitea.maximumdirect.net/eric/CommandKit@v0.1.0
+```
+
+Applications migrating from their own CLI implementations should align standard
+command paths and syntax with CommandKit, then update operator documentation and
+subprocess callers for those intentional changes. Application-specific commands
+remain application-owned. Compatibility for subsequent releases follows the
+[release policy](https://gitea.maximumdirect.net/eric/CommandKit/src/tag/v0.1.0/docs/policy/release.md).
