+# Should I use base-cli?
+
+## Status and compatibility
+
+As of this guide, the newest published Base-CLI release is `0.4.3`; the package
+is pre-1.0 and classified as Beta. The demo currently tests the released
+`>=0.4.3,<0.5` line. This is not a promise that every future pre-1.0 minor line
+is compatible: Base-CLI's published policy treats patch releases as compatible
+and allows a minor release before 1.0 to be a compatibility boundary. Read the
+[API stability policy](https://github.com/basefoundry/base-cli/blob/main/docs/api-stability.md)
+and [migration notes](https://github.com/basefoundry/base-cli/blob/main/docs/migrations.md)
+when changing the dependency range. The demo's lockfile records a reproducible
+resolved environment; library consumers should choose a range that matches
+their own upgrade policy.
+
+Base-CLI does not replace Click or Typer. It composes with their command
+surfaces to provide shared invocation lifecycle behavior; the application
+continues to own its commands, configuration policy, and domain logic.
+
+## Good fit
+
+Base-CLI is worth evaluating when a team ships a Python CLI that has several
+commands or consumers and needs a consistent operational contract across them:
+
+- both interactive users and scripts need predictable output and exit status;
+- operators need repeatable logging, diagnostics, temporary paths, and cleanup;
+- commands benefit from shared dry-run, configuration, or lifecycle behavior;
+- the team is willing to track the framework's supported release line and test
+  upgrades.
+
+The [Northstar walkthrough](learning-path.md) shows the smallest examples in
+this repository. The [framework boundary](../README.md#framework-boundary)
+explains which decisions remain consumer-owned.
+
+## Poor fit
+
+Keep a simpler stack when a program is a one-off script, has one small command,
+does not need machine-facing output or shared lifecycle behavior, or has a
+policy against adding a framework dependency. Base-CLI is also not a fit for a
+non-Python application, and a team that requires a frozen 1.0 API today should
+account for its pre-1.0 status before adopting it.
+
+## What adoption costs
+
+You add `base-cli` as a runtime dependency and use its lifecycle/context and
+public integration boundary. The application still owns its parser commands
+and domain policy, but its entry point and tests now follow Base-CLI's
+invocation model. The consuming team must maintain its supported dependency
+range, lock or otherwise reproduce the environment, and run compatibility
+tests when upgrading. Before 1.0, a minor framework upgrade may require a
+compatibility review or code changes; this demo's `<0.5` bound deliberately
+does not follow a future 0.5 line automatically.
+
+## Alternatives and trade-offs
+
+| Choice | What it gives you | What you take on |
+| --- | --- | --- |
+| `argparse` | A command-line parser in Python's standard library, with no third-party parser dependency. | Your application composes the command lifecycle, shared policy, and machine-output contract it needs. |
+| Click | A composable command/group/option system with help and parsing behavior. | You choose and maintain the cross-command lifecycle, runtime state, logging, and output conventions. |
+| Typer | A Click-based interface that derives command parameters from Python type hints. | You still decide whether to add a lifecycle layer and how to keep its operational behavior consistent. |
+| Base-CLI with Click or Typer | A shared lifecycle and documented automation/output boundary around a familiar parser. | One more dependency, an integration model to learn, and compatibility work as the framework evolves. |
