Goal

Make third-party extensions safe and practical to build without relying on private internals.

Scope

  • Define versioned extension protocols, capability negotiation, lifecycle hooks, and error behavior.
  • Provide a public testkit with fixtures for discovery, isolation, failure, and compatibility.
  • Add a reference extension and a compatibility matrix.
  • Document trust boundaries, permission expectations, and optional dependency behavior.
  • Decide whether the SDK is part of base-cli or a separately versioned package.

Acceptance criteria

  • An external contributor can build and test an extension using public APIs only.
  • Incompatible extensions fail clearly without taking down unrelated extensions.
  • SDK compatibility is tested across supported Python and Click/Typer versions.
  • Security and lifecycle guarantees are documented.

    2026-09-12 repository review refresh

    The extension SDK/testkit remains useful, but new allowlist-identity defect #340 should be repaired independently before broadening third-party adoption. Include discovery collisions, lazy loading, failure isolation and instance-owned contracts in the public consumer testkit. The existing protocols and API-version negotiation are strengths to preserve.

    Validated against current main (7faf347a5b90969e169c88f3ac18e7202d142dd0). This review files and scopes work; it does not claim implementation or authorize release/admin changes.
