Dimensions

Interface surface 1 ad hoc Launchable by other programs with input: command-line arguments, a URL scheme or file associations.

Can another program use it through a documented, machine-readable surface?

  • next: L2 An automation interface: AppleScript, App Intents/Shortcuts, D-Bus, COM, IPC commands, or a local API. (no automation interface)

  • ✗ L4 The automation interface is specified machine-readably (an AppleScript sdef, D-Bus introspection XML, App Intents, an OpenAPI spec, MCP). no machine-readable automation contract
Contract stability 1 ad hoc Releases are versioned (semver tags or versioned changelog sections).

Can integrators rely on it not changing under them?

  • next: L2 A changelog exists and marks breaking changes. (no changelog)

all ladder · level 1

  • ✓ L1 Releases are versioned (semver tags or versioned changelog sections). 359 semver tags, latest v3.0.21

  • ✓ L4 Across tagged releases, no OpenAPI operation, CLI option or __all__ symbol was removed without first being deprecated. 20 tagged releases compared
Events n/a Not applicable: no service and no long-running CLI mode (batch CLIs, libraries and desktop apps have no events).

Can others react to state changes without polling?

Identity 1 ad hoc Credentials are kept in the OS credential store (Keychain, Credential Manager, Secret Service), not in plain files.

Can a machine act with its own revocable, least-privilege identity?

  • next: L2 Automation and headless runs can authenticate without the GUI (credentials from the environment). (only the GUI can authenticate)

  • ✓ L3 No output or log statement includes a credential. no credential in print/log statements
  • ✗ L4 Several profiles or scoped credentials per target. no credential profiles
Data portability n/a Not applicable: owns no persistent data.

Can its data get in and out, in bulk, in open formats, with an explicit schema?

Agent ergonomics 0 absent Not yet: In headless mode, failures end with a non-zero exit status instead of a dialog.

Can an automated caller use it without guessing, and recover from failure?

  • next: L1 In headless mode, failures end with a non-zero exit status instead of a dialog. (no headless mode for automated callers)

  • ✗ L2 In headless mode, data goes to stdout and diagnostics to stderr. no headless mode for automated callers
  • ✗ L3 Documented exit statuses distinguish error classes, and headless output is machine-readable (JSON). no headless mode for automated callers
  • ✗ L4 Dry-run for side-effecting operations, and agent docs. no headless mode for automated callers
Embeddability 3 solid Distributed for unattended installation: a package manager (Homebrew cask, winget, Chocolatey, Flathub, Snap) or release artifacts built in CI.

Can another system run and compose it without a human?

  • ✗ L2 The docs show how to add behaviour through those seams (even in-tree). no registration functions to document
  • ✗ L3 Out-of-tree extensions are discovered (entry points, a plugin directory, configuration) without editing the package. extensions must be added inside the package
  • ✗ L4 The extension API is versioned, has lifecycle hooks, and has example extensions. the extension API isn't versioned
Observability 0 absent Not yet: Writes logs through a standard logger (os_log/Logger, electron-log, logging, Qt categories).

Can an operator, or an orchestrating agent, tell whether it works and why not?

  • next: L1 Writes logs through a standard logger (os_log/Logger, electron-log, logging, Qt categories). (no standard logging)
