Dimensions

Interface surface 4 exemplary [library] An API reference is generated from the code (autodoc, mkdocstrings, typedoc, …).

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

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

desktop ladder · level 1

  • ✓ L1 Launchable by other programs with input: command-line arguments, a URL scheme or file associations. packages/desktop/src/main/cli/index.ts 1 matchpackages/desktop/src/main/cli/parser.ts 1 match
  • ✗ L2 An automation interface: AppleScript, App Intents/Shortcuts, D-Bus, COM, IPC commands, or a local API. no automation interface
  • ✓ L3 Its functions run without the GUI (a headless/batch mode or a companion CLI). packages/desktop/playwright.config.ts 1 match
  • ✗ 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). 57 semver tags, latest v0.21.2
  • ✗ L2 A changelog exists and marks breaking changes. no changelog
  • ✗ L3 A deprecation mechanism is used in code (warnings, @deprecated, Deprecation/Sunset headers) or the API is versioned. no deprecation mechanism or API versioning
  • ✓ 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 3 solid [library] No output or log statement includes a credential.

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

  • next: [library] L4 Several profiles or scoped credentials per target. (no credential profiles)
  • next: [desktop] 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 2 partial [desktop] In headless mode, data goes to stdout and diagnostics to stderr.

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

  • next: [library] L1 Errors are specific exception types, and library code never calls sys.exit. (no exception classes)
  • next: [desktop] L3 Documented exit statuses distinguish error classes, and headless output is machine-readable (JSON). (exit statuses aren't documented)

Embeddability 3 solid [desktop] 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?

  • next: [library] L3 Published to a public registry, with at most 10 runtime dependencies. (not published to a registry)
  • next: [desktop] L4 Settings can be managed without the GUI: documented environment variables or config file, macOS defaults/MDM profiles, or Windows policies. (settings only change through the GUI)

desktop ladder · level 3

  • ✓ L1 Buildable from source with documented steps (a README with commands). README.md

Extensibility 0 absent Not yet: Internal seams: a registry, registration function or plugin manager.

Can behaviour be added without modifying the code?

  • next: L1 Internal seams: a registry, registration function or plugin manager. (no registry or registration function)

all ladder · level 0

  • ✗ L1 Internal seams: a registry, registration function or plugin manager. no registry or registration function
  • ✗ 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 3 solid [desktop] Crashes are reported (Sentry, Crashpad/Breakpad, Crashlytics, MetricKit).

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

  • next: [library] L3 Optional metrics or tracing hooks. (no metrics or tracing hooks)
  • next: [desktop] L4 Tracing or metrics (OpenTelemetry). (no tracing)

  • ✗ L4 OpenTelemetry instrumentation available. no OpenTelemetry instrumentation
Change legibility 2 partial CI runs the tests; applications pin dependencies (libraries and zero-dependency projects are exempt).

Can an agent change it safely with limited context?

  • next: L3 At least 90% of modules fit 32k tokens and no file exceeds 12k; test/source token ratio at least 0.3; at least 70% of the code is typed. (99% of modules fit 32k tokens; 6 files over 12k)

Classic COCOMO vs neosloc value

Classic COCOMO (sloccount)

81.32 KSLOC → 243.2 person-months over 20.2 months.

$2.7M

The effort to write it by hand, as COCOMO priced it in 1981.

neosloc value (neoCOCOMO)

Reproduce with agents: 32.0 PM (×0.13 of classic; 93% of behaviour captured by tests, contract and docs).

Rediscover uncaptured history: 2.2 PM (1023 fixes in 2246 commits by 217 authors).

× leverage 1.03 (integrability) × obsolescence 0.95.

What survives

14% of the classic figure

6% of the replacement cost lives only in code and history.
