OMK v2.0.0

OMK 2.0.0 is a declared milestone release. The owner declared the 2.0.0
milestone on 2026-11-14, which the constitution requires before a release may
cross the major boundary (OMK_ALLOW_MAJOR_RELEASE=1). It does not reopen
routine major bumps: later releases go back to patch and minor.

The headline change is that OMK now loads native omk package manifests by
default. Legacy Pi packages still work, but only when you opt in.

Breaking change: native package manifests by default

The default package manifest dialect is now omk. Extensions that import
legacy Pi packages without installing them, and packages that ship only a pi
manifest, no longer load by default. To keep loading them:

  • CLI: --package-manifest-dialect omk+pi
  • SDK: packageManifestDialect: "omk+pi" in the constructor options

The load error names this option, and omk package doctor checks against the
native target by default. See
the OMK 2 migration notes.

Added

  • omk-speak-like-you-eat is a new optional package adapting SLYE 1.6.1: manual
    and automatic plain-language companions, ELI5 and Light tabs, scoped model
    selection, trusted project settings, custom prompts, cancellation and retry.
    Install it with omk install npm:omk-speak-like-you-eat@2.0.0.
  • Extensions can render persisted custom entries with registerEntryRenderer()
    without adding them to the model's context, and extension contexts expose
    session-scoped models.
  • Next-task suggestions (OMK_NEXT_SUGGESTIONS, flag, default off) show a
    complete prompt in the empty editor: a title, then input, verification,
    evidence and result sections. Tab inserts exactly the displayed text.
  • Editor.setInlineSuggestion() in omk-tui renders a dim suffix at the end of
    the document.

Changed

  • Automatic skill loads and provider-harness grants score each clause of a
    request that needs several capabilities, and grant one skill per clause before
    a second skill for the same clause, still at most three. Single-clause
    requests rank as before.
  • omk-ai pins @anthropic-ai/sdk 0.92.0. Anthropic requests ignore the SDK's
    new ANTHROPIC_CUSTOM_HEADERS variable, and the root declarations no longer
    load @google/genai.

Fixed

  • A receipt-reading critic, visual-QA or document lane waits only for the
    producers whose receipts it reads.

Rust core status

This release contains stage K0 of the Rust core plan (spec 120): the
native/omk-contract crate defines the session JSONL, public RPC and
extension-host wire types, and the Node core's compatibility table and protocol
type declarations are generated from it. Nothing in production calls a Rust
crate. Node still runs the agent, extensions and SDK, and there is no Rust
runtime to select. This release makes no speed, memory or solve-rate claim; see
the Rust core plan.

Packages

All eight public packages move to 2.0.0 in lockstep: open-multi-agent-kit,
omk-ai, omk-agent-core, omk-tui, omk-protocol, omk-adaptorch-wpl,
omk-book-to-skill and omk-speak-like-you-eat. Full details are in each
package's CHANGELOG.md.
