- Migrated all wire protocol, schema definitions, and tools validation from Zod to ArkType across multiple packages.
- Updated extension runtimes, custom tools loader, and TypeBox compatibility shim to expose and use ArkType instances.
- Added a comprehensive ArkType migration guide, validation parity tests, and helper utilities.
- Removed redundant PDF asset routing and parsing implementations from the read tool.
- Replaced Bun.sleep and wall-clock timing with fake timers (vi.useFakeTimers), release gates, and deterministic polling across 15+ test files to eliminate flakiness and improve speed.
- Consolidated per-test fixture setup into beforeAll/afterAll lifecycle hooks across 20+ test files, reducing redundant initialization and improving test performance by reusing shared immutable fixtures.
- Stubbed network calls in ModelRegistry and test discovery to prevent unintended outbound requests during test execution.
- Replaced subprocess-based test coordination (file markers, Bun.sleep polling) with in-memory fakes (FakeWebSocket, FakeLspServer, VirtualClock) for deterministic, fast test execution.
InteractiveMode.refreshSlashCommandState() built the autocomplete
provider from builtins, hook/custom/skill commands, and file-based
slash commands but never read session.promptTemplates, so templates
loaded from cwd/.omp/prompts/ and the agent prompts directory expanded
when typed manually yet never appeared in the / picker. Pass them
through alongside file commands; filter out templates whose names
collide with an existing command so the picker mirrors the runtime
expansion order (expandSlashCommand precedes expandPromptTemplate in
AgentSession.prompt).
Added a regression test that constructs InteractiveMode with a session
that carries a prompt template, spies on editor.setAutocompleteProvider,
and asserts the captured provider returns the template for both the
empty / menu and a fuzzy /rev prefix, plus the collision-dedup contract
against the builtin /exit.
