Multi-step LLM activity demonstrating @temporalio/tool-registry end-to-end. agenticSession with heartbeat checkpointing, MCP HTTP integration via sidecar, human-in-the-loop via companion workflow, and a testable activity refactor (buildTriageRegistry + TriageDeps). Includes mocha tests using MockProvider with no API key required. Conventions followed: - src/ layout with src/mocha/*.test.ts (per hello-world template) - Standard package.json scripts (build, start, workflow, test, lint, format) - Added to .scripts/list-of-samples.json (alphabetical) - Added to root README API demos / Activity APIs section The dependency on @temporalio/tool-registry currently uses a file: path to the in-development sdk-typescript checkout, since the package isn't published yet. Swap to a version pin once it ships.

Adds a new sample under
tool-registry-incident-triage/demonstrating@temporalio/tool-registryend-to-end.The example includes:
agenticSessionwith heartbeat checkpointing.buildTriageRegistry(alert, session, deps)returning{ registry, getResult }plus aTriageDepsinterface of I/O callables, so unit tests substitute fakes and drive the registry viaMockProvider.Mocha tests in
src/mocha/triage_activity.test.tsuseMockProviderand require no API key or running Temporal server. All 6 tests pass.Conventions followed:
src/layout withsrc/mocha/*.test.ts(perhello-worldtemplate).package.jsonscripts (build,start,workflow,test,lint,format)..scripts/list-of-samples.json(alphabetical).README.mdunder "Activity APIs and design patterns".Known transitional issue: the dependency on
@temporalio/tool-registrycurrently uses afile:path (file:../../sdk-typescript/packages/tool-registry) since the package isn't published yet. The sibling sdk-typescript PR (#2008) recently added apreparescript which causesnpm installto attempt a workspace-wide build that fails on unrelated worker-package issues. Workaround:npm install --ignore-scripts. Will switch to a published version pin once temporalio/sdk-typescript#2008 lands and the package publishes.Cross-references the SDK PR (temporalio/sdk-typescript#2008) which adds the
@temporalio/tool-registrypackage itself.
