ReAct application tools
domain.ts validates task scope, native actions, CSV arithmetic and reports. adapters.ts registers job status/logs, runbook search, recovery and API/browser result tools. service.ts provides a real local HTTP/SQLite job environment with restartable scenarios. These are application integrations, not Core business APIs.
createTask binds immutable requests and controller policy. ReactAdapters.tools are registered with the public Interaction Worker. react_authorize, react_verify and react_publish are controller-only tools excluded from the model catalog. Tool schemas are supplied to the public SAMPLE node; the Loop validates entire action batches before dispatch.
The service owns service.sqlite; the Agent uses Redis Context and separate SQLite Memory via storage. Runbook evidence comes from a real local document. Browser operations reuse operations/sdk.ts and its Playwright configuration. Install Chromium before using delivery: "browser"; browser imports are lazy. API-only tasks require no browser installation.
Recovery is scoped to the requested job and permitted transient error, requires log/runbook evidence, checks a task idempotency key before sending POST and uses a server-side transaction. Unknown results are returned as observations. The demo uses a 400 ms HTTP deadline to make delayed-response scenarios reproducible; choose a suitable transport timeout in an external-service adapter.
Evidence is immutable and content-addressed. Completion re-reads service state and CSV, checks integer arithmetic and evidence, then issues a verification receipt. Publication checks the receipt plus every successful observation against snapshots. It writes Markdown/JSON idempotently and never performs an implicit retry or sends a message.
Provide authenticated controller identity, origin authorization and per-directory locking in the host. The loopback service is not a production identity system. External tool adapters must implement their own authentication, scoped permissions, cancellation and effect reconciliation. See API details.
