RCIP 2.0.3 — React starter and discovery

RCIP 2.0.3 makes the existing React capability runtime easier to find, try, and integrate. Runtime behavior, public APIs, and protocol 1.0 are unchanged.

• Standalone React/TypeScript starter with discovery, current-state reads, input validation, confirmed writes, decline, and cancellation. Copy the directory or download the source-only ZIP below.
• Expanded agentic UI, frontend tools, in-app agent, and browser-use metadata and guidance. External browser agents still need an application-selected bridge; MCP/WebMCP adapters and generic discovery remain future work.
• An llms.txt documentation map and a 71-second captioned walkthrough of the deterministic demo.

The starter pins the already verified npm release 2.0.2 so it is reproducible independently of this release's publication. RCIP 2.0.3 has the same runtime/API behavior. The starter is not a separate npm package.

Validation: package/type/build checks, React 18/19 packed consumers, 25 composed browser scenarios, three site checks, and an isolated install/build/browser check of the standalone starter. GitHub CI also checks Node 20, 22, and 24. The release workflow verifies the exact published npm version after upload.

The video shows a local production build of the reference demo at original interaction speed, with explanatory captions. It uses a deterministic adapter and no AI service, external browser-agent integration, or model benchmark. Captions are burned into the MP4 and available separately as WebVTT. The ZIP contains only the starter's source, lockfile, and license; install dependencies with npm ci.

Existing public monitoring keeps its original expiry: 2026-09-24T21:00:04Z.

RCIP 2.0.2 — React agent discovery and public health checks

RCIP 2.0.2 improves discovery and verifies the package users actually install. Runtime behavior, public APIs, and protocol 1.0 are unchanged.

• Expand React UI-agent, assistant, tool-calling, and function-calling keywords and examples across npm, GitHub, and the documentation.
• Explain RCIP's relationship to MCP and WebMCP explicitly: direct protocol adapters are planned and are not included.
• Add local health:availability and health:regression commands, reused by GitHub Actions.
• Verify exact published versions across React 18.2, 18.3, and 19.1, including imports, TypeScript, builds, and browser discovery/read/write/confirmation behavior.
• Check registry metadata, documentation, demo, sitemap, and page assets; add a seven-day availability schedule with daily regression and automatic expiry.
• Keep monitoring on standard public runners without persistent Actions caches or artifact uploads. Results are recorded in logs and job summaries.

RCIP 2.0.1 — runtime hardening and discoverability

RCIP 2.0.1 strengthens invocation and confirmation behavior while keeping protocol 1.0 and existing public APIs. RCIP now expands to React Capability Interface Protocol; the package remains @binaried/rcip.

• Prevent duplicate execution during asynchronous policy checks and pending confirmation.
• Reject stale bindings, unavailable actions, and changed semantic context before execution.
• Capture requests independently of caller mutation, protect discovery metadata, and clean up expired or cancelled confirmations.
• Release cancelled policy waits without executing late results; publish React bindings only after committed renders.
• Add searchable documentation, complete TypeScript contracts, lifecycle/security guidance, bundle measurements, a Finance case study, and a static interactive demo.
• Validate Node 20/22/24, packed React 18.2/18.3/19.1 consumers, SSR/hydration, and browser behavior. Repair secret-history scanning and update affected build dependencies.

Cancellation remains cooperative and cannot undo completed effects. Backend authorization and write idempotency remain application responsibilities. This release adds no WebMCP adapter.
