Agent UI v0.4.4

Agent UI v0.4.2

Agent UI v0.4.2

Agent UI v0.4.2 adds public ecosystem exposure across the Agent standards family. Each standard now links to the other published standards and documents future standard candidates.

Highlights

• Adds an Agent standards ecosystem page under reference/agent-ecosystem.
• Links Agent Knowledge, Agent UI, Agent Runtime, and Agent Evidence from the public docs.
• Adds English and Simplified Chinese ecosystem pages.
• Adds ecosystem links to llms.txt and llms-full.txt.
• Updates version snapshots and package metadata.

Validation

• Forbidden local-coupling scan

Agent UI v0.4.1

Agent UI v0.4.1

Agent UI v0.4.1 adds LLM-friendly documentation entrypoints. It publishes concise and full-context markdown files at the repository root and the documentation site root so AI clients can discover the standard without crawling the whole site.

Highlights

• Adds llms.txt as the concise LLM navigation index.
• Adds llms-full.txt as a concatenated English core documentation file with source URLs.
• Adds compatible llm.txt and llm-full.txt aliases.
• Publishes the same files through docs/public/ so GitHub Pages serves them from the site root.
• Includes the LLM entrypoint files in the package manifest.

Validation

• npm run build
• VITEPRESS_BASE="/agentui/" npm run build
• npm pack --dry-run
• Root/public LLM file consistency checks

Agent UI v0.4.0

Agent UI v0.4.0

Agent UI v0.4.0 makes Artifact Workspace a first-class surface in the standard. The release keeps Artifact inside Agent UI, but draws a hard boundary: Agent UI owns artifact interaction semantics; artifact services own content, storage, version persistence, export bytes, and write authority; evidence systems own verification, replay, and review facts.

Highlights

• Expands the former artifact canvas guidance into Artifact Workspace.
• Defines the artifact workspace interaction contract: artifact facts, cards, preview, edit/canvas, version rail, diff/review, export/handoff, source links, and evidence links.
• Adds specific artifact event classes: artifact.created, artifact.updated, artifact.preview.ready, artifact.version.created, artifact.diff.ready, artifact.export.started, artifact.export.completed, artifact.failed, and artifact.deleted.
• Keeps artifact.changed as a collapsed adapter event for clients that cannot emit the finer-grained artifact lifecycle yet.
• Updates runtime projection, runtime standard, message parts, quickstart, examples, glossary, acceptance scenarios, and research references around artifact-first delivery.

Compatibility

• Existing v0.2/v0.3 clients can keep projecting artifact.changed while they migrate to the new specific artifact events.
• The release does not turn Agent UI into an artifact storage protocol.
• Implementors should expose stable artifact references and interaction state instead of copying full artifact content into the conversation transcript.

Research Inputs

• Claude Artifacts: substantial standalone content belongs in a dedicated artifact area rather than the main conversation stream.
• Vercel AI SDK UIMessage: UI rendering should use typed message parts such as files, sources, tools, data, text, and reasoning.
• assistant-ui: clients should render attachments, message parts, and tool UI through runtime adapters and typed renderers.
• OpenAI Apps SDK: rich UI belongs behind structured tool/component boundaries, with component-only metadata kept out of the model-visible transcript.

Validation

• npm run build
• VITEPRESS_BASE="/agentui/" npm run build
• npm audit --omit=dev
• npm pack --dry-run
• Forbidden-term and project-coupling scan outside generated output.
• Build output checks for Artifact Workspace routes, artifact export events, Mermaid rendering, and corrected GitHub Pages logo path.

Agent UI v0.3.0

Agent UI v0.3.0

Agent UI v0.3.0 reframes the standard around the full agent product ecosystem. It removes the misleading impression that Agent UI is mainly a boundary with two adjacent standards and makes tools, skills/workflows, context, artifacts, evidence, permissions, sessions, runtimes, models, and design systems first-class neighboring systems.

Highlights

• Adds a new Ecosystem boundaries reference page under /reference/ecosystem-boundaries.
• Defines Agent UI's responsibility across runtimes, model/provider streams, tools/connectors, skills/workflows, memory/knowledge/context stores, artifact services, evidence/observability, permission/policy, session/storage, and design systems.
• Removes the old Skills/Knowledge-centered boundary page source files from the documentation tree.
• Updates the README, overview, definition, and specification pages to describe Agent UI as the projection layer from adjacent system facts to user interaction semantics.
• Keeps the runtime-first v0.2 surfaces and contracts intact: event projection, message parts, tool UI, HITL, artifacts/canvas, timeline/evidence, sessions/tabs, hydration, queue/steer, and performance budgets.

Compatibility

• v0.3.0 does not change the runtime event schema introduced in v0.2.0.
• Existing v0.2.x implementors should treat this as a scope and documentation correction.
• New readers should start from runtime facts and ecosystem boundaries rather than from any single adjacent standard.

Validation

• npm run build
• VITEPRESS_BASE="/agentui/" npm run build
• npm pack --dry-run
• npm audit --omit=dev
• Project-coupling and forbidden-term scan outside generated output.
• Build output checks for Mermaid rendering, corrected logo path, new ecosystem-boundary route, and removal of the old boundary route.
