Liveblocks AI Presence extends the existing Liveblocks real-time collaboration SDK to let AI agents appear as named, cursored participants alongside human users in web apps. Developers wire it in through a single React hook with no backend changes required. It treats AI as a first-class presence participant rather than a background process, making agent activity visible and legible to human collaborators.

Skrun is an open-source tool that wraps agentic skills — the discrete, reusable capabilities you build for AI agents (web search, data extraction, file transformation, API calls) — into deployable REST APIs with a single command. The idea is that skills you build for one agent context shouldn't be locked to that agent's runtime. With Skrun, you define a skill once with a standard function signature, and get a hosted endpoint with automatic request validation, retry logic, rate limiting, and an OpenAPI spec generated automatically. The project addresses a real architectural tension in the current AI tools ecosystem: agent skills are written in a dozen different formats (LangChain tools, MCP tools, function call JSON, OpenAI tool specs) and are essentially stranded assets — they only work within their specific orchestration framework. Skrun normalizes this by wrapping any skill definition format and exposing it as a framework-agnostic HTTP endpoint that any agent or pipeline can call. This appeared on Hacker News with a small but thoughtful discussion focused on the "skills as microservices" architectural pattern. Critics noted that adding HTTP round-trips to every tool call introduces latency; proponents argued that the composability and reusability benefits outweigh the cost. The early version focuses on stateless skills; stateful/conversational skill deployment is on the roadmap.

The primitive is clean: a React hook that injects an AI agent into Liveblocks' existing presence layer, giving it a cursor, a name, and a selection state — no new backend surface, no second SDK to wrangle. The DX bet is correct: they put the complexity in the abstraction, not in the integration. The moment of truth is a single `useAIPresence` call and your agent has a visible cursor within minutes. You could not replicate this on a weekend — Liveblocks' CRDT sync layer and multiplexed WebSocket infra are the actual hard part, and this just exposes a new participant type on top of it. The specific decision that earns the ship: they didn't add a new API, they extended the existing presence model — that's the right call architecturally.

The framework portability angle is the real value prop — I have dozens of custom tools built for Claude that I can't reuse in other contexts without rebuilding them. If Skrun actually normalizes this cleanly across tool formats, that's a genuine pain solver.

The direct competitor here is 'just log what your AI is doing in a sidebar,' which is what most teams ship today. AI Presence beats that because the presence metaphor maps to user mental models already trained by Figma and Google Docs — a cursor is legible in a way a log entry isn't. The scenario where this breaks is any app where the AI agent operates faster than human perception — a cursor flickering across a document at 200 tokens per second is noise, not signal, and Liveblocks hasn't shown throttling primitives in the demo. What kills this in 12 months: the underlying model providers build native multi-agent orchestration UIs and presence becomes a solved layer in the stack, not a differentiator. To be wrong about that, Liveblocks would need to own enough of the collaboration infra that switching costs make their presence layer the default regardless.

Wrapping every agent skill in an HTTP call is a latency antipattern — a skill that takes 50ms locally becomes 120ms+ through a hosted endpoint with cold starts. For skills called hundreds of times per agent run, this adds up fast. I'd want colocation support before using this in production.

The thesis here is falsifiable: by 2027, human-AI collaborative interfaces will require agents to express intent spatially, not just textually, because human coordination evolved around physical co-presence cues — gaze, gesture, position. If that's true, AI Presence is infrastructure, not a feature. The dependency is that AI agents remain slow enough relative to human attention that cursor metaphors remain meaningful; if agents complete work in under 500ms, the presence layer has nothing useful to show. The second-order effect nobody is talking about: this normalizes AI agents as social participants in software, not background workers, which shifts how users attribute responsibility and trust in collaborative outputs. Liveblocks is riding the multi-agent coordination trend and they are early — most teams haven't shipped a single agentic collaborator, let alone needed to display one. The future state where this is infrastructure: any SaaS with a collaborative canvas runs AI presence the way they run user avatars today.

Skills-as-services is the right architectural direction as agent ecosystems mature. The future is marketplaces of composable agent capabilities that any orchestrator can call — Skrun is early infrastructure for that world.

The job-to-be-done is singular and clear: make AI agent activity legible to human collaborators without building a custom observability layer. Onboarding survives the two-minute test if you're already on Liveblocks — the hook drops in and the agent appears; if you're not on Liveblocks, you're onboarding to an entire collaboration platform first, which is a different product decision. The completeness gap is real: this ships the presence primitive but not the interaction surface — users can see the AI cursor but the blog post doesn't address how users interrupt, redirect, or acknowledge agent actions, which means teams still have to build that layer themselves. The product has a clear opinion — agents are collaborators, not tools — and that opinion is the right one. Ship, but with the caveat that this is a primitive, not a complete human-AI collaboration solution, and teams should scope their expectations accordingly.

Too deep in infrastructure for my workflow, but the auto-generated OpenAPI spec is a nice touch for anyone who needs to share custom skills with a team without writing documentation manually.
