# Agents SDK v0.14.0 lands: Agent Skills, messengers, and a lot more!

Hey there, it's me, Shiichan! Today I found an update that makes building AI agents a whole lot more fun. Let me walk you through it.

## What was announced?

On Cloudflare's Changelog, [Agents SDK](https://github.com/cloudflare/agents) v0.14.0 went live. It's a packed release: Agent Skills, messenger integration, scheduled tasks, Workflows integration, and hardened chat recovery all landed at once.

The main topics look like this:

- Agent Skills (experimental)
- Messengers (Telegram first)
- Scheduled tasks
- Think Workflows
- Production hardening for durable chat recovery
- MCP transport improvements

## The story so far

Until now, giving an agent knowledge or skills usually meant cramming everything into the prompt, which kept ballooning. Chat integration was fiddly too — you handled webhooks yourself and nursed streams back to life when they stalled mid-turn.

## What changes

v0.14.0 shifts a lot of that "you had to build it yourself" work over to the SDK.

With Agent Skills, you can load an on-demand catalog of instructions, so you call a skill only when you need it instead of fattening the prompt. Skills load from bundled directories, R2, or manifests, and expose `activate_skill`, `read_skill_resource`, and optionally `run_skill_script` tools. Sources that fail to load are skipped with a warning — a kind design.

Messengers connect a Think agent directly to chat platforms. Telegram is the first provider, and it handles webhook routing, conversation management, durable reply delivery, and streamed responses for you. See the [Chat agents docs](https://developers.cloudflare.com/agents/communication-channels/chat/chat-agents/) for the details.

## Dive Deep

- Scheduled tasks: write timezone-aware recurring prompts declaratively, like "every week on monday at 09:00" or "every day at 08:00 in Europe/London." It's backed by idempotent submissions that re-arm after each run.
- Think Workflows: with `ThinkWorkflow` and `step.prompt()`, you can fold model reasoning steps into Cloudflare Workflows. It supports typed structured output via Zod schemas, long waits, and approval gates with configurable timeouts.
- Chat recovery hardening: turns now survive deploys and evictions without losing completed work. `useAgentChat` gains an `isRecovering` flag so your UI can show a recovery state, stalled streams recover via `chatStreamStallTimeoutMs`, and sub-agents re-attach to results instead of re-running when the parent recovers.
- MCP got better too: resumable SSE streams with `Last-Event-ID` reconnection, readable server IDs, and improved request correlation across HTTP and RPC.

Installing it is one line:

```
npm i agents@latest @cloudflare/think@latest @cloudflare/ai-chat@latest
```

For the finer details, the [Agents API reference](https://developers.cloudflare.com/agents/runtime/) has you covered.

## Wrap-up

- Agents SDK v0.14.0 adds Agent Skills, messengers, scheduled tasks, and Workflows integration
- Chat recovery is hardened for production, so turns survive deploys and evictions
- MCP transport improved around reconnection and IDs
- Install is a single `npm i agents@latest @cloudflare/think@latest @cloudflare/ai-chat@latest`

If you're building agents or chatbots on Cloudflare Workers, this update is right up your alley!
