View in browser https://newsletter.composio.dev/issues/03 October 2026 ---------------------------------------- In the last issue https://newsletter.composio.dev/issues/02, we gave you an early look at Instant. Now Composio Instant https://composio.dev/instant is live for everyone. COMPOSIO INSTANT: YOUR AGENT CAN DO MORE, WITHOUT MORE SUBSCRIPTIONS https://composio.dev/instant We just launched Composio Instant https://composio.dev/instant, giving your agent access to paid services without requiring separate accounts or subscriptions. Research companies, find contacts, scrape websites, transcribe audio, generate images, and more. Here's an example: You ask your agent to find the right contacts at 30 companies. Instead of signing up for multiple services, it can search with Exa, scrape with Firecrawl, and find emails with Hunter or Findymail. You give it the task; it figures out which services to use. https://composio.dev/instant Works with your connected apps: Composio already connects your agent to Gmail, Google Sheets, Slack, and more. Instant adds new capabilities when needed, prioritizing your existing connected accounts. One wallet, no extra subscriptions: Pay per call from a single Composio wallet, with transparent pricing, no markups, and no charges for failed calls. Try it with $2 in free credit. Every new account gets a starting balance to put Instant to work on a real task. Instant works with Claude, ChatGPT, Cursor, and other supported agents. Developers can also enable Instant for their own users https://docs.composio.dev/docs/instant-tools.

The challenge: build an open-source personal agent that does something useful in a real app. Turn meeting notes into Linear tasks. Turn a bug report into a researched GitHub issue. Or turn a question into a cited document. Bring a problem you're tired of solving by hand. When: Monday, October 19, 2026, 11:00 AM–4:30 PM Pacific Where: Frontier Tower, 995 Market Street, San Francisco Cost: Free to attend. You'll get $50 in Cline credits, and there are prizes for the top three projects. Come solo or with a team. Just bring a laptop and something you want an agent to take off your plate. Register for the hackathon https://luma.com/m8euvq9n AGENTS @ WORK UPDATE: SEE WHAT AI AGENTS ARE ACTUALLY DOING https://composio.dev/agents-at-work We just refreshed Agents @ Work https://composio.dev/agents-at-work with new data through October 14. Which apps do AI agents use most? What kinds of work are growing fastest? Which apps do they use together to finish a job? Agents @ Work helps answer those questions using a sample of real actions running through Composio. A few interesting findings from the latest update: * Marketing was the fastest-growing category, with agent activity up more than 70% compared with the previous week. * Communication apps accounted for more than 40% of agent actions in the sample. Email and messaging remain a huge part of what agents do. * Re:amaze, HighLevel, and Deepgram were among the fastest-growing apps used by agents. You can also explore which apps agents combine, what kinds of tasks they take on, and how often similar work comes up. If you're looking for ideas for what to automate next, it's a good place to start. Explore Agents @ Work https://composio.dev/agents-at-work 40+ NEW APPS ADDED, INCLUDING COINBASE Since the last issue, we've added more than 40 new apps to Composio, bringing the catalog past 1,600 toolkits. Coinbase https://x.com/CoinbaseDev/status/2110420906166407437: Connect your Coinbase account and your agent can check prices, preview and place trades, and manage your portfolio on Coinbase Advanced Trade, all from a chat. A few more highlights from this batch: * Business tools: ServiceTitan, Aircall, SignNow, HighLevel Agency, and WorkOS * AI and media: Black Forest Labs, Higgsfield, Cohere, CrewAI, Browser Use, and Wispr Flow * Developer tools: Temporal, PlanetScale, Harness, Statsig, and Unleash * Marketing: AdRoll, SendPulse, vidIQ, and Disqus Browse the toolkits https://dashboard.composio.dev/ FOR DEVELOPERS APPROVALS: LET YOUR USERS SIGN OFF BEFORE THE AGENT ACTS Your agent can gather information on its own. But before it sends an important email or deletes something, you might want your users to have the final say. Sessions now support approvals for tool execution. Choose which tools need sign-off. Before the agent runs one of them, your user gets a prompt to approve, always approve, or deny the call, and routine work stays automatic. It also works over session MCP, so clients like Claude Code prompt the user directly. Approvals are experimental for now. Set up approvals https://docs.composio.dev/docs/approvals MORE RELIABLE TOOL USE IN PYTHON Two community-requested improvements have been merged: Anthropic prompt caching for the Python provider and strict-mode support for OpenAI Agents. Release preparations are also merged for Python 0.26.0 and TypeScript 0.23.0, including a fix for a Python 3.10 import issue. Check the published release tags before upgrading.
