Show HN: Fast-agent – Compose MCP enabled Agents and Workflows in minutes Hello, HN. I've created fast-agent to make building my own products easier - and remove the friction between defining Prompts, MCP Servers and their composition. It uses a simple, declarative style that's easy to work with and source control - with inbuilt support for the patterns in the Building Effective Agents paper. Because you can "warm-up" and interact with Agents before, during or after the workflows, it's easy to diagnose and tune Agent prompts and behaviour for later runs. Being able to set these workflows up makes LLM Context Management and Tool Selection a lot easier and can vastly improve output quality for little effort. For MCP Server developers you can see how different models interpret tool descriptions. There's also MCP Roots support, and it comes bundled with a ChatGPT style data-analysis tool (`fast-agent bootstrap data-analysis`) as one of the demonstrations. One of the thing I am most looking forward to is combining MCP data retrieval with Anthropic's Citations API - I think that's going to be an incredibly important feature in a lot of scenarios. It's been forked from, and and builds upon Sarmad Qadri's mcp-agent framework, and we're collaborating to keep the projects in-sync. Anyway, I'd love to hear your thoughts and feedback on this project, and eager to hear from potential users, contributors and collaborators. https://ift.tt/IBx8nSE March 6, 2025 at 11:34PM

Twin Peaks for All: Survey Results By Benjamin Barnett Last month, the SFMTA and San Francisco Recreation and Parks Department released a survey seeking public feedback regarding  five proposed roadway options for Twin Peaks Boulevard .

Welcoming Back the M Ocean View and 31 Balboa

Welcoming Back the M Ocean View and 31 Balboa By Kate McCarthy The M Ocean View will return to rail service and resume its full pre-pandemic route in August As August 14 approaches, the target date for the next big Muni service change, the SFMTA is pleased to announce Muni’s M Ocean View will be returning to rail service and the 31 Balboa will be returning to service with a temporarily adjusted route. We thank Supervisors Melgar, Safai, Preston and Haney for their advocacy for the return of this service on behalf of their constituents. The addition of the 31 Balboa and return of the M Ocean View to rail service was made possible following improved clarity on our staffing levels this fall. We had previously forecast that due to an abnormally low level of retirements during the pandemic, we would see a spike at the start of the fiscal year (July 1) when many staff tend to announce their retirements. However, we are now confident there will be adequate staffing to deliver this addit...
