What it does
Setting up AI agents shouldn't be a series of one-off clicks. Kasetto turns your AI Skills and MCP servers into a single YAML file the same way you'd manage dependencies in any other project. Version it in Git, share it with your team, run "kst sync", and every machine ends up identical. Use global or project scope, layer personal configs on top of a shared team base with "extends" ke, and onboard a new teammate in one command. Reproducible by default, written in Rust
Sync skills, MCP servers, slash-commands, and instructions from Git into Claude Code, Cursor, Codex, Copilot, and 18 more agents. One YAML file, lock-pinned, in Rust.
One YAML file: skills, commands, MCPs, and instructions. Apply globally or per project; compose with `extends`. Pull from GitHub, GitLab, Bitbucket, or self-hosted repos, public or private. Secrets resolve from `kst_*` placeholders at sync time, so they're never committed or locked. Write once, ship everywhere. Claude Code, Cursor, Codex, Copilot: one sync keeps every agent current. All four asset kinds from one source, transformed into each agent's native format and auto-merged. Share tools and prompts like a repo link. Built in Rust. Content is hashed and diffed against a lock file, so only what changed is touched. Syncs finish in seconds. One static binary for macOS, Linux, and Windows.…from kasetto.dev

Run AI Agents on your cloud infrastructure2025 · okteto.com · ▲12Hi, founder of Okteto here! We’ve been experimenting with AI agents in our workflows at Okteto. Running them locally worked at first, but quickly became painful. git worktrees, multiple terminals, and messy context switches slowed us down. So we built Agent Fleets: ephemeral, fully managed environments for AI agents, built on top of Okteto’s development platform. Each agent runs in its own containerized environment on your infrastructure, with the services, tools, and policies it needs. You can spin up agents with a single click or API call. No local setup. No git worktrees. The beta…

Parallel agents, diff reviewer, and multi-model comparisons

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
