## What hephaestus does, in the publisher's words

macOS (Apple silicon and Intel) &middot; Windows &middot; Linux &mdash; agentlas.cloud/desktop

Agentlas OS

Build it or borrow it. The agents you create stay yours. Turn a plain-language request into a runnable agent or team, borrow specialists from the public Agentlas Hub, and keep the agents you create available through your private, owner-scoped Agent Cloud. Run them through supported hosts for the LLMs you already use. Hephaestus is the open-source engine underneath.

- Do you already have Git Bash? Click the search icon (or press the Windows key) in your taskbar and type git bash.
- If "Git Bash" shows up in the results, click it and skip to step 3.

## Skills

- agent-team-design: Use when designing a new multi-agent team, visible agents folder, role boundaries, handoff flow, PM Soul, Memory Curator, Policy Gate, or evaluation role. Use for agent-team repo creation even when the user only says they want a meta-agent or agent operating system.
- agentlas-auto-activation: Use when adding or auditing local runtime behavior that turns a project folder into an Agentlas-aware workspace with.agentlas memory and sitemap files.
- agentlas-browser: Use when the user types /agentlas-browser <url-or-query>, /agentlas browser, or /hep-browser for browser-required tasks, rendering pages, form flows, or visual evidence.
- agentlas-build: Use when the user types /agentlas-build, /agentlas build, or /hep-build to design, build, and package a single agent or multi-agent team.
- agentlas-call: Use when the user types /agentlas-call <agents> <context>, /agentlas call, or /hep-call to borrow and execute named Agentlas Hub/Cloud agents attached to the current project.
- agentlas-cloud: Use when the user types /agentlas-cloud, /agentlas cloud, or /hep-cloud to staff only from the signed-in owner's private Cloud packages.
- agentlas-connect: Use when the user types /agentlas-connect <channel>, /agentlas connect, or /hep-connect to connect Agentlas channels (Slack, Discord, Telegram, etc.).
- agentlas-graph: Use when the user types /agentlas-graph, /agentlas graph, or /hep-graph to create, list, inspect, or run Agentlas automation graphs.

- agentlas-local: Use when the user types /agentlas-local, /agentlas local, or /hep-local to staff only from registered Local packages.
- agentlas-network: Use when the user types /agentlas-network, /agentlas network, $hephaestus-network, or /hep-network to staff a durable goal from registered Local, owner Cloud, and public Hub agents or teams.
