hosted-agents
This skill should be used when designing hosted or background agent infrastructure: sandboxed execution, remote coding environments, warm pools, session persistence, multiplayer collaboration, self-spawning agents, or Modal-style sandboxes.
npx skills add guanyang/open-agent-hub --skill hosted-agents --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Hosted Agent Infrastructure Hosted agents run in remote sandboxed environments rather than on local machines. When designed well, they provide unlimited concurrency, consistent execution environments, and multiplayer collaboration. The critical insight is that session speed should be limited only by model provider time-to-first-token, with all infrastructure setup completed before the user starts their session. ## When to Activate Activate this skill when: - Building background coding agents that run independently of user devices - Designing sandboxed execution environments for agent workloads - Implementing multiplayer agent sessions with shared state - Creating multi-client agent interfaces (Slack, Web, Chrome extensions) - Scaling agent infrastructure beyond local machine constraints - Building systems where agents spawn sub-agents for parallel work Do not activate this skill for adjacent work owned by other skills: - Designing the autonomous research loop, novelty gates, rollback policy, or merge boundaries: `harness-engineering`. - Choosing supervisor, swarm, or handoff topology without hosted infrastructure concerns: `multi-agent-patterns`. - Designing the tools used by a h

What does the hosted-agents skill do?
This skill should be used when designing hosted or background agent infrastructure: sandboxed execution, remote coding environments, warm pools, session persistence, multiplayer collaboration, self-spawning agents, or Modal-style sandboxes.
How do I install it?
Run `npx skills add guanyang/open-agent-hub --skill hosted-agents --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From guanyang/open-agent-hub, a repository with 940 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
