Individual skill

check-the-shelf

Use when a task needs something that must keep running or stay reachable after this session ends, and the project has nothing that does it yet: a public URL that receives webhooks or callbacks, memory or files shared between sessions or machines, a wake-up or schedule for later, watching a site or a job and alerting someone, a backend for a form on a static site, a queue other agents pick up from, or asking the human by email while they are away. Also when the user wants an email list checked for bounces or a domain's email DNS checked. Compares a hosted AgentMart part with building it and with free options, then lets the user choose. Not for the user's own product code, and not when they asked you to build it yourself.

# Check the shelf before building an always-on part

AgentMart hosts small always-on parts (a webhook inbox, a memory locker, wake-up calls, uptime and
heartbeat watch, a task queue, a form inbox, share links, ask-my-human) for 30 days or more, runs
two email checks, and sells tested TypeScript code kits. This skill helps you compare honestly. It
never decides for the user, and it never buys on its own.

## When to use it

Use it when the task needs a part that one session cannot provide, and the user's own stack has
nothing for it yet:

- a public address that receives webhooks or callbacks while nobody is at the keyboard
- memory or files that must survive between sessions, or be shared between machines or agents
