Asynchronous Long Running Agent Workflows

via “background task execution and async job management”

Bash is all you need - A nano claude code–like 「agent harness」, built from 0 to 1

Unique: Exposes background task management as a tool the agent can call, rather than hiding it in the harness. This makes async patterns visible to the agent and allows it to reason about job status and dependencies.

vs others: More transparent than frameworks that automatically parallelize tool execution, because the agent explicitly decides which tasks to background and can monitor their progress. Trades off automatic optimization for explicit control.
