chat.nvim Adds Scheduled Tasks to Give AI Assistants a Sense of Time

A new scheduled task feature has been added to chat.nvim, a Neovim plugin, to address a core limitation of most AI assistants — their inability to act proactively at a future point in time. The feature allows users to schedule reminders or tasks using relative delays, absolute timestamps, or recurring intervals, all of which are internally converted to Unix timestamps for a unified scheduling model. Rather than polling, the system uses Neovim's built-in libuv library to create one independent timer per task, waking only when due to avoid unnecessary CPU usage. A drift-correction algorithm ensures recurring tasks maintain their original rhythm even after Neovim restarts, and a timer-sharding workaround handles durations beyond libuv's 24.8-day hard limit. When a scheduled task triggers, it injects a message into the active session so the AI processes it as if the user had just sent it.
