Included Skills4

activityskills/activity/SKILL.md

Track and report time spent on named activities in Nestor. Use when the user starts, switches, or stops an activity timer; asks for daily, weekly, or monthly activity totals; or wants to rename, merge, adjust, or delete activity data. Do not use for task status changes or general questions about physical activities.

check-for-updatesskills/check-for-updates/SKILL.md

Check whether the Nestor plugin is up to date. Use when the user asks if Nestor is current, wants the latest changelog, or types /nestor:check-for-updates or /check-for-updates.

nestorskills/nestor/SKILL.md

Use the Nestor MCP server as the canonical source whenever the user asks to consult or change tasks, todos, action items, backlog, journal entries, notes, memos, reminders, history, journal projects, tags, priorities, due dates, pending work, or next actions. Trigger even when the user does not mention Nestor or MCP, including equivalent requests in any language such as asking what to do next, recording something, adding or completing a task, logging progress, checking project status, or finding a past note. Use the activity skill instead for starting, switching, stopping, repairing, or reporting activity time. Do not trigger for generic software logs or unrelated project work unless the user asks to store or retrieve that information in the journal.

treeskills/tree/SKILL.md

Render an ASCII tree of a Nestor project's tasks and notes, grouped by status then by parent-child hierarchy. Use it whenever someone wants to see the shape of a project rather than a flat list — asking for an overview, a map, a tree, a structure, the hierarchy of tasks, what hangs under a given task, or how a project is organised. Also use it when the request names a project and asks "where are we" or "what hangs under this task", in any language. Prefer this skill over a plain list whenever parent-child relationships or per-status grouping carry the answer.
