A proactive chief-of-staff plugin for Vellum personal assistants. It frees up a user's routine administrative load by running in the background and surfacing only what matters:
- Morning digest — calendar + meeting prep, inbox triage summary, competitor deltas, and stale follow-ups, in one scannable brief.
- Inbox triage (propose-then-confirm) — ongoing email management that pre-sorts
noise and proposes actions; it never auto-sends and archives only what the user
approves. Delegates to the first-party
inbox-managementtrust ladder. - Calendar prep — meeting prep, gaps, and conflicts, surfaced in the digest.
- Weekly competitor brief — tracks a saved competitor list and reports only what materially changed (pricing, launches, funding, hiring, positioning).
It is an orchestration layer: it composes the assistant's existing email, calendar, digest, scheduling, and notification capabilities rather than re-implementing them, and adds the one missing pillar — recurring competitor research with week-over-week diffing.
Install
From the Vellum plugin marketplace:
assistant plugins install admin-copilot
Then ask your assistant to "set up my admin copilot" to walk onboarding and turn on the proactive schedules.
Surfaces
| Surface | Path | What it does |
|---|---|---|
| Skill | skills/admin-copilot-setup/ | One-time guided onboarding: capture preferences, connect accounts, and register the proactive schedules. |
| Skill | skills/admin-digest/ | The unified morning briefing (calendar, inbox triage summary, competitor deltas, follow-ups). |
| Skill | skills/competitor-brief/ | Recurring competitor monitoring with a content-hash pre-filter + model-judged materiality + week-over-week diff. |
| Skill | skills/admin-copilot-prefs/ | The shared state layer: ships the admin_copilot_prefs tool (via TOOLS.json), included by the three skills above. |
The plugin is skills-only — no hooks and no always-on tools. The
admin_copilot_prefs tool is declared in the admin-copilot-prefs skill's
TOOLS.json, so it registers only while an admin-copilot skill is active in a
conversation (invoked through skill_execute, executed in the skill sandbox)
and adds zero prompt cost to ordinary chat. Proactivity is delivered entirely
by schedules created at setup time, model-mediated — never at daemon
startup.
Configuration
All preferences live in prefs.json in the plugin's data directory, seeded on
first use of the admin_copilot_prefs tool and edited only through it / the
setup skill. See skills/admin-copilot-prefs/tools/prefs.ts for the shape and
defaults. No credentials are owned by the plugin — Gmail/Calendar auth stays
with the assistant's existing connectors. Installing the plugin is itself the
enablement gate; there is no separate feature flag.
Local development
# Copy into the workspace the assistant scans. A running assistant picks the
# plugin up automatically on its next turn — no restart needed.
cp -R admin-copilot "$(assistant daemon workspace)/plugins/admin-copilot"
assistant plugins list # → admin-copilot, status: ok
