Built-in agents

The agents Curia ships with — what each does, when it’s invoked, and how the coordinator dispatches to specialists.

Curia ships with a small team of specialized agents. The Coordinator is the central router — every inbound message goes to it first. It handles most tasks directly and delegates to specialist agents when their expertise is needed.

Coordinator

The Coordinator is Curia’s primary agent. It receives every inbound message, maintains the unified persona, and decides whether to handle a task itself or delegate to a specialist.

Field	Value
Role	coordinator
Model	Claude Sonnet
Skills	50+ pinned skills (contacts, email, calendar, memory, scheduling, web research, autonomy, and more)
Discovery	Enabled — can find and invoke skills not in its pinned list

What it handles directly:

• Conversational messages and questions
• Contact management (create, lookup, merge, permissions)
• Email reading, sending, replying, and drafting
• Calendar operations (list, create, update, delete events, find free time)
• Scheduling recurring and one-shot tasks
• Knowledge graph queries and memory storage
• Autonomy score management
• Web research (search, fetch, browse)
• Held message processing for unknown senders

Key behaviors:

• Adapts its communication style based on who it’s talking to — candid with the CEO, professional and opaque with external contacts
• Never exposes internal system details, tool names, or agent architecture to non-CEO users
• Enforces authorization decisions from the dispatch layer (provisional contacts, blocked senders, permission denials)
• Respects trust score thresholds before taking action on external requests
• Delegates observation-mode email triage to the Email Triage specialist

Email Triage

A specialist agent that triages the CEO’s inbound email when running in observation mode. The Coordinator delegates observation-mode emails to it automatically.

Field	Value
Role	specialist
Model	Claude Sonnet
Skills	email-list, email-get, email-archive, email-draft-save, entity-context, bullpen
Discovery	Disabled

Classification categories (evaluated in priority order):

Category	Action taken
URGENT	Opens a Bullpen thread to alert the Coordinator. Does not reply to the sender.
ACTIONABLE	Opens a Bullpen thread mentioning the capable specialist with a handoff summary.
NEEDS DRAFT	Saves a draft reply in the CEO’s inbox for review before sending.
LEAVE FOR CEO	Takes no action — the email is left for the CEO to handle.
NOISE	Archives the message (receipts, newsletters, automated notifications).

Before classifying, the Email Triage agent checks for standing instructions on the sender (via entity-context) — per-sender rules override the default triage protocol.

Research Analyst

A specialist agent for conducting web research and providing analysis.

Field	Value
Role	specialist
Model	Claude Sonnet
Skills	web-search, web-fetch, scheduler-create, scheduler-list, scheduler-cancel
Discovery	Disabled

Research workflow:

1. Uses web-search (Tavily) with multiple queries to cover different angles
2. Follows up on important sources with web-fetch for full content
3. Synthesizes findings into clear, concise summaries for an executive audience
4. Highlights key takeaways and concerns with source attribution

The Coordinator delegates to the Research Analyst when a request requires multi-source web research rather than a simple lookup.

How delegation works

When the Coordinator receives a task that requires specialist expertise, it uses the delegate skill to hand the task to the appropriate agent. The specialist works independently, using only its pinned skills, and returns its findings to the Coordinator. The Coordinator then synthesizes the specialist’s response into its own voice — the user never sees that multiple agents were involved.

On synchronous channels (CLI, Signal, HTTP), the Coordinator sends a brief acknowledgment before delegating (“This will take a few minutes — I’ll reply when it’s ready”). On asynchronous channels (email), delegation happens silently.
