Lightweight utility lookups — dictionaries, jokes, colors, currencies, random facts, D&D data, etc.

All agents in this category follow the standard contract described in pilot-service-agents. Send /help to any agent to read its exact filter schema — the table below is a snapshot; the catalogue grows, so always verify with a fresh list-agents query.

What you can expect

• Many small, single-purpose wrappers — fast responses, no auth, no quota concerns
• English dictionary, Datamuse word tools, jokes/trivia/advice APIs
• ECB currency and historical FX (no authentication needed)

What NOT to expect

• Deep analytical data — this is the grab-bag of small useful APIs
• Always-current pricing — market data lives in finance

Commands (same pattern for every agent in the category)

# Read an agent's filter contract
pilotctl --json send-message <hostname> --data "/help"
pilotctl --json inbox

# Fetch structured data
pilotctl --json send-message <hostname> --data '/data {json filters}'
pilotctl --json inbox

# Natural-language summary (Gemini)
pilotctl --json send-message <hostname> --data '/summary {json filters}'
pilotctl --json inbox

Response shape

send-message returns an ACK envelope immediately ({"ack":"ACK TEXT N bytes", "bytes":N, "target":"<address>", "type":"text"}). The actual agent response arrives a few seconds later and is read with pilotctl --json inbox. Each inbox entry carries the agent's normalised envelope in its data field:

{
  "source": "<hostname>",
  "items":  [...],
  "count":  <int>,
  "total":  <int|null>,
  "page":   <int|null>,
  "next":   <cursor|null>,
  "truncated": <bool>,
  "upstream_url": "<resolved upstream URL>"
}

/help returns plain text. /summary returns a Gemini-generated prose string. Free-text queries also return Gemini prose.

Workflow Example

# 1. Fresh discovery — the catalogue grows, never hard-code
pilotctl --json send-message list-agents --data '/data {"category":"reference","limit":20}'
pilotctl --json inbox

# 2. Read the contract of a specific agent
pilotctl --json send-message free-dictionary-en --data '/help'
pilotctl --json inbox

# 3. Query it
pilotctl --json send-message free-dictionary-en --data '/data {"word":"serendipity"}'
pilotctl --json inbox

Dependencies

Requires the pilot-protocol core skill, the pilot-service-agents skill (for the general discovery flow), pilotctl on PATH, and a running daemon joined to network 9.
