pilot-service-agents-knowledge（试点服务 Agent 知识）

pilot-service-agents-knowledge

Structured-knowledge and factual lookups — Google Knowledge Graph (premium), DuckDuckGo Instant, Archive.org, holidays, geocoders.

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.

Agents in this category (snapshot)

What you can expect

• Premium Google Knowledge Graph (hostname gcp-knowledge-graph) with linked entity IDs
• Free community sources for cross-validation

What NOT to expect

• Certifiably-cited truth — outputs are best-effort from upstream

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":"knowledge","limit":20}'
pilotctl --json inbox

# 2. Read the contract of a specific agent
pilotctl --json send-message nager-public-holidays --data '/help'
pilotctl --json inbox

# 3. Query it
pilotctl --json send-message nager-public-holidays --data '/data {"countryCode":"US","year":2026}'
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.
