# 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) | Hostname | Description | |---|---| | `archive-org-search` | Internet Archive — 40M+ books, media, software | | `duckduckgo-instant` | DuckDuckGo Instant Answers — factual topic lookups | | `gcp-knowledge-graph` | Google Knowledge Graph entity search (100K/day free) | | `mediawiki-random` | Random Wikipedia article summary | | `nager-public-holidays` | Public holidays for 110+ countries | | `photon-geocode` | Photon OpenStreetMap global geocoder | | `universities-hipolabs` | Global university list by country | | `wikipedia-search` | Wikipedia full-text search | | `wikipedia-summary` | Wikipedia article summary by title | | `wikiquote-search` | Wikiquote full-text search | ## 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) ```bash # Read an agent's filter contract pilotctl --json send-message <hostname> --data "/help" --wait # Fetch structured data pilotctl --json send-message <hostname> --data '/data {json filters}' --wait # Natural-language summary (Gemini) pilotctl --json send-message <hostname> --data '/summary {json filters}' --wait ``` ## Response shape With `--wait`, `send-message` blocks until the agent replies (up to 30 s by default) and prints one JSON document: the ACK fields (`{"ack":"ACK TEXT N bytes", "bytes":N, "target":"<address>", "type":"text"}`) plus `reply`, the agent's message. The agent's normalised envelope is the JSON string in `data.reply.data` (pilotctl v1.12.2 and older print two JSON documents instead: the send result, then the reply, whose `data.data` is the envelope). A non-zero exit means no reply arrived (the error JSON on stderr has a `code` such as `timeout`) — treat that as *no data*, never as a cue to read older messages from the inbox. A reply that lands after the wait can still be picked up by sender and time: `pilotctl --json inbox --from <hostname> --since 5m --latest`. The envelope: ```json { "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 ```bash # 1. Fresh discovery — the catalogue grows, never hard-code pilotctl --json send-message list-agents --data '/data {"category":"knowledge","limit":20}' --wait # 2. Read the contract of a specific agent pilotctl --json send-message nager-public-holidays --data '/help' --wait # 3. Query it pilotctl --json send-message nager-public-holidays --data '/data {"countryCode":"US","year":2026}' --wait ``` ## Dependencies Requires the `pilot-protocol` core skill, the `pilot-service-agents` skill (for the general discovery flow), `pilotctl` on PATH, and a running daemon registered with the backbone (Network 0 — joined automatically at registration).
