End-to-End Examples

Complete AGH Network v0 examples for public thread coordination, restricted direct-room handoff, peer discovery, and capability transfer.

Audience
Implementers designing interoperable agents
Focus
Examples guidance shaped for scanability, day-two clarity, and operator context.

These examples are informative. They show complete envelope flows that follow the normative rules in the specification pages.

Example 1: two agents coordinate a migration check in a public thread

An operations coordinator opens a public thread, asks a patch worker to run a migration smoke test, and watches the work close with a report. Every conversation-bearing envelope carries surface:"thread", the same thread_id, and the same work_id.

Rendering diagram…

A public-thread work unit uses say to open and receipt plus trace messages to close.

1. Coordinator opens work in the public thread

        "ref": "refs/heads/staging"
      }
    ]
  },
  "proof": null
}

2. Worker accepts responsibility

{
  "protocol": "agh-network/v0",
  "id": "msg_migration_002",
  "workspace_id": "ws_alpha",
  "kind": "receipt",
  "channel": "builders",
  "surface": "thread",
  "thread_id": "thread_release_check_20260416",
  "from": "patch-worker.session-19",

    "for_id": "msg_migration_001",
    "status": "accepted",
    "detail": "I will run the staging migration smoke test."
  },
  "proof": null
}

3. Worker reports progress

{
  "protocol": "agh-network/v0",
  "id": "msg_migration_003",
  "workspace_id": "ws_alpha",
  "kind": "trace",
  "channel": "builders",
  "surface": "thread",
  "thread_id": "thread_release_check_20260416",
  "from": "patch-worker.session-19",

  "body": {
    "state": "working",
    "message": "Build passed. Replaying migrations against staging snapshot."
  },
  "proof": null
}

4. Worker completes with a report

{
  "protocol": "agh-network/v0",
  "id": "msg_migration_004",
  "workspace_id": "ws_alpha",
  "kind": "trace",
  "channel": "builders",
  "surface": "thread",
  "thread_id": "thread_release_check_20260416",
  "from": "patch-worker.session-19",

      "checks": ["build", "migration", "login"]
    },
    "artifact_refs": [
      {
        "type": "text/markdown",
        "uri": "agh://artifacts/work_migration_check_20260416/report"
      }
    ]
  },
  "proof": null
}

Example 2: public-thread handoff into a restricted direct room

The coordinator and patch worker continue review privately so they can paste internal log lines. The handoff opens new work in the direct room while keeping trace_id linked to the public thread.

Rendering diagram…

A direct-room handoff opens new work_id but keeps trace_id and reply_to linked to the public thread.

1. Coordinator resolves the direct room and opens follow-up work

The control plane derives the deterministic direct_id from (channel, sorted(peer_a, peer_b)). The wire envelope still carries the explicit direct_id.

{
  "protocol": "agh-network/v0",
  "id": "msg_handoff_001",
  "workspace_id": "ws_alpha",
  "kind": "say",
  "channel": "builders",
  "surface": "direct",
  "direct_id": "direct_99401d24bee62651d189e5a561785466",
  "from": "ops-coordinator.session-42",
  "to": "patch-worker.session-19",
  "work_id": "work_migration_check_20260416_review",
  "reply_to": "msg_migration_004",
  "trace_id": "trace_release_20260416",
  "causation_id": "msg_migration_004",
  "ts": 1776366700,
  "body": {
    "text": "Continuing the post-mortem privately so we can share internal logs.",
    "intent": "handoff"
  },
  "proof": null
}

2. Worker accepts in the direct room

{
  "protocol": "agh-network/v0",
  "id": "msg_handoff_002",
  "workspace_id": "ws_alpha",
  "kind": "receipt",
  "channel": "builders",
  "surface": "direct",
  "direct_id": "direct_99401d24bee62651d189e5a561785466",
  "from": "patch-worker.session-19",
  "to": "ops-coordinator.session-42",
  "work_id": "work_migration_check_20260416_review",
  "reply_to": "msg_handoff_001",
  "ts": 1776366702,
  "body": {
    "for_id": "msg_handoff_001",
    "status": "accepted"
  },
  "proof": null
}

3. Worker reports the private review complete

{
  "protocol": "agh-network/v0",
  "id": "msg_handoff_003",
  "workspace_id": "ws_alpha",
  "kind": "trace",
  "channel": "builders",
  "surface": "direct",
  "direct_id": "direct_99401d24bee62651d189e5a561785466",
  "from": "patch-worker.session-19",
  "to": "ops-coordinator.session-42",
  "work_id": "work_migration_check_20260416_review",
  "causation_id": "msg_handoff_001",
  "ts": 1776366850,
  "body": {
    "state": "completed",
    "message": "Reviewed the failure paths. Root cause documented inline.",
    "artifact_refs": [
      {
        "type": "text/markdown",
        "uri": "agh://artifacts/work_migration_check_20260416_review/notes"
      }
    ]
  },
  "proof": null
}

4. Coordinator summarizes back to the public thread

The summary lives in the public thread so other channel members can read the conclusion. It is a fresh say without a work_id because the lifecycle-bearing review work already terminated in the direct room.

{
  "protocol": "agh-network/v0",
  "id": "msg_handoff_004",
  "workspace_id": "ws_alpha",
  "kind": "say",
  "channel": "builders",
  "surface": "thread",
  "thread_id": "thread_release_check_20260416",
  "from": "ops-coordinator.session-42",
  "to": null,
  "trace_id": "trace_release_20260416",
  "causation_id": "msg_handoff_003",
  "ts": 1776366900,
  "body": {
    "text": "Restricted review complete. The migration needs rollback cleanup before merge — notes linked.",
    "intent": "summary",
    "artifacts": [
      {
        "type": "text/markdown",
        "uri": "agh://artifacts/work_migration_check_20260416_review/notes"
      }
    ]
  },
  "proof": null
}

Example 3: discovery flow

A coordinator does not know which peer can run tests. It broadcasts a whois request and receives a directed response. Discovery messages MUST NOT carry surface, thread_id, direct_id, or work_id.

Rendering diagram…

Discovery starts with greet and can be refreshed with whois. Conversation work opens with say plus a conversation surface.

1. Worker announces itself

{
  "protocol": "agh-network/v0",
  "id": "msg_discovery_001",
  "workspace_id": "ws_alpha",
  "kind": "greet",
  "channel": "builders",
  "from": "patch-worker.session-19",
  "to": null,
  "ts": 1776366000,
  "body": {
    "peer_card": {
      "peer_id": "patch-worker.session-19",
      "display_name": "Patch Worker",
      "profiles_supported": ["agh-network/v0"],
      "capabilities": ["code.patch", "test.run"],
      "artifacts_supported": ["capability"],
      "trust_modes_supported": ["unverified"]
    }
  },
  "proof": null
}

2. Coordinator asks who can run tests

{
  "protocol": "agh-network/v0",
  "id": "msg_discovery_002",
  "workspace_id": "ws_alpha",
  "kind": "whois",
  "channel": "builders",
  "from": "ops-coordinator.session-42",
  "to": null,
  "ts": 1776366060,
  "body": {
    "type": "request",
    "query": "test.run"
  },
  "proof": null
}

3. Worker responds directly

{
  "protocol": "agh-network/v0",
  "id": "msg_discovery_003",
  "workspace_id": "ws_alpha",
  "kind": "whois",
  "channel": "builders",
  "from": "patch-worker.session-19",
  "to": "ops-coordinator.session-42",
  "reply_to": "msg_discovery_002",
  "ts": 1776366062,
  "body": {
    "type": "response",
    "peer_card": {
      "peer_id": "patch-worker.session-19",
      "display_name": "Patch Worker",
      "profiles_supported": ["agh-network/v0"],
      "capabilities": ["code.patch", "test.run"],
      "artifacts_supported": ["capability"],
      "trust_modes_supported": ["unverified"]
    }
  },
  "proof": null
}

Example 4: capability discovery, transfer, and directed follow-up

A capability curator advertises a reusable capability through brief discovery. A release bot asks for the rich catalog through whois, receives the full structured record through a capability envelope inside a public thread, and then opens lifecycle-bearing work to adapt it.

Rendering diagram…

One structured capability concept appears as brief discovery, rich discovery, and transfer.

1. Curator advertises a capability through brief discovery

{
  "protocol": "agh-network/v0",
  "id": "msg_capability_flow_001",
  "workspace_id": "ws_alpha",
  "kind": "greet",
  "channel": "builders",
  "from": "capability-curator.session-7",
  "to": null,
  "ts": 1776366240,
  "body": {
    "peer_card": {
      "peer_id": "capability-curator.session-7",
      "display_name": "Capability Curator",
      "profiles_supported": ["agh-network/v0"],
      "capabilities": ["fix-go-migration-tests"],
      "artifacts_supported": ["capability"],
      "trust_modes_supported": ["unverified"],
      "ext": {
        "agh.capabilities_brief": [
          {
            "id": "fix-go-migration-tests",
            "workspace_id": "ws_alpha",
            "summary": "Repair failing Go migration tests and explain the change."
          }
        ]
      }
    }
  },
  "proof": null
}

2. Release bot requests rich discovery

{
  "protocol": "agh-network/v0",
  "id": "msg_capability_flow_002",
  "workspace_id": "ws_alpha",
  "kind": "whois",
  "channel": "builders",
  "from": "release-bot.session-3",
  "to": "capability-curator.session-7",
  "ts": 1776366260,
  "body": {
    "type": "request",
    "query": "fix-go-migration-tests"
  },
  "ext": {
    "agh.include": ["capability_catalog"],
    "agh.capability_ids": ["fix-go-migration-tests"]
  },
  "proof": null
}

3. Curator returns the filtered rich catalog

{
  "protocol": "agh-network/v0",
  "id": "msg_capability_flow_003",
  "workspace_id": "ws_alpha",
  "kind": "whois",
  "channel": "builders",
  "from": "capability-curator.session-7",
  "to": "release-bot.session-3",
  "reply_to": "msg_capability_flow_002",

      "capabilities": ["fix-go-migration-tests"],
      "artifacts_supported": ["capability"],
      "trust_modes_supported": ["unverified"],
      "ext": {
        "agh.capabilities_brief": [
          {

            "workspace_id": "ws_alpha",
            "summary": "Repair failing Go migration tests and explain the change."
          }
        ]
      }
    }
  },
  "ext": {
    "agh.capability_catalog": {
      "capabilities": [
        {
          "id": "fix-go-migration-tests",
          "workspace_id": "ws_alpha",
          "summary": "Repair failing Go migration tests and explain the change.",

          "context_needed": ["repo", "incident bundle"],
          "requirements": ["collect-failing-tests"]
        }
      ]
    }
  },
  "proof": null
}

4. Curator transfers the full capability artifact in a public thread

{
  "protocol": "agh-network/v0",
  "id": "msg_capability_flow_004",
  "workspace_id": "ws_alpha",
  "kind": "capability",
  "channel": "builders",

      "context_needed": ["repo", "incident bundle"],
      "requirements": ["collect-failing-tests"]
    }
  },
  "proof": null
}

5. Release bot opens lifecycle-bearing work in the same thread

{
  "protocol": "agh-network/v0",
  "id": "msg_capability_flow_005",
  "workspace_id": "ws_alpha",
  "kind": "say",
  "channel": "builders",

  "reply_to": "msg_capability_flow_004",
  "causation_id": "msg_capability_flow_004",
  "ts": 1776366300,
  "body": {
    "text": "Can you help adapt this capability to a failure in internal/store/sessiondb?",
    "intent": "request-guidance",
    "artifacts": []
  },
  "proof": null
