+### Inline Agent Card JSON
+
+<details>
+<summary>View formatting options for JSON strings</summary>
+
+If you don't have an endpoint serving the agent card, you can provide the A2A
+card directly as a JSON string using `agent_card_json`.
+
+When providing a JSON string in YAML, you must properly format it as a string
+scalar. You can use single quotes, a block scalar, or double quotes (which
+require escaping internal double quotes).
+
+#### Using single quotes
+
+Single quotes allow you to embed unescaped double quotes inside the JSON string.
+This format is useful for shorter, single-line JSON strings.
+
+```markdown
+---
+kind: remote
+name: single-quotes-agent
+agent_card_json:
+  '{ "protocolVersion": "0.3.0", "name": "Example Agent", "version": "1.0.0",
+  "url": "dummy-url" }'
+---
+```
+
+#### Using a block scalar
+
+The literal block scalar (`|`) preserves line breaks and is highly recommended
+for multiline JSON strings as it avoids quote escaping entirely. The following
+is a complete, valid Agent Card configuration using dummy values.
+
+```markdown
+---
+kind: remote
+name: block-scalar-agent
+agent_card_json: |
+  {
+    "protocolVersion": "0.3.0",
+    "name": "Example Agent Name",
+    "description": "An example agent description for documentation purposes.",
+    "version": "1.0.0",
+    "url": "dummy-url",
+    "preferredTransport": "HTTP+JSON",
+    "capabilities": {
+      "streaming": true,
+      "extendedAgentCard": false
+    },
+    "defaultInputModes": [
+      "text/plain"
+    ],
+    "defaultOutputModes": [
+      "application/json"
+    ],
+    "skills": [
+      {
+        "id": "ExampleSkill",
+        "name": "Example Skill Assistant",
+        "description": "A description of what this example skill does.",
+        "tags": [
+          "example-tag"
+        ],
+        "examples": [
+          "Show me an example."
+        ]
+      }
+    ]
+  }
+---
+```
+
+#### Using double quotes
+
+Double quotes are also supported, but any internal double quotes in your JSON
+must be escaped with a backslash.
+
+```markdown
+---
+kind: remote
+name: double-quotes-agent
+agent_card_json:
+  '{ "protocolVersion": "0.3.0", "name": "Example Agent", "version": "1.0.0",
+  "url": "dummy-url" }'
+---
+```
