agento11y-claude-agent-sdk 0.10.0

Claude Agent SDK hooks for the Grafana Agent Observability Python SDK

Sigil Python Framework Module: Claude Agent SDK

agento11y-claude-agent-sdk records Claude Agent SDK sessions as Sigil generations and maps Claude tool hooks to Sigil tool spans.

Installation

pip install agento11y agento11y-claude-agent-sdk
pip install claude-agent-sdk

The Claude Agent SDK runs the Claude Code CLI. Authenticate and configure Claude Code the same way you would for a normal Claude Agent SDK application.

Quickstart

import asyncio

from claude_agent_sdk import ClaudeAgentOptions
from agento11y import Client
from agento11y_claude_agent import agento11y_query


async def main():
    client = Client()
    try:
        async for message in agento11y_query(
            prompt="List the files in this directory.",
            options=ClaudeAgentOptions(
                permission_mode="default",
                model="claude-sonnet-4-5",
            ),
            client=client,
            conversation_id="demo-claude-agent-sdk",
            agent_name="claude-agent-demo",
        ):
            print(message)
    finally:
        client.shutdown()


asyncio.run(main())

Existing ClaudeSDKClient Usage

For bidirectional sessions, attach hooks to your ClaudeAgentOptions and pass every stream message to the handler:

from claude_agent_sdk import ClaudeAgentOptions
from agento11y import Client
from agento11y_claude_agent import Agento11yClaudeSDKClient

agento11y = Client()
options = ClaudeAgentOptions(permission_mode="default")

async with Agento11yClaudeSDKClient(
    client=agento11y,
    options=options,
    conversation_id="customer-42",
    agent_name="support-agent",
) as claude:
    await claude.query("Help me inspect this project.")
    async for message in claude.receive_response():
        print(message)

    await claude.set_permission_mode("acceptEdits")

agento11y.shutdown()

Agento11yClaudeSDKClient forwards query(), receive_response(), receive_messages(), set_permission_mode(), rewind_files(), interrupt(), and disconnect() to the wrapped Claude client. Use agento11y_query() for simple single-query scripts and Agento11yClaudeSDKClient when you need Claude SDK session control such as permission mode changes, resume/checkpoint flows, or multiple queries in one client session.

Guards

Sigil guards run through Claude Agent SDK hooks:

• UserPromptSubmit evaluates the submitted prompt before Claude proceeds. A Sigil deny returns continue_=False, stopping the run.
• PreToolUse evaluates tool requests before execution. A Sigil deny maps to Claude's permissionDecision="deny".

Enable guards on the Sigil client:

from agento11y import Client, ClientConfig, HooksConfig

client = Client(ClientConfig(hooks=HooksConfig(enabled=True)))

HooksConfig keeps the core SDK defaults: preflight phase, 15 second timeout, and fail-open transport behavior unless configured otherwise.

Conversation Mapping

Conversation ID precedence:

1. Explicit conversation_id passed to the Sigil handler or agento11y_query
2. ClaudeAgentOptions.session_id
3. ClaudeAgentOptions.resume
4. unique fallback agento11y:framework:claude-agent-sdk:<run_id>

Agento11yClaudeSDKClient uses the same explicit conversation_id, session_id, and resume precedence. If none are set, it creates one client-level fallback conversation ID and reuses it for every query in that client session so multi-query sessions stay grouped.

When Claude returns a session ID in the stream, the handler also records it in generation metadata as agento11y.framework.session_id.

Metadata

Required framework tags:

• agento11y.framework.name=claude-agent-sdk
• agento11y.framework.source=hooks
• agento11y.framework.language=python

Metadata includes:

• agento11y.framework.run_id
• agento11y.framework.run_type=agent
• agento11y.framework.session_id when Claude returns one
• agento11y.claude_agent.permission_mode when configured
• agento11y.claude_agent.cwd when configured
• agento11y.claude_agent.total_cost_usd when Claude returns cost data

Claude Native OpenTelemetry

This package records Sigil generations and tool spans through the Sigil Python SDK. The Claude Agent SDK can also make the Claude Code CLI export its native OpenTelemetry spans, metrics, and logs directly to your OTLP collector. Configure those variables in the parent process before calling agento11y_query; the Python Claude Agent SDK merges options.env on top of the inherited environment.

For Grafana Cloud, the important Claude variables are:

CLAUDE_CODE_ENABLE_TELEMETRY=1
CLAUDE_CODE_ENHANCED_TELEMETRY_BETA=1
OTEL_TRACES_EXPORTER=otlp
OTEL_METRICS_EXPORTER=otlp
OTEL_LOGS_EXPORTER=otlp
OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
OTEL_EXPORTER_OTLP_ENDPOINT=https://otlp-gateway-prod-<region>.grafana.net/otlp
OTEL_EXPORTER_OTLP_HEADERS=Authorization=Basic <base64 of OTLP_INSTANCE_ID:SIGIL_AUTH_TOKEN>

Do not use the console OTel exporter with the Claude Agent SDK; stdout is part of its message channel.

Local Validation

From the repository root:

mise run test:py:sdk-claude-agent-sdk

To run only this package manually:

uv run --python "$PYTHON_BIN" \
  --with './python[dev]' \
  --with-editable './python-frameworks/claude-agent-sdk[dev]' \
  pytest python-frameworks/claude-agent-sdk/tests

Troubleshooting

• If generations are fragmented, pass a stable conversation_id.
• If no Claude native traces appear, verify CLAUDE_CODE_ENABLE_TELEMETRY=1, an OTLP exporter is selected, and the endpoint/header values are visible to the Python process.
• If guards do not run, make sure the Sigil client was created with ClientConfig(hooks=HooksConfig(enabled=True)).
• Always call client.shutdown() during teardown.
