introspection-sdk 0.6.1

Python SDK for Introspection — continuously improve your AI systems with production feedback and frontier practices

Build frontier AI systems that self-improve.

Introspection continuously improves your AI systems with production feedback and frontier practices. This is the Python SDK.

Install

uv add introspection-sdk
# or
pip install introspection-sdk

The default install is everything you need for the Introspection API (runtimes, tasks, files, conversations) — no OpenTelemetry pulled in. To also emit analytics events and export traces, add the [otel] extra; see OpenTelemetry below.

Introspection API (runtimes, tasks, files)

The main Introspection API. Open a Runner against a runtime, spawn tasks, and stream their output; manage files and read conversations on the same Runner. AsyncIntrospectionClient is the recommended entry point — everything that touches the network is awaitable, and run output streams with async for:

import asyncio

from introspection_sdk import AsyncIntrospectionClient


async def main() -> None:
    async with AsyncIntrospectionClient() as client:  # token from INTROSPECTION_TOKEN
        runner = await client.runtimes("customer-agent").run()

        async with runner:
            run = await runner.tasks.start(prompt="Say hello in one sentence.")

            async for event in run.stream():
                print(event.model_dump_json(by_alias=True, exclude_none=True))


asyncio.run(main())

A Runner exposes three DP-bound namespaces side by side: runner.tasks, runner.files, and the read-only runner.conversations. The conversations namespace lists conversation summaries (runner.conversations.list()), loads the latest LLM turn of a conversation as a Responses-API-style view (await runner.conversations.retrieve(conversation_id)), and walks a conversation's per-turn items (runner.conversations.items.list(...)).

Every list() returns an AsyncPager: async for it to stream every item across pages (fetched lazily), or await it for the first page with its envelope metadata (counts, cursors):

# Stream every summary across all pages.
async for summary in runner.conversations.list(limit=20):
    response = await runner.conversations.retrieve(
        summary.conversation_id or summary.trace_id
    )
    if response is not None:
        print(response.model, len(response.input_messages))

# Or just the first page, with totals.
first = await runner.files.list(include_total=True)
print(first.total_count, len(first.records))

See examples/api/async_runtimes.py for an end-to-end walkthrough.

Service-account (machine) auth

A long-lived INTROSPECTION_TOKEN is the simplest credential. For headless / CI callers that should not ship a static key, authenticate as a confidential service-account Application instead — from_service_account mints a short-lived, project-scoped token via the OAuth client_credentials grant and wires it in, so the runtime flow is unchanged:

from introspection_sdk import IntrospectionClient

client = IntrospectionClient.from_service_account(
    client_id="intro_app_…",      # confidential Application
    client_secret="intro_sk_…",   # minted once, kept server-side
    project="my-project",         # slug or UUID; the token is project-scoped
)
runner = client.runtimes("customer-agent").run()

The token is not auto-refreshed — re-mint once it expires (AsyncIntrospectionClient.from_service_account is the awaitable twin).

When you're a server broker handing credentials to a browser client, mint the token directly to also read dp_url (the Data Plane endpoint the Control Plane resolved for the project) and resolve the runtime slug to a concrete runtime_id — return { token, runtime_id, dp_url } so the browser SDK talks to the Data Plane without a hardcoded URL:

from introspection_sdk import IntrospectionClient, service_account_token

token = service_account_token(
    client_id="intro_app_…",
    client_secret="intro_sk_…",
    project="my-project",
)
client = IntrospectionClient(token=token.access_token)
runtime = client.runtimes.resolve("customer-agent")
# -> hand { token.access_token, runtime.id, token.dp_url } to the browser

token_exchange (RFC 8693 partner-IdP federation) and authorization_code_token (PKCE hosted-login callback) are the matching server-side helpers for end-user auth — each returns the same OAuthToken shape, carrying dp_url. See examples/api/service_account.py.

Sync client

Not on asyncio? IntrospectionClient is the synchronous twin with an identical surface — drop the awaits, use for instead of async for, and with instead of async with (examples/api/runtimes.py):

from introspection_sdk import IntrospectionClient

client = IntrospectionClient()  # token from INTROSPECTION_TOKEN
runner = client.runtimes("customer-agent").run()

run = runner.tasks.start(prompt="Say hello in one sentence.")
for event in run.stream():
    print(event.model_dump_json(by_alias=True, exclude_none=True))

runner.close()
client.shutdown()

OpenTelemetry (analytics & tracing)

Two optional OTel-based surfaces live behind the [otel] extra, independent of the Introspection API above:

pip install 'introspection-sdk[otel]'

• Analytics events — track / feedback / identify via IntrospectionLogs.
• Traces — auto-instrument Anthropic, Gemini, OpenAI Agents, Claude Agent, LangChain, and Logfire with a single introspection_sdk.init().

Both are documented in docs/otel.md; advanced/manual wiring lives in docs/advanced.md. For complete integration patterns (including dual-export with Arize, Langfuse, Braintrust, and LangSmith) see examples/.

Environment variables

# Introspection API (IntrospectionClient / AsyncIntrospectionClient)
export INTROSPECTION_TOKEN="intro_xxx"
export INTROSPECTION_BASE_API_URL="https://api.introspection.dev"   # optional
# The project is scoped by the API key. Pass project per call only to override
# it with a slug or UUID.

# OTel (IntrospectionLogs + span processors + instrumentors) — see docs/otel.md
export INTROSPECTION_BASE_OTEL_URL="https://otel.introspection.dev" # optional
export INTROSPECTION_SERVICE_NAME="my-service"                      # optional
