LlamaIndex
Data-first agent framework.
Originally a retrieval-focused framework, now with first-class agent support. Strong fit for agents whose primary job is reasoning over proprietary data sources.

What “Beta” means for LlamaIndex
The integration path is built and tested. Real customers can attach now, but expect minor breaking changes until the 1.0 contract freeze.
How it attaches
SDK / Library.
Install the trustvice-actor-llamaindex package and call witness.attach() once during agent initialisation.
Install the Trustvice adapter package from npm, PyPI, or cargo and call witness.attach(agent) in your application.
pip install trustvice-actor-llamaindex
- 1
Install the adapter
Add trustvice-actor-llamaindex to your project from PyPI.
- 2
Issue a workspace API key
Generate a twk_-prefixed key in the dashboard under Settings → API Keys, scoped to the workspace and environment this agent's data should land in.
- 3
Attach the witness
Call witness.attach(agent) once when you initialise your LlamaIndex agent. The adapter registers the framework callbacks, handles retries, and performs the workspace handshake.
- 4
Verify
Trigger one agent run. The dashboard's Witness page shows the canonical record within ~1 second of the agent emitting it.
pip install trustvice-actor-llamaindex
Coverage
4 event types captured.
agent.invocationEvery top-level agent run — the input, the resolved output, timing, and token usage.
tool.callEach tool / function the agent invokes, with arguments and the returned result.
memory.writeWrites to the agent's persistent memory store, so state changes are auditable.
sub_agent.spawnSub-agents the orchestrator spawns, captured with their parent lineage.
The full pattern guide
SDK / Library — end to end.
Every framework on this pattern shares the same platform-side spine, endpoints, and gotchas. The pattern guide covers them in full.
