🔭 OpenClaw Opik Observability Plugin

Official plugin for OpenClaw that exports agent traces to

Opik for observability and monitoring.

Why This Plugin

Opik is a leading open-source LLM and agent observability, tracing, evaluation and optimization platform. @opik/opik-openclaw adds native Opik tracing for OpenClaw runs:

• LLM request/response spans
• Sub-agent request/response spans
• Tool call spans with inputs, outputs, and errors
• Run-level finalize metadata
• Usage and cost metadata

The plugin runs inside the OpenClaw Gateway process. If your gateway is remote, install and configure the plugin on that host.

Install and first run

Prerequisites:

• OpenClaw >=2026.3.2
• Node.js >=22.12.0
• npm >=10

1. Install the plugin in OpenClaw

openclaw plugins install clawhub:@opik/opik-openclaw

And for older version of OpenClaw <2023.3.23 you can install the npm package using:

openclaw plugins install @opik/opik-openclaw

If the Gateway is already running, restart it after install.

2. Configure the plugin

openclaw opik configure

The setup wizard validates endpoint and credentials, then writes config under plugins.entries.opik-openclaw. If you choose Opik Cloud and do not have an account yet, the wizard now points you to the free signup flow before asking for an API key.

3. Check effective settings

openclaw opik status

4. Send a test message

openclaw gateway run
openclaw message send "hello from openclaw"

Then confirm traces in your Opik project.

Configuration

Recommended config shape

{
  "plugins": {
    "entries": {
      "opik-openclaw": {
        "enabled": true,
        "hooks": {
          "allowConversationAccess": true
        },
        "config": {
          // base configuration
          "enabled": true,
          "apiKey": "your-api-key",
          "apiUrl": "https://www.comet.com/opik/api",
          "projectName": "openclaw",
          "workspaceName": "default",
          // optional advanced configuration
          "tags": ["openclaw"],
          "toolResultPersistSanitizeEnabled": false,
          "staleTraceCleanupEnabled": true,
          "staleTraceTimeoutMs": 300000,
          "staleSweepIntervalMs": 60000,
          "flushRetryCount": 2,
          "flushRetryBaseDelayMs": 250
        }
      }
    }
  }
}

Plugin trust allowlist

OpenClaw warns when plugins.allow is empty and a community plugin is discovered. Pin trusted plugins explicitly:

{
  "plugins": {
    "allow": ["opik-openclaw"]
  }
}

Because Opik traces LLM prompts, responses, tools, and agent finalization events, non-bundled installs also need explicit conversation hook access:

{
  "plugins": {
    "entries": {
      "opik-openclaw": {
        "hooks": {
          "allowConversationAccess": true
        }
      }
    }
  }
}

Environment fallbacks

• OPIK_API_KEY
• OPIK_URL_OVERRIDE
• OPIK_PROJECT_NAME
• OPIK_WORKSPACE

Transcript safety default

toolResultPersistSanitizeEnabled is disabled by default. When enabled, the plugin rewrites local image refs in persisted tool transcript messages via tool_result_persist.

CLI commands

Command	Description
openclaw plugins install @opik/opik-openclaw	Install plugin package
openclaw opik configure	Interactive setup wizard
openclaw opik status	Print effective Opik configuration

Event mapping

OpenClaw event	Opik entity	Notes
llm_input	trace + llm span	starts trace and llm span
llm_output	llm span update/end	writes usage/output and closes span
before_tool_call	tool span start	captures tool name + input
after_tool_call	tool span update/end	captures output/error + duration
subagent_spawning	subagent span start	starts subagent lifecycle span on requester trace
subagent_spawned	subagent span update	enriches subagent span with run metadata
subagent_ended	subagent span update/end	finalizes subagent span with outcome/error
agent_end	trace finalize	closes pending spans and trace

Known limitation

No OpenClaw core changes are included in this repository and relies on native hooks within the OpenClaw ecosystem.

Development

Prerequisites:

• Node.js >=22.12.0
• npm >=10

npm ci
npm run build
npm run lint
npm run typecheck
npm run test
npm run smoke

Packaging

The package publishes built JavaScript for installed OpenClaw runtime loads while keeping TypeScript source metadata for development and older OpenClaw fallback loads. openclaw.extensions points at ./index.ts; openclaw.runtimeExtensions points at ./dist/index.js. ClawHub also requires explicit openclaw.compat.pluginApi and openclaw.build.openclawVersion metadata. npm pack and npm publish run npm run build through prepack, and npm run pack:check verifies the tarball contract. Pull requests also dry-run the ClawHub package publish workflow, and GitHub releases publish the validated package to both npm and ClawHub.

Optional live gateway E2E:

npm run test:live

Notes:

• uses an isolated .artifacts/live-e2e/<run-id>/home/.openclaw so it does not touch your normal OpenClaw config
• OPIK_API_KEY, OPIK_URL_OVERRIDE, OPIK_PROJECT_NAME, and OPIK_WORKSPACE win if set in env
• otherwise it reuses ~/.openclaw/openclaw.json -> plugins.entries.opik-openclaw.config for apiUrl / apiKey / project / workspace
• set OPENCLAW_LIVE_USE_HOST_OPIK_CONFIG=0 to disable reading host plugin config and require explicit env-only Opik settings
• still requires OPENAI_API_KEY in env for the real model call
• packs and installs the current plugin build into a fresh OpenClaw home
• falls back to npx openclaw@${OPENCLAW_LIVE_OPENCLAW_VERSION:-latest} when openclaw is not already on your PATH
• override the live model with OPENCLAW_LIVE_MODEL if gpt-4o-mini is not what you want to exercise
