Observability for coding agents

Teams adopting AI coding agents need three things: to see what the agent did, to spend less doing it, or to use the agent to add observability to their own app.

You want to…	Use	What you get
See what the agent did. Read the conversation, check which tools ran, debug a bad run, share a session with a teammate.	Opik tracing, set up per agent	Every prompt, response and tool call, grouped into threads you can score, annotate and share.
Spend less doing it. Find where the tokens actually go, per user and per repo, then cut the waste.	Cost Intelligence	Token counts broken out across system prompt, tools, MCP servers, skills and memory, plus policy controls. Metadata only — never your code or conversations.
Add observability to your own app. Instrument your code, score outputs and run experiments from your coding agent.	Opik MCP server	`uvx opik mcp configure` registers the server and the Opik skills with your agent.

Set up tracing for your agent

Each agent has its own way of getting sessions out. The Quick start column is the single step that does most of the work; the linked page has the full setup, endpoint modes and validation.

Agent	Path into Opik	Quick start	Content captured	Cost Intelligence
Claude Code	Opik plugin (recommended), or native OTel export (beta)	`/plugin install opik` inside Claude Code	Plugin: yes. OTel: redacted unless enabled	Supported
GitHub Copilot (VS Code, CLI)	Native OTel export	`github.copilot.chat.otel.enabled: true` plus the Opik endpoint	Off unless `captureContent` is enabled	Ask your account team
Cursor	Opik Cursor extension	Install the `Opik` extension and paste your API key	Yes	Supported
OpenAI Codex	Native OTel export (internal spans and `codex.*` events only)	An `[otel.trace_exporter.otlp-http]` table in `~/.codex/config.toml`	No. Prompt text and tokens go to the logs signal, which Opik does not ingest	Supported
Other agents (opencode, Gemini CLI, ...)	Native OTel export if the agent emits `gen_ai.*` spans	Point the agent's OTLP exporter at the Opik OTel endpoint	Depends on the agent	Not yet

Claude Code

Opik plugin (recommended) captures every turn with full content. Native OpenTelemetry export is available as a beta alternative.

GitHub Copilot

Native OpenTelemetry export from Copilot Chat in VS Code and from Copilot CLI. Enterprise managed settings can mandate it fleet-wide.

Cursor

Opik Cursor extension logs every conversation, with token usage and cost from your Cursor account.

OpenAI Codex

Native OpenTelemetry export configured in config.toml. Operational spans and events only; no prompt text, tokens or cost on the trace signal.
