Braintrust plugins for Codex

This repository is generated. It is built from braintrustdata/braintrust-coding-agent-plugins. Don't edit files here — make changes and file issues in that repository, and they will be rebuilt into this one.

This marketplace contains two independently opt-in plugins:

• Braintrust, braintrust@braintrust-codex-plugins: hosted MCP tools with OAuth. No bt dependency or tracing hooks. See the MCP installation and endpoint guide.
• Trace Codex, trace-codex@braintrust-codex-plugins: session tracing via bt.

For MCP, add this marketplace and select Braintrust:

codex plugin marketplace add braintrustdata/braintrust-codex-plugin
codex plugin add braintrust@braintrust-codex-plugins

The GitHub package connects to NA (US). EU and custom deployments require an admin-configured local/team copy; GitHub installs do not inherit public portal template settings. The planned public-directory listing uses one template, pending OpenAI eligibility and endpoint-template confirmation. Its concrete NA review URL is not a verified install-time default.

The sections below describe optional tracing setup only.

Quickstart

Install Codex and the Braintrust CLI, then run:

bt login
bt trace enable codex --project my-coding-agent

Setup adds the published marketplace, installs the plugin, and saves routing settings in ~/.codex/braintrust.json. Use --profile or --org to select a Braintrust profile or organization. Restart Codex after setup and approve the Braintrust hook through /hooks when prompted.

What is captured

The daemon builds session, turn, LLM, and tool spans from Codex hooks and transcripts, including available usage, compaction, and subagent activity. The plugin forwards events locally; bt owns authentication and delivery.

One-off runs and transcript import

bt trace run --project my-coding-agent codex -- exec "summarize this repository"
bt trace import codex SESSION_ID
bt trace import codex SESSION_ID --attach

run leaves your saved settings alone. import reads a saved transcript; --attach follows it until Ctrl-C. Imports include only what the agent recorded.

Manage tracing

bt trace doctor codex
bt trace status
bt trace update codex
bt trace disable codex

See the tracing plugin guide for hook behavior, metadata, and tags. MCP sign-in and bt tracing sign-in are independent.
