Sets up coding-agent observability with Rius: every Claude Code, Codex or Cursor session becomes an OpenTelemetry trace with model calls, tokens, cost, tool calls and subagents, per developer and per session. Use when the user asks how to track their own or their team's Claude Code, Codex or Cursor usage and cost, see what Claude Code is doing, find Claude Code token spend per developer, monitor or trace coding agents, or observe OpenHands. Not for instrumenting an agent you are building; use…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Coding-agent observability with Rius **Rius** (by GlassFlow) traces coding agents. The `rius` plugin from `glassflow/rius-coding-agents` turns each Claude Code session into one trace: turns, every model call with its model and token counts (cache reads and writes included), tool calls, and the subagents Claude Code started, as a waterfall that fills in while the session runs. Rius prices the tokens, so the console shows cost per session, per agent and per developer. The same repo traces Codex and Cursor (both beta), and OpenHands sends traces to Rius with no plugin at all. Docs: https://docs.glassflow.ai/rius/guides/claude-code-plugin ## Operating rules - Say what is about to run, run it, and show the result. - The sign-in and enable commands (`/rius:login`, `/rius:enable-here` and their Codex and Cursor equivalents) can only be run by the user. Tell the user to type them; never run them or their scripts yourself. - Never paste an API key into a file or the chat. The plugin stores the key it mints itself. - Whether a folder sends prompts and file contents is the user's choice. Recommend the default (structure only) and let the user decide. ## 1. Which agent …

How to install
mdr add glassflow/rius-coding-agents/coding-agent-observability@sha256:b377919c5919e28dThe line at the top of this page pins the label git:20261020.e526d3b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
