Core — AI skill for Claude Code
Agentic AI monitoring and observability — OTEL traces and local log files from Copilot, Claude Code, Codex, and OpenCode.
How to install Core
This entry records only its repository, not the path inside it, so there is no
exact command to give. Open traceroost/core and copy the folder into
~/.claude/skills/, or the file into ~/.claude/agents/.
What Core does
Agentic AI monitoring and observability — OTEL traces and local log files from Copilot, Claude Code, Codex, and OpenCode. Token usage, cost, summaries, and efficiency insights. VS Code extension, npx, and Docker.

Local monitoring and observability for agentic AI coding tools — see what's actually happening inside each run. Nothing leaves your machine.
TraceRoost receives **OpenTelemetry traces** from Copilot, Claude Code, and Codex in real time, giving you span timing, time-to-first-token, per-tool latency, and file diffs. It also reads the **local log files** each agent writes automatically — including OpenCode's **SQLite database** — as a zero-config fallback that backfills history from before you set anything up. Both sources appear in one dashboard; OTEL takes precedence when available.
Two things it does that a usage dashboard doesn't:
- Catches agents that are stuck. Ten named loop and malfunction patterns — repeated tool calls, oscillating edits, recurring errors, runaway scope, hallucinated dependencies, unverified test runs, and more — each with a correction prompt you can paste straight into the session. See the full list →
- Tells you what to fix in your instructions file. The Advisor reads across traces and suggests concrete additions to your CLAUDE.md or AGENTS.md — including hot files the agent rediscovers from scratch on every run. More →
**Quick start:**
npx traceroost@latest
Open — that's it. Running it in a terminal only lasts until you close it, though: if TraceRoost isn't running when an agent sends OTEL data, that
