Use when adding tracing, structured logging, metrics, or monitoring to a FrontMCP server. Covers zero-config OpenTelemetry distributed tracing across all flows; the this.telemetry API for custom spans, events, and attributes in tools, plugins, agents, and skills; structured JSON logging with trace correlation and configurable sinks (Winston, Pino, stdout); the off-by-default /metrics endpoint (process and framework metrics, Prometheus-compatible); event-loop stall detection that names the calls…

Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'frontmcp-observability' ] || [ -L ~/.agents/skills/'frontmcp-observability' ]; then echo 'A skill folder named frontmcp-observability already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/agentfront/frontmcp' "$d" && git -C "$d" checkout --quiet 'cadd045f5f9f5a3260c23264ae771b4a1ef4de49' -- 'libs/skills/catalog/frontmcp-observability' && mkdir -p ~/.agents/skills && cp -R "$d"/'libs/skills/catalog/frontmcp-observability' ~/.agents/skills/'frontmcp-observability' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'frontmcp-observability' ~/.claude/skills/'frontmcp-observability' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
