Makes a codebase propagate W3C baggage (the `baggage` header carrying `mirrord-session=<key>`) end to end, so mirrord HTTP filters, preview environments, and queue splitting can route a whole request chain to one developer's session. Detects existing OpenTelemetry, Datadog, or other tracing that can already propagate baggage and enables it; otherwise adds a small propagation layer. Covers inbound/outbound HTTP and gRPC, publishing to and consuming from Kafka, RabbitMQ, SQS/SNS, GCP Pub/Sub, Azu…

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'mirrord-header-propagation' ] || [ -L ~/.agents/skills/'mirrord-header-propagation' ]; then echo 'A skill folder named mirrord-header-propagation already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/metalbear-co/mirrord' "$d" && git -C "$d" checkout --quiet '0dc6e26fb6ded4800832d9c0647891235a252ed7' -- 'mirrord/mcp/corpus/skills/mirrord-header-propagation' && mkdir -p ~/.agents/skills && cp -R "$d"/'mirrord/mcp/corpus/skills/mirrord-header-propagation' ~/.agents/skills/'mirrord-header-propagation' && 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/'mirrord-header-propagation' ~/.claude/skills/'mirrord-header-propagation' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
