# Linkerd Patterns

Production patterns for Linkerd service mesh - the lightweight, security-first service mesh for Kubernetes.

## Do not use this skill when

- The task is unrelated to linkerd patterns
- You need a different domain or tool outside this scope

## Instructions

- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
- If detailed examples are required, open `resources/implementation-playbook.md`.

## Use this skill when

- Setting up a lightweight service mesh
- Implementing automatic mTLS
- Configuring traffic splits for canary deployments
- Setting up service profiles for per-route metrics
- Implementing retries and timeouts
- Multi-cluster service mesh
