## What it does

AI agents lack direct visibility into cluster state beyond what fits in their prompt context. This package provides step-by-step guidance so Claude Code can configure `mirrord.json`, steal or mirror traffic, and connect local application instances directly to Kubernetes pods.

No executable binaries run during installation. The skills operate purely as instructions that direct the agent to invoke `mirrord`, `kubectl`, and `helm`. Without a working `kubeconfig` and local cluster tools, the agent cannot execute any cluster actions.

The workflows cover multi-service debugging, preview environments, and splitting streams for Kafka and Temporal. Claude Code can also inject artificial network latency to test service timeouts or locate HTTP headers that survive multi-hop propagation.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install mirrord-agent-skills@claude-community
```

## When to use it
- connect local processes to a Kubernetes cluster with mirrord
- generate and validate mirrord.json configurations
- isolate Kafka queues and Temporal tasks for local workers
- test network resilience by injecting latency and connection errors

## Example prompts
- Help me run my Node service locally against our staging Kubernetes cluster using mirrord.
- Create a mirrord.json to steal traffic from pod/api-server matching my baggage header.
- Configure queue splitting for the orders.created Kafka topic so only my messages reach my machine.

# mirrord Agent Skills

Twelve [Agent Skills](https://agentskills.io/home) that close the AI agent feedback loop on Kubernetes: real env vars, real DNS, real network, real traffic, real databases, real Kafka, real Temporal task queues, real preview environments, multi-service local sessions, real failure conditions, the header propagation that lets a session follow a request across services and queues, and the discovery of what your cluster already propagates so a filter can use it. Built by [MetalBear](https://metalbear.com/) to be used with [mirrord](https://metalbear.com/mirrord/).

AI coding agents work from what's in their context window. Your Kubernetes cluster is full of state that isn't. These skills teach your agent how and when to use mirrord so the code it writes against your live infrastructure stops being informed guessing.

## Installation

### Claude Code

```bash
/plugin marketplace add metalbear-co/skills
/plugin install mirrord@mirrord-skills
```

### Codex

```bash
codex plugin marketplace add metalbear-co/skills
```

Then install the `mirrord` plugin from `/plugins`. All twelve skills come with it.

### OpenCode

OpenCode loads skills natively, so there's nothing to register — the skills just need to be on disk:

```bash
curl -fsSL https://raw.githubusercontent.com/metalbear-co/skills/main/install.sh | sh
```

That writes the twelve skill folders into `~/.config/opencode/skills/`. Restart OpenCode and they're available. Re-run it any time to update — it replaces the `mirrord-*` folders and leaves your other skills alone.

The same script serves any agent that reads a skills directory:

```bash
sh install.sh --agent codex     # ~/.agents/skills
sh install.sh --agent claude    # ~/.claude/skills
sh install.sh --dest <dir>      # anywhere else
```

### Cursor, Gemini, or any other [Agent Skills](https://agentskills.io)-compatible agent

```bash
npx skills add metalbear-co/skills
```

### GitHub Copilot, Cline, and other rules-file agents

The [`ports/`](./ports/) directory carries the same core content as drop-in rules files: copy [`ports/github-copilot/copilot-instructions.md`](./ports/github-copilot/copilot-instructions.md) into your repo's `.github/`, or [`ports/cline/.clinerules`](./ports/cline/.clinerules) into your repo root.

## The twelve skills

| Skill | What it does |
|-------|--------------|
| [mirrord-quickstart](./skills/mirrord-quickstart/) | Zero-to-first-session: install mirrord, find a target, run the first session. |
| [mirrord-config](./skills/mirrord-config/) | Generate and validate `mirrord.json` for any workflow (steal, mirror, env injection, file system hooks). |
| [mirrord-operator](./skills/mirrord-operator/) | Install and configure the mirrord Operator for team-scale concurrent shared-cluster use, including agent-started trials on clusters with no license yet. |
| [mirrord-ci](./skills/mirrord-ci/) | Wire mirrord into CI pipelines so integration tests hit real cluster services. |
| [mirrord-db-branching](./skills/mirrord-db-branching/) | Per-developer copy-on-write database branches off your staging DB. |
| [mirrord-kafka](./skills/mirrord-kafka/) | Kafka queue splitting so each developer consumes a private slice of a real topic. |
| [mirrord-temporal](./skills/mirrord-temporal/) | Temporal task queue splitting so each developer's local worker gets only the workflow and activity tasks matching their filter. |
| [mirrord-prev-env](./skills/mirrord-prev-env/) | Preview environments: deploy a built image as an isolated, traffic-filtered pod in a shared cluster — ad hoc or per-PR in CI. |
| [mirrord-up](./skills/mirrord-up/) | Multiple concurrent local sessions from `mirrord-up.yaml` — compose-style multi-service debugging. |
| [mirrord-chaos](./skills/mirrord-chaos/) | Chaos testing: inject latency or connection errors into a session's outgoing traffic via per-session rules, interactively or in CI. |
