# Cohere Skill Pack

> 24 production-ready Claude Code skills for Cohere API v2 — Chat, Embed, Rerank, Classify, RAG, and tool-use agents.

## What This Covers

Every skill uses **real Cohere API v2 code**: `CohereClientV2` from `cohere-ai`, actual model IDs (`command-a-03-2025`, `embed-v4.0`, `rerank-v3.5`), real streaming events (`content-delta`, `citation-start`, `tool-call-start`), real error types (`CohereError`, `CohereTimeoutError`), and real rate limits (trial: 20 calls/min, production: 1000 calls/min).

## Installation

```bash
/plugin install cohere-pack@claude-code-plugins-plus
```

## Usage

Skills trigger automatically when you discuss Cohere topics:

- "Set up Cohere in my project" -> `cohere-install-auth`
- "Build a RAG pipeline with Cohere" -> `cohere-core-workflow-a`
- "Create a Cohere agent with tools" -> `cohere-core-workflow-b`
- "Fix this Cohere error" -> `cohere-common-errors`
- "Migrate from OpenAI to Cohere" -> `cohere-migration-deep-dive`
