    click Agent href "../system-prompts/agent-prompt-pr-comments-slash-command.md" "PR Comments Agent"
```

**Prompt:** [agent-prompt-pr-comments-slash-command.md](../system-prompts/agent-prompt-pr-comments-slash-command.md)

```mermaid
flowchart LR
    Cmd["/review-pr"] --> Agent["PR Review Agent"]
    Agent --> Analyze["Analyze changes"]

    click Agent href "../system-prompts/agent-prompt-review-pr-slash-command.md" "PR Review Agent"
```

**Prompt:** [agent-prompt-review-pr-slash-command.md](../system-prompts/agent-prompt-review-pr-slash-command.md)
