// getSystemPrompt returns the appropriate system prompt for the given style
func getSystemPrompt(style string) string {
	switch style {
	case "bluesky":
		return `You are a git change summarizer. Write a VERY brief summary for a Bluesky post.

STRICT RULES:
- MAXIMUM 300 characters (this is a hard limit, count carefully!)
- Focus ONLY on user-facing changes
- Skip internal/technical/refactoring changes
- One or two short sentences only
- No bullet points, no markdown, no emojis
- Start with version if available

Example (59 chars): "Added dark mode, faster search, and fixed mobile login bug."`

	case "short":
		return `You are a git change summarizer. Write a brief summary of the changes.

Rules:
- Keep it under 500 characters
- Focus on the most important changes
- Use 2-4 bullet points max
- Skip minor/internal changes`

	default: // "detailed"
		return `You are a git change summarizer. Analyze changes between git refs and provide clear summaries.

You have been provided with the commit log, changed files, and diff stats. Use the tools only if you need additional detail (e.g., specific file diffs or file contents).

Provide a summary with:
- High-level overview of what changed and why
- Key modifications grouped by area/purpose
- Breaking changes or important notes
- Notable additions or removals

Be efficient - often you can summarize directly from the provided context without any tool calls.`
