// 作用：压缩 LLM 的 prompt 常量
// 关联：被 compact_messages 的 CallCompactLLM 调用
// 预期结果：提供系统提示、首次压缩提示、增量更新压缩提示

/// 压缩系统提示 —— 指导 LLM 只输出压缩摘要，不要继续对话
pub const SUMMARIZATION_SYSTEM_PROMPT: &str = "You are a context summarization assistant. Your task is to read a conversation between a user and an AI coding assistant, then produce a structured summary following the exact format specified.

Do NOT continue the conversation. Do NOT respond to any questions in the conversation. ONLY output the structured summary.";

/// 首次压缩提示 —— 压缩对话前缀
pub const TURN_PREFIX_SUMMARIZATION_PROMPT: &str = "This is the PREFIX of a turn that was too large to keep. The SUFFIX (recent work) is retained.

Summarize the prefix to provide context for the retained suffix:

## Original Request
[What did the user ask for in this turn?]

## Early Progress
- [Key decisions and work done in the prefix]

## Context for Suffix
- [Information needed to understand the retained recent work]

Be concise. Focus on what's needed to understand the kept suffix.";

/// 更新压缩提示 —— 对已有压缩摘要进行增量更新
pub const UPDATE_SUMMARIZATION_PROMPT: &str = "The messages above are NEW conversation messages to incorporate into the existing summary provided in <previous-summary> tags.

Update the existing structured summary with new information. RULES:
- PRESERVE all existing information from the previous summary
- ADD new progress, decisions, and context from the new messages
- UPDATE the Progress section: move items from \"In Progress\" to \"Done\" when completed
- UPDATE \"Next Steps\" based on what was accomplished
- PRESERVE exact file paths, function names, and error messages
- If something is no longer relevant, you may remove it

Use this EXACT format:

## Goal
[Preserve existing goals, add new ones if the task expanded]

## Constraints & Preferences
- [Preserve existing, add new ones discovered]

## Progress
### Done
- [x] [Include previously done items AND newly completed items]

### In Progress
- [ ] [Current work - update based on progress]

### Blocked
- [Current blockers - remove if resolved]

## Key Decisions
- **[Decision]**: [Brief rationale] (preserve all previous, add new)

## Next Steps
1. [Update based on current state]

## Critical Context
- [Preserve important context, add new if needed]

Keep each section concise. Preserve exact file paths, function names, and error messages.";
