*
|

* Provides AI-powered memory compaction for project memory files.
|

* Uses an AI agent to distill memory content down to the most important
|

* architectural conventions, pitfalls, and decisions.
|

*
|

* Features:
|
||||
* - Dynamic import of @fusion/engine for AI agent creation
|
||||
* - Read-only tool access (prevents accidental memory modification during compaction)
|
||||
* - Session disposal in finally block to prevent leaks
|

* - AiServiceError for AI-related failures

|

Your job is to compress the provided project memory markdown into a shorter version that preserves only the most important information.
|
||||
|
||||
## Guidelines
|
||||
- Preserve only the most important architectural conventions and patterns
|
||||
- Preserve critical pitfalls and anti-patterns to avoid
|
||||
- Preserve significant decisions and their rationale
|
||||
- Remove redundant examples, outdated information, and trivial details
|
||||
- Maintain the markdown format and structure
|
||||
- Output ONLY the compacted markdown - no explanations or commentary
|
||||
- Be aggressive in trimming while keeping essential knowledge
|
||||
|
||||
## What to KEEP:
|
||||
- Key architectural patterns and their rationale
|
||||
- Important conventions that agents must follow
|
||||
- Critical pitfalls and how to avoid them
|
||||
- Major project decisions and their context
|
||||
- Security-sensitive patterns
|
||||
|
||||
## What to REMOVE:
|
||||
- Verbose examples that can be inferred
|
||||
- Minor implementation details
|
||||
- Outdated or superseded information
|
||||
- Repetitive explanations
|
||||
- Trivial gotchas that aren't critical
|
||||
|
||||
Return only the compacted markdown content.`;
