SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Project insights and past solutions get lost across chat sessions and scattered notes, forcing teams to repeatedly solve the same problems. This skill centralizes everything the AI has learned about your project into a searchable, maintainable knowledge base.

Core Features & Use Cases

  • Learning Review: Instantly see the most recent 20 learnings grouped by type to catch up on project history.
  • Semantic Search: Find specific insights, pitfalls, or patterns using natural language queries across all recorded learnings.
  • Staleness Pruning: Automatically flag learnings that reference deleted files or contradict newer entries.
  • Export & Stats: Export learnings for external sharing and view statistics about your team's knowledge base.
  • Proactive Suggestions: The skill surfaces relevant past learnings when you encounter similar problems.

Quick Start

Use the learn skill to review recent project learnings and search for past patterns related to the current branch.

FAQPage Schema
How do I recover project knowledge and past learnings across different development sessions?

To recover project knowledge across sessions, you need a context recovery tool that performs semantic search on local learnings JSONL files. This allows you to instantly recall past patterns, review recent insights grouped by type, and avoid repeating solved problems.

How do I search for past development patterns using natural language queries?

You can search for past development patterns using natural language queries through semantic search functionality. This mechanism scans all recorded project learnings to find specific insights, pitfalls, or solutions without requiring exact keyword matches.

How do I detect stale project knowledge that references deleted files?

To detect stale project knowledge referencing deleted files, use staleness pruning functionality. This mechanism automatically flags outdated learnings that reference deleted files or contradict newer entries, keeping your institutional knowledge base maintainable.

Can I export project learnings for external team sharing?

Yes, you can export project learnings for external sharing. The export feature extracts your centralized development insights from the local knowledge base, allowing you to distribute institutional knowledge and view statistics about captured sessions.

Do I need local gstack analytics directories to review captured project insights?

Yes, you need access to local gstack analytics directories and learnings JSONL files to review captured insights. This environment setup is required to perform semantic search, staleness detection, and cross-session context recovery.

What is the best way to maintain institutional knowledge in AI-assisted development environments?

The best way to maintain institutional knowledge in AI-assisted environments is centralizing insights into a searchable knowledge base. This approach surfaces relevant past learnings proactively when similar problems occur, preventing knowledge loss across scattered chat sessions.
