SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you organize long-term facts and quickly search past events so you can act with context instead of starting from scratch.

Core Features & Use Cases

Two-layer memory system: Long-term facts live in MEMORY.md while an append-only event log lives in HISTORY.md.
Greppable event recall: Search HISTORY.md by keyword(s) using grep-style matching to quickly find relevant prior actions, decisions, or events.
Automatic consolidation: Older conversations get summarized into HISTORY.md, and stable long-term facts are extracted into MEMORY.md without manual management.

Quick Start

Use grep to search the event log by typing a case-insensitive keyword query against memory/HISTORY.md (optionally combining patterns with an extended regex query) to surface relevant past events.

FAQPage Schema

How do I recall past context and search event logs with grep?▼

You can recall past context by running case-insensitive grep keyword queries against memory/HISTORY.md, optionally combining patterns with extended regex, to surface relevant prior actions and decisions.

What is the best way to persist user preferences and project context across sessions?▼

To persist project context, maintain memory/MEMORY.md for stable long-term facts and memory/HISTORY.md for chronological events, ensuring consistent entry formatting for reliable retrieval.

Does this approach require manual management of long-term facts and event history?▼

No, older conversations get summarized into HISTORY.md automatically, and stable long-term facts are extracted into MEMORY.md without manual management, reducing maintenance overhead.

Can I use combined pattern queries to find specific deadlines in the event log?▼

Yes, you can search for deadlines or meetings in HISTORY.md using extended regex queries to combine multiple keyword patterns, enabling precise and rapid retrieval of past events.

What are the limitations of using grep for workspace context retrieval?▼

Grep-based retrieval depends on consistent entry formatting within HISTORY.md and MEMORY.md; without standardized keywords or formatting, matching accuracy for past events may degrade.
