Memory

Structure

• memory/MEMORY.md — Long-term facts (preferences, project context, relationships). Always loaded into your context.
• memory/HISTORY.md — Append-only event log. NOT loaded into context; search it with grep when you need to recall past events.

Search Past Events

Use GrepFiles to search HISTORY.md (cross-platform, no shell dependency):

GrepFiles(pattern="keyword", path="memory", include="HISTORY.md")

Regex patterns work too — e.g. pattern="meeting|deadline|project" matches any of those words.

For advanced search (e.g. context lines), use Exec with shell grep:

grep -i -C 3 "keyword" "memory/HISTORY.md"

Always search HISTORY.md when the user asks about past events, decisions, or conversations that aren't covered by MEMORY.md.

When to Update MEMORY.md

Write important facts to MEMORY.md immediately when you learn them:

• User preferences ("I prefer dark mode", "call me Alex")
• Project context ("The API uses OAuth2", "deploy target is AWS")
• Key relationships ("Alice is the project lead")
• Recurring instructions ("Always write tests before merging")

Use EditFile or WriteFile to update MEMORY.md.

Auto-consolidation

Old conversations are automatically summarized: long-term facts are extracted to MEMORY.md, and event entries are appended to HISTORY.md.
