Quick Start: Minimal Memory

Only 4 fields are required. Everything else is optional.

id: 550e8400-e29b-41d4-a716-446655440000
title: "Human-readable title"

# Title

Content here.

That's it. Add optional fields only when you need them.

File Naming

{slug}.memory.md

slug: URL-safe title, lowercase, max 50 chars
UUID is stored only in the frontmatter id: field
If a file with the same slug already exists, content is merged

# Memory Title

Content in markdown format.

## Relationships

- relates-to [[other-memory-id]]
- supersedes [[old-memory-id]]
- derived-from [[source-memory-id]]

Cognitive Memory Types

Type	Use For	Namespace Pattern
`semantic`	Facts, specs, configs, definitions	`_semantic/{subtype}/project`
`episodic`	Debug sessions, incidents, discoveries	`_episodic/{subtype}/project`
`procedural`	Runbooks, how-to guides, workflows	`_procedural/{subtype}/project`

Relationship Syntax

Add a ## Relationships section at the end of any memory body using - {type} [[{memory-id}]] syntax.

Type	Meaning
`relates-to`	General association
`supersedes`	Replaces older memory
`derived-from`	Built upon another memory
`contradicts`	Conflicts with another memory
`implements`	Realizes a design/decision

Quick Templates

Generate REAL values for ids and timestamps. Run uuidgen | tr '[:upper:]' '[:lower:]' and date -u +"%Y-%m-%dT%H:%M:%SZ" before creating any memory. NEVER leave placeholders.

See Quick Start above for the minimal template. Below are additional templates for common memory types.
