Module context_template 

Context template models.

Provides data structures for user-defined context templates that format memories and statistics for hooks and MCP tool responses.

Variable Types

Context templates support two types of variables:

1. Auto-variables: Automatically populated from memory context

   • {{memories}} - List of memories for iteration
   • {{memory.id}}, {{memory.content}}, etc. - Individual memory fields (in iteration)
   • {{statistics}} - Memory statistics object
   • {{total_count}}, {{namespace_counts}} - Statistics fields

2. User-variables: Custom variables provided at render time

   • Any {{variable}} not in the auto-variable list

Iteration Syntax

Templates support iteration over collections using {{#each}}...{{/each}}:

{{#each memories}}
- **{{memory.namespace}}**: {{memory.content}}
{{/each}}
