Constant LIST_FORMAT_INSTRUCTIONS 

pub const LIST_FORMAT_INSTRUCTIONS: &str = r"
## URN Format

Rich URN encodes scope, namespace, and ID:
```
subcog://{scope}/{namespace}/{id}
```
Examples:
- `subcog://project/decisions/abc123...` - project-scoped decision
- `subcog://org/acme/patterns/def456...` - org-scoped pattern
- `subcog://acme/myrepo/learnings/ghi789...` - repo-scoped learning

## Output Formats

### Table Format (default)
Present results directly from `subcog_recall` output. Each line shows:
```
{n}. subcog://{scope}/{namespace}/{id} | {score} [{tags}]
   {content_summary}
```

Group by namespace with counts when helpful.

### Compact Format
```
subcog://{scope}/{namespace}/{id} [{tags}]
```

### Detailed Format
```
### subcog://{scope}/{namespace}/{id}
- **Score**: {score}
- **Tags**: tag1, tag2
- **Source**: {source}
- **Content**: {full_content}
```
