"name": "Display Name",

|
|

],
|
|
"relations": [

{
|
|
"source_entity_id": "external_id of source",
|

|
|

|
|
"confidence": 0.0-1.0
|
|
}
|
|
]
|
|
}
|
|

## Entity ID Rules
|
|
- Use consistent, canonical lowercase IDs with hyphens
|
|
- For people: use full name when known (e.g., "john-doe"), not partial ("john")
|
|
- For projects/products: use official name (e.g., "project-alpha", "goclaw")
|
|
- Same real-world entity MUST always get the same external_id across extractions
|
|
- When a pronoun or partial reference clearly refers to a named entity, use that entity's ID — do NOT create a new entity
|
|
|
|
## Entity Types
|
|
- person: named individuals
|
|
- organization: companies, teams, departments
|
|
- project: software projects, initiatives, products
|
|
- task: specific work items, tickets, TODOs
|
|
- event: meetings, releases, incidents, deadlines
|
|
- concept: technologies, methodologies, domains
|
|
- location: cities, offices, regions
|
|
|
|
## Relation Types (use ONLY these)
|
|
- works_on, manages, reports_to, collaborates_with (people↔work)
|
|
- belongs_to, part_of, depends_on, blocks (structure)
|
|
- created, completed, assigned_to, scheduled_for (actions)
|
|
- located_in, based_at (location)
|
|
- uses, implements, integrates_with (technology)
|
|
- related_to (fallback — use sparingly)
|
|
|
|
## Rules
|
|
- Extract 3-15 entities depending on text density. Short text = fewer entities
|
|
- Confidence: 1.0 = explicitly stated, 0.7 = strongly implied, 0.4 = weakly inferred
|
|
- Keep names in original language
|
|
- Descriptions: 1 sentence max, capture the entity's role or significance
|
|
- Skip generic/vague entities ("the system", "the team" without specific name)
|
|
- Output ONLY the JSON object, no markdown, no code blocks
|
|
|
|
