create-bkn

description

Guides creation of BKN (Business Knowledge Network) definition files following v2.0.1 spec. Covers network, object_type, relation_type, action_type, concept_group. Use when creating knowledge networks, BKN files, object types, relation types, action types, concept groups, or when user asks to model business knowledge in BKN format. When the openbkn skill is also loaded, use it to run the openbkn CLI (auth, bkn push) after files exist.

Create BKN

Generate well-formed BKN directories (Markdown + YAML frontmatter) per v2.0.1.

Works with the openbkn skill

create-bkn authors the .bkn tree; the openbkn skill runs openbkn auth login and openbkn bkn push / pull after files exist.

What is BKN

BKN is Markdown + YAML frontmatter for schema; one file per definition under typed subfolders. Details (sections, required tables, types) live in references/SPECIFICATION.llm.md.

Directory layout

{network_dir}/
├── SKILL.md
├── network.bkn
├── CHECKSUM                 # optional; SDK may generate

└── data/                    # optional CSV instance data

Workflow

1. Gather requirements — objects, relations, actions, optional concept groups
2. Read spec — references/SPECIFICATION.llm.md (format rules, sections, frontmatter types)
3. Pick templates — copy/adapt from assets/templates/ (network_type.bkn.template, object_type.bkn.template, …)
4. Create network.bkn — root file; align with Network Overview
5. Create object_types/*.bkn — one file per object, {id}.bkn
6. Create relation_types/*.bkn — one file per relation
7. Create action_types/*.bkn — one file per action
8. Create concept_groups/*.bkn — optional
9. Update network.bkn — list all IDs in Network Overview
10. Add root SKILL.md in the BKN directory — same folder as network.bkn (this is not the create-bkn skill file); agent-facing guide for that network (see Delivered BKN: root SKILL.md)
11. Review (MUST) — cross-check Validation checklist and Business rules placement; fix IDs, cross-refs, headings
12. Validate (MUST) — openbkn bkn validate <dir> (see Validation)
13. Import (optional) — openbkn bkn push <dir>

Import (openbkn CLI)

Requires the openbkn CLI from @openbkn/bkn-sdk (npm install -g @openbkn/bkn-sdk; Node.js 22+). push uses tar; on macOS COPYFILE_DISABLE=1 is set by the tool.

• Platform auth — If you already have a valid token for the target platform (openbkn auth status), do not run openbkn auth login again. If not authenticated, run openbkn auth login <platform-url> first.
• BKN validation — If workflow step 12 (openbkn bkn validate <dir>) already succeeded for this directory, do not repeat validate before push unless you changed .bkn files. If you have not validated yet, run validate before push.

openbkn bkn push <dir> [--branch main] [-bd <business-domain>]

-bd / --biz-domain is optional. If you omit it, the CLI resolves the business domain automatically (saved platform config in ~/.bkn, otherwise bd_public).

Export: openbkn bkn pull <kn-id> [<dir>]. More subcommands: openbkn bkn --help (see the openbkn skill if loaded).

Validation

openbkn bkn validate <dir> — must pass before delivery or upload. It loads network.bkn and sibling .bkn files. Success prints counts; on failure fix .bkn files and re-run.

Per-type reference

Kind	Spec (section)	Template	Example (k8s)
Network	knowledge_network in spec	assets/templates/network_type.bkn.template	references/examples/k8s-network/network.bkn
Object	object_type	assets/templates/object_type.bkn.template	references/examples/k8s-network/object_types/pod.bkn
Relation	relation_type	assets/templates/relation_type.bkn.template	references/examples/k8s-network/relation_types/pod_belongs_node.bkn
Action	action_type	assets/templates/action_type.bkn.template	references/examples/k8s-network/action_types/restart_pod.bkn
Concept group	concept_group	assets/templates/concept_group.bkn.template	references/examples/k8s-network/concept_groups/k8s.bkn

Full rules and optional sections: references/SPECIFICATION.llm.md.

Naming conventions

• ID: lowercase, digits, underscores; file: {id}.bkn under the matching folder
• Headings: # network title, ## type block, ### section, #### logic property
• Frontmatter: at least type, id, name (see spec for each type)

Business rules placement

Rules must sit in spec-defined places so import persists them. Full wording: references/SPECIFICATION.llm.md.

• Network-level — prose in network.bkn right after # {title} (before structured sections like ## Network Overview)
• Type-level — prose in each type file after ## ObjectType: / ## RelationType: / … and before the first ###; never in frontmatter
• Property-level — in Data Properties table Description column
• No extra sections — do not add Markdown outside the standard sections; parsers may drop unparsed content on import

Validation checklist

• network.bkn at root; frontmatter matches spec
• Every .bkn has valid YAML frontmatter (type, id, name)
• Files live under folders matching type (object_types/, relation_types/, …); filename = {id}.bkn
• Network Overview lists all definition IDs — no missing/extra
• Relations/actions reference existing object-type IDs; concept groups list only existing objects
• Parameter binding Source ∈ property | input | const; YAML blocks (e.g. trigger) parse
• Heading hierarchy has no skipped levels
• Business rules only in allowed places (see Business rules placement)

Output rules

1. Emit raw .bkn content — do not wrap the whole file in a fenced markdown block
2. Reuse IDs consistently across relations/actions
3. IDs: lowercase + underscores; display text Chinese unless asked otherwise
4. Keep heading order per spec

Examples

• references/examples/k8s-network/ — modular sample (objects, relations, actions, concept group)

Delivered BKN: root SKILL.md

When you build a knowledge network directory {network_dir}/, add {network_dir}/SKILL.md at the root (alongside network.bkn). Short overview + index tables with file paths (object | path | relation | path | action | path) so agents route to the right .bkn without scanning. Optional: topology sketch, usage scenarios. Example: references/examples/k8s-network/SKILL.md.
