Skill: x-create-capability
Purpose
Decompose a Product artifact into Capability artifacts with explicit RNF inheritance from the parent product. Each capability carries a ## Inherited RNFs section with no-relax markers for non-negotiable constraints. Optionally generates a C2 stub (second capability) as a starting point for further decomposition.
Position in hierarchy: Ideation → Product → Capability → Feature → Epic → Story → Task.
When to Use
- After
x-create-productproduces aai/products/product-NNNN.md - When decomposing a product into its capability areas (3–7 capabilities recommended)
- Before
x-create-feature
CLI Command
ia-dev-env x-create-capability --capability-id capability-c1 --capabilities '[{"name":"Auth","description":"..."}]'
ia-dev-env x-create-capability --capability-id capability-c1 --auto-decompose
Triggers
/x-create-capability --capability-id <ID> --capabilities '<JSON>'/x-create-capability --capability-id <ID> --auto-decompose
Arguments
| Flag | Required | Description |
| :--- | :--- | :--- |
| --capability-id | yes | Capability identifier (e.g. capability-c1) |
| --capabilities | cond. | JSON array [{"name":"...","description":"..."},...] (4–8 entries) |
| --auto-decompose | cond. | Auto-decompose product into capabilities using heuristic |
| --output-dir | no | Output directory (default: ai/capabilities/) |
Either --capabilities or --auto-decompose is required.
Output
Produces:
ai/capabilities/capability-NNNN.md— Capability artifact with 7 sections + Inherited RNFs + no-relax markers- Console summary with capability-id and inherited RNF count
Exit Codes
| Code | Meaning | | :--- | :--- | | 0 | Success | | 1 | Validation error | | 2 | Execution error |
Examples
# Explicit capabilities
ia-dev-env x-create-capability --capability-id capability-c1 \
--capabilities '[{"name":"Authentication","description":"User auth flows"}]'
# Auto-decompose
ia-dev-env x-create-capability --capability-id capability-c1 --auto-decompose
