Constitution Spec Support

Organizational governance with inheritance hierarchy:

# constitutions/org/acme.yaml
apiVersion: visionspec/v1
kind: Constitution
metadata:
  name: acme
  level: organization

technical:
  languages:
    backend:
      primary: go
      allowed: [go, rust]
  tenancy:
    model: multi-tenant
    isolation: rls

infrastructure:
  iac:
    tool: pulumi
    language: go

Constitutions flow down through inheritance:

org/acme.yaml           # Organization defaults
    ↓ inherits
team/platform.yaml      # Team overrides
    ↓ inherits
project/api.yaml        # Project-specific

Claude Code Skills

New skills for AI assistant integration:

# Available skills
/visionspec-eval       # Evaluate specifications
/visionspec-export     # Export to targets
/visionspec-lint       # Validate structure
/visionspec-reconcile  # Generate spec.md
/visionspec-status     # Check readiness
/visionspec-synthesize # Generate specs

Agent Specs

Pre-configured agent specifications for:

  • Orchestrator - Coordinates spec workflow
  • Evaluator - Runs rubric-based evaluation
  • Synthesizer - Generates derived specs
  • Exporter - Exports to target systems
  • Reconciler - Resolves conflicts

MCP Resource Handlers

Programmatic access to spec content via MCP:

# Start MCP server
visionspec serve

# Resources exposed:
# - projects/{project}/specs/{type}
# - projects/{project}/status
# - projects/{project}/eval/{type}
