Spec Kit Integration Catalog

The integration catalog enables discovery, versioning, and distribution of AI agent integrations for Spec Kit.

Catalog Files

Built-In Catalog (catalog.json)

Contains integrations that ship with Spec Kit. These are maintained by the core team and always installable.

Community Catalog (catalog.community.json)

Community-contributed integrations. Listed for discovery only — users install from the source repositories.

Catalog Configuration

The catalog stack is resolved in this order (first match wins):

1. Environment variable — SPECKIT_INTEGRATION_CATALOG_URL overrides all catalogs with a single URL
2. Project config — .specify/integration-catalogs.yml in the project root
3. User config — ~/.specify/integration-catalogs.yml in the user home directory
4. Built-in defaults — catalog.json + catalog.community.json

Example integration-catalogs.yml:

catalogs:
  - url: "https://example.com/my-catalog.json"
    name: "my-catalog"
    priority: 1
    install_allowed: true

CLI Commands

# List built-in integrations (default)
specify integration list

# Browse full catalog (built-in + community)
specify integration list --catalog

# Install an integration
specify integration install copilot

# Upgrade the current integration (diff-aware)
specify integration upgrade

# Upgrade with force (overwrite modified files)
specify integration upgrade --force

Integration Descriptor (integration.yml)

Each integration can include an integration.yml descriptor that documents its metadata, requirements, and provided commands/scripts:

schema_version: "1.0"
integration:
  id: "my-agent"
  name: "My Agent"
  version: "1.0.0"
