Host profile

The host profile is a single document describing what a device is, what it can do, and what policy governs agent registration.

Location

Scope	Path
Personal	`~/.asmp/host.yaml`
System	`/etc/asmp/host.yaml`

Schema (v0.1)

asmp: "0.1"
kind: host

# Identity

Fields

Identity

Field	Type	Required	Description
`asmp`	string	yes	Protocol version (`"0.1"`)
`kind`	string	yes	Always `host`
`host_id`	string	yes	Stable device identifier
`device_class`	enum	yes	`personal_computer`, `server`, `homelab`, `vm`

OS and hardware

Informational. Helps agents make decisions about resource-intensive tasks.

Capabilities

Host-level capabilities (not service-level). Declares what classes of work this device supports.

Registry

Field	Description
`path`	Directory containing `*.asmp.yaml` manifests
`api`	Registration protocol HTTP endpoint

Policy

Field	Description
`agent_can_register`	Whether agents may POST new services
`requires_approval`	Queue registrations for human review
`max_services`	Maximum registered services
`allowed_ports`	Port range agents may claim (string range or list)
`data_sensitivity_default`	Default sensitivity for new services

Discovery

Controls how the registry finds shipped asmp.yaml files:

discovery:
  scan_paths:
    - ~/repos-personal
    - ~/repos-aic
    - ~/repos-eidos-agi
  scan_interval: 5m
  stale_after: 900

Field	Default	Description
`scan_paths`	`~/repos-personal`, `~/repos-aic`, `~/repos-eidos-agi`	Roots to walk for `/asmp.yaml` and `/infra/asmp.yaml`
`scan_interval`	`5m`	Background scan period
`stale_after`	`900`	Seconds before a scan-synced service is marked stale

Observability

Paths and endpoints for logs and metrics. Consumers use these for health dashboards.
