06 — ARIA CLI

Discover, audit, and install ARIA-governed AI assets into your development runtimes using the ARIA Package Manager.

What you’ll do

Initialize the aria CLI with your consumer identity and registry
Search for assets by OASF skill taxonomy
Inspect an asset’s OASF Record and governance overlay
Audit governance compliance before installing
Install an MCP skill into Claude Desktop
See governance blocking an over-classified install

Step 1: Build the CLI

cd src/aria-cli
dotnet build

Run it to see the command tree:

dotnet run -- --help

Output:

Description:
  aria — ARIA Package Manager for OASF-governed AI assets

Usage:
  aria [command] [options]

Commands:
  init       Initialize aria configuration in ~/.aria/config.json
  search     Discover AI assets by OASF skill, domain, or keyword
  inspect    Display OASF Record and governance overlay for an asset
  audit      Validate governance compliance before install
  install    Pull and install an AI asset into a target runtime
  list       List installed AI assets

Step 2: Initialize configuration

dotnet run -- init

This creates ~/.aria/config.json with default values. Edit it to match your environment:

cat ~/.aria/config.json | jq .

The key fields:

{
  "consumer_id": "my-team",
  "sensitivity_ceiling": "confidential",
  "registries": ["ghcr.io/my-org/aria-assets"],
  "targets": {
    "claude-desktop": {
      "config_path": "~/Library/Application Support/Claude/claude_desktop_config.json"
    },
    "agent-framework": {
      "project_path": "./src",
      "a2a_endpoint": "https://agents.myorg.com"
    },
    "vscode": {
      "workspace_path": "./.vscode/mcp.json"
    }
  }
}

The consumer_id identifies your team for allow-list checks. The sensitivity_ceiling sets the maximum classification you’re authorized to install.

Step 3: Search for assets

# Search by skill taxonomy
dotnet run -- search --skill "knowledge_retrieval/rag"

# Search by domain
dotnet run -- search --domain "human_resources"

# Combine filters
dotnet run -- search --skill "rag" --domain "human_resources"

You’ll see a table of matching assets:

┌──────────────────────────────────────────┬─────────┬───────────────┬──────┬──────────────────────────┐
│ Name                                     │ Version │ Type          │ Skills│ Description             │
├──────────────────────────────────────────┼─────────┼───────────────┼──────┼──────────────────────────┤
│ aria.dev/agents/onboarding-assistant    │ 2.1.0   │ agent         │ rag  │ HR onboarding agent...  │
│ aria.dev/skills/policy-lookup           │ 1.0.0   │ mcp_server    │ rag  │ MCP server for HR...    │
│ aria.dev/knowledge/hr-policies          │ 3.0.0   │ knowledge_base│ rag  │ HR policy knowledge...  │
└──────────────────────────────────────────┴─────────┴───────────────┴──────┴──────────────────────────┘

Step 4: Inspect an asset

Before installing, inspect the full OASF metadata:

dotnet run -- inspect ghcr.io/jgarverick/aria-assets/onboarding-assistant:2.1.0

This displays two panels:

OASF Record — name, version, skills, domains, modules, authors
Governance Overlay — sensitivity tier, classifications, ceiling, approval chain, allowed consumers, compliance frameworks

This is the governance-aware equivalent of npm info or docker inspect.

Step 5: Audit governance

Check whether you’re authorized to install an asset:

# This should PASS (confidential ≤ confidential)
dotnet run -- audit ghcr.io/jgarverick/aria-assets/onboarding-assistant:2.1.0 \
  --ceiling confidential

Output:

✓ All governance checks passed
  Asset tier: confidential
  Your ceiling: confidential
  Consumer: my-team
  Frameworks: SOC2, GDPR

Now try with a ceiling that’s too low:

# This should FAIL (confidential > public)
dotnet run -- audit ghcr.io/jgarverick/aria-assets/onboarding-assistant:2.1.0 \
  --ceiling public

Output:

✗ Asset sensitivity 'confidential' exceeds your ceiling 'public'.
  Request elevated access from the AI Governance team.
  Required approvals: ai-governance → hr-data-steward

The CLI shows exactly what approvals you’d need to get access.

Step 6: Install to a target

Install an MCP skill into Claude Desktop:

dotnet run -- install ghcr.io/jgarverick/aria-assets/policy-lookup-skill:1.0.0 \
  --target claude-desktop

The install flow:

aria install ghcr.io/jgarverick/aria-assets/policy-lookup-skill:1.0.0 → claude-desktop

1. Fetching OASF metadata...
   Asset: aria.dev/skills/policy-lookup v1.0.0
2. Validating governance...
   ✓ Sensitivity: internal ≤ confidential
   ✓ Consumer 'my-team' is authorized
3. Pulling OCI artifact...
   Cached to: ~/.aria/cache/aria.dev-skills-policy-lookup
4. Installing to claude-desktop...
   Registering MCP server 'policy-lookup' in Claude Desktop
     Transport: stdio
     Tools: lookup_policy, list_policies
   Config: ~/Library/Application Support/Claude/claude_desktop_config.json

✓ Successfully installed aria.dev/skills/policy-lookup v1.0.0 → claude-desktop

For Agent Framework:

dotnet run -- install ghcr.io/jgarverick/aria-assets/onboarding-assistant:2.1.0 \
  --target agent-framework

This registers the agent as a remote A2A endpoint instead of modifying a Claude Desktop config file.

Step 7: List installed assets

dotnet run -- list

Shows all installed assets with their governance metadata:

┌─────────────────────────────────┬─────────┬────────────┬─────────────────┬──────────────┬────────────┐
│ Name                            │ Version │ Type       │ Target          │ Sensitivity  │ Installed  │
├─────────────────────────────────┼─────────┼────────────┼─────────────────┼──────────────┼────────────┤
│ aria.dev/skills/policy-lookup  │ 1.0.0   │ mcp_server │ claude-desktop  │ internal     │ 2026-05-01 │
└─────────────────────────────────┴─────────┴────────────┴─────────────────┴──────────────┴────────────┘

How the install targets work

The CLI uses pluggable adapters for different runtimes:

Target	What it does
claude-desktop	Reads the OASF module descriptor, generates a `claude_desktop_config.json` entry with command, args, and transport, then writes it to the Claude Desktop config path
vscode	Similar to Claude Desktop but targets `.vscode/mcp.json` in the workspace
agent-framework	For MCP modules, registers as a tool provider. For agent Records, registers as a remote A2A endpoint using the `a2a_endpoint` from config

Adding a new target is straightforward — implement IInstallTarget with a Name and InstallAsync method, then register it in TargetRegistry.

GitHub CLI extension

For teams standardized on gh, the same commands are available as:

gh extension install jgarverick/gh-aria
gh aria search --skill "knowledge_retrieval/rag"
gh aria install jgarverick/aria-policy-lookup-skill --target claude-desktop
gh aria audit --pr 42 --ceiling confidential

The --pr flag on audit is particularly useful during code review — it validates the governance overlay in a pull request before approval.
