+# Agentic Resource Discovery (ARD)
+
+Git-Ape publishes an [ARD](https://agenticresourcediscovery.org) `ai-catalog.json` so that AI agents and tools that support Agentic Resource Discovery can automatically find and invoke Git-Ape skills.
+
+## What is ARD?
+
+Agentic Resource Discovery is an open protocol that lets AI agents discover skills and tools published by any team or organisation — similar to how DNS lets browsers discover websites. An AI agent can query an ARD catalog endpoint to find available skills, read their descriptions, and invoke them automatically.
+
+## Catalog Endpoint
+
+Git-Ape's catalog is published at:
+
+```
+https://azure.github.io/git-ape/.well-known/ai-catalog.json
+```
+
+The catalog lists all 15 Git-Ape skills.
+
+:::note
+Git-Ape's docs are a GitHub Pages **project** site, so the catalog is served under the `/git-ape/` path prefix (as shown above) rather than at the `azure.github.io` domain root. Register the full URL above with your ARD-enabled agent or discovery service.
+:::
+
+## Git-Ape Skills in the Catalog
+
+| Skill | Description |
+|---|---|
+| **Azure Cost Estimator** | Estimate monthly costs by querying the Azure Retail Prices API against ARM templates |
+| **Azure Deployment Preflight** | What-if analysis, permission checks, and resource change preview before any deployment |
+| **Azure Drift Detector** | Detect and reconcile configuration drift between deployed Azure resources and stored state |
+| **Azure Integration Tester** | Post-deployment health checks for Function Apps, Storage, Databases, and App Services |
+| **Azure Naming Research** | Look up CAF abbreviations, naming rules, and regex patterns for Azure resource types |
+| **Azure Policy Advisor** | Assess ARM templates for CIS/NIST/FedRAMP policy gaps and subscription-level assignments |
+| **Azure Resource Availability** | Validate VM SKUs, Kubernetes versions, API versions, and quota before deploying |
+| **Azure Resource Visualizer** | Generate Mermaid architecture diagrams from live Azure resource groups |
+| **Azure REST API Reference** | Look up exact property schemas, required fields, and stable API versions for any resource type |
+| **Azure Role Selector** | Recommend least-privilege RBAC roles for managed identities and service principals |
+| **Azure Security Analyzer** | Per-resource security assessment with severity ratings before deployment confirmation |
+| **Azure Stack Deploy** | Run a subscription-scoped Azure Deployment Stack and write `state.json` |
+| **Azure Stack Destroy** | Tear down a Git-Ape deployment and purge soft-deleted resources |
+| **Git-Ape Onboarding** | Bootstrap Entra OIDC, RBAC, GitHub environments, and CI/CD workflow scaffolding |
+| **Prerequisites Check** | Validate `az`, `gh`, `jq`, `git` installation and auth sessions |
+
+## Catalog Format
+
+The catalog follows the [ARD `ai-catalog.json` spec v1.0](https://agenticresourcediscovery.org):
+
+```json
+{
+  "specVersion": "1.0",
+  "host": { "displayName": "Azure Git-Ape", "identifier": "azure.github.io" },
+  "entries": [ ... ],
+  "collections": []
+}
+```
+
+Each `entries[]` item includes `identifier`, `displayName`, `type: "application/ai-skill"`, `url` (the skill's `SKILL.md`), and a `description` derived from the skill's `SKILL.md` frontmatter (condensed for length).
+
+The `collections[]` array is ARD's federation mechanism — it links sub-catalogs by URL so a crawler can resolve them without inlining their entries. Git-Ape's catalog currently federates no external collections, so it ships as `"collections": []`.
+
+## Adding Git-Ape to an ARD-Enabled Agent
+
+If your AI agent or tool supports ARD discovery, register the catalog URL:
+
+```
+https://azure.github.io/git-ape/.well-known/ai-catalog.json
+```
+
+The agent will discover all 15 Git-Ape skills and their descriptions, and can invoke them via the GitHub Copilot skill invocation protocol.
