+|---|---|---|
+| `gh issue list` | WIQL query via `az boards query` | `az boards query --wiql "SELECT ... FROM WorkItems WHERE ..."` |

+| Issue labels | Work Item tags | `az boards work-item update --fields "System.Tags=..."` |
+| `squad:{member}` label | `squad:{member}` tag on work items | Tags use `;` separator |
+
+**Prerequisites for Azure DevOps:**
+1. Run `az --version`. If missing: *"Azure DevOps mode requires the Azure CLI. Install from https://aka.ms/install-az-cli"*
+2. Run `az extension show --name azure-devops`. If missing: *"Run `az extension add --name azure-devops`"*
+3. Run `az account show`. If not logged in: *"Run `az login` to authenticate"*
+4. Verify defaults: `az devops configure --list` — org and project must be set

+# Squad Goes Enterprise — Azure DevOps, Area Paths, and Cross-Project Work Items
+
+> Blog post #23 — How Squad learned to work with enterprise ADO environments where nothing is "standard."
+
+## The Problem
+
+GitHub repos have issues. Simple. One repo, one issue tracker, one set of labels.
+
+Enterprise Azure DevOps? Not so much. Your code might live in one project, your work items in another. Your org might use "Scenario" instead of "User Story." Your team's backlog is scoped by area paths. Your sprints use iteration paths. And there's no PAT to manage — you authenticate via `az login`.
+
+Squad needed to understand all of this. Not just "detect ADO" — actually *work* in enterprise ADO environments where every project has its own rules.
+
+## What Shipped
+
+### Platform Auto-Detection
+
+Squad reads your git remote URL and figures out where you are:
+
+```
+https://dev.azure.com/myorg/myproject/_git/myrepo     → azure-devops
+git@ssh.dev.azure.com:v3/myorg/myproject/myrepo        → azure-devops
+https://myorg.visualstudio.com/myproject/_git/myrepo    → azure-devops
+```
+
+No configuration needed. `squad init` detects ADO and:
+- Skips `.github/workflows/` generation (those don't run in ADO)
+- Writes `"platform": "azure-devops"` to `.squad/config.json`
+- Generates ADO-appropriate MCP config examples
+
+### Configurable Work Item Types
+
+Not every ADO project uses "User Story." Some use "Scenario," "Bug," or custom types locked down by org policy. Now you can configure it:
+
+```json
+{
+  "version": 1,
+  "platform": "azure-devops",
+  "ado": {
+    "defaultWorkItemType": "Scenario"
+  }
+}
+```
+
+Squad uses your configured type for all work item creation — Ralph triage, agent task creation, everything.
+
+### Area Paths — Route to the Right Team
+
+In enterprise ADO, area paths determine which team's backlog a work item appears in. A work item in `"MyProject\Frontend"` shows up on the Frontend team's board. One in `"MyProject\Platform"` goes to Platform.
+
+```json
+{
+  "ado": {
+    "areaPath": "MyProject\\Team Alpha"
+  }
+}
+```
+
+Now when Squad creates work items, they land on the right team's board — not lost in the root backlog.
+
+### Iteration Paths — Sprint Placement
+
+Same story for sprints. Enterprise teams plan in iterations, and work items need to appear in the right sprint:
+
+```json
+{
+  "ado": {
+    "iterationPath": "MyProject\\Sprint 5"
+  }
+}
+```
+
+### Cross-Project Work Items — The Enterprise Killer Feature
+
+Here's the one that matters most for large organizations: **your git repo and your work items might live in completely different ADO projects — or even different orgs.**
+
+Common pattern in enterprise:
+- **Code** lives in `Engineering/my-service` (locked-down project with strict CI)
+- **Work items** live in `Planning/team-backlog` (PM-managed project with custom process templates)
+
+Squad now supports this cleanly:
+
+```json
+{
+  "version": 1,
+  "platform": "azure-devops",
+  "ado": {
+    "org": "planning-org",
+    "project": "team-backlog",
+    "defaultWorkItemType": "Scenario",
+    "areaPath": "team-backlog\\Alpha Squad",
+    "iterationPath": "team-backlog\\2026-Q1\\Sprint 5"
+  }
+}
+```
+
+When `ado.org` or `ado.project` are set, Squad uses them for all work item operations (create, query, tag, comment) while continuing to use the git remote's org/project for repo operations (branches, PRs, commits).
+
+The WIQL queries, `az boards` commands, and Ralph's triage loop all respect this split.
+
+## The Full Config Reference
+
+All fields are optional. Omit any field to use the default.
+
+| Field | Default | Description |
+|-------|---------|-------------|
+| `ado.org` | *(from git remote)* | ADO org for work items |
+| `ado.project` | *(from git remote)* | ADO project for work items |
+| `ado.defaultWorkItemType` | `"User Story"` | Type for new work items |
+| `ado.areaPath` | *(project default)* | Team backlog routing |
+| `ado.iterationPath` | *(project default)* | Sprint board placement |
+
+## Security — No PATs Needed
+
+Squad uses `az login` for authentication. No Personal Access Tokens to rotate, no secrets in config files. Your Azure CLI session handles everything.
+
+For environments where MCP tools are available, Squad also supports the Azure DevOps MCP server for richer API access:
+
+```json
+{
+  "mcpServers": {
+    "azure-devops": {
+      "command": "npx",
+      "args": ["-y", "@azure/devops-mcp-server"]
+    }
+  }
+}
+```
+
+## Security Hardening
+
+The ADO adapter went through a thorough security review:
+
+- **Shell injection prevention** — All `execSync` calls replaced with `execFileSync` (args as arrays, not concatenated strings)
+- **WIQL injection prevention** — `escapeWiql()` helper doubles single-quotes in all user-supplied values
+- **Bearer token protection** — Planner adapter passes tokens via `curl --config stdin` instead of CLI args (invisible to `ps aux`)
+
+## What We Tested
+
+External integration testing against real ADO environments (WDATP, OS, SquadDemo projects):
+
+| Test | Result |
+|------|--------|
+| ADO project connectivity | ✅ |
+| Repo discovery | ✅ |
+| Branch creation | ✅ |
+| Git clone + push | ✅ |
+| Squad init (platform detection) | ✅ |
+| PR creation + auto-complete | ✅ |
+| PR read/list/comment | ✅ |
+| Commit search | ✅ |
+| Work item CRUD | ✅ |
+| WIQL tag queries | ✅ |
+| Cross-project work items | ✅ |
+
+The only blockers encountered were project-specific restrictions (locked-down work item types in WDATP) — not Squad bugs.
+
+## Ralph in ADO
+
+Ralph's coordinator prompt is now platform-aware. When running against ADO, Ralph uses WIQL queries instead of GitHub issue queries:
+
+```wiql
+SELECT [System.Id] FROM WorkItems 
+WHERE [System.Tags] Contains 'squad' 
+  AND [System.State] <> 'Closed'
+  AND [System.TeamProject] = 'team-backlog'
+ORDER BY [System.CreatedDate] DESC
+```
+
+The full triage → assign → branch → PR → merge loop works end-to-end with ADO.
+
+## Ralph + ADO: The Governance Fix
+
+The coordinator prompt (`squad.agent.md`) is what tells Ralph *where* to look for work. Previously, it only had GitHub commands — `gh issue list`, `gh pr list`. Even if the ADO adapter was perfect, Ralph would still scan GitHub because that's what the governance file told it to do.
+
+We fixed this at every level:
+- **MCP detection** — Added `azure-devops-*` to the tool prefix table so the coordinator recognizes ADO MCP tools
+- **Platform Detection section** — New section in the governance file explaining how to detect GitHub vs ADO from the git remote
+- **Issue Awareness** — Now shows both GitHub and ADO queries, with instructions to read `.squad/config.json` first
+- **Ralph Step 1** — Platform-aware scan with both GitHub and ADO command blocks, plus the critical instruction: *"Read `.squad/config.json` for the `ado` section FIRST — do NOT guess the ADO project from the repo name"*
+
+This is the kind of bug that's invisible in unit tests — the code works, but the governance prompt doesn't tell the coordinator to use it.
+
+## Getting Started
+
+```bash
+# 1. Install Squad
+npm install -g @bradygaster/squad-cli
+
+# 2. Clone your ADO repo
+git clone https://dev.azure.com/your-org/your-project/_git/your-repo
+cd your-repo
+
+# 3. Make sure az CLI is set up
+az login
+az extension add --name azure-devops
+
+# 4. Init Squad (auto-detects ADO)
+squad init
+
+# 5. Edit .squad/config.json if you need custom work item config
+# 6. Start working!
+```
+
+Full documentation: [Enterprise Platforms Guide](../features/enterprise-platforms.md)
+
+## What's Next
+
+- **Process template introspection** — Auto-detect available work item types from the ADO process template (#240)
+- **ADO webhook integration** — Real-time work item change notifications
+- **Azure Pipelines scaffolding** — Generate pipeline YAML during `squad init` for ADO repos

+# Enterprise Platforms
+
+Squad supports Azure DevOps and Microsoft Planner in addition to GitHub. When your git remote points to Azure DevOps, Squad automatically detects the platform and adapts its commands. For work-item tracking, Squad also supports a hybrid model where code lives in one platform and tasks live in Microsoft Planner.
+
+## Prerequisites
+
+1. **Azure CLI** — Install from [https://aka.ms/install-az-cli](https://aka.ms/install-az-cli)
+2. **Azure DevOps extension** — `az extension add --name azure-devops`
+3. **Login** — `az login`
+4. **Set defaults** — `az devops configure --defaults organization=https://dev.azure.com/YOUR_ORG project=YOUR_PROJECT`
+
+Verify setup:
+
+```bash
+az devops configure --list
+# Should show organization and project
+```
+
+## How It Works
+
+Squad auto-detects the platform from your git remote URL:
+
+| Remote URL pattern | Detected platform |
+|---|---|
+| `github.com` | GitHub |
+| `dev.azure.com` | Azure DevOps |
+| `*.visualstudio.com` | Azure DevOps |
+| `ssh.dev.azure.com` | Azure DevOps |
+
+## Differences from GitHub
+
+### Work Items vs Issues
+
+| GitHub | Azure DevOps |
+|---|---|
+| Issues | Work Items |
+| Labels (e.g., `squad:alice`) | Tags (e.g., `squad:alice`) |
+| `gh issue list --label X` | WIQL query via `az boards query` |
+| `gh issue edit --add-label` | `az boards work-item update --fields "System.Tags=..."` |
+
+### Pull Requests
+
+| GitHub | Azure DevOps |
+|---|---|
+| `gh pr list` | `az repos pr list` |
+| `gh pr create` | `az repos pr create` |
+| `gh pr merge` | `az repos pr update --status completed` |
+| Review: Approved / Changes Requested | Vote: 10 (approved) / -10 (rejected) |
+
+### Branch Operations
+
+Branch operations use the same `git` commands on both platforms. Squad creates branches with the naming convention `squad/{id}-{slug}`.
+
+## Ralph on Azure DevOps
+
+Ralph works identically on ADO — he scans for untriaged work items using WIQL queries instead of GitHub label filters:
+
+```
+# GitHub
+gh issue list --label "squad:untriaged" --json number,title,labels
+
+# Azure DevOps
+az boards query --wiql "SELECT [System.Id],[System.Title],[System.Tags] FROM WorkItems WHERE [System.Tags] Contains 'squad:untriaged'"
+```
+
+Tag assignment uses the same `squad:{member}` convention, stored as ADO work item tags separated by `;`.
+
+## Configuration
+
+Squad auto-detects ADO from the git remote URL. For basic use, no extra configuration is needed.
+
+### Work Item Configuration
+
+When your ADO environment has custom work item types, area paths, iterations, or when work items live in a **different project or org** than the git repo, configure the `ado` section in `.squad/config.json`:
+
+```json
+{
+  "version": 1,
+  "teamRoot": "/path/to/repo",
+  "platform": "azure-devops",
+  "ado": {
+    "org": "my-org",
+    "project": "my-work-items-project",
+    "defaultWorkItemType": "Scenario",
+    "areaPath": "MyProject\\Team Alpha",
+    "iterationPath": "MyProject\\Sprint 5"
+  }
+}
+```
+
+| Field | Default | Description |
+|-------|---------|-------------|
+| `ado.org` | *(from git remote)* | ADO org for work items — set when work items are in a different org than the repo |
+| `ado.project` | *(from git remote)* | ADO project for work items — set when work items are in a different project |
+| `ado.defaultWorkItemType` | `"User Story"` | Default type for new work items. Some orgs use `"Scenario"`, `"Bug"`, or custom types |
+| `ado.areaPath` | *(project default)* | Area path for new work items — controls which team's backlog they appear in |
+| `ado.iterationPath` | *(project default)* | Iteration/sprint path — controls which sprint board work items appear on |
+
+All fields are optional. Omitted fields use the defaults shown above.
+
+### Authentication
+
+Squad uses the Azure CLI for ADO authentication — **no Personal Access Tokens (PATs) needed.** Run `az login` once, and Squad agents use your authenticated session for all operations.
+
+Alternatively, if the Azure DevOps MCP server is configured in your environment, Squad will use it automatically for richer API access. Add it to `.copilot/mcp-config.json`:
+
+```json
+{
+  "mcpServers": {
+    "azure-devops": {
+      "command": "npx",
+      "args": ["-y", "@azure/devops-mcp-server"]
+    }
+  }
+}
+```
+
+Squad prefers MCP tools when available, falling back to `az` CLI when not.
+
+To explicitly check which platform Squad detects:
+
+```typescript
+import { detectPlatform } from '@bradygaster/squad/platform';
+
+const platform = detectPlatform('/path/to/repo');
+// Returns 'github', 'azure-devops', or 'planner'
+```
+
+---
+
+## Microsoft Planner Support (Hybrid Model)
+
+Squad supports a hybrid model where your **repository** lives in GitHub or Azure DevOps, but **work items** are tracked in Microsoft Planner. This is common in enterprise environments where project management uses Planner while engineering uses ADO or GitHub for code.
+
+### How It Works
+
+- Planner **buckets** map to squad assignments: `squad:untriaged`, `squad:riker`, `squad:data`, etc.
+- Moving a task between buckets = reassigning to a team member
+- Task completion = 100% complete or move to "Done" bucket
+- PRs and branches still go through the repo adapter (GitHub or Azure DevOps)
+
+### Prerequisites
+
+1. **Azure CLI** — `az login`
+2. **Graph API access** — `az account get-access-token --resource-type ms-graph`
+3. **Plan ID** — Found in the Planner URL or via Graph API
+
+### Configuration
+
+In `squad.config.ts`, specify the hybrid model:
+
+```typescript
+const config: SquadConfig = {
+  // ... other config
+  platform: {
+    repo: 'azure-devops',     // where code lives
+    workItems: 'planner',     // where tasks live
+    planId: 'rYe_WFgqUUqnSTZfpMdKcZUAER1P',
+  },
+};
+```
+
+### Ralph with Planner
+
+Ralph scans Planner tasks via the Microsoft Graph API instead of GitHub labels or ADO WIQL:
+
+```
+# List untriaged tasks
+GET /planner/plans/{planId}/tasks  →  filter by "squad:untriaged" bucket
+
+# Assign to member (move to their bucket)
+PATCH /planner/tasks/{taskId}  →  { "bucketId": "{squad:member bucket ID}" }
+```
+
+PR operations still use the repo adapter:
+
+```
+# Repo on Azure DevOps
+az repos pr list --status active
+az repos pr create --source-branch ... --target-branch ...
+
+# Repo on GitHub
+gh pr list --state open
+gh pr create --head ... --base ...

+# Platform Adapter — Design Spec
+
+## Overview
+
+The Platform Adapter abstraction allows Squad to work with multiple source code hosting platforms (GitHub, Azure DevOps) through a unified interface. This enables Ralph and the coordinator to use the same triage/assignment logic regardless of the underlying platform.
+
+## Design Decisions
+
+### 1. Interface-based abstraction
+
+We use a TypeScript interface (`PlatformAdapter`) rather than an abstract class. This keeps the contract pure and allows each adapter to manage its own dependencies independently.
+
+### 2. CLI-based implementations
+
+Both adapters wrap CLI tools (`gh` for GitHub, `az` for ADO) rather than using REST APIs directly. This:
+- Leverages existing authentication (users are already logged into `gh`/`az`)
+- Avoids managing OAuth tokens, PATs, or refresh flows
+- Matches how Squad already interacts with GitHub
+
+### 3. Auto-detection from git remote
+
+Platform detection reads the `origin` remote URL. This is zero-config — users don't need to specify which platform they're on.
+
+### 4. Graceful failure
+
+If the required CLI is not installed, the adapter throws a descriptive error with installation instructions rather than a cryptic exec failure.
+
+## Mapping Table
+

+## Platform Detection
+
+On session start, detect the platform from git remote:
+- `github.com` → Use GitHub commands (`gh` CLI)
+- `dev.azure.com` or `*.visualstudio.com` → Use Azure DevOps commands (`az` CLI)
+
+If `squad.config.ts` specifies `workItems: 'planner'`, use Microsoft Planner for work items regardless of where the repo lives.
+
+### Azure DevOps Mode
+
+If the git remote points to Azure DevOps:
+
+| GitHub concept | Azure DevOps equivalent | Command change |
+|---|---|---|
+| `gh issue list` | WIQL query via `az boards query` | `az boards query --wiql "SELECT ... FROM WorkItems WHERE ..."` |
+| `gh pr list` | `az repos pr list` | `az repos pr list --status active` |
+| `gh pr create` | `az repos pr create` | `az repos pr create --source-branch ... --target-branch ...` |
+| `gh pr merge` | `az repos pr update --status completed` | Set PR status to completed |
+| Issue labels | Work Item tags | `az boards work-item update --fields "System.Tags=..."` |
+| `squad:{member}` label | `squad:{member}` tag on work items | Tags use `;` separator |
+
+**Prerequisites for Azure DevOps:**
+1. Run `az --version`. If missing: *"Azure DevOps mode requires the Azure CLI. Install from https://aka.ms/install-az-cli"*
+2. Run `az extension show --name azure-devops`. If missing: *"Run `az extension add --name azure-devops`"*
+3. Run `az account show`. If not logged in: *"Run `az login` to authenticate"*
+4. Verify defaults: `az devops configure --list` — org and project must be set
+
+**Ralph on Azure DevOps:**
+- **Read `.squad/config.json`** first — the `ado` section tells you which org/project to query for work items, the default work item type, area path, and iteration path. If `ado.org`/`ado.project` are set, use those (they may differ from the repo's org/project). If not set, fall back to org/project parsed from `git remote get-url origin`.
+- Replace `gh issue list --label "squad:untriaged"` with WIQL: `az boards query --wiql "SELECT ... WHERE [System.Tags] Contains 'squad:untriaged' AND [System.TeamProject] = '{project}'" --org "https://dev.azure.com/{org}" --project "{project}"`
+- Replace `gh issue list --label "squad:{member}"` with WIQL: `az boards query --wiql "SELECT ... WHERE [System.Tags] Contains 'squad:{member}'" --org ... --project ...`
+- Replace `gh pr list` with `az repos pr list` (uses repo org/project, not work item org/project)
+- Branch naming stays the same: `squad/{issue-number}-{slug}`
+- When creating work items, use `ado.defaultWorkItemType` (default: "User Story"), include `ado.areaPath` and `ado.iterationPath` if configured
+
+### Microsoft Planner Mode (Hybrid)
+
+If work items are in Microsoft Planner (configured via `squad.config.ts` with `workItems: 'planner'`):
+- Ralph scans Planner tasks via Microsoft Graph API
+- Buckets map to squad member assignments (squad:riker, squad:data, etc.)
+- The "squad:untriaged" bucket = triage inbox
+- Moving a task between buckets = assigning to a team member
+- Task completion = move to "Done" bucket
+- PRs and branches still use the repo adapter (GitHub or Azure DevOps)
+
+**Prerequisites for Planner:**
+1. Run `az login` to authenticate
+2. Ensure `az account get-access-token --resource-type ms-graph` succeeds
+3. Set `workItems: 'planner'` and `planId` in `squad.config.ts`
+
+**Ralph on Planner:**
+- Scan untriaged: Graph API `GET /planner/plans/{planId}/tasks` filtered by `squad:untriaged` bucket
+- Assign to member: `PATCH /planner/tasks/{taskId}` → move to `squad:{member}` bucket
+- PRs: Use the repo adapter commands (GitHub or Azure DevOps)
