Setup Enterprise Stack

Setup Enterprise Stack

Emit the paste-ready enabledPlugins + extraKnownMarketplaces block for the four public Microsoft ecosystem plugins any Microsoft-subscribed tenant can use, and optionally install them after explicit user consent. Defaults to repo scope — these are project-specific tools.

When to fire

• The user asks to enable the Microsoft ecosystem — "set up Azure + Fabric + Power BI + M365 for Copilot"
• The user invokes /alex-act-one setup-enterprise
• The user asks what block goes into ~/.copilot/settings.json for the public Microsoft plugins
• Auditing or repairing a workspace where some of them are missing, disabled, or stale

The plugins

copilot-plugins is the built-in Copilot marketplace and does not need explicit registration. azure-skills and fabric-collection are additional marketplaces the user must register in extraKnownMarketplaces before enabling their plugins.

Verify names before emitting, under the right account

copilot plugin marketplace browse returns different results depending on which GitHub account is active. A corporate account sees internal marketplace entries that a personal account does not, so the same command can report a plugin as absent purely because of who is signed in.

Check gh auth status first. If the user has more than one account, verify against the one whose tenant the plugins belong to. A "not found" under the wrong account is not evidence the plugin was retired, and acting on it would remove a working entry.

Prerequisites

Before running any install command, verify the user has:

• Copilot CLI: copilot --version >= 1.0.75. If missing, direct the user to https://github.com/github/copilot-cli for installation.
• Azure subscription: required to actually invoke azure@azure-skills skills against real resources. The plugin registers without a subscription, but skill invocations against az will fail without one.
• Fabric workspace: required for fabric-skills to reach a live capacity. Registration and skill loading do not require a workspace.
• Power BI license: powerbi-authoring@fabric-collection requires either a Power BI Pro or Premium Per User license for authoring against real workspaces.
• Microsoft 365 tenant: required for microsoft-365-agents-toolkit@copilot-plugins when publishing agents; not required for local scaffolding.

Missing prerequisites do not block registration; they surface at first skill invocation. Warn the user but do not refuse to emit the block.

Emit block

Produce this block as an emitable, paste-ready JSON snippet. Do not modify the user's ~/.copilot/settings.json without explicit consent (see Install flow below).

Emit-only safety boundary

When the user selects emit only, or does not select a mode and receives the safe default, do not create or update todos, tasks, plan items, or any other host planning state. Do not modify files, settings, plugins, or marketplace registrations. Return the block and guidance directly.

{
  "extraKnownMarketplaces": {
    "azure-skills": {
      "source": { "source": "github", "repo": "microsoft/azure-skills" }
    },
    "fabric-collection": {
      "source": { "source": "github", "repo": "microsoft/skills-for-fabric" }
    }
  },
  "enabledPlugins": {
    "azure@azure-skills": true,
    "fabric-skills@copilot-plugins": true,
    "powerbi-authoring@fabric-collection": true,
    "microsoft-365-agents-toolkit@copilot-plugins": true
  }
}

The block enables all four. Edit the local enabledPlugins after pasting to drop plugins they do not need — for example, a user on Azure only can remove the Fabric, Power BI, and M365 entries.

Scope decision (do this first)

Before any of the three modes below, decide the target scope:

Default is repo scope. These are project-specific tools (Azure = Azure projects; Fabric = Fabric projects; etc.); loading them at user scope means every non-Microsoft workspace pays the context cost for skills the user will never invoke there.

The rule: "Am I this? → user scope. Am I working on this? → repo scope." These target plugins answer the second question, not the first.

Ask the user which scope, or accept an explicit --user flag. Default to repo when unspecified.

Install flow

Three modes. Ask the user which they want; default to (1). Every mode uses the scope decided above.

1. Emit only (default, safe)

Print the JSON block above with instructions targeted at the chosen scope:

Repo scope (default): Paste this block into .github/copilot/settings.json in the current workspace. Create the file if it does not exist. If the file already has extraKnownMarketplaces or enabledPlugins keys, merge — do not overwrite existing entries. Commit the file (it belongs in source control; teammates will inherit the setup on clone). Then run the individual copilot plugin install <name>@<marketplace> commands shown in consent-gated auto-install mode.

User scope (--user opt-in): Paste this block into ~/.copilot/settings.json on this machine. If the file already has keys, merge. The block will apply to every workspace you open on this machine.

No filesystem write. No CLI invocation. user owns the paste + install.

2. Consent-gated auto-install

Only after explicit "yes, install them" from the user. Merge the block into the target file per the chosen scope:

# Repo scope (default): merge into <workspace>/.github/copilot/settings.json
# User scope (--user):  merge into ~/.copilot/settings.json
# then run the marketplace + install commands:
copilot plugin marketplace add microsoft/azure-skills
copilot plugin marketplace add microsoft/skills-for-fabric
copilot plugin install azure@azure-skills
copilot plugin install fabric-skills@copilot-plugins
copilot plugin install powerbi-authoring@fabric-collection
copilot plugin install microsoft-365-agents-toolkit@copilot-plugins

Additive settings merge: if the target file already has an enabledPlugins map with unrelated entries, preserve them. If it already has entries for one of them, warn but do not overwrite unless the user also asked to reset.

Marketplaces register at user scope regardless of the enabledPlugins scope choice. The marketplace add commands write to ~/.copilot/settings.json extraKnownMarketplaces — that is where the CLI reads marketplace registration from. Only the enabledPlugins map moves between user and repo scope in this skill.

3. Audit only

Read the current settings file at the chosen scope. Under --user, read ~/.copilot/settings.json; otherwise read .github/copilot/settings.json in the workspace. Compare against the target block, produce a table:

The "other scope" column surfaces Users who accidentally enabled at user scope when repo scope was intended (or vice versa). Do not modify anything. Report only. user decides what to do with the audit.

Safety rules

• Never overwrite a settings file (repo OR user) without explicit consent from the user.
• Never disable a plugin the user did not ask to disable — merge, don't replace.
• Never install plugins from marketplaces outside the two named (microsoft/azure-skills, microsoft/skills-for-fabric). Any expansion needs a separate proposal.
• Never silently pick user scope. Default is repo. Only switch to user on explicit --user request from the user.
• Do warn if the user already has enabledPlugins entries at either scope that conflict with these (for example, a pre-existing fabric-skills@my-fork at repo scope with the target fabric-skills@copilot-plugins at user scope would produce a plugin-name collision the CLI resolves via last-write-wins).
• Do verify the CLI version before offering install mode; refuse to proceed if the CLI is too old (missing the marketplace-add subcommand).
• Do remind the user that the repo file gets committed — teammates will inherit the setup on next git pull.

Anti-patterns

Composes with

• The always-on discipline baseline and the visual-authoring skills ship in this same package, so nothing extra is needed for them
• Microsoft-internal tooling (WorkIQ, Agency framework, org-report) is separate and only useful inside Microsoft's corporate network

Falsifiability

Sunset or revise this skill by 2027-01-30 (6 months) if any of the following fires:

• Any target plugin is renamed, moved, or deprecated upstream, making the emitted block stale. This fired once: the persona-axis Fabric bundles were retired into fabric-skills and the skill kept emitting all three for months. Verify each name with copilot plugin marketplace browse before emitting, under the account whose tenant owns the marketplace.
• Microsoft ships a new plugin in the same ecosystem that users consistently install alongside these (block is incomplete).
• The copilot plugin marketplace add CLI syntax changes (install flow is broken on emit).
• Two or more Users report the auto-install mode overwriting unrelated settings (safety rule failed).
