crestapps-core-copilot-orchestrator

Skill for the GitHub Copilot orchestrator in CrestApps.Core 2.0, a named IOrchestrator ("copilot") built on the GitHub Copilot SDK. Covers AddCopilotOrchestrator and AddCoreAICopilotOrchestrator registration, the automatic Copilot CLI acquisition with its shared cache and npm registry MSBuild properties, binding CopilotOptions yourself, the NotConfigured, GitHubOAuth and ApiKey (BYOK) authentication modes and what each requires, implementing ICopilotCredentialStore or using JsonFileCopilotCredentialStore, GitHubOAuthService authorization, callback state validation, token refresh and model listing, CopilotSessionMetadata model, permission and reasoning-effort overrides, how tools reach the SDK, and its limits around MCP tools, deployments and usage metering. Use it when running profiles on a Copilot subscription or an OpenAI-compatible BYOK endpoint through Copilot, or when Copilot reports it is not configured.

# CrestApps.Core Copilot Orchestrator

`CrestApps.Core.AI.Copilot` adds `CopilotOrchestrator`, an `IOrchestrator` named `"copilot"` (title **Copilot**), which runs a turn through the GitHub Copilot SDK and its CLI instead of the default pipeline.

## Guidelines

- Choose GitHub OAuth when each user brings a Copilot subscription. Choose `ApiKey` (BYOK) for one shared OpenAI-compatible, Azure or Anthropic endpoint.
- Treat `NotConfigured` as intentionally disabled; editors should show a warning instead of Copilot fields while it is selected.
- Bind `CopilotOptions` yourself; the package reads no configuration section.
- GitHub OAuth needs an `ICopilotCredentialStore`. BYOK does not.
- Copilot does not use AI connections, deployments, deployment capabilities or deployment model parameters, and its SDK-managed requests are not recorded by usage metering.
