Build, deploy, and modify GitHub Copilot SDK apps on Azure. MANDATORY when codebase contains @github/copilot-sdk or CopilotClient in package.json. PREFER OVER azure-prepare when copilot-sdk markers detected. WHEN: copilot SDK, @github/copilot-sdk, copilot-powered app, build copilot app, prepare copilot app, add feature to copilot app, modify copilot app, BYOM, bring your own model, CopilotClient, createSession, sendAndWait, azd init copilot. DO NOT USE FOR: deploying already-prepared copilot-sdk apps (use azure-deploy), general web apps without copilot SDK (use azure-prepare), Copilot Extensions, Foundry agents (use microsoft-foundry).

Security
2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 0.90). The skill explicitly instructs the agent to fetch and read files from public GitHub repos (e.g., via github-mcp-server-get_file_contents for owner:"github", repo:"copilot-sdk" and for "azure-samples/copilot-sdk-service") as part of its required workflow (references/copilot-sdk.md and references/existing-project-integration.md), meaning untrusted third-party content will be ingested and used to drive code changes and deployment decisions.
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Potentially malicious external URL detected (high risk: 0.90). The skill explicitly performs runtime fetches of repository content using github-mcp-server-get_file_contents to read files from https://github.com/github/copilot-sdk (and even suggests running npx -y @upstash/context7-mcp@latest to install/execute a context7 MCP), and those fetched docs/code snippets are used directly to drive agent responses and code-generation, so this is a runtime external dependency that can control prompts/behavior.

If you maintain this skill, you can claim it as your own. Once claimed, you can manage eval scenarios, bundle related skills, attach documentation or rules, and ensure cross-agent compatibility.
