AKS-Lab-GitHubCopilot: Skill for Claude Code

Skill: GitHub Copilot SDK on gpt-5.5

Reflects the actual agent-framework[github-copilot] 1.3.x API installed in this repo. Earlier GitHubCopilotChatClient / ChatAgent(client=...) syntax is not valid here.

The two imports

from agent_framework.github import GitHubCopilotAgent, GitHubCopilotOptions
from copilot.generated.rpc import PermissionDecisionApproveOnce
from copilot.session import PermissionRequestResult

from src.shared.copilot import build_copilot_client

The one builder shape

def _approve_all(_request: object, _context: dict[str, str]) -> PermissionRequestResult:
    return PermissionDecisionApproveOnce()


async def build_agent(settings: Settings) -> _RunnableAgent:
    agent = GitHubCopilotAgent(
        instructions=SYSTEM_PROMPT,
        client=build_copilot_client(),
        name="<name>",
        description="...",
        tools=list(TOOLS),                       # local @tool functions, NEVER MCP
        default_options=GitHubCopilotOptions(
            model=settings.copilot_model,        # default "gpt-5.5"
            timeout=settings.copilot_timeout_seconds,
            on_permission_request=_approve_all,  # MANDATORY — see §Permissions
            mcp_servers={                        # specialists only; orchestrator omits this
                "<key>": {
                    "type": "http",
                    "url": settings.<which>_mcp_url,
                    "tools": ["*"],
                    "timeout": int(settings.copilot_timeout_seconds * 1000),
                },
            },
        ),
    )
    return _RunnableAgent(agent=agent)

_RunnableAgent is a @dataclass(frozen=True) adapter exposing async def run(self, message: str) -> AgentResponse[None]. The shared make_app calls .run(req.goal) on it.

Permissions (do NOT skip)

The Copilot SDK runs every tool call through a permission gate. The handler must return PermissionDecisionApproveOnce(). Without a handler, every call returns:
