The agents couldn't run bash commands.

Code Sample

async with GitHubCopilotAgent(
            client=self._client,
            name="V2 Expert",
            instructions="",
            default_options={
                "model": "gpt-5.3-codex",
                "timeout": 3600,
                "on_permission_request": lambda req, env: PermissionDecisionApproveForSession(),
            },
        ) as agent:
            session = self._sessions.get(input.v2_dir)
            if session is None:
                session = AgentSession()
                self._sessions[input.v2_dir] = session
            response = await agent.run(prompt, session=session)

Agent analysis

Repro: PermissionDecisionApproveForSession() from copilot.generated.rpc with no approval arg serializes to {"kind": "approve-for-session"} missing the approval key; the Copilot CLI binary crashes with "Cannot read properties of undefined (reading 'commandIdentifiers')". The agent-framework passes permission decisions through without validation in _build_session_kwargs() at python/packages/github_copilot/agent_framework_github_copilot/_agent.py:1230. Fix could validate the decision in the agent's permission flow or default to PermissionDecisionApproveOnce when approval is None. Minimal repro: construct GitHubCopilotAgent with on_permission_request returning PermissionDecisionApproveForSession() and trigger a tool that requires permission.
