👋 Hi @eguzchin-isoftwareiq — thanks for the report!

Your issue stems from a documented breaking change introduced in v1.11.1 (commit e3b64fd, PR #6729) titled '[BREAKING] Make all AgentSkillsProvider tools require approval by default'. In v1.10, load_skill and read_skill_resource were auto-invoked by FunctionInvokingChatClient, but starting in v1.11.1 all skill tools are wrapped with ApprovalRequiredAIFunction and require explicit approval handling. The fix is to add .UseToolApproval(new ToolAprovalAgentOptions { AutoAprovalRules = [AgentSkillsProvider.AllToolsAutoApprovalRule] }) to your agent builder chain, as shown in the updated Agent_Step01_FileBasedSkills sample.

If you still believe there is a framework issue here, please reply with the exact import/class or method you are using, the version, and a minimal snippet that shows the failure. 🙏

.UseToolApproval(new ToolAprovalAgentOptions { AutoAprovalRules = [AgentSkillsProvider.AllToolsAutoApprovalRule] })

new ToolApprovalAgentOptions..

Work fine if I disable ChatHistoryProvider ( CosmosChatHistoryProvider used )

With CosmosChatHistoryProvider - exception
{"ToolApprovalRequestContent found with FunctionCall.CallId(s) 'call_8P4YtPM7bSnqpYH1KnLb5sH5' that have no matching ToolApprovalResponseContent."}

require explicit approval handling.

I think - bad idea
extra requests between the model and the client, which are not needed in every application

I tested the Agent_Step01_FileBasedSkills sample with version 1.10, and it works as expected.

I then tested the same sample with versions 1.11.1 and 1.13, and both exhibit the same behavior: the skill is no longer invoked.

However, if I explicitly create an agent session and pass it when running the agent, the sample works correctly and the skill is invoked in both versions.
