Since Claude Code 2.1.77 a PreToolUse hook's allow cannot override a deny or ask rule. Find the matching rule with /permissions, then move the policy into the hook.

When a Stop hook, /goal condition, or CI-style gate demands a check the agent's environment can never pass, Claude Code keeps re-running it until the 8-consecutive-block cap (2.1.143+) ends the turn. Here is why it happens and the hook patterns that let the agent give up correctly.

Microsoft Agent Framework .NET 1.21.0 ships Microsoft.Agents.AI.LocalCodeAct 1.21.0-preview.260911.1, which no longer lets the CodeAct Python subprocess inherit the parent environment when Environment is null. On 1.20, generated code could read every host variable, API keys included.

Agent Execution Timed Out, ERROR_EXTENSION_HOST_TIMEOUT and Timeout waiting for EverythingProvider are one failure: Cursor's extension host missed its 60 s startup budget. Read exthost.log first, then fix the right cause: endpoint security, a VPN capturing loopback, a corrupt state database, or an extension.

Your MCP URL 307/308-redirects to another host, the client follows it, the Authorization header is stripped, and the target answers 401. Register the final URL.

OAuth succeeded but every MCP call gets 401 invalid_token? Make the PRM resource, the token's aud and your validator agree on one canonical server URL.

Use Cursor's /goal command to keep a cloud agent working toward one finish line across many turns. Covers writing a verifiable objective, pinning a Custom Mode playbook, pairing it with /loop and subscriptions, the CLI's durable goals, and how to stop a goal that ignores Stop.

Since August 21, 2026 mentioning @GitHub in Slack starts a Copilot cloud agent session the whole channel can steer. Here is the setup, the Slack Code channel model, why the pull request comes from an app identity instead of you, what the thread context capture actually exposes, and how the two separate billing meters add up.

Cursor's Self-Hosted Machines, shipped September 2, 2026, move Cloud Agent tool calls onto hardware you own while inference stays in Cursor's cloud. The agent worker CLI, My Machines vs Team Pools, the three outbound hosts, and the data that still leaves your network.

Claude Code 2.1.260 adds a likely-cause diagnosis to the Prompt cache (main) line in /usage and to the prompt_cache status line object. Instead of just counting misses, it tells you whether the tool set changed, the system prompt changed, or the TTL expired.
