A September 2026 comparison of GitHub Copilot code review, Cursor Bugbot, and anthropics/claude-code-action@v1 running the code-review plugin: what each one reads, what it skips, what it costs per review, and which to put on which repo.

Claude Code 2.1.274 still loads only CLAUDE.md. Bridge AGENTS.md with an @AGENTS.md import or a symlink, then avoid the three traps: imports that don't expand from a subdirectory, symlinks that Windows checks out as a 9-byte text file, and Edit refusing to write through the link. Includes a CI check and a SessionStart hook for repos you don't own.

"File is configured to be ignored by Copilot" or "Some files were excluded from the context" means a content exclusion rule matched. How to find the rule, why globs over-match, and how to narrow it.

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.
