A claude -p run on Opus with an API key gives up after three consecutive 529s, about 1.5 seconds of backoff, no matter what CLAUDE_CODE_MAX_RETRIES says. Add --fallback-model, set CLAUDE_CODE_RETRY_WATCHDOG=1 with a max wait, or widen the 529 backoff with the OVERLOADED_RETRY delay variables. Checked against Claude Code 2.1.309.

Claude Code 2.1.289 and earlier resend every screenshot on every turn, so one refused request means every later turn is refused too. Update to 2.1.290+ and resume with claude --continue; the client then trims the oldest images to 510, 255, then 127. On an old build, /compact or /clear. Then stop the screenshots piling up.

Turn on GitHub Copilot computer use in Copilot CLI and the Copilot app on macOS and Windows, grant the macOS Accessibility and Screen Recording permissions, approve apps per session or always, write prompts that keep the agent read-only, and lock it down with deny rules and the features.computerUse managed setting.

ModelContextProtocol 2.3.0, released October 20, 2026, changes McpClient.ServerInfo from Implementation to Implementation? because 2026-07-28 servers may omit their identity from server/discover. Here is why, what breaks under warnings-as-errors, and the one-line fix.

On container protocol 2.0.0, Foundry hosted agents isolate conversations and sessions per Entra caller by default. When your own backend fronts many end users, you delegate with x-ms-user-identity, grant a custom impersonation role, and key everything your container stores by session ID plus user ID. Here is the C# for each layer and the traps that leak data between users.

Since Claude Code v2.1.295, a command or HTTP hook can set onFailure to "block" so a guard that crashes, times out, cannot start or prints invalid JSON stops the tool call instead of waving it through. Here is the config, what counts as a failure, the events where it does nothing, and the exit-0 trap no setting can catch.

Claude Code v2.1.296 lets a subagent auto-compact earlier than the main conversation. Set autoCompactWindow in the subagent's frontmatter or --agents JSON as a plain integer from 100000 to 1000000, and watch out for the 200k parsing trap, the CLAUDE_CODE_AUTO_COMPACT_WINDOW override, and the --agent session mode where the field does nothing.

Wire Cursor Rollouts (launched September 23, 2026) to your CI and to Datadog so every PR, including the ones a cloud agent wrote, gets a rollout plan before merge and per-environment checks at deploy, 20 minutes, 1 hour, 1 day and 3 days. Covers the DeploymentsService API, a GitHub Actions job, the Datadog MCP data source, and the gotchas that leave changes stuck in Pending.

A practical setup for Cursor Projects: prepare the repo so every worker starts warm, seed the Project's shared Context with a plan, conventions and a slice ledger, cut the work into disjoint PR-sized slices, and let subscriptions keep it moving. Covers Cursor 3.24, plan and admin gates, and the gotchas of a Context that lives outside git.

Request a GitHub Copilot code review from a script with the REST requested_reviewers endpoint, the GraphQL requestReviewsByLogin mutation, or gh pr edit, then control whether it runs at Lite or Balanced effort. Covers the bot login, the effort precedence chain, why the per-request effort field announced on October 2, 2026 is not in the published schemas yet, and how to read the effort that actually ran.
