The experimental /rubber-duck command in VS Code 1.135 hands the agent's plan, code, and tests to a model from another family for review. GPT-5.4 critiques Claude, and the cross-family choice is the whole point.

Agent Plugins 1.0.0 standardizes exactly two component types: skills and MCP servers. Slash commands, hooks, subagents, rules, LSP servers, permission config and secrets all stay vendor-specific. Here is the field-by-field matrix across Claude Code, Cursor, Copilot and Codex, and which layout to author in.

Mapperly is the default for new .NET code: it matches hand-written speed, survives Native AOT, and catches unmapped members at build time. AutoMapper still wins on ProjectTo. Benchmarks and license thresholds included.

GitHub's August 27 and August 28, 2026 changelogs remove the 20,000 line review cap, start reviewing bot-authored PRs, and flip the default review effort from Lite to Balanced on September 28. All three push AI credit consumption up in the same month.

Firebase Auth restores the Android session from a private SharedPreferences file with no network call, so a release-only sign-out is never broken persistence. It is a different google-services.json, a rejected token refresh, App Check, or your own catch block.

build_runner fails to compile because source_gen 3.1.0 or 4.0.0 calls an analyzer API removed in analyzer 8.4.0. Upgrade the generator that pins source_gen below 4.0.1.

Claude Code 2.1.251 adds PreModelSwitch and PostModelSwitch hook events. The matcher fires on the canonical name of the model you are switching to, and exit code 2 cancels the switch.

The check-then-insert in your handler is not atomic. Catch PostgresException with SqlState 23505, or collapse the whole thing into one INSERT ... ON CONFLICT statement. EnableRetryOnFailure will not help.

EF Core's Migrate() always checks whether the database exists and creates it if not, from a hardcoded master connection. Grant CREATE ANY DATABASE, fix the login's access to the existing database, or ship an idempotent SQL script instead.

iOS builds set DynamicCodeSupport=false, so EF Core refuses to build the model even though you never enabled NativeAOT. Ship a compiled model plus precompiled queries, or turn the interpreter back on.
