Each episode highlights what changed, how to use it, and why it matters.

Latest Episodes:

Claude Code Fixes a 10GB MCP Leak and a Sneaky Resume Bug May 07, 2026

Show notes

This episode digs into the v2.1.132 Claude Code update, including a stdio MCP memory leak that could balloon long sessions past 10GB, plus the practical differences between stdio and HTTP transport. It also covers new session-aware Bash env vars, a terminal escape hatch for alternate screen mode, and a permission-mode bug that could quietly override your intent when resuming plan-mode sessions.

Claude Code 2.1.129 Turns Plugins Into Shareable Artifacts May 06, 2026

Show notes

This episode breaks down how Claude Code v2.1.129 changes plugin loading with URL-based zip installs, moving plugins from local setup to a true distribution model. It also explores the new experimental themes and monitors fields, and the security tradeoffs that come with treating plugins like packaged software.

Claude Code Fixes a Silent Worktree Bug May 05, 2026

Show notes

This episode breaks down a subtle Git behavior in Claude Code v2.1.128 where new worktrees now branch from local HEAD instead of origin/default-branch, preventing unpushed commits from being skipped. It also covers related reliability improvements, including OTEL isolation for subprocesses and better handling of parallel tool calls.

Claude Ultrareview Turns AI Feedback Into a Merge Gate May 04, 2026

Show notes

This episode explores how Claude Code’s `ultrareview` command uses exit codes, streamed output, and PR targeting to make AI review behave like a real CI check. It also digs into the multi-agent verification model, cost tradeoffs, and the network constraints teams need to consider before wiring it into GitHub Actions.

Anthropic’s xhigh: Claude Code’s New Default Gear May 03, 2026

Show notes

We break down Anthropic’s new xhigh effort level for Claude Code on Opus 4.7, why it now defaults for Max subscribers, and how the new slider and config flow make it easier to use.

The discussion also covers when deeper reasoning is worth the extra latency and cost, plus how to spot the tasks where xhigh really pays off.

Claude Code v2.1.126 Finally Trusts Your Model Gateway May 02, 2026

Show notes

Claude Code now asks your configured ANTHROPIC_BASE_URL for /v1/models, so the model picker reflects the IDs your gateway actually exposes instead of a hardcoded Anthropic-only list. The episode breaks down why that matters for LiteLLM, Bedrock, and other proxies, plus the catch: the backend still has to return truthful model names or the client will pass them through verbatim.

Claude Code Gets a Clean Purge and Safer OAuth Login May 01, 2026

Show notes

We break down the new claude project purge command, which wipes stale transcripts, tasks, file history, and project config so broken project state can be reset cleanly. The episode also covers the expanded behavior of --dangerously-skip-permissions, the new direct OAuth code paste flow for login failures, and a subtle policy bug fix affecting Claude Code memory.

Claude Code’s Hidden Bedrock Cost Lever Apr 30, 2026

Show notes

April 29, 2026 brought a small Claude Code update with big budget implications: the new ANTHROPIC_BEDROCK_SERVICE_TIER setting lets Bedrock users choose default, flex, or priority and sends that choice as the X-Amzn-Bedrock-Service-Tier header. The episode breaks down when each tier makes sense, why latency and throughput guarantees matter, and how to avoid overpaying for interactive and batch workloads.

Claude Code v2.1.121: Instant MCP Tools and Tool-Output Hooks Apr 29, 2026

Show notes

This episode digs into two major v2.1.121 changes in Claude Code: the alwaysLoad flag for loading selected MCP server tools at session start, and a widened PostToolUse hook that can rewrite outputs from built-in tools like bash and file reads. It also covers the practical tradeoffs around context, trust boundaries, and the release’s memory leak fixes.

Claude Code Ultrareview Goes CI-Native Apr 28, 2026

Show notes

We break down how ultrareview moved from an interactive slash command to a real CLI that can run in scripts, Make targets, and GitHub Actions as a potential build gate. The episode also covers JSON output for automation, the trust and latency tradeoffs of model-based PR checks, plus smaller quality-of-life updates like PowerShell fallback on Windows and better GitHub attribution.
