Claude Code sometimes emits a stray court token and raw <invoke> as plain text instead of running Read/Edit/Bash — a malformed tool call that never executes. How to tell it from a hung shell or a 'could not be parsed' error, on long Opus 4.8 sessions.
Reading Anthropic's postmortem and the DEV operational report in the same week reveals that Claude Code's quality degradation and Max weekly quota exhaustion are not separate incidents—they're two sides of the same quality×cost design decisions. A timeline and operational priority walkthrough.
Anthropic Labs released Claude Design on April 17, 2026 — a new design product that reads your codebase and existing design files to generate prototypes, slides, and landing pages. Here is a feature comparison with Figma and Canva, and a scenario-by-scenario guide to which tool to open when.
Measured: Opus 4.7 burns 1.2-1.45x tokens vs 4.6 in community benchmarks (Bill Chambers' Tokenomics Leaderboard, Claude Code Camp), beating Anthropic's official 1.0-1.35x range. CLAUDE.md alone hits 1.4-1.45x.

Breakdown of the Claude Code quality-regression issue: an AMD/IREE developer analyzed 17,871 thinking blocks and 234,760 tool calls, linking adaptive-thinking shrinkage and redaction changes to worse coding behavior.
Anthropic expands its partnership with Google and Broadcom to secure multi-gigawatt TPU infrastructure targeting 2027 operations. Annual revenue run rate surpasses $30B, with enterprise customers spending over $1M exceeding 1,000.
