Newer Anthropic models perform worse with some edit tools
Armin Ronacher reports that newer Claude models such as Opus 4.8 and Sonnet 5 sometimes generate malformed arguments for Pi’s edit tool, causing tool calls to be rejected. The issue appears in newer Anthropic models but not older ones, suggesting model-specific training for Claude Code’s edit workflow may reduce compatibility with third-party coding harnesses.
