Customizing CLAUDE.md improves Opus 5 coding performance

A developer shared a CLAUDE.md configuration fix that resolves usability issues with Opus 5 during non-trivial tasks. By explicitly defining model routing and establishing rules to spawn sub-agents and headless workers after validating execution plans, heavy coding workflows become significantly more structured and reliable.

// ANALYSIS

Directing sub-agent delegation and model routing via workspace configuration files is rapidly becoming a best practice for complex agentic workflows.

–Explicit workflow rules in system prompts keep heavy reasoning models on track.
–Deferring sub-agent spawning until post-plan validation prevents wasted computational cycles.
–Granular control over model routing optimizes both cost and task execution speed.
