Summary

The /insights built-in command hardcodes claude-opus-5 as its model, ignoring the ANTHROPIC_MODEL environment variable and the user's selected model.

Steps to Reproduce

Set ANTHROPIC_MODEL=claude-sonnet-4-6 in shell environment (e.g. .zshrc)
Confirm selected model is Sonnet 4.6 in the Claude Code session
Run /insights
Observe API request goes to claude-opus-5

Expected Behavior

/insights should respect ANTHROPIC_MODEL (or the session-selected model) the same way normal prompts do.

Actual Behavior

The command uses claude-opus-5 regardless of configured model. Confirmed via strings on the binary — buildInsightsResponsePrompt and claude-opus-5 are co-located, indicating the model is pinned at compile time.

Environment

Claude Code version: 2.1.226
Platform: macOS (darwin arm64)
ANTHROPIC_MODEL: claude-sonnet-4-6

Impact

Users who configure a specific model (cost, latency, or policy reasons) get silently billed at Opus 5 rates whenever they use /insights. No warning or override mechanism is exposed.
