| description | Report Claude Code model routing + fallback usage across local session transcripts. Produces a per-model table (Share of turns · Turns Hit · Fallbacks · FB Rate) split into two scopes — Main Session Threads vs Workflows/Subagents (never merged) — plus a "last 10 main-thread turns" routing glance, a Refusals/API-error tally (safeguard/AUP blocks, rate limits, auth failures; reason×scope), and a narrative (span, by-date, fallback direction). Defaults to the last 12 hours; scope to any time window and/or a specific session id. Use when the user asks what model(s) a session/subagents ran on, wants a fallback report, asks whether anything fell back to a different model, asks about refusals / safeguard / AUP blocks / how often a model declined or errored, or asks "what percentage on what model". |
