Each row is one Claude Code session (sessionId). Avg context approximates the running prompt size by summing input + cache_read tokens, divided by turns. Long conversations with low cache hit ratios are usually the ones burning the most context.
| Project / Session | Source | Turns | Total Tokens | Avg Context / Turn | Cache Hit | Duration | Cost |

Duration is wall-clock time between first and last assistant message. Long durations on few-turn sessions usually mean the session was left open idle.
Daily attribution mix. Stacked bars show cost composition per day across each dimension. Hover for exact values.
Days where you didn't run Claude show as gaps. Earliest data: starts of your usage history; we only see local + cowork from this machine.

Cache hit ratio = cache_read / (cache_read + cache_create). Low ratios suggest workflows that fetch fresh data each time — optimization targets. Top 10 by cost shown by default; toggle "show all" to expand.
Cost per turn is split evenly across tools used in that turn (rough proxy — a turn with 3 tools attributes 1/3 to each). Top 15 by cost shown by default.

| Subagent type | Invocations | Approx Cost |

Subagents (Agent tool calls with subagent_type) run as separate API conversations. Costs here approximate parent-turn attribution; actual subagent compute appears in the subagent JSONL files and is included in the totals.
What you actually paid (Standard) vs hypothetical cost without prompt caching. Higher % saved = better ROI from cache reuse.

Methodology: Costs computed from raw JSONL using Anthropic published rates (Opus $5/$25, Sonnet $3/$15, Haiku $1/$5 per 1M; cache writes ×1.25, cache reads ×0.10). Totals on this page may exceed dashboard.html because every assistant turn (including autocompaction summaries and subagent compute) is counted individually here for attribution. All numbers are API-equivalent value — you actually pay $100/mo flat under Max 5×.
