hoangsonww Daily Budget Check
A fast daily pulse: are you on pace against today's budget?
Input
The user provides: $ARGUMENTS
This is the daily budget in dollars — e.g. "5" or "$5/day". If omitted, ask
for one or derive it from a monthly budget (monthly / days_in_month) and state the
assumption.
Data Sources
| Endpoint | Returns |
|---|---|
GET /api/pricing/cost |
{ total_cost, breakdown: [{ model, input_tokens, output_tokens, cache_read_tokens, cache_write_tokens, cost, matched_rule }] } — fleet-wide spend and the avg cost-per-session used to value today's sessions |
GET /api/sessions?limit=200 |
Session list with inline cost and started_at — filter to today (DATE(started_at) = today) to isolate today's spend |
Method
Spend has no per-day field, so isolate today from the session list:
- Today's sessions = sessions whose
started_atis today (local date). - Today's spend = sum of inline
costover today's sessions. If inlinecostis absent for some rows, fall back totoday_session_count × (total_cost / total_session_count)and flag it as approximate. - Pace:
fraction_of_day_elapsed = hours_since_midnight / 24.expected_by_now = daily_budget × fraction_of_day_elapsed. - Pace delta =
today_spend − expected_by_now(▲ ahead of budget / ▼ behind). - End-of-day projection:
projected_today = today_spend / fraction_of_day_elapsed(linear extrapolation of the current pace). Guard against tinyfraction_of_day_elapsedearly in the day — if under ~0.1, label the projection low-confidence. - Projected overage =
projected_today − daily_budget(positive = over).
Report Sections
1. Today vs budget
One headline line: today's spend / daily budget, and the percent consumed. Verdict: under / on pace / over.
2. Pace
expected_by_now vs actual today_spend, the ▲/▼ pace delta, and the fraction of the day elapsed.
3. End-of-day projection
projected_today and the projected overage/headroom vs the daily budget. Note the confidence (low early in the day).
4. Today's drivers
Today's sessions ranked by cost (top 5): name/id, model, cost. Surface any premium-model session inflating the day.
5. Nudge
If projected over: one concrete cut (route the priciest session type cheaper — see model-savings; or arm a token_threshold rule via budget-set). If under: confirm headroom and the remaining daily allowance.
Output
Compact Markdown — this is a daily check-in, keep it tight. Currency as USD to 4 decimal places; pace deltas with ▲/▼. Lead with the verdict line.
