# Get Observability Summary

`GET /observability/summary`

Headline totals, previous-period trend, and daily spend series.

Separates total coding-harness spend from actual software-engineering spend
(``engineering_spend`` = total minus ``non_coding``).

## Query parameters

- `start_date` string, nullable — Range start (ISO date or datetime, UTC). Defaults to 30 days ago.
- `end_date` string, nullable — Range end (ISO date or datetime, UTC). Defaults to now.
- `scope` 'team' | 'personal' — ``team`` (default) aggregates the active team's coding-agent tasks; ``personal`` narrows to tasks on keys the requesting user created.

## Response `200`

Successful Response

- ObservabilitySummary — Headline totals for the overview, with a previous-period trend. ``engineering_spend`` excludes ``non_coding`` tasks; the gap between ``total_spend`` and ``engineering_spend`` is the "coding-agent traffic is not all software-engineering spend" finding the overview must surface.
  - `total_spend` number, required
  - `engineering_spend` number, required
  - `non_coding_spend` number, required
  - `routed_spend` number — Spend served via the Pioneer model router (USD).
  - `direct_spend` number — Spend on raw direct-model calls that bypass the router (USD).
  - `total_tokens` integer, required
  - `task_count` integer, required
  - `session_count` integer, required
  - `one_shot_count` integer, required
  - `active_keys` integer, required
  - `active_harnesses` integer, required
  - `previous_total_spend` number, required — Total spend over the immediately preceding window of equal length.
  - `spend_trend_pct` number, nullable — Percent change vs previous period; null when previous is zero.
  - `daily` SummaryDailyPoint[], required
    - `date` string, required — UTC calendar day, ``YYYY-MM-DD``.
    - `spend` number, required — Total coding-harness spend (USD) that day.
    - `engineering_spend` number, required — Spend that quarter excluding ``non_coding`` tasks (USD).
    - `routed_spend` number — Spend that day served via the model router (USD).
    - `direct_spend` number — Spend that day on raw direct-model calls (USD).
  - `meta` ObservabilityMeta, required — Data-quality envelope attached to every observability response. Lets the UI label boundaries instead of silently under-reporting: the category window (classification only runs over recent inline payloads), the per-harness payload coverage, and the earliest date harness attribution is available (before which no data exists, so a picker must not offer it).
    - `category_window_days` integer, required — Category classification only covers the last N days of inline payloads.
    - `category_window_start` string, date-time, required — UTC start of the category-classification window (now - category_window_days).
    - `coverage_start_date` string, date-time, required — Earliest UTC date with caller metadata / harness attribution; date ranges before this return nothing.
    - `harness_coverage` HarnessCoverage[], required — Per-harness category-coverage gating for UI labelling.
      - `harness` string, required
      - `coverage` 'full' | 'partial' | 'excluded', required
    - `generated_at` string, date-time, required — UTC time this response was computed.
