What changed

Material regressions ranked by severity and affected call volume.

Current 7 days compared with the previous equal window

Stable against baseline

No material tool regressions detected

Tools with enough activity were checked for higher failure rates, available p95 latency regressions, more no-results, and increased loop pressure.

Review the tool comparison for absolute hotspots that may still need a product threshold.

Investigate

Regression checks require at least 3 calls in both windows. Latency is flagged at +20%; failure and no-result rates are flagged at +1 and +3 points respectively.

Execution volume

Successful calls, no-results, and failures combined.

Tool comparison

Each change is measured against the previous equal window; latency appears only where detailed timing exists.

Interpretation notes

The data has known edges that change what a chart means.

Blocked loops are invisible: Rate-limited and identical-argument calls are rejected before telemetry fires.
NoResults is not downtime: It remains a failed tool outcome, but is separated from runtime reliability here.
Preview volume lives elsewhere: Preview and threadless chats reach PostHog but are intentionally absent from Postgres.
Latency is partially instrumented: Saved tool parts provide production outcomes and volume; duration appears only on calls with detailed telemetry.
Partial turns are retained: They remain in volume counts but are excluded from failures and latency percentiles.
Comparisons use equal windows: Every delta compares the selected period with the immediately preceding period under the same tool and team filters.
