feat(usage): add provider, model, and day cache metrics with price coverage#2365chilung-cgu wants to merge 7 commits into
Conversation
📝 WalkthroughWalkthroughUsage summaries centralize entry cost calculation. Daily, model, provider, and account aggregations report token, cache, cache-hit-rate, pricing, and estimated-cost metrics. Filtering canonicalizes model identities and projects matching combo attempts. Tests cover mixed priced and unpriced attempts. ChangesUsage metrics aggregation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds useful usage and cache metrics, but the current implementation can report inconsistent estimated costs and may produce misleading or undeclared cache-related API data in edge cases. These bounded correctness and API-shape issues should be fixed or explicitly accepted before merge. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@src/usage/summary.ts`:
- Around line 571-578: Refactor summarizeUsage to compute each entry’s
CostEstimate once, including serviceTierContext and the existing attempt/request
estimation logic, then reuse those results across the totals aggregation,
buildDayGrid, buildModels, buildProviders, and buildAccounts paths. Update these
consumers to accept or access the cached estimate while preserving current null
and cost aggregation behavior.
- Around line 450-457: Update the cacheHitRate aggregation in
src/usage/summary.ts at lines 450-457 and the equivalent aggregation sites at
lines 481-483, 629-631, 688-690, and 811-813 to track whether any cache
telemetry field was observed, returning null when none was reported while
preserving zero for explicitly reported zero values. Update the expectation in
tests/usage-summary.test.ts at lines 989-992 to expect null for the fixture
without cache fields.
- Around line 574-596: Update the combo-cost handling in the summary flow to
evaluate each attempt with estimateAttemptCost instead of treating
estimateComboCost failure as an all-or-nothing result. Add costs for matched
attempts and record only unmatched attempts in unpricedRequestsByModel,
preserving accurate priceCoverageRatio. Apply the same partial-cost behavior in
addEstimatedCost and buildDayGrid, and add a regression test covering a combo
with both priced and unpriced attempts.
- Around line 428-446: The single-target cost attribution in the summary flow
derives keys with antigravityUsageModel instead of usageModelIdentity, causing
unknown Antigravity models to mismatch their created rows and lose estimated
cost updates. Update the single-target paths in the relevant summary logic,
including the branch shown near the estimate handling and the corresponding path
used by buildModels, to derive model keys through usageModelIdentity while
preserving the existing provider and cost accumulation behavior.
- Around line 395-406: Extract the repeated cache-token derivation into a shared
cacheTokensFromUsage helper, preserving the existing precedence and clamping
rules for read and creation values. Replace the duplicated logic in the current
summary aggregation and the buildModels, buildProviders, and buildAccounts flows
with calls to this helper, then apply its returned read and creation values to
each row’s counters.
Apply the same fix in `@src/usage/summary.ts` around lines 712 - 719: The provider
mirror is covered by this consolidated cache-derivation comment; its other
concerns remain covered by the kept root comments.
In `@tests/usage-summary.test.ts`:
- Around line 1004-1013: Extend the daily usage assertions around summary.days
and daySonnet to verify estimatedCostUsd is greater than zero, ensuring daily
cost attribution reaches the model despite the identity-key lookup; also add a
focused assertion for the unpriced-model daily entry that cacheHitRate is null
when cache telemetry is unavailable.
- Around line 980-987: Make the price coverage assertion in the summarizeUsage
test deterministic by removing the sonnet priceCoverageRatio expectation, unless
summarizeUsage is explicitly updated to accept fixture pricing overlays and the
test passes them. Keep price-resolution coverage in a separate test rather than
relying on generated metadata or the mutable activeUserCostOverlays registry.

In `@src/usage/summary.ts`:
- Around line 1104-1110: Update the filtering logic around usageModelIdentity
and filtered.push so the projected entry recomputes parent usage and totalTokens
from retained attempts, while preserving cache and reasoning counters. Ensure
summarizeUsage and day totals use these projected values consistently with model
rows, and add a focused filtered-combo regression test near the existing
usage-summary tests with parent usage present.
- Around line 572-585: The daily overflow aggregation must preserve whether
cache-read values were explicitly observed and use calculateCacheHitRate for the
final cacheHitRate. Track cacheObserved while merging overflow models so
explicit zero reads return 0 and reads exceeding inputTokens are capped
according to the helper; add focused breakdown-cap regression coverage for both
cases near the existing summary tests.

assertion to also verify the exported cache-read counter, including the overflow
case where the rate remains clamped while the preserved counter must retain its
original value.

Use one unmetered classification for all cost aggregations.
aggregateAttemptUsage can mark a combo "unreported" when one attempt has no usage, even when another attempt has usage and a matched price. addEstimatedCost then excludes the entry from totals.estimatedCostUsd, while the day, model, and provider aggregations still include the priced attempt cost.
Carry the same isUnmetered decision in EntryCostInfo and apply it to every cost aggregation path. Add a regression test for one unreported attempt and one priced attempt.
