Added `usageCost :: Maybe Double` field to the `Usage` type to captur 2. Updated `FromJSON` instance to parse the optional `"cost"` field 3. Modified `ChatCompletionRequest` ToJSON instance to include `"usage": 4. Changed cost types from `Int` to `Double` throughout (engineOnCost ca 5. Updated `estimateCost` to use floating-point division instead of inte 6. Modified `runAgent` to use actual cost from API when available, conve 7. Added new test case for parsing usage with cost field **Omni/Agent/Worker.hs:** 1. Updated `runWithEngine` signature to return `Double` for cost 2. Changed `totalCostRef` from `IORef Int` to `IORef Double` 3. Added rounding when storing cost in DB metrics to maintain backward c ✅ **All tests pass:** - Omni/Agent/Engine.hs - 16 unit tests pass - Omni/Agent/Worker.hs - Builds successfully - Omni/Agent.hs - All integration tests pass - Omni/Jr.hs - All 12 tests pass ✅ **All lint checks pass:** - No hlint issues - No ormolu formatting issues The implementation correctly handles OpenRouter's cost format (credits w Task-Id: t-197.8 --- Omni/Agent/Worker.hs | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'Omni/Agent/Worker.hs') diff --git a/Omni/Agent/Worker.hs b/Omni/Agent/Worker.hs index 79cf3c8..2949ac3 100644 --- a/Omni/Agent/Worker.hs +++ b/Omni/Agent/Worker.hs @@ -98,8 +98,8 @@ processTask worker task = do endTime <- Data.Time.getCurrentTime say ("[worker] Agent exited with: " <> tshow exitCode) - -- Update the activity record with metrics - TaskCore.updateActivityMetrics activityId Nothing (Just endTime) (Just costCents) Nothing + -- Update the activity record with metrics (convert Double to Int by rounding) + TaskCore.updateActivityMetrics activityId Nothing (Just endTime) (Just (round costCents)) Nothing case exitCode of Exit.ExitSuccess -> do @@ -199,7 +199,7 @@ tryCommit repo msg = do -- | Run task using native Engine -- Returns (ExitCode, output text, cost in cents) -runWithEngine :: Core.Worker -> FilePath -> TaskCore.Task -> IO (Exit.ExitCode, Text, Int) +runWithEngine :: Core.Worker -> FilePath -> TaskCore.Task -> IO (Exit.ExitCode, Text, Double) runWithEngine worker repo task = do -- Read API key from environment maybeApiKey <- Env.lookupEnv "OPENROUTER_API_KEY" @@ -253,7 +253,7 @@ runWithEngine worker repo task = do TaskCore.insertAgentEvent tid sessionId eventType contentJson -- Build Engine config with callbacks - totalCostRef <- newIORef (0 :: Int) + totalCostRef <- newIORef (0 :: Double) let quiet = Core.workerQuiet worker sayLog msg = if quiet then putText msg else AgentLog.log msg engineCfg = -- cgit v1.2.3
