Classification , post-hoc; cannot change the reward
HARNESS_ERRORInfrastructure failure, the agent never ran properly. Not a signal about agent or task.
SubtypeResource Exhaustion / Credits Depleted
EvidenceAgent trajectory shows: (1) User message with full task instruction received at step 1, (2) Assistant response at step 2: \"Credit balance is too low\". The agent was unable to proceed with the task due to infrastructure resource constraints, not agent reasoning or task specification issues. Test output shows 31 failures across all major subsystems (OAuth, JWT authorizer, route scopes, Lambda config, IAM), indicating the task environment was misconfigured and the agent never had the opportunity to attempt fixes.
Root causeThe agent exhausted available credits/resources before it could attempt any diagnostic or remediation steps. The infrastructure constraint prevented the agent from executing the task, making it impossible to assess agent capability or task quality.
RecommendationN/A - This is an infrastructure/resource constraint issue, not a task specification problem. The task appears well-designed with clear multi-part bugs to diagnose. Re-run with sufficient resources allocated to the agent."

a teammate left mid-setup and the machine-to-machine reports API they were standing up is broken. the api gates `GET /reports` and `POST /reports` on the prod stage of an HTTP API v2 behind a Cognito JWT authorizer, with access tokens minted by Cognito's `client_credentials` OAuth flow. the pieces are all there (user pool `harbor-jwt-pool`, resource server `harbor-api` with scopes `read` and `write`, app client `harbor-jwt-client`, HTTP API `harbor-jwt-api`, a JWT authorizer wired to the pool, Lambda backend `harbor-jwt-backend` integrated to both routes) , they are wired wrong. fix it in place; recreating a resource is fine when its config can't be changed in place. a manifest of what exists is published under SSM at `/harbor/jwt/*` , read it. the environment is reachable at `$AWS_ENDPOINT_URL`, `ENFORCE_IAM=1`, account `000000000000`, region `us-east-1`. what "fixed" means: the verifier exercises the full M2M flow end to end. the client fetches an access token by POSTing `grant_type=client_credentials&scope=harbor-api/read harbor-api/write` to the cognito `/oauth2/token` endpoint with HTTP Basic auth (`client_id:client_secret` base64-encoded), which must return **HTTP 200** with an `access_token` that's a 3-segment JWT carrying `client_id` and a `scope` claim covering both scopes. then `GET <api-endpoint>/reports` and `POST <api-endpoint>/reports` with `Authorization: Bearer <token>` must each return **HTTP 200** with a JSON body (the lambda echoes `ok: true`, method, route, claims). the same requests with no `Authorization` header or a malformed bearer must come back as **401**. a request whose token carries only the *other* scope , `GET /reports` with a `harbor-api/write`-only token, or `POST /reports` with a `harbor-api/read`-only token , must come back as **403**. you'll have to diagnose the bugs yourself , there are several, they're independent, and each is enough to keep the api from working. inspect what's actually deployed (`describe-*` everything , user pool client, resource server, authorizer, every route, the integration, the stage, the lambda), drive the token endpoint and the api directly and read what comes back. the bugs here are the usual suspects for this pattern: IAM, the JWT authorizer config (issuer, audience, identity source, scopes), the Cognito app client wiring (OAuth flow, secret, allowed scopes), the HTTP API v2 route/integration coupling (route key, payload format version), and the stage deployment lifecycle. one procedural gotcha worth stating outright since forgetting it makes a correct fix look broken: HTTP API v2 only serves route/integration changes if the stage has auto_deploy=true or a fresh deployment is created. fixing all-but-one of the bugs still leaves the API broken , the check is the behaviour, not a checklist.
