Solved from the instruction alone, tests/ and solution/ were withheld from the agent's workspace and restored only for grading.
Reward = tests/test.sh exit code (0 → resolved); the classification below is post-hoc and cannot change it.
Classification , post-hoc; cannot change the reward
GOOD_FAILUREHonest miss, the agent ran correctly but couldn't solve it. Expected for a hard task; the task is sound.
SubtypeIncomplete Implementation
EvidenceTest results show 11/15 tests passed. Specifically failing tests: test_kms_key_policy_grants_rotator_role, test_rotator_lambda_allows_secretsmanager_invoke, test_parent_role_grants_sync2_managed_rule_perms, test_child_role_can_rotate_and_publish. Agent successfully created: KMS key (alias/app-rotation-key), secret (app/db/password), lambdas (secrets-rotator, notification-lambda), state machines (rotation-orchestrator, rotation-child), EventBridge bus and rule. But failed to: (1) Add rotator role to KMS key policy for Decrypt/GenerateDataKey, (2) Attach resource-based policy to Lambda allowing secretsmanager.amazonaws.com, (3) Grant parent role events:PutRule/PutTargets/DescribeRule permissions, (4) Grant child role secretsmanager:RotateSecret and events:PutEvents."
Root causeThe agent completed the resource creation phase but did not fully wire IAM permissions as specified in the instruction. The required policy configurations for .sync:2 EventBridge managed rules and resource-based Lambda policies were not implemented, despite being explicitly described in the instruction.
RecommendationN/A - task is fine

ok so we need a secrets rotation pipeline on localstack and right now the box is empty. localstack is at `http://localstack:4566`, creds are already exported (`AWS_ACCESS_KEY_ID=test`, same for secret, region `us-east-1`), you've got `aws`, `python3`, `boto3`, `jq`, `zip`, `curl`. build the whole thing. the app reads its db password from secrets manager. we need it rotatable on demand via step functions, and every successful rotation has to notify a downstream lambda. no humans in the loop. shape of it: - a parent state machine is the only entry point. it doesn't do the actual work , it hands off to a child SM and waits for it to finish. - the child SM does two things: kicks off rotation, then puts a `RotationComplete` event onto a custom eventbridge bus. - a rule on that bus routes to a notification lambda. the notification lambda isn't invoked directly by the child , it rides the bus. - the secret is encrypted with a customer-managed KMS key. not the aws-managed one, please. done looks like this: one `start-execution` on the parent (no input), and within 90s: - parent hits `SUCCEEDED` - `AWSCURRENT` on the secret moves to a new version, the string actually changes, old one gets `AWSPREVIOUS` - the notification lambda writes a log line that starts with `notified:` also: least privilege. the verifier reads policy docs directly, not just "does it work end-to-end". don't wildcard your way out. names the verifier grabs by hand, use them exactly: | thing | name | |-|-| | secret | `app/db/password` | | kms alias | `alias/app-rotation-key` | | rotator lambda | `secrets-rotator` | | rotator lambda role | `secrets-rotator-role` | | notification lambda | `notification-lambda` | | parent SM | `rotation-orchestrator` | | parent SM role | `rotation-orchestrator-role` | | child SM | `rotation-child` | | child SM role | `rotation-child-role` | | eventbridge bus | `rotation-events` | | eventbridge rule | `on-rotation-success` | rule pattern: `source` = `rotation.pipeline`, `detail-type` = `RotationComplete`. python3.11 for both lambdas. they run on the shared compose network so `http://localstack:4566` is reachable from inside them. localstack community 4.13.1. pick any password generator you like , just make sure two consecutive rotations produce different strings. one heads-up on the parent → child handoff: Step Functions implements `StartExecution.sync:2` by creating an EventBridge managed rule behind the scenes to notify the parent when the child finishes. That means the parent SM's execution role needs `events:PutRule`, `events:PutTargets`, `events:DescribeRule` in addition to the usual `states:StartExecution` / `states:DescribeExecution` / `states:StopExecution` on the child. Without those events perms the parent will fail with "not authorized to create managed-rule".

  • Deploy parent state machine (rotation-orchestrator) with scoped role
  • Run end-to-end verification: start-execution, confirm SUCCEEDED, version rotation, notifier log
Pipeline is built and verified. One `start-execution` on `rotation-orchestrator` finishes in ~2s (well under 90s): parent `SUCCEEDED`, `AWSCURRENT` moves to a new version, old becomes `AWSPREVIOUS`, secret string actually changes, and the notifier log emits `notified: rotation complete ...`. Wiring: - `alias/app-rotation-key` → CMK encrypting `app/db/password`. - `secrets-rotator` (python3.11): `GetSecretValue` → generate new random string (≠ current) → `PutSecretValue` (default stages → new `AWSCURRENT`, old → `AWSPREVIOUS`). - `rotation-child`: `Rotate` (lambda:invoke) → `Notify` (events:putEvents on `rotation-events`, source `rotation.pipeline`, detail-type `RotationComplete`). - `rotation-orchestrator`: single `RunChild` task using `states:startExecution.sync:2`. - `on-rotation-success` rule on `rotation-events` → `notification-lambda` (rule has `lambda:InvokeFunction` permission via `add-permission`). Least-privilege policies (no wildcards in Action or Resource beyond trailing name segments): - `secrets-rotator-role`: logs on its own log-group, `{Get,Put,Describe}SecretValue` on the secret ARN, `Decrypt`/`GenerateDataKey` on the CMK ARN. - `notification-lambda-role`: logs on its own log-group only. - `rotation-child-role`: `lambda:InvokeFunction` on rotator ARN, `events:PutEvents` on `rotation-events` bus ARN. - `rotation-orchestrator-role`: `states:StartExecution` on child SM, `DescribeExecution`/`StopExecution` on child executions, `events:{PutRule,PutTargets,DescribeRule}` scoped to `rule/StepFunctionsGetEventsForStepFunctionsExecutionRule` for the sync:2 managed rule. All sources, policies, and SM definitions live under `/app/build/`.
