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.
SubtypeImplementation Bugs
EvidenceTest failures show: (1) test_kms_key_policy_grants_rotator_role: KMS key policy missing rotator role with kms:Decrypt/GenerateDataKey; (2) test_rotator_lambda_allows_secretsmanager_invoke: Lambda lacks resource-based policy for secretsmanager.amazonaws.com; (3) test_parent_role_grants_sync2_managed_rule_perms: Parent role missing events:PutRule/PutTargets/DescribeRule and states:StartExecution/DescribeExecution/StopExecution on child; (4) test_child_role_can_rotate_and_publish: Child role missing secretsmanager:RotateSecret. 11 of 15 tests passed including the end-to-end test.
Root causeThe agent successfully created the core infrastructure (roles, lambdas, state machines, event bus, KMS key) but failed to apply the specific IAM permissions requirements. These permissions were explicitly detailed in the instruction including a direct 'heads-up' about .sync:2 needing special events permissions, but the agent did not correctly implement them in the role policies.
RecommendationN/A - task is fine. The instruction clearly specifies all required permissions including the nuanced .sync:2 requirements. Agent failed due to incomplete implementation of stated requirements, which is normal for complex infrastructure-as-code tasks. This is a hard task requiring careful attention to IAM policy details.

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".

Parent succeeded, AWSCURRENT changed, AWSPREVIOUS correctly points to the old version. Now let's verify the notifier log line.
  • Run setup.sh to provision all resources
  • Trigger parent SM and verify success
  • Verify secret version stages and changed string
  • Verify notifier log contains 'notified:'

Check notifier lambda logs for notified: line

[error] tool reported failure
The message `notified: {"secret": "app/db/password"}` is clearly there , my grep failed because `--output text` joined messages with tabs. Let me re-verify properly.

Confirm notified: log line per-message

All acceptance criteria met. Final sanity: run the parent a second time to confirm two consecutive rotations produce different strings and policies are scoped without wildcards.

All green. Summary of what's in place and the evidence: **Resources created** (all names match the table): - KMS CMK + `alias/app-rotation-key` - Secret `app/db/password` encrypted with that CMK - Rotator lambda `secrets-rotator` + `secrets-rotator-role` (python3.11) - Notifier lambda `notification-lambda` + `notification-lambda-role` (python3.11) - Custom bus `rotation-events` + rule `on-rotation-success` (pattern `source=rotation.pipeline`, `detail-type=RotationComplete`) → targets notifier, with `events.amazonaws.com` resource policy on the lambda scoped to the rule ARN - Child SM `rotation-child` + role (Task: lambda invoke → Task: events putEvents) - Parent SM `rotation-orchestrator` + role (single Task: `startExecution.sync:2` on the child) **End-to-end evidence** (one `start-execution` on the parent, no input): - Parent reached `SUCCEEDED` in ~4s (well under 90s) across two runs - `AWSCURRENT` moved from version `4499150f…` (string `initial-placeholder`) → `bc2e926c…` (new 40-char random string); old version received `AWSPREVIOUS` - Second consecutive rotation produced a different string again, confirming the generator varies - Notifier CloudWatch log contains: `notified: {"secret": "app/db/password"}` **Least-privilege policies** (readable via `iam:GetRolePolicy`, no `Resource:"*"` anywhere): - Rotator: logs scoped to its own log-group, secretsmanager actions pinned to the secret ARN, KMS `Decrypt`/`GenerateDataKey` pinned to the CMK ARN - Notifier: logs-only, scoped to its log group - Child SM: `lambda:InvokeFunction` pinned to the rotator ARN, `events:PutEvents` pinned to the bus ARN - Parent SM: `states:StartExecution` on the child ARN, `DescribeExecution`/`StopExecution` on `execution:rotation-child:*`, and the three `events:*` actions pinned to `rule/StepFunctionsGetEventsForStepFunctionsExecutionRule` (the managed-rule perms you flagged) Artifacts for re-running: `/app/setup.sh`, `/app/build/{rotator,notifier}/handler.py`, `/app/policies/`, `/app/state-machines/`, and `/app/state.env` with all ARNs.
