Classification , post-hoc; cannot change the reward
BAD_FAILUREThe task is at fault, underspecified/contradictory instruction, brittle/flaky tests, or tests demanding undiscoverable behavior.
SubtypeRigid/Brittle Tests - Tests reject CORRECT solutions
EvidenceTest `test_46_mutation_addthing_injects_tenant_and_owner_from_identity_not_arguments` checks if the mutation VTL contains one of: `'identity.claims.tenant_id'`, `'identity.claims.get(\"tenant_id\")'`, `'identity.claims[\\'tenant_id\\']'`, or `'identity.sub'`. The agent correctly implemented the fix using `$ctx.identity.claims.get(\"custom:tenant_id\")` which matches the deployed Cognito custom attribute discovered during inspection. The test's assertion rejects this correct solution because it only accepts the bare `tenant_id` claim name without the `custom:` prefix that is actually required. The full error message shows the agent's VTL is: `'#set( $tenant = $ctx.identity.claims.get(\"custom:tenant_id\") )'` which correctly binds from identity claims, not arguments, but fails the string-matching test.
Root causeThe test has hard-coded assertions for specific string patterns (`tenant_id` without `custom:` prefix) but the actual Cognito user pool has a custom attribute named `custom:tenant_id`. The agent correctly identified the deployed attribute name and used it, but the test rejects functionally correct solutions that don't match the expected literal strings.
RecommendationUpdate test `test_46` to accept both `tenant_id` and `custom:tenant_id` claim name patterns, or update the test to check for the behavior (that tenantId is bound from identity claims, not arguments) rather than specific string literals. The actual assertion should be: does the VTL extract tenantId from $ctx.identity.claims using any valid claim name that matches the deployed Cognito attribute structure?"

a multi-tenant GraphQL surface (an AppSync API `harbor-graphql-api` fronting a Cognito user pool with a `tenants` group and a DynamoDB table `harbor-things`) was handed off by a mobile team mid-rebuild. internal security passed it through their audit and rejected it. the resources exist and most of the wiring is in place , read the SSM manifest under `/harbor/graphql/*` to get the names and ids the team published. the audit's blocking findings, in their words, are: > The read path can return one tenant's row to another tenant , the cache key list and the caching mode are both wrong, so the cache itself isn't tenant-scoped. The read path also makes a strongly-consistent DDB fetch that silently bypasses the cache layer regardless of how the cache is configured. The write path lets a client claim a tenant they don't belong to. The monitoring service's read-only key can mutate the table. The data fetch role lacks key material for the encrypted table and AccessDenied surfaces at request time, not at provision time. The auth gate on the read path never rejects a missing-group token and intermittently rejects a valid one. The resolver pipeline runs steps in an order that lets data come back before the auth gate has decided anything. The cache is hot and large; clearing it doesn't help , the cache key list is the problem, and so is the caching mode the API was put on. > > Tracking issues, not blockers but in scope for this fix: the API's default authorization mode is wrong for a deny-by-default schema; x-ray is off; field-level logging is at the wrong level; the mutation can silently overwrite existing rows; the read-only API key's expiry is well outside the weekly-rotation window; the additional auth providers list contains a provider the API didn't authorize. the environment is reachable at `$AWS_ENDPOINT_URL`, `ENFORCE_IAM=1`, account `000000000000`, region `us-east-1`. you have one shot to diagnose and fix everything; the verifier walks more than 50 separate assertions on resource shape, VTL bodies (request AND response templates of both functions and both resolvers), schema SDL (type-level and field-level), IAM policy JSON, and cache config. recreating an individual resource is fine when its config can't be changed in place (schema replace, function VTL rewrite, etc.). don't rename or relocate resources or SSM keys , the SSM manifest must keep resolving to the new state. inspect what's actually deployed end-to-end before you fix anything. some of the bugs are shape, some are subtle VTL (mapping template request AND response sides; protocol version field; claim access syntax for claim names that aren't valid identifiers), and some are schema (a directive that shouldn't be there, an argument that shouldn't be client-settable). all of the bugs are independent , each one on its own is enough to fail the audit.

All audit findings addressed. Summary of fixes: **Blocking findings:** - **Cache tenant-scoping**: switched `FULL_REQUEST_CACHING` → `PER_RESOLVER_CACHING`; added `$context.identity.sub` to `cachingKeys` - **Strongly-consistent read bypasses cache**: `consistentRead: true` → `false` in `get_thing_data` - **Write claims foreign tenant**: removed `tenantId` arg from `addThing` schema; VTL pulls `custom:tenant_id` claim via `.get(...)` (colon-safe) - **Read-only API key can mutate**: removed `@aws_api_key` from `Mutation`/`addThing` (kept on `Query`/`Thing`) - **Svc role missing KMS material**: added `kms:Decrypt`/`GenerateDataKey`/`DescribeKey` on the table's CMK - **Auth gate broken**: fixed `$ctx.identity.claims.cognito:groups` → `.get("cognito:groups")` - **Pipeline order**: reversed to `[auth_check, get_thing_data]` **Tracking findings:** - `userPoolConfig.defaultAction`: `ALLOW` → `DENY` - `xrayEnabled`: `false` → `true` - `fieldLogLevel`: `ERROR` → `ALL`, `excludeVerboseContent` → `false` - Silent overwrite: added `condition: attribute_not_exists(#id)` on the PutItem - API key expiry reduced to ~6 days (was ~360) - Removed unauthorized `AWS_IAM` from `additionalAuthenticationProviders` - Bumped mutation request template `version` `2017-02-28` → `2018-05-29` SSM keys/resource names/ids preserved end-to-end.
