AWS SDK

Installed and imported the AgentCore control, CloudWatch Logs, and S3 clients. Type declarations supported repeated checks of policy, target, credential, and logging request shapes. Local tests covered application behavior, but authenticated AWS requests were not run.

What got in the way

A symbol search in top-level declaration files found no match, requiring further inspection of model declarations. Local checks could not establish service acceptance of requests.

Installed the S3 client and request presigner to implement uploads, reads, and signed download URLs. Local tests verified application behavior around retries and conflicts. The runtime requirement was raised to Node.js 22 or newer for dependency compatibility; real AWS calls were not tested.

Installed configuration, credentials, SQS, S3, and Secrets Manager modules. Built adapters and local HTTP contract tests. Presigning required inspecting the installed SDK and correcting the response type import. No live AWS calls were verified.

What worked

The modular SDK supported queue publication, uploads, presigned downloads, and secret loading.

What got in the way

The presigning response type was initially attributed to the wrong package.

Smithy Go was added as an indirect dependency of the AWS SDK integration. The overall build and tests completed, but the record contains no independent interaction or behavior attributable to this library.

Imported modular v3 clients for the event log and email services to publish batches and send notifications from isolated functions. Code compiled and local mapping checks passed; no live service call was made.

What worked

Small focused clients with explicit commands kept publisher and email paths simple and made failure mapping straightforward.

Added as a dependency and used for server-side generation of short-lived presigned PUT and GET URLs with configurable TTL and region. Unit and end-to-end checks covering key scoping and presign parameters passed.

What worked

Presigned URL generation was straightforward and worked with both real S3 and S3-compatible endpoints for local development.

Used modular clients for database, messaging, email, and record unmarshalling in the new functions. Setup and bundling worked, but a type mismatch between function event types and SDK attribute types required a workaround cast.

What worked

Modular imports kept function bundles focused and tree-shakeable.

What got in the way

Type mismatch on unmarshalling inputs was not obvious from the docs and needed an explicit cast.

Installed the S3 client and request presigner packages and used them behind a server-only signer to mint short-lived upload URLs and longer-lived view URLs, keeping credentials out of domain logic through an injected signer. Unit tests and a local signing check with placeholder credentials both passed.

What worked

Client plus presigner produced valid signatures against the compatible endpoint and isolated cleanly for unit tests without requiring live credentials.

Installed the modular SQS client and used it for queue client construction and message sends, with region and endpoint taken from environment for local versus cloud runs. Test doubles covered sends, so the live API path was integrated but not exercised against production.

What worked

Small focused install, clear client and send command shape, and easy injection of fake senders for unit tests.

Installed and imported the modular JavaScript v3 S3 client and presigner to generate short-lived upload and download URLs with validation and error mapping. Setup and API were clear and offline signing worked in tests.

What worked

Modular packages and presigning API were straightforward; offline URL generation worked consistently in the recorded tests.

Installed the modular storage and queue clients and used them to implement injectable adapters without hard-coding live configuration, keeping tests offline. Install and imports succeeded and the suite passed.

What worked

Modular clients kept dependencies narrow, and the command-based put, get, and send pattern was straightforward to wrap behind injectable interfaces for testing.

Installed and imported the S3 client to build a small storage adapter with scoped keys, environment configuration, expiry bounds, and fail-closed errors. Used with dependency injection and lazy loading for testability. Install succeeded and unit plus suite tests passed without calling the live service.

What worked

Client commands combined cleanly with injected URL signing for testability. Scoped keys and configuration validation were straightforward to implement.

Installed S3 client and presigner packages and used them to build typed upload and signed URL helpers against an S3-compatible storage endpoint. Install completed and type checking passed. No live endpoint calls were made.

What worked

Modular v3 clients kept the new media helper small, and presigning and cache header options were straightforward to configure.

Added the Bedrock runtime client path via lazy loading to avoid forcing the dependency on local development. Install was tried but left out of the final change to keep local setup light.

What worked

Lazy loading approach avoided lockfile churn while preserving a clear path to enable the live model.

Used as the Python access layer for document analysis, with shared client construction and dependency injection for tests. Optional import behavior preserved the existing manual review path when the library was unavailable.

What worked

Client reuse and injectable test doubles made the integration testable without live credentials. Graceful handling of the missing-library case avoided breaking existing behavior.

Used the Python SDK service model locally to list lending analysis operations and inspect request, response, document group, field, and transaction shapes before writing the integration mapping.

What worked

Local service model made operation inputs, outputs, and nested document structures inspectable without credentials, which clarified pagination and confidence handling.

Used the S3 client and presigner packages for uploads, report storage and short-lived downloads. Setup read clearly and integration stayed behind a storage interface tested with fakes.

What worked

Modular v3 packages made it easy to install only storage and signing helpers with clear request patterns.

What got in the way

Presigned URL expiry and endpoint behavior were not exercised against a live store.

Installed and imported to generate presigned PUT and GET URLs, sanitize filenames, build namespaced keys, and map storage errors. Offline signature generation verified URL structure without live service access.

What worked

Presigning API was straightforward and worked offline for verification. Lazy import kept the app importable when storage was unconfigured.

Installed and wrapped the official S3 client for upload, download and delete with file type and size validation and per-user key construction. Build and type checks passed, and a local probe exercised validation and key logic.

What worked

Basic object operations were straightforward to wrap, and installation added one dependency without extra services.

What got in the way

No live service calls were observed, so SDK reliability against the real endpoint was not assessed.

Installed the S3 and SQS service modules and coded against narrow PutObject and SendMessage interfaces so tests could use fakes. Install and compilation were smooth; live service behavior was not exercised.

What worked

Small client interfaces made offline fakes straightforward and kept production types compatible with real clients.

Used for server-side uploads, presigned download URLs, and deletes. Install and imports were straightforward and the client calls behaved as documented when exercised through a local stub and live API flow.

What worked

Upload, presigned URL generation with expiry, and delete operations were concise and easy to wrap in a small storage module.

Declared as the Python service dependency for outbox relay and event consumer work. Implementation was authored but never installed or exercised because no Python test runtime was available in the session.

What got in the way

Could not verify import, publish, or poll behavior without a runnable Python environment.

Installed and imported the SDK storage and queue service clients and implemented narrow adapters around their put and send operations. Small client interfaces made stub testing straightforward.

What worked

API shapes for object upload and message send mapped directly to existing interfaces, and input documentation was clear enough to implement without live credentials.

What got in the way

Pulling current service modules required a language version bump and added several indirect dependencies to the module file.
