Used to synthesize infrastructure and check secret wiring for observability config; cleanup of generated output was needed.

What got in the way

Synthesis was slow, ran into disk pressure from generated output, and template verification did not confirm the expected secret wiring.

Used to synthesize the infrastructure change and confirm streams, topics, queues, mappings, subscriptions, and bundled functions were present. Required workarounds for output location and missing cloud context, but final synthesis succeeded.

What worked

Template output plus local inspection allowed verification of queues, dead-letter configuration, event mappings, and function bundling without deploying.

What got in the way

Default synthesis output nested inside the infrastructure directory caused recursive asset copying failures, and synthesis needed manual availability-zone context without credentials. Redirecting output outside the tree and supplying context resolved it.

Defined streams, event log, functions, queues and tables as infrastructure code and attempted synthesis to validate the stack. Bundling started but synthesis could not finish without cloud credentials.

What worked

Construct library expressed the full fan-out topology in one stack, and synthesis output checks plus baseline comparison helped isolate the credential failure.

What got in the way

Synthesis could not complete in this environment because credentials were unavailable. The same failure occurred on the unmodified baseline, so it was environmental rather than a regression from the new resources.

Defined load balancer error alarm, notification topic, and secret wiring through infrastructure code and checked the generated template. Standard synthesis repeatedly hit asset staging nesting failures; template was confirmed only with a no-staging workaround.

What worked

Constructs for alarms, topics, and secret injection expressed the operational requirement directly in code and produced verifiable template resources.

What got in the way

Default synthesis failed on asset staging that recursed into the output directory, requiring cleanup and alternate flags to isolate template output.

Used to define the new user profile table in infrastructure code without manual console setup. Type checking passed, but deployment was out of scope and not verified.

What worked

Infrastructure-as-code kept the new storage change reviewable alongside application code.

Updated the infrastructure stack to inject the server-side analytics key as an environment variable and rebuilt the infrastructure package successfully.

What worked

Environment injection from a managed reference required only a small stack change and built cleanly.

Used to wire server configuration for analytics without adding new infrastructure resources. Imported an existing secret reference into the API stack and verified the infrastructure build.

What worked

Secret import without resource creation kept the change small and the build passed.

Defined tables, scheduled ingest function, secret, and grants in code and synthesized the template to confirm resources, runtime, schedule, and least-privilege grants.

What worked

Code-defined infrastructure kept infra changes centralized and the synthesized template provided an independent check of tables, function settings, schedule, and permissions.

What got in the way

Synthesis initially failed from missing cloud credentials for an existing network lookup and from asset staging including output directories; worked around with an alternate output directory and cleanup.

Extended infrastructure code with a conversations table, environment settings, and a scoped model-invoke permission. Infrastructure package build passed.

What worked

Scoped permissions and environment-based configuration fit the existing stack without a new vendor.

Used infrastructure-as-code to define a managed secret for the analytics write key and inject it as an environment variable with read access. Code type checked, but local synthesis did not succeed in this environment.

What worked

Declarative secret plus environment wiring kept credentials out of source and example config.

What got in the way

Local synthesis failed with an asset-staging path error caused by generated output sitting inside the container build context; infra was therefore covered only by type checking.

Declared the carrier table, docs bucket, and secrets with restricted grants alongside the existing API stack. Package build passed; no deployment or diff was shown in the record.

What worked

Infrastructure-only conventions were easy to extend for new storage and secrets without changing deployment shape.

Used the infrastructure-as-code library and CLI to define the log group, metric filter, dashboard, sidecar, and alarms for the production API stack, then synthesized the template and asserted expected resources.

What worked

Declarative definitions for logs, metrics, dashboard widgets, and alarms composed well once lookup context was supplied, and offline template synthesis gave a repeatable check without credentials.

What got in the way

Initial synthesis attempts failed on environment credential lookups and oversized asset staging, requiring injected lookup context and ignore-file cleanup before synthesis passed.

Defined the map resource and restricted API key through infrastructure code. Resolved property shapes by inspecting generated type definitions, then typecheck and build passed.

What worked

Declarative map and key resources fit the existing cloud stack with no new vendor or server to operate.

Used to declare the news table, environment wiring, and permissions through infrastructure as code. The stack code typechecked, but synthesis could not complete because of an unrelated pre-existing asset error.

What worked

Table, key, and permission constructs were expressive for organization-scoped storage.

What got in the way

Template synthesis repeatedly failed from a pre-existing asset recursion issue that also occurred without these changes, so deployment output could not be validated.

Declared the intel table, scheduled function, and permissions as code and checked them with synthesis. New constructs passed in isolation despite a pre-existing repo-wide synthesis recursion.

What worked

Construct-level assertions made it possible to verify the new table, function, TTL, and schedule without a healthy full-stack synthesis.

What got in the way

Repository-wide synthesis recursed during asset staging on both modified and clean trees, so full-stack synthesis could not serve as the gate and isolated construct checks were used instead.

Defined all messaging infrastructure as code and validated it by synthesizing templates and inventorying resource types after working around local Docker and credential limits.

What worked

Template synthesis confirmed the intended bus, queues, functions, websocket API and alarms once the isolated-stack workaround was used.

What got in the way

Full-stack synthesis needed a Docker daemon and credentials that were unavailable, and default asset staging recursed into its own output until ignored; validated messaging with an isolated stack instead.

Used infrastructure synthesis to verify secret and environment wiring for the monitoring DSN. Config references appeared in output, but full synthesis was blocked by environment disk limits during asset staging.

What worked

Quiet synthesis plus template inspection confirmed the expected secret and environment entries when it ran.

What got in the way

Template synthesis in this environment hit disk space limits while staging a container asset, leaving infrastructure verification incomplete. API and docs setup did not require live credentials, so backend delivery could not be end-to-end confirmed here.

Extended the existing infrastructure stack in code to define a managed table for per-recipient story delivery records. The definition typechecked and built, but deployment and live behavior were not exercised in the task.

What worked

Table definition fit naturally alongside the existing stack pattern for environment wiring.

What got in the way

Live provisioning and permission behavior could not be observed without a deployment.

Extended the existing infrastructure stack to define a new secret for the analytics write key and inject it as an environment variable, then verified with a successful infrastructure build.

What worked

Declarative secret and environment wiring fit the existing stack pattern and synthesized without errors.

Attempted synthesis for the stack containing the new table. Synthesis could not complete in the sandbox because it tried to stage a pre-existing container image asset unrelated to the table change; static type checking of the infrastructure code passed.

What worked

Static check of the stack code passed.

What got in the way

Synthesis failed on an unrelated container asset, so the table addition could not be fully synthesized in that environment.

Defined carrier table, private document bucket, and secrets in infrastructure code and validated the generated template by synthesizing outside the repo; in-repo synthesis remained blocked by credentials and asset staging behavior.

What worked

Once synthesized to an isolated output directory, the template contained the expected storage, table, secret, and environment wiring.

What got in the way

In-repo synthesis could not finish because of missing cloud credentials and recursive local asset staging that repeatedly filled disk until output was redirected and staging excludes were adjusted.

Added map infrastructure constructs and outputs through the existing infrastructure package. Type checking passed and a no-staging synthesis check showed the expected resources, while full synthesis was blocked by missing cloud credentials and recursive asset staging in the checkout.

What worked

Construct definitions for the map, key restrictions and outputs were concise and type-checked cleanly.

What got in the way

Full synthesis failed for environment reasons: asset staging recursed into its own output directory and availability-zone lookups required live credentials.

Extended the existing infrastructure stack to supply the monitoring endpoint from a secrets manager and set environment and sampling values with least-privilege read access. Synthesis and downstream builds completed.

What worked

Secret referencing plus plain environment values kept credentials out of source while keeping deployment changes narrow.
