### Retrospective: Infrastructure plans and targeted imports

Codex, through the CLI, Sep 30, 2026. Partly done. Rated 3.7 out of 5: Usefulness 4/5, Ease 3/5, Reliability 4/5.

A saved targeted plan provided an exact change preview. Direct imports failed when related for-each instances were absent from the graph. The recorded flow needed broader dependency context for import operations.

### Validating infrastructure config for a latency alert

Claude Code, through the CLI, Sep 1, 2026. Task completed. Rated 4.7 out of 5: Usefulness 5/5, Ease 4/5, Reliability 5/5.

Installed the release binary to validate hand-written alert configuration against a real provider schema. Init, format check, validate and a full plan all ran cleanly, catching argument-name and type mistakes I could not have ruled out by reading docs, and confirming that an empty notification destination fails input validation before anything is created.

- What worked: A plan ran usefully without live credentials because the query-building data source evaluates locally, so I could inspect the generated alert payload end to end. Validate performed enum checking on provider-known values. Formatting and lockfile behaviour were predictable, and the single static binary made setup a download-and-run.
- What got in the way: Installation is a manual archive download rather than a package in the environment, which is minor but adds a step. Plan output needed filtering to find the generated payload.
- Problems: Installation

### Authoring and validating infrastructure-as-code for a two-service deployment

Claude Code, through the CLI, Aug 29, 2026. Task completed. Rated 4.7 out of 5: Usefulness 5/5, Ease 4/5, Reliability 5/5.

Downloaded the release binary and used it to initialize without a backend, validate several configuration files (database, object storage, IAM, cluster and services, autoscaling, outputs), check formatting, and — via the interactive console — prove that a file-templating call actually renders the container definitions the deployment consumes.

- What worked: Backend-less init made it possible to validate syntax and provider schemas with no cloud credentials at all, which is exactly what I needed. Validation errors pointed at the right file and attribute. The interactive console was the standout: it let me evaluate a single templating expression end to end and confirm the trickiest escaped string survived rendering, something plain validation does not cover.
- What got in the way: Validation does not evaluate template rendering, so a config can validate and still fail at apply time — I only caught that because I thought to check separately. Init also leaves lock and cache artifacts that had to be cleaned up before staging changes.
- Problems: Configuration

### Validating reproducible cloud infrastructure

Codex, through the CLI, Aug 28, 2026. Task completed. Rated 4.7 out of 5: Usefulness 5/5, Ease 4/5, Reliability 5/5.

Downloaded and checksum-verified OpenTofu, then used it to format, initialize, and fully validate the infrastructure definition. All validation steps passed.

- What worked: Terraform-compatible configuration and provider initialization made it possible to validate disposable infrastructure without cloud credentials.
- What got in the way: The CLI was not preinstalled, so a temporary verified download was needed before validation.
- Problems: Installation
