Drilldown

Presentation & Onboarding — 17 / 17

Criterion	Max	Score	Notes
Configuration-mode examples	12	12	Three documented examples cover the major modes: basic default selection (default = "atl"), region whitelist (regions = ["ams", "arn", "atl"]), and custom icons/names via custom_icons/custom_names maps. Each uses sensible defaults and is clearly explained.
Visual preview	5	5	README embeds three verified images: flyio-basic.png (46.8 KB), flyio-filtered.png (38.1 KB), flyio-custom.png (55.7 KB), each illustrating a distinct configuration mode.

Credential Hygiene — 16 / 20

Criterion	Max	Score	Notes
Secrets marked sensitive	16	16	The module defines no sensitive inputs (all variables are region names, display strings, booleans, and maps). No sensitive = true is needed. README examples contain no inline secrets or placeholder keys.
Non-hardcoded auth path	4	0	The module involves no authentication mechanism whatsoever (no API keys, tokens, or provider credentials). No auth path is documented. Criterion is not marked "if applicable," so absent support scores zero.

Restricted-Environment Readiness — N/A

All four criteria are excluded: the module downloads nothing, installs nothing, and contains no scripts. It solely declares a coder_parameter data source in HCL. Per rubric, download-related criteria go N/A when the module downloads or installs nothing of its own; "Runs without sudo" goes N/A for modules with no scripts at all.

Criterion	Max	Score	Notes
Mirrorable artifact source	5	N/A	Module downloads nothing.
Bring-your-own binary	10	N/A	Module installs nothing.
Egress transparency	3	N/A	Module contacts no external endpoints.
Runs without sudo	2	N/A	Module contains no scripts.

Engineering Quality — 5 / 10

Criterion	Max	Score	Notes
Input quality	6	3	All seven variables have clear description fields and sensible default values (e.g., mutable = false, regions = []). Types are declared. However, no validation blocks are present; a default variable could validate against known region codes, and regions could validate entries, which would be appropriate for a region selector.
Test coverage	4	2	main.test.ts provides three end-to-end cases via runTerraformApply (empty output, custom default, region filter) plus testRequiredVariables. No .tftest.hcl file is present to cover business logic at the Terraform level. Coverage is functional but minimal.

Overall — 81 / 100

Raw 38 / 47 → round(38 / 47 × 100) = 81

Track: Utility (parameter/helper module; no Agent or IDE track applied)
