Drilldown

Presentation & Onboarding — 25 / 25

Criterion	Max	Score	Notes
Configuration-mode examples	12	12	README provides three distinct examples: basic usage with default only, region whitelist filtering, and custom icons/names. Each demonstrates a different configuration mode with sensible defaults.
Coder-context framing	8	8	README clearly states "This module adds Fly.io regions to your Coder template" and references the associated Fly.io template. Names both Coder and Fly.io, explains the module creates a parameter for region selection.
Visual preview	5	5	README includes three embedded images: flyio-basic.png, flyio-filtered.png, and flyio-custom.png showing the module in action.

Credential Hygiene — N/A

Criterion	Max	Score	Notes
Secrets marked sensitive	16	N/A	Module has no credential or secret inputs; it only creates a parameter for region selection.
Non-hardcoded auth path	4	N/A	No authentication mechanism involved.

Restricted-Environment Readiness — N/A

Criterion	Max	Score	Notes
Mirrorable artifact source	10	N/A	Module downloads nothing; it only creates a Coder parameter from hardcoded region data.
Bring-your-own binary	5	N/A	No binary installation or download occurs.
Egress transparency	3	N/A	Module makes no external network calls; all region data is embedded in locals.
Runs without sudo	2	N/A	Module contains no scripts; it is pure Terraform configuration.

Engineering Quality — 10 / 10

Criterion	Max	Score	Notes
Input quality	6	6	All variables have clear descriptions (display_name, description, default, mutable, custom_names, custom_icons, regions). Sensible defaults provided (display_name = "Fly.io Region", mutable = false). The default variable includes validation logic in the parameter resource to ensure it's in the regions list when specified.
Test coverage	4	4	main.test.ts provides clear test coverage with three test cases: default output, customized default, and region filter. Tests verify business logic (default selection, region filtering).

Overall — 100 / 100

Raw 35 / 35 → round(35 / 35 × 100) = 100
