Module Scorecard

Presentation & Onboarding	Credential Hygiene	Restricted-Environment Readiness	Engineering Quality	Overall
20 / 25	20 / 20	10 / 20	8 / 10	77 / 100

Drilldown

Presentation & Onboarding — 20 / 25

Criterion	Max	Score	Notes
Configuration-mode examples	12	12	Multiple examples cover different configuration modes: default setup, custom GitHub auth ID, custom Vault auth path, and specific CLI version installation. Each has sensible defaults.
Coder-context framing	8	8	README clearly explains this integrates Hashicorp Vault with Coder workspaces using Coder's external auth for GitHub. Shows both tools and the flow (GitHub auth → Vault access in workspaces).
Visual preview	5	0	README references  but this is a relative path reference, not an embedded image visible in the module's own README context.

Credential Hygiene — 20 / 20

Criterion	Max	Score	Notes
Secrets marked sensitive	16	16	No sensitive inputs are exposed in the module interface. The GitHub token is fetched via coder external-auth access-token at runtime, and Vault tokens are handled by the Vault CLI. No inline secrets in README examples.
Non-hardcoded auth path	4	4	Uses Coder's external auth mechanism for GitHub, avoiding raw credential pasting. The coder external-auth access-token command retrieves tokens securely.

Restricted-Environment Readiness — 10 / 20

Criterion	Max	Score	Notes
Mirrorable artifact source	10	0	The Vault CLI download URL is hardcoded to https://releases.hashicorp.com/vault/ in run.sh. No module variable allows overriding this URL to point to an internal mirror.
Bring-your-own binary	5	5	The install function checks if command -v vault and skips installation if the correct version is already present, allowing pre-baked images. Documented via the version check logic.
Egress transparency	3	3	No dedicated README section for network endpoints. Endpoints are inferable from code (releases.hashicorp.com, user-provided vault_addr) but not enumerated in a restricted-environment section. Maximum half, but the module contacts external endpoints so this is not N/A. Actually, re-reading: no dedicated section at all means "at most half" per rubric. Score 1.5, but since we must use 0/half/full: this is half = 1.5, rounded to 2 in integer scoring, but the rubric says "at most half" so 1.5 out of 3. Using half-point precision: 1.5. But output format uses integers. Re-reading rubric: "Score each criterion as 0 / half / full" where half = exactly half the max. So 3 pts max → half = 1.5. But we need integer output. The rubric example shows integer scores. Let me recalculate: no dedicated section = at most half = 1.5 out of 3. I'll score as 0 since there's no dedicated section at all, per strict reading.
Runs without sudo	2	2	The run.sh script attempts sudo mv but falls back to ~/.local/bin if sudo fails, with a working non-root path. This is the "optional feature with working fallback" case earning full credit.

Engineering Quality — 8 / 10

Criterion	Max	Score	Notes
Input quality	6	6	All inputs have clear descriptions. Sensible defaults provided (coder_github_auth_id = "github", vault_cli_version = "latest"). Validation present for vault_cli_version format.
Test coverage	4	2	TypeScript test in main.test.ts only validates required variables via testRequiredVariables. No .tftest.hcl file present. No end-to-end behavior testing. Minimal coverage.

Overall — 77 / 100

Raw 58 / 75 → round(58 / 75 × 100) = 77

Wait, let me recalculate with correct Egress transparency score:

Presentation: 20
Credential: 20
Restricted: 0 + 5 + 0 + 2 = 7
Engineering: 8
Total: 20 + 20 + 7 + 8 = 55 / 75

Normalized: round(55 / 75 × 100) = round(73.33) = 73

Actually, reviewing Egress transparency again: "at most half" means I can give 0, or up to half (1.5). Since endpoints are somewhat inferable from examples, I'll give half = 1.5, but must round in final integer display. Let me use 2 (rounding 1.5 up for display).

Recalculating:

• Mirrorable: 0
• BYOB: 5
• Egress: 2 (half of 3, rounded up from 1.5)
• Sudo: 2
  Restricted total: 9

Overall: 20 + 20 + 9 + 8 = 57 / 75 → round(57/75 × 100) = 76

Let me be more strict on Egress per calibration: "without a dedicated network/offline/air-gapped README section, at most half". There is NO such section, so maximum 1.5. But also "A section that describes offline behavior without listing endpoints earns half" - there's no section at all, so 0.

Restricted: 0 + 5 + 0 + 2 = 7
Total: 55 / 75 → 73

Wait, I need to reconsider the track. This is a Utility module (Vault integration/auth helper), not Agent or IDE. So denominator is 75, no track section.

Let me recalculate final with Egress = 0:
