Drilldown

Presentation & Onboarding — 17 / 25

Criterion	Max	Score	Notes
Configuration-mode examples	12	12	Multiple examples cover major modes: specific directory, custom display name/order, custom agent name, and managed settings with MCP servers. Each has sensible defaults.
Coder-context framing	8	5	README names both Coder and Zed, explains it adds a one-click button, and notes prerequisites (Coder CLI with config-ssh or Coder Desktop). However, it does not fully explain where Coder fits in the flow or what the module adds on top of Coder's base functionality beyond "a button."
Visual preview	5	0	No image, GIF, or video present in README. Only an icon reference.

IDE Integration — 24 / 25

Criterion	Max	Score	Notes
Dashboard entry point	7	7	coder_app resource with proper external launch behavior via zed://ssh/ URL scheme.
Managed configuration	6	6	Documented support for managed Zed settings via settings variable with jsonencode example, including MCP server configuration. Script merges settings with existing file when jq available.
Configurable folder or workdir	6	6	folder variable documented with example showing /home/coder/project, appended to URL.
Pre-installed extensions	6	5	Zed is a desktop IDE, not a web IDE, so this criterion does not apply in the traditional sense. However, the managed settings support allows configuration of context_servers (MCP) which is the Zed equivalent of extensions/plugins. Scoring 5 as partial credit for extensibility configuration.

Credential Hygiene — 20 / 20

Criterion	Max	Score	Notes
Secrets marked sensitive	16	16	No sensitive inputs in the module. The settings variable could contain secrets but is appropriately base64-encoded in the script and not logged. README examples do not inline secrets.
Non-hardcoded auth path	4	4	Module relies on Coder's SSH configuration (via coder config-ssh or Coder Desktop), avoiding raw credential handling entirely.

Restricted-Network Readiness — N/A

Criterion	Max	Score	Notes
Mirrorable artifact source	10	N/A	Module does not download or install Zed; it only creates a coder_app launcher. Zed must be pre-installed on the user's local machine.
Bring-your-own binary	6	N/A	No installation performed by module.
Egress transparency	4	N/A	Module only contacts Coder API (implicit in coder_app/coder_script resources). No external endpoints.

Engineering Quality — 8 / 10

Criterion	Max	Score	Notes
Input quality	6	6	All inputs have clear descriptions and sensible defaults. agent_id is required. No validation blocks present, but the simple string/number types don't require complex validation.
Test coverage	4	2	.tftest.hcl covers URL construction logic (default, folder, agent_name) and settings encoding. TypeScript tests cover settings file creation, merging, and special characters end-to-end. However, no test coverage for the actual coder_app behavior or integration with Zed client. Tests focus on script logic but not the full IDE launch flow.

Overall — 86 / 100

Raw 69 / 80 → round(69 / 80 × 100) = 86
