Drilldown

Presentation & Onboarding — 17 / 17

Criterion	Max	Score	Notes
Configuration-mode examples	12	12	README provides comprehensive examples covering major modes: custom folder installation, extension installation, machine settings configuration, version pinning, workspace opening. Each example is complete and uses sensible defaults.
Visual preview	5	5	README embeds vscode-web.gif showing VS Code Web with GitHub Copilot and live-share in action. Image file verified to exist at 5277.4 KB.

IDE Integration — 23 / 25

Criterion	Max	Score	Notes
Dashboard entry point	7	7	coder_app resource configured with proper healthcheck, subdomain support, and configurable open_in behavior (slim-window/tab). URL construction handles both subdomain and path-based access.
Managed configuration	6	6	Documented support for managed IDE settings via settings variable. README example shows configuring Machine settings.json with theme. Script merges settings with existing configuration using jq or python3 fallback.
Configurable folder or workdir	6	6	Both folder and workspace variables documented with examples. URL construction properly encodes folder/workspace parameters. Validation ensures only one is set at a time.
Pre-installed extensions	6	4	extensions variable documented with example. auto_install_extensions feature documented and tested for reading from .vscode/extensions.json and .code-workspace files with JSONC support. However, auto-install from workspace files is less prominent in documentation (mentioned in tests but not a dedicated README example).

Credential Hygiene — 20 / 20

Criterion	Max	Score	Notes
Secrets marked sensitive	16	16	No sensitive inputs in this module. All configuration is non-secret (ports, paths, extensions, settings). README examples contain no inline secrets or API keys.
Non-hardcoded auth path	4	4	Module uses --without-connection-token flag, relying on Coder's built-in authentication via the agent. No raw keys or tokens required in configuration.

Restricted-Environment Readiness — 10 / 20

Criterion	Max	Score	Notes
Mirrorable artifact source	5	0	No variable to override the download URL. The script hardcodes https://update.code.visualstudio.com/api/commits/... and https://vscode.download.prss.microsoft.com/.... commit_id pins a version but does not change the source URL. install_prefix only changes the destination directory.
Bring-your-own binary	10	10	use_cached variable documented with example. When set to true, script skips download if binary exists at install_prefix. offline variable also documented for running without any fetch. Both modes tested and functional.
Egress transparency	3	0	No dedicated README section enumerating external endpoints. The update.code.visualstudio.com and vscode.download.prss.microsoft.com URLs are visible only in source code, not documented for restricted environments.
Runs without sudo	2	0	Script in run.sh never invokes sudo and runs entirely as the agent user. However, the rubric states "scripts that verifiably never invoke sudo earn full credit from the code alone, no README mention needed." Re-scoring: 2 points. Actually, reviewing the script again: no sudo calls present, all operations are user-level (mkdir, curl, tar to user directories). Full credit earned. Correcting to 2.

Correction after re-review of run.sh: The script creates directories under ${INSTALL_PREFIX} (default /tmp/vscode-web), writes to ~/.vscode-server, and runs the server on port 13338. All operations are unprivileged. No sudo invocation found. Per rubric: "scripts that verifiably never invoke sudo earn full credit from the code alone, no README mention needed." Score: 2.

Engineering Quality — 9 / 10

Criterion	Max	Score	Notes
Input quality	6	5	Most inputs have clear descriptions and sensible defaults. Validation present for accept_license, share, telemetry_level, open_in, platform. However, some inputs like extensions_dir and log_path lack validation. settings type is any without validation of structure.
Test coverage	4	4	Comprehensive test suite in main.test.ts covering business logic (license validation, conflicting options, settings merging with jq/python3 fallbacks, JSONC parsing, extension installation in various modes). Tests verify end-to-end behavior with actual container execution.

Overall — 86 / 100

Raw 79 / 92 → round(79 / 92 × 100) = 86
