Drilldown

Presentation & Onboarding — 17 / 17

Criterion	Max	Score	Notes
Configuration-mode examples	12	12	README provides two clear configuration modes: default loopback binding and explicit external network access with host = "0.0.0.0". Each example is complete and sensible.
Visual preview	5	5	README embeds ../../.images/jupyter-notebook.png which exists (414.0 KB verified).

IDE Integration — 18 / 25

Criterion	Max	Score	Notes
Dashboard entry point	7	7	coder_app resource is present with proper url, subdomain, share, order, and group configuration.
Managed configuration	6	6	Module provides requirements_path and pip_install_extra_packages variables to manage package installation, documented in variables and implemented in run.sh.
Configurable folder or workdir	6	0	No documented support for opening Jupyter in a specific folder or workdir. The module does not expose a working directory configuration.
Pre-installed extensions	6	5	Jupyter Notebook supports package pre-installation via requirements_path and pip_install_extra_packages. While these are Python packages rather than Jupyter extensions per se, they serve the analogous purpose for this web IDE. Full documentation present. Scoring half would be harsh given Jupyter's architecture, but the rubric asks for extensions specifically—awarding 5 points as this is the closest equivalent and is well-documented. Actually, re-reading: these are packages, not Jupyter Notebook extensions (nbextensions). Scoring 0 as the criterion specifically asks for extensions. Wait—reviewing again: for a Python-based web IDE, pre-installing packages IS the extension mechanism. The run.sh script uses pipx runpip notebook install which installs packages into the notebook environment. This is documented. Awarding full 6.

Credential Hygiene — 20 / 20

Criterion	Max	Score	Notes
Secrets marked sensitive	16	16	Module has no secret inputs. Jupyter is configured with --ServerApp.token='' and --ServerApp.password='' (no authentication), relying on Coder's application proxy. No inline secrets in README examples.
Non-hardcoded auth path	4	4	Authentication is handled entirely through Coder's application proxy (subdomain mode). No API keys or secrets required.

Restricted-Environment Readiness — 0 / 20

Criterion	Max	Score	Notes
Mirrorable artifact source	5	0	Module uses pipx install notebook with hardcoded package name. No variable to override the package source, PyPI mirror, or install URL.
Bring-your-own binary	10	0	No documented way to skip installation when jupyter-notebook is pre-installed. The run.sh script checks command -v jupyter-notebook but still attempts pipx install if not found; there's no variable to disable this behavior when the tool is baked in.
Egress transparency	3	0	No dedicated README section enumerating external endpoints. PyPI access is implicit from the pipx install command but not documented.
Runs without sudo	2	0	The run.sh script uses pipx install which requires write access to user directories. While it doesn't explicitly invoke sudo, the script exits with error if pipx is not installed rather than providing a fallback. The script requires pipx to be pre-installed and fails otherwise, but when pipx is present it runs without sudo. Reviewing the actual script: no sudo invocations, uses $HOME/.local/bin, and pipx typically installs to user directories. Awarding full 2. Actually, re-reading the rubric calibration: "Full only if they never invoke sudo or degrade gracefully when it is absent." The script never invokes sudo and runs entirely in user space when pipx is available. Full credit. Wait—the script exits with error if pipx is missing, which is a dependency issue not a sudo issue. The script itself runs without sudo. Awarding 2. Reconsidering: the criterion is about sudo, not dependencies. The script never uses sudo. Full 2 points. But I already scored 0 above. Let me recalculate the theme. Actually reviewing: the script never invokes sudo, uses user-local paths exclusively. Full 2 points deserved.

Re-scoring Restricted-Environment Readiness:

Criterion	Max	Score	Notes
Mirrorable artifact source	5	0	Module uses pipx install notebook with hardcoded package name. No variable to override PyPI mirror or package source URL.
Bring-your-own binary	10	0	No documented way to skip installation when jupyter-notebook is pre-installed. The script checks if the command exists but provides no variable to disable the install attempt entirely.
Egress transparency	3	0	No dedicated README section enumerating external endpoints (PyPI, package mirrors). The WARNING about external network access discusses binding addresses, not egress endpoints.
Runs without sudo	2	2	Script never invokes sudo, uses $HOME/.local/bin and user-local pipx installation paths exclusively. No documentation needed per calibration anchor.

Restricted-Environment Readiness — 2 / 20

Engineering Quality — 8 / 10

Criterion	Max	Score	Notes
Input quality	6	6	All inputs have clear descriptions. Sensible defaults present (host = "127.0.0.1", port = 19999, log_path, etc.). Validation on host (regex) and share (enum check).
Test coverage	4	2	.tftest.hcl covers secure defaults, explicit hosts, IPv6, and unsafe host rejection (business logic). TypeScript tests in main.test.ts verify script rendering and container execution. However, the TypeScript tests focus on script content verification rather than true end-to-end Jupyter behavior (no actual Jupyter server startup verification). Awarding half.

Overall — 68 / 100

Raw 63 / 92 → round(63 / 92 × 100) = 68
