Module Scorecard

12 / 17	24 / 25	20 / 20	N/A	10 / 10	92 / 100

Drilldown

Presentation & Onboarding — 12 / 17

Criterion	Max	Score	Notes
Configuration-mode examples	12	12	README provides examples for major modes: specific directory (folder), custom display name and order, custom agent name, and managed settings including MCP servers. Each example is clear with sensible defaults.
Visual preview	5	0	No image, GIF, or video in README. Only an icon reference which does not count.

IDE Integration — 24 / 25

Criterion	Max	Score	Notes
Dashboard entry point	7	7	coder_app resource with proper zed:// URL scheme for launch behavior.
Managed configuration	6	6	Documented support for managed settings via settings variable with coder_script that writes to ~/.config/zed/settings.json. README includes MCP server configuration example.
Configurable folder or workdir	6	6	folder variable documented with example showing /home/coder/project, appended to the Zed URL.
Pre-installed extensions	6	5	N/A - Zed is a desktop IDE, not a web IDE. This criterion does not apply.

Credential Hygiene — 20 / 20

Criterion	Max	Score	Notes
Secrets marked sensitive	16	16	No sensitive inputs in this module. The settings variable contains configuration but not secrets. README examples show configuration patterns without inline secrets.
Non-hardcoded auth path	4	4	Module relies on Coder CLI (coder config-ssh) or Coder Desktop for authentication, avoiding raw key management. README explicitly documents this requirement.

Restricted-Environment Readiness — N/A

Criterion	Max	Score	Notes
Mirrorable artifact source	5	N/A	Module downloads nothing; it only creates a coder_app link and optionally writes settings via script. No artifacts to mirror.
Bring-your-own binary	10	N/A	Module does not install Zed; it assumes Zed is already installed on the user's machine (desktop application). No binary installation to skip.
Egress transparency	3	N/A	Module makes no external network calls. The coder_app URL is a protocol handler for the local Zed installation.
Runs without sudo	2	N/A	The coder_script for settings writes to user config directory (~/.config/zed) and never invokes sudo. Script runs entirely as unprivileged user. Full credit would apply if scored, but marked N/A per restricted-environment exclusion logic since no downloads occur.

Engineering Quality — 10 / 10

Criterion	Max	Score	Notes
Input quality	6	6	All inputs have clear descriptions. Defaults are sensible (empty string for optional folder, null for order/group). No validation blocks needed for the simple string/number inputs provided.
Test coverage	4	4	.tftest.hcl covers URL construction logic (default, folder, agent_name, settings encoding, empty settings). TypeScript tests in main.test.ts cover end-to-end settings file creation, JSON merging with jq, special character handling, and conditional script creation.

Overall — 92 / 100

Raw 66 / 72 → round(66 / 72 × 100) = 92

Adjusted calculation: Universal criteria applicable = 17 + 20 + 10 = 47, scored 44. IDE track = 25, scored 24. Total = 44 + 24 = 68 out of 72. Round(68/72 × 100) = 94 / 100

Recalculating precisely:

• Presentation: 12/17
• Credential Hygiene: 20/20
• Restricted-Environment: All N/A (0 points in denominator)
• Engineering Quality: 10/10
• IDE Integration: 24/25

Universal applicable: 17 + 20 + 10 = 47, scored 42
Track: 25, scored 24
Total: 42 + 24 = 66 out of 72
Round(66/72 × 100) = 92 / 100

Final recalculation with correct Runs without sudo scoring:
The module has a script (coder_script.zed_settings), so Runs without sudo applies. The script never invokes sudo and writes only to user directories. This earns full 2 points.

• Presentation: 12/17
• Credential Hygiene: 20/20
• Restricted-Environment: Mirrorable (N/A), BYOB (N/A), Egress (N/A), Sudo (2/2) = 2/2
• Engineering Quality: 10/10
• IDE Integration: 24/25

Universal: 17 + 20 + 2 + 10 = 49, scored 44
Track: 25, scored 24
Total: 44 + 24 = 68 out of 74
Round(68/74 × 100) = 92 / 100

Wait - re-reading rubric on N/A: "Runs without sudo applies whenever the module executes any script, and goes N/A only for modules with no scripts at all."

This module has a script, so Runs without sudo must be scored (not N/A). The script never uses sudo and works as unprivileged user, earning full 2 points per the rubric exception that no README mention is needed when scripts verifiably never invoke sudo.

For Restricted-Environment theme: only the download-related criteria (Mirrorable, BYOB, Egress) go N/A when nothing is downloaded. Runs without sudo stays in and scores 2/2.

Universal base: 17 + 20 + 20 + 10 = 67

• Presentation: 12/17
• Credential: 20/20
• Restricted: 2/20 (only Runs without sudo applies, scores 2/2; other 18 points N/A)
• Engineering: 10/10
  Universal scored: 12 + 20 + 2 + 10 = 44

Denominator adjustment: 67 - 18 (N/A points) = 49
Track: 24/25
Total: 44 + 24 = 68 out of 74
Round(68/74 × 100) = 92 / 100

Hmm, let me recalculate more carefully. The rubric says to exclude N/A points from denominator and normalize to 100.

Starting denominator: 92 (67 universal + 25 track)
N/A points: 18 (Mirrorable 5 + BYOB 10 + Egress 3)
Adjusted denominator: 92 - 18 = 74

Scores:

• Config examples: 12/12
• Visual: 0/5
• Secrets sensitive: 16/16
• Non-hardcoded auth: 4/4
• Runs without sudo: 2/2
• Input quality: 6/6
• Test coverage: 4/4
• Dashboard entry: 7/7
• Managed config: 6/6
• Configurable folder: 6/6
• Pre-installed extensions: 5/6 (N/A, but I incorrectly scored it - should be excluded)

Wait, Pre-installed extensions is "web IDEs only" - Zed is desktop, so this is N/A and should be excluded.

Adjusted track denominator: 25 - 6 = 19
Total denominator: 49 (universal after N/A) + 19 (track after N/A) = 68

Track scores: 7 + 6 + 6 = 19/19

Total: 44 + 19 = 63 out of 68
Round(63/68 × 100) = 93 / 100

Actually reviewing the IDE track criteria more carefully - "Pre-installed extensions (web IDEs only)" with 6 points. Since Zed is not a web IDE, these 6 points should be excluded from denominator.

Final calculation:
Universal (after N/A exclusions): 44/49
IDE track (after N/A exclusions): 19/19
Total: 63/68
Normalized: round(63/68 × 100) = 93

But wait - I need to reconsider the IDE track scoring. Let me check each:

• Dashboard entry point (7): Full - has coder_app = 7/7
• Managed configuration (6): Full - settings variable documented = 6/6
• Configurable folder (6): Full - folder variable documented = 6/6
• Pre-installed extensions (6): N/A for desktop IDE

So IDE track: 19/19 after excluding 6 N/A points.

Total: 44 (universal) + 19 (IDE) = 63 out of 68
Round(63/68 × 100) = 92.647... = 93 / 100

Let me verify once more by listing all scores:

Universal Criteria (base 67, N/A 18, denominator 49):

• Config examples: 12/12 ✓
• Visual: 0/5 ✓
• Secrets: 16/16 ✓
• Auth path: 4/4 ✓
• Mirrorable: N/A
• BYOB: N/A
• Egress: N/A
• Sudo: 2/2 ✓
• Input quality: 6/6 ✓
• Tests: 4/4 ✓
  Sum: 44/49

IDE Track (base 25, N/A 6, denominator 19):

• Dashboard: 7/7 ✓
• Managed config: 6/6 ✓
• Folder: 6/6 ✓
• Extensions: N/A
  Sum: 19/19

Total: 63/68 → 93 / 100

Actually, I realize I need to double-check the Runs without sudo score. Looking at the script in main.tf:

#!/usr/bin/env bash
set -eu
SETTINGS_B64='${local.settings_b64}'
SETTINGS_JSON="$(echo -n "$${SETTINGS_B64}" | base64 -d)"
if [ -z "$${SETTINGS_JSON}" ] || [ "$${SETTINGS_JSON}" = "{}" ]; then
  exit 0
fi
CONFIG_HOME="$${XDG_CONFIG_HOME:-$HOME/.config}"
ZED_DIR="$${CONFIG_HOME}/zed"
mkdir -p "$${ZED_DIR}"
SETTINGS_FILE="$${ZED_DIR}/settings.json"
if command -v jq >/dev/null 2>&1 && [ -s "$${SETTINGS_FILE}" ]; then
  tmpfile="$(mktemp)"
  jq -s '.[0] * .[1]' "$${SETTINGS_FILE}" <(printf '%s\n' "$${SETTINGS_JSON}") > "$${tmpfile}" && mv "$${tmpfile}" "$${SETTINGS_FILE}"
else
  printf '%s\n' "$${SETTINGS_JSON}" > "$${SETTINGS_FILE}"
fi

No sudo anywhere. Writes to user config directory. Full 2/2 confirmed.

Final answer: 93 / 100

Wait, I should recalculate one more time to be absolutely sure:

Base points: 92 (67 universal + 25 IDE)
N/A exclusions: 24 (18 from Restricted-Environment universal + 6 from IDE extensions)
Adjusted denominator: 68

Scores earned:

• Presentation: 12 (config 12, visual 0)
• Credential: 20 (secrets 16, auth 4)
• Restricted: 2 (sudo 2, others N/A)
• Engineering: 10 (inputs 6, tests 4)
• IDE: 19 (dashboard 7, config 6, folder 6, extensions N/A)

Total: 12 + 20 + 2 + 10 + 19 = 63
Denominator: 68
Score: round(63/68 × 100) = round(92.647) = 93

Hmm, but I'm seeing in my table I wrote 95/100. Let me recalculate what I actually have:

Looking at my scores again:

• Config examples: 12/12
• Visual: 0/5
• Secrets: 16/16
• Auth: 4/4
• Sudo: 2/2
• Inputs: 6/6
• Tests: 4/4
• Dashboard: 7/7
• Managed config: 6/6
• Folder: 6/6

Sum: 12+0+16+4+2+6+4+7+6+6 = 63

Denominator: 17+20+2+10+19 = 68

63/68 = 0.926... → 93/100

So the correct overall score is 93 / 100, not 95. Let me fix the table.
