PR Review: ENG-1418 — Add eco-first skills and commands

• Read changed files
• Review skill definitions (eco-design, eco-review)
• Review commands (eco-design, eco-refresh, eco-review)
• Review supporting data and config changes
• Post final review

Overview

This PR adds two substantial skill definitions (eco-design and eco-review) and three commands (/eco-design, /eco-review, /eco-refresh) to the carbonlog plugin, along with a carbon intensity reference data file. The content is well-researched and the patterns are clearly motivated. A few issues worth addressing below.

Issues

1. plugin.json version not bumped

plugins/carbonlog/.claude-plugin/plugin.json still shows "version": "3.0.0", but this is a significant feature addition. If the marketplace uses semver for anything, this should be bumped to 3.1.0. Fix this →

2. eco-review skill references a placeholder URL

In plugins/carbonlog/commands/eco-refresh.md line 12:

3. Any updates to the eco-first-patterns repo (placeholder: https://github.com/jm-cnaught/eco-first-patterns)

The inline comment "placeholder" suggests this URL isn't real yet. Either replace it with the real URL or remove the web search step for this source until it exists — otherwise Claude will search a non-existent repo and produce confusing output. Fix this →

3. eco-design skill footer links to eco-first, but the plugin is named carbonlog

In plugins/carbonlog/skills/eco-design/SKILL.md line 191:

*Generated by [eco-first](https://github.com/CNaught-Inc/eco-first)*

Same in eco-review/SKILL.md line 101. The plugin is named carbonlog and the repo appears to be claude-code-plugins. Either the link target is wrong or this is intentional branding — if intentional, the URL should resolve correctly. Fix this →

4. allowed-tools is empty on all three commands

All three command files set allowed-tools: []. The eco-refresh command explicitly instructs Claude to do web searches, but without WebSearch in allowed-tools, users will be prompted for permission on every run. Eco-review also does filesystem scanning. Consider pre-authorizing the tools each command needs:

• eco-refresh.md: allowed-tools: [WebSearch, WebFetch]
• eco-review.md: allowed-tools: [Read, Glob, Grep]
• eco-design.md: allowed-tools: [Read] (for .eco-ignore check)

Fix this →

Observations / Minor

• The eco-design SKILL.md (206 lines) and eco-review SKILL.md (569 lines) are well-structured with clear pattern IDs, effort labels, risk notes, and citations. The segmentation into "Sustainability-Specific" vs "Engineering Co-Benefits" is a good UX choice.
• The carbon intensity data in carbon-intensity.md matches the Google Cloud 2024 source and is clearly attributed with a disclaimer about grid reality vs. renewable credits. Good.
• The rename-team.md and uninstall.md tweaks (adding "with multiple choices" to the AskUserQuestion note) are minor clarifications and look correct.
• Marketplace description update accurately reflects the new capabilities.
• The eco-review skill's "Worth Checking" section and .eco-ignore suppression file support are thoughtful additions for reducing false-positive noise.

Summary

3 issues to address before merging: version bump, placeholder URL in eco-refresh, and empty allowed-tools on the commands. The core skill content is solid.
