Carbon Decision Memos

Category: Dev Tools  ·  Sub-category: scaffolders  ·  Last updated:
Write structured decision memos for carbon project choices — registry selection, methodology selection, measurement architecture tradeoffs (estimation vs. in-situ), buyer/offtake structure, and other consequential project decisions where the tradeoffs need to be documented before locking in. Use whenever the user is weighing a carbon-project-specific decision and wants it written up formally, or says things like "help me think through whether to use X or Y methodology/registry," "document why we chose," or "write up the tradeoffs." Trigger proactively when other skills in this pack (pdd-generator, carbon-project-timeline) flag an unresolved decision blocking progress.

From the source SKILL.md

Writes the decision memo that should exist before a consequential, hard-to-reverse carbon project choice gets locked in. Methodology selection, registry choice, and measurement architecture decisions are expensive to reverse once a PDD is in validation, so the memo exists to force the tradeoffs onto paper before the team commits, not to retroactively justify a decision already made.

What this skill does

Carbon Decision Memos is a community-contributed Claude Code skill in the scaffolders sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/carbon-decision-memos/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever the user is weighing a carbon-project-specific decision and wants it written up formally, or says things like "help me think through whether to use X or Y methodology/registry," "document why we chose," or "write up the tradeoffs." Trigger proactively when other skills in this pack (pdd-generator, carbon-project-timeline) flag an unresolved decision blocking progress.

Who uses this skill

The Carbon Decision Memos Claude Code skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 154,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
