The codebase shows you what exists. Myco shows you why it exists — why this approach was chosen over alternatives, what broke along the way, what's non-obvious. When you're wondering why something is the way it is, or whether something was already tried, Myco has the answers.
Myco is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/myco/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when making design decisions, debugging non-obvious issues, encountering gotchas, wondering why code is structured a certain way, or when you need context about prior work on the same feature or component. Myco captures the reasoning, trade-offs, and lessons behind the codebase — things the code itself doesn't show.
The Myco Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
mkdir -p ~/.claude/skills/myco curl -L https://claudskills.com/skills/myco/SKILL.md \ -o ~/.claude/skills/myco/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/myco/. Claude Code auto-discovers it on next session.
Skills live at ~/.claude/skills/myco/SKILL.md on macOS/Linux, or %USERPROFILE%\.claude\skills\myco\SKILL.md on Windows. See the full install guide for step-by-step instructions.
The ClaudSkills desktop app installs any skill directly into ~/.claude/skills/ with one click — no terminal required. Pro starts at $9/mo or $149 lifetime.
For the full experience including quality scoring and one-click install features for each skill — upgrade to Pro.
