80 20 Rule

skill

Author’s activation text, quoted as published

Use this skill whenever the design has many features, controls, or content elements and decisions about which to prioritize matter — feature roadmaps, redesign scoping, IA decisions, dashboard design, settings page audits, marketing content prioritization, or any design with many candidates competing for attention. Trigger when the user asks "what should we focus on?", "should we add another feature?", "what can we cut?", or when reviewing a UI cluttered with rarely-used controls. The 80/20 rule (Pareto principle) is one of the foundational principles in ''Universal Principles of Design'' (Lidwell, Holden, Butler 2003) and one of the most quoted across design, business, and engineering.

Security audit

Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.

Its own instructions

Its SKILL.md says when to use it and covers setup.

Read from the capability’s own SKILL.md. This is not a grade and does not compare to the instruction-depth verdict on an MCP server — a skill has no tools to document, so that rubric does not apply to it.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.

tashan Pro$6/mo

Pro adds the history to tashan doctor, so a run over your own config says which of yours gained an advisory, started running an install script, or lost its last maintainer — and what to move to.
