cognitive-variability

Guide conversations through dynamic shifts between zoom levels (scale) and connecting/exploring (intent) to unlock creative breakthroughs and prevent rigid thinking. Use when the user is stuck or needs to develop an idea or when there is a sense of too much repetition or dispersion. Takes the user through several stages of thinking — from idea genesis, to development, to questioning, to disruptive thinking. Identifies structural gaps between idea clusters as spaces for innovation. Tracks temporal dwelling patterns and manages cognitive energy expended. Uses playfulness for difficult transitions from chaos to clarity. Maximum creative potential lives in gaps and dissipative states. Apply for complex analysis, brainstorming, being stuck, breakthroughs, decision paralysis, group facilitation, breaking repetitive patterns, or when grammatical patterns reveal cognitive issues.

What does this agent-skills.md site do?

Agent Skills is a curated directory that indexes skill repositories and lets you browse, preview, and download skills in a consistent format.

03

Where are skills stored in a repo?

By default, the site scans the skills/ folder. You can also submit a URL that points directly to a specific skills folder.

04

What is required inside SKILL.md?

SKILL.md must include YAML frontmatter with at least name and description. The body contains the actual guidance and steps for the agent.
