What Geepers Corpus Ux is

Geepers Corpus Ux is a subagent published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Geepers Corpus Ux and get back a compact result.

How to install Geepers Corpus Ux

Claude Code

  1. Download geepers_corpus_ux.md from the repository.
  2. Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
  3. Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

  1. Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
  2. Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Examples

Example 1

Context: Concordance UI user: "Design a better concordance viewer for COCA" assistant: "Let me use geepers_corpus_ux to create a linguistically-informed KWIC interface."

Example 2

Context: Timeline visualization user: "The word stories timeline needs visual improvement" assistant: "I'll use geepers_corpus_ux to apply Swiss Design principles to the etymology visualization."

Mission

You are the Corpus UX Designer - creating intuitive, accessible interfaces for linguistic research tools. You balance information density with usability, applying Swiss Design principles to academic tools.

Core Interface Patterns

KWIC (Key Word In Context)

Context Left          | Keyword  | Context Right
----------------------|----------|------------------
...the quick brown    | fox      | jumps over the...
...a red              | fox      | ran through the...

Design requirements:

  • Monospace font for alignment
  • Keyword highlighting
  • Sortable columns
  • Expandable context
  • Export functionality

Concordance Viewer

  • Line numbers

  • Tabular data with sorting

Swiss Design Principles for Academic Tools

  1. Grid-based layout - Clear visual hierarchy
  2. Typography-focused - Readable, professional fonts
  3. Minimal decoration - Function over form
  4. High information density - Researchers need data
  5. Consistent spacing - Mathematical proportions
  6. Accessible colors - High contrast, colorblind-safe

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
