Install
Skills CLI
npx skills add shinpr/rashomon
Asks which skills and agents to install. Just one: npx skills add shinpr/rashomon --skill knowledge-base — add -g for every project.
Claude Code
git clone https://github.com/shinpr/rashomoncp -r "rashomon/skills/knowledge-base" ~/.claude/skills/
Copies the knowledge-base skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add shinpr/rashomon
Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.
Skills can run code on your machine — read the SKILL.md first.
What it does
In the author's own words, from each skill's SKILL.md.
-
knowledge-base
Retrieves and updates project-specific prompt knowledge from comparison evidence and user feedback. Use only for prompt analysis or post-comparison learning within a Rashomon evaluation.
skills/knowledge-base/SKILL.md on GitHub (opens in a new tab) -
prompt-optimization
Improves LLM-facing context while preserving intent, execution boundaries, and proportional work. Use when creating or reviewing prompts, agent definitions, skill definitions, or other instructions for an LLM.
skills/prompt-optimization/SKILL.md on GitHub (opens in a new tab) -
recipe-eval-prompt
Compares original and optimized prompts through repeated blind paired execution in git worktrees. Use when evaluating prompt improvement effects or learning prompt engineering through concrete examples.
skills/recipe-eval-prompt/SKILL.md on GitHub (opens in a new tab) -
recipe-eval-skill
Creates or updates Claude Code skills through interactive dialog, then evaluates effectiveness with sequential paired comparisons. Use when creating new skills, updating existing skills, or evaluating skill quality.
skills/recipe-eval-skill/SKILL.md on GitHub (opens in a new tab) -
worktree-execution
Creates, pins, and cleans isolated Git worktree pairs for comparison trials. Use only when a Rashomon prompt or skill evaluation needs paired execution environments or orphan recovery.
skills/worktree-execution/SKILL.md on GitHub (opens in a new tab)
No skill matches that filter.
Review before you install
A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
