skills-store: Skill for Claude Code

.claude/skills/irasutoya-search/SKILL.md

irasutoya-search is a skill for Claude Code from Mineru98/skills-store. It costs 200 tokens per session (1,978 once invoked), scanned A, original, MIT.

A command-line search tool for Irasutoya, a Japanese illustration library. It finds and previews up to three matching illustrations and provides their page and image URLs.

In plain words
What is it for?
Use it to search by topic, phrase, scene, object, action, or emotion, or to get a random illustration or command help.
Why use it?
It saves time when you need a specific Irasutoya illustration but do not know the Japanese search terms or how to use the command.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

irasutoya-search scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Overview

Use the installed irasutoya command-line tool to find Irasutoya illustrations. The skill drives the CLI that is already installed on the system — it does not run, build, or modify any Ruby source. Optimize vague or natural-language requests into short Japanese search candidates before reporting results.

Command Choice

  • Use irasutoya random when the user wants an arbitrary Irasutoya image.
  • Use irasutoya search "query" when the user gives a topic, keyword, or phrase.
  • Use irasutoya help or irasutoya help COMMAND when the user asks what is available.

Expected commands:

irasutoya random
irasutoya search "cat"
irasutoya help search

The search command returns up to 3 matching images. Each result prints:

  • Page URL
  • Title
  • Description
  • one or more Image URL lines
  • an inline image preview when the terminal supports it

Fast Search Workflow

  1. Parse the request into visual facets:
    • subject: person, animal, object, role, age, gender
    • action/pose: observing, wondering, eating, running, pointing
    • emotion/expression: curious, doubtful, happy, surprised, worried
    • props/context: magnifying glass, question mark, school, office
  2. Generate 2-4 concise query candidates. Prefer Japanese nouns and short noun phrases because Irasutoya titles/descriptions are Japanese.
  3. Search candidates in parallel when possible. Avoid launching many broad searches; stop once a strong match appears.
  4. Score results before reporting. Prefer results whose title or description matches at least two facets.
  5. Return the best result first, with any close alternative only if it captures a different interpretation.

Pass condition: the first search batch should produce a 4-5 point result in the top two results for at least one candidate query. If it does not, run one refinement batch using the failure rules below.

Query Rubric

Score each candidate result from 0-5:

  • +2 subject match: correct character/object type, such as 男の子.
  • +1 action/pose match: the visible activity matches, such as 観察.
  • +1 emotion/expression match: the description/title implies the requested feeling, such as 不思議そう, 疑問, or はてな.
  • +1 prop/context match: important visual prop or setting appears, such as 虫眼鏡.
  • +1 single-scene match: one concrete illustration, not a sheet of variations, when the user asked for one image.
  • -1 if the result is too generic, multi-image, or only one small sub-image matches.
  • -1 if the title includes いろいろな, 表情, or パーツ別 and the user asked for one concrete scene.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
