  Network · Resolve the product

• Reads the store pickup stock for the product (getStorePickupStock)

  Needs a login-free token from Daiso Mall, encrypted with a key the instructions say is hard-coded in Daiso JavaScript and may change. A stock of 0 or empty means none.

• Reports store, product and stock, and says plainly when no shelf location is shown

Watch out for

• Claude runs whatever the k-skill npm package prints

  SKILL.md says to run npx -y @nomadamas/k-skill@0 instruct daiso-product-search and follow its output as the primary instructions. Claude therefore acts on text that comes from an npm package at run time, and the @0 tag floats across 0.x releases, so the instructions can change without any change to SKILL.md. SKILL.md also lists an update command. The same text is in the repo as daiso-product-search/instruction.md. Read the output before Claude acts on it. github.com

• It installs an npm package

  The instructions ask for `npm install daiso-product-search` and say not to call Daiso Mall directly if the install is blocked.

• It uses a login-free Daiso token for stock

  Stock lookups need a token from Daiso Mall that the skill encrypts with a key the instructions say is hard-coded in Daiso JavaScript. The legal notice limits use to personal lookups, not bulk crawling.

• The k-skill CLI can send usage statistics

  The docs say it sends a random local ID, the command and skill name, CLI version, runtime mode and success flag, but not arguments, input, file contents or credentials. Set KSKILL_ANALYTICS_DISABLED=1 to opt out.

• Hard rules in SKILL.md

  SKILL.md says never to run payment, message delivery, final submission, cancellation or public posting without explicit approval immediately beforehand, and never to ask for, print or store plaintext credentials in chat, files or shell arguments.
