3. If you need an implementation template, sample/ and if you need execution commands, script/ refer to
4. Follow links if there are related topics

Guide to sample/ and script/

• sample/ ── Working examples (minimal working samples for each feature)
• script/ ── Collection of executable commands (hook scripts, config generation utilities, etc.)

How to update

If the official documentation URLs change or you need to reflect specification updates, update-reference Re-fetch and update each reference/*.md with the skill. At the beginning of each file, <!-- source: <URL> --> と <!-- 最終確認日: YYYY-MM-DD --> update.

Verification

After adding or updating reference/*.md, verify consistency with the following.

# 索引に記載されたファイルが実在するか確認
ls skills/claude-code-reference/reference/

• For each row in the SKILL.md index table, the corresponding reference/<topic>.md must exist
• At the top of each file, <!-- source: ... --> と <!-- 最終確認日: ... --> that there is
• If there are files not listed in the index, add them to the index table in SKILL.md
