Skill Extractor

Captures reusable knowledge from the current session and persists it to the liuyinglao/my-claude-skills repo so it's available on all devices.

What to Extract

1. curl / HTTP fetches

When curl or any HTTP fetch was used to retrieve an external resource:

• Record the URL, purpose, and any flags/headers used
• Save as a reference entry under references/ in the relevant skill folder

2. Local commands

When a shell command was run to complete a task:

• Document the command pattern, flags, and what it does
• Note any gotchas or preconditions (e.g. required tools, working directory)
• Save as a reusable recipe in the relevant skill

3. URLs and documents provided by the user

When the user provides a URL or attaches a document:

• Fetch and summarize the content if it contains reusable knowledge
• Copy the key content or a structured summary as a reference file

Extraction Process

Step 1 — Identify extractable patterns

Review the conversation for:

• Commands run with Bash
• URLs fetched or provided
• Techniques, workflows, or configurations that solved a problem
• Any knowledge the user explicitly shared

Step 2 — Match against existing skills

Read the repo at /Users/yinglaoliu/Downloads/liuyinglao/my-claude-skills/plugins/my-skills/skills/ and check each existing skill's SKILL.md.

• If a match exists: extend the existing SKILL.md with the new knowledge. Add reference files to that skill's folder if needed.
• If no match: create a new skill folder with a SKILL.md following the format below.

Step 3 — Write the skill content

New skill format:

---
name: skill-name
description: When to use this skill — include trigger phrases and keywords
version: 1.0.0
---

# Skill Name

## What This Skill Does
[One paragraph summary]

## Techniques / Commands
[Document commands, patterns, recipes]

## References
[Links or summaries of external resources]

Reference file format (for URLs/docs, save as references/<topic>.md):

# <Topic>

Source: <URL or "user-provided">
Retrieved: <date>

## Summary
[Key information extracted]

## Raw / Key Excerpts
[Relevant content]

Step 4 — Commit and push

After writing all files:

cd /Users/yinglaoliu/Downloads/liuyinglao/my-claude-skills
git add .
git commit -m "skill: <summary of what was extracted>"
git push

Confirm to the user which skills were updated or created, and the commit URL.

Guidelines

• Keep skills focused — one domain per skill folder
• Prefer extending existing skills over creating new ones
• Reference files live inside the skill folder they support
• Never commit secrets, tokens, or personal data
• The description field is critical — write it so Claude knows exactly when to activate the skill
