name: demo-hello description: Demo skill that shows a realistic Clawdbot/Codex skill bundle layout (SKILL.md + scripts) and provides a useful, deterministic utility (summarize a text/log file into markdown stats). Use when you want a copyable template skill, a sanity-check that script execution works, or a quick way to summarize logs/notes.

Demo Hello

What this skill contains

• SKILL.md: this file (metadata + instructions)
• scripts/hello.js: minimal “hello world” script
• scripts/summarize-text.js: reads a file or stdin and outputs a markdown summary (stats + top frequent words)

Use

Quick demo (hello)

Run the bundled script to show deterministic output:

node scripts/hello.js --name "Taotao"

Real-ish demo (summarize a log/text file)

Summarize a file:

node scripts/summarize-text.js --file ./some.log --top 12

Or pipe stdin:

cat ./some.log | node scripts/summarize-text.js --top 12

How to use this skill as a template

• Copy skills/demo-hello/ and rename the folder.
• Update the YAML frontmatter name + description.
• Add one deterministic script in scripts/ that:
  • accepts CLI args
  • produces stable output
  • can be run by the agent to avoid “LLM guessing”
• Keep SKILL.md short; put longer docs into references/ if needed.
