A tool for turning long text into a short bullet-point summary, with basic counts such as words, sentences, and average sentence length.

In plain words
What is it for?
Use it to summarize supplied text, limit the number of key points, and produce a Markdown summary file and a JSON statistics file.

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.

Fable 5.1 $0.00014 $0.00404
Opus 5.5 $0.00006 $0.00162

Security

Grade A, and why

text_summarizer 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/main.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Text Summarizer Skill

A more complex example that demonstrates text processing capabilities.

What it does

This skill takes a long piece of text and:

  1. Analyzes the text (word count, sentence count, etc.)
  2. Extracts key points
  3. Creates a bullet-point summary
  4. Generates a statistics report

Usage

Input

{
  "text": "Your long text here...",
  "max_points": 5
}

Output

{
  "summary": "• Point 1\n• Point 2\n• Point 3",
  "stats": {
    "word_count": 150,
    "sentence_count": 8,
    "avg_sentence_length": 18.75
  }
}

Artifacts

  • summary.md: Markdown file with the formatted summary
  • stats.json: JSON file with detailed statistics

Algorithm

This is a simple implementation that:

  1. Splits text into sentences
  2. Scores sentences by length and position
  3. Selects top N sentences as summary points

Note: This is a demonstration. For production use, consider using NLP libraries like spaCy or transformers.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
