cluster-documents

cluster-documents is a skill for Claude Code, Codex from dandye/ai-runbooks. It costs 24 tokens per session (452 once invoked), scanned A, original, Apache-2.0.

A tool that groups documents by similar topics, purpose, or wording. It can also identify documents that do not fit a group and label each group.

In plain words
What is it for?
Use it to organize a repository of documents and optionally produce data for a chart showing the groups.
Why use it?
It helps make sense of large document collections and reveals duplicates, related material, and isolated files.

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.

Security

Grade A, and why

cluster-documents 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 10d ago.

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

Document Clustering Skill

Analyze a repository of documents to group them based on content similarity, topic, or purpose. This skill helps organize large collections, identify redundancies, and discover relationships.

Inputs

  • PATH - The repository to analyze (e.g., "/repository")
  • SIMILARITY_THRESHOLD - (Optional) Float (0.0-1.0), threshold for grouping (default: 0.8)
  • VISUALIZATION - (Optional) Boolean, whether to generate a visual representation (default: false)

Workflow

Step 1: Text Processing

Ingest documents from PATH.

  • Normalize text (remove stop words, stemming/lemmatization).
  • Generate embeddings or TF-IDF vectors for each document.

Step 2: Clustering Analysis

Apply clustering algorithms (e.g., K-Means, DBSCAN) to the document vectors.

  • Group documents that meet the SIMILARITY_THRESHOLD.
  • Identify outliers or unique documents.

Step 3: Cluster Labeling

Analyze the centroid or representative terms of each cluster to assign a meaningful label (Topic).

Step 4: Output Generation

Generate the clustering report.

  • If VISUALIZATION is true, create a scatter plot or dendrogram data.

Required Outputs

A CLUSTERING_REPORT object containing:

  • Cluster List: ID, Label, and List of Documents in each cluster.
  • Redundancy Report: Sets of highly similar documents (potential duplicates).
  • Visualization Data: (If requested) Coordinates for plotting.

Quick Reference

  • Purpose: Organize unstructured content and find duplicates.
  • Techniques: Text Mining, NLP, Vector Space Models.

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.
