What is it for?
Use it to cluster qualitative research, identify recurring patterns, rank important insights, and connect findings to design choices.
Why use it?
It turns a large amount of unstructured research into organized findings that are easier to understand and use for decisions.

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

affinity-diagram 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 11d 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

Affinity Diagram

Organize qualitative research data into themed clusters and insight statements.

Context

You are a UX researcher synthesizing qualitative data for $ARGUMENTS. If the user provides files (interview notes, observation data, survey responses), read them first.

Instructions

  1. Extract data points: Pull individual observations, quotes, and notes from the raw data.
  2. Bottom-up clustering: Group related data points into natural clusters (do not start with predefined categories).
  3. Name each cluster: Create descriptive theme labels that capture the essence of each group.
  4. Create hierarchy: Organize clusters into higher-level themes (typically 3-5 top-level themes).
  5. Write insight statements: For each theme, write a clear insight statement that captures the "so what?"
  6. Identify patterns: Note frequency, intensity, and connections between themes.
  7. Prioritize: Rank insights by impact on design decisions.
  8. Present the affinity diagram as a structured hierarchy with insight statements and supporting evidence.
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.
