patterns

A skill for browsing recurring analytical patterns saved from earlier analyses.

In plain words
What is it for?
Use it to list patterns, search them by keyword, or inspect patterns for the active dataset or all datasets.
Why use it?
It helps compare a current finding with behaviors that have appeared repeatedly in the available data.

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

patterns 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 3d 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.

Skill: Patterns

Purpose

Browse and search recurring patterns discovered across analyses. Patterns are auto-extracted after each analysis archive and represent behaviors that appear consistently in the data.

When to Use

  • User says /patterns or "what patterns have we seen?"
  • During analysis, to check if a finding matches a known pattern
  • At session start, to remind the user of established behaviors

Invocation

/patterns — list patterns for the active dataset /patterns --global — list patterns across all datasets /patterns search={term} — search patterns by keyword /patterns {id} — show full details for a specific pattern

Instructions

Step 0: Determine Active Dataset

Before loading patterns, identify the active dataset:

  1. Read .knowledge/active.yaml to get the active dataset name
  2. If the file doesn't exist or is empty, default to checking all datasets
  3. Use this dataset name when filtering patterns and referencing dataset-specific files

This ensures you're searching patterns for the correct dataset and providing accurate context.

Step 1: Load Patterns

  1. Check if .knowledge/analyses/_patterns.yaml exists:
    • If it doesn't exist: "No patterns recorded yet. The pattern system initializes after your first analysis is archived."
    • If it exists but is empty: "No patterns recorded yet. Complete 2-3 analyses and recurring patterns will emerge."
  2. If --global flag: also check and read .knowledge/global/cross_dataset_observations.yaml (same existence checks apply).
  3. Load pattern data from existing files.

Step 2: Execute Command

List patterns (/patterns):

  • Filter to active dataset (unless --global)
  • Sort by occurrences descending (most established first)
  • Display as a table: type, description, occurrences, confidence, last seen
  • Show total count

Show specific (/patterns {id}):

  • Display: description, type, all evidence (with analysis IDs), dimensions, metrics, suggested investigation
  • Offer: "Want to investigate this pattern further?"

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.

patterns is a skill published in the GitHub repository ai-analyst-lab/ai-analyst-plugin (32 stars, last pushed 7d ago), licensed MIT. It adds 81 tokens to every session and 1,015 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
