Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00081 | $0.01015 |
| Opus 5 | $0.00041 | $0.00508 |
| Sonnet 5 | $0.00016 | $0.00203 |
| Haiku 4.5 | $0.00008 | $0.00102 |
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.

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
/patternsor "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:
- Read
.knowledge/active.yamlto get the active dataset name - If the file doesn't exist or is empty, default to checking all datasets
- 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
- Check if
.knowledge/analyses/_patterns.yamlexists:- 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."
- If
--globalflag: also check and read.knowledge/global/cross_dataset_observations.yaml(same existence checks apply). - 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.
