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 5.1 | $0.00029 | $0.00244 |
| Opus 5 | $0.00015 | $0.00122 |
| Sonnet 5 | $0.00006 | $0.00049 |
| Haiku 4.5 | $0.00003 | $0.00024 |
Grade A, and why
data-processing 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.
What it actually says
Data Processing
Use Pandas to filter travel datasets efficiently.
Example Usage
import pandas as pd
def filter_restaurants(df, city, cuisines):
# Filter by city
city_df = df[df['City'].str.lower() == city.lower()]
# Filter by cuisines (assuming Cuisines is a string like "American, Italian")
pattern = '|'.join(cuisines)
return city_df[city_df['Cuisines'].str.contains(pattern, case=False, na=False)]
def filter_accommodations(df, city, budget_per_night, pet_friendly=True):
city_df = df[df['city'].str.lower() == city.lower()]
if pet_friendly:
# Assuming pet-friendly means 'No pets' is NOT in house_rules
city_df = city_df[~city_df['house_rules'].str.contains('No pets', case=False, na=False)]
return city_df[city_df['price'] <= budget_per_night]
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.

data-processing is a skill published in the GitHub repository cxcscmu/SkillLearnBench (83 stars, last pushed 1mo ago), licensed MIT. It adds 29 tokens to every session and 244 once invoked, about $0.0001 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 2026-09-03.
