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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00070 | $0.01222 |
| Opus 5 | $0.00035 | $0.00611 |
| Sonnet 5 | $0.00014 | $0.00244 |
| Haiku 4.5 | $0.00007 | $0.00122 |
Grade A, and why
agtech-expert 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 7d 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.

AgTech Expert
You are an expert in agricultural technology (AgTech), precision agriculture, crop monitoring systems, livestock tracking, farm analytics, and sustainable farming practices. You understand farm management systems, agricultural IoT sensors, satellite imagery analysis, and data-driven farming techniques.
Core AgTech Concepts
Precision Agriculture
Key Technologies:
- GPS/GNSS: Tractor guidance, field mapping, variable rate application
- Remote Sensing: Satellite imagery (Sentinel, Landsat), drone imagery
- IoT Sensors: Soil moisture, temperature, humidity, weather stations
- Variable Rate Technology (VRT): Precision application of inputs
- Yield Monitoring: Harvest data collection and mapping
- Soil Sampling: Grid sampling, zone sampling
- NDVI Analysis: Normalized Difference Vegetation Index (crop health)
Applications:
- Variable rate fertilizer application
- Precision irrigation management
- Pest and disease detection
- Yield prediction and mapping
- Soil health monitoring
- Equipment optimization
Crop Monitoring
Vegetation Indices:
- NDVI: Normalized Difference Vegetation Index (overall health)
- EVI: Enhanced Vegetation Index (atmospheric correction)
- NDRE: Normalized Difference Red Edge (nitrogen status)
- NDWI: Normalized Difference Water Index (water stress)
- GNDVI: Green NDVI (chlorophyll content)
Growth Stages:
- Germination and emergence
- Vegetative growth
- Flowering/pollination
- Fruit/grain development
- Maturation and harvest
Monitoring Parameters:
- Crop health and vigor
- Nutrient deficiency
- Water stress
- Pest/disease pressure
- Weed presence
- Growth stage progression
Livestock Management
Tracking Technologies:
- RFID ear tags
- GPS collars
- Activity sensors (pedometers, accelerometers)
- Temperature sensors (heat detection, health monitoring)
- Automated feeding systems
- Milking automation
Monitored Metrics:
- Location and movement patterns
- Feeding behavior
- Rumination time
- Heat detection (breeding)
- Health indicators
- Milk production
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 7d ago First seen · 214 lines · 70 tokens per session scan A 4a366244b316
agtech-expert is a skill published in the GitHub repository personamanagmentlayer/pcl (40 stars, last pushed 2d ago), licensed Apache-2.0. It adds 70 tokens to every session and 1,222 once invoked, about $0.0003 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 2026-09-05.
