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 | $0.00097 | $0.02242 |
| Opus 5 | $0.00048 | $0.01121 |
| Sonnet 5 | $0.00019 | $0.00448 |
| Haiku 4.5 | $0.00010 | $0.00224 |
Grade A, and why
gridstatus-api scanned grade A with 1 finding 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
**IMPORTANT: Always use the Python SDK.** The direct curl API has issues with date filtering on the free tier and returns stale sample data. The Python SDK correctly handles all parameters. How it starts

GridStatus API Skill
Query electricity grid data from US Independent System Operators (ISOs) using the GridStatus.io API. Access real-time and historical data for load, pricing (LMP), generation, fuel mix, and more.
Quick Start
IMPORTANT: Always use the Python SDK. The direct curl API has issues with date filtering on the free tier and returns stale sample data. The Python SDK correctly handles all parameters.
Setup
- Install SDK (use uv for isolation):
cd /tmp && uv venv -q && source .venv/bin/activate && uv pip install gridstatusio pandas -q
-
API Key: Check for
GRIDSTATUS_API_KEYin the user's.envfile. If not present, instruct the user to:- Create account at https://www.gridstatus.io
- Get API key from Settings page
- Add to
.env:GRIDSTATUS_API_KEY=your_key_here
-
Query data:
import os
os.environ['GRIDSTATUS_API_KEY'] = 'key_from_dotenv'
from gridstatusio import GridStatusClient
client = GridStatusClient()
df = client.get_dataset(
dataset="isone_fuel_mix",
start="2026-01-25",
end="2026-01-26",
limit=100
)
print(df.tail())
Free tier limit: 500,000 rows per month. Always use limit parameter.
Supported ISOs
| ISO | Region | Key Datasets |
|---|---|---|
| ERCOT | Texas | ercot_load, ercot_spp_*, ercot_fuel_mix |
| CAISO | California | caiso_load, caiso_lmp_*, caiso_fuel_mix |
| PJM | Mid-Atlantic/Midwest | pjm_load, pjm_lmp_*, pjm_standardized_* |
| MISO | Midwest | miso_load, miso_lmp_* |
| NYISO | New York | nyiso_load, nyiso_lmp_* |
| ISO-NE | New England | isone_load, isone_lmp_*, isone_fuel_mix |
| SPP | Southwest/Central | spp_load, spp_lmp_* |
See references/datasets-by-iso.md for complete dataset catalog.
Standard Query Template
Use this template for all queries. Run in a Python heredoc:
cd /tmp && source .venv/bin/activate && python3 << 'EOF'
import os
os.environ['GRIDSTATUS_API_KEY'] = 'YOUR_KEY_HERE'
from gridstatusio import GridStatusClient
client = GridStatusClient()
df = client.get_dataset(
dataset="DATASET_NAME",
start="YYYY-MM-DD",
end="YYYY-MM-DD",
limit=100
)
print(df.to_string())
EOF
What ships with it
7 files 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.

gridstatus-api is a skill published in the GitHub repository MisterClean/claude-plugins (3 stars, last pushed 7mo ago), licensed MIT. It adds 97 tokens to every session and 2,242 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
