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 | $0.00060 | $0.00389 |
| Opus 5 | $0.00030 | $0.00195 |
| Sonnet 5 | $0.00012 | $0.00078 |
| Haiku 4.5 | $0.00006 | $0.00039 |
Grade A, and why
evo-supply-shock 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 9d 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
Supply-Side Shock Analysis Skill
Overview
This skill implements a complete workflow for estimating the impact of an investment spending shock on a small open economy using:
- Data collection from PWT (capital stock), IMF WEO (GDP), and ECB (CFC)
- HP filter for trend extraction in Excel
- Cobb-Douglas production function for potential GDP estimation
- Investment shock modeling
Usage
import sys
sys.path.insert(0, '/app/environment/skills/evo-supply-shock/scripts')
from data_collection import collect_pwt_data, collect_weo_data, collect_ecb_cfc_data
from excel_builder import build_supply_model
from validator import validate_workbook
# End-to-end entry point
build_supply_model(
template_path='/root/test-supply.xlsx',
output_path='/root/test-supply.xlsx'
)
# Validate
validate_workbook('/root/test-supply.xlsx')
Workflow Steps
- Data Collection: Download PWT, WEO, ECB data programmatically
- Populate PWT Sheet: Fill rnna and rgdpna columns
- Populate WEO Sheet: Fill real GDP level and growth rate, extend to 2043
- Populate CFC Sheet: Fill CFC data, link capital stock, calculate depreciation
- Production Sheet: Set up HP filter formulas, production function
- Run LibreOffice Solver: Optimize HP filter via macro
- Validate: Check formulas and results
What ships with it
3 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.

evo-supply-shock is a skill published in the GitHub repository Zhang-Henry/CoEvoSkills (66 stars, last pushed 22d ago), licensed Apache-2.0. It adds 60 tokens to every session and 389 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 2026-09-03.
