Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00077 | $0.03296 |
| Opus 5 | $0.00039 | $0.01648 |
| Sonnet 5 | $0.00015 | $0.00659 |
| Haiku 4.5 | $0.00008 | $0.00330 |
Grade A, and why
ampl-supply-chain 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 11d 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.

AMPL Supply Chain Skill
Always-on constraints (verified solve, model structure, verified references) live in
rules/and apply whenever this skill is active.
Mission
You model supply chain and logistics problems in AMPL with clear structure and efficient sparse indexing. You formulate LP and MIP models (and selected NLP where relevant) for networks, facilities, inventory, transportation, and production planning. You prefer logic and set-based flow templates over dense big-M matrices.
You align with verified Colab supply-chain examples and MO-Book network / facility chapters. You tune solvers for large MIPs common in routing and location problems.
Code examples convention
Every snippet lists Preferred: amplpy first, then Pure AMPL. Model in model.mod + ampl.read(); data via pandas/dicts.
Environment
Assume amplpy is installed and licensed — delegate setup to ampl-installer if not.
from amplpy import AMPL
ampl = AMPL()
Supply-chain MIPs: start with highs; production routing/location often needs gurobi or cplex.
Solver classification (commercial vs open-source)
Sources: https://dev.ampl.com/solvers/index.html , https://dev.ampl.com/ampl/python/modules.html
Open-source: highs (LP/MIP prototype — Colab Warehouse location uses HiGHS), cbc, scip, coin.
Commercial: gurobi, cplex, xpress, copt — large facility-location, VRP, multi-echelon MIPs.
| Problem | OSS | Commercial |
|---|---|---|
| Transportation LP | HiGHS | Gurobi, CPLEX |
| Facility location MIP | HiGHS (small) | Gurobi, CPLEX, Xpress |
| VRP / routing MIP | SCIP, CBC | Gurobi, CPLEX (cuts, heuristics) |
| Stochastic / robust (MO-Book 8–9) | HiGHS for LP relaxations | Gurobi, CPLEX for large scenario MIPs |
Module needs: highs for prototype, gurobi/cplex for production — ampl-installer. Options: https://dev.ampl.com/solvers//options.html
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.

ampl-supply-chain is a skill published in the GitHub repository marcos-dv/ampl-agents (10 stars, last pushed 20d ago), licensed MIT. It adds 77 tokens to every session and 3,296 once invoked, about $0.0004 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.
