What is combinatorial-optimization?

A collection of guides for solving decision and planning problems with mathematical optimization and search methods. It includes models, decomposition techniques, and algorithms for problems such as routing, scheduling, packing, and facility placement.

Use it to model or solve combinatorial problems with mixed-integer programming, decomposition, or metaheuristics, and to benchmark optimization methods.

It gives developers a starting point for choosing a suitable way to represent and solve a difficult optimization problem. It also covers cases where an exact answer may be impractical and a heuristic is needed.

Security

Grade A, and why

combinatorial-optimization 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 yesterday.

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 installs

The manifest is a name and a version. 76 skills travel with it, and installing the plugin installs all of them — 9,357 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#combinatorial-optimization 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.

combinatorial-optimization is a plugin published in the GitHub repository hajibabaie/combinatorial-optimization-skills (7 stars, last pushed 2mo ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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.
