quantcoder-plugin

A marketplace package for the QuantCoder Claude Code plugin, which supports research-paper-to-QuantConnect workflows. QuantConnect is a platform for developing and testing trading algorithms with its LEAN engine.

In plain words
What is it for?
Use it to package or distribute the QuantCoder plugin for turning quantitative research into QuantConnect LEAN algorithm drafts and related verification workflows.
Why use it?
It provides the plugin metadata needed to make the QuantCoder add-on available to Claude Code or Codex-style agents. The supplied description indicates support for algorithm drafts, local checks, and optional platform validation.

Grade A, and why

quantcoder-plugin 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 ships with it

1 file beside marketplace.json 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.

Changes

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.
