sequant

A marketplace plugin that coordinates coding-agent work from GitHub Issues through separate planning, implementation, and quality-check stages.

In plain words
What is it for?
Use it to take GitHub issues through specification, execution, testing, and review workflows, with support for isolated Git worktrees, separate working directories tied to Git branches, and an MCP server.
Why use it?
It organizes issue resolution into isolated stages and uses separate workspaces and checks to prepare reviewed pull requests, proposed code changes for merging.

Grade A, and why

sequant 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.

Files

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.
