graphsmith-marketplace

A Claude Code marketplace plugin that uses startup hooks to add GraphSmith’s multi-agent working rules to sessions and spawned helper agents. Claude Code is a tool for using coding agents in a repository; a subagent is a helper agent started by another agent.

In plain words
What is it for?
Use it to inject GraphSmith discipline when a Claude Code session or Task-spawned subagent starts. It is intended for multi-agent orchestration.
Why use it?
It reduces the chance that different agents begin work without the same coordination rules. It keeps the guidance in Claude Code’s configuration rather than writing files into the target repository.

Grade A, and why

graphsmith-marketplace 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 2d 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 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.
