A plugin that lets a coding agent send separate tasks to parallel workers in isolated Git workspaces. Git workspaces are separate working copies of the same project, so tasks can be handled without directly sharing files.

Use it to delegate multiple coding tasks that can be worked on independently, with each task assigned to its own isolated Git workspace.

It helps divide independent work and run it at the same time. Isolation reduces the chance that one worker's changes interfere with another worker's task.

Security

Grade A, and why

subtask 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 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.
