What is claude-session-driver marketplace?

About the project

obra/claude-session-driver is a command-line tool that lets one coding-agent session launch, control, observe, and collect results from other agent sessions running as workers. It is for delegating tasks across Claude Code, Codex, or Pi workers in parallel through tmux, with lifecycle events recorded for monitoring. The catalogue entries provide its hooks, plugins, and skill.

Getting it into your agent

Security

Grade A, and why

claude-session-driver 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 28d 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.

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.
