A lifecycle hook that runs a Python script after the conversation context has been compressed. Its configuration gives the script a short time limit and adds a small amount of context.

Use it to trigger post-compression session handling through native_lifecycle.py. The available configuration runs the PostCompact action with a five-second timeout.

It restores route or status information after context compression, when earlier conversation details may no longer be directly visible. The excerpt does not specify what the script changes.

Security

Grade A, and why

PostCompact 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 commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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.
