# cao_bibliotheque_familles

WHEN a parametric family (custom shelf, window, bench…) must be reused across projects or shared: the account's family library, like Revit's family library. action=lister: your families then the public ones of others (anonymous author code); action=lire: one family, ready to copy into scene.familles (with its origin); action=enregistrer: save a new version of famille under nom (unchanged definition: no new version), publique to share it. Build and test the family first with cao_famille_essayer.

## Why cao_bibliotheque_familles is rated High

cao_bibliotheque_familles triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

## Use case

AI agents invoke cao_bibliotheque_familles to trigger actions in Immobilier. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Immobilier:
