# AgentEligibilityPolicy
## `autogen.AgentEligibilityPolicy`
Bases: `Protocol`
Protocol for runtime eligibility filters in GroupChat speaker selection.
Implement this protocol to remove agents from the candidate set before the speaker selection method (auto/manual/random/round_robin) runs.
Example - always allow all agents (no-op, equivalent to no policy)::
```python
class AllowAll:
def is_eligible(self, agent: Agent, ctx: SelectionContext) -> bool:
return True
```
Example - exclude a specific agent by name::
```python
class ExcludeAgent:
def __init__(self, name: str) -> None:
self.name = name
def is_eligible(self, agent: Agent, ctx: SelectionContext) -> bool:
return agent.name != self.name
```
Multiple policies can be registered on a GroupChat; all must return True for an agent to be considered eligible (AND semantics).
Note
`isinstance(obj, AgentEligibilityPolicy)` only checks that `is_eligible` exists as an attribute -- it does **not** verify the method signature. A class with the wrong arity will fail at call time, not at registration.
### `is_eligible`
```python
is_eligible(agent, ctx)
```
Return True if agent should be included in the candidate set.
