Custom Agent agendSpawn hook running for all prompts
Checks
- [x] I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
- [x] I have run
q doctorin the affected terminal session - [x] I have run
q restartand replicated the issue again
Operating system
macOS 15.6.0 (24G84)
Expected behaviour
This is my full custom agent config:
{
"name": "hbt",
"description": "redacted",
"resources": [
"redacted"
],
"tools": [
"*"
],
"allowedTools": [
"fs_read"
],
"toolsSettings": {
"execute_bash": {
"alwaysAllow": [
{
"preset": "readOnly"
}
]
}
},
"hooks": {
"agentSpawn": [
{
"command": "pwd",
"timeout_ms": 5000
},
{
"command": "git status",
"timeout_ms": 5000
}
]
},
"mcpServers": {
}
}
And I expected the git status agentSpawn hook to only run on init.
Actual behaviour
But if I initialise this agent in a non-git folder, it seems the command is being run for every propmt. See below conversation:
