* Support shell command execution for API key resolution in models.json
Add ! prefix support to apiKey field in models.json to execute shell commands
and use stdout as the API key. This allows users to store API keys in secure
credential managers like macOS Keychain, 1Password, Bitwarden, or HashiCorp Vault.
Example: "apiKey": "!security find-generic-password -ws 'anthropic'"
The apiKey field now supports three formats:
- !command - executes shell command, uses trimmed stdout
- ENV_VAR_NAME - uses environment variable value
- literal - uses value directly
fixes#697
* feat(coding-agent): cache API key command results for process lifetime
Shell commands (! prefix) are now executed once and cached. Environment
variables and literal values are not cached, so changes are picked up.
Addresses review feedback on #762.

Builds on #406 to support simpler proxy use case:
- Override just baseUrl to route built-in provider through proxy
- All built-in models preserved, no need to redefine them
- Full replacement still works when models array is provided
* Allow models.json to override built-in providers
When a provider is defined in models.json with the same name as a
built-in provider (e.g., 'anthropic', 'google'), the built-in models
for that provider are completely replaced by the custom definition.
This enables users to:
- Use custom base URLs (proxies, self-hosted endpoints)
- Define a subset of models they want available
- Customize model configurations for built-in providers
Example usage in ~/.pi/agent/models.json:
{
"providers": {
"anthropic": {
"baseUrl": "https://my-proxy.example.com/v1",
"apiKey": "ANTHROPIC_API_KEY",
"api": "anthropic-messages",
"models": [...]
}
}
}
* Refactor model-registry for readability
- Extract CustomModelsResult type and emptyCustomModelsResult helper
- Extract loadBuiltInModels method with clear skip logic
- Simplify loadModels with destructuring and ternary
- Reduce repetition in error handling paths
* Refactor model-registry tests for readability
- Extract providerConfig() helper to hide irrelevant model fields
- Extract writeModelsJson() helper for file writing
- Extract getModelsForProvider() helper for filtering
- Move modelsJsonPath to beforeEach
Reduces test file from 262 to 130 lines while maintaining same coverage.
