Pull Request: fix(cli): load providers from ProviderRegistry and restore code generators

Branch: fix/cli-init-providers-and-argo-url -> next
Repository: als-apg/osprey
PR Link: https://github.com/als-apg/osprey/pull/new/fix/cli-init-providers-and-argo-url

---

Summary

• Fix osprey interactive init failing at provider and code generator selection steps
• get_provider_metadata() now reads from ProviderRegistry (the actual source of truth) instead of the empty config.providers list
• get_code_generator_metadata() restored with basic and claude_code entries
• Updated Argo provider default_base_url to https://apps.inside.anl.gov/argoapi/v1

Problem

Running osprey (interactive project creation) fails with two errors that block project creation:

! No providers could be loaded from osprey registry

✗ No code generators available
! Osprey could not load any code generators.
Check that osprey is properly installed: uv sync --all-extras

The init wizard aborts at Step 5 (Code Generator), preventing any project from being created.

Root Cause

1. Providers not loading

The next branch moved provider definitions from the registry config to a standalone ProviderRegistry in osprey.models.provider_registry. The CLI function get_provider_metadata() in interactive_menu.py still read from the old location (config.providers), which is now an empty list [].

2. Code generators not loading

The function get_code_generator_metadata() in interactive_menu.py had its implementation replaced with a hardcoded empty dict:

# Code generators were removed from the registry
generators = {}

However, the scaffolding code in scaffolding.py still expects "basic" and "claude_code" as valid generator values.

3. Argo base URL outdated

The Argo provider's default base URL (https://argo-bridge.cels.anl.gov) is no longer the active endpoint.

Changes

src/osprey/cli/interactive_menu.py

get_provider_metadata() (~line 326):

Before:

from osprey.registry.builtins import FrameworkRegistryProvider
framework_registry = FrameworkRegistryProvider()
config = framework_registry.get_registry_config()
for provider_reg in config.providers:  # empty list
    module = importlib.import_module(provider_reg.module_path)
    provider_class = getattr(module, provider_reg.class_name)
    ...

After:

from osprey.models.provider_registry import get_provider_registry
pr = get_provider_registry()
for provider_name in pr.list_providers():
    provider_class = pr.get_provider(provider_name)
    ...

get_code_generator_metadata() (~line 423):

Replaced generators = {} with entries for the two generators the scaffolding code expects:

• basic -- always available (built-in single-pass LLM generator)
• claude_code -- available when claude-agent-sdk is installed (checked via importlib)

src/osprey/models/providers/argo.py

Updated the base URL in two places:

Location	Old	New
Line 73 (fallback in _execute_argo_structured_output())	https://argo-bridge.cels.anl.gov	https://apps.inside.anl.gov/argoapi/v1
Line 145 (default_base_url class attribute)	https://argo-bridge.cels.anl.gov	https://apps.inside.anl.gov/argoapi/v1

Verification

source /home/oxygen/SHANG/next_osprey/.venv/bin/activate
python3 -c "
from osprey.cli.interactive_menu import get_provider_metadata, get_code_generator_metadata

providers = get_provider_metadata()
print(f'Providers loaded: {len(providers)}')
for name in sorted(providers):
    print(f'  {name}')

generators = get_code_generator_metadata()
print(f'Code generators loaded: {len(generators)}')
for name, meta in sorted(generators.items()):
    print(f'  {name}: available={meta[\"available\"]}')
"

Expected output:

Providers loaded: 11
  als-apg
  amsc
  anthropic
  argo
  asksage
  cborg
  google
  ollama
  openai
  stanford
  vllm
Code generators loaded: 2
  basic: available=True
  claude_code: available=True

Test Plan

• Run osprey and verify all 11 providers appear at Step 6 (Provider Selection)
• Verify both code generators (basic, claude_code) appear at Step 5 (Code Generator)
• Complete a full osprey init project creation flow end-to-end
• Verify Argo provider health check uses the new base URL
• Run unit tests: pytest tests/ --ignore=tests/e2e -v

@hshang315 I think this PR should target the next branch, not the main. Main branch is still the old backend.
