Summary

CLEVERAGENTS_TESTING_USE_MOCK_AI is a widely-used environment variable (88 references across the codebase) that controls whether the mock AI provider is used in tests. However, it is not declared as a field in Settings — it is read directly via os.environ.get() / os.getenv() in multiple places including plan_service.py, container.py, actor_service.py, and CLI commands. This bypasses the Settings abstraction entirely, making it impossible to configure via pydantic-settings mechanisms (.env files, prefixed env vars, etc.) and leaving it undocumented in the settings schema.

Expected Behavior

CLEVERAGENTS_TESTING_USE_MOCK_AI should be declared as a Settings field (e.g., testing_use_mock_ai: bool) with a validation_alias so it can be:

Discovered via Settings.model_fields
Configured via .env files
Validated and type-coerced by pydantic
Documented alongside other settings

Actual Behavior

# src/cleveragents/application/services/plan_service.py
def _is_testing_mode(self) -> bool:
    return os.environ.get("CLEVERAGENTS_TESTING_USE_MOCK_AI", "").lower() in (
        "true", "1", "yes"
    )

# src/cleveragents/application/container.py
os.environ.get("CLEVERAGENTS_TESTING_USE_MOCK_AI", "").lower()

# src/cleveragents/application/services/actor_service.py
os.environ.get("CLEVERAGENTS_TESTING_USE_MOCK_AI", "")

Meanwhile, Settings has a mock_providers field for a related but different purpose:

# src/cleveragents/config/settings.py
mock_providers: bool = Field(
    default=False,
    validation_alias=AliasChoices("CLEVERAGENTS_MOCK_PROVIDERS"),
    ...
)

The two env vars serve overlapping purposes but are handled inconsistently:

CLEVERAGENTS_MOCK_PROVIDERS → Settings.mock_providers (proper Settings field)
CLEVERAGENTS_TESTING_USE_MOCK_AI → raw os.environ.get() (bypasses Settings)

Impact

CLEVERAGENTS_TESTING_USE_MOCK_AI cannot be set via .env files or pydantic-settings mechanisms
The variable is not validated — typos like CLEVERAGENTS_TESTING_USE_MOCK_AI=True (capital T) are silently ignored in some places but not others (inconsistent parsing)
The variable is not documented in Settings docstrings or the spec's configuration reference
docs/api/providers.md lists CLEVERAGENTS_TESTING_USE_MOCK_AI as a supported env var, but it has no corresponding Settings field
The coexistence of CLEVERAGENTS_MOCK_PROVIDERS and CLEVERAGENTS_TESTING_USE_MOCK_AI creates confusion about which to use

Code Locations

src/cleveragents/application/services/plan_service.py — lines 106, 232
src/cleveragents/application/container.py — line 187
src/cleveragents/application/services/actor_service.py — line 187
src/cleveragents/cli/commands/plan.py — lines 898, 1001
src/cleveragents/config/settings.py — missing field

Fix Direction

Add testing_use_mock_ai as a Settings field and update all call sites:

# src/cleveragents/config/settings.py
testing_use_mock_ai: bool = Field(
    default=False,
    validation_alias=AliasChoices("CLEVERAGENTS_TESTING_USE_MOCK_AI"),
    description=(
        "When True, use mock AI providers instead of real LLM backends. "
        "For testing only. Do not use in production."
    ),
)

Then update all os.environ.get("CLEVERAGENTS_TESTING_USE_MOCK_AI", ...) calls to use settings.testing_use_mock_ai.

Alternatively, consolidate CLEVERAGENTS_TESTING_USE_MOCK_AI and CLEVERAGENTS_MOCK_PROVIDERS into a single mock_providers flag (they serve the same purpose) and add CLEVERAGENTS_TESTING_USE_MOCK_AI as an alias.

## Summary `CLEVERAGENTS_TESTING_USE_MOCK_AI` is a widely-used environment variable (88 references across the codebase) that controls whether the mock AI provider is used in tests. However, it is **not** declared as a field in `Settings` — it is read directly via `os.environ.get()` / `os.getenv()` in multiple places including `plan_service.py`, `container.py`, `actor_service.py`, and CLI commands. This bypasses the `Settings` abstraction entirely, making it impossible to configure via `pydantic-settings` mechanisms (`.env` files, prefixed env vars, etc.) and leaving it undocumented in the settings schema. ## Expected Behavior `CLEVERAGENTS_TESTING_USE_MOCK_AI` should be declared as a `Settings` field (e.g., `testing_use_mock_ai: bool`) with a `validation_alias` so it can be: 1. Discovered via `Settings.model_fields` 2. Configured via `.env` files 3. Validated and type-coerced by pydantic 4. Documented alongside other settings ## Actual Behavior ```python # src/cleveragents/application/services/plan_service.py def _is_testing_mode(self) -> bool: return os.environ.get("CLEVERAGENTS_TESTING_USE_MOCK_AI", "").lower() in ( "true", "1", "yes" ) # src/cleveragents/application/container.py os.environ.get("CLEVERAGENTS_TESTING_USE_MOCK_AI", "").lower() # src/cleveragents/application/services/actor_service.py os.environ.get("CLEVERAGENTS_TESTING_USE_MOCK_AI", "") ``` Meanwhile, `Settings` has a `mock_providers` field for a related but different purpose: ```python # src/cleveragents/config/settings.py mock_providers: bool = Field( default=False, validation_alias=AliasChoices("CLEVERAGENTS_MOCK_PROVIDERS"), ... ) ``` The two env vars serve overlapping purposes but are handled inconsistently: - `CLEVERAGENTS_MOCK_PROVIDERS` → `Settings.mock_providers` (proper Settings field) - `CLEVERAGENTS_TESTING_USE_MOCK_AI` → raw `os.environ.get()` (bypasses Settings) ## Impact - `CLEVERAGENTS_TESTING_USE_MOCK_AI` cannot be set via `.env` files or `pydantic-settings` mechanisms - The variable is not validated — typos like `CLEVERAGENTS_TESTING_USE_MOCK_AI=True` (capital T) are silently ignored in some places but not others (inconsistent parsing) - The variable is not documented in `Settings` docstrings or the spec's configuration reference - `docs/api/providers.md` lists `CLEVERAGENTS_TESTING_USE_MOCK_AI` as a supported env var, but it has no corresponding `Settings` field - The coexistence of `CLEVERAGENTS_MOCK_PROVIDERS` and `CLEVERAGENTS_TESTING_USE_MOCK_AI` creates confusion about which to use ## Code Locations - `src/cleveragents/application/services/plan_service.py` — lines 106, 232 - `src/cleveragents/application/container.py` — line 187 - `src/cleveragents/application/services/actor_service.py` — line 187 - `src/cleveragents/cli/commands/plan.py` — lines 898, 1001 - `src/cleveragents/config/settings.py` — missing field ## Fix Direction Add `testing_use_mock_ai` as a `Settings` field and update all call sites: ```python # src/cleveragents/config/settings.py testing_use_mock_ai: bool = Field( default=False, validation_alias=AliasChoices("CLEVERAGENTS_TESTING_USE_MOCK_AI"), description=( "When True, use mock AI providers instead of real LLM backends.
