source = "victoria_logs" is not a valid EvidenceSource value (see app/types/evidence.py). Because BaseTool.__init_subclass__() validates metadata at import time, this will raise during module import and prevent the tool registry from loading. Add "victoria_logs" to the EvidenceSource Literal (or change this tool's source to an existing value if that's intended).

extract_params() returns {}, but the investigation executor calls action.run(**action.extract_params(...)). That means run() will be invoked without the required query argument and will raise a TypeError. Implement extract_params() to supply at least query/limit/start (and any needed connection params), and update run() to accept those explicitly rather than relying on kwargs["sources"] which will never be passed by the executor.

tenant_id defaults to the string "0", which is truthy, so this client will always send an AccountID: 0 header. If "0" is intended to mean “no tenant scoping” (as implied elsewhere in the codebase), consider only setting this header when tenant_id is non-empty and not "0" to avoid unintended scoping or auth failures.

The NDJSON parsing loop silently ignores JSON decoding failures (except Exception: pass). This can turn partial/invalid responses into “success” with missing rows and no signal to callers. Catch json.JSONDecodeError explicitly and return a warning/error (e.g., include a parse_errors count or fail the request if any non-empty line is invalid).

Extra field integration_id breaks DB-configured Victoria Logs

VictoriaLogsIntegrationConfig extends StrictConfigModel which sets extra="forbid". Passing integration_id to model_validate() will always raise a ValidationError, which is silently swallowed by the surrounding except Exception: continue. This means any Victoria Logs integration stored in the database will be permanently skipped — only env-var-backed (VICTORIA_LOGS_BASE_URL) configurations will work.

**Extra field `integration_id` breaks DB-configured Victoria Logs**

`VictoriaLogsIntegrationConfig` extends `StrictConfigModel` which sets `extra="forbid"`. Passing `integration_id` to `model_validate()` will always raise a `ValidationError`, which is silently swallowed by the surrounding `except Exception: continue`. This means any Victoria Logs integration stored in the database will be permanently skipped — only env-var-backed (`VICTORIA_LOGS_BASE_URL`) configurations will work.

```suggestion
                victoria_logs_config = VictoriaLogsIntegrationConfig.model_validate(
                    {
                        "base_url": credentials.get("base_url", ""),
                        "tenant_id": credentials.get("tenant_id", "0"),
                    }
                )
```

victoria_logs missing from EffectiveIntegrations

EffectiveIntegrations also extends StrictConfigModel (extra="forbid"). Any code that hydrates this model from the resolved integrations dict will raise a ValidationError if victoria_logs is present. All other integrations (grafana, datadog, coralogix, alertmanager, etc.) have a corresponding field here; victoria_logs needs one too.

import contextlib inside the loop

Module imports should be at the top of the file, not inside a for loop. Python caches them so it won't crash, but it's non-idiomatic and obscures intent. Move the import to the module level alongside the other imports.

Then remove the in-loop import and keep only with contextlib.suppress(Exception):.

alert_source description omits victoria_logs

All other log/observability integrations added to the platform are listed in this field's description to guide the LLM. The extract prompt in extract.py also enumerates them explicitly. If VictoriaLogs can be the origin of an alert (e.g. alerting rules inside VictoriaLogs), the LLM will have no hint to set alert_source = "victoria_logs". Consider adding it to the allowed set if applicable.

These prompt changes (CRITICAL RCA BEHAVIORS block and the general chat rewrite) have nothing to do with Victoria Logs. Please remove them from this PR. If you think they're worth making, open a separate PR for them.

VictoriaLogsIntegrationConfig is imported in verify.py, the service init, and the tool — but it's never actually defined anywhere in this PR or in main. This will throw an ImportError the moment any of those modules are loaded. You need to add the Pydantic model class here, something like:\n\npython\nclass VictoriaLogsIntegrationConfig(StrictConfigModel):\n base_url: str = ""\n tenant_id: str = "0"\n integration_id: str = ""\n

This import will crash at load time because VictoriaLogsIntegrationConfig doesn't exist in models.py. Fix the model definition first (see comment on models.py).

The verify function itself looks fine, but it won't actually get called. For victoria_logs to appear in effective_integrations, catalog.py needs a classification block for it (similar to how other services are handled in _classify_service_instance). Without that, the config will never reach here. Please also add load_env_integrations() support with env vars like VICTORIA_LOGS_URL and VICTORIA_LOGS_TENANT_ID.

These changes to alert_source routing and the new CRITICAL INSTRUCTIONS block are not related to Victoria Logs at all. Please remove them from this PR — they change core routing behaviour and would need their own review and tests.
