Issue

Closes #1247

Summary

  • Before: Guardrail entries in the config blob could only reference a validator_config_id, and the only way to turn one off was to delete it.
  • Now: Each entry can be either a reference or an inline validator spec (type, on_fail, per-type params). Both kinds take an is_enabled flag (default true).
  • Inline type is limited to InlineValidatorTypeEnum: gender_assumption_bias, pii_remover, profanity_free, topic_relevance_llm.
  • Disabled entries stay saved in the config version but are never fetched or sent to the guardrails service.
  • A blob is either all references or all inline specs. References are fetched from the service as before; inline specs are sent as-is with stage stamped and is_enabled stripped, because the service's validator schemas forbid extra fields. on_fail is passed through, so the service applies its own default when it's omitted.
  • GuardrailEntry is an explicitly tagged union. Without the tag, InlineValidator (which allows extras) could swallow a reference dict that carries a type.

Guardrail entries in the LLM config blob can now be either a validator_config_id reference or an inline validator spec. Both accept is_enabled (default true): disabled entries stay saved in the config version but are never fetched or sent to the guardrails service.

Validators are sent in blob order, inline specs get their stage stamped and is_enabled stripped (the service's validator schemas forbid extras).

📝 Walkthrough

Guardrail configuration now accepts validator references and inline specifications. The service skips disabled entries, fetches configs for enabled references, and prepares the remaining validators for input or output validation.

Changes: Guardrail Configuration and Execution

Layer / File(s) Summary
Define guardrail entry variants
backend/app/models/llm/request.py, backend/app/tests/models/llm/test_request.py
ConfigBlob accepts validator references or inline specifications. Both entry types support is_enabled, which defaults to True. Tests cover parsing, extra fields, unsupported types, and JSON round-trips.
Prepare and validate enabled entries
backend/app/services/llm/guardrails.py, backend/app/tests/services/llm/test_guardrails.py, backend/app/tests/services/llm/test_jobs.py, docs/wiki/modules/llm-call.md
The service skips disabled entries, fetches enabled references, preserves configuration order, assigns the selected stage, and omits is_enabled from serialized validator specs. Tests cover no-op cases, missing references, inline validators, input validation, and output validation. Documentation describes the updated guardrail schema and preparation behavior.

The change adds inline guardrail validators and enabled flags. Formatting the service file and fixing the documentation inconsistency should be done before merge. No functional defect has been established.

The guardrail model, service logic, tests, and guardrail documentation support issue #1247. The same documentation change also changes prompt_template interpolation to say that {{input}} is llm-chain-only. Issue #1247 does not request this behavior or documentation change, and the reviewed changes provide no related implementation or tests.

Optional: use enum.StrEnum.

Ruff flags InlineValidatorTypeEnum (UP042) for inheriting from both str and Enum. StrEnum is available because the project requires Python 3.12 or later. The change does not alter JSON serialization. It is a low-value style fix.

## Key pydantic/SQLModel schemas (`models/llm/request.py`)
- `LLMCallConfig` — one-of: saved reference (`id` + `version`) XOR ad-hoc `blob` (validator-enforced)
- `ConfigBlob` — `completion` + optional `prompt_template` (`PromptTemplate.template`, plain string) + `input_guardrails`/`output_guardrails`
- `ConfigBlob` — `completion` + optional `prompt_template` (`PromptTemplate.template`, plain string; `{{input}}` interpolation is llm-chain-only) + `input_guardrails`/`output_guardrails`. Each guardrail entry is either a `Validator` reference (`{validator_config_id}`) or an `InlineValidator` spec (`{type, on_fail, ...per-type params}`, `type` limited to `InlineValidatorTypeEnum`: gender_assumption_bias, pii_remover, profanity_free, topic_relevance_llm); tagged union `GuardrailEntry`. Both carry `is_enabled` (default true). Disabled entries are never fetched or sent. `services/llm/guardrails._prepare_validators` POSTs the rest in blob order, with `is_enabled` stripped and `stage` stamped on inline specs.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Remove the "{{input}} interpolation is llm-chain-only" claim. It contradicts the Gotchas section.

Line 30 now says that {{input}} interpolation is llm-chain-only. Line 54 says the opposite in bold: execute_llm_call replaces {{input}} for every caller. The two statements disagree. A reader who trusts Line 30 can set prompt_template on a non-chain call and assume nothing happens. Line 54 warns that this silently drops the user input. Restore the earlier wording on Line 30, or point to the Gotcha.

📝 Proposed fix
-- `ConfigBlob` — `completion` + optional `prompt_template` (`PromptTemplate.template`, plain string; `{{input}}` interpolation is llm-chain-only) + `input_guardrails`/`output_guardrails`.
+- `ConfigBlob` — `completion` + optional `prompt_template` (`PromptTemplate.template`, plain string; `{{input}}` is interpolated for every caller — see Gotchas) + `input_guardrails`/`output_guardrails`.

…config ids

Validator rows fetched upstream are now matched by id in _prepare_validators,
so tests merged from main whose mock rows lacked an id silently resolved to
a no-op outcome.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Blobs are either all config-id references or all inline specs, so
apply_guardrails sends fetched rows plus inline specs as-is instead of
matching rows back to requested ids. Restores the pre-branch mock shape
in tests that only exercise reference validators.

…d them to Kaapi (#5885)

## Summary

Closes #5886 (epic #5367)

- **Before:** Glific had no way to attach guardrails to an assistant.
The Kaapi config blob never carried `input_guardrails` /
`output_guardrails`, so Kaapi ran no validators on assistant LLM calls.
- **Now:** `createAssistant` / `updateAssistant` accept
`input_guardrails` and `output_guardrails` (JSON lists of inline
validator specs, same contract as Kaapi PR
ProjectTech4DevAI/kaapi-backend#1245). Glific stores them on the
assistant config version and sends them in the Kaapi config blob, so
Kaapi runs them on every LLM call for that assistant.

### Changes

-
`priv/repo/migrations/…_add_guardrails_to_assistant_config_versions.exs`:
two `NOT NULL` jsonb columns, default `[]`.
- `Glific.Assistants.AssistantConfigVersion`: `input_guardrails` /
`output_guardrails` as `{:array, :map}`; changeset rejects any entry
without a non-empty `"type"`. Per-type params are validated by Kaapi.
- `Glific.Assistants`: guardrails flow through create, update (new draft
version, no-change detection), deferred Kaapi config, promote-to-major,
legacy shape and version listings.
- `Glific.ThirdParty.Kaapi.build_config_blob/3`: blob always carries
both keys.
- `Glific.ThirdParty.Kaapi.AssistantCloneWorker`: cloned versions keep
their guardrails.
- GraphQL: `input_guardrails` / `output_guardrails` (`:json`) on
`assistant_input`, `assistant`, `assistant_config_version`,
`assistant_config_version_for_evals`; `.gql` assets updated.

### Example input

```json
{
  "input_guardrails": "[{\"type\": \"pii_remover\"}, {\"type\": \"topic_relevance_llm\", \"on_fail\": \"rephrase\", \"configuration\": \"politics, elections\", \"fallback_message\": \"I can only help with farming questions.\"}]",
  "output_guardrails": "[{\"type\": \"gender_assumption_bias\"}]"
}
```

## Checklist

- [x] Ran `mix setup` in the repository root and test.
- [x] If you've fixed a bug or added code that is tested and has test
cases.
- [ ] In the case of adding a new API, you added a **postman** request
for that.
- [x] Coding standard and conventions are followed.

## Notes

- Guardrail fields are `:json` scalars holding a JSON-encoded list, same
contract as `settings`.
- Kaapi already accepts `input_guardrails` / `output_guardrails` on the
config blob and skips when empty, so sending `[]` is safe before
ProjectTech4DevAI/kaapi-backend#1245 merges. Inline (non-reference)
specs only run once that PR is in.
- Not gated on `is_ai_guardrail_enabled`; saving is harmless without the
flag, and gating belongs with the frontend rollout.
- `priv/repo/structure.sql` not regenerated (local pg 14 dump vs
committed pg 15 produces noise); #5871 did the same.
- Tests: 288 passing across assistants, Kaapi client, clone worker and
GraphQL schema.
