21-24: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winAdd a server-enforced bound to the list read.
list_guardrail_credentialsselects every row, and the operator list route returns all of them. The table is operator-authored and normally small, so the practical risk today is low. The repository guideline is explicit, though, and a cheap cap here keeps the endpoint from growing into an unbounded read later.Consider accepting a
limit(with a default maximum) and applying it in SQL.♻️ Possible shape
-async def list_guardrail_credentials(db: AsyncSession) -> list[GuardrailCredential]: - """Every stored guardrail, ordered by name.""" - rows = (await db.execute(select(GuardrailCredential).order_by(GuardrailCredential.name))).scalars().all() - return list(rows) +async def list_guardrail_credentials(db: AsyncSession, *, limit: int = 500) -> list[GuardrailCredential]: + """Stored guardrails, ordered by name, bounded by ``limit``.""" + stmt = select(GuardrailCredential).order_by(GuardrailCredential.name).limit(limit) + return list((await db.execute(stmt)).scalars().all())As per coding guidelines: "Every list endpoint has a server-enforced limit, including operator endpoints."

Second pass, on the three findings from the latest review. The PATCH example. Fixed, at its source rather than in the collection. The collection is generated from {"create_kwargs": {"api_key": "***", "endpoint": "https://api.lakera.ai/v2/guard"}, "enabled": false}A true partial update, no The re-encryption pass, both findings. Real, and both left alone here on purpose. They are #1127, which predates this branch and names the pattern rather than the copy: Changing it in one store leaves three stores with two shapes, which is worse than three with one flawed shape: the next person copies whichever they find first. So I have added both dimensions to #1127 instead of opening a fourth issue, since the fix wants one loop: #1127 (comment) The two are also the same rewrite. A conditional update matching the ciphertext that was read has to happen per row, and doing that over a keyset batch is the bounded read. Splitting them would mean touching the same function in three stores twice. Worth recording while it is in view: this store does not inherit the other half of #1127. It owns its commits and turns an Also from the first pass: #1212 bounds the ordinary list reads of the two older stores, and #1213 covers stored guardrail URLs getting no |

Process re-encryption in bounded batches.
repository.list_encrypted_guardrail_credentials materializes every encrypted credential. reencrypt_guardrail_credentials retains that result while processing each row and commits only after the full pass. As the table grows, memory use and transaction duration grow without bound, so credential rotation can fail before completion.
Use stable keyset batches for lookup and updates. Keep only one batch in memory, release each batch after processing, and preserve the service-owned transaction and rollback contract.

The service does not roll back that failure, and the route's SQLAlchemyError handler raises the database error without rolling back. get_db closes the session only after the handler exits, so its lifecycle does not replace the service-owned rollback required by the project contract.
Proposed fix
try:
await repository.add_guardrail_credential(db, row)
await _commit(db)
except IntegrityError:
await db.rollback()
raise GuardrailCredentialExistsError(name) from None
+ except SQLAlchemyError:
+ await db.rollback()
+ raise🤖 Prompt for AI Agents

Fifth pass. The flush window. Right, and it was a gap I opened last round. When I moved the rollback into the service I wrapped the commit alone, but Fixed by widening the block rather than adding a second handler. async with _write(db):
await repository.add_guardrail_credential(db, row)
await db.commit()One rollback site per write, and it covers both windows. The Two tests: one patches Bounded batches for re-encryption. Same finding as the earlier thread, and still deferred to the same place. It is #1127, which describes the shape rather than this copy: the provider and search-tool stores read every encrypted row the same way. I added the batching scope to that issue after the earlier round, so it is recorded rather than dropped: #1127 (comment) The reasoning has not changed. The conditional update that issue already asks for has to happen per row, and doing that over a keyset batch is the same loop, so splitting them would mean touching the same function in three stores twice. Changing it in one store also leaves three stores with two shapes, and the next person copies whichever they find first.

A guardrail profile is a key in a YAML file inside the guardrails container today, so defining one means editing that file and restarting it. This table holds the definition instead: the any_guardrail class the catalog offered, plus the arguments that build and call it, named by the profile a caller sends. The constructor arguments take two columns rather than one each. The guardrails a hosted API reaches carry between zero and three secret arguments, so a column per credential would chase every guardrail upstream adds; the non-secret ones stay plain and every secret goes into one map encrypted as a single string. Nothing reads the table yet. Refs #1209 Signed-off-by: Dimitris Poulopoulos <dimitris@mozilla.ai>
The error family and the session access for guardrail_credentials, both leaves with no logic of their own. Every error names a rule the guardrail catalog states rather than one written here, so the store can only refuse what the picker would not have offered. They carry no status_code: that convention belongs to the tenancy slice, where one registered handler serves a family too large to wrap per route, and this family has a single caller that maps it the way the search-tool routes map theirs. The repository flushes and never commits, leaving the commit boundary with the service. Refs #1209 Signed-off-by: Dimitris Poulopoulos <dimitris@mozilla.ai>
The service behind the store: hold a submitted definition to what the catalog says its guardrail accepts, split the secrets out by the catalog's own flag, and encrypt them as one map. Every rule is read off the catalog rather than written here, so the store is wrong exactly when the picker is. A list of names, of required arguments or of which arguments are credentials could only drift from the form it exists to accept, and the drift would show as a field the form offers and the store refuses. Two rules need a carve-out. A required argument that names an environment variable may be omitted, because the catalog folds upstream's effectively-required flag into required and demanding it would refuse a working row; a requirement group that names one is skipped for the same reason. Neither consults the environment, since whether a variable is set belongs to the process that builds the guardrail and not to the one writing the row. Adds builtin_guardrail_spec to the catalog so the store looks a guardrail up instead of reaching for a private helper. Refs #1209 Signed-off-by: Dimitris Poulopoulos <dimitris@mozilla.ai>
The route in. /api/v1/guardrail-credentials is the write target for the picker at GET /api/v1/tool-settings/guardrails/catalog, so a guardrail chosen there can be filled in and saved. Deliberately the shape of /api/v1/search-tools and /api/v1/provider-credentials: rows keyed by name, credentials encrypted at rest and never returned, a tri-state PATCH under a row lock with an optimistic-concurrency check, and a re-encryption endpoint for OTARI_SECRET_KEY rotation. Operator-gated, and the hybrid stub answers the prefix with the reason rather than a bare 404. Where it parts company with those two is the response. A guardrail may hold several credentials, so the row reports which ones are set by name and each masked, rather than the last four characters of a single key. A row whose map cannot be read is listed with no names and decryptable false, because the operator is the one person who can fix it. Refs #1209 Signed-off-by: Dimitris Poulopoulos <dimitris@mozilla.ai>
Says how a choice from the catalog is saved: one create_kwargs map that Otari splits by the catalog's secret flag, a response that names the stored credentials without carrying one, what the mask means on a PATCH, the four refusals and why a live object is one of them, and what decryptable false asks an operator to do.

Fine for me. There are some comments to be addressed, though, but I'll probably be fine with whatever solution we agree, so pre-approved.
I'd create (as part of another PR) a separate root for all these operations, like /management/v1. This is an api, of course, but not a user-facing API. I'd also prefer to see a separate package for management deployed in its own container for further security and deploy flexibility.

I'd use a specific object, like {"masked": null} or value 0 (value null probably means something else already).

Description
#1160, the branch this targets, gave the dashboard a picker.
GET /api/v1/tool-settings/guardrails/cataloglists the guardrails any-guardrail reaches over a hosted API and, for each one, the constructor and per-call arguments it takes, which of them are credentials, and which cannot be written down at all.This is the write target. A
guardrail_credentialsrow names the guardrail, carries the arguments that build and call it, and is itself named by theprofilea caller sends. Nothing on the request path reads it yet.Secrets are one encrypted map, not columns
The ten guardrails do not share a secret shape. For example,
bedrock_guardrailstakes three secrets in its constructor,watsonx_guardiantakes two, and another guardrail we add tomorrow may need four. So the client sends onecreate_kwargsmap and the service splits it by the catalog's ownsecretflag: the plain half is stored as it is, and every secret goes into a single{name: value}map encrypted as one string. That needs no per-guardrail knowledge here.Five rules, none of them a list kept in this repository
guardrail_namemust be onebuild_builtin_guardrail_catalog()lists.storable=Falseargument is refused.required=Trueconstructor argument that names noenv_varmust be supplied.env_varsof its own is refused.How to test it locally
Expect the identifier and region back under
create_kwargs, the two AWS keys only ascreate_secrets: {"aws_access_key_id": "***", "aws_secret_access_key": "***"}, anddecryptable: true. Then confirm the split reached the database rather than only the response:create_kwargsholds the three plain values, andleaks_keyis false: the column is a Fernet token. Worth trying the two refusals as well,boto3_sessionand a missingguardrail_identifier, each a 400 naming the rule.PR Type

Adjacent and deliberately not fixed here: #1125 (

feat-hosted-guardrail-catalograther thanmain, because the store validates against a catalog that only lists the ten hosted-API guardrails on that branch. The unresolved review on #1160 asking for six more guardrails resolves upstream of this work: the store reads the catalog function rather than a frozen list, so it follows whatever that branch decides with no edit here.AI Usage
