Reject whitespace-only requestTransforms entries in both load-time schemas.
z.string().min(1) accepts " ", and normalizeNonBlankStringArray converts it to [""]. The request-transform runner then filters the empty entry, so disk-loaded configuration silently disables that transform. The management API rejects the same value through requestTransformsConfigError. Use z.string().trim().min(1) at src/config.ts:587-589 and src/config.ts:1141-1143. Add global- and provider-scope tests for [" "].

Rebind the turn-termination scope after request transforms
At src/transforms/runner.ts:144, replacement transforms create a new request object. The spread preserves _reasoningReplayScope because it is a shared holder reference, so replay-scope binding remains valid.
The turn-termination scope is different. src/responses/turn-termination.ts:12 stores scopes in WeakMap<OcxParsedRequest, string>. bindTurnTerminationScope binds the pre-transform object at src/server/responses/core.ts:3223, but later lookups use the transformed object. Rebind the scope after applyRequestTransforms returns. Otherwise, Kiro final-answer tracking and trailing-answer detection silently miss replacement requests.

Bound the per-row re-parse cost before long conversations.
When the existing prefix changes, src/transforms/responses-body.ts:70-80 enters the fallback loop and calls parseRequest for each source unit. parseRequest validates and traverses each synthetic request, while lines 83, 96, and 100-104 perform additional JSON serialization and parsing during matching. A long continuation can therefore spend significant request-thread time on repeated parsing and serialization before forwarding the request.
Memoize the projection for each exact rows unit, or compute projections lazily for the lengths that the matcher probes. Add a benchmark or focused test for a large continuation body before merge.

Security Misconfiguration (CWE-94): Improper Control of Generation of Code ('Code Injection')
Reachability: External · Exploitability: Difficult
Do not expose requestTransforms through admin-token management routes.
The management API accepts the configured admin token, and provider POST, PATCH, and PUT routes are not gui-session-only. A non-loopback deployment can therefore let a remote admin-token holder persist requestTransforms. src/transforms/runner.ts executes those values with await import() without an allowlist or sandbox.
Gate this field behind a local-only trusted capability, or allow only modules from a pre-approved directory or package set. Do not treat the general admin token as equivalent to filesystem access to the proxy configuration.

Preserve an omitted previousResponseId in the replacement merge. RequestTransformFn permits a complete canonical replacement, and the spread already preserves other proxy-owned fields that the replacement omits. At src/transforms/runner.ts:144, the trailing assignment unconditionally writes result.previousResponseId, so a valid replacement without that key clears the resolved continuation ID. Use an own-property check so an omitted key preserves the current ID while an explicit value, including an explicit clear, takes effect. Extend tests/usage/request-transforms.test.ts:119 with previous_response_id and assert that the ID survives the minimal replacement.

Validate in-place mutations before synchronizing the response body
A configured RequestTransformFn may mutate currentParsed and return void. This path skips isValidParsedRequest. If the transform sets context or options to an invalid value, syncTransformedResponsesBody dereferences it at src/transforms/responses-body.ts:174-232 after the per-transform try block in src/transforms/runner.ts:140-154. The resulting TypeError rejects applyRequestTransforms at src/server/responses/core.ts:3609, so request processing stops instead of warning and continuing.
Snapshot the last valid request before each transform. Validate currentParsed after every transform, including void returns. Restore the snapshot when validation fails, and contain synchronization failures within the same warning-and-continue boundary.

Expose a deep-readonly transform context.
src/server/index.ts:652-665 captures one config object for the server lifetime. src/transforms/runner.ts:124-140 passes that object and the selected provider configuration to each handler. The documented contract in docs-site/src/content/docs/reference/configuration.md:51-54 describes request mutation, but src/transforms/types.ts:9-11 also exposes mutable configuration objects. A handler can change config.providers or provider fields, and later requests can use those changes. Expose a deep-readonly projection or a deep-frozen snapshot. A shallow Readonly type does not protect nested values.

type around providerConfig and config to expose a deep-readonly projection, and
ensure the runtime context passed by the transform runner prevents nested
mutation of both configuration objects. Preserve request mutability while
preventing handlers from changing config.providers or provider fields across

Add a previousResponseId assertion to this replacement test.
Line 119 proves that _previousResponseInputExpanded survives a complete replacement. previousResponseId is not checked, and that is the one proxy-owned field the merge on src/transforms/runner.ts Line 144 overwrites unconditionally. The fixture on Lines 103-106 returns the minimal valid shape without that key, so it reproduces the loss — the test simply never looks.
Set a previous_response_id on the request built at Line 111 and assert it survives. See the root-cause comment on src/transforms/runner.ts Line 144 for the fix.

Assert the exact acceptsImageInput value.
tests/usage/request-transforms.test.ts:244 checks only the transform marker. Because src/transforms/runner.ts:114-121 converts lookup errors to false, the test can pass while isVisionEligibleModel fails. Use a model with a known vision verdict and assert the complete rendered message:

Summary
Closes #3459.
Adds opt-in
requestTransformsafter final routing/normalization and before input admission and adapter dispatch. Global handlers run before provider handlers; each receives the normalized request, settled provider/model, andacceptsImageInput. Model-specific behavior branches onmodelIdinside the handler.Handlers may mutate in place or return a complete canonical replacement. Replacements retain proxy-owned authentication/replay metadata. Changed messages, tools, system prompts and generation options are synchronized into native Responses bodies while retaining unchanged native items and provider-specific fields. Tool bridge maps are built once after transforms, so outbound tool declarations and restored response aliases use the transformed catalog without double-charging the translator budget.
The hook runs once per parsed request reused by internal retries. New inbound requests run it again, including requests replaying earlier history; handlers editing history must recognize their own output. The public configuration documentation states this boundary.
Current head:
fc3075f27, based ondevatece556a6e. All four original CodeRabbit findings are addressed, including native message/tool integration coverage. A repeated-message regression verifies that editing one duplicate retains each native message's own metadata.Maintainer security review requested
The remaining upstream gate is
maintainer-sponsored: provider management validation inauth-cors.tsand the dynamic-import extension require a maintainer's explicit security review. The proposed loading contract supports trusted local files and installed module/package specifiers, with no dependency-installation step. The feature is off by default; handlers run with the proxy's permissions and configuration access. Imports are cached. Load/execution failures warn and continue, and mutations before a thrown error are not rolled back.Please review that loading/failure contract and the management configuration surface, apply sponsorship if accepted, and approve the contributor workflows. The author has not applied the sponsorship label or approved their own work. Both maintainers are already assigned as reviewers.
