fix beta model access

Context

This PR implements a backend-driven gating system for beta models, specifically targeting the axon-code-2-pro model. It ensures that experimental features are only accessible to authorized users while also including UI/UX refinements and tool robustness improvements.

Implementation

Summary By MatterAI

🔄 What Changed

Beta Gating: Implemented fetchBetaModelsRequest in the extension to query api.matterai.so for user eligibility.
Model Filtering: Updated useProviderModels and KiloCode settings to dynamically filter out axon-code-2-pro if beta access is disabled.
State Sync: Added useEffect hooks in App.tsx to trigger beta checks on mount and configuration changes, with a cache-flushing mechanism in ExtensionStateContext.
Tooling: Enhanced fileEditTool to automatically create missing files (from previous context).
UI Refactor: Modernized chat text area and context menus with new SVG icons and improved mention logic (from previous context).

🔍 Impact of the Change

Feature Control: Enables server-side control over high-resource or experimental models.
Reliability: Reduces user friction by auto-creating files during edits and ensuring the UI state matches backend permissions.
Performance: Optimized model list rendering and cache management during provider switches.

File	ChangeLog
`webviewMessageHandler.ts`	Beta Handler: Added axios-based fetch for beta model status.
`App.tsx`	Lifecycle Hooks: Added effects to refresh beta status on config change.
`ExtensionStateContext.tsx`	State Management: Handles response and flushes router cache.
`KiloCode.tsx`	UI Filtering: Filters model picker based on beta status.
`useProviderModels.ts`	Logic Filter: Prevents unauthorized model selection in hooks.
`prettyModelName.ts`	Metadata: Added display name for `axon-code-2-pro`.
`package.json`	Version: Bumped to 5.3.3.

🧪 Test Added/Recommended

Added

Updated command-autocomplete.spec.ts and context-mentions.spec.ts for UI consistency.

🔒 Security Vulnerabilities

Token Exposure: Ensure kilocodeToken is only transmitted over HTTPS to api.matterai.so.
Input Validation: Validate the structure of the response from the beta models endpoint before spreading into state.

How to Test

Open settings and configure a valid KiloCode token.
Verify Axon Code 2 Pro appears in the model list only if the backend returns enabled: true.
Switch API organizations and confirm the beta status refreshes after the 500ms debounce.

🧪 PR Review is completed: Review of beta models gating implementation. Identified redundant effect hooks in App.tsx causing double requests and a potential logic issue in state context regarding default values.

webview-ui/src/App.tsx

+	// kilocode_change start: Fetch beta models availability on mount and when API config changes
 	useEffect(() => {
 		if (didHydrateState && apiConfiguration?.kilocodeToken) {
 			vscode.postMessage({ type: "fetchBetaModelsRequest" })
 		}
 	}, [didHydrateState, apiConfiguration?.kilocodeToken])

+	// Additional effect to refresh beta models when switching between API configurations


🟡 Performance

Issue: Redundant useEffect hooks. The new debounced effect (lines 261-275) duplicates the functionality of the existing effect (lines 255-259) regarding kilocodeToken changes. Having both active causes double network requests (one immediate, one delayed) and potential race conditions.

Fix: Remove the old immediate effect and the "Additional" qualifier from the new effect's comment, relying solely on the new debounced implementation.

Impact: Prevents duplicate API calls and race conditions.

Suggested change

// kilocode_change start: Fetch beta models availability on mount and when API config changes

useEffect(() => {

if (didHydrateState && apiConfiguration?.kilocodeToken) {

vscode.postMessage({ type: "fetchBetaModelsRequest" })

}

}, [didHydrateState, apiConfiguration?.kilocodeToken])

// Additional effect to refresh beta models when switching between API configurations

-						}))
-					}
+					const payload = message.payload as { enabled?: boolean; success?: boolean }
+					const enabled = payload?.enabled ?? payload?.success ?? false


🟠 Security / Logic

Issue: Insecure default behavior. The fallback ?? payload?.success evaluates to true if enabled is missing or null (assuming the request succeeded). Feature flags should strictly default to false (fail closed) when the status is indeterminate to prevent unauthorized access.

Fix: Remove the fallback to payload.success and default to false if enabled is not explicitly provided.

Impact: Ensures the feature remains disabled if the API response is ambiguous.

Suggested change

const enabled = payload?.enabled ?? payload?.success ?? false

const enabled = payload?.enabled ?? false
