Follow the guide to enable codebase context checks.

Objective: Ensure all identifiers clearly express their purpose and intent, making code
self-documenting

Status: Passed

Learn more about managing compliance generic rules or creating your own custom rules

Objective: Ensure comprehensive error handling that provides meaningful context and graceful
degradation

Status:
Missing error handling: The tokenization request failure path only logs the error and resets totalDataCount
without setting UI error state (e.g., isError/errorText) or providing actionable context
to the user.

function getTokenizeResult() {
    return new Promise((resolve, reject) => {
        const request = {
            text: util.trim(text),
            provider: selectedTokenizer,
            options: {
                data_providers: selectedDataLoaders?.length > 0 ? selectedDataLoaders : null
            }
        };

        tokenize(request).then(res => {
            items = res?.results || [];
            totalDataCount = items.length;
            resolve(res);
        }).catch(err => {
            totalDataCount = null;
            console.log(err);
            reject(err);
        });
    });

Objective: To ensure logs are useful for debugging and auditing without exposing sensitive
information like PII, PHI, or cardholder data.

Status:
Insecure console logging: The new code logs raw errors using console.log(err), which is unstructured and may leak
sensitive request/context data in client-accessible logs.

}).catch(err => {
    totalDataCount = null;
    console.log(err);
    reject(err);
});

Objective: To create a detailed and reliable record of critical system actions for security analysis
and compliance.

Status:
No audit logging: The new tokenization-related actions (getTokenizers, getTokenizerDataLoaders, tokenize) do
not show any audit logging and it is not verifiable from the diff whether the backend
records user/action context for these operations.

export async function getTokenizers() {
    const url = endpoints.tokenizersUrl;
    const response = await axios.get(url);
    return response.data;
}

/**
 * @returns {Promise<string[]>}
 */
export async function getTokenizerDataLoaders() {
    const url = endpoints.tokenizerDataLoadersUrl;
    const response = await axios.get(url);
    return response.data;
}

/**
 * @param {import('$knowledgeTypes').TokenizeRequest} request
 * @returns {Promise<import('$knowledgeTypes').TokenizeResponse>}
 */
export async function tokenize(request) {
    const url = endpoints.tokenizeUrl;

Learn more about managing compliance generic rules or creating your own custom rules

Objective: To prevent the leakage of sensitive system information through error messages while
providing sufficient detail for internal debugging.

Status:
Error details exposed: Client-side console.log(err) may expose internal error details to end-users via browser
console, and it is unclear whether err contains sensitive backend information.

}).catch(err => {
    totalDataCount = null;
    console.log(err);
    reject(err);
});

Objective: Ensure all data inputs are validated, sanitized, and handled securely to prevent
vulnerabilities

Status:
Input validation unclear: The new tokenize API call forwards user-controlled request fields directly to the backend
and the diff does not show server-side validation/authz controls, so secure handling
cannot be confirmed from this change alone.

/**
 * @param {import('$knowledgeTypes').TokenizeRequest} request

Add a check to ensure item[detailKey] is a non-null object before using
Object.keys() to prevent incorrect rendering when the value is a primitive type.

src/routes/page/knowledge-base/common/table/table-item.svelte [105-112]

 {:else}
-    {#each Object.keys(item[detailKey]) as key, idx (idx)}

-            <span>{item[detailKey][key]}</span>

The new table-item.svelte component is reusable but located in a
feature-specific directory. It should be moved to a shared location like
src/lib/components/ to improve discoverability and project structure.

Examples:

<script>
    import { Button } from "@sveltestrap/sveltestrap";
    import { fly } from 'svelte/transition';
	import Loader from "$lib/common/Loader.svelte";
    import JSONTree from 'svelte-json-tree';
	import { formatObject, splitTextByCase } from "$lib/helpers/utils/common";

    /** @type {any} */
    export let item;

Solution Walkthrough:

Before:

src/
└── routes/
    └── page/
        └── knowledge-base/
            ├── common/
            │   └── table/
            │       └── table-item.svelte  # Reusable component
            └── dictionary/
                └── +page.svelte           # Uses table-item.svelte

After:

src/
├── lib/
│   └── components/              # Or another shared directory
│       └── table-item.svelte    # Reusable component moved here
└── routes/
    └── page/
        └── knowledge-base/
            └── dictionary/
                └── +page.svelte   # Now imports from /lib/components

In the catch block of getTokenizerProviders, simplify the state reset by setting
selectedTokenizer directly to null instead of deriving undefined from an empty
tokenizers array.

src/routes/page/knowledge-base/dictionary/+page.svelte [140-153]

 function getTokenizerProviders() {
 		return new Promise((resolve, reject) => {
 			getTokenizers().then(res => {
 				const retProviders = res?.map(x => ({  label: x, value: x })) || [];
 				tokenizers = [ ...retProviders ];
 				selectedTokenizer = tokenizers[0]?.value;
 				resolve(res);
 			}).catch(err => {
 				tokenizers = [];
-				selectedTokenizer = tokenizers[0]?.value;
+				selectedTokenizer = null;
 				reject(err);
 			});
 		});
 	}
