-            ## Role
-
-            You are an issue triage assistant. Your role is to analyze a GitHub
-            issue and identify appropriate labels based on the definitions
-            provided.
-
-            ## Steps
-            1. Check environment variable for issues to triage: $ISSUES_TO_TRIAGE (JSON array of issues).
-            2. Review the available labels: ${{ env.AVAILABLE_LABELS }}.
-            3. Identify the most relevant labels from the existing labels,
-            focusing on 'priority: *', 'type: *', and 'product: *'.
-            4. If the issue already has a 'product: *' label, do not try to
-            change it. If the issue already has a 'type: *' label, do not try to
-            change it. If the issue already has a 'priority: *' label, do not
-            try to change it. For example, if an issue already has a 'product:
-            *' label, you wil only add a 'type: *' and/or 'priority: *' label.
-            Instead, if an issue has no labels, you could add one labels of each
-            kind.
-            5. Fallback Logic:
-                - If you cannot confidently determine the correct 'product: *' label
-                from the definitions, feel free to leave it.
-                - If you cannot confidently determine the correct 'type: *' label
-                from the definitions, feel free to leave it.
-                - If you cannot confidently determine the correct 'priority: *'
-                label from the definitions, apply the 'status: manual-triage'
-                label.
-            6. Give me a single short explanation about why you are selecting
-            each label in the process.
-            7. Output a JSON array of objects, each containing the issue number
-               and the labels to add and remove, along with an explanation and
-               nothing else. Example:
-               ```
-               [
-                 {
-                   "issue_number": 123,
-                   "labels_to_add": ["product: alloydb", "priority: p2"],
-                   "labels_to_remove": ["status: need-triage"],
-                   "explanation": "This issue is a bug within the alloydb tool that needs to be addressed with medium priority."
-                 }
-               ]
-               ```
-            8. If you see that the issue doesn't look like it has sufficient
-            information, leave a comment politely requesting the relevant
-            information.
-              - After identifying appropriate labels to an issue, add "status:
-              need-triage" label to labels_to_remove in the output.
-            10. If you think an issue might be a 'priority: p0' do not apply the
-            'priority: p0' label. Instead, apply a 'status: manual-triage' label
-            and include a note in your explanation.
-

-            - Your output must contain exactly one priority: label.
-            - Output only valid JSON format.
-            - Do not include any explanation or additional text, just the JSON.
-            - Only use labels that already exist in the repository.
-              - Do not add comments or modify the issue content.
-              - Triage only the current issue.
-              - Identify only one 'product: *' label
-              - Identify applicable 'priority: *' labels based on the issue content.
-              - Once you categorize the issue if it needs information, bump down the priority by 1 eg.. a p0 would become a p1 a p1 would become a p2. P2 and P3 can stay as is in this scenario.
-
-            Guidelines for Priority labels
-            'priority: p0': Critical / Blocker
-            - Definition: A catastrophic failure that makes the server unusable for most users or poses a severe security risk. This includes installation failures, authentication failures, persistent crashes, or critical security vulnerabilities.
-            - Key Questions:
-              - Is the main goal of the tool (e.g., connecting an agent to a database) completely impossible?
-              - Is the server failing to install or run?
-              - Does this represent a critical security vulnerability?
-              - Does this block existing user and have to be resolved immediately in order to utilize the server again?
-              - Does this issue affect every user immediately upon running the latest version?
-              - Is there absolutely no temporary workaround or alternative method to achieve the desired result?
-
-            'priority: p1': High
-            - Definition: A severe issue that causes a significant degradation of a key feature, produces incorrect or inconsistent results, or severely impacts a large number of users. It requires prompt resolution, though a temporary workaround might exist. This also includes critical missing documentation for core features.
-            - Key Questions:
-              - Does this issue affect a key component that is widely relied upon (e.g., core database operations)?
-              - Are the results produced by the tool incorrect, misleading, or unreliable?
-              - Is a feature failing for a specific, large user group (e.g., all Windows users, all users of a specific shell)?
-              - Does a user need to perform difficult, undocumented steps to work around the problem?
-              - Is essential setup or usage documentation completely missing for a new feature?
-
-            'priority: p2': Medium
-            - Definition: A moderately impactful issue causing inconvenience or a non-optimal experience, but a reasonable workaround exists. This also includes failures in non-core features. 
-            - Key Questions:
-              - Is the issue a standard bug fix that only affects a smaller, non-critical area of the code?
-              - Is this a clear, actionable enhancement that adds tangible value without being mission-critical?
-              - Can the user easily and reliably work around the issue without major difficulty?
-              - Is this an overdue technical debt item or a minor documentation correction?
-
-            'priority: p3': Low
-            - Definition: A minor, low-impact issue with minimal effect on functionality. This includes most cosmetic defects, typos in documentation, or unclear help text. They have minimal to no impact on the current functionality or user experience and can be addressed when time and resources allow.
-            - Key Questions:
-              - Is this a typo in the README.md, gemini --help text, or other documentation?
-              - Is this a minor cosmetic issue (e.g., text alignment in output, an extra newline) that doesn't affect usability?
-              - Is the issue a minor cleanup or refactoring that doesn't fix a current problem but improves code style?
-              - Can this be ignored for several release cycles without negatively impacting users?
-
-            Guidelines for Product labels
-            If the issue is specific towards a product, add the product label.
-            For example, alloydb related issue should be assigned the 'product:
-            alloydb' label. The available 'product: *' labels are included in
-            the list of available products.
-
-            Guidelines for Type labels
-            Assign the issue based on type. The available 'type: *' labels are
-            included in the list of available labels.
-            'type: bug'
-            - Error or flaw in code with unintended results or allowing sub-optimal usage patterns.
-            'type: cleanup'
-            - An internal cleanup or hygiene concern.
-            'type: docs'
-            - Improvement to the documentation for an API.
-            'type: feature request'
-            - ‘Nice-to-have’ improvement, new feature or different behavior or design.
-            'type: process'
-            - A process-related concern. May include testing, release, or the like.
-            'type: question'
-            - Request for information or clarification.

+### Link Checking and Fixing with Lychee
+
+We use **[lychee](https://github.com/lycheeverse/lychee-action)** for repository link checks.
+
+* To run the checker **locally**, see the [command-line usage guide](https://github.com/lycheeverse/lychee?tab=readme-ov-file#commandline-usage).
+
+####  Fixing Broken Links
+
+1.  **Update the Link:** Correct the broken URL or update the content where it is used.
+2.  **Ignore the Link:** If you can't fix the link (e.g., due to **external rate-limits** or if it's a **local-only URL**), tell Lychee to **ignore** it.
+
+    * List **regular expressions** or **direct links** in the **[.lycheeignore](https://github.com/googleapis/genai-toolbox/blob/main/.lycheeignore)** file, one entry per line.
+    * **Always add a comment** explaining **why** the link is being skipped to prevent link rot. **Example `.lycheeignore`:**
+       ```text
+       # These are email addresses, not standard web URLs, and usually cause check failures.
+       ^mailto:.*
+       ```
+> [!NOTE]
+> To avoid build failures in GitHub Actions, follow the linking pattern demonstrated here: <br>
+> **Avoid:** (Works in Hugo, breaks Link Checker): `[Read more](docs/setup)` or `[Read more](docs/setup/)` <br>
+> **Reason:** The link checker cannot find a file named "setup" or a directory with that name containing an index. <br>
+> **Preferred:** `[Read more](docs/setup.md)` <br>
+> **Reason:** The GitHub Action finds the physical file. Hugo then uses its internal logic (or render hooks) to resolve this to the correct `/docs/setup/` web URL. <br>

+  EmbeddingModels represent services that transform text into vector embeddings for semantic search.
+---
+
+EmbeddingModels represent services that generate vector representations of text
+data. In the MCP Toolbox, these models enable **Semantic Queries**,
+allowing [Tools](../tools/) to automatically convert human-readable text into
+numerical vectors before using them in a query.
+
+This is primarily used in two scenarios:
+
+- **Vector Ingestion**: Converting a text parameter into a vector string during
+  an `INSERT` operation.
+
+- **Semantic Search**: Converting a natural language query into a vector to
+  perform similarity searches.
+
+## Example
+
+The following configuration defines an embedding model and applies it to
+specific tool parameters.
+
+{{< notice tip >}}
+Use environment variable replacement with the format ${ENV_NAME}
+instead of hardcoding your API keys into the configuration file.
+{{< /notice >}}
+
+### Step 1 - Define an Embedding Model
+
+Define an embedding model in the `embeddingModels` section:
+
+```yaml
+embeddingModels:
+  gemini-model: # Name of the embedding model
+    kind: gemini
+    model: gemini-embedding-001
+    apiKey: ${GOOGLE_API_KEY}
+    dimension: 768
+
+```
+
+### Step 2 - Embed Tool Parameters
+
+Use the defined embedding model, embed your query parameters using the
+`embeddedBy` field. Only string-typed
+parameters can be embedded:
+
+```yaml
+tools:
+  # Vector ingestion tool
+  insert_embedding:
+    kind: postgres-sql
+    source: my-pg-instance
+    statement: |
+      INSERT INTO documents (content, embedding) 
+      VALUES ($1, $2);
+    parameters:
+      - name: content
+        type: string
+      - name: vector_string
+        type: string
+        description: The text to be vectorized and stored.
+        embeddedBy: gemini-model # refers to the name of a defined embedding model
+
+  # Semantic search tool
+  search_embedding:
+    kind: postgres-sql
+    source: my-pg-instance
+    statement: |
+      SELECT id, content, embedding <-> $1 AS distance 
+      FROM documents
+      ORDER BY distance LIMIT 1
+    parameters:
+      - name: semantic_search_string
+        type: string
+        description: The search query that will be converted to a vector.
+        embeddedBy: gemini-model # refers to the name of a defined embedding model

+  Use Google's Gemini models to generate high-performance text embeddings for vector databases.
+---
+
+## About
+
+Google Gemini provides state-of-the-art embedding models that convert text into
+high-dimensional vectors. 
+
+### Authentication
+
+Toolbox uses your [Application Default Credentials
+(ADC)][adc] to authorize with the
+Gemini API client.
+
+Optionally, you can use an [API key][api-key] obtain an API
+Key from the [Google AI Studio][ai-studio].
+
+We recommend using an API key for testing and using application default
+credentials for production.
+
+[adc]: https://cloud.google.com/docs/authentication#adc
+[api-key]: https://ai.google.dev/gemini-api/docs/api-key#api-keys
+[ai-studio]: https://aistudio.google.com/app/apikey
+
+## Behavior
+
+### Automatic Vectorization
+
+When a tool parameter is configured with `embeddedBy: <your-gemini-model-name>`,
+the Toolbox intercepts the raw text input from the client and sends it to the
+Gemini API. The resulting numerical array is then formatted before being passed
+to your database source.
+
+### Dimension Matching
+
+The `dimension` field must match the expected size of your database column
+(e.g., a `vector(768)` column in PostgreSQL). This setting is supported by newer
+models since 2024 only. You cannot set this value if using the earlier model
+(`models/embedding-001`). Check out [available Gemini models][modellist] for more
+information.
+
+[modellist]:
+    https://docs.cloud.google.com/vertex-ai/generative-ai/docs/embeddings/get-text-embeddings#supported-models
+
+## Example
+
+```yaml
+embeddingModels:
+  gemini-model:
+    kind: gemini
+    model: gemini-embedding-001
+    apiKey: ${GOOGLE_API_KEY}
+    dimension: 768
+```
+
+{{< notice tip >}}
+Use environment variable replacement with the format ${ENV_NAME}
+instead of hardcoding your secrets into the configuration file.

 ### Aspect Search
 To search for entries based on their attached aspects, use the following query syntax.
 
-aspect:x	Matches x as a substring of the full path to the aspect type of an aspect that is attached to the entry, in the format projectid.location.ASPECT_TYPE_ID
-aspect=x	Matches x as the full path to the aspect type of an aspect that is attached to the entry, in the format projectid.location.ASPECT_TYPE_ID
-aspect:xOPERATORvalue	
-Searches for aspect field values. Matches x as a substring of the full path to the aspect type and field name of an aspect that is attached to the entry, in the format projectid.location.ASPECT_TYPE_ID.FIELD_NAME
+`has:x`
+Matches `x` as a substring of the full path to the aspect type of an aspect that is attached to the entry, in the format `projectid.location.ASPECT_TYPE_ID`
 
-The list of supported {OPERATOR}s depends on the type of field in the aspect, as follows:
-- String: = (exact match) and : (substring)
-- All number types: =, :, <, >, <=, >=, =>, =<
-- Enum: =
-- Datetime: same as for numbers, but the values to compare are treated as datetimes instead of numbers
-- Boolean: =
+`has=x`
+Matches `x` as the full path to the aspect type of an aspect that is attached to the entry, in the format `projectid.location.ASPECT_TYPE_ID`
 
-Only top-level fields of the aspect are searchable. For example, all of the following queries match entries where the value of the is-enrolled field in the employee-info aspect type is true. Other entries that match on the substring are also returned.
-- aspect:example-project.us-central1.employee-info.is-enrolled=true
-- aspect:example-project.us-central1.employee=true
-- aspect:employee=true
+`xOPERATORvalue`
+Searches for aspect field values. Matches x as a substring of the full path to the aspect type and field name of an aspect that is attached to the entry, in the format `projectid.location.ASPECT_TYPE_ID.FIELD_NAME`
+
+The list of supported operators depends on the type of field in the aspect, as follows:
+* **String**: `=` (exact match)
+* **All number types**: `=`, `:`, `<`, `>`, `<=`, `>=`, `=>`, `=<`
+* **Enum**: `=` (exact match only)
+* **Datetime**: same as for numbers, but the values to compare are treated as datetimes instead of numbers
+* **Boolean**: `=`
+
+Only top-level fields of the aspect are searchable.
+
+* Syntax for system aspect types:
+    * `ASPECT_TYPE_ID.FIELD_NAME`
+    * `dataplex-types.ASPECT_TYPE_ID.FIELD_NAME`
+    * `dataplex-types.LOCATION.ASPECT_TYPE_ID.FIELD_NAME`
+For example, the following queries match entries where the value of the `type` field in the `bigquery-dataset` aspect is `default`:
+    * `bigquery-dataset.type=default`
+    * `dataplex-types.bigquery-dataset.type=default`
+    * `dataplex-types.global.bigquery-dataset.type=default`
+* Syntax for custom aspect types:
+    * If the aspect is created in the global region: `PROJECT_ID.ASPECT_TYPE_ID.FIELD_NAME`
+    * If the aspect is created in a specific region: `PROJECT_ID.REGION.ASPECT_TYPE_ID.FIELD_NAME`
+For example, the following queries match entries where the value of the `is-enrolled` field in the `employee-info` aspect is `true`.
+    * `example-project.us-central1.employee-info.is-enrolled=true`
+    * `example-project.employee-info.is-enrolled=true`

 You can negate a predicate with a - (hyphen) or NOT prefix. For example, -name:foo returns resources with names that don't match the predicate foo.
 Logical operators are case-sensitive. `OR` and `AND` are acceptable whereas `or` and `and` are not.
 
+### Abbreviated syntax
+
+An abbreviated search syntax is also available, using `|` (vertical bar) for `OR` operators and `,` (comma) for `AND` operators.
+
+For example, to search for entries inside one of many projects using the `OR` operator, you can use the following abbreviated syntax:
+
+`projectid:(id1|id2|id3|id4)`
+
+The same search without using abbreviated syntax looks like the following:
+
+`projectid:id1 OR projectid:id2 OR projectid:id3 OR projectid:id4`
+
+To search for entries with matching column names, use the following:
+
+* **AND**: `column:(name1,name2,name3)`
+* **OR**: `column:(name1|name2|name3)`
+
+This abbreviated syntax works for the qualified predicates except for `label` in keyword search.

 ### Request
 1. Always try to rewrite the prompt using search syntax.
