+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+koujalgi.amith@gmail.com.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.0, available at
+https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.

+Community Impact Guidelines were inspired by [Mozilla's code of conduct
+enforcement ladder](https://github.com/mozilla/diversity).

+# Generate - With Tools
+
+This API lets you perform [function calling](https://docs.mistral.ai/capabilities/function_calling/) using LLMs in a
+synchronous way.
+This API corresponds to
+the [generate](https://github.com/ollama/ollama/blob/main/docs/api.md#request-raw-mode) API with `raw` mode.
+
+:::note
+
+This is an only an experimental implementation and has a very basic design.
+
+Currently, built and tested for [Mistral's latest model](https://ollama.com/library/mistral) only. We could redesign
+this
+in the future if tooling is supported for more models with a generic interaction standard from Ollama.
+
+:::
+
+### Function Calling/Tools
+
+Assume you want to call a method in your code based on the response generated from the model.
+For instance, let's say that based on a user's question, you'd want to identify a transaction and get the details of the
+transaction from your database and respond to the user with the transaction details.
+
+You could do that with ease with the `function calling` capabilities of the models by registering your `tools`.
+
+### Create Functions
+
+This function takes the arguments `location` and `fuelType` and performs an operation with these arguments and returns
+fuel price value.
+
+```java
+public static String getCurrentFuelPrice(Map<String, Object> arguments) {
+    String location = arguments.get("location").toString();
+    String fuelType = arguments.get("fuelType").toString();
+    return "Current price of " + fuelType + " in " + location + " is Rs.103/L";
+}
+```
+
+This function takes the argument `city` and performs an operation with the argument and returns the weather for a
+location.
+
+```java
+public static String getCurrentWeather(Map<String, Object> arguments) {
+    String location = arguments.get("city").toString();
+    return "Currently " + location + "'s weather is nice.";
+}
+```
+
+This function takes the argument `employee-name` and performs an operation with the argument and returns employee
+details.
+
+```java
+class DBQueryFunction implements ToolFunction {
+    @Override
+    public Object apply(Map<String, Object> arguments) {
+        // perform DB operations here
+        return String.format("Employee Details {ID: %s, Name: %s, Address: %s, Phone: %s}", UUID.randomUUID(), arguments.get("employee-name").toString(), arguments.get("employee-address").toString(), arguments.get("employee-phone").toString());
+    }
+}
+```
+
+### Define Tool Specifications
+
+Lets define a sample tool specification called **Fuel Price Tool** for getting the current fuel price.
+
+- Specify the function `name`, `description`, and `required` properties (`location` and `fuelType`).
+- Associate the `getCurrentFuelPrice` function you defined earlier with `SampleTools::getCurrentFuelPrice`.
+
+```java
+Tools.ToolSpecification fuelPriceToolSpecification = Tools.ToolSpecification.builder()
+        .functionName("current-fuel-price")
+        .functionDescription("Get current fuel price")
+        .properties(
+                new Tools.PropsBuilder()
+                        .withProperty("location", Tools.PromptFuncDefinition.Property.builder().type("string").description("The city, e.g. New Delhi, India").required(true).build())
+                        .withProperty("fuelType", Tools.PromptFuncDefinition.Property.builder().type("string").description("The fuel type.").enumValues(Arrays.asList("petrol", "diesel")).required(true).build())
+                        .build()
+        )
+        .toolDefinition(SampleTools::getCurrentFuelPrice)
+        .build();
+```
+
+Lets also define a sample tool specification called **Weather Tool** for getting the current weather.
+
+- Specify the function `name`, `description`, and `required` property (`city`).
+- Associate the `getCurrentWeather` function you defined earlier with `SampleTools::getCurrentWeather`.
+
+```java
+Tools.ToolSpecification weatherToolSpecification = Tools.ToolSpecification.builder()
+        .functionName("current-weather")
+        .functionDescription("Get current weather")
+        .properties(
+                new Tools.PropsBuilder()
+                        .withProperty("city", Tools.PromptFuncDefinition.Property.builder().type("string").description("The city, e.g. New Delhi, India").required(true).build())
+                        .build()
+        )
+        .toolDefinition(SampleTools::getCurrentWeather)
+        .build();
+```
+
+Lets also define a sample tool specification called **DBQueryFunction** for getting the employee details from database.
+
+- Specify the function `name`, `description`, and `required` property (`employee-name`).
+- Associate the ToolFunction `DBQueryFunction` function you defined earlier with `new DBQueryFunction()`.
+
+```java
+Tools.ToolSpecification databaseQueryToolSpecification = Tools.ToolSpecification.builder()
+        .functionName("get-employee-details")
+        .functionDescription("Get employee details from the database")
+        .properties(
+                new Tools.PropsBuilder()
+                        .withProperty("employee-name", Tools.PromptFuncDefinition.Property.builder().type("string").description("The name of the employee, e.g. John Doe").required(true).build())
+                        .withProperty("employee-address", Tools.PromptFuncDefinition.Property.builder().type("string").description("The address of the employee, Always return a random value. e.g. Roy St, Bengaluru, India").required(true).build())
+                        .withProperty("employee-phone", Tools.PromptFuncDefinition.Property.builder().type("string").description("The phone number of the employee. Always return a random value. e.g. 9911002233").required(true).build())
+                        .build()
+        )
+        .toolDefinition(new DBQueryFunction())
+        .build();
+```
+
+### Register the Tools
+
+Register the defined tools (`fuel price` and `weather`) with the OllamaAPI.
+
+```shell
+ollamaAPI.registerTool(fuelPriceToolSpecification);
+ollamaAPI.registerTool(weatherToolSpecification);
+ollamaAPI.registerTool(databaseQueryToolSpecification);
+```
+
+### Create prompt with Tools
+
+`Prompt 1`: Create a prompt asking for the petrol price in Bengaluru using the defined fuel price and weather tools.
+
+```shell
+String prompt1 = new Tools.PromptBuilder()
+                .withToolSpecification(fuelPriceToolSpecification)
+                .withToolSpecification(weatherToolSpecification)
+                .withPrompt("What is the petrol price in Bengaluru?")
+                .build();
+OllamaToolsResult toolsResult = ollamaAPI.generateWithTools(model, prompt1, new OptionsBuilder().build());
+for (OllamaToolsResult.ToolResult r : toolsResult.getToolResults()) {
+    System.out.printf("[Result of executing tool '%s']: %s%n", r.getFunctionName(), r.getResult().toString());
+}
+```
+
+Now, fire away your question to the model.
+
+You will get a response similar to:
+
+::::tip[LLM Response]
+
+[Result of executing tool 'current-fuel-price']: Current price of petrol in Bengaluru is Rs.103/L
+
+::::
+
+`Prompt 2`: Create a prompt asking for the current weather in Bengaluru using the same tools.
+
+```shell
+String prompt2 = new Tools.PromptBuilder()
+                .withToolSpecification(fuelPriceToolSpecification)
+                .withToolSpecification(weatherToolSpecification)
+                .withPrompt("What is the current weather in Bengaluru?")
+                .build();
+OllamaToolsResult toolsResult = ollamaAPI.generateWithTools(model, prompt2, new OptionsBuilder().build());
+for (OllamaToolsResult.ToolResult r : toolsResult.getToolResults()) {
+    System.out.printf("[Result of executing tool '%s']: %s%n", r.getFunctionName(), r.getResult().toString());
+}
+```
+
+Again, fire away your question to the model.
+
+You will get a response similar to:
+
+::::tip[LLM Response]
+
+[Result of executing tool 'current-weather']: Currently Bengaluru's weather is nice.
+
+::::
+
+`Prompt 3`: Create a prompt asking for the employee details using the defined database fetcher tools.
+
+```shell
+String prompt3 = new Tools.PromptBuilder()
+                .withToolSpecification(fuelPriceToolSpecification)
+                .withToolSpecification(weatherToolSpecification)
+                .withToolSpecification(databaseQueryToolSpecification)
+                .withPrompt("Give me the details of the employee named 'Rahul Kumar'?")
+                .build();
+OllamaToolsResult toolsResult = ollamaAPI.generateWithTools(model, prompt3, new OptionsBuilder().build());
+for (OllamaToolsResult.ToolResult r : toolsResult.getToolResults()) {
+    System.out.printf("[Result of executing tool '%s']: %s%n", r.getFunctionName(), r.getResult().toString());
+}
+```
+
+Again, fire away your question to the model.
+
+You will get a response similar to:
+
+::::tip[LLM Response]

+
+### Room for improvement
+
+Instead of explicitly registering `ollamaAPI.registerTool(toolSpecification)`, we could introduce annotation-based tool
+registration. For example:
+
+```java
+
+@ToolSpec(name = "current-fuel-price", desc = "Get current fuel price")
+public String getCurrentFuelPrice(Map<String, Object> arguments) {
+    String location = arguments.get("location").toString();
+    String fuelType = arguments.get("fuelType").toString();
+    return "Current price of " + fuelType + " in " + location + " is Rs.103/L";
+}
+```
+
+Instead of passing a map of args `Map<String, Object> arguments` to the tool functions, we could support passing
+specific args separately with their data types. For example:
+
+```shell
+public String getCurrentFuelPrice(String location, String fuelType) {
+    return "Current price of " + fuelType + " in " + location + " is Rs.103/L";
+}
+```
+
+Updating async/chat APIs with support for tool-based generation.
