Retry agent fails better

[hatkyinc2]

Background story explaining the current situation:
We can see failed to parse errors in an agent.
We try to recover using the langchain function to fix the output.

Desired new situation:
We should retry the original agent call several times hoping one of them passes as we know it's likely.

Implementation details:
Catch an agent fail in the generic agent call function, and retry the call until a hardcoded number of retries before totally failing.

To implement the retry mechanism in the callAgent function, you can follow these steps:

1. Define a constant for the maximum number of retries, for example, const MAX_RETRIES = 3;.
2. Create a loop that will iterate until the maximum number of retries is reached.
3. Inside the loop, call the GPT model using callGPT(prompt, model) and store the result in the reply variable.
4. Check if the reply is successful (i.e., it doesn't contain a failed to parse error or any other error condition). If it is successful, return the reply immediately.
5. If the reply is not successful and the maximum number of retries has been reached, throw an error or return an appropriate error message.

Here's the modified callAgent function with the retry mechanism:

const { PromptTemplate } = require("langchain/prompts");
const { callGPT } = require('../modules/gpt');

const MAX_RETRIES = 3;

async function callAgent(template, values, model) {
    const promptTemplate = PromptTemplate.fromTemplate(template);
    const prompt = await promptTemplate.format(values);

    for (let retryCount = 0; retryCount < MAX_RETRIES; retryCount++) {
        const reply = await callGPT(prompt, model);

        // Check if the reply is successful, and return it if it is.
        if (isReplySuccessful(reply)) {
            return reply;
        }
    }

    // If the maximum number of retries has been reached, throw an error or return an appropriate error message.
    throw new Error("Failed to get a successful reply after multiple retries.");
}

function isReplySuccessful(reply) {
    // Implement the logic to check if the reply is successful (e.g., it doesn't contain a failed to parse error).
    // For example:
    return !reply.includes("failed to parse");
}

module.exports = {
    callAgent
}

Make sure to replace the isReplySuccessful function with the appropriate logic to check if the reply is successful based on your specific use case.
