Improve error message for invalid action input format

[hukaidong]

This change updates the error message for cases where the action input does not meet the required JSON object format. Previously, the error simply stated that the action input wasn't a valid key-value dictionary, which led to confusion. Now, the message explains that the input must be a JSON object with key-value pairs and not a string or an array.

In some error cases, agents were providing the action input as a plain string or as a dictionary enclosed within an array. This update addresses those issues by explicitly stating that the outermost structure must be a dictionary (for example, { "key": "value" }). The goal is to help avoid ambiguity and make it clear when the error occurs due to incorrect formatting.

Overview

This pull request modifies the error message for invalid tool arguments in the English translation JSON file to improve user clarity. The changes aim to enhance guidance for users regarding the expected input format.

Findings

Message Content Changes

• Original Message:

  "tool_arguments_error": "Error: the Action Input is not a valid key, value dictionary."
  

• New Message:

  "tool_arguments_error": "Error: Invalid action input format. The input must be a JSON object with key-value pairs. Ensure the outermost structure is a dictionary (e.g., { \"key\": \"value\" }) and not an array or other type."
  

Positive Aspects

• Descriptive Guidance: The updated message provides enhanced clarity regarding the expected input, which is crucial for user experience.
• Specific Example: The new message includes a specific example of the expected format, helping users understand exactly what is required.
• Type Alerts: It alerts users about incorrect data types, which can significantly reduce confusion.
• Consistency: The message adheres to the existing format of other error messages, maintaining overall project consistency.

Suggestions for Improvement

1. Break Down the Message: To improve readability, consider adding line breaks for better visual separation:

   "tool_arguments_error": "Error: Invalid action input format.\nExpected: JSON object with key-value pairs\nExample: { \"key\": \"value\" }\nNote: Ensure the outermost structure is a dictionary, not an array or other type."
   

2. Markdown Formatting: If the system supports it, incorporating Markdown can enhance the visual presentation:

   "tool_arguments_error": "**Error**: Invalid action input format.\n- Expected: JSON object with key-value pairs\n- Example: `{ \"key\": \"value\" }`\n- Note: Ensure the outermost structure is a dictionary, not an array or other type."
   

3. Provide Additional Examples: Including more valid and invalid examples can further clarify the requirements:

   "tool_arguments_error": "Error: Invalid action input format. The input must be a JSON object with key-value pairs.\n\nValid examples:\n{ \"key\": \"value\" }\n{ \"name\": \"test\", \"value\": 123 }\n\nInvalid examples:\n[\"key\", \"value\"]\n\"string_value\""
   

Code Quality Assessment

• Clarity: 9/10 - The message is notably clearer than the original, making it user-friendly.
• Completeness: 8/10 - While informative, it could benefit from additional examples to cover more scenarios.
• Maintainability: 10/10 - The change involves a straightforward string update, making it very maintainable.
• Consistency: 9/10 - The modifications align with the style of other error messages, ensuring consistency across the application.

Recommendations Summary

• Adopt one of the suggested formatting options to improve the readability of the error message.
• Consider adding more examples of both valid and invalid input formats.
• Evaluate the potential of adding translation keys for clearer message components, supporting possible future translations.

Security Considerations

• No security issues identified; the error message remains non-intrusive to sensitive information and offers appropriate guidance levels.
