Code documentation writer: how to document functions
The Code documentation writer tool creates textual descriptions for supplied functions: parameters, return values, usage examples and limitations. It is a web form with two fields: 'Code and error message' and 'Platform or application'. You select the output language, press Generate and receive one result in a separate panel, which you can copy or download as plain text TXT. The tool does not execute code and does not check it for errors: it interprets structure and syntax, so the result may contain inaccuracies. Below is how to prepare the input, what to check in the response and what constraints to consider.
Open tool: Code documentation writer ↗What the tool actually does
"Code documentation writer" analyzes the supplied fragment and forms a textual description of functions: purpose, input parameters, return values, call examples and possible limitations. This is convenient when you need to quickly get a draft of code explanations or prepare the basis for comments in a project.
The tool does not run code and does not check it for errors. It relies on syntax and structure recognition, so for non‑standard constructs, decorators, asynchronous functions or languages with dynamic typing the description may be incomplete. The model may make mistakes, and queue and service availability may change.
This is a text assistant: it does not create images, audio or video and is not intended for working with secrets. Do not insert keys, passwords or personal data into the code field.
Input example: def add(a, b): return a + b
Preparing the 'Code and error message' and 'Platform or application' fields
Enter the code fragment you want to document into the first field. Maximum length is 8000 characters. Best results come from individual functions or small modules: the more compact the fragment, the more accurate the description. If the code is long, split it into parts and process each separately.
In the second field specify the language, framework or environment: for example, Python 3.10, JavaScript Node.js, Java Spring. Maximum length is 1000 characters. Platform context helps interpret syntax and language features more accurately.
Avoid incomplete fragments without context and irrelevant details. Meaningful variable names and concise comments improve the result, but do not overload the code.
Code: def add(a, b): return a + b Platform: Python 3.10
How to complete the task: step‑by‑step instruction
Step 1. Open the web form. Fill the 'Code and error message' and 'Platform or application' fields according to the recommendations above.
Step 2. Select the output language. Press Generate. Processing usually takes a few seconds, but may take longer under high load.
Step 3. The result appears in a separate panel. It can be copied or downloaded as plain text TXT. The form does not save history and does not support batch processing: it accepts one fragment at a time. If the result is unsatisfactory, refine the code or platform description and try again.
After pressing Generate you will get text with sections: Description, Parameters, Return value, Example, Limitations.
Checking the result: quality criteria
Check that all function parameters are described. For each, purpose and, if known, type and possible values should be indicated. Default values should also be reflected.
Ensure the returned value is described correctly. If the function returns None or nothing, this must be explicitly stated. Call examples should be syntactically correct and show typical usage.
Limitations should include conditions under which the function may malfunction: division by zero, overflow, invalid argument types. If the tool missed an important limitation, add it manually. Final verification is always your responsibility.
For the add(a, b) function good documentation will state: parameters a and b are numbers; returns their sum; example: add(2, 3) -> 5; limitation: does not check argument types.
Tool limitations and typical errors
The tool does not execute code, so it cannot detect logical errors or runtime errors. It does not support OCR, does not work with images and does not generate audio. All output is text only.
The model may misinterpret unfamiliar libraries or syntax. For decorators, asynchronous functions and rare languages the description may be incomplete. Documentation quality depends on input clarity.
Do not upload documents and do not expect batch processing. There is no automatic saving and no integrations with version‑control systems. All actions are manual.
If the code contains an error, the tool will not report it but will simply generate documentation based on what it sees.
Practical example: documenting a Python function
Consider the function: def add(a, b): return a + b. Insert this line into the code field. In the platform field specify Python 3.10. Select Russian as the output language and press Generate.
The tool may output something like: Function add takes two arguments a and b, returns their sum. Parameters: a – number, b – number. Return value: sum of a and b. Example: add(2, 3) returns 5. Limitations: does not check argument types, may raise an error when adding incompatible types.
Verify that the description matches the code. If the function is meant to work only with numbers, add this limitation manually. If the tool made a mistake, correct the text. The ready result can be copied or downloaded as TXT.
Input: def add(a, b): return a + b Output: Function add... (documentation text)
Tips for effective use
The more structured your code, the better the result. Use meaningful variable names and add comments if they help explain the purpose. But do not overload the code with unnecessary details.
If the function is large, split it into logical parts and document each separately. This simplifies checking and increases accuracy. For complex cases specify the language version and libraries in the platform field.
Do not rely entirely on automatic generation. Always check the result against the actual function behavior. The tool is an assistant, not a replacement for manual documentation.
For a function with default parameters indicate this in the description: def greet(name='World'): ...
The Code documentation writer simplifies creating drafts of documentation for functions. Prepare code and platform, select language, generate text and check it against criteria: completeness of parameters, correctness of return value, examples and limitations. Remember the limitations: the tool does not execute code, does not support images or audio, does not save data. Use it as an auxiliary means, but always verify the result manually. Following this guide you will be able to efficiently document your functions.
