I was experimenting with wasmtime-py today and found the current documentation didn't quite give me the information that I needed.
The package has a solid looking test suite, so I decided to see if I could generate additional documentation based on that.
I started with a checkout of the repo:
cd /tmp
git clone https://github.com/bytecodealliance/wasmtime-py
The tests are all in the test/
folder, so I used my files-to-prompt tool to turn every .py
file in that folder into a single prompt, using the XML-ish format that Claude likes (the -c
option):
files-to-prompt wasmtime-py/tests -e py -c
Piping that through ttok shows that it's about 34,780 OpenAI tokens. I pasted the whole thing ( | pbcopy
to copy to my clipboard) into my Claude token counter tool and got 43,490 - easily enough to fit Claude 3.5 Sonnet's 200,000 limit.
So I ran this:
files-to-prompt -e py wasmtime-py/tests -c | \
llm -m claude-3.5-sonnet -s \
'write detailed usage documentation including realistic examples'
I'm using llm-claude-3 here and a system prompt of:
write detailed usage documentation including realistic examples
Here's a short excerpt of the result:
from wasmtime import Engine, Store # Create an engine engine = Engine() # Create a store store = Store(engine)The Engine handles compilation settings and caching. The Store holds runtime state for instances.
from wasmtime import Module # From WAT text format module = Module(engine, '(module)') # From binary Wasm with open('module.wasm', 'rb') as f: module = Module(engine, f.read())
You can see the full transcript here, saved using llm logs -c | pbcopy
(I then hand-edited in a <details><summary>
to hide the lengthy piped input). As always I'm sharing the transcript in a private Gist to keep this AI-generated, unverified text from being indexed by search engines.
At the end of the first chunk of output Claude offered the following:
This documentation covers the core functionality. The bindings also support more advanced features like:
- Component model and interface types
- Resource types and references
- Custom linking and importing
- Memory management controls
- Execution limits and interruption
Let me know if you would like me to expand on any of these topics!
So I followed up with another prompt (using llm -c
for "continue current conversation"):
llm -c 'write a detailed section about memory management and one about execution limits'
This produced a useful continuation of the documentation.
How good is this documentation? It's pretty solid! The only thing it had to go on was the content of those tests, so I can be reasonably confident it didn't make any glaringly terrible mistakes and that the examples it gave me are more likely than not to execute.
Someone with more depth of experience with the project than me could take this as an initial draft and iterate on it to create verified, generally useful documentation.
