No error handling around HTTP request & parsing
get_cache_client().get() may raise network-level exceptions or return non-200 responses, and BeautifulSoup parsing can fail if unexpected markup is returned.
Wrap the request in try/except and raise or log meaningful errors; consider passing a timeout.

In src/cratedb_about/hub/model.py around lines 27 to 31, the fetch method lacks
error handling for the HTTP request and HTML parsing. Wrap the call to
self.client.get(self.url) in a try/except block to catch network exceptions and
handle non-200 HTTP responses by checking the status code. Also, add a timeout
parameter to the request if supported. Similarly, catch exceptions from
BeautifulSoup parsing and raise or log meaningful errors to improve robustness.

CLI command provides no output or feedback to the user
LLMsTxtHub().fetch() silently scrapes the site and the command ends with “Ready.” Users cannot see the harvested data or where it was stored.
Consider:
- Returning the list from
fetch()and pretty-printing it (e.g. table, JSON, YAML) based on an optional--formatflag. - Catching and surfacing network errors so the CLI exits with a non-zero status on failure.

In src/cratedb_about/cli.py around lines 103 to 110, the hub CLI command calls
LLMsTxtHub().fetch() but provides no output or feedback to the user about the
fetched data or its storage location. Modify the hub function to capture the
list returned by fetch(), then pretty-print this data in a user-friendly format
such as a table, JSON, or YAML, controlled by an optional --format flag.
Additionally, add error handling to catch network or fetch-related exceptions,
log an appropriate error message, and exit the CLI with a non-zero status code
on failure.

In src/cratedb_about/hub/model.py around lines 55 to 68, the card_to_model
method lacks error handling for potential missing HTML elements and is missing a
return type annotation. Add appropriate try-except blocks to catch and handle
exceptions during HTML parsing, returning None or raising a clear error if
required elements are missing. Also, add a return type annotation indicating the
method returns an instance of LLMsTxtHubItem or None to improve code clarity and
robustness.

In src/cratedb_about/cli.py at line 4, replace the use of the pprint module with
a dedicated structured formatter suitable for production, such as the logging
module's formatters or JSON formatting. Remove the import of pprint and update
the code to output data using the chosen formatter to ensure cleaner, more
maintainable, and production-appropriate output.
