Optimized `parse_pokemon_types` by adding a private `_parse_types_json` helper decorated with `@functools.lru_cache(maxsize=1024)`. The helper returns an immutable tuple to prevent cache pollution and the public function casts it back to a list. This significantly speeds up repeated parsing of identical JSON strings, which is common when processing lists of Pokemon.

💡 What:
Optimized
parse_pokemon_typesinsrc/app/schemas/pokemon.pyby adding a private_parse_types_jsonhelper decorated with@functools.lru_cache(maxsize=1024). The helper returns an immutable tuple to prevent cache pollution and the public function casts it back to a list. Also added a journal entry in.jules/bolt.md.🎯 Why:
Pydantic validators that parse JSON strings (like
parse_pokemon_typesmapping DB strings to lists) are called repeatedly, sometimes thousands of times per request if fetching a large list. Directjson.loadscalls become a noticeable CPU bottleneck.📊 Impact:
Massive speedup for repeated parsing. In local benchmarks, parsing 100,000 identical JSON strings went from ~0.25s (uncached) to ~0.04s (cached). Reduces CPU overhead and response times when returning lists of Pokemon.
🔬 Measurement:
Verified functionality using
PYTHONPATH=src python3 -m pytest tests/test_pokemon_schemas.pyand the full suite. Also wrote a local test script parsing identical strings 100k times to measure the timing difference.PR created automatically by Jules for task 1808085092818188109 started by @edsonesf
