The relevant documentation for your detected language is included below in <doc> tags. Each tag has a path attribute showing its original file path. Use this to find the right section:

Quick Task Reference

Single text classification/summarization/extraction/Q&A: → Refer to {lang}/claude-api/README.md

Chat UI or real-time response display: → Refer to {lang}/claude-api/README.md + {lang}/claude-api/streaming.md

Long-running conversations (may exceed context window): → Refer to {lang}/claude-api/README.md — see Compaction section

Migrating to a newer model or replacing a retired model: → Refer to shared/model-migration.md

Prompt caching / optimize caching / "why is my cache hit rate low": → Refer to shared/prompt-caching.md + {lang}/claude-api/README.md (Prompt Caching section)

Count tokens in a file / prompt / diff ("how many tokens is X"): → Refer to shared/token-counting.md — use messages.count_tokens, never tiktoken

Function calling / tool use / agents: → Refer to {lang}/claude-api/README.md + shared/tool-use-concepts.md + {lang}/claude-api/tool-use.md

Batch processing (non-latency-sensitive): → Refer to {lang}/claude-api/README.md + {lang}/claude-api/batches.md
