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:
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
File uploads across multiple requests:
→ Refer to {lang}/claude-api/README.md + {lang}/claude-api/files-api.md
Agent design (tool surface, context management, caching strategy):
→ Refer to shared/agent-design.md
Anthropic CLI (ant) — terminal access, version-controlled agent/environment YAML, scripting:
→ Refer to shared/anthropic-cli.md
Managed Agents (server-managed stateful agents):
→ Refer to shared/managed-agents-overview.md and the rest of the shared/managed-agents-*.md files. For Python, TypeScript, and cURL, language-specific code examples live in {lang}/managed-agents/README.md. Java, Go, Ruby, and PHP also support the API — translate the calls using your SDK's patterns from {lang}/claude-api.md. C# does not currently have Managed Agents support; use raw HTTP from curl/managed-agents.md as a reference.
Error handling:
→ Refer to shared/error-codes.md
