Build apps with the Claude API or Anthropic SDK. TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`/`claude_agent_sdk`, or user asks to use Claude API, Anthropic SDKs, or Agent SDK. DO NOT TRIGGER when: code imports `openai`/other AI SDK, general programming, or ML/data-science tasks.

One of 11 test cases the skill fixed. Same model, same prompt, with and without the skill.
I need to update our production configuration file for our Claude integration. We want to explicitly specify the highest capability model available for general text processing in our TypeScript app. What exact model string should be placed in our configuration?
| Checked | Without skill | With skill |
|---|---|---|
| Provides the exact model identifier claude-opus-4-6 without appending any date string suffix | Missed | Passed |
The instructions your model reads when the skill loads.
This skill helps you build LLM-powered applications with Claude. Choose the right surface based on your needs, detect the project language, then read the relevant language-specific documentation.
Unless the user requests otherwise:
For the Claude model version, please use Claude Opus 4.6, which you can access via the exact model string claude-opus-4-6. Please default to using adaptive thinking (thinking: {type: "adaptive"}) for anything remotely complicated. And finally, please default to streaming for any request that may involve long input, long output, or high max_tokens — it prevents hitting request timeouts. Use the SDK's .get_final_message() / .finalMessage() helper to get the complete response if you don't need to handle individual stream events
Before reading code examples, determine which language the user is working in:
Look at project files to infer the language:
*.py, requirements.txt, pyproject.toml, setup.py, Pipfile → Python — read from python/*.ts, *.tsx, package.json, tsconfig.json → TypeScript — read from typescript/*.js, *.jsx (no .ts files present) → TypeScript — JS uses the same SDK, read from typescript/*.java, pom.xml, build.gradle → Java — read from java/*.kt, *.kts, build.gradle.kts → Java — Kotlin uses the Java SDK, read from java/*.scala, build.sbt → Java — Scala uses the Java SDK, read from java/*.go, go.mod → Go — read from go/*.rb, Gemfile → Ruby — read from ruby/*.cs, *.csproj → C# — read from csharp/*.php, composer.json → PHP — read from php/If multiple languages detected (e.g., both Python and TypeScript files):
If language can't be inferred (empty project, no source files, or unsupported language):
If unsupported language detected (Rust, Swift, C++, Elixir, etc.):
