Claude API build eval

Claude API is Anthropic's application programming interface for building software with Claude models. The cited material describes prompt caching, which reuses prompts to reduce token costs, along with console diagnostics for monitoring cache hit rates. The name is also used in the material for a Claude Code skill that provides awareness of Anthropic's SDKs and APIs.

A feature of Anthropic's Claude platform that packages reusable instructions, scripts, and reference files into skills that Claude can apply to specific tasks. Skills can be used in Claude applications and through Anthropic's agent-development tools.

Claude for Excel is an AI tool that brings Claude into Microsoft Excel. The video describes it as helping Citadel's investment professionals test, build, and trust their spreadsheet work.

Awesome Claude Skills is a curated GitHub resource covering reusable Claude Skills, plugins, tools, and related resources for Claude.ai, Claude Code, the Claude API, and other coding agents such as Codex, Cursor, Gemini CLI, Antigravity, and Windsurf. It organizes examples by areas including document processing, development, data analysis, communication, media, productivity, project management, security, and SaaS-app automation through Composio. The repository explains Skills as folders containing a SKILL.md file with YAML metadata and Markdown instructions, optionally accompanied by scripts, references, and assets. It documents progressive loading: agents initially see a skill's name and description, load the full instructions when relevant, and load supporting files on demand. It also distinguishes Skills, which define workflows and guardrails, from MCP servers and tools, which provide system access and individual actions. The list accepts contributions through documented quality and pull-request guidelines. The repository is licensed under Apache 2.0, while individual skills may use different licenses.

Claude is a family of large language models and service developed and hosted by Anthropic, an AI safety and research company building reliable, interpretable, and steerable AI systems. Available through Anthropic's web chat products and a commercial API, Claude accepts text prompts and structured inputs or file attachments via the API and returns natural-language and code outputs for tasks such as coding, summarization, document Q&A, and general business and productivity workflows. It is used inside Anthropic products such as Claude Code, by third-party services via Anthropic's API and enterprise agreements, and as an alternative model provider for the model-agnostic Strands Agents framework. Claude can also power applications such as banking assistants, whose generations can be traced as part of an AI application evaluation workflow.
