AI APPLICATION DEVELOPMENT / Anthropic
Anthropic Claude API
Routes Claude API work to language-specific SDK guidance and distinguishes self-hosted tool loops from managed agent execution.
“Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER —”
01 / THE REASONING
Why this made the selection.
- Explains the operational differences among a plain API call, a tool runner, managed agents and the separate Agent SDK.
- Requires documented SDK symbols and offers named migration, prompt-audit and cost-review workflows.
02 / THE REVIEW RECORD
What we actually inspected.
Source review has boundaries.
A clear record is more useful than a “safe” badge.
Material inspected
- skills/claude-api/SKILL.md
- skills/claude-api/shared/live-sources.md
- skills/claude-api/python/claude-api/tool-use.md
- skills/claude-api/LICENSE.txt
Our findings
- The definition checks for other-provider or provider-neutral requirements before proposing Anthropic-specific edits.
- It distinguishes who supplies the agent loop from who hosts its compute, avoiding an easy SDK-versus-service confusion.
- The live-source map identifies official docs and SDK repositories; unsupported signatures are to be verified rather than inferred across languages.
Not established by this review
- Source inspection only; no skill installation or workflow execution was performed.
The review applies to the material and revision named here. A newer upstream release can change its behavior.
03 / PUT IT TO WORK
Add a skill to your workflow.
DOCUMENTED COMMAND
npx skills add https://github.com/anthropics/skills/tree/34040c9c568585f6929bedeaad110ad08f079624/skills/claude-apiCopying does not execute this command. It may retrieve a newer version than the reviewed source.
- Install the complete skill directory with its references and helpers; a copied SKILL.md alone may be incomplete.
- Choose the intended agent and project scope in the installer, then review its permissions before using the skill.
Before you start
- Node.js/npm for this installer
- An agent that supports the Agent Skills format
- Complete skill references
- Anthropic or documented cloud-provider credentials when making live calls
