Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No credential access: failed

    Touches credential material in 2 places.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

    What it found

    • skills/claude-api/shared/evals/report/build-report-lite.mjs:28SSH private keys or config
      // `summary.json -> ~/.ssh/id_rsa`; the user later runs this builder (outside
    • skills/claude-api/shared/evals/report/runner-scaffold.mjs:112SSH private keys or config
      // ~/.ssh/id_rsa` planted after the startup preflight must not be read into

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Only contacts known or declared hosts: api.anthropic.com, github.com.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

    Hosts contacted

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned anthropics/skills at dbd4588f9e.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill enables AI agents to interact directly with the Anthropic Claude API, allowing them to send requests and receive responses from Claude models. It serves as the foundational bridge for integrating Claude's reasoning and generation capabilities into automated workflows.

When to use it

  • Triggering complex reasoning tasks that require Claude’s advanced logic.
  • Generating high-quality creative writing or code snippets on demand.
  • Automating customer support interactions using Claude’s conversational tone.
  • Integrating Claude directly into custom applications without manual API key handling.

Key capabilities

  • Direct communication with Anthropic's Claude model family.
  • Execution of standard API request/response cycles.
  • Support for various input and output formats defined by the API.

Example prompts

  • "Use the claude-api skill to summarize this long document into three key points."
  • "Call the claude-api to generate a Python script that scrapes data from a specific URL."
  • "Invoke the claude-api to draft a professional email response to a client inquiry."

Tips & gotchas

Ensure your AI agent has valid authentication credentials configured before attempting to call the API, as unauthorized requests will fail. Be mindful of rate limits imposed by Anthropic to avoid service interruptions during high-volume usage.
