What it does

API Integration Specialist is an agent skill from aiskillstore/marketplace. Expert in integrating third-party APIs with proper authentication, error handling, rate limiting, and retry logic. Use when integrating REST APIs, GraphQL endpoints, webhooks, or external services. Specializes in OAuth flows, API key management, request/response transformation, and building robust API clients.

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill-report.json`).

It sits in Backend & APIs, covering Third-party API integration, Error handling and Rate limiting. It works with GraphQL. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Integrating REST APIs
  • GraphQL endpoints
  • External services

Example prompts

  • “/api-integration-specialist”

Requirements

  • A credential in SERVICE_API_KEY
  • A credential in CLIENT_SECRET

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Authentication & Security
  2. Request/Response Handling
  3. Error Handling
  4. Rate Limiting
  5. Webhook Handling

What it can do on your machine

Read from SKILL.md and the folder at commit ad8daf7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SERVICE_API_KEY
    • CLIENT_SECRET
    • STRIPE_WEBHOOK_SECRET
    • STRIPE_SECRET_KEY
    • SENDGRID_API_KEY
    • TWILIO_AUTH_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

API Integration Specialist loads about 2.2k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 317 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 317 words (~2,232 tokens).

“Expert guidance for integrating external APIs into applications with production-ready patterns, security best practices, and comprehensive error handling.”
