SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Managing API keys across multiple projects is error‑prone and insecure when each credential is stored or entered separately, leading to duplication, accidental exposure, and broken environments.

Core Features & Use Cases

Multi‑format parsing: Reads Access.txt files in colon‑separated, key‑value, or informal layouts.
Regex extraction: Identifies keys for services such as OpenAI, Anthropic, Render, Reddit, Supabase, and many others.
Automatic validation: Sends lightweight API calls to confirm each key’s validity before use.
.env generation: Writes discovered credentials to a project’s .env file and updates .gitignore.
Missing‑key reporting: Alerts the user to any required credentials that were not found and provides guidance.

Quick Start

Ask the credentials skill to load my API keys from ~/Documents/Access.txt and create a .env file for the project.

FAQPage Schema

How do I load API keys from an Access.txt file into a project .env?▼

It reads Access.txt files in colon-separated, key-value, or informal layouts, uses regex extraction to identify credentials for services like OpenAI and Anthropic, and writes them directly into your project's .env file.

What is the best way to validate environment variables for services like OpenAI and Anthropic before running a script?▼

The Skill validates API keys by sending lightweight API calls to confirm each credential's validity before use, alerting you to any missing or invalid keys with guidance on resolving the issue.

Can I extract API keys from informal text layouts without strict key-value formatting?▼

Yes, multi-format parsing reads Access.txt files whether they are colon-separated, key-value, or informally structured, using regex extraction to identify keys for services like Render, Reddit, and Supabase.

How do I securely manage multiple API keys across different development projects?▼

Centralize credentials in a single Access.txt file to eliminate duplication and accidental exposure, automatically loading required environment variables into individual project .env files as needed.

Does the .env generation process automatically update .gitignore to protect credentials?▼

Yes, during .env generation the Skill writes discovered credentials to the .env file and automatically updates .gitignore to ensure your API keys are not accidentally committed to version control.
