Configuring

Unified configuration management across AI coding environments. Load environment variables, secrets, and other opinionated configuration setups from any AI coding platform.

Quick Start

import sys
sys.path.insert(0, '/path/to/claude-skills')  # or wherever skills are installed
from configuring import get_env, detect_environment

# Get a variable (searches all sources automatically)
token = get_env("TURSO_TOKEN", required=True)

# With default
port = get_env("PORT", default="8080")

# What environment are we in?
env = detect_environment()  # "claude.ai", "claude-code-desktop", "codex", "jules", etc.

Supported Environments

| Environment | Config Sources |

|-------------|----------------|

| Claude.ai Projects | /mnt/project/*.env, /mnt/project/*-token.txt |

| Claude Code | ~/.claude/settings.json (env block), .claude/settings.json |

| OpenAI Codex | ~/.codex/config.toml, setup script → ~/.bashrc, shell_snapshots/*.sh |

| Jules | Environment settings UI, .env in repo |

| Universal | os.environ, .env, .env.local |

API Reference

# Core
get_env(key, default=None, *, required=False, validator=None) -> str | None
load_env(path) -> dict[str, str]           # Load specific file
load_all(force_reload=False) -> dict       # Load all sources

# Utilities
detect_environment() -> str                 # Current platform
mask_secret(value, show_chars=4) -> str    # Safe logging
debug_info() -> dict                        # Troubleshooting
get_loaded_sources() -> list[str]          # What was checked

Credential File Formats

.env files (KEY=value):

TURSO_TOKEN=eyJhbGciOiJFZERTQSI...
EMBEDDING_API_KEY=sk-svcacct-...

Single-value files (*-token.txt, *-key.txt):

eyJhbGciOiJFZERTQSI...

Filename becomes key: turso-token.txt → TURSO_TOKEN

Claude Code settings.json:

{
  "env": {
    "TURSO_TOKEN": "eyJhbGciOiJFZERTQSI..."
  }
}

Priority Order

Later sources override earlier:

OS environment variables
Platform-specific sources (detected automatically)
.env files in cwd
OS environment variables (again - explicit exports always win)

Debugging

import sys
sys.path.insert(0, '/path/to/claude-skills')
from configuring import debug_info
print(debug_info())
# {'environment': 'claude.ai', 'sources': ['os.environ', 'claude.ai:/mnt/project/'], ...}

CLI:

cd /path/to/claude-skills/configuring
python scripts/getting_env.py                    # Show debug info
python scripts/getting_env.py TURSO_TOKEN        # Get specific key

Migration from api-credentials / getting-env

Replace:

# Old (api-credentials)
from credentials import get_anthropic_api_key
key = get_anthropic_api_key()

# Old (getting-env)
from getting_env import get_env
key = get_env("ANTHROPIC_API_KEY")

# New (configuring)
import sys
sys.path.insert(0, '/path/to/claude-skills')
from configuring import get_env
key = get_env("ANTHROPIC_API_KEY", required=True)

Hook Development

by anthropics

vendor ×2

This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.

Build agentic applications with GitHub Copilot SDK. Use when embedding AI agents in apps, creating custom tools, implementing streaming responses, managing sessions, connecting to MCP servers, or creating custom agents. Triggers on Copilot SDK, GitHub SDK, agentic app, embed Copilot, programmable agent, MCP server, custom agent.

Coding Agent Session Search - unified CLI/TUI to index and search local coding agent history from Claude Code, Codex, Gemini, Cursor, Aider, ChatGPT, Pi-Agent, Factory, and more. Purpose-built for AI agent consumption with robot mode.

Destructive Command Guard - High-performance Rust hook for Claude Code that blocks dangerous commands before execution. SIMD-accelerated, modular pack system, whitelist-first architecture. Essential safety layer for agent workflows.

Makepad UI development skills for Rust apps: setup, patterns, shaders, packaging, and troubleshooting.

Secure environment variable management ensuring secrets are never exposed in Claude sessions, terminals, logs, or git commits

How to use it

Copy the folder

Take oaustegard/configuring from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
