What is my-configurations CLAUDE.md?

Repository instructions for a personal macOS configuration collection, also called dotfiles. It manages shell settings, developer tools, Alfred workflows, and setup guides for an engineering computer.

Use them to manage shell modules, Git shortcuts, development tools, and configuration helpers for a macOS workstation.

They explain the repository's structure and its shortcuts, so changes can follow the existing configuration system instead of adding disconnected commands or settings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01542	$0.01542
Opus 5.5	$0.00617	$0.00617
Sonnet 5.5	$0.00308	$0.00308

Security

Grade A, and why

my-configurations CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repository Overview

This is a personal configuration repository ("dotfiles") for setting up and maintaining macOS development environments. It contains shell configurations, development tools settings, Alfred workflows, and comprehensive setup guides for engineering workstations.

Common Development Commands

Shell Module Management

The shell configuration system uses a modular approach with shortcuts and helpers:

# Help commands for each module
githelp      # Git shortcuts and workflows
herokuhelp   # Heroku shortcuts and workflows  
keybasehelp  # Keybase shortcuts and workflows
rubyhelp     # Ruby/Rails commands (in ror file)
shellhelp    # Shell utilities
brewhelp     # Homebrew package management
dockerhelp   # Docker container management
jshelp       # JavaScript/Node.js tools
pghelp       # PostgreSQL database operations
pythonhelp   # Python environment management

Core Git Shortcuts

gs           # git status
gcb <name>   # Create and push new branch
ggoback      # Reset all local changes
gsmi         # Update with submodules
gstats       # Show commit statistics

Ruby/Rails Development

rs           # Rails server (with spring stop)
rc           # Rails console (with spring stop)  
rt           # Run RSpec tests (with spring stop)
rbi          # Bundle install
rbu          # Bundle update
rdbr         # Reset database (drop, create, structure:load)
rbenvset     # Set local Ruby version to global

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
